III. Noncompliance: BMW explains that the noncompliance is due to a
coding parameter issue, where the windshield wiper frequency decreases
when the vehicle is at rest and in brief intervals when the vehicle
accelerates from rest and therefore, does not meet the requirements set
forth in paragraph S4.1.1.2 and S4.1.1.3 of FMVSS No. 104.
Specifically, when the vehicle speed is 0 km/h, or when accelerating
after a stop up to a vehicle speed of 4 km/h (approximately 2.5 mph),
the wiper speed decreases.
IV. Rule Requirements: Paragraph S4.1.1.2 and S4.1.1.3 of FMVSS No.
104 include the requirements relevant to this petition. One frequency
or speed shall be at least 45 cycles per minute regardless of engine
load and engine speed. Regardless of engine speed and engine load, the
highest and one lower frequency or speed shall differ by at least 15
cycles per minute. Such lower frequency or speed shall be at least 20
cycles per minute regardless of engine speed and engine load.
V. Summary of BMW's Petition: The following views and arguments
presented in this section, ``V. Summary of BMW's Petition,'' are the
views and arguments provided by BMW. They have not been evaluated by
the Agency and do not reflect the views of the Agency. BMW describes
the subject noncompliance and contends that the noncompliance is
inconsequential as it relates to motor vehicle safety.
In support of its petition, BMW offers the following reasoning:
1. Wiper System Design/Functionality: BMW states that the subject
vehicles are equipped with a wiper system that contains a driver-
selectable setting/mode Low, a driver-selectable setting/mode High, a
driver-selectable setting/mode Auto (Rain Sensor), and a non-selectable
pre-programmed setting/mode that BMW refers to as Standstill Mode
(``Standstill''). The system function is described below:
a. Driver Selects Low Mode: If a driver selects the wiper frequency
mode Low, then wiper frequency while driving is larger than 40 cycles/
min and is model dependent as noted further in the petition. When the
vehicle comes to rest, e.g., at a stoplight, then the frequency
decreases. The decreased frequency is also present in the brief period
of time when the vehicle accelerates from 0 mph to 2.5 mph. This
decreased frequency is the frequency of the Standstill mode and is due
to a pre-programmed comfort function described further below. The wiper
frequency quickly and automatically returns to its selected mode, in
this case, Low, as soon as the vehicle reaches 2.5mph.
b. Driver Selects High Mode: If a driver selects wiper frequency
High mode, then wiper frequency while driving is larger than 56 cycles/
min and is model dependent as noted further in the petition. When the
vehicle comes to rest, e.g., at a stoplight, then the frequency
decreases. The decreased frequency is also present in the brief period
of time when the vehicle accelerates from 0 mph to 2.5 mph. The
decreased frequency is the frequency of the Low setting/mode and is due
to the pre-programmed comfort function described further below. The
wiper frequency quickly and automatically returns to its selected mode,
in this case, High, as soon as the vehicle reaches 2.5 mph.
c. Auto (Rain Sensor) Mode: If the driver selects Auto (Rain
Sensor) mode, then wiper frequency while driving is a function of the
amount of rain detected on the windshield by the rain sensor. Depending
upon the amount of rain, the system will provide an appropriate wiper
frequency up to the maximum wiper system frequency, which is larger
than the FMVSS No. 104 S4.1.1.2 requirement of 45 cycles/min.
d. Comfort Function: The decrease in wiper frequency when the
vehicle is at rest is a ``comfort function'' and was introduced
because, at vehicle rest, the amount of water on the windshield
compared to the amount of water on the windshield on a moving vehicle
is significantly less. The comfort function was introduced to allow the
driver to focus on the driving task and surroundings, and not be
distracted (or annoyed) by a wiper system in which the higher frequency
(when the vehicle was moving) is not needed when the vehicle is at
rest. At vehicle rest (and during acceleration from 0 mph to 2.5 mph),
the frequency is decreased briefly
[[Page 21786]]
from either High to Low, or from Low to Standstill, and then quickly
and automatically increases again to the prior driver-selected
frequency when the vehicle reaches 2.5 mph.
e. Driver Can Increase Wiper Frequency While Vehicle is at Rest:
The driver can also, while the vehicle is at rest, increase the wiper
frequency.
If the driver had selected wiper frequency mode Low, then when the
vehicle comes to rest, the frequency will decrease to Standstill. In
this case, if the driver perceives a need to increase the frequency
while the vehicle is momentarily at rest, the driver can quickly and
easily increase the frequency by moving the wiper arm/control upward.
The wiper frequency will increase from Standstill to High. When the
vehicle accelerates, the frequency will remain at High. If desired, the
driver can then decrease the frequency to Low again.
If the driver had selected wiper frequency mode High, then when the
vehicle comes to rest, the frequency will decrease to Low. In this
case, if the driver perceives a need to increase the frequency while
the vehicle is momentarily at rest, the driver can quickly and easily
increase the frequency by moving the wiper arm/control first downward
and then upward. The wiper frequency will increase from Low to High.
When the vehicle accelerates, the frequency will remain at High.
2. Test Results: BMW tested the vehicles and the test results are
contained in Table 1 of the petition.
In this petition, although there are more than five vehicle models
potentially affected, 5 wiper systems account for the systems installed
across all vehicle models. In some cases, only one vehicle model was
tested for a given wiper system, such as the 8 Series Gran Coupe,
whereas, in some cases, more than one vehicle model was tested for a
given wiper system, such as the X5 SAV and X6 SAC, and also the Z4 and
Supra.
Entries in the table for the 2 Series, 3 Series, and 4 Series
suggest that these vehicles comply with FMVSS No. 104 Sections 4.1.1.2
and 4.1.1.3. However, due to wiper system tolerances, a slight or
marginal noncomplying condition could occur.
The wiper frequencies (cycles/min) in Table 1 of the petition are
based upon actual measurements of wiper movement on the subject
vehicles during a three-minute time period and then adjusted for a one-
minute time period to denote wiper frequency in units of cycles/min. To
assess the accuracy of the three-minute count (and the cycles/minute
equivalency), a control was used in which a time period was measured
for a wiper frequency consisting of 10 wipe cycles. Using this control,
wiper frequency in cycles/min was calculated and then assessed against
the actual measured three-minute count (adjusted to the equivalent
frequency for a one-minute time period) as a check.
As noted earlier, if the driver selected wiper frequency High, then
due to the comfort function, at vehicle rest (and between 0 mph and 2.5
mph), wiper frequency changes to Low. The ``High @ . . .'' column
indicates that some models have a reduced wiper frequency of either 41
cycles/min or 42 cycles/min.
Similarly, if the driver selected wiper frequency Low, then due to
the comfort function, at vehicle rest (and between 0 mph and 2.5 mph),
wiper frequency changes to Standstill. The ``Low @ . . .'' column
indicates that the Z4 and Supra have a reduced wiper frequency of 19.8
cycles/min.
3. Wiper Frequency Comparisons
a. Wiper Frequency High: FMVSS No. 104 Section 4.1.1.2 requires a
minimum wiper frequency of 45 cycles/min. In some vehicle models, the
frequency is 41 cycles/min. A wiper frequency of 45 cycles/min equates
to a single wipe cycle of approximately 1.33 seconds. A wiper frequency
of 41 cycles/min equates to a single wipe cycle of 1.46 seconds. The
difference is approximately 0.13 seconds and is unlikely to affect
driver visibility as explained further below in the section comparing a
stationary vehicle with a moving vehicle regarding the amount of water
on the windshield.
b. Wiper Frequency Low: FMVSS 104 Section 4.1.1.3 requires a
minimum wiper frequency of 20 cycles/min. In some vehicle models, the
frequency is 19.8 cycles/min. A wiper frequency of 20 cycles/min
equates to a single wipe cycle of approximately 3.00 seconds. A wiper
frequency of 19.8 cycles/min equates to a single wipe cycle of 3.03
seconds. The difference is approximately 0.03 seconds and is extremely
unlikely to affect driver visibility as explained further below in the
section comparing a stationary vehicle with a moving vehicle regarding
the amount of water on the windshield.
4. Vehicle Travels Very Small Distance When Accelerating from 0 mph
to 2.5 mph:
In the brief interval during vehicle acceleration from 0 mph to 2.5
mph, an average vehicle travels only a small amount, approximately 1
ft. and, at that point (distance), the driver-selected wiper frequency,
i.e., either Low or High, is quickly and automatically re-established.
5. Rain Volume Comparison Between a Vehicle at Rest and a Moving
Vehicle:
In a given period of time, the volume of water on the windshield
while the vehicle is at rest is significantly less than the volume of
water on the windshield while the vehicle is moving, for example at
city or highway speeds. For example, the amount of water on the
windshield while the vehicle is at rest is approximately 50% less than
the amount of water on the windshield when driving at approximately 25
mph. Therefore, if wiper frequencies of 20 cycles/min and 45 cycles/min
are deemed to be sufficient when driving then, when the vehicle is at
rest, wiper frequencies of 19.8 cycles/min and 41 cycles/min are
sufficient for an overview of the traffic and roadway conditions. As
noted earlier, there is only a 0.13 second difference in time for a
single wipe cycle between the required 45 cycles/min and the 41 cycles/
min condition, and only a 0.03 second difference in time for a single
wipe cycle between the required 20 cycles/min and the 19.8 cycles/min
condition.
For a given rainfall velocity, driver visibility while the vehicle
is at rest with this slight or marginal noncompliance is greater than
driver visibility while the vehicle is moving with a compliant system,
especially when the vehicle is moving at city and highway speeds.
Another perspective involves determining an equivalent condition
between a vehicle at rest containing this slight noncompliance and a
moving vehicle that is compliant. A vehicle at rest with this slight
noncompliance, i.e., with a wiper frequency of 41 cycles/min (instead
of 45 cycles/min) has a reduced wiper frequency and, therefore, is
slightly less efficient in removing the rain from the windshield. An
equivalent condition would result in a vehicle velocity of
approximately 2.3mph. Therefore, a vehicle containing this slight
noncompliance at rest can be considered to be equivalent to a compliant
vehicle at 2.3 mph. Moreover, this pertains to the High wiper frequency
mode. If the Low wiper frequency mode is selected, the equivalent
vehicle velocity is 0.2 mph.
Driver visibility, while the vehicle is at rest with this slight or
marginal noncompliance, is greater than driver visibility while the
vehicle is moving with a compliant system, especially when the vehicle
is moving at city and highway speeds.
6. The Wiper System Does Not Decrease During Vehicle Deceleration:
[[Page 21787]]
The wiper system functionality on the vehicles that are the subject
of this petition is such that wiper frequency does not decrease during
vehicle deceleration to 0 mph. Therefore, the slight or marginal
noncompliance does not exist during vehicle deceleration, including the
small period of time when the vehicle is coming to rest, e.g.,
approaching a stoplight. In those circumstances, there could be a
vehicle already at the stoplight or a pedestrian in the crosswalk. In
these instances, the vehicles that are the subject of this petition are
fully compliant. BMW contends that the affected vehicles comply with
all other applicable provisions of FMVSS No. 104. BMW says that the
wiper system is compliant in the vast majority of driving situations/
modes, especially when wipers are needed most, i.e., while driving when
the wipers are selected by the driver to be in either ``High'' or
``Low'' setting/mode. Any potential non-compliance only occurs when the
vehicle is at rest, or in the very brief time period when accelerating
from 0 mph to 2.5 mph.
7. SAE J903 (Passenger Car Windshield Wiper Systems):
BMW says that it has reviewed the most recent release of SAE J903
and that it would appear that based upon a review of ``currently
available engineering data'' by the technical expert group responsible
for ongoing releases of SAE J903, that the currently-accepted minimum
performance requirement is 10 cycles/min. As noted in its petition,
under certain limited circumstances BMW's wiper system frequencies
(cycles/min) are at approximately 41 or 42 instead of 45, or at 19.8
instead of 20 and, in all of these conditions, all frequencies are
well-above a wiper frequency rate of 10 cycles/min. Therefore, it would
appear, according to the current version of SAE J903 that these wiper
frequency rates are also safe.
8. Field Experience:
BMW affirms that they have not received any complaints from vehicle
owners and are not aware of any accidents or injuries that have
occurred as a result of this issue. Toyota is not aware of any
accidents or injuries and has no field reports or claims relating to
this issue in Supra vehicles.
9. Vehicle Production:
BMW says that vehicle production has been corrected to conform to
FMVSS No. 104 Sections 4.1.1.2 and 4.1.1.3.
BMW concludes that the subject noncompliance is inconsequential as
it relates to motor vehicle safety and that its petition to be exempted
from providing notification of the noncompliance, as required by 49
U.S.C. 30118, and a remedy for the noncompliance, as required by 49
U.S.C. 30120, should be granted.
On February 23, 2021, BMW submitted a supplement to its petition
pertaining to a study created and conducted by BMW's Human-Factor's
group in conjunction with the technical development group responsible
for wiper systems. BMW states that the objective of this study was to
evaluate two different wiping speeds (41 rmp and 45 rpm) in two
identical vehicles and their influence on the recognizability and
legibility of traffic signs using an experimental setup. During the
standardized test, a rain simulation was used to create comparable
visibility conditions. The participants had to read out different
traffic signs to an experimenter and evaluate their recognizability
while sitting in the vehicle with the wipers on. Steady rain conditions
were simulated by applying water to the windshield. BMW contends that
there was no statistically significant difference in the self-reported
difficulty of reading the traffic signs, and there was no difference in
the recognition rate of the signs (i.e., speed limits and additional
texts). There was also no difference in the satisfaction with the
wiping performance.
BMW's complete petition and all supporting documents, including
details of the study conducted by BMW, are available by logging onto
the Federal Docket Management System (FDMS) website at: https://www.regulations.gov and by following the online search instructions to
locate the docket number as listed in the title of this notice.
NHTSA notes that the statutory provisions (49 U.S.C. 30118(d) and
30120(h)) that permit manufacturers to file petitions for a
determination of inconsequentiality allow NHTSA to exempt manufacturers
only from the duties found in sections 30118 and 30120, respectively,
to notify owners, purchasers, and dealers of a defect or noncompliance
and to remedy the defect or noncompliance. Therefore, any decision on
this petition only applies to the subject vehicles that BMW no longer
controlled at the time it determined that the noncompliance existed.
However, any decision on this petition does not relieve vehicle
distributors and dealers of the prohibitions on the sale, offer for
sale, or introduction or delivery for introduction into interstate
commerce of the noncompliant vehicles under their control after BMW
notified them that the subject noncompliance existed.
