Electronic Brake Force Distribution (EBD)
The Electronic Brake Force Distribution (EBD) function
mana
ges the distribution of the braking torque between the
front and rear axles, by limiting braking pressure to the rear
axle. This is done to prevent overslip of the rear wheels to
avoid vehicle instability, and to prevent the rear axle from
entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
The Electronic Roll Mitigation (ERM) system anticipates the
pote
ntial for wheel lift by monitoring the driver’s steering
wheel input and the speed of the vehicle. When ERM deter
-
mines that the rate of change of the steering wheel angle and
vehi
cle’s speed are sufficient to potentially cause wheel lift,
it then applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as road condi
-
tions, leaving the roadway, striking objects or other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off” mode (if
e
qui
pped). Refer to “Electronic Stability Control (ESC)” in
this section for a complete explanation of the available ESC
modes.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
dire
ctional control and stability of the vehicle under various
driving conditions. ESC corrects for oversteering or under
-
steering of the vehicle by applying the brake of the appro-
priate wheel(s) to assist in counteracting the oversteer or
u
nde
rsteer condition. Engine power may also be reduced to
help the vehicle maintain the desired path.
WARNING!
Many factors, such as vehicle loading, road conditions
and
driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.
