ANTI-LOCK BRAKING SYSTEM OPERATING INFORMATION PART 7: STARTING & OPERATING THE VEHICLE
– 112 – Y53-6032 (05/10)
During operation, the ECU of the Bendix Advanced ABS
system constantly compares performance models to the
vehicle’s actual movement, using the wheel speed sen-
sors of the ABS system, as well as lateral, yaw, and steer-
ing angle sensors. If the vehicle shows a tendency to
leave an appropriate travel path, or if critical threshold val-
ues are approached, the system will intervene to assist
the driver.
Roll Stability Program
Bendix RSP, an element of the overall ESP system,
addresses rollover conditions. In the case of a potential
roll event, the ECU will override the throttle and quickly
apply brake pressure various wheel ends to slow the vehi-
cle combination. The level of braking application during an
RSP event will be proportional to roll risk.
RSP Example
A Real World Example
Of How The RSP
System Operates:
Excessive speed for road
conditions creates forces
that exceed the threshold at
which a vehicle is likely to
rollover on a higher-friction
surface.
The system automatically
reduces engine torque and
applies the service brakes
(based on the projected rollover
risk) to reduce the vehicle
speed, thereby reducing the
tendency to roll over.
