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.

speed, thereby reducing the
tendency to roll over.
