Operation
RSP is an all-axle ABS solution that helps reduce vehicle speed
by applying all vehicle brakes as needed, reducing the tendency
to roll over. RSC is a rear-axle ABS solution that helps reduce
vehicle speed by applying rear vehicle brakes as needed,
reducing the tendency to roll over.
RSP or RSC focuses on reducing the vehicle’s speed below
the critical roll threshold during direction-changing maneuvers
(such as at exit ramps), lane changing, cornering, or obstacle
avoidance. It is most effective on dry, high-friction surfaces.
Advanced Stability Functions (ESP):
This function enhances
stability by sensing actual vehicle dynamics.
ESP equipped
vehicles add yaw control to the basic roll stability feature.
Vehicle Stability Control Speed Reduction:
In the case of a
potential roll event, the stability system will remove the throttle
and quickly apply brake pressure to slow the vehicle combination
below the threshold.
Steering Angle Sensor (ESP only):
This sensor enables
the advanced stability system to capture the driver’s steering
input and intervene if a yaw correction is needed. The sensor
also provides the earliest indication of an increase in lateral
acceleration that might cause a potential roll event. A steering
angle sensor provides a greater stability margin than a vehicle
that is not equipped with this sensor.
Brake Demand Sensors:
The stability control system
(RSP and ESP) was designed to supplement the driver’s
actions.
By directly measuring driver brake demand, the
system can transition seamlessly between driver-intended and
system-intended braking pressure. For example, if in a certain
maneuver, the system calculates 40 psi (276 kPa) is needed
and the driver is only applying 20 psi (138 kPa), the system
compensates automatically to deliver the needed 40 psi (276
kPa). If, however, during the same maneuver, the driver steps
on the brake pedal quickly to apply a higher (above 40 psi
[276 kPa]) braking level, the driver’s braking input overrides the
temporary change made by the system.
ABS / Stability System Interaction:
With the ABS based
stability control system, the ABS is given “priority” at the wheel
ends to manage wheel slip for optimal braking.
The ABS
functions similarly whether the stability system or the driver
applies the brakes.
