Aspen 4WD V8-5.7L Hybrid (2009)
SLIP CONTROL
Slip Control increases torque to the front axle when a relative slip is detected between the front and the rear prop shafts.
Slip Control adjusts according to the vehicle speed and allows a permissible slip.
Utilizes a closed loop strategy for permissible slip and speed of engagement.
STABILITY CONTROL
Stability control modifies the torque request based upon the vehicle dynamics under the over-steer and under-steer conditions.
It monitors the yaw rate and the lateral acceleration to modify the clutch capacity to bring the vehicle back to a more neutral attitude.
Compensates for high load conditions by monitoring the vehicle acceleration and changing the torque capacity.
REGENERATIVE BRAKING STRATEGY
During the event of regenerative braking the software splits the torque indicated by the signal axle in a ratio of 47:53 front and rear respectively.
This torque split is to be modified to achieve optimum efficiency levels during a braking event.
MODES OF OPERATION
Normal Operation
This mode is achieved by the ignition being switched in the RUN position, which powers up the 5V regulator and generates the appropriate RESET for
the microprocessor. This mode also includes any required power-up system checks.
Shut Down Mode
This mode is activated when the ignition switch turned to the off position. The FDCM will perform any required Shut Down tasks prior to turning off the
5V regulator.
Limp-In Mode
This mode is entered when the FDCM has detected an error condition that prevents the system from performing its' required task. The FDCM operation
will vary depending from modified operation to total system shut down based on the failure that has occurred.
