Vehicle Controlling (FZR)

VEHICLE CONTROLLING (FZR)

Vehicle controlling (FZR) requires additional sensors to operate. The term ESP refers to the software of the system. The term FZR refers to the system controller. The TCS (ASR) system requires wheel speed sensors to monitor wheel slip and CAN bus communications to regulate engine power. In addition to these inputs, the vehicle controlling (FZR) requires a steering angle sensor, and a lateral acceleration/yaw rate sensor.

The ESP system does not take the vehicle load into account. Instead, the coefficient of friction is calculated in a 20 millisecond period, where the controller measures the rate at which the wheel speed is decelerated, as brake pressure is applied to the wheel.
