The wheels The front brake pressures are modulated separately for each wheel. The rear brake pressures are modulated by select low. Corner Brake Control CBC influences the brake pressures, below and within ABS thresholds, to counteract the yawing moment produced when Dynamic Stability Control DSC uses brakes and powertrain torque control to assist in maintaining the lateral stability of the vehicle. While the DSC enhances driving safety in abrupt maneuvers and in under-steer or over-steer situations that may occur in a bend. The In general: In an under-steer situation; the inner wheels are braked to counteract the yaw movement towards the outer edge The ABS module monitors the tracking stability of the vehicle using inputs from the wheel speed sensors, the steering The following interactions occur in an intervention situation: High speed CAN signal to the ECM, to reduce engine torque. Electronic Brake Force Distribution EBD limits the brake pressure applied to the rear wheels. When the brakes are applied, the weight of the vehicle transfers EBD uses the anti-lock braking hardware to automatically optimize the pressure of the rear brakes, below the point where • NOTE: Only the rear brakes are controlled by the EBD function. Electronic Traction Control ETC attempts to optimize forward traction by reducing engine torque, or by applying the brake of a spinning wheel until ETC is activated if an individual wheel speed is above that of the vehicle reference speed (positive slip) and the brake When the DSC function is selected off using the DSC switch, the engine torque reduction feature is disabled. Emergency Brake Assist EBA assists the driver in emergency braking situations by automatically maximizing the applied braking effort. There are |
