Electronic Brake Control Module (EBCM)
WARNING: This page is about a different car, the 2008 Cadillac XLR. However, it is still accessible from the selected car via links, so may be relevant.
The following are the ACC system functions performed by the EBCM:
- The EBCM provides automatic braking for the ACC system. The DSCC will request vehicle deceleration via high speed GMLAN serial data circuit.
- The EBCM determines when the driver-applied brake pressure is active. The EBCM will communicate this status via the GMLAN serial data circuit to the BCM.
- The EBCM releases vehicle automatic braking when there is a throttle override by the driver pressing the accelerator.
- The EBCM predicts brake temperatures. Due to automatic braking, the brake system may overheat. When the brakes are overheated, the EBCM requests the ACC system to be temporarily shut down by the ECM until the brakes cool to a normal operating temperature.
- The EBCM calculates yaw rate and provides the yaw rate data to the DSCC for vehicle path predictions.
