BRAKE CONTROL SYSTEM CONTROL PRE-COLLISION BRAKE

  1. SYSTEM CONTROL

    1. If the pre-collision city sensor determines that the possibility of a collision is high, the ECU sends a pre-collision brake assist request signal to the skid control ECU. Upon receiving the signal, the skid control ECU switches the brake assist to standby mode. When the driver depresses the brake pedal, the skid control ECU operates the brake assist based on the master cylinder pressure sensor.

    2. If the pre-collision city sensor determines an unavoidable collision, the ECU sends the pre-collision brake request signal to the skid control ECU. The skid control ECU then activates the brake actuator assembly as a pre-collision brake control and decelerates the vehicle. Thus, the system helps to lessen the impact of a collision.
