Multi-Collision Brake (MCB)

Multi-Collision Brake controls the brake automatically in the event of an accident where the airbag deploys to reduce the risk of additional accidents that may occur.

System operation

  • From the time the airbag deploys, Multi-Collision Brake monitors the force applied to the brake pedal and accelerator pedal for a short period. The system operates when the following conditions are met:

    • Vehicle speed is under 180 km/h at the time of collision.

    • The brake pedal and accelerator pedal are pressed forcefully.

  • When the driver steps on the brake pedal over a certain force whilst Multi-Collision Brake is active, the braking power takes priority over automatic braking by Multi-Collision Brake system. However, if the driver takes their foot off the brake pedal, automatic braking by Multi-Collision Brake system will maintain automatic braking.

System off

Multi-Collision Brake is cancelled in the following situations:

  • The accelerator pedal is pressed over a certain level.

  • The vehicle stops.

  • ESC (Electronic Stability Control) or other electronic devices have malfunctioned.

  • In a situation system cannot operate normally.

  • 10 seconds have passed since the brake has been controlled automatically by Multi-Collision Brake system.

  • Multi-Collision Brake decreases vehicle speed after a collision and reduces the risk of a second collision, but it does not prevent a second collision. You may drive away from the collision spot to avoid other dangerous situations by pressing the accelerator pedal.

  • After the vehicle is stopped by Multi-Collision Brake, the system stops controlling the brakes. Depending on the situation, the driver should press the brake or the accelerator pedal to prevent further accidents.
