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 depression intensity of 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 (112 mph) at the time of collision.

    • The brake pedal and accelerator pedal are hardly depressed.

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

System off

  • Multi-Collision Brake is cancelled in the following situations:

    • The accelerator pedal is depressed over a certain level.

    • The vehicle stops.

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

    • In a situation system cannot operate normally.

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

WARNING

  • 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 depressing 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 depress the brake or the accelerator pedal to prevent further accidents.
