Skoda's Multi Collision Brake is a system that applies the brakes to prevent or mitigate a subsequent impact when a vehicle has been involved in a collision. If the airbag is fired in response to a primary collision, information is sent to the electronic stability control system to brake the vehicle. If the braking system is sufficiently intact to brake safely and effectively, the vehicle is automatically slowed down at a rate of 6ms-2 to a speed of 10km/h so that a secondary impact, for instance against another vehicle or roadside object, is avoided or at least less severe. During braking, the hazard warning lights and brake lights are illuminated and the hazard lights remain on after the braking has stopped. In the event of a serious primary collision, the driver will probably be unable to control the vehicle and Multi Collision Brake acts autonomously to reduce speed safely. Nevertheless, if the driver detects that braking after the initial impact is itself hazardous (for example, increasing the risk of being struck by following traffic), the system can be over-ridden by depressing the accelerator pedal.
