Braking distance

Braking distance. The braking distance is the distance traveled by the vehicle from the moment the driver notices the obstacle until the moment the vehicle stops. Time, in which the vehicle travels the braking distance, is the sum of three characteristic periods: driver reaction, actuating the brakes, proper braking. The driver's reaction is the period from the moment of noticing an obstacle or danger to the moment of pressing the brake pedal. During this period, the driver recognizes the danger, decides and reacts by pressing the brake pedal with his right foot. The response time is not constant and, depending on the individual characteristics of the driver, is 0.5-l s. Applying the brakes is the time from the moment the pressure is applied to the brake pedal until the brakes are fully applied. During this period, the pressure of the driver's foot on the pedal eliminates all play in the braking system and overcomes the resistance of applying the brakes. The brake application time is normally 0,15-0,5 s.
