Braking time
Under braking time is meant the time from the first application of the brake to stop the vehicle. The braking time includes the braking response time and the actual braking distance . The braking time depends on the driving speed and the possible braking delay .
- t = time in seconds
- v = driving speed in m / s
- a = braking deceleration in m / s²
With an assumed deceleration of 7.72 m / s² the following braking times result:
| speed | Braking time |
|---|---|
| 30 km / h | 1.08 s |
| 50 km / h | 1.80 s |
| 100 km / h | 3.60 s |
| 130 km / h | 4.68 s |
For comparison: In Formula 1 , the braking time from an initial speed of 200 km / h to a standstill is less than two seconds.
The braking time is related to the vehicle, while the human decision is made for the previous reaction path. The term braking time is often used in connection with automobiles and their safety. An attempt is the braking time by better brakes and better grip of the tires to keep as short as possible. In this way accidents can be avoided.
