Parking Brake Status

Status of the parking brake.

Mandatory

Not priority – move to step 2

Justification:

Parking brake signal has certain value for judging whether the vehicle is affected by parking brake force in accident (especially the vehicle equipped with independent parking brake device). In accident reconstruction, whether the parking brake is working or not will have obvious differences for analyzing the vehicle trajectory. For example, the vehicle was in a stopped state, and it was hit by a rear-end vehicle. The front car slipped out by impact. It is necessary to consider whether the parking brake of the front car was in working state when calculating the speed of the rear car according to the distance. It has obvious influence on the speed of the rear car obtained in analysis.
