Description

technical field

[0001] The invention relates to a brake pedal stroke measurement technology, in particular to a vehicle brake pedal stroke measurement device and a measurement method thereof. technical background

[0002] In the field of automobile testing, it is usually necessary to record the driver's use of the brake pedal, such as the frequency of the driver's use of the brake pedal and the severity of the brake pedal. Whether the brake pedal is used or not and the weight of the pedal directly reflects the driver's operating conditions on the vehicle. It is a parameter that needs to be accurately recorded during the car test. This parameter can accurately reflect the driver's driving during the car test. Operating behavior, combined with vehicle and road environment parameters, can reflect the driver’s driving behavior characteristics, and truly reflect the interaction between the driver, vehicle, and road. Therefore, it is usually necessary to use relevant measurements ...
