Abstract

The invention relates to a portable dragging moment measuring device and method based on PID control. The problem that in the prior art, the vehicle dragging moment cannot be accurately measured underthe whole vehicle state is mainly solved. The portable dragging moment measuring device comprises a torque measuring device, a motor arranged on the torque measuring device, an adjustable mounting mechanism arranged on the motor, a first adjustable mounting frame connected with the torque measuring device, an adjustable length locking pin connected with the first adjustable mounting frame, and aPID controller for controlling the motor to rotate at a constant rotating speed. The PID controller is in circuit connection with the motor. The vehicle dragging moment can be accurately measured under the whole vehicle state, adverse influences of repeated dismounting and mounting on a vehicle are avoided, and thus the measuring process is easier, more convenient and more accurate.

Description

technical field [0001] The invention relates to the field of detection devices for vehicle parts, in particular to a portable drag torque measurement device and method based on PID control. Background technique [0002] The traditional braking system adopts the mode of brake pedal, booster master cylinder, brake oil pipe and wheel brake. The driver manipulates the brake pedal, and after being assisted by the booster, the oil pressure is established in the brake master cylinder, and the brake oil pipe transmits the oil pressure to the wheel brake to realize braking. Conventional brakes now include disc brakes and drum brakes. When the driver releases the brake, the brake pedal is relaxed, but the wheel brakes are still fully or partially in the braking state, and the brake cannot be released quickly, which will cause the brake drum (disc) to heat up and the driving resistance to increase. The most commonly used method is bench measurement. The existing brake drag torque me...
