Embodiment Construction
[0057] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0058] Explanation of abbreviations:
[0059] Handbrake—whether the vehicle handbrake is pulled up;
[0060] Pneumatic braking--Pneumatic braking system participates in braking;
[0061] Electric braking--regenerative braking in which the drive motor participates;
[0062] Minimum speed range--at low speeds, the recovery efficiency of the motor is low, and the recovery power is small, and the braking of the electric brake dining chair is likely to cause braking impact, which affects the smoothness of the brakes, so set a threshold value of the speed range , greater than the maximum value of the interval threshold, the motor fully participates; less than the minimum value of the interval threshold, the motor completely exits; between the interval thresholds, the motor partially par...
