Description

technical field [0001] The invention belongs to the technical field of auto parts testing equipment, and in particular relates to a dynamic braking performance testing device for testing an integrated electronic parking brake system. Background technique [0002] The traditional parking brake needs to cooperate with more skilled accelerator pedal and clutch operation to start smoothly when starting on a slope. Foreign auto companies have turned their attention to the electronic parking brake system EPB (Electronic Park Brake), which is easier and more reliable to operate. It combines emergency braking at low speeds with hill start assist systems, and is one of the new development directions for active safety components in modern vehicles. Since the dynamic function of EPB is quite different from that of the traditional parking system, and the cost of on-board testing is high and the risk factor is also high, domestic research needs to obtain the dynamic braking performance o...
