The invention discloses a double-brake-switch braking system for an electric forklift and a fault detection method thereof.The double-brake-switch braking system for the electric forklift comprises a brake pedal mechanism, a first brake switch, a second brake switch, a VCU controller, an instrument and a brake signal lamp, and a trigger point, for obtaining a brake pedal signal in the brake pedal mechanism, of the first brake switch is arranged at the initial position of a brake pedal; and a trigger point for acquiring a brake pedal signal in the brake pedal mechanism by the brake switch II is arranged at a preset position in the travel of the brake pedal and is different from the signal trigger point of the brake switch I in position. By arranging the two brake switches, it can be ensured that when one brake switch is damaged, the whole vehicle can be effectively braked, safety is ensured, the working states of the two brake switches are judged according to brake deceleration rate signals fed back by the motor by means of different trigger positions of the two brake switches, maintenance personnel can conveniently judge the fault type and position, and the safety is improved. And rapid maintenance is carried out.

    本发明公开了一种电动叉车用双制动开关制动系统及其故障检测方法,包括制动踏板机构、制动开关一、制动开关二、VCU控制器、仪表和制动信号灯,制动开关一获取制动踏板机构中制动踏板信号的触发点设置在制动踏板处于初始位置处,制动开关二获取制动踏板机构中制动踏板信号的触发点设置在制动踏板行程中的预设位置处且与制动开关一的信号触发点位置不同。本发明通过设置有两组制动开关,可以确保在一个制动开关损坏时,整车实现有效的制动,确保安全,并且利用两组制动开关触发位置不同,根据电机反馈的制动减速率信号判断两组制动开关的工作状态,便于维护人员判断故障类型和位置,进行快速检修。
