The invention discloses a brake-by-wire system and a brake method for a pure electric mining dump truck. The brake-by-wire system comprises a sensor module, a control module and a brake module, the brake module comprises an electric brake, an electric eddy current brake and a hydraulic brake; in the braking process, according to an instruction of a vehicle control unit VCU, the traction motor is used as a generator, and kinetic energy of the vehicle is converted into electric energy to be stored in a battery; eddy current braking is added, so that the dumper works in cooperation with electric braking under the long downhill non-emergency braking condition, and the dumper is matched with the electric braking to conduct energy recovery. During braking, after the VCU judges that hydraulic braking needs to be implemented according to vehicle state information and braking information, the ECU controls the pressure release valve to be opened, hydraulic oil in the spring brake releases pressure, and timeliness and effectiveness of vehicle braking are achieved.

    一种纯电动矿用自卸车线控制动系统及制动方法,包括传感器模块、控制模块和制动模块;制动模块包括电制动、电涡流制动和液压制动;在制动过程中,根据整车控制器VCU的指令,牵引电机作为发电机使用,将车辆的动能转化为电能存储在电池中;电涡流制动的加入,使自卸车在长下坡非紧急制动情况下,与电制动协同工作,配合电制动进行能量回收;在制动时,整车控制器VCU通过车辆状态信息、制动信息判断需要液压制动实施后,电子控制单元ECU控制泄压阀打开,弹簧制动器中的液压油泄压,实现车辆制动的及时性和有效性。
