The invention provides an electric loader and an energy recovery system and method.A vehicle control unit recognizes deceleration, braking intention, deceleration, sliding and braking intensity of a driver through fuzzy logic reasoning according to displacement and speed of a brake pedal and an accelerator pedal, hydraulic braking pressure information and vehicle speed and synthesizes the deceleration, braking intention, deceleration, sliding and braking intensity of the driver into vehicle braking intensity; the braking force requirement of the whole vehicle is calculated according to the braking strength of the whole vehicle, front and rear wheel braking force distribution is carried out, electro-hydraulic braking force distribution is carried out according to the braking force requirement and the braking intention, and finally, front and rear shaft motors are controlled and adjusted to carry out regenerative braking through a PID control algorithm. The opening degrees of valve elements of the first electromagnetic proportional reversing valve and the second electromagnetic proportional reversing valve are controlled and adjusted for hydraulic braking, whole vehicle braking and energy recovery are completed, and the problem that the energy recovery efficiency of the electric loading vehicle is not high is solved.

    本发明提供了一种电动装载机、以及能量回收系统和方法,整车控制器根据制动踏板和加速踏板的位移与速度、液压制动压力信息、车速,通过模糊逻辑推理,对驾驶员减速、制动意图、减速、滑行、制动强度进行识别并合成整车制动强度,其次,根据整车制动强度计算整车制动力需求并进行前后轮制动力分配,并根据制动力需求以及制动意图进行电液制动力分配,最后,通过PID控制算法,控制和调整前后轴电机进行再生制动,控制和调整第一、第二电磁比例换向阀阀芯开度进行液压制动,完成整车制动及能量回收,解决了电动装载车能量回收效率不高的问题。
