The invention relates to an electromagnetic valve drive control circuit and method and a vehicle. The circuit comprises a first branch, a second branch and an electromagnetic valve. The first branch circuit and the second branch circuit are connected between the first power supply end and the second power supply end, and potential difference exists between the first power supply end and the second power supply end; the first branch comprises a first anti-reverse element and a first controlled switch element which are connected in series, and the second branch comprises a second anti-reverse element and a second controlled switch element which are connected in series; one end of the electromagnetic valve is connected between the first anti-reverse element and the first controlled switch element, and the other end of the electromagnetic valve is connected between the second anti-reverse element and the second controlled switch element; wherein the second controlled switch element is used for controlling the current decay speed by controlling the switching time proportion of the second controlled switch element in the current decay stage. The number of the controlled switch elements is two, the application cost of the circuit is reduced, the anti-reverse element is arranged, and the problem of current reverse is solved based on the one-way conduction characteristic of the anti-reverse element.

    本公开涉及一种电磁阀驱动控制电路、方法及车辆,该电路包括:第一支路、第二支路和电磁阀;第一支路和第二支路均连接在第一电源端和第二电源端之间,第一电源端和第二电源端之间存在电势差;第一支路包括串联的第一防反元件和第一受控开关元件,第二支路包括串联的第二防反元件和第二受控开关元件;电磁阀的一端连接在第一防反元件和第一受控开关元件之间,电磁阀的另一端连接在第二防反元件和第二受控开关元件之间;其中,第二受控开关元件用于在电流衰减阶段通过控制第二受控开关元件的开关时间比例以控制电流衰减速度。本公开中受控开关元件的数量为两个,降低了电路的应用成本,及设置防反元件,基于其单向导通的特性,克服电流反向的问题。
