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.
