The invention discloses an electromagnetic valve control circuit and method, a braking system and a vehicle. The electromagnetic valve control circuit comprises a control module, a first switch module, a second switch module and an electromagnetic valve. The control module is electrically connected with the first switch module and is used for outputting a PWM control signal to the first switch module; the first switch module is electrically connected with the second switch module and is used for being turned on and turned off under the control of the PWM control signal; the second switch module is electrically connected with a coil of the electromagnetic valve and used for transmitting electric energy output by the power supply to the coil of the electromagnetic valve when the first switch module is started so as to drive the electromagnetic valve to work. According to the electromagnetic valve control circuit and method, the braking system and the vehicle, the cost can be saved, and the control frequency can be improved.
