The invention relates to the technical field of vehicle braking, and discloses a proportional electromagnetic valve, a braking system, a vehicle and a proportional electromagnetic valve control method. The electromagnetic mechanism is embedded in the valve body; the valve body is provided with an air inlet and a pressure space; the pressure space is arranged on the side, facing the valve body, of the electromagnetic mechanism. The electromagnetic mechanism comprises a valve rod and an electromagnetic assembly. The electromagnetic assembly can push the valve rod to move towards the pressure space. An abutting part is formed on the valve rod, and the abutting part can be formed by connecting sealing rubber and the valve rod; when the abutting part abuts against the valve body, the abutting part is used for sealing the air inlet; when the valve rod moves towards the pressure space, the abutting part is separated from the valve body, and gas enters the pressure space; according to the invention, one electromagnetic mechanism is controlled through the CAN bus, so that the pressure of the brake pipeline can be adjusted, the control difficulty is reduced, and the brake efficiency is improved; in addition, follow-up balance of the proportional electromagnetic valve can be achieved through the action of air pressure on the valve rod, and the driving experience of a driver is improved.

    本发明涉及车辆制动技术领域,公开了一种比例电磁阀、制动系统、车辆及比例电磁阀控制方法,设置有阀体、电磁机构和CAN总线;电磁机构嵌设在阀体内;阀体设置有进气口和压力空间;压力空间设置与电磁机构朝向阀体一侧;电磁机构包括阀杆和电磁组件,电磁组件能够推动阀杆朝向压力空间运动;阀杆形成有抵接部,抵接部可以有密封橡胶与阀杆连接形成;抵接部与阀体抵接时,抵接部用于封闭进气口;阀杆朝向压力空间运动时,抵接部与阀体分离,气体进入压力空间;本发明通过CAN总线控制一个电磁机构,即可实现对制动管路的压力的调节,降低了控制难度,提高制动效率;并且可以通过气压对阀杆的作用,实现比例电磁阀的随动平衡,提高驾驶者的驾驶体验。
