Beschreibung
Zusammenfassung:	The utility model discloses an electromagnetic valve driving circuit for a vehicle. A vehicle-mounted battery VBAT is connected with an electromagnetic valve follow current module after sequentially passing through an anti-reverse module and a high-side electromagnetic valve power supply module, an electromagnetic valve coil is connected to the electromagnetic valve follow current module, a low-side grounding switch module is led out between the anti-reverse module and the high-side electromagnetic valve power supply module, and the high-side electromagnetic valve power supply module is connected to a driving port of an MCU. The electromagnetic valve follow current module is connected to a PWM driving signal port of the MCU through the low-side grounding switch module, the electromagnetic valve follow current module is connected to an analog-to-digital conversion port of the MCU through the electromagnetic valve current acquisition module, and the electromagnetic valve follow current module is connected to a
