The invention discloses a control and protection self-checking circuit of a vehicle electromagnetic valve, comprising a single chip microcomputer and an electromagnetic valve, wherein the single chip microcomputer is provided with two control ends and two feedback ends, the higher edge control end is communicated with a higher edge connector through a higher edge control circuit, the lower edge control end is communicated with a lower edge connector through a lower edge control circuit, the electromagnetic valve is installed between the higher edge connector and the lower edge connector, a power diode is connected between the higher edge connector and the lower edge connector in a crossing way, a cathode of the power diode is connected with the higher edge connector, an anode of the powerdiode is connected with the lower edge connector, and a higher edge feedback end and a lower edge feedback end are respectively communicated with the higher edge connector and the lower edge connector through a higher edge feedback circuit and a lower edge feedback circuit. The invention rapidly eliminates back electromotive force of the electromagnetic valve through the power diode which is connected in parallel with the electromagnetic valve, ensures that other components are not impacted, judges whether a working state of the electromagnetic valve and a control switch of the electromagnetic valve are normal or not through voltage values of two paths of control signals and two paths of feedback signals and tracks a concrete work state of the electromagnetic valve, thereby greatly lowering the risk of system failure.
