description The invention provides a vehicle protection circuit and system and a vehicle. The vehicle protection circuit is characterized in that a first input end of an operational amplifier is connected with one end of a controlled circuit, and a second input end of the operational amplifier is connected with the other end of the controlled circuit; the base of the first triode is connected with the output end of the operational amplifier, and the collector of the first triode is connected with the input end of the control circuit; when the controlled circuit is in an abnormal state, the first input end of the operational amplifier is used for collecting the reverse electromotive force of the controlled circuit and outputting an enable signal based on the reverse electromotive force, and the enable signal enables the control circuit to stop working; therefore, when the controlled circuit is abnormal, the vehicle protection circuit can interfere with the control circuit in time, so that the control circuit stops working
