The invention discloses a circuit for judging the abnormality of vehicle throttle states, and electronic equipment with the circuit. The circuit for judging the abnormality of vehicle throttle states comprises a sampling module, a digit-analog calibrating module, a reset module, a key module, a linkage module and a main control module, wherein the sampling module is used for sampling a power-on voltage, namely the voltage of a sliding variable-resistance module connected with a mechanical device of a vehicle throttle; the digit-analog calibrating module is used for performing automatic voltage calibration according to the indication of the main control module; the rest module is used for performing reset after the main control module is powered on; the key module is used for controlling the linkage module to stop working through the main control module; the linkage module is used for starting braking operation according to the indication of the man control module; the main control module is used for indicating the digit-analog calibrating module to perform automatic voltage calibration according to the power-on voltage sampled by the sampling module, and for judging whether to start the linkage module or not according to the voltage value sampled by the sampling module, of the sliding variable-resistance module connected with the mechanical device of the vehicle throttle. Through the adoption of the circuit disclosed by the invention, the design cost can be reduced, and the control complexity can be reduced.
