The invention discloses a motor torque limiting method and device, a medium and electronic equipment. The method comprises the steps that a first torque limiting condition, a first torque threshold value, a second torque limiting condition, a third torque limiting condition, a second torque threshold value and vehicle parameters are obtained; according to the first torque limiting condition and the vehicle parameters, a first torque limiting value is obtained; obtaining a second torque limiting value according to a second torque limiting condition and the vehicle parameters; according to the third torque limiting condition and the vehicle parameters, a third torque limiting value is obtained; according to the first torque limiting value, the second torque limiting value and the third torque limiting value, the minimum value of the first torque limiting value, the second torque limiting value and the third torque limiting value is obtained; and limiting the motor torque below the minimum value of the first torque limit value, the second torque limit value and the third torque limit value. According to the application, the motor torque is limited by judging the abnormal state of the EPB, so that the large-torque locked-rotor damage of the motor is avoided.
