According to the driving motor system and the fault protection method thereof provided by the invention, under the condition that a driving motor has a fault and needs to be shut down, the motor needs to be freely shut down or a three-phase line needs to be short-circuited according to the rotating speed of the motor. When the rotating speed of the motor is smaller than the set value, the motor cannot output large braking torque, large braking deceleration cannot be generated, at the moment, the motor controller controls the motor to stop freely, the risk that a driver and passengers incline forwards does not exist, and safety is achieved. And meanwhile, when the rotating speed is small, the torque is not too large, so that large back electromotive force is not generated, the current value of three-phase current generated by the back electromotive force fed back to direct current through rectification is small, and the direct current is fed back to the power battery without causing overcharge ...

The invention relates to a charging method for hybrid electric bus super capacitors. A super capacitor is charged by a generator carried by a hybrid electric bus. First, the super capacitor is charged at limited power through counter electromotive force generated by the generator; when the voltage of the super capacitor reaches a first set value through charging, an engine is started to drive the generator to charge the super capacitor at low power; when the voltage of the super capacitor reaches a second set value, power is compensated to the super capacitor through trickle charge; and when the super capacitor is compensated to reach a certain range, the speed of the engine is improved to an economic zone, and the generator is driven by the engine to charge the super capacitor at high power. The whole charging process requires no external charger or new equipment. The charging process is simpler. The defects of a scheme in which a super capacitor and a motor are combined are avoided. The ...

The invention relates to a pedal type recognition method and a vehicle, after a pedal of a new energy vehicle is replaced and the whole vehicle is powered on at low voltage, a whole vehicle controller recognizes the pedal type of the corresponding pedal and sends the pedal type to a motor controller. Pedal configurations corresponding to different types of pedals are stored in the motor controller, and after the motor controller obtains the pedal type from the vehicle control unit, the corresponding pedal configuration is selected according to the pre-stored corresponding relation between the pedal type and the pedal configuration and the pedal type. The pedals are configured to have voltage values corresponding to switching value signals output by different types of pedals. Therefore, after the pedal configuration corresponding to the currently installed pedal is selected, the motor controller is set to be the pedal configuration, so that the motor controller can accurately identify the ...

The invention relates to a three-phase full-bridge switch circuit fault detection method and device. The method in the invention needs to detect a single bridge arm of some phase respectively. At the beginning of the detection, a switch circuit works in the state that the bridge arm at one side of the phase is connected and the bridge arms at the opposite sides of the other two phases are connected; and then, the current of the phase is detected, and whether faults occur and what kinds of faults they are can be judged according to the current value of the phase. The method can judge IGBT fault without disassembling a controller, thereby saving time and saving energy, and improving efficiency.
