Vehicle control unit integrated with TCU gear shifting motor control circuit

Abstract

The invention relates to a vehicle control unit integrated with a TCU gear shifting motor control circuit, which is characterized in that a sensor power supply circuit unit supplies power to a sensor unit, and the sensor unit acquires the current gear position of a gear shifting motor and the rotating speed of a gearbox gear in real time and outputs a corresponding voltage sensing signal; the microprocessor unit acquires a voltage sensing signal through the sensor signal acquisition circuit unit; when the microprocessor unit judges that gear shifting is needed, the microprocessor unit controls connection and disconnection of an MOS tube in the motor drive circuit unit through the MOS tube pre-drive circuit unit according to the voltage sensing signal, the motor drive circuit unit drives the gear shifting motor, gear selection and gear advancing and retreating are conducted, and the gear shifting function of the gearbox is achieved. The vehicle control unit is integrated with the TCU function, and the integrated vehicle control unit is used for controlling the whole vehicle and the gear shifting mechanism, so that the hardware and structure cost is reduced, the whole vehicle control logic is simplified, the logic complexity of the whole vehicle control software is reduced, and the processing speed is increased.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle controller integrating a TCU shift motor control circuit. Background technique [0002] With the improvement of customer demand and the development trend of intelligent driving, there are more and more control units in commercial vehicles, which will greatly increase the complexity of the entire system, thereby reducing the stability of the system. In addition, the complete separation of each subsystem is very difficult. It is difficult to effectively share resources, and the hardware cost and software complexity are high. Therefore, simplifying the control of the system and reducing the cost become the trend of future development. [0003] At present, the shifting mechanism of new energy commercial vehicles is modified on the gearbox of traditional fuel vehicles, and is controlled by a special control unit, that is, the Transmission Control Unit (TCU), and...
