The invention belongs to the vehicle control unit field. The vehicle control unit comprises a central processor; the central processor is connected with a power source module, an analog quantity acquisition module, a switching quantity acquisition module, a frequency quantity acquisition module, a low-end driving module, a motor control module, a motor current-detection module and a CAN communication module through signal lines respectively. According to the vehicle control unit, acquired signals are processed through the analog quantity acquisition module, the switching quantity acquisition module and the frequency quantity acquisition module; processed signals are transmitted to the central processor; the central processor communicates with a vehicle CAN communication module through the CAN communication module; the electric loads of relays work according to requirements under the control of the central processor; the motor control module can realize gear selection and gear shift under the control of the central processor; and therefore, the vehicle control unit can obtain the running state of a vehicle at any time in a driving process and accurately acquire the operating information of a driver, and analyzes the operating conditions of various components of the vehicle, so as to coordinate the actions of various mechanisms. The vehicle control unit has the advantages of simple structure, safety and reliability, and can assist in reducing cost.
