Electric vehicles rely on the electric energy provided by the power battery pack as the power source to drive the motor to rotate, thereby providing power for the entire vehicle. The structure of a pure electric vehicle mainly includes a motor drive system, an energy management system, a vehicle control unit, a charging control unit, a power conversion device DC/DC, and an instrument display system.
Vehicle Control Unit (Vehicle Control Unit VCU), also known as vehicle control unit, is the core electronic control unit that realizes vehicle control decisions. It is now widely used in pure electric vehicles and hybrid vehicles. The VCU is equivalent to the brain of the entire vehicle and plays an important role in the scheduling of various functions and systems. The realization of its functional safety plays a vital role in the safety of the entire vehicle.
Basic functions of VCU
VCU is the core electronic control unit that realizes the control decision of the whole vehicle, and the demand in traditional cars is small. The development of vehicle controller includes software and hardware design. The core software is generally developed by the vehicle manufacturer, and the hardware and underlying driver software can optionally be provided by the auto parts manufacturer.
The VCU collects motor control system signals, accelerator pedal signals, brake pedal signals, and other component signals, and after comprehensive analysis and response judgments based on the driver’s driving intentions, it monitors the actions of the lower component controllers and controls the normal driving of the car. Functions such as battery energy braking feedback, network management, fault diagnosis and processing, and vehicle status monitoring play a key role.
