Powertrain diversification is on the rise. While there used to be little else than diesel and gasoline engines in the past, now powertrain solutions include all degrees of electrification. The centralized Powertrain Controller is the solution for the fact that functions and software are getting more complex and that interconnected functions require lots of processing power.

Versatile
Can handle the growing variant diversity and complexity in vehicles

Powerful
Makes processing power available with high-performance microcontrollers

Powerful in diverse applications
As a powertrain domain controller, the vehicle control unit can provide torque coordination, operation and gearshift strategies, high-voltage and 48V coordination, charging control, on board diagnosis, monitoring, thermal management, charge communication and much more for electrified and connected powertrains.

The vehicle control unit can be used in electrified passenger cars, trucks and Off-Highway vehicles but also in combustion engines applications.

The vehicle control unit also ensures fail-operational function for highly automated driving solutions.

Simple integration of new functions
The vehicle control unit coordinates the components in the powertrain or even assumes some of their functions. This includes control of the inverter and battery management system as well as transmission and engine control. Battery charging control (communication with the charging station via a standardized interface) can be integrated in the vehicle control unit as well.

In addition, the introduction of a new level of abstraction in the E/E architecture makes variant handling of changing powertrain components much easier and saves resources in the subsidiary component-related control units. Due to its modular and configurable hardware and software, the vehicle control unit can be flexibly designed to meet future requirements.

The vehicle control unit standard is available in two standard versions – vehicle control unit standard mid and vehicle control unit standard max – and is scalable to fit customer demands. It uses resource-optimized classic micro-controller technology based on the latest engine management generation.

Vehicle Controller VCU is the core control component of vehicle. With energy management, torque coordination and distribution, Motor Battery Coordination Management, safety monitoring, UDS fault diagnosis, braking energy recovery and other functions. The function and performance of VCU determines the driving, power, safety and economy of the whole vehicle.

The vehicle controller functions somewhat like the engine control unit of a fuel-powered vehicle. It is the “Brain” of the new energy vehicle control system, by collecting the signals of the power on the vehicle, the acceleration pedal, the brake pedal, the shift signal, the motor module, the controller, the actuator, the sensor and so on, based on the driving state of the vehicle and the intention of the driver, a comprehensive analysis is made and the corresponding decision is made, then the control signal is output to each lower part controller to control the electric vehicle to enter different operating modes, and display the key information in the vehicle instrument and the big screen.

The function of VCU vehicle controller is to collect various signals. VCU (Vehicle control unit) , as the central control unit of new energy Vehicle, is the core of the whole control system. The VCU collects the status of the motor and the battery, the acceleration pedal signal, the brake pedal signal, the actuator and the sensor signal, and makes the corresponding judgment according to the driver's intention comprehensive analysis, monitor the actions of the lower level component controllers. It is responsible for the normal running of the vehicle, braking energy feedback, the whole vehicle drive system and Power Battery Energy Management, network management, fault diagnosis and treatment, vehicle status monitoring, etc. , so as to ensure the vehicle in a better power, high economy and reliability of the normal and stable working state. It can be said that the performance of the vehicle controller directly determines the performance of the new energy vehicle, played a mainstay role.

VCU control function introduction

1. According to the driver's requirements, vehicle status, and other working conditions, reasonable control of motor working state and power output, to meet the driving conditions. Including acceleration and deceleration, constant speed, braking and backward working conditions.

2. Brake energy feedback control judge brake mode, calculate brake torque distribution and recover part of energy according to brake pedal and acceleration pedal information, vehicle running information and power battery loading status information.

 3. Vehicle energy optimization through the coordination of Electric Vehicle Motor Drive system, battery management system, transmission system and other vehicle energy-consuming components and the tube to change the light, to obtain the best energy utilization ratio, extended use.
