FAQs
The Vehicle Control Unit (VCU) is a pivotal Electronic Control Unit (ECU) within the EV Electronics Systems. Serving as the central nervous system of an Electric Vehicle, the VCU manages and coordinates various subsystems of the EV Vehicle System.
The VCU interfaces with other ECUs such as Battery Management, Motor Control Unit, Braking System, Charger System, Cluster Display, and Telematics. It’s interconnected via multiple CAN bus networks, acting as a Gateway module to facilitate signal transfer between ECUs.
Centralized Architecture: In this setup, a single central ECU oversees most vehicle functions. VCU functions are integrated with the MCU and BMS.
Decentralized Architecture: Multiple ECUs manage different functions, with each ECU interfacing with the VCU for coordination.
Domain Architecture: Also known as distributed architecture, it groups ECUs into functional domains. Here, the VCU acts as a domain controller, coordinating operations among individual ECUs within the domain.
The VCU performs various crucial functions, including:
- Wakeup Control
- Authentication
- Display Indication
- Vehicle State Management
- Riding Modes Coordination
- Powertrain Coordination
- Brake Management
- Thermal Management
- Charging Control
The VCU handles the wakeup of ECUs such as MCU and BMS based on vehicle unlock and wakeup conditions, ensuring efficient power management.
In Powertrain Coordination, the VCU provides torque coordination, throttle coordination, operation, and gearshift strategies for the Motor Control Unit (MCU), ensuring optimal performance and efficiency.
The VCU monitors the Brake system and coordinates operations between the MCU and Brake system. Additionally, it manages parameters and control for Regenerative Braking, enhancing energy efficiency.
The VCU coordinates signals over the CAN bus to assist in various riding modes, including Hill Hold Control, Adaptive Riding Position, and Traction Control, enhancing both safety and comfort during the ride.
