VCU Unique Traits Our Solution (MW and Application)
Reusing the SW common platform (standardization and Abstraction) Our Platform API abstraction is not only used by VCU Application, but it can be extended for other vehicle applications such as MCU, BMS and Telematics by utilizing the Common Reusable Platform Components such as UDS Stack, CAN Stack, XCP Stack, CAN Gateway, OTA Components etc.
Scalability The Platform API provides OS and Hardware independent API which allows Application to be developed independently by following model-based design and interface with common signal dictionary interface. New application features can be added in future without disrupting the platform modules.
Modular Architecture The architecture is modularized by having independent services designed with plug and play functionalities. New services or application components can be added based on requirements. Architecture is based on AUTOSAR or Pseudo Architecture based on customer requirement.
Configurability The architecture utilizes configurability to enable/disable specific vehicle parameters and specific features.
Safety Functional Safety Requirements are captured based on HARA analysis. HW and SW design and implementation based on Safety requirements.
Security Multiple levels of cybersecurity libraries are implemented which takes care of security with external communication, internal communication, secure boot and secure update process.

FAQs

What is a Vehicle Control Unit (VCU) in the context of Electric Vehicles (EVs)?

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.

What are the different types of EV Electronic Control Unit Architectures, and what role does the VCU play in each?

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.

What are the different types of EV Electronic Control Unit Architectures, and what role does the VCU play in each?

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.

What are some typical functionalities of the VCU in an Electric Vehicle?

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
How does the VCU manage Wakeup Control in an Electric Vehicle?

The VCU handles the wakeup of ECUs such as MCU and BMS based on vehicle unlock and wakeup conditions, ensuring efficient power management.

What role does the VCU play in Powertrain Coordination?

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.

How does the VCU contribute to Brake Management in Electric Vehicles?

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.

Can you elaborate on the VCU's role in Riding Assist features in Electric Vehicles?

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.
