VCU- Vehicle Control Unit


The Vehicle Control Unit, or VCU, is the core controller for electric vehicles. The VCU receives the driver input signals such as pedal inputs and vehicle speeds and uses these signals to manage the system energy, command the torque, and coordinate the motor, battery pack and the on- board charging system. All of these factors determine the overall vehicle drivability.

The VCU is the master of the vehicle control network, or CAN bus based vehicle control network.



  • Ecotrons VCU is designed with ISO26262 functional safety in mind, and comes with a main chip and a monitor chip built-in, for safety monitoring.
  • Ecotrons VCU comes with the basic software, or BSW, support all typical input / output drivers for vehicle controls. The BSW is encapsulated in the Matlab/Simulink environment, and the user can develop the control system with 100% model based design methods.
  • The VCU hardware is abstracted from the application software and relieves the controls engineer from the challenge of the microprocessor configuration and embedded real-time software.
  • Ecotrons VCU comes with a CAN bus based reprogramming tool, supported by the bootloader pre-programmed into the microprocessor.
  • Ecotrons VCU supports the CCP/XCP based CAN bus calibration tools, like INCA, CANape, as well as the cost effective EcoCAL, developed by Ecotrons.
