    The Vehicle Control Unit, or VCU, is the supervisory controller for electric or hybrid vehicles.

    Ecotron offers the low cost but high performance VCUs based on NXP micros, like MPC5744ASIL-D rated, and also another powerful VCU based on Infineon TriCore TC297micro, ASIL-D rated, too.

    Ecotron VCUs are future oriented. The standard VCU comes with 3+ CAN bus. High performance VCUs come with FlexRay and optional Ethernet functions. All VCUs are capable of OTA (Over-The-Air) programming.


    • Ecotron VCU is designed with ISO26262 functional safety in mind, and comes with a main chip and a monitor chip built-in, for safety monitoring
    • Ecotron 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
    • Ecotron VCU comes with a CAN bus based reprogramming tool, and with properly configured protocols, it can be used for OTA programming
    • Ecotron VCU supports the CCP/XCP based CAN bus calibration tools, like INCA, CANape, as well as the cost effective EcoCAL, developed in-house


    • Electric cars
    • Electric trucks
    • Electric bus, commercial vehicles
