VCU - Vehicle Control Unit

Introduction

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.

Note: VCU can also be used as HCU for hybrid vehicles, check out our HCU page here:

 

Features

  • 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

Applications

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