Hybrid Control Unit

Hybrid Control & Electronic designed for automotive environment

  • Robust design are achieved through Ricardo analysis capabilities and expertise
  • Control and Electronic components can be manufacturer by our partner Delta Electronic  to Ricardo specifications
  • Combining their respective strengths, the Ricardo-Delta alliance will provide total solutions and a single point of contact for customers to purchase new modules and systems. Automakers will benefit from the independent R&D expertise and associated intellectual property (IP) protection of Ricardo and the superior quality and efficiency of world-class electronics manufacturer Delta Electronics

Control System and Safety Design

  • Hybrid Control Unit (HCU) development projects include:
    • Function control development for Micro, Mild and Full hybrid applications
    • Supervisory control
    • Safety/sensor interlock strategy and implementation
    • Calibration/diagnostics interface support
  • Integration of hybrid functionality into donor EMS
  • Design and development of HCU hardware and software
  • Hybrid control system include the following features
    • CAN communication with DC-DC converter, BMDU, B-ISG controller
    • Additional sensors and actuators for hybrid function
    • Partial-state-of-charge control
      • Necessary to allow regenerative braking
      • Ricardo proprietary Cost Function based algorithm
    • Stall protection feature
      • B-ISG positive torque supplied if a stall is detecte

Benefits of integrated hybrid control unit

  • Single case for three units, minimising tooling and development costs
  • Single external connection system for the three units, minimizing harness and connector costs and simplifying routing and vehicle assembly
  • Single cooling jacket for the Inverter and DC Converter, minimizing the cost and assembly of the cooling circuit
  • Single installation required for the three units, minimizing bracket costs and assembly
