How the ECU works

  1. The assist motor current needed is calculated, in accordance with thedriver’s steeringoperation yorque and the vehicle’s speed.

  2. The PWM ratio is calculated based on the actuai motor current, and thenthe motor is driven to provide steering assist force.

  3. Self-diagnosis is performed to ensure safety and reliability based onthe various sensors’ signal.

  Features

  1. Selection of automotive level MCU to adapt any badly environments.

  2. EMC design to achieve good EMC characteristic.

  3. Redundancy fails safe design of ECU’s software and hardware to ensure safety and reliability.

 4. Fuii product type design to perform matching and debugging easily.
