We are developing a automotive ECU using PI algorithm for Heated Steering Wheel. It may be varied and complicated in the control method of Heated Steering Wheel function in the future. At start, the control of temperature is simple ON/OFF logic but temperature is hunting. It affects quality of human feeling and function of multi-step temperature control product. In order to prevent from hunting temperature, we decided to apply PI control keeping current temperature after reaching target temperature. We tested continually because PI control needs finding constant value using in software algorithm. Here are our PI control design and tested results for Heated Steering Wheel.
