Background
The temperature control of the heating function of the mainstream steering wheel in the current market belongs to passive control, and a controller ensures that the surface temperature of the steering wheel meets the temperature rise curve range required by a drawing by controlling the on-off time (duty ratio) of working current. The whole control process is that full power is firstly heated, a temperature sensor arranged under the wheel rim of the steering wheel is covered, after the highest temperature is identified, the heat preservation stage is started, and the heat preservation control is carried out by controlling the duty ratio of the working current.

Considering influences such as surrounding environments (heat dissipation or insolation of the driver side glass and the windshield, cold or hot air blowing from an air-conditioning duct to a steering wheel, air leakage from a driver side door, etc.); influence of the design of the steering wheel (the rim of the steering wheel is generally divided into three to four areas, the switch and the decoration of the steering wheel are generally arranged at 3 o ' clock, 6 o ' clock and 9 o ' clock, the arrangement areas of the heating pads of all the areas are different, and the heat dissipation conditions are different due to the overlapping of the heating pads and the periphery parts); the individual areas adopt the design of punching skins, and the heat dissipation speed is different from that of non-punching skins. The above influence factors cause the problem of uneven heating of the steering wheel to be more obvious.
If the problem that the steering wheel is heated unevenly is continuously solved by the technology, the interval distance (density arrangement between the heating wires) of the heating wires in different areas of the steering wheel needs to be changed, namely, the heating wires in the areas with low temperature are subjected to encryption arrangement design, so that the non-universal design of the heating pad is brought, and the comprehensive cost is not reasonable. Therefore, the technology cannot achieve optimal design between cost and performance, or the problem of uneven heating is tolerated by considering the cost; or the problem of uneven heating is solved without considering the cost.
