The invention relates to a steering wheel electric heating control method and system. The method comprises the steps that a heating switch is turned on; heating for a specific time; heating is stopped, the environment temperature is read, and a temperature control judgment link is entered; judging whether heating is stopped or not, and setting a heating closing threshold value; and looking up a table to select a temperature control heating threshold according to the environment temperature. The heating performance of the steering wheel is obtained only through a heating performance groping test at different environment temperatures; the temperature control heating threshold value can be found by manually simulating the on/off temperature control action; a real vehicle is subjected to system testing at different environment temperatures, and numerical values are optimized and calibrated, so that the same steering wheel heating target temperature is achieved; electrifying and heating, and reading an NTC resistance value; and judging whether a temperature control threshold value under the current environment temperature is reached or not. According to the control method, one-gear heating control and multi-gear heating control can be achieved, and the control method is applicable and high in expansibility; the control logic is simple, easy to implement, low in development difficulty, short in period, high in efficiency and low in cost; and the requirement of independent development can be met.

    本发明涉及一种方向盘电加热的控制方法及系统,方法包括加热开关开启;加热特定时长;停止加热,读取环境温度,进入判定温控环节;判定是否停止加热,设定关闭加热阈值;根据环境温度,查表选定控温加热阈值。先在不同环境温度下,仅对方向盘进行加热性能摸底测试得到;可通过手工模拟通/断控温动作,找到控温加热阈值;通过实车在不同环境温度下,进行系统测试,对数值进行优化标定,以达到相同的方向盘加热目标温度;通电加热,并读取NTC阻值;判定是否达到当前环境温度下的控温阈值。本发明控制方法可实现一档加热、多档加热控制,都适用,扩展性强;控制逻辑简单,易于实现,开发难度低、周期短、效率高、成本低;可满足自主开发的需求。
