The invention relates to a drive circuit for a vehicle-mounted steering wheel. The drive circuit comprises a switch panel, a power supply unit, an acquisition unit, a single-chip microcomputer unit and a drive unit, wherein the single-chip microcomputer unit is simultaneously connected with the power supply unit, the driving unit and the acquisition unit through cables, and the switch panel is connected with the acquisition unit through a cable; the switch panel is fixed on the steering wheel through the switch panel; the power supply unit converts 24 V of a vehicle into 5 V and provides stable electric energy for the single-chip microcomputer unit; the acquisition unit acquires a switching signal and a driving state signal of the switch panel; the output of the driving unit is controlled,and an indicator light of the switch panel is driven to work; the single-chip microcomputer unit collects a driving state signal through the driving unit and executes a driving short-circuit overcurrent protection strategy and an anti-empty lamp control strategy according to the collected signal. The drive circuit is advantaged in that a technical problem of combining a steering wheel switch panel and a steering wheel driving box into a whole is solved, the service life is long, and an air defense lamp control strategy and an intelligent protection strategy can be executed.

    本发明涉及一种车载方向盘用驱动电路。该驱动电路包括开关面板、供电单元、采集单元、单片机单元和驱动单元;单片机单元通过线缆同时与供电单元、驱动单元和采集单元连接,开关面板通过线缆与采集单元连接;开关面板通过开关面板固定在方向盘上;供电单元将车辆的24V变为5V,为单片机单元提供稳定电能;采集单元采集开关面板的开关信号和驱动状态信号;控制驱动单元的输出,同时驱动开关面板的指示灯工作;单片机单元通过驱动单元采集驱动状态信号,并根据采集信号执行驱动短路过流保护策略和防空灯控制策略。本发明解决了将方向盘开关面板与方向盘驱动盒合二为一的技术问题,具有使用寿命长,能执行防空灯控制策略和智能保护策略。
