The invention provides a vehicle steering wheel off-hand detection system, which comprises a capacitance sensor and a processor. The capacitance sensor acquires a steering wheel induction capacitancevalue and a circuit parasitic capacitance value and transmit the induction capacitance value and parasitic capacitance value to the processor. The processor calculates an off-hand detection value according to the induction capacitance value and parasitic capacitance value and controls an early warning system to send out an early warning prompt if the off-hand detection value is determined to be smaller than the preset value. The off-hand detection value is calculated according to the induction capacitance value and the parasitic capacitance value, the off-hand detection value is jointly determined by the induction capacitance and the parasitic capacitance, the technical problem of inaccurate detection caused by pure detection of the induction capacitance is avoided, and the reliability andaccuracy of off-hand detection are improved.

    本申请提出了一种车辆方向盘离手检测系统,检测系统包括:电容传感器,电容传感器获取方向盘感应电容值、电路寄生电容值,并将感应电容值和寄生电容值传输到处理器,处理器,处理器根据感应电容值和寄生电容值,计算离手检测值,确认离手检测值小于预设值,则控制预警系统发出预警提示。根据感应电容值和寄生电容值计算离手检测值,离手检测值由感应电容和寄生电容共同决定,避免单纯检测感应电容造成检测不精确的技术问题,提高离手检测的可靠性与精准性。
