The invention relates to a method and system for monitoring a steering wheel holding posture of a driver. The method comprises the steps that S1, an image of the hand posture of the driver in a steering wheel rim area is collected; s2, if the hands of the driver leave the steering wheel and the time for continuously leaving the steering wheel exceeds a first preset time, giving an alarm; s3, if other parts except the hands of the driver are in contact with the steering wheel and the continuous contact time of the steering wheel exceeds a second preset time, giving an alarm; s4, collecting an intensity change value of a capacitance signal on the steering wheel; and S5, if the intensity change value of the capacitance signal on the steering wheel does not exceed the preset threshold value and the duration of the intensity change value does not exceed the preset threshold value exceeds a third preset time, giving an alarm and continuing to execute S4, otherwise, returning to S1. According to the invention, the accuracy and reliability of monitoring are improved, the driving risk is reduced, the driving safety performance is improved, and the requirement of automatic driving technology is met.
本发明涉及一种监测驾驶员持握方向盘姿态的方法及系统,所述方法为:S1:采集方向盘轮圈区域驾驶员手姿态的图像;S2:若驾驶员的手离开方向盘,且持续离开方向盘时间超过第一预设时间,则发出警报;S3:若除驾驶员手部外存在其他部位接触方向盘,并且持续接触方向盘时间超过第二预设时间,则发出警报;S4:采集方向盘上电容信号的强度变化值;S5:若方向盘上电容信号的强度变化值未超过预设阀值,且未超过预设阀值的持续时间超过第三预设时间,则发出警报,并持续进行S4,否则回到S1。本发明提高了监测的精准度和可靠性,降低行车风险,提高驾驶安全性能,推动满足自动驾驶技术的需求。
