The invention relates to a hand release detection method and device. The method comprises the following steps: acquiring a hand torque value and a response torque value corresponding to a steering wheel; obtaining a zero offset compensation value, wherein the zero offset compensation value is used for offsetting the influence of zero offset of the torque sensor on the resultant torque of the hand torque value and the response torque value; determining a target resultant moment according to the hand torque value, the response torque value and the zero offset compensation value; judging whether the target resultant moment is greater than a first threshold value or not; if not, determining that the driver slips out of the steering wheel. According to the scheme provided by the invention, the difference of vehicles with different vehicle conditions can be overcome, the accuracy of hand release detection is improved, and the false alarm rate and the missing report rate are reduced.

    本申请涉及一种脱手检测方法及装置。该方法包括:获取方向盘对应的手力扭矩值和响应扭矩值;获取零偏补偿值,所述零偏补偿值用于抵消扭矩传感器的零点偏置对所述手力扭矩值和所述响应扭矩值的合力矩的影响;根据所述手力扭矩值,所述响应扭矩值和所述零偏补偿值确定目标合力矩;判断所述目标合力矩是否大于第一阈值;若否,则确定驾驶员脱手方向盘。本申请提供的方案,能够克服了不同车况车辆的差异性,提升脱手检测的准确度,降低其误报率、漏报率。
