The invention relates to a hand release detection method and device. The method comprises the following steps: acquiring a torque signal generated by a steering wheel within a first preset time length; filtering the torque signal to obtain a target torque signal; determining change rate information of the target torque signal; and if the change rate information meets a preset condition, determining that the driver slips out of the steering wheel within the first preset time duration. According to the scheme provided by the invention, interference of zero drift and a road environment can be avoided, and the detection accuracy is improved.
本申请涉及一种脱手检测方法及装置。该方法包括:获取第一预设时间长度内方向盘产生的扭矩信号;对所述扭矩信号进行滤波处理得到目标扭矩信号;确定所述目标扭矩信号的变化率信息;若所述变化率信息满足预设条件,则确定驾驶员在所述第一预设时间长度内脱手方向盘。本申请提供的方案,能够避免零点漂移和路面环境的干扰,提升检测的准确率。
