The invention relates to a method and a system for detecting holding/loosening of a steering wheel by a driver's hand during driving. A driver's hand grip/release detection system that detects whether a driver's hand grips or releases a steering wheel during travel is applied to a vehicle. During driving, when the controller operates the driving assistance system, the driver's hand grip/release detection system uses the MDPS torque representative value and the vehicle measurement data representative value as the ratio of the representative values between the sensors, and divides a disturbed driving area and a normal driving area by the magnitude of the ratio of the representative values between the sensors, a sensor detection correction control for performing hand grip/release confirmation by applying an interference torque threshold value to the torque filter value, or a torque-based detection control for performing hand grip/release confirmation by applying an upper/lower torque limit value to the torque filter value, thus, a hand grip/release detection error during travel can be reduced using only the in-vehicle sensor instead of the capacitive sensor.

    本发明涉及在行驶期间检测驾驶员的手握住/松开方向盘的方法和系统。在行驶期间检测驾驶员的手是握住还是松开方向盘的驾驶员的手握住/松开检测系统应用于车辆。在行驶期间,当控制器使驾驶辅助系统运行时,驾驶员的手握住/松开检测系统将MDPS扭矩代表值和车辆测量数据代表值作为传感器之间代表值的比值,并通过传感器之间代表值的比值的大小来划分干扰行驶区域和正常行驶区域,以通过将干扰扭矩阈值应用于扭矩滤波值执行手握住/松开确认的传感器检测校正控制,或通过将上/下扭矩极限值应用于扭矩滤波值执行手握住/松开确认的基于扭矩的检测控制,从而仅利用车载传感器而不利用电容式传感器能够降低在行驶期间的手握住/松开检测误差。
