The invention discloses a steering wheel holding state detection method which comprises the following steps: after an ADAS system is started, acquiring vehicle state data and road data in real time; the vehicle state data and the road data are compared with pre-calibrated threshold values, detection standards of current corresponding handheld state detection are determined, and the detection standards comprise a high-sensitivity detection standard and a low-sensitivity bottom detection standard; and according to the detection standard of the current hand-held state detection, the hand-held state of the steering wheel is detected in combination with the null drift value of the torque sensor in the EPS system. The invention further discloses a corresponding system. By implementing the embodiment of the invention, additional hardware cost does not need to be increased, the sensitivity and accuracy of the hand-held state detection of the steering wheel can be enhanced, and the scene applicability is good.

    本发明公开了一种方向盘的手扶状态检测方法,其包括步骤:在ADAS系统开启后,实时获取车辆状态数据与道路数据;根据所述车辆状态数据、道路数据与预先标定的阈值进行比较,确定当前对应的手扶状态检测的检测标准,所述检测标准包括:高灵敏度检测标准和低灵敏底检测标准;根据当前的手扶状态检测的检测标准,结合EPS系统中扭矩传感器的零漂值,检测方向盘的手扶状态。本发明还公开了相应的系统。实施本发明实施例,无需额外增加硬件成本,能够增强方向盘的手扶状态检测的灵敏度和准确率,且场景适用性好。
