A steering wheel out-of-hand detection system is applied to the technical field of automatic driving. The method comprises a first conductive layer, a second conductive layer, an insulating layer and a processing module. The insulating layer is arranged between the first conductive layer and the second conductive layer, and the distance between the first conductive layer and the surface of the steering wheel is different from the distance between the second conductive layer and the surface of the steering wheel. The processing module is used for identifying the holding state of the steering wheel based on the ratio of the first capacitance value to the second capacitance value, and further determining whether the steering wheel is in a hand-off state based on the holding state of the steering wheel. In the scheme, based on the capacitance value ratio of the two conductive layers, two states of holding the steering wheel without wearing the gloves and holding the steering wheel with the gloves can be effectively identified, and further whether the steering wheel leaves the hand or not is judged based on the identified holding state of the steering wheel. The hand-leaving detection of the steering wheel can be realized under the conditions that gloves are not worn and the steering wheel is held by wearing the gloves.
一种方向盘离手检测系统,应用于自动驾驶技术领域。本申请方法包括:第一导电层、第二导电层、绝缘层和处理模块。绝缘层设置于第一导电层和第二导电层之间,且第一导电层与方向盘表面之间的距离和第二导电层与方向盘表面之间的距离不同。处理模块用于基于第一电容值和第二电容值之间的比值来识别方向盘的握持状态,进而基于方向盘的握持状态进一步确定方向盘是否处于离手状态。本方案中,基于两层导电层的电容值比值,能够有效地识别不戴手套握方向盘以及戴手套握方向盘的两种状态,进而基于所识别到的方向盘握持状态进一步判定方向盘是否离手,保证在不戴手套以及戴手套握持方向盘等情况下均能够实现方向盘离手检测。
