The invention relates to the technical field of advanced driving assistance systems, in particular to a vehicle steering wheel and a hand leaving detection method thereof.The vehicle steering wheel comprises a steering wheel body, and the steering wheel body is divided into a plurality of areas; the plurality of heating wires are arranged on the heating layer, the plurality of heating wires and the plurality of areas are arranged in a one-to-one correspondence manner, and each heating wire is uniformly distributed in the corresponding area and is used for heating the steering wheel body; the plurality of detection lines are arranged on the heating layer, the plurality of detection lines and the plurality of areas are arranged in a one-to-one correspondence manner, and when each detection line is subjected to grip strength of a driver, the detection line and the heating wire in the corresponding area form a hand detection electrode to generate a hand holding signal of the driver, and when the driver leaves the hand, a hand leaving signal of the driver is generated. Therefore, the problems that the vehicle cost is increased, the manufacturing process is complex and the vehicle using experience of a user is reduced when a shielding layer is additionally arranged on the heating pad and the thickness of the steering wheel is increased in the related technology are solved.

    本申请涉及高级驾驶辅助系统技术领域,特别涉及一种车辆方向盘及其离手检测方法,其中,车辆方向盘包括:方向盘本体,方向盘本体上划分为多个区域;布置于加热层的多根加热丝,多根加热丝与多个区域一一对应设置,每根加热丝均匀分布在对应的区域内,用于对方向盘本体加热;布置于加热层的多根检测线,多根检测线与多个区域一一对应设置,每根检测线在受到驾驶员握力时,与对应区域内的加热丝形成人手检测电极,产生驾驶员的手握信号,并在驾驶员离手时,产生驾驶员的离手信号。由此,解决了相关技术中在加热垫上增加屏蔽层,增加方向盘厚度的同时,增加车辆的成本,制作工艺较复杂,降低用户的用车体验的问题。
