The invention provides a vehicle and a steering angle detection device thereof.The steering angle detection device comprises a driving gear, a driven gear, a first angle detection module and a processing module, the driving gear is connected to a steering shaft in a sleeving mode, and the driven gear is meshed with the driving gear; the transmission ratio of the driving gear to the driven gear is configured to enable the rotation angle of the driven gear to be smaller than or equal to half cycle when the steering shaft rotates to the limiting position in any direction from the return position, the first angle detection module is configured to detect the rotation angle of the driven gear to obtain a first detection angle, and the processing module obtains the first detection angle; and the rotation angle of the driving gear is determined according to the first detection angle and the transmission relation between the driving gear and the driven gear, so that the rotation angle of the steering shaft is obtained. According to the steering angle detection device, the number of parts is reduced, the system structure is simplified, practicability is high, and popularization is easy.
本发明提供了一种车辆及其转向角度检测装置,该转向角度检测装置包括主动齿轮、从动齿轮、第一角度检测模块以及处理模块,主动齿轮套接于转向轴,从动齿轮与主动齿轮相啮合,且主动齿轮与从动齿轮的传动比配置成当转向轴从回正位置转至任一方向极限位置,从动齿轮的转动角度小于等于半周,第一角度检测模块配置成检测从动齿轮的转动角度,以得到第一检测角度,处理模块获取第一检测角度,并根据第一检测角度、以及主动齿轮与从动齿轮之间的传动关系,确定出主动齿轮的转动角度,从而得到转向轴的转动角度。本发明的转向角度检测装置降低了零件数量,简化了系统结构,实用性强,易于推广。
