The invention discloses a V2X device for an automatic driving system and a signal switching method, the V2X device comprises a V2X module and a main controller CPU, the V2X device provides time service and positioning signals through an external high-precision RTK device, and the V2X module is connected with the main controller CPU; the main controller CPU comprises a 1PPS signal processing unit which is used for monitoring the quality of a 1PPS second pulse signal in the external high-precision RTK equipment and generating an analog signal of the 1PPS second pulse signal under the condition that the quality of the 1PPS second pulse signal in the external high-precision RTK equipment does not meet a preset condition; the main controller CPU further comprises a first control signal interface and a second control signal interface. According to the V2X equipment provided by the invention, normal communication between the V2X equipment can still be ensured when the synchronization signal of the external high-precision RTK equipment in the V2X module is lost for a short time.

    本申请公开了一种用于自动驾驶系统的V2X设备、信号切换方法,所述V2X设备包括:V2X模组以及主控制器CPU,所述V2X设备通过外部高精RTK设备提供授时和定位信号,所述V2X模组与所述主控制器CPU连接;所述主控制器CPU包括1PPS信号处理单元,用于监控所述外部高精RTK设备中的1PPS秒脉冲信号的质量,并在所述外部高精RTK设备中的1PPS秒脉冲信号的质量不满足预设条件的情况下生成1PPS秒脉冲信号的模拟信号;所述主控制器CPU还包括第一控制信号接口和第二控制信号接口。通过本申请的V2X设备可以在V2X模组中的外部高精RTK设备的同步信号短期丢失时,依然可以保证V2X设备间的正常通信。
