The invention discloses a vehicle safety warning system, a warning information sending method and a warning information receiving method. The system comprises: a processing module which is used for generating danger warning information according to vehicle state information and position information; an HMI module used for generating a transmission confirmation instruction in a preset sending mode according to the danger warning information transmission request; a processing module used for sending the danger warning information to the security module according to the transmission confirmation instruction, and transmitting the signature encrypted danger warning information returned by the security module to the V2X communication module; and a V2X communication module is used for broadcasting the danger warning information subjected to signature encryption to vehicles in a specified range in a V2X message form. Under the condition that the current vehicle breaks down, the legality danger warning information can be generated, and the danger warning information is sent to the vehicles in the specified range through the V2X communication module, so that the vehicles in the specified range know the danger condition of the vehicles on the road ahead in advance to avoid, and the driving safety of the vehicles on the road is improved.

    本发明公开了一种车辆安全警示系统、警示信息发送、接收方法,包括:处理模块,用于根据车辆状态信息和位置信息生成危险警示信息;HMI模块,用于根据危险警示信息传输请求按照预设发送方式生成确认传输指令;处理模块,用于根据确认传输指令将危险警示信息发送给安全模块,并将安全模块所返回的签名加密后的危险警示信息传输给V2X通信模块;V2X通信模块,用于将签名加密后的危险警示信息以V2X消息的形式向指定范围内的车辆进行广播。在当前车辆发生故障的情况下可以生成合法性的危险警示信息,并将危险警示信息通过V2X通信模块发送给指定范围内的车辆,使指定范围内的车辆提前获知前方道路车辆危险情况以进行避让,从而提高了道路车辆驾驶的安全性。
