The invention relates to a signal lamp state speculation method, which comprises the following steps of: when detecting that a current vehicle enters an intersection and loses a signal lamp identification signal, sending a communication request to roadside equipment, and if the current vehicle is successfully connected with the roadside equipment, receiving historical cache data pre-packaged by the roadside equipment to speculate the current signal lamp state, executing a driving strategy corresponding to the speculation result; if the current vehicle fails to be connected with the roadside equipment and is successfully connected with the surrounding vehicles, signal lamp state information sent by the surrounding vehicles is received, the current signal lamp state is speculated, and a corresponding driving strategy is executed, otherwise, the current signal lamp state is speculated based on the two signal speculation methods, and the corresponding driving strategy is executed. And determining and executing a corresponding driving strategy according to the two speculation results. Compared with the prior art, the road signal lamp can be accurately speculated under the situation that signal lamp perception and recognition cannot be performed through the vehicle sensor.
本发明涉及一种信号灯状态推测方法,包括如下步骤:检测当前车辆进入路口,且丢失信号灯识别信号时,向路侧设备发送通信请求,若当前车辆与路侧设备连接成功,接收由路侧设备预先打包的历史缓存数据对当前信号灯状态进行推测,执行与推测结果相应的行驶策略;若当前车辆与路侧设备连接失败,且与周围车辆连接成功,接收由周围车辆发送的信号灯状态信息,并对当前信号灯状态进行推测,执行相应的行驶策略,否则基于两种信号推测方法对当前信号灯状态进行推测,根据两个推测结果确定并执行相应驾驶策略。与现有技术相比,本发明能够在无法通过本车传感器进行信号灯感知识别的情景下,对道路信号灯进行准确的推测。
