The invention relates to a vehicle course angle calculation method based on vehicle-road cloud integration, which comprises the following steps of: judging the strength of a satellite signal, directly correcting a vehicle course angle if the satellite signal is judged to be strong, otherwise, entering step (2); collecting vehicle surrounding environment information, and judging whether the vehicle is static or not; if the vehicle is judged to be static, course angle information is extracted or recognized; otherwise, correcting the course angle by using the vehicle track when the vehicle runs; when the vehicle stops running, temporarily memorizing the course angle of the current vehicle; when the vehicle is powered off, current vehicle course angle information is stored in a storage module of the cloud; and when the vehicle is electrified and started again, the course angle stored by the vehicle in the storage module of the cloud is extracted. The invention further discloses a vehicle course angle calculation system based on vehicle and road cloud integration. The problem of low course angle calculation accuracy caused by limitation of single course angle calculation is avoided, and collision in the vehicle driving process is avoided.
本发明涉及一种基于车路云一体化的车辆航向角计算方法,包括:判断卫星信号的强弱,若判断卫星信号强,直接对车辆航向角进行修正,否则,则进入步骤(2);采集车辆周围环境信息,判断车辆是否静止;若判断车辆为静止,则提取或识别航向角信息;否则,在车辆行驶时利用车辆轨迹对航向角进行修正;当车辆在行驶中停止,临时记忆当前车辆的航向角;当车辆下电时,将当前的车辆航向角信息存储到云端的存储模块中;当车辆再次上电启动时,提取云端的存储模块中该车辆存储的航向角。本发明还公开了一种基于车路云一体化的车辆航向角计算系统。本发明避免单一一种航向角计算的局限性所带来的航向角计算准确度低的问题,避免车辆行驶过程中发生碰撞。
