The invention discloses a vehicle safety driving warning system based on environmental perception, and relates to the technical field of vehicles. The system comprises a master control unit connected to a vehicle CAN bus, and environmental perception devices installed at the positions of wheels of a vehicle respectively. For each environmental perception device, in the vehicle driving process, an in-tire charging coil performs power supply interaction with the radio frequency charging unit, the in-tire radio frequency unit performs data interaction with the radio frequency charging unit, and driving state data collected by the wheel control unit through the sensing unit is transmitted to the radio frequency charging unit; the master control unit calculates and analyzes vehicle driving environment abnormity and whether the vehicle is abnormal or not based on the driving state data in combination with vehicle-mounted CAN data fed back by the vehicle, gives an alarm in time when the abnormity occurs, is used for providing road condition perception for a driver, and is high in timeliness, accuracy and comprehensiveness, so that the driving state can be adjusted in time. The driving safety is ensured.
本发明公开了一种基于环境感知的车辆安全行驶警示系统,涉及车辆技术领域,该系统包括接入车辆CAN总线的总控制单元,以及分别安装在车辆的各个车轮处的环境感知装置,对于每个环境感知装置,在车辆行驶过程中,胎内充电线圈与射频充电单元进行供电交互,胎内射频单元与射频充电单元进行数据交互,将车轮控制单元通过传感单元获取到的行驶状态数据传输给射频充电单元;总控制单元基于行驶状态数据结合车辆反馈的车载CAN数据,计算分析车辆行驶环境异常以及车辆自身是否存在异常,并在异常时及时警示,用于为驾车人员提供路面状况的感知,及时性、准确性和全面性都较高,以便及时调整行车状态,保证行车安全。
