In order to achieve the purpose, the invention is realized by the following technical scheme:
an active safe driving early warning method based on 5G low delay and Beidou navigation comprises the following steps:
s1, installing a locator on the vehicle, connecting the locator with the vehicle ECU, and wirelessly connecting the vehicle ECU with the Beidou navigation system through a 5G network for transmitting the position of the vehicle to the Beidou navigation system in real time;
s2, a driver plans a driving route on vehicle-mounted navigation of the vehicle, the driving route is sent to a Beidou navigation system, and the Beidou navigation system collects the driving route of the vehicle in a certain area;
s3, the Beidou navigation system sends the real-time road conditions of the road section where the vehicle is located to the corresponding vehicle ECU according to the position of the locator;
s4, detecting the distance between objects around the vehicle and the vehicle by using a vehicle body sensor of the vehicle, and comprehensively judging the road condition of the vehicle in the driving process by combining with real-time road condition information transmitted by a Beidou navigation system;
s5, the vehicle ECU calculates the traveling path of the vehicle and the time of arrival at a certain point based on the planned traveling route of the vehicle-mounted navigation of the vehicle, and determines whether or not the other vehicle or the object appears at the same point at the same time when the vehicle arrives at the certain point by comparing the traveling path of the other vehicle with the traveling path of the vehicle, thereby determining whether or not the condition for continuing the traveling is satisfied.
S6, when the vehicle ECU judges that the driving conditions are not met, reminding a driver of decelerating or changing a driving route through voice broadcast; if the vehicle continues to run and reaches the minimum safe distance judged by the vehicle ECU, the vehicle ECU controls a braking system of the vehicle to force the vehicle to decelerate until the vehicle stops; after the driving condition is ensured to be met, the driver is informed of danger relief through voice broadcasting, and the driver can drive the automobile to continue driving.
Compared with the prior art, the invention has the beneficial effects that:
the active safety system based on the 5G network and the Beidou navigation system can collect data according to road condition information provided by the Beidou navigation system and vehicle information provided by the vehicle sensors, comprehensively judges the motion tracks of the vehicle and nearby objects through an algorithm built in the vehicle ECU, and comprehensively judges whether the vehicle accords with the driving conditions or not by combining with information transmitted by the vehicle body sensors, so that accurate prejudgment is made to control the driving state of the vehicle, the condition that the judgment of the vehicle sensors is inaccurate due to the blockage of a preceding vehicle or other obstacles is effectively avoided, the vehicle can prejudge whether danger occurs or not if the vehicle continues to drive, corresponding measures are actively made, the risk of collision of the vehicle is reduced, and personal property and safety are protected.
