Problems solved by technology

[0004] The purpose of the present invention is to solve where pedestrians are when crossing the road, which route to choose, and other pedestrians crossing the intersection in a dangerous way, as well as overcrowded intersections, which make the road more dangerous. If there is a problem The environment does not change, the behavior of other traffic participants corresponding to pedestrians is not standardized, and the bad habit of pedestrians running red lights may be difficult to uproot. A control system and method for safe and intelligent driving of automobile traffic lights and zebra crossings is proposed

Embodiment 1

[0060] see Figure 5-6 As shown, each route is positioned and navigated by the GPS satellite transmitter 3, and the demarcated route is driven, and the vehicle controller 4 receives the route direction transmitted by the in-vehicle radar 2 to drive. The intersection radar 1 and the in-vehicle radar 2 During the network conversion signal sent by GPS satellite transmitter 3, when the green light signal of the straight road is sent, the distance L1 and speed V1 signal between the intersection radar 1 and the car radar 2 are collected, and the safe distance L and the safe speed of the vehicle to the zebra crossing are set. V; when the turning green light signal is sent, the radar 2 in the car receives the signal, and sends it to the vehicle controller 4 to turn on the direction light; the two driving modes pass the vehicle intersection radar 1 and the radar 2 in the car. The distance L1 is greater than or equal to the arrival of the vehicle When the safety distance L of the zebra ...

Embodiment 2

[0062] See 5 and Figure 7As shown, each route is positioned and navigated by the GPS satellite transmitter 3, driving on the marked route, the vehicle controller 4 receives the route direction transmitted by the in-vehicle radar 2 to drive, when the driving vehicle enters the set zebra crossing safety distance , the distance sensor 9 detects the distance between the vehicle 11 and the pedestrian through body position mutual induction, and sends out a distance signal, collects the signal of the distance L2 and the speed V2 between the radar and the pedestrian in the intersection, and sets the safe distance L3 and the safe speed from the vehicle to the pedestrian V3, when the distance L1 between the vehicle intersection radar 1 and the vehicle radar 2 is less than or equal to the safe distance L between the vehicle and the zebra crossing, and the speed V1 is less than the safe speed V, the vehicle enters the intelligent driving state and displays the distance and speed to the ze...

Embodiment 3

[0064] see Figure 5 and Figure 8 As shown, each route is positioned and navigated by the GPS satellite transmitter 3, and the demarcated route is driven, and the vehicle controller 4 receives the route direction transmitted by the in-vehicle radar 2 to drive. The intersection radar 1 and the in-vehicle radar 2 Through the network conversion signal sent by the GPS satellite transmitter 3, the distance L4 between the intersection radar 1 and the vehicle radar 2, the speed V4 signal, and the remaining time T1 signal from the green light to red light are collected, and the safe parking distance before the zebra crossing or the vehicle-to-vehicle distance is set. The safe distance L5 between, the safe speed V5, and the safe time T, through the collected signal between the crossroad radar 1 and the vehicle radar 2 through the GPS satellite transmitter 3, the remaining time T1 signal for green light to red light change, when The remaining time T1 from green to red is greater than ...

Abstract

The invention discloses a control system for safe and intelligent driving of automobile traffic lights and zebra crossings. Sensors and traffic light intelligent platform, the GPS satellite transmitter is used to convert the traffic light intelligent platform to send out traffic light signals. Beneficial effects of the present invention: the present invention can replace people in the "manually driven" motor vehicle to predict deceleration, give way to pedestrians or stop in advance at zebra crossing traffic light intersections, and create more safety conditions for pedestrians crossing the road; the present invention effectively reduces Or put an end to traffic accidents at zebra crossing traffic light intersections, reduce the number of deaths, and save more people's lives; the structure principle of the invention is clear and simple, easy to assemble, can be used in the new energy development industry, can be industrialized and applied in batches, and is easy to promote .

Description

technical field [0001] The invention relates to a control system, in particular to a control system and method for safe and intelligent driving of automobile traffic lights and zebra crossings, and belongs to the technical field of control system applications. Background technique [0002] According to the data released by the Traffic Management Bureau of the Ministry of Public Security, in the past three years, there have been 14,000 motor vehicle and pedestrian traffic accidents on zebra crossings across the country, resulting in 3,898 deaths, of which accidents caused by motor vehicles not giving way according to regulations accounted for the total. 90%. From the analysis of the causes of the accident, one is that the motor vehicle did not give way as required when passing the crosswalk, and the other is that the pedestrian ran the red light and had an accident with the motor vehicle that was passing the green light. According to statistics, the accidents caused by motor...
