Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a vehicle-road coordinated vehicle automatic start-stop control system is composed of a roadside unit 2 and a vehicle-mounted unit 6; The traffic control signal reading module 8 of signal lamp 1 phase status and cycle time information (see figure 2 ) and the roadside communication module 9 (see figure 2 ) form, used to configure the on-board unit 6 (see image 3 ) of the vehicle 7 to send the geographical location information of the road intersection, the phase state of the traffic signal light 1 and the cycle time information; 7 and the distance information between the road intersection and the phase status and cycle time information of the traffic signal light 1; according to the vehicle start-stop control logic (see Figure 4 ), main control module 10 (see image 3 ) is judged through calculation...

Abstract

The invention discloses an automatic automobile start and stop control system based on automobile and road coordination. The system consists of a road side unit and a vehicle-mounted unit, wherein the road side unit is used for transmitting geographical position information of a road intersection, a phase state of a traffic signal light and period time information to a vehicle with the vehicle-mounted unit; the vehicle-mounted unit is used for acquiring the current speed of the vehicle, distance information between one vehicle and another vehicle, distance information between the vehicle and the road intersection and the phase state of the traffic signal light as well as the period time information; a main control module carries out calculation processing and judgment according to a vehicle start and stop control logic; and an instruction of decelerating, stopping or starting the vehicle can be sent according to facts whether the distance between one vehicle and another vehicle is greater than a safe vehicle distance and whether the vehicle can directly pass through the road intersection without stopping, so that automatic start and stop control over the vehicle can be realized. The automatic automobile start and stop control system has the advantages that the stay time of the vehicle at the road intersection can be shortened; and if the automatic automobile start and stop control system is used in a large scale, the emission and energy consumption of a traffic system are obviously reduced.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and relates to a vehicle-road coordinated vehicle automatic start-stop control system when the vehicle passes through a signal-controlled road intersection. Background technique [0002] With the rapid growth of car ownership, traffic congestion at urban road intersections occurs frequently, which not only reduces road traffic capacity, but also increases the idling time of cars, which not only leads to increased fuel consumption, but also aggravates the environment. degree of pollution. Therefore, the technological method that makes automobile efficiently and safely pass through road intersections has always been an issue that people pay close attention to. At present, the existing automatic start-stop control technology of automobile is to control the automatic start-stop of automobile with computer. The start-stop control unit is based on the acquisition of vehicle-related status informati...
