Embodiment Construction
[0024] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 Shown is the principle frame diagram of the vehicle speed limit control system of the intelligent road section of the present invention, as can be seen from the figure, the system includes a vehicle-mounted speed-limiting device and a server connected by wireless communication with it, and the vehicle-mounted speed-limiting device includes a speed-limiting controller and a control connection with it engine ECU, the system also includes a remote service terminal, which is used to transmit the speed limit information set according to the needs or actual environmental conditions to the server for storage; the server is used to store the speed limit issued by the remote service terminal Speed information and automatically analyze and send the speed limit information to the vehicle speed limit device when receiving the spe...

The invention discloses an intelligent vehicle speed-limiting control system and method according to road segments. Speed-limiting values are not pre-set in a server and vehicle-mounted speed-limiting equipment, a speed-limiting fence is established by a remote service terminal according to requirements, reasonable speed-limiting values stored in the server are updated in real time, and therefore the speed-limiting values are adjusted in real time according to actual environmental information such as a road condition. The matching of the speed-limiting fence and a gridding ID is completed automatically by the server, a speed-limiting fence request and execution of accessing a new gridding are completed automatically by the vehicle-mounted speed-limiting equipment, the speed-limiting fence is sent automatically after the server receives the request information of the vehicle-mounted speed-limiting equipment, an on-demand request and the execution of the speed-limiting fence are achieved by the vehicle-mounted speed-limiting equipment, matching work of vehicle-road segment-road path is not needed to operate frequently, and the usability of segmentation speed-limiting function is improved. Calculation of the gridding ID is distributed in the vehicle-mounted speed-limiting equipment to execute rather than concentrated in a cloud terminal, the instantaneity of the system is improved, and the performance requirement of the server is lowered.
Description
technical field [0001] The invention relates to an intelligent road section vehicle speed limit control system and method. Background technique [0002] Speeding of vehicles (especially passenger cars) is recognized as one of the main causes of traffic accidents. At present, the industry mainly monitors this violation through the voice alarm of the vehicle driving recorder, but this non-mandatory method cannot guarantee binding force. Some companies in the industry have also begun to use electronic accelerator control equipment to achieve mandatory speed limits for vehicles. However, due to the difficulty in matching equipment with the vehicle, poor real-time performance, difficulty in obtaining accurate reference speeds, and complicated control methods Disadvantages such as high failure rate are not easy and cannot be used on a large scale. [0003] With the improvement of vehicle intelligence and the application of Internet technology in the transportation industry, many ...
