Problems solved by technology

Using the deceleration ridge to limit the speed of road vehicles, the speed limit value is fixed and cannot be adjusted, and there are potential safety problems: when the speed of passing vehicles is fast, the deceleration ridge will cause large bumps and vibrations to the vehicle, and in severe cases, it may cause serious damage to people, cars, damage to goods, etc., or may cause a traffic accident
Not suitable for wide application

Abstract

The invention discloses a road speed limiting control device, which relates to the field of traffic, machinery and electronics. The road speed limiting control device comprises a speed limiting mechanism device (1), a speed measuring device (2), a current control device (3) and an external power supply (4) which are installed on a road lane, wherein the speed measuring device (2) and the current control device (3) are respectively connected with the external power supply (4); and the speed limiting mechanism device (1) and the speed measuring device (2) are respectively connected with the current control device (3). When the running speed of a passing vehicle is lower than a limited speed of the lane, a speed limiting mechanism does not work, and the vehicle passes stably; and when the running speed of a passing vehicle is higher than the limited speed of the lane, the speed limiting mechanism works, and the overspeed vehicle is subjected to obvious bump and vibration. According to the invention, a vehicle driver is required to drive according to the limited speed through visual warning and the bump and vibration, and the safety and the humanized design of vehicle speed limiting passing control appliances are shown simultaneously.

Description

Technical field: [0001] The invention relates to the fields of traffic, machinery and electronics, and is a mechatronic control device applied in road traffic management and control, which requires drivers to drive according to speed limit control requirements through visual warnings and bumps and vibrations. Background technique: [0002] Limiting the speed of motor vehicles on the road is a common traffic management method for safe driving, reducing traffic accidents, and ensuring traffic safety. At the same time, with the rapid development of transportation and the wide application of intelligent transportation technology, limiting the speed of motor vehicles on certain roads has gradually become an important control means to regulate traffic flow on road sections and balance road network flow. [0003] In the current technology, common methods for limiting vehicle speed are setting dynamic and static speed limit traffic signs, painting road deceleration prompt markings, ...
