Problems solved by technology
[0003] The purpose of the present invention is to overcome the disadvantages that the existing radar speed measuring device can only measure and record illegal speeding and cannot effectively control the vehicle speed, and provide a method and system for vehicle speed limit and safety distance control. The system can not only measure in real time The driving speed of the vehicle can also measure the distance between the front and rear vehicles in the same lane in real time, and when the vehicle speed exceeds the speed limit or the distance between the two vehicles is shorter than the safe distance, it will send out an audible and visual alarm signal to remind the driver to reduce the speed of the vehicle. Speed, if the driver does not take measures to reduce the speed within the set time after the warning signal is issued, the system will automatically activate the speed limit control actuator to reduce the driving speed

Embodiment Construction
[0066] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing:
[0067] A method for vehicle speed limit and safety distance control provided by the present invention includes a vehicle speed detection and control method and a vehicle distance detection and control method. The computer program in the speed limit and vehicle distance control single-chip microcomputer is realized, figure 1 is a flow chart of the vehicle speed detection and control method, figure 2 It is a flow chart of the vehicle distance detection and control method.
[0068] figure 1 Among them, in order to detect and control the speed of the vehicle, a wireless speed limit data signal transmitter should be installed beside the road to send the speed limit data of the road section to the passing vehicles. A plurality of devices are arranged in different road sections on the whole highway, especially on the expressway. The vehicle is equipped with a w...

Present invention discloses a car speed limiting and safety spacing controlling method and system. It contains one or more of wireless speed limiting data signal transmitter, a wireless lane signal transmitter, a speed of a vehicle and spacing detect and controller, speed limiting controlling actuator. Speed and spacing detect and controller receives speed limiting data from wireless speed limiting data signal transmitter and receiving lane information from wireless lane signal emission device in front and same lane, judging whether overspeed or two vehicle spacing safety according to received speed limiting data, lane information detective running speed, if overspeed or following distance following distance not safety then acousto-optic alarm prompting driver reducing running speed, if driver can not taking action for reducing speed within preset time then said system starting up speed limiting controlling actuator to reduce speed. Said invention can effectively control vehicle running speed, endure drive and passenger safety and keep road unblocking.
Description
technical field [0001] The invention relates to an automatic control method and system, in particular to a method and system for speed limit and safety distance control of automobiles. technical background [0002] According to domestic and foreign traffic rules, there are speed limits for cars traveling in various areas to control the speed of cars and prevent and reduce the occurrence of traffic accidents. At present, radar speed measuring devices are widely used at home and abroad to measure the speed of illegal speeding vehicles, combined with measures such as on-site speed measurement, interception and punishment, to control and punish violating drivers, and to maintain smooth roads and traffic safety. The post-event punishment for speeding cars and the education of drivers and passengers cannot fundamentally solve the real-time detection and effective control of the speed of cars. Contents of the invention [0003] The purpose of the present invention is to overcome...
