Problems solved by technology
In addition, because the electronic eye monitoring on the road cannot monitor every section of the road, the means of preventing speeding are not perfect, which objectively increases the probability of drivers driving illegally
There is no mature device on the market today to actively limit the speed of motor vehicles according to the requirements of the road.

The invention discloses an automobile speed-limiting driving system which comprises an image acquisition device, a vehicle speed sensor, a microprocessor and an electromagnetic valve. The image acquisition device, the vehicle speed sensor and the electromagnetic valve are all connected with the microprocessor; and both ends of the electromagnetic valve are respectively connected with a valve sensor and an engine control room of a vehicle. According to the invention, the image acquisition device is introduced to automatically search the pavement highest limited speed and obtain a vehicle speed by the vehicle speed sensor; the microprocessor is adopted to analyze data; and according to the judgment on the current vehicle speed, an engine controller is controlled to force the vehicle to run in the range of a safety speed. Namely, a method for actively forcing to prevent overspeed is adopted, so that the effect of preventing overspeed is more effective. Moreover, the automobile speed-limiting driving system is simple vehicle-mounted equipment and is low in cost, facilities such as existing traffic guide boards and the like do not need to be modified; and the automobile speed-limiting driving system has a strong operability.
Description
technical field [0001] The invention relates to the technical field of microelectronic control, in particular to an automobile speed-limiting driving system. Background technique [0002] At present, through the retrieval of literature on measures to prevent speeding, the relevant departments mainly adopt the means of combining electronic eye monitoring, street sign prompts and safe driving publicity and education to prevent motor vehicles from speeding. This means of preventing speeding is a passive means, and the driver often just knows himself speeding after the event. In addition, because the electronic eye monitoring on the road cannot monitor every section of the road, the means of preventing speeding are not perfect, which objectively increases the probability of drivers driving illegally. Also do not have a mature device in the market now, come according to the requirement of road active limit motor vehicle speed of a vehicle. [0003] Therefore, how to provide a v...
