Embodiment Construction

[0021] In order to make the present invention more comprehensible, preferred embodiments are described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the present invention provides a vehicle intelligent speed limiting system, comprising: an engine electronic control unit, a vehicle speed sensor connected to the input end of the engine electronic control unit, an engine speed sensor and a GPS navigation module, connected to the engine electronic control unit The speed limit actuator at the output end; the GPS navigation module is used to detect the speed limit value of the road where the vehicle is located, and transmits the speed limit value to the engine electronic control unit; the vehicle speed sensor is used to detect the current driving speed of the vehicle, and transmit the driving speed to the engine electronic control unit;

[0023] The engine electronic control unit receives and calculates the speed limit value and ...

Abstract

The invention discloses a vehicle intelligent speed limit system and method. A GPS (Global Positioning System) navigation module detects a highest speed limit value of a road in which a vehicle is located currently; a vehicle speed sensor detects the vehicle driving speed; an engine electronic control unit limits the vehicle speed within a regulated speed range through a closed loop speed limit control and regulate throttle valve and an oil atomizer according to the differences between the current vehicle speed and the highest speed limit value; meanwhile the engine electronic control unit lights a brake lamp when performs speed limit motions to warn other vehicles and guarantee safety; a warning is sent to a driver of the vehicle through a voice prompt system to enable the driver to know speed limit conditions. The vehicle intelligent speed limit system and method has the advantages of monitoring the road section in which the vehicle is arranged and the current vehicle speed in real time, improving the vehicle driving safety due to the fact that the electronic control unit initiatively limit the vehicle speed intelligently according to the requirements and meanwhile reducing the working pressure of traffic management departments to some extent.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle intelligent speed limiting system and method. Background technique [0002] Due to the large differences in the maximum speed limit values ​​of various roads in China, the road speed limit signs are not clear enough. It is very easy to cause vehicles to overspeed, which brings greater management pressure to the traffic department and also brings greater safety hazards to users. [0003] At present, the methods to solve the above-mentioned problems mainly include: developing the speed limit function of the vehicle, setting the maximum speed limit artificially; installing a control device on the brake pedal, etc., and actively intervening to limit the speed of the vehicle when the vehicle speed reaches the maximum limit. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a simple and low-cost improvement pl...
