Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0040] figure 1 It is a flow chart of the steps of the method embodiment of the present invention, such as figure 1 Shown, the embodiment of the present invention provides a kind of speed limit method of automobile, it is characterized in that, comprises:

[0041] Step 101, turning on the speed limit mode of the car to obtain the set first speed limit;

[0042] Step 102, the camera acquires video data around the road, and the camera control unit recognizes the speed limit sign on the speed limit sign from the video data, thereby obtaining a second speed limit;

[0043] Step 103, judging whether the second speed limit is lower than the first speed limit, if yes, use the second speed limit as the current speed limit, otherwise use the first speed limi...

Abstract

The invention discloses a speed limiting method for an automobile. The speed limiting method includes: step one, a speed limiting mode of the automobile is started, and a first set limiting speed is obtained; step two, a camera obtains video data on the periphery of a road, a camera control unit distinguishes a speed limiting logo on a speed limiting board from the video data, and a second limiting speed is obtained; step three, whether the second limiting speed is less than the first limiting speed is judged, if on yes judgment, the second limiting speed is used as the current limiting speed, and if on no judgment, the first limiting speed is used as the current limiting speed; and step four, vehicle speed is controlled according to the current limiting speed. Through a mode that a vehicle is adapted to the limiting speed on the speed limiting board automatically, the speed limiting method enables the vehicle to be kept in a relatively safe vehicle speed range, prevents the vehicle from speeding, and reduces possibility of vehicle traffic accidents.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile speed limiting method and a speed limiting device. Background technique [0002] In our daily life, we often hear the phrase "nine out of ten accidents are fast", which shows that fast speed is considered to be one of the most important factors causing traffic accidents. In order to reduce the speed of vehicles on dangerous road sections, road The traffic department, according to the road alignment characteristics and traffic accident statistics, limits different vehicle speeds for different road sections, and prompts them in the form of speed limit signs. But for some drivers, often due to speculation or carelessness, they exceed the speed limit sign, causing unnecessary tickets or even a traffic accident. [0003] For the limit of the speed of the car, there is already a speed limiter technology, which is generally: EMS (Engine Management System, engine manag...
