Abstract

The invention relates to the technical field of automobile electronics relevant to vehicle safety driving and discloses a vehicle over-speed detection method, a vehicle over-speed detection device and a vehicle over-speed alarm system. The vehicle over-speed detection method comprises the following steps of: according to speed identification information and removal speed limit signboard information on a speed limit signboard in a shot outside image, determining a limited speed of a road section where a vehicle currently runs; according to speed indication information on a shot inside vehicle speed display instrument image, determining a current vehicle speed of the detected vehicle; and according to the current vehicle speed and the limited speed, performing over-speed detection. The vehicle over-speed alarm system comprises a vehicle over-speed detection device, a first shooting device which shoots the outside image, a second shooting device which shoots the inside vehicle speed display instrument image, and an alarm device which gives an alarm in real time during over-speed. By the invention, the over-speed of the vehicle can be automatically determined, and the alarm for over-speed can be given in real time.

Description

technical field [0001] The invention relates to the technical field of automotive electronics related to vehicle safety driving, in particular to a vehicle overspeed detection method and device and a vehicle overspeed alarm system. Background technique [0002] At present, different road sections have different speed limits. When vehicles are driving on different road sections, the speed should be limited within the speed limit corresponding to the driving section, otherwise overspeeding will occur and various dangers will occur. [0003] In order to keep the speed of the vehicle always within the speed limit corresponding to the driving section, the following methods can be used at present: [0004] 1) The driver judges by himself [0005] Set speed limit signs and corresponding release speed limit signs on different road sections. different graphs. The driver can determine the speed limit of the road section where the car is currently located through the above two signs...
