Embodiment Construction

[0037] In order to make the purpose of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] Such as figure 1As shown, the vehicle speed control system 1 of the present invention includes a vehicle condition detection module 2, a decoding module 3 connected to the vehicle condition detection module 2 by a vehicle bus, a vehicle navigation terminal 4 connected to the decoding module 3 through a serial port, and a vehicle navigation terminal connected to the vehicle condition detection module 2. 4. The vehicle speed limit controller 5 connected through the I / 0 port. The vehicle condition detection module 2 is used to collect and save vehicle driving data including the position information of the vehicle shift lever, ...

Abstract

The invention discloses a vehicle speed control method and system. The vehicle speed control system (1) comprises a vehicle condition detection module (2), a decoding module (3), a vehicle-mounted navigation terminal (4) and a vehicle speed limit controller (5). The decoding module (3) obtains vehicle driving data detected by the vehicle condition detection module (2); the vehicle-mounted navigation terminal (4) determines an allowable safety vehicle speed threshold value in the current vehicle driving process through the vehicle driving data and stored reference data, enables the safety vehicle speed threshold value to the compared with a vehicle speed value in the vehicle driving data, and controls a loudspeaker module (15) to play vehicle speed warning voice through a comparison result or slows down a vehicle through the vehicle speed limit controller (5), and therefore the speed of the vehicle is reduced to below the safety vehicle speed threshold value. According to the vehicle speed control system, deceleration treatment can be automatically carried out on the vehicle under the overspeed condition; and the incidence rate of collision accidents in the vehicle driving process is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle safety driving, and more specifically, relates to a vehicle speed control method and system. Background technique [0002] During the reversing process, the user usually needs to use the voice reminder function of the reversing radar and the image information captured by the reversing camera to adjust the speed of the vehicle. However, in the prior art, the reversing radar can only start working when the distance between the vehicle and the obstacle reaches its detection range, displaying the distance between the vehicle and the obstacle. Therefore, the reversing radar can only passively remind the user during the reversing process. The details of the reversing image captured by the reversing camera are not fine enough. [0003] When the user performs a reversing operation in a dim environment, since the reversing camera cannot obtain a clear image in a low-light environment, it is diffi...
