Embodiment Construction

[0035] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 It shows a structural schematic diagram of the automatic speed limit system of the present invention.

[0037] Depend on figure 1 It can be seen that the automatic vehicle speed limit system includes: a speed sensor 101 for sensing the vehicle speed; a controller 102 for issuing a speed limit command when the vehicle speed value is greater than a preset speed limit value; a speed limit execution device 103, Based on the speed limit instruction, the vehicle speed is limited; the preset speed limit value adjusting device 104 is used for manually adjusting the preset speed limit value.

[0038] This design makes the preset speed limit value no longer a single fixed value, and the driver can flexibly adjust the preset speed limit value according to road conditions and personal habits.

[0039] According to the pre...

Abstract

The invention discloses a system and a method for automatically limiting vehicle speed, and relates to the field of vehicle speed control. The system for automatically limiting vehicle speed comprises a speed sensor, a controller, a speed limiting executive device and a preset speed limiting value adjusting device. The speed sensor is used for sensing a vehicle speed value. The controller is used for sending a speed limiting order when the vehicle speed value is larger than a preset speed limiting value. The speed limiting executive device is used for limiting vehicle speed based on the speed limiting order. The preset speed limiting value adjusting device is used for adjusting the preset speed limiting value in a manual mode. According to the system for automatically limiting vehicle speed, a driver can flexibly adjust the preset speed limiting value so that a vehicle can be suitable for different road conditions, and speed limiting requirements of different drivers are met.

Description

technical field [0001] The invention relates to the field of vehicle speed control, in particular to a vehicle speed automatic limiting system and method. Background technique [0002] According to statistics, at present, more than 60% of the accidents on the highway are caused by speeding; in our daily life, there is also a saying of "nine disasters out of ten". Therefore, it is very positive to install a device that can automatically limit the speed of the vehicle on the vehicle so that the maximum speed of the vehicle is always lower than the preset speed limit value. [0003] In a Chinese utility model authorization public document (authorization announcement number is CN2161886Y, titled automobile speed limiting device), it discloses a technical solution for automatically limiting the speed of the automobile when the speed of the automobile exceeds the preset speed limit value. However, its preset speed limit value is a fixed value that has been adjusted by the manufac...
