Problems solved by technology

my country is the country with the most serious automobile traffic accidents in the world. Most of the accidents are caused by rear-end collisions. The rear-end collisions are generally caused by the driver of the rear vehicle erroneously judging the safe driving distance from the vehicle in front, or Did not have a good understanding of the driving intention of the vehicle in front, and the brakes were not timely, resulting in a rear-end collision

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 , Figure 1A , Figure 1B As shown, a vehicle speed sensor 3 is installed on the wheel drive shaft of any wheel of an existing automobile. Rangefinder 5 and the controller 2 (fixed with a box) designed by the present invention are placed in the trunk of the existing car, but the rangefinder 5

[0019] In the present invention, the vehicle speed sensor 3 is a linear speed sensor, and the displacement increment per unit time is the speed.

[0020] In the present invention, the range finder 5 is a laser range finder, and the laser emitted by the range finder 5 is received by the range finder 5 after being reflected by the rear vehicle body, and the range finder 5 simultaneously records the time of the laser back and forth. Half of the product of the speed of light and the round-trip time is the relative distance L between the vehicle and ...

Abstract

The invention discloses an automobile safety tail lamp control device with lamplight language. The automobile safety tail lamp control device consists of an automobile speed sensor, a range finder and a controller. The controller comprises a singlechip, a lamplight drive circuit and an interface circuit, wherein a safety distance prompt module is stored inside the singlechip. After the singlechip processes a received front automobile speed Vm and a relative distance Ln in the safety distance prompt module, an enabled instruction f of the lamplight language of a high-position brake tail lamp is obtained and outputted to the lamplight drive circuit which controls the different statuses of the high-position brake lamp through turning on / off a relay. The control device can intelligently calculate and forecast the optimum safety distance on different driving conditions according to the real speeds of front and back automobiles and the distance change.

Description

technical field [0001] The invention relates to a control device suitable for the display of automobile tail lights, more particularly, a control device for changing the light language of the vehicle's high-mount brake light for braking. Background technique [0002] In the field of automobile technology, safety, environmental protection and energy-saving technology are the three major themes of the current development of automobile technology. Among them, safety technology has become a top priority in the future development of automobile technology because it is directly related to personal life and property loss. Work. [0003] In the car safety warning function, the light and sound alarm are the main contributors to the prevention of traffic accidents, because the driver's capture and intake of road condition information mainly comes from the eyes, especially to maintain a safe distance from the vehicle in front. Therefore, the car The role of light signals, especially t...
