Display device for acceleration/deceleration state of automobile

Abstract

The invention relates to a display device for an acceleration / deceleration state of an automobile. The display device is characterized by consisting of an automobile odometer sensor, a signal processor and a display array light emitter. The display array light emitter of the display device is mounted at the rear part of the automobile to provide indication information on the actual change of a moving speed of the automobile for a rear automobile, so that the display device has the characteristics of instant display, practical information and clear display mode. The rear automobile can instantly accelerate an accelerator so as to correspondingly advance in an accelerating manner and keep an original distance between the two automobiles when the front automobile is accelerated through observing the acceleration / deceleration state displayed by the display array light emitter of the front automobile, and thus the running efficiency is increased; and the accelerator of the rear automobile is instantly decelerated to correspondingly advance in a decelerating manner when the front automobile is decelerated, so that the occurrence of rear-end collision accidents is prevented.

Description

Technical field [0001] The invention relates to a display device for the acceleration and deceleration state of an automobile. It is an indicator light installed on the rear of the automobile to display information about changes in the running speed of the vehicle, that is, the vehicle is in an acceleration and deceleration state during operation. Background technique [0002] At present, there is no device on the car to indicate the speed change to the rear. The driver of the rear car can only judge the state of the speed change of the front car based on experience. Even if the change in the speed of the car in front can be judged based on experience, it often takes a long time. , It is difficult to find out instantly. Automobile brake lights can display the brake operation actions of the car driver, but cannot reflect the specific information of the change in the running speed of the car itself, let alone the change in the running speed of the car caused by the change in fuel s...

[0002] At present, there is no device on the car to indicate the change of running speed to the rear. The driver of the rear car can only judge the state of the running speed change of the front car based on experience. Even if the change of the speed of the front car can be judged based on experience, it often takes a long time. , it is difficult to achieve instant detection

What the car brake light can display is the brake operation action of the car driver, but it cannot reflect the specific information of the change in the running speed of the car itself, let alone the change in the running speed of the car caused by the change of fuel supply.

At present, the various rear display lights of the car cannot provide the actual change information of its moving speed to the rear, which is very unfavorable for the rear car to grasp the speed change of the front car in time and take corresponding operations to avoid misjudgment and accidents
