A quantitative indication device and an indication method for a vehicle running state

Abstract

A quantitative indication device for a vehicle running state comprises an acceleration sensor mounted on the vehicle for obtaining an acceleration value of the vehicle; a lamp band mounted at the rearof the vehicle for quantitatively displaying acceleration of the vehicle; the control chip receives the acceleration data of the vehicle measured by the acceleration sensor and controls the lamp bandto display according to the acceleration data. The acceleration sensor is connected with the input terminal of the control chip, and the lamp band is connected with the output terminal of the controlchip. The device is reasonable in design and convenient in installation. The device is cooperated with the indication method, not only the acceleration and braking state of the vehicle can be displayed, but also the acceleration and braking degree of the vehicle can be displayed, and the following safety of the rear vehicle can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle safety, in particular to a vehicle driving state quantitative indicating device, and also relates to an indicating method of the vehicle driving state quantifying indicating device. Background technique [0002] According to statistics on the causes of traffic accidents in recent years, rear-end collisions account for about 70% of the total number of traffic accidents. Since the traditional brake light is a simple switch indicator, it can only indicate whether the driver has taken braking measures, but cannot directly reflect whether the brake light is used. After the driver of the rear car reacts to the brake lights of the front car, he still needs to judge the braking degree of the front car according to the speed at which the relative distance between the two cars decreases, which greatly lengthens the time for taking correct and appropriate braking behaviors. The response time; and whe...

[0002] According to statistics on the causes of traffic accidents in recent years, rear-end collisions account for about 70% of the total number of traffic accidents. Since the traditional brake light is a simple switch indicator, it can only indicate whether the driver has taken braking measures, but cannot directly reflect whether the brake light is used. After the driver of the rear car reacts to the brake lights of the front car, he still needs to judge the braking degree of the front car according to the speed at which the relative distance between the two cars decreases, which greatly lengthens the time for taking correct and appropriate braking behaviors. The response time; and when the vehicle in front is running in the acceleration state, there is no indicator light

[0003] However, among the models currently on the market, there is no vehicle with quantitative indication of driving status; the modified accessories only have general running water turn signals, brake flashing lights, etc., which are no different from the indicator lights of previous vehicles. More indicators to improve safe driving
