Quantitative indicator device and indicator method for vehicle driving state

Abstract

A quantitative indicator device for the driving state of a vehicle, the device includes an acceleration sensor installed on the vehicle for obtaining the acceleration value of the vehicle; a light strip installed at the rear of the vehicle for quantitatively displaying the acceleration of the vehicle; a control chip for receiving The acceleration sensor measures the acceleration data of the vehicle, and controls the light strip to display according to the acceleration data; the acceleration sensor is connected to the input terminal of the control chip, and the light strip is connected to the output terminal of the control chip. The device is reasonable in design and easy to install. With the indication method of the device, it can not only display the acceleration and braking status of the vehicle, but also the degree of acceleration and braking of the vehicle, which greatly improves the safety of following vehicles.

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 indication, 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 wh...

[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 indication, 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
