Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

[0030] Please refer to figure 1 , a vehicle anti-rear-collision control method, comprising the following steps:

[0031] S1, set the number of sampling periods;

[0032] S2, collect the vehicle speed value: collect the speed value of the front and rear vehicles in each sampling period;

[0033] S3, calculate the speed difference: calculate the speed difference between the rear vehicle and the front vehicle in each sampling period;

[0034] S4, calculate the average value: calculate the average value of the speed difference within the number of sampling periods;

[0035] S5, comparing the average value with a preset value: if the average value is greater than the preset value, it is determined that there is a rear-end collision risk;

[0036] S6. Sending a prompt message: when there is a risk of ...

Abstract

The invention provides a vehicle rear-end collision prevention control method and a system thereof. The vehicle rear-end collision prevention control method comprises the steps of setting the number of sampling periods; collecting speed values of front and rear vehicles in each sampling period; calculating the speed difference between the rear and front vehicles in each sampling period; calculating the average value of the speed difference within the number of sampling periods; comparing the average value with a preset value; if the average value is greater than the preset value, determining the presence of a risk of a rear-end collision; and in the presence of the risk of a rear-end collision, sending out a prompt message. In the invention, the risk of a rear-end collision is judged by comparing the average value of the speed difference between the rear and front vehicles with the preset value, the congestion due to the introduction of a rear-end collision prevention control system isavoided, the targeted rear-end collision prompt message is sent out, and the occurrence of a rear-end collision is effectively prevented.

Description

technical field [0001] The invention relates to the field of traffic safety, in particular to a vehicle anti-rear collision control method and system thereof. Background technique [0002] Rear-end collision is the most common form of road traffic accidents. According to the statistics of China's traffic management department, rear-end collision accidents account for about 30% of the total number of road traffic accidents, and hundreds of millions of casualties and property losses are caused by rear-end collisions every year. Commonly, in order to prevent rear-end collisions, display screen reminders or sound reminders are often used on the road, and the reminder objects are for all passing vehicles, resulting in poor rear-end collision prevention effects. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a vehicle rear-end collision prevention control method and its system. Firstly, the risk of rear-e...
