Active vehicle safety pre-warning method and safety pre-warning system with same applied

Abstract

The invention relates to the technical field of active vehicle safety control and the mobile internet, in particular to an active vehicle safety pre-warning method and a safety pre-warning system with the active vehicle safety pre-warning method applied. The safety pre-warning system comprises a mobile intelligent terminal, a wireless communication network and a satellite positioning system. The active vehicle safety pre-warning method includes the steps that a data preprocessing module, a line tracing and estimating module and a danger pre-warning module are installed on the mobile intelligent terminal, an own vehicle can judge whether a collision risk exists or not according to information of pedestrians and other vehicles within a target range, and a safety alarm is given if necessary. By ingenious utilization of popular smart phones, low-cost vehicles and pedestrians can enjoy protection of the active safety technology, individual privacy will not be leaked, and the active vehicle safety pre-warning method and the safety pre-warning system with the active vehicle safety pre-warning method applied are highly popular, low in cost and likely to be accepted by public.

Description

technical field [0001] The invention relates to the technical field of vehicle active safety control and mobile interconnection, in particular to a vehicle active safety early warning method and a safety early warning system using the method. Background technique [0002] The vehicle active safety control system can realize vehicle collision warning and intervention in driving operation, making driving safer and easier. In recent years, the research enthusiasm in this technical field has continued to heat up. Active safety control systems such as ACC (Adaptive Cruise Control), EBA (Emergency Brake Assist), and LKA (Lane Keeping Assist) based on radar, camera and other environmental detection sensors have matured. , and is still being optimized. For example, Korean patent KR2007023392A (ADAPTIVE CRUISE CONTROL SYSTEM AND METHOD CONSIDERING DRIVING ENVIRONMENT, CAPABLE OF AUTOMATICALLY CONTROLLING AN INTER-CAR DISTANCE ESPECIALLY WHEN IT IS RAINY OR DARK) introduces the use o...

Problems solved by technology

[0003] However, at this stage, it is still far from realizing the full sense of road active safety.

First of all, on-board radars and cameras are mainly used to detect vehicles in the front and rear directions. For obstacles that are far away in the left and right directions, or within the blind spot of the driver's vision, or high-speed small motor vehicles that are blocked by obstacles, it is impossible to raise an alarm in advance.

Secondly, the active safety control system is expensive and is currently only applied to high-end models. For ordinary family cars, which account for the largest proportion of road vehicles, this function cannot be realized.

Third, mini-cars, motorcycles and pedestrians on the road cannot enjoy the safety and comfort brought by active safety technology

However, although these related vehicle components have made great progress in technology, in addition to the V2V technology itself, the popularity of the technology is also a very important factor. If it cannot be popularized, it will not be able to play the expected role at all.
