Description

Vehicle collision warning system and method

Technical field

The invention is a collision early warning system, in particular to a vehicle collision early warning system and method which has an instant active early warning indication and improves the collision early warning distance.

Background technique

With the increase in the number of cars, the probability of traffic accidents on the highway is also increasing. When the car has a temporary failure or a traffic accident, in order to avoid the rear vehicle collision, the driver will place a tripod warning sign 20 behind the accident scene to remind the rear vehicle to avoid in time, as shown in the schematic diagram in FIG. 1. Traffic police often deal with traffic accidents on highways and belong to a high-risk group. There have been news reports that they chased police cars 10 due to oversight of traffic accidents, resulting in casualties.

The current tripod warning sign requires the driver to carry it and walk to the rear of the vehicle at a distance. Due to the high speed and high traffic flow on the highway, the driver walks on the shoulder with a warning sign and runs back and forth behind the vehicle, which is highly dangerous to the driver. Once a collision accident occurs, it is easy to endanger People's lives.

There are two problems with this prior art: One is that the prior art warning signs are only portable. When the driver manually places the prior art warning signs, it may be dangerous to walk on the shoulder or walk behind the vehicle, or the existing The warning safety distance of the technical warning sign placement position may not be far enough. Please refer to the example shown in Figure 1. The setting of warning signs on the highway is usually only 30 to 50 meters behind the accident scene. It is assumed that the rear vehicle 30 travels at a speed of 100km/hr (approximately 27.78m/s). When the rear vehicle 30 The driver's oversight didn't brake in advance. The distance of 50 meters only had a reaction time of 1.8 seconds to the driver. 50 (meter)/27.78 (meter/second) = 1.8 (second). The second is that the warning sign of the prior art does not have an early warning function for active detection. After placing the warning sign of the prior art, the police officer is busy dealing with the scene of the accident and has no time to pay attention to the rapid approach of the rear vehicle at any time, which will cause casualties. Therefore, in the foregoing example, the rear vehicle 30 approaches quickly at a speed of 100 km/hr, and the police officer handling the accident has a reaction time of only 1.8 seconds to evade the collision of the vehicle 30.

In addition, the prior art vehicle central locking system includes a remote controller and a vehicle host. Although the vehicle host can be remotely unlocked by the remote controller to unlock a door, it is only for the convenience of passengers or driving, but the vehicle The host does not have the early warning function of car collision. Therefore, the present invention gives the vehicle mainframe an early warning function for car collision, to enable unlocking a door and enable the car horn to sound, which will help the passengers in the car to respond to the rapid approach of the vehicle in the rear, and facilitate the passengers to quickly Get out of the car and escape.
