Description

Safety assistance warning system and method

The present invention is a safety auxiliary warning system and method with real-time active warning for personnel, and is particularly related to a vehicle rear-end collision warning system and method with real-time active warning function and improved rear-end collision warning distance.

With the increase in the number of cars, the probability of traffic accidents on highways is also increasing. When a car breaks down temporarily or a traffic accident occurs, in order to avoid rear-end collisions with vehicles behind, the driver will place a tripod warning sign 20 behind the accident scene to remind the rear vehicles to avoid in time, as shown in the first figure. Traffic police often deal with traffic accidents on highways and are a highly dangerous group. There have been news reports of police officers being injured or killed due to negligence in traffic accidents and rear-end collisions with police cars 10.

The current tripod warning sign needs to be carried by the driver and placed at a certain distance behind the vehicle. On the highway, vehicles travel at high speeds and the traffic volume is also large. Drivers carrying warning signs walking on the roadside and running back and forth behind the vehicle are highly dangerous to the driver. Once a collision occurs, it is easy to endanger the lives of the drivers.

There are two problems with this prior art: First, the learning warning sign is only portable. When the driver manually places the learning warning sign, it may be dangerous to walk on the shoulder of the road or behind the vehicle, or the warning safety distance of the learning warning sign may not be far enough. Please refer to the example in the first figure. The setting of the warning sign on the highway is usually 30~50 meters behind the accident scene. Assuming that the rear vehicle 30 is traveling at a speed of 100km/hr (approximately 27.78m/s), when the driver of the rear vehicle 30 fails to brake in advance, the driver only has 1.8 seconds to react and brake at a distance of 50 meters. 50 (meters)/27.78 (meters/second) = 1.8 (seconds). The second is that the learning warning sign does not have the active detection warning function. After the learning warning sign is placed, the police are busy handling the accident scene and have no time to pay attention to the fast approaching vehicles from behind, which will lead to casualties. Therefore, in the above example, the rear vehicle 30 is approaching at a speed of 100km/hr, and the police handling the accident only have 1.8 seconds to react and avoid the rear-end collision of vehicle 30.

In addition, it is known that the central locking system for a vehicle includes a remote control and a vehicle host. Although the vehicle host can be remotely unlocked by the remote control to facilitate passengers or drivers to get on and off the vehicle, the vehicle host does not have a warning function for rear-end collisions, and the remote control is only a portable controller and does not have any warning notification function. Therefore, the safety auxiliary warning system and method of the present invention endows the vehicle host with a vehicle rear-end collision warning function, which enables unlocking a door and sounding the vehicle horn, which will help passengers in the car to respond to the situation of the rear vehicle approaching quickly, and facilitate passengers to quickly get out of the car and escape, and enable the warning notification function of the portable remote control, so that the person wearing the remote control can get a warning.

Warning devices such as warning poles, warning cones, and warning signs are widely used and are often used to establish a working range or a warning range to prevent outsiders from entering the range. However, it is known that warning devices do not have any detection and sensing functions, resulting in the personnel in such ranges being unable to be notified of outsiders entering the range or being unable to detect that the equipment has been moved or knocked down, and thus being unable to establish the range.

The present invention aims to solve the above four problems: (1) the learning warning device is only portable, which may cause danger to personnel walking on the shoulder of the road when manually placing the learning warning device, or the safety distance of personnel placing the warning device is not far enough; (2) the learning warning device does not have the early warning function of active detection, which means that after placing the learning warning device, the police will be busy dealing with the accident scene and have no time to pay attention to the rear at all times. (3) Learning that the central locking system of the vehicle does not have a warning function for rear-end collisions, which makes it impossible for passengers in the car to quickly get out of the car and escape when the rear vehicle approaches quickly; and (4) Learning that warning devices such as warning poles, warning cones, and warning signs do not have detection and sensing functions, which results in the warning range established by such warning devices being invaded and the people within the range cannot be notified. The present invention provides a safety auxiliary warning system, which uses a remote control to remotely control the forward direction of a warning device with a remote control movement function through a vehicle host, so as to avoid people walking on the shoulder of the road with the warning device, and increase the safety distance of the warning device. When the warning device is to be retrieved, the warning device is remotely controlled to return to the starting position through the vehicle host by the remote control, without the need for people to retrieve the warning device; and, using the warning device with the oncoming vehicle distance measurement function and the collision sensing function, a warning signal is sent to the vehicle host to unlock the car door and enable the car horn to sound and the warning notification function of the portable remote control, so as to remind nearby people to dodge the rear-end collision of the vehicle to avoid personal injury.

The controller 232 of the vehicle host 230 receives the mobile notification signal from the host-side communication module 231, and starts waiting to receive a flashing indication signal transmitted by the warning device 220 in response to the mobile notification signal. The processing module 221 wirelessly transmits the flashing indication signal to the vehicle host 230 every 1 second in the mobile mode. The controller 232 of the vehicle host 230 receives the flashing indication signal from the host-side communication module 231 each time, and enables the turn signal line 46 to flash the turn signal once in response to the flashing indication signal. The direction lights of the car 210 continue to flash, which can remind people not to take the warning device 220 out of the communication range of the car host 230, and at the same time remind distant vehicles to slow down to ensure the safety of people.

In one embodiment, the processing module 221 continuously receives the distance signal of each ranging from the ranging module 222. When the processing module 221 determines that the distance difference represented by the two distance signals generated by two consecutive ranging exceeds a distance threshold, or the distance value represented by the distance signal is less than a warning distance threshold, the processing module 221 decides to generate the warning signal. In another embodiment, the processing module 221 continuously receives the distance signal and time of each ranging from the ranging module 222. The processing module 221 calculates the time difference and distance difference between the two distance signals generated by two consecutive ranging, and calculates the distance difference divided by the time difference to obtain a speed value. If the processing module 221 determines that the speed value exceeds a speed threshold value, the processing module 221 decides to generate the warning signal.
