Description

Vehicle safety warning system device and method thereof

The invention relates to a vehicle safety warning system and a method thereof. The utility model is applied to a large vehicle, and the device uses the control unit as a control area network transmission bus (CAN) (Controller Area Network) Bus to be connected to the vehicle body. The safety warning system can achieve a significant increase in driving safety and reduce the need for accidental regrets.

At present, the conventional large-scale vehicles are generally equipped with turning warning buzzers and vehicle-side driving records for many years. However, in the past, news reports often show large buses, which often occur when pedestrians cross the corner. Or the accident of a motorcycle locomotive collision or even a human life.

The shortcomings of traditional large vehicles are as follows:

First, the large-scale vehicle has a large arc and a lot of dead angles. The rear mirror cannot cover the entire range.

Second, pedestrians are not alert enough to the arcing range of large vehicles, even ignoring the sound of buzzers.

Third, the steam locomotive is not enough to warn large vehicles in turning, and parallel with large vehicles.

Fourth, the car's driving record photography fixed also has its dead angle, the driver can not detect at the right time.

5. The driver cannot fully grasp the turning range.

Therefore, how to solve the problem that the conventional traditional large-scale vehicle safety warning effect of such a conventional practitioner is not completely difficult to use is a problem to be solved.

In view of the shortcomings caused by the above-mentioned prior art, the main purpose of a vehicle safety warning system device and method thereof is to have an active reminding function in normal times, and to provide two-way reminding for driving and using passers-by instead of a single pair as in the prior art. Driving or reminding by passers-by, and it is a reminder effect with different levels and levels.

Another object of the vehicle safety warning system device and method thereof is to not only remind pedestrians and motor vehicles, large vehicles to turn within the risk range of the wheel and the tire movement, so that pedestrians and steam locomotives can be avoided in advance, and can be informed Whether the driver is in the corner and whether there are obstacles including pedestrians.

To achieve the above and other objects, the present invention provides a vehicle safety warning system apparatus and method thereof, which are suitable for use in a large vehicle.
