Abstract

A vehicle turning warning system capable of indicating an inner wheel difference warning range is mainly applicable to a vehicle. When the vehicle turns, a control module captures turning information of the vehicle computer for processing, then outputs a control signal to drive a first rotating device disposed on the right side of the vehicle to rotate to a corresponding angle, and controls a first light source indicator to emit an illumination source to indicate an inner wheel difference warning range when the vehicle turns right; or controls a second rotating device disposed on the left side of the vehicle to rotate to a corresponding angle, and controls a second light source indicator to emit an illumination source to indicate an inner wheel difference warning range when the vehicle turns left.

Description

Vehicle turning warning system capable of indicating the inner wheel differential warning range

The invention relates to a warning system, in particular to a vehicle turning warning system capable of indicating an inner wheel differential warning range.

When the vehicle is driving on the road and wants to turn, the inner wheel of the vehicle will be biased inward due to the difference of the inner wheel, and it is easy to be forced to the side of the passerby, which is dangerous. Among them, especially the cement truck and the junction car. Large vehicles such as buses or buses have the largest internal wheel difference, so driving often fails to pay attention to the inside of the vehicle body, which is likely to cause traffic accidents to the nearby passers-by. The so-called inner wheel difference refers to the difference caused by the trajectory of the front and rear wheels when the vehicle is turning. When the vehicle turns, the inner rear wheel will be biased inward, and the distance between the offset trajectory and the front wheel trajectory is called Make the inner wheel difference.

In order to avoid traffic accidents caused by internal wheel differentials, the Ministry of Communications requires large vehicles to be equipped with turning and reversing warning devices to alert other passers-by through warning sounds. Although there are turning and reversing warning devices, there are many environmental noises on the general roads, which makes it difficult for the passers-by to hear or easily misjudge the warning sounds, which makes the regrets still easy.

Another example is the "I584979" patent (hereinafter referred to as the previous case) of the Republic of China Announcement, which discloses a car blind zone monitoring and early warning system, including a warning module, an obstacle detector, a processing device and an adjustment module.

The processing device is configured to activate an alert module alarm when receiving an obstacle detection signal. The adjustment module is configured to detect a turning angle of the automobile, and adjust a size of a detection range of the obstacle detector according to a turning angle of the automobile.

Although the previous case revealed that when the obstacle is detected or broke into the detection range, the warning module sends an alarm to alert the driver, but the speed of the vehicle traveling on the road is fast, and the moving speed of the obstacle is different, resulting in the driver not being able to react immediately. , so that regrets are still easy to happen.
