Description

Blind area warning system suitable for vehicle turns

Technical Field

The utility model relates to the technical field of automobiles, in particular to a blind area warning system for a large-sized vehicle.

Background

When a large truck turns right, the blind area of the right visual field is very large, the condition of the right side of the vehicle cannot be basically seen, and a motor vehicle or a non-motor vehicle running on the right side of the truck is often involved under the wheels due to the internal wheel difference, so that the large truck brings great risks to running and related vehicles; in order to reduce the risk, the large truck is stopped for a period of time when turning right, and after the truck is stopped, the condition of the right rear of the vehicle can be better observed, the vehicle running on the right side can be awakened, and the safety of pedestrians on the non-motor vehicle on the right side can be protected, so that many freight transportation companies can stipulate that the large truck must stop for 5 seconds when turning right and then start to run.

However, the above-mentioned means of stopping, for the large truck to travel, especially on the route that needs frequent right turn, will greatly reduce the efficiency of the same row, and for the vehicle that follows behind the large truck, once it is unclear what the large truck must stop turning right, it is easy to hit the truck without any warning; even if the vehicle has a right turn signal lamp, the danger can occur due to the fact that the speed of a rear vehicle or a side vehicle is high, the safety distance is not kept, and the condition of the road is not noticed, and the driving or pedestrian is required to actively observe; the road condition is checked by opening the camera when turning right, so that a truck driver is required to obtain road condition information from the multimedia actively through distraction; and the mode of adopting alarm and whistle can frequently cause noise pollution again. In addition, various sensors are additionally arranged on the vehicle body to sense the distance between the object beside the vehicle and the vehicle in the prior art, but the system usually needs complex system support due to the need of identifying the type and the approaching intention of the object, otherwise, misjudgment is easily caused, and in some prior art, the system is connected with a power system and a brake system, and even the running risk is increased under the condition of misjudgment.
