Background
When trucks are turned right, particularly engineering vehicles, muck transport vehicles, dump trucks and the like which are operated in urban areas, traffic accidents that road users such as pedestrians, non-motor vehicles and the like are collided are often caused.
The so-called inner wheel difference is the difference between the turning radius of the inner front wheel and the turning radius of the inner rear wheel when the vehicle turns, and for a large vehicle, the difference can cause the moving tracks of the front wheel and the rear wheel to be misaligned when the vehicle turns, which means that the front wheel avoids pedestrians and non-motor vehicles when a driver turns a steering wheel, but the rear wheel does not necessarily avoid the front wheel, thereby causing accidents.
In fact, many pedestrians or electric vehicles in accidents are tightly attached to the vehicle body, and are dragged into the vehicle by the rear vehicle body when the vehicle turns, and crush the vehicle to death, and the visual blind area of the right turn of the truck is caused by that a driver sits on the driver seat on the left side and only observes the right rear side by the rearview mirror, so that the visual range is limited. Rather than a motor vehicle that is short and the driver may not see them at all. The non-motor vehicles or pedestrians walk into the range of the blind vision area of the inner wheel to face danger, and the intersection where the truck turns right is often the area where the pedestrians and the non-motor vehicles intensively wait. Once a traffic accident happens when the truck turns right, the truck is usually injured immediately after non-death.
According to incomplete statistics, the traffic accident caused by the right turn of the large vehicle is 1/8 of the total case of the accident, which also means that the problems caused by the blind area, the 'inner wheel difference' and the like involved in the right turn of the truck need to be reasonably solved.
Aiming at the problems, the dead zone and the 'inner wheel difference' of the right turn of the truck bring great potential safety hazards to pedestrians and riders, great psychological burden is also brought to truck drivers, and a safety prompting device for the right turn of the load truck is urgently needed to be developed.
