Method for stopping vehicle downhill neutral sliding

Abstract

The invention relates to the field of driving safety, in particular to a method for stopping vehicle downhill neutral sliding. The method for stopping vehicle downhill neutral sliding, disclosed by the invention, detects a vehicle in real time to obtain a state of the vehicle; and the state includes a state A-a neutral state, a state B-altitude falling, and a state C-vehicle speed increased and higher than a set limit value v. Then, the method judges if the state of the vehicle is the state A or the state B and if the state lasting time exceeds a set limit value t; if so, the warning prompt and / or the brake device triggering are performed; if not, the method judges if the vehicle state is the state A or the state C and if the state lasting time exceeds a set limit value t; if so, the warning prompt and / or the brake device triggering are performed; and if not, the state of the vehicle is continuously detected. The method can prevent the vehicle downhill neutral sliding, so that the generation of dangers is prevented, the driving safety is improved, the method is simple and feasible, and the cost is low.

Description

technical field [0001] The invention belongs to the field of driving safety, and in particular relates to a method for preventing a vehicle from sliding downhill in neutral. Background technique [0002] With the development of society and the improvement of people's living standards, more and more people own cars, and the increase in the number of cars has also led to an increase in traffic accidents, which have brought great harm and loss to families and society. Traffic accidents are caused by bad driving behaviors of drivers, such as overloading, speeding, frequent lane changes, fatigue driving and neutral sliding. [0003] Among them, sliding in neutral gear is very harmful. First of all, when the car is coasting in neutral gear, the air compressor does not work because the engine stops running, and the car needs to be braked frequently, and the compressed air in the air storage tank is continuously reduced, so sliding in neutral gear is dangerous. It may cause the bra...

[0003] Among them, sliding in neutral gear is very harmful. First of all, when the car is coasting in neutral gear, the air compressor does not work because the engine stops running, and the car needs to be braked frequently, and the compressed air in the air storage tank is continuously reduced, so sliding in neutral gear is dangerous. It may cause the brakes of the car to fail; secondly, it is easy to damage the transmission. Since a large number of rolling bearings are used in the transmission, although the second shaft of the transmission rotates when gliding in neutral, the constant meshing gears do not rotate, so these gears cannot stir the gear oil in the transmission. The bearings ( Especially the bearings with high position and splash lubrication) cannot be reliably lubricated, so the bearings and gears will wear prematurely

[0004] For this reason, sliding in neutral gear when going downhill has been confirmed as a serious bad driving behavior and an important cause of downhill accidents, but there are still some drivers who have weak safety awareness. Usually this kind of behavior can only be regulated by the driver himself, and has a low binding force, so it is necessary to automatically detect and prevent this behavior to reduce the occurrence of accidents
