Early warning system and judgment method for heat fade phenomenon of vehicle

Abstract

The invention discloses an early warning system and a judging method for the thermal recession phenomenon of a vehicle, which mainly adopts the combined judgment of braking force + braking time + fixed value + instant temperature + historical average temperature to carry out early warning judgment on the thermal recession phenomenon of the vehicle, After comprehensive consideration and combination, as long as one or several of them are close, it can be determined that thermal recession may be about to occur, and the operation time is reserved for further operations of the driver, and due to different vehicles, different drivers, different road conditions, and different loads , Different wear conditions and different brake materials will more or less affect the change of the thermal attenuation critical value. The early warning value can be dynamically modified to realize the early warning and judgment of the thermal fading phenomenon under different driving conditions. Modify the early warning conditions to make the judgment result more sensitive and reliable.

Description

technical field [0001] The invention relates to the technical field of vehicle heat decay, in particular to an early warning system and a judging method for the phenomenon of vehicle heat decay. Background technique [0002] With the advancement of science and technology and the development of electronic commerce, the transportation industry plays a vital role in people's lives. In the current medium and long-distance transportation, especially in high temperature weather, the temperature of the wheels of trucks rises very obviously. High temperature has a great impact on the wheels. On the one hand, it will cause damage to the wheels and reduce their life. Finally, it will cause serious wear and softening of the brake pads, which will reduce the life and performance of the brake pads. In severe cases, it will cause brake failure and cause serious safety accidents. [0003] Long-term braking of the vehicle will cause the hub or the wheel disc to generate heat due to frictio...

In the current medium and long-distance transportation, especially in high temperature weather, the temperature of the wheels of trucks rises very obviously. High temperature has a great impact on the wheels. On the one hand, it will cause damage to the wheels and reduce their life. Finally, it will also cause serious wear and softening of the brake pads, which will reduce the life and performance of the brake pads. In severe cases, it will cause brake failure and cause serious safety accidents.

[0003] Long-term braking of the vehicle will cause the hub or the wheel disc to generate heat due to friction, and the accumulation of temperature will cause thermal degradation, which greatly affects the braking performance and safety of the vehicle. In the prior art, in order to prevent the thermal degradation of the vehicle, it is mainly Spray water to cool down the wheel hub, and the early warning of the thermal recession of the vehicle either only uses a fixed temperature for detection and judgment, or does not carry out early warning judgments and sprays water to cool the wheel hub all the time. This continuous water spray cooling method will cause The road surface is wet and slippery, which affects the driving of passing vehicles and increases the danger of the road. The early warning judgment method using only fixed temperature detection is not comprehensive, there are few factors to consider, and the probability of vehicle thermal recession is high.
