Abstract

The invention provides a brake failure early warning method and device for load-carrying vehicles, electronic equipment and a storage medium. The method comprises the steps that vehicle surrounding environments and road environment data of the load-carrying vehicles and vehicle state and driving action data of the load-carrying vehicles are acquired; Extracting multiple types of feature information according to the surrounding environment and road environment data of the vehicle and the vehicle state and driving action data of the vehicle; Establishing and training a hidden Markov model for predicting the braking state according to the extracted multiple types of feature information; Using the real-time vehicle surrounding environment and road environment data of the to-be-predicted load-carrying vehicle and the real-time vehicle state and driving action data of the to-be-predicted load-carrying vehicle as input of a hidden Markov model; Determining the brake state of the to-be-predicted load-carrying vehicle according to the hidden Markov model; If the brake state of the to-be-predicted load-carrying vehicle is a quasi-failure state, alarm information is generated; And if the brake state of the to-be-predicted load-carrying vehicle is a failure state, planning a safety path. The method and the device provided by the invention realize brake failure early warning.

Description

technical field [0001] The invention relates to the field of vehicle early warning, in particular to a vehicle brake failure early warning method, device, electronic equipment, and storage medium. Background technique [0002] In recent years, with the development of the logistics industry, the freight turnover of China's highways is far ahead of the sum of other modes of transportation. Statistics show that by the end of 2016, there were more than 13 million trucks nationwide. At present, the total number of traffic accidents in my country is still high every year, and trucks cause about one-third of the traffic accident deaths. According to research, among numerous traffic accidents, rear-end collisions account for more than 70% of the total accident rate, especially on expressways, where there are more rear-end collisions, frequent severe accidents, and greater loss of personnel and property. serious. When driving at high speed, when the driver lacks routine maintenanc...
