High-speed vehicle safety early warning method and system based on inner wheel difference

Abstract

The invention discloses an automobile high-speed driving safety early warning method and system based on inner wheel difference. The system comprises risk data acquisition, risk identification, risk evaluation and risk early warning. According to the risk data acquisition, road environment, vehicle operation data, OBD data and vehicle original data are acquired. According to the risk identification, the risk source of the inner wheel difference and the characteristics of the risk source in the turning driving process of an automobile are identified; the risk value RAi of the risk source Ai isevaluated according to an automobile turning driving inner wheel difference risk source database. According to the risk evaluation, the overall risk level of the inner wheel difference is evaluated. According to the risk early warning, an early warning method is provided for a driver according to the total risk level of the inner wheel difference, and the risk can be reduced, eliminated or controlled. Overall safety risk management is carried out on the inner wheel difference, traffic accidents caused by various risk sources of the inner wheel difference during the turning driving of the automobile are avoided, and the turning driving safety of the automobile is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile driving safety risk management, and in particular relates to a method and system for early warning of automobile high-speed driving safety based on inner wheel difference. Background technique [0002] In recent years, with the sustained and rapid development of the world economy, the number of motor vehicles has increased rapidly. By the end of 2019, the number of motor vehicles in the world has reached 1.29 billion (348 million in China), and 1.25 million people die in car accidents every year (6.3 million in China). million), the road traffic safety situation is very severe. During the driving process of a car, dangerous road conditions, poor vehicle technical performance and out-of-control driving will all cause car accidents, which are as difficult to prevent as sudden mine disasters and floods, making motor vehicle safety the first priority of traffic accidents "Killer", all countries in...

AI Technical Summary

Problems solved by technology

[0005] At present, the monitoring and alarming of the inner wheel difference only involves the individual parameters of the distance of obstacles located in the inner wheel difference area, and cannot reflect all risk sources of the inner wheel difference. Carry out safety risk management methods such as safety identification, assessment, early warning, and control, so that it is impossible to determine the overall risk level of the inner wheel differential, the main risk factors, control indicators and the control range, making it difficult to provide early warning to the driver based on the overall risk level of the inner wheel differential The method reduces, eliminates or controls the risk of inner wheel difference to ensure the driving safety of the car when turning
