Vehicle rollover prediction method, device and equipment

Abstract

The present application is applicable to the technical field of vehicle safety control, and provides a vehicle rollover prediction method, device and equipment. The method includes the steps: determining a change of a horizontal attitude angle of the vehicle in a first preset period of time based on output data of a gyroscope and three sensitive axes of an inertial sensor mount on the vehicle in afirst preset period of time after the vehicle is started; determining a specific force output change on three sensitive axes of the accelerometer in a first preset period of time based on output specific force data of the accelerometer in the inertial sensor in a first preset period of time if the change in the horizontal attitude angle of the vehicle exceeds a preset horizontal attitude angle change threshold; and if it is determined that the gravity sensitive axis data of the accelerometer is changed in the first preset time period according to the change of the specific force output on thethree sensitive axes of the accelerometer, the vehicle is judged to be at risk of rollover. The vehicle rollover prediction method, device and equipment have the advantages that the judging process is simple; the vehicle is not easy to be disturbed by the external environment; the judging result is accurate; and the vehicle rollover prediction method, device and equipment are suitable for application.

Description

technical field [0001] The present application belongs to the technical field of vehicle safety control, and in particular relates to a vehicle rollover prediction method, device and equipment. Background technique [0002] With the development of expressways in our country, the road transportation industry with multi-style motor vehicles as the carrier ushered in a vigorous development. At the same time, when a motor vehicle is running at high speed, especially when the load is too heavy, the turn is too fast, or the vehicle breaks down, dangerous conditions such as rollover are prone to occur, and the number of traffic accidents caused by this has been high. The stability and safety of the road have become a bottleneck restricting the development of road transportation. Rollover is one of the most serious accidents that threaten the safety of members during the driving of the vehicle. [0003] The research on vehicle rollover warning system and anti-rollover control has ...

Problems solved by technology

[0003] The research on vehicle rollover warning system and anti-rollover control has become a hot topic of domestic and foreign automobile assembly manufacturers, automotive electronics manufacturers, and relevant scholars. Among them, the prediction of rollover time TTR and time based on the vehicle rollover model Variable interactive Kalman filter and other vehicle rollover warning systems, due to the high complexity of prediction and filter update algorithms, the accuracy restricts its practicability and economy

However, the vehicle rollover warning system based on sensors such as laser emitters, ultrasonic ranging, and charge-coupled device CCD cameras is extremely susceptible to interference from the external environment (light intensity, camera shake, road bumps, obstacles), causing the rollover warning system to malfunction. sentence
