Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] see Figure 1-3 , the present invention provides a technical solution: a vehicle anti-rollover control method based on the Internet of Vehicles, comprising the following steps:

[0030] A. During the operation of the vehicle, the vehicle's yaw rate, roll rate, and pitch rate are integrated to obtain the real-time roll angle;

[0031] B. After that, the collected real-time roll angle will be processed by Kalman filter for data fusion processing to obtai...

Abstract

The invention discloses a vehicle anti-rollover control method based on Internet of Vehicles. The vehicle anti-rollover control method comprises the following steps of A, performing attitude integration on yaw angular speed, rollover angular speed and pitch angular speed of a vehicle in the vehicle running process, so as to obtain a real-time rollover angle; B, performing data integration on a signal by a Kalman filter according to the acquired real-time rollover angle, so as to obtain the real-time optimum value of the rollover angle of the vehicle; C, after the optimum value of the vehicle attitude is obtained, calculating the rollover judgment feature value by a load LTR (transverse transfer rate) calculation formula according to the lateral acceleration; D, judging whether the rolloverdanger occurs or not; when the rollover danger does not occur, predicting the rollover judgment feature value within 1 to 2s by a multi-layer hierarchical modeling predicting method, so as to obtainthe 1-2s predicting value of the rollover judgment feature value; further judging whether the rollover accident risk occurs within 1 to 2s or not in future. The vehicle anti-rollover control method can be used for predicting the future rollover movement of the vehicle, and meeting requirement of early warning on rollover.

Description

technical field [0001] The invention relates to the technical field of vehicle anti-rollover control, in particular to a vehicle anti-rollover control method based on Internet of Vehicles. Background technique [0002] The Internet of Vehicles is an interactive network that integrates a variety of advanced technologies and advanced equipment. The network can complete the collection of its own status information and external environment information through different vehicle equipment; The information is transmitted and aggregated to the data center; finally, the information collected by these vehicles is analyzed and processed through computer technology; the Internet of Vehicles system consists of a data center control platform, an Internet of Vehicles vehicle terminal system, and a wireless communication system. [0003] Vehicle rollover is a high-incidence and dangerous traffic accident. Rollover is defined as any kind of manipulation that can make the vehicle rotate aroun...
