Vehicle rollover prevention control system and rollover prevention control method

Abstract

The invention relates to the field of vehicle rollover prevention, and discloses a vehicle rollover prevention control system and a rollover prevention control method. The vehicle rollover preventioncontrol system comprises a main controller, a suspension system and a braking system, wherein the vehicle is a full trailer or a semi-trailer or a middle axle trailer or a tractor or a truck or a light truck or a passenger car or a rail vehicle, the control system further comprises a wheel speed acquisition module, a suspension load acquisition module, a lateral acceleration acquisition module anda vehicle body inclination acquisition module, the wheel speed acquisition module, the suspension load acquisition module, the lateral acceleration acquisition module and the vehicle body inclinationacquisition module are electrically connected with the main controller, and the main controller performs rollover prevention adjustment on the suspension system and the braking system according to signals transmitted by the acquisition wheel speed acquisition module, the suspension load acquisition module, the lateral acceleration acquisition module and the vehicle body inclination acquisition module. According to the control system, weighted fusion is carried out through a plurality of parameters to obtain a reliable and timely rollover trend, so that an accurate and timely anti-rollover suggestion and an anti-rollover strategy are provided for a user, the user experience is better, and the situation that driving of a driver is interfered due to too early or too late appearance of the suggestion.

Description

technical field [0001] The invention relates to the field of vehicle rollover prevention, in particular to a vehicle rollover prevention control system and an anti-rollover control method. Background technique [0002] Due to the large mass and high center of gravity of heavy-duty vehicles, especially heavy-duty trailers, if the vehicle speed or steering is not properly controlled when driving on a curve, it is relatively prone to rollover, which is a major cause of traffic accidents. The current method and device for vehicle roll stability control (Roll Stability Control, RSC) are mainly based on the lateral acceleration of the vehicle or the load transfer rate of the wheels on both sides of the vehicle to monitor the rollover tendency of the vehicle, and when the above monitoring signal exceeds the When the threshold is exceeded, a warning or brake intervention is performed. For braking intervention, the well-known technology also includes rollover test braking, that is, ...

Problems solved by technology

There is often a paradox in the timing of the above-mentioned intervention measures: premature braking intervention, especially the test braking in the known technology, will affect the normal running of the vehicle and even disturb the driver's judgment on the vehicle state, while too late braking intervention will It may not work at all, because at this time the driver may have judged that the vehicle is driving abnormally and took corresponding steering or braking measures, or it is too late to avoid the vehicle rollover
