Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] The invention provides a vehicle rollover prevention method based on a control moment gyro, which relates to a vehicle using a control moment gyro, and can be widely used in the active anti-rollover control technology of the vehicle. The vehicle includes a control solver system, a measurement device, a control moment gyro and four control moment gyros. When the vehicle turns or is stimulated by external disturbances, the measuring device detects the response of the vehicle, estimates the state of the vehicle, and controls the torque gyro to generate a torque of several thousand N·m, which is used to maintain the balance of the vehicle body and make the vehicle even collide under any circumstances. The situation will not be overturned. As the executive component of the vehicle attitude system, the control moment gyroscope works on the principle of form...

Abstract

The invention relates to the field of vehicle rollover prevention, in particular to a vehicle anti-rollover method based on a control moment gyroscope. When a vehicle turns or is under external interference stimulation, a measurement device detects the response of the vehicle, the own suspension mechanism dynamics of the vehicle can be combined to estimate the state of the vehicle through a vehicle rollover model, the control moment gyroscope generates torques of thousands of N.m for keeping the balance of a vehicle body, and therefore, the vehicle is free from rollover under any situation even under a collision situation. A rollover judgment system can accurately estimate the tilt state of the vehicle so as to judge vehicle rollover. Meanwhile, the own mechanism characteristics of the vehicle are fully considered. Through a continuous anti-rollover moment output by the control moment gyroscope, the vehicle is free from rollover under any situation even under the collision situation, and a corresponding control algorithm can guarantee singularity avoidance and accurate moment output.

Description

technical field [0001] The invention relates to the field of anti-rollover of vehicles, in particular to a method for anti-rollover of vehicles based on a control moment gyroscope. Background technique [0002] Along with the rapid increase of the total mileage of highways and the total amount of road passenger transportation in my country, the role of large passenger vehicles in road transportation is becoming more and more prominent. Due to the large passenger capacity of passenger vehicles, rollover will cause greater casualties, and the social impact is relatively bad. The rollover safety of passenger vehicles has become the focus of attention of the whole society. It is of great practical significance to study how to improve the rollover stability of large vehicles. [0003] Anti-rollover stabilization measures for automobiles mainly include suspension components, active anti-rollover levers, brake force adjustment, hydraulic devices, and active steering. high.
