Vehicle rollover prevention device and rollover prevention method by using gyroscope rotational inertia

Abstract

The invention discloses a vehicle rollover prevention device by using gyroscope rotational inertia. The vehicle rollover prevention device is composed of a plurality of concentric rotational inertia gyroscopes which rotate in different directions and are connected to a vehicle body through a balance force supplying device. A chassis lattice arrangement range sensor collects the real-time distance information of the distance of all point locations to the ground, and 360-degree included angels in all the directions of the axial direction of the gyroscopes and the vehicle body are adjusted timely. The vehicle rollover prevention device further discloses a vehicle rollover prevention method by using the gyroscope rotational inertia. When side collision accidents happen to the vehicle body, or the vehicle turns a corner at an over speed, or the vehicle travels to cross a large street at a lateral tilting angle, rollover of the vehicle body is avoided.

Description

technical field [0001] The invention belongs to the field of vehicles, in particular to an anti-rollover device. Background technique [0002] In recent years, in some traffic accidents, due to the increase in vehicle speed and the fact that the driver did not feel specific signs when the vehicle rolled over, the vehicle rollover accident caused greater damage, which in turn led to a significant increase in the casualty rate; some Cars with a high center of gravity will overturn due to excessively high turning speeds; high-speed trains need to decelerate due to centrifugal force when turning, otherwise the risk of derailment will increase; there are tens of millions of off-road vehicles and hundreds of millions of users. The working conditions are harsh, and when the vehicle is working on a slope, especially when the vehicle is loaded, the center of gravity moves up, the stability of the vehicle decreases, and the vehicle may roll over, causing casualties.

[0002] In recent years, in some traffic accidents, due to the increase in vehicle speed and the fact that the driver did not feel specific signs when the vehicle rolled over, the vehicle rollover accident caused greater damage, which in turn led to a significant increase in the casualty rate; some Cars with a high center of gravity will overturn due to excessively high turning speeds; high-speed trains need to decelerate due to centrifugal force when turning, otherwise the risk of derailment will increase; there are tens of millions of off-road vehicles and hundreds of millions of users. The working conditions are harsh, and when the vehicle is working on a slope, especially when the vehicle is loaded, the center of gravity moves upward, the stability of the vehicle decreases, and the vehicle may roll over, causing casualties

[0003] At present, the commonly used method to prevent vehicle rollover is to apply brakes to the wheels on the outside of the turning vehicle, and the resulting yaw moment offsets the centrifugal force generated by part of the vehicle's turning, which reduces the probability of vehicle rollover, which is especially important for cars with a low center of gravity. Anti-rollover is very effective, but for large passenger cars with high center of gravity, heavy load and high speed, especially trucks with high center of gravity and heavy load, the anti-rollover effect of engineering vehicles is not very ideal
