Automobile side-turning-preventing device and method based on double-gyro stabilizer

Abstract

The invention discloses an automobile side-turning-preventing device based on a double-gyro stabilizer, further discloses a side-turning-preventing method, and belongs to the field of automobile active safety. A side-turning detecting module, an electronic control unit, a first gyro stabilizer module, a second gyro stabilizer module, a power supply and an alarm are arranged on an automobile, thusthe side-turning detecting module is used for detecting automobile speed signals and side-turning signals, and the electronic control unit is used for judging the traveling state and the side-turningtendency of the automobile. When the automobile has side-turning danger, alarm is sent to a driver through the alarm, meanwhile the first gyro stabilizer module and the second gyro stabilizer module are controlled to work, and the side-turning-resisting torque is output to achieve emergency protection for passengers in the automobile. The defects that an existing side-turning-preventing device iscomplex in structure, low in response speed and not capable of effectively providing enough aligning torque are overcome, the active side-turning-preventing capacity of the automobile is improved, andthe automobile side-turning-preventing device is simple in structure, good in applicability, good in controllability and good in side-turning-preventing property.

Description

technical field [0001] The invention belongs to the field of automobile active safety, and specifically refers to an automobile anti-rollover device and a control method based on double gyro stabilizers. Background technique [0002] Rollover is an important safety problem. Once the vehicle rolls over during driving, the driver often has no time to take effective measures, and the hazard of a rollover accident is fatal. Usually, once the vehicle rolls over, it not only directly threatens the life safety of the occupants in the vehicle, but also may endanger other vehicles and pedestrians on the road, causing serious secondary accidents. Rollover always occurs in a short time, and the anti-rollover device needs to provide a large enough righting moment in a very short time, so the response speed of the anti-rollover device and the size of the righting moment that can be provided are relatively high. Require. [0003] An adaptive anti-rollover device for automobiles (applica...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problems of slow response speed, unsatisfactory effect and complex structure in most existing anti-rollover protection devices and methods, the present invention discloses an automobile anti-rollover device and control method based on double gyro stabilizers

The present invention solves the problem of the response of the existing anti-rollover device through the cooperation between the rollover detection module, the electronic control unit (ECU), the first gyro stabilizer module and the second gyro stabilizer module, the power supply and the alarm. The defects of slow speed and inability to effectively provide a sufficient righting moment improve the vehicle's active anti-rollover capability
