Car rollover time measuring device and car rollover time calculation method

Abstract

The invention relates to a car rollover time measuring device and a car rollover time calculation method. Aiming at defects of the existing car rollover prediction research, the invention provides a car rollover time measuring device, which comprises a left front wheel vertical load sensor, a calculation unit, a right front wheel vertical load sensor, a right rear wheel vertical load sensor, a left rear wheel vertical load sensor, a car body and the like. The invention also provides the car rollover time calculation method. By using the invention, the rollover time in a car driving process can be calculated according to vertical loads of respective wheels of a car, so a vehicle-mounted control system or a driver can adjust a car driving state before the car is rolled over, and rollover accidents of the car can be prevented.

Description

technical field

[0001] The invention relates to the technical field of vehicle rollover and rollover research, in particular to a vehicle rollover time measuring device and a calculation method thereof. Background technique

[0002] Predicting vehicle rollover in advance plays a very important role in preventing traffic accidents. However, in the current research on vehicle rollover prediction and early warning, the vehicle rollover prediction is mainly carried out by detecting whether the vehicle's rollover evaluation index reaches the set static threshold. When it is detected that the rollover evaluation index has reached the rollover threshold, the car has already started Rollover, at this time, the driver makes corresponding operations to correct the driving state of the car, which often has hysteresis, and the anti-rollover effect is not ideal. A small number of researchers have proposed that if the car maintains the current driving state, by observing the time when th...
