Multi-condition vehicle rollover index calculation device and calculation method thereof

Abstract

The invention discloses a multi-condition vehicle rollover index calculation device and a calculation method thereof. The device comprises a rollover index calculation unit, an electronic gyroscope sensor, a vehicle angular acceleration sensor, a left-front relative displacement sensor, a left-front unsprung mass acceleration sensor, a right-front relative displacement sensor, a right-front unsprung mass acceleration sensor, a left-rear relative displacement sensor, a left-rear unsprung mass acceleration sensor, a right-rear unsprung mass acceleration sensor and a right-rear relative displacement sensor. When the device works, the rollover index calculation unit is used for calculating rollover factors through data collected by the sensors according to a vehicle rollover dynamic law and evaluating the vehicle rollover risk. The device can be used for calculating the vehicle rollover risk under multiple conditions, provides the calculation result to drivers or other safety control devices, so that vehicle rollover can be effectively controlled and prevented.

Description

technical field [0001] The invention relates to the field of vehicle rollover safety, in particular to a vehicle safety evaluation device and method, in particular to a multi-working-condition vehicle rollover index calculation device and a calculation method thereof. Background technique [0002] As consumers pay more and more attention to vehicle safety, vehicle safety measures are constantly being produced and improved. Vehicle rollover accidents account for a relatively low proportion of traffic accidents, but the casualty rate is high. Especially for large passenger cars and trucks, it is more likely to cause mass casualties and injuries and affect other vehicles on the road surface. The simple and accurate calculation device and method for vehicle rollover index will help the application of vehicle rollover prevention means and achieve better rollover prevention effect. [0003] After searching relevant documents, there are many patents discussing the design of the v...
