Embodiment Construction

[0100] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0101] The present invention provides an anti-rollover active control method based on vehicle chassis integrated control technology, such as Figure 7 As shown, first, determine the control input variables corresponding to the vehicle chassis integrated control system, as well as the state variables and output variables related to vehicle rollover, establish the corresponding vehicle state matrix X and output variable matrix Y, and calculate the state variables The corresponding relative entropy value.

[0102] Secondly, calculate the vehicle state matrix X=[x 1 ,x 2 ,x 3 ,x 4 ,x 5 ,x 6 ,x 7 ,x 8 ,x 9 ,x 10 ,x 11 ] T and the output variable matrix Y=[y 1 ,y 2 ,y 3 ,y 4 ,y 5 ] T The corresponding limit value matrix M a (X) and M i (Y). At the same time, calculate the limit value matrix D corresponding to the relative entropy value of ma...

Abstract

The invention discloses an anti-rollover active control method based on a vehicle chassis integrated control technology. The anti-rollover active control method comprises the steps: 1, forming vehiclechassis subsystems in a coupling mode, and selecting system state parameters; 2, calculating an abnormal value rate of an output variable of a vehicle system; 3, calculating the correlation between the road excitation q and the output matrix Y; 4, judging a vehicle rollover risk area under the current driving working condition; 5, designing an anti-rollover cooperative coupling control strategy for vehicle chassis integrated control; on the basis of the vehicle chassis subsystem integration technology, the vehicle rollover risk can be evaluated and predicted according to the vehicle dynamic state parameters, and the vehicle rollover is actively controlled by adopting the system integration control technology.

Description

technical field [0001] The invention belongs to vehicle active control technology, in particular to an anti-rollover active control method based on vehicle chassis integrated control technology. Background technique [0002] With the continuous development of information technology, its advanced concepts and technologies have gradually affected the traditional vehicle field, so that intelligent driving, system safety prediction and semi-active / active control have become the focus of research. The vehicle system is no longer a simple mechanical assembly of different subsystems, but has gradually become a comprehensive intelligent platform obtained by integrating different hardware mechanisms and advanced driver assistance systems. So on this basis, modern vehicle chassis control technology incorporates more factors that consider ergonomics and performance intelligence, so that each subsystem of the vehicle and between vehicles become a control cluster. [0003] As one of the...
