Vehicular suspension rigidity controlling apparatus and method with roll-over preventive feature

摘要

In vehicular suspension rigidity controlling apparatus and method, a plurality of suspensions intervened between a sprung mass of a vehicle body and an unsprung mass of a corresponding road wheel, a suspension rigidity adjusting section is installed to be enabled to adjust a rigidity of each suspension, a driving state of the vehicle is detected, a predictive determination is made whether the vehicular driving state is a state in which there is a possibility that the vehicle is rolled over from the detected driving state of the vehicle, and the rigidity of at least one of the suspensions is controllably adjusted in a direction to decrease a potential energy of the sprung mass of the vehicle when predictively determining that the vehicular driving state is the state that there is the possibility that the vehicle is rolled over.
