SUSPENSION DEVICE AND AUTOMOTIVE VEHICLE FITTED WITH SUCH DEVICE

摘要

The invention relates to a suspension device for an automotive vehicle, wherein said device includes suspension actuators acting individually on the wheels of said vehicle, said vehicle having given physical parameters and being provided with sensors for estimating rolling variables (?<SUB>x</SUB>, ?<SUB>y</SUB>, ?, h<SUB>1</SUB>, h<SUB>2</SUB>, h<SUB>0</SUB>, l<SUB>1</SUB>, l<SUB>2</SUB>) and driving requests (a, P<SUB>F</SUB>, P<SUB>A</SUB>), the device being characterised in that it comprises sensors for measuring the ground vertical force (F<SUB>z11</SUB>, F<SUB>z12</SUB>, F<SUB>z21</SUB>, F<SUB>z22</SUB>) applied on each of said wheels, and control means for calculating, according to said parameters, variables and/or requests, and outputting instructions towards at least one of said actuators in order to increase the ground vertical force (F<SUB>z11</SUB>, F<SUB>z12</SUB>, F<SUB>z21</SUB>, F<SUB>z22</SUB>) applied on one of said wheels.
