  • Patent number: 8135528
    Abstract: An actual vehicle actuator operation control input and a model operation control input are determined by an FB distribution law such that the difference between a reference state amount determined in a vehicle model and an actual state amount of an actual vehicle approximates zero, and then an actuator device of the actual vehicle and the vehicle model are operated on the basis of the control inputs. The value of a parameter of the vehicle model set according to an actual vehicle motional state such that the attenuation property of a reference state amount when a drive manipulated variable is changed is higher than the attenuation property of an actual state amount. Accordingly, the actual vehicle actuator device is properly controlled independently of an actual vehicle motional state such that a state amount related to an actual vehicle motion approximates a vehicle state amount on a dynamic characteristic model.

  • Patent number: 8086383
    Abstract: A control input for operating an actual vehicle actuator and a control input for operating a vehicle model are determined by an FB distribution law based on a difference between a reference state amount determined by a vehicle model and an actual state amount of an actual vehicle such that the state amount error is approximated to zero, and then an actuator device of the actual vehicle and the model vehicle are operated based on the control inputs. The FB distribution law determines a control input for operating the model such that a state amount error is approximated to zero while restraining a predetermined restriction object amount from deviating from a permissible range. A vehicle control device capable of enhancing robustness against disturbance factors or their changes while performing operation control of actuators that is as suited to behaviors of an actual vehicle as possible is provided.

  • Patent number: 8027775
    Abstract: A basic required manipulated variable Mfbdmd_a is determined on the basis of a state amount error, which is the difference between a state amount of a motion of an actual vehicle 1 and a reference state amount, then a driving/braking force manipulation control input Fxfbdmd_n of a wheel is determined on the basis of the above basic required manipulated variable. At this time, a change in a driving/braking force operation control input Fxdmd_n of a front wheel and a rear wheel, respectively, of a particular set is made to be proportional to a change in the basic required manipulated variable Mfbdmd_a, and the ratio (gain) of a change in Fxdmd_n with respect to a change in Mfbdmd_a is made to change on the basis of gain adjustment parameters, such as side slip angles ?f_act and ?r_act.

  • Patent number: 8024091
    Abstract: An FB distribution rule 20 determines an actual vehicle actuator operation control input and a vehicle model operation control input such that a difference between a reference state amount determined by a vehicle model 16 and an actual state amount of an actual vehicle 1 (a state amount error) approximates to zero, and the control inputs are used to operate an actuator device 3 of the actual vehicle 1 and the vehicle model 16. In the FB distribution law 20, when an actual vehicle feedback required amount based on the state amount error exists in a dead zone, then an actual vehicle actuator operation control input is determined by using the required amount as a predetermined value. A vehicle model manipulated variable control input is determined such that a state amount error is brought close to zero, independently of whether an actual vehicle feedback required amount exists in a dead zone.

  • Patent number: 7987029
    Abstract: A control input for operating an actual vehicle actuator and a control input for operating a vehicle model are determined by an FB distribution law based on a state amount error which is a difference between a reference state amount determined by a vehicle model and an actual state amount of an actual vehicle such that the state amount error is approximated to zero. An actuator device of the actual vehicle and the model vehicle, respectively, are then operated based on the control inputs. The FB distribution law estimates an external force acting on the actual vehicle due to a control input for operating an actual vehicle actuator, and determines a control input for operating the vehicle model on the basis of the estimated value and a basic value of a control input for operating the vehicle model for approximating the state amount error to zero.
