Patent ID: 8565935

Claim:
A lateral motion control apparatus comprising: a target value obtaining unit that obtains a target value of a lateral motion amount of a vehicle; a control amount calculation unit that calculates, based on the target value of the lateral motion amount obtained by the target value obtaining unit, lateral motion control amounts for each of a plurality of control targets that operate cooperatively in order to change the lateral motion amount of the vehicle; a control target control unit that controls the plurality of control targets based on the lateral motion control amounts; a control stop determination unit that determines whether or not to stop the control of the plurality of control targets performed by the control target control unit; and a degeneration control amount determination unit that, when the control stop determination unit has determined that the control of the plurality of control targets is to be stopped, determines lateral motion degeneration control amounts for each of the plurality of control targets so that the lateral motion control amounts of the plurality of control targets degenerate, wherein, when the control stop determination unit has determined that the control of the plurality of control targets is to be stopped, the control target control unit controls the plurality of control targets based on the lateral motion degeneration control amounts determined by the degeneration control amount determination unit.
