Abstract
In an automotive lane deviation prevention (LDP) apparatus capable of executing LDP control by which a host vehicle is avoided from deviating from a driving lane, a control unit includes an LDP control allotted amount calculation section that calculates, responsively to a host vehicle's turning state, a steering-control allotted amount for LDP control and a braking-force-control allotted amount for LDP control, in presence of the host vehicle's lane-deviation tendency from the driving lane. In order to avoid the host vehicle's lane-deviation tendency, steering torque is controlled responsively to a steering-torque-control controlled variable determined based on the steering-control allotted amount, whereas braking forces applied to respective road wheels are controlled responsively to braking-force-control controlled variables determined based on the braking-force-control allotted amount.
