1. An automotive lane deviation prevention apparatus comprising:

  • braking force actuators that adjust braking forces applied to respective road wheels;

    sensors that detect a driving state of a host vehicle and a traveling-path condition where the host vehicle is traveling; and

    a control unit being configured to be electronically connected to the braking force actuators and the sensors, for controlling the braking force actuators in response to signals from the sensors for lane deviation avoidance purposes;

    the control unit comprising (a) a lane-deviation-avoidance (LDA) controlled variable setting section that sets a yaw-moment-control LDA controlled variable used to avoid the host vehicle'"'"'s lane deviation by way of yaw moment control and a deceleration-control LDA controlled variable used to avoid the host vehicle'"'"'s lane deviation by way of vehicle deceleration control, based on at least one of the host vehicle'"'"'s driving state and the traveling-path condition, when the host vehicle has a tendency to deviate from a driving lane; and

    (b) a control section that controls the braking force of each of the road wheels based on the yaw-moment-control LDA controlled variable and the deceleration-control LDA controlled variable.
