Abstract:
1. A lane departure prevention control apparatus for an automotive vehicle, comprising: a vehicular traveling information detecting section that detects an acute angle (φ) formed between a traffic lane on which the vehicle is traveling and a forward-and backward axis of the vehicle; a deviation tendency detecting section that detects a state of a tendency of vehicular deviation from the traffic lane on which the vehicle is traveling; a deceleration controlled variable calculating section that calculates a deceleration controlled variable on the basis of the state of the tendency of the vehicular deviation from the traffic lane on which the vehicle is traveling; a braking force controlling section that controls a braking force acted upon wheels of the vehicle on the basis of the calculated deceleration controlled variable; and a correcting section that corrects at least one of a parameter for detecting the state of the tendency of the deviation from the traffic lane on which the vehicle is traveling so as to detect lane deviation at an earlier timing, and a parameter for computing the calculated deceleration controlled variable so as to increase the calculated deceleration controlled variable, as the acute angle (φ) becomes larger.
