Patent ID: 8311729

Claim:
A traffic lane deviation preventing system for a vehicle, comprising: a traffic line detector for detecting the position of a traffic line on a road; a controller for determining a possibility of vehicle deviation from the traffic line, based on the position of the traffic line detected by said traffic line detector, said controller is configured to carry out deviation preventing control by setting a travel target point and transmitting a signal to a responsive unit so that the vehicle travels toward the travel target point when it is determined that vehicle deviation from the traffic line is possible; and a counter for counting the passage of a control operation time of said deviation preventing control, wherein said controller is further configured to set a current travel target point at a point moved from a previous travel target point set in a previous sampling cycle by a prescribed distance toward the center of a traffic lane in which the vehicle travels, with each sampling cycle, until said control operation time counted by said counter becomes a prescribed time.
