Traffic lane deviation preventing system for a vehicle
First Claim

1. 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, whereinsaid 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.

Abstract
A traffic lane deviation preventing system includes a traffic line detecting unit for detecting traffic line positions on a road, a control unit for determining a possibility of a vehicle'"'"'s deviation from a traffic line based on the traffic line positions detected by the traffic line detecting unit and setting a travel target point to which the vehicle is to travel if it is determined that there is a possibility of a traffic line deviation. The control unit moves the travel target point toward the center of a traffic lane according to the passage of a control operation time.

21. 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 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 sampling cycles based on a control operation time of said deviation preventing control, during which control operation time the vehicle travels toward the travel target point, wherein said controller is further configured to control said travel target point to move from a previous travel target point in a direction toward the center of a traffic lane in which the vehicle travels, with each sampling cycle, until said control operation time becomes a prescribed time. - View Dependent Claims (22, 23)
