Title: DRIVING SUPPORT SYSTEM
Abstract: [0001]    A driving support system (11) takes an image of a lane marking on a traveling road, creates a first reference line at an inner side of the lane marking obtained based on the taken image, and alerts a driver when a vehicle passes across the first reference line. Furthermore, the driving support system changes the first reference line to a second reference line located inward of the first reference line when passing is prohibited on the traveling road where the vehicle travels, a steering angle of a steering wheel is equal to or larger than a prescribed angle toward the lane marking side, and a step-on amount of an accelerator pedal is equal to or larger than a prescribed amount (ST106).

Claims: number: 1
text: A driving support system (11) configured to support driving of a vehicle (1) by a driver, the driving support system comprising:
number: 2
text: The driving support system according to Claim 1, characterized in that the reference line changing means changes the second reference line to the first reference line when at least one of following conditions is satisfied: passing is no longer prohibited on the traveling road, the steering angle is smaller than the prescribed angle toward the lane marking, and the step-on amount is smaller than the prescribed amount.
number: 3
text: The driving support system according to Claim 1 or 2, wherein the vehicle includes a direction indicator (17) configured to alert the driver of a lane change, and
the driving support system characterized by further comprises:
number: 4
text: The driving support system according to Claim 1, comprising resistance value acquiring means (ST401) for acquiring a resistance value of a road surface of the traveling road, characterized in that 
the reference line changing means changes the second reference line to a third reference line (L3) located inward of the second reference line when the reference value acquired by the resistance value acquiring means is equal to or smaller than a prescribed value.
number: 5
text: The driving support system according to Claim 1, characterized by further comprising lane width acquiring means (ST501) for acquiring a lane width of the traveling road, characterized in that 
the reference line changing means changes the second reference line to a fourth reference line (L4) located outward of the second reference line when the lane width acquired by the lane width acquiring means is equal to or smaller than a prescribed value.
