Image forming system
First Claim
1. An image forming system for a host vehicle to alert another vehicle, traveling in an opposite lane in a direction opposite a direction of travel of the host vehicle, to a turn of the host vehicle at an intersection and across the opposite lane, the system comprising:
- an image forming unit that forms a mark with a predetermined shape on a road surface ahead of the host vehicle in the direction of travel of the host vehicle;
a pedal operation sensor that detects position, relative to a pedal, of a foot of a driver of the host vehicle;
a turn waiting detection unit that detects whether or not the host vehicle, stopped at the intersection, is in a turn waiting state;
a turn start detection unit that detects, if the turn waiting detection unit has detected that the host vehicle is in the turn waiting state, whether or not the host vehicle has been changed from the turn waiting state to a turn start state based on a change in detected positions of the driver'"'"'s foot; and
a first image forming control unit that controls the image forming unit to form a turn start mark with the predetermined shape, indicating that the host vehicle is in the turn start state, on the road surface of the opposite lane and within the intersection to be entered by the host vehicle, if the turn start detection unit detects a change from the turn waiting state to the turn start state.

Abstract
When it is determined that the host vehicle is stopped at the intersection in the right turn waiting state, the navigation ECU forms a right turn waiting mark representing the right turn waiting state on the road surface of the opposing lane at the intersection where the host vehicle is stopped with a visually identifiable laser beam with a predetermined color. When it is determined that the host vehicle is brought into the right turn start state from the right turn waiting state where the host vehicle is stopped at the intersection, the navigation ECU forms the right turn start mark representing the right turn start state instead of the right turn waiting mark on the road surface of the opposing lane at the intersection where the host vehicle enters with the visually identifiable laser beam with the color (for example, red) different from that of the right turn waiting mark, at substantially the same position thereof in accordance with the traveling state of the host vehicle.
