Title: Lane deviation warning device for vehicle
Inventor: TANIDA KOJI
IPC: G08G1/16
Filed: 2000-07-26
Abstract: PROBLEM TO BE SOLVED: To accurately alarming to a driver by accurately judging the presence or absence of possibility of line deviation of a driver's own car. SOLUTION: Since when a operation other than driving detection means M4 detects operations of the driver other than driving operation such as wheel operation, accelerator operation or braking operation, a line deviation criterion change means M5 changes a line deviation criterion, when a line deviation judgment means M2 judges line deviation of the driver's own car based on the result of comparison of positional relationship of the car to a line which is detected by a traveling position detection means M1 with a predetermined line deviation criterion, if a consciousness level of the driver is apart from driving operation and line deviation becomes easy to be generated, the line deviation can be judged earlier based on the changed line deviation criterion.  Furthermore, when the consciousness level of the driver is concentrated on driving operation, the presence of possibility of line deviation is not judged even if a vehicle is unsteadiness to some degree, thereby, an undesirable alarm for the driver is not issued.
