Abstract
An obstacle detecting portion (11) on a vehicle detects an obstacle behind the vehicle. A CPU (20) detects the direction of the driver's line of sight based on a driver's face image captured by a camera (12). The CPU (20) determines whether the direction of the driver's line of sight directed to mirrors (51L, 51R) reflecting an image of the obstacle behind the vehicle. According to the result of the determination, the CPU (20) sets the level of an alarm to be outputted by warning signal outputting portions (15, 16).
Claims10
A warning device for a vehicle, comprising:
- an obstacle detecting portion detecting an obstacle located at a rear side of the vehicle;
- a warning signal outputting portion outputting a warning signal when the obstacle is detected by the obstacle detecting portion;
- a mirror reflecting an image of the obstacle;
- a visual line direction recognizing portion recognizing a visual line direction of an operator of the vehicle;
- a determining portion determining whether or not the visual line of the operator is directed towards the mirror on the basis of the visual line direction of the operator recognized by the visual line direction recognizing portion;
- and
- a warning level setting portion setting a warning level of the warning signal to be outputted by the warning signal outputting portion in accordance with a determined result of the determining portion.
A warning device for a vehicle, comprising:
- an obstacle detecting portion detecting an obstacle located at a rear side of the vehicle and measuring a distance between the vehicle and the detected object;
- a warning signal outputting portion outputting a warning signal when the obstacle is detected by the obstacle detecting portion;
- and
- a warning level setting portion setting a warning level of a warning signal to be outputted by the warning signal outputting portion on the basis of the distance measured by the obstacle detecting portion.
A warning method for a vehicle, comprising:
- an obstacle detecting step for detecting an obstacle located at a rear side of the vehicle;
- a warning signal outputting step for outputting a warning signal when the obstacle is detected;
- a visual line direction recognizing step for recognizing a visual line direction of an operator of the vehicle;
- a determining step for determining whether or not the visual line of the operator is directed towards a mirror reflecting an image of the obstacle;
- and
- a warning level setting step for setting a warning level of the warning signal to be outputted in accordance with a result determined in the determining step.
