Abstract

A traveling control device comprises an obstacle detecting portion to detect an obstacle in front of a vehicle, a dangerous-area setting portion to set a contact-dangerous area with a specified width which is located beside the obstacle which is detected by the obstacle detecting portion, an entry detecting portion to detect an entry of the vehicle into the contact-dangerous area, and a warning control portion to operate a warning device when the entry of the vehicle into the contact-dangerous area is detected by the entry detecting portion. Accordingly, it can be surely prevented that the vehicle approaches the obstacle too close or contacts the obstacle, thereby improving the safety of the vehicle traveling.

Claims

1. A traveling control device of a vehicle, comprising:

an obstacle detecting means operative to detect an obstacle in front of the vehicle;

a dangerous-area setting means operative to set a contact-dangerous area with a specified width which is located beside the obstacle which is detected by said obstacle detecting means;

an entry detecting means operative to detect an entry of the vehicle into the contact-dangerous area set by said dangerous-area setting means; and

a warning control means operative to operate a warning means when the entry of the vehicle into the contact-dangerous area is detected by said entry detecting means.

2. The traveling control device of a vehicle of claim 1, further comprising an obstacle determining means operative to determine whether the obstacle detected by said obstacle detecting means is a two-wheeled vehicle or not, wherein said dangerous-area setting means is configured to set the contact-dangerous area only when it is detected by the obstacle determining means that the obstacle is the two-wheeled vehicle.

3. The traveling control device of a vehicle of claim 1, further comprising a passing-possibility determining means operative to determine whether the vehicle can pass the obstacle without entering into the contact-dangerous area set by said dangerous-area setting means, wherein said warning control means is configured to further operate the warning means when it is determined by the passing-possibility determining means that the vehicle cannot pass the obstacle without entering into the contact-dangerous area.

4. The traveling control device of a vehicle of claim 3, further comprising a braking control means operative to operate a braking means of the vehicle when it is determined by the passing-possibility determining means that the vehicle cannot pass the obstacle without entering into the contact-dangerous area.

5. The traveling control device of a vehicle of claim 1, further comprising a braking control means operative to operate a braking means of the vehicle when it is determined by said entry detecting means that the entry of the vehicle into the contact-dangerous area is detected.

6. The traveling control device of a vehicle of claim 1, further comprising an assist means operative to assist the vehicle so that the vehicle travels inside a specified traveling lane and an inside-traveling-lane passing-possibility determining means operative to determine whether the vehicle can pass the obstacle inside the specified traveling lane without entering into the contact-dangerous area set by said dangerous-area setting means, wherein said assist means is configured not to operate when it is determined by the inside-traveling-lane passing-possibility determining means that the vehicle cannot pass the obstacle without entering into the contact-dangerous area.

7. The traveling control device of a vehicle of claim 6, further comprising a passing determining means operative to determine whether the vehicle has passed the obstacle or not, wherein said assist means is configured to restart an operation thereof when it is determined by said passing determining means that the vehicle has passed the obstacle.
