Abstract

A vehicle traveling controller performs emergency evacuation traveling in the case of an emergency. The vehicle traveling controller determines whether a vehicle traveling in accordance with a normal traveling rule is not dangerous and becomes proper traveling or not based on environmental information around the vehicle, when it is determined that the vehicle traveling in accordance with the normal traveling rule becomes proper traveling, executes normal traveling control for instructing the vehicle to travel in accordance with the normal traveling rule, and when the vehicle traveling in accordance with the normal traveling rule does not become proper traveling, executes emergency evacuation traveling control for instructing the vehicle to perform emergency evacuation traveling not in accordance with the normal traveling rule. Therefore, emergency evacuation traveling with high safety can be performed, compared with vehicle traveling in accordance with the normal traveling rule, so safety of vehicle traveling can be improved.

Claims

1. (canceled)

2. A vehicle traveling controller comprising:

a normal traveling control unit which instructs a vehicle to travel in accordance with traffic regulations;

a traveling propriety determination unit which determines whether the vehicle traveling in accordance with the traffic regulations becomes proper traveling or not on the basis of environmental information around the vehicle; and

an emergency evacuation traveling control unit which instructs the vehicle to perform emergency evacuation traveling, which is not in accordance with the traffic regulations, when the traveling propriety determination unit determines that the vehicle traveling in accordance with the traffic regulations does not become proper traveling.

3. The vehicle traveling controller according to claim 2,

wherein the traveling propriety determination unit determines whether the vehicle traveling in accordance with the traffic regulations exceeds the degree of danger set in advance or not on the basis of the environmental information, and

when the traveling propriety determination unit determines that the vehicle traveling in accordance with the traffic regulations exceeds the degree of danger set in advance, the emergency evacuation traveling control unit instructs the vehicle to perform emergency evacuation traveling which is not in accordance with the traffic regulations.

4. The vehicle traveling controller according to claim 2,

wherein the normal traveling control unit instructs the vehicle to travel in accordance with a plurality of traffic regulations,

the traveling propriety determination unit determines whether the vehicle traveling in accordance with all of the plurality of traffic regulations becomes proper traveling or not on the basis of the environmental information around the vehicle, and

when the traveling propriety determination unit determines that the vehicle traveling in accordance with all of the plurality of traffic regulations does not become proper traveling, the emergency evacuation traveling control unit instructs the vehicle to perform emergency evacuation traveling, which is not in accordance with the traffic regulations, on the basis of priority set for the plurality of traffic regulations.
