1. A vehicle traveling control apparatus applied to a vehicle, said vehicle including:
- an engine that supplies, to drive wheels of said vehicle, a driving force for traveling said vehicle;
a brake actuator that applies a braking force to said vehicle; and
an acceleration pedal operation amount detecting sensor that detects an acceleration pedal operation amount of said vehicle,said vehicle traveling control apparatus comprising an electric control unit which is configured;
to continuously determine whether or not a driver of said vehicle is under an abnormal state that said driver loses an ability of driving said vehicle; and
to execute a vehicle stop control for having said brake actuator apply said braking force to said vehicle to stop said vehicle after said electric control unit determines that said driver is under said abnormal state,wherein,said electric control unit is configured;
to acquire a driver requiring driving force which is a driving force required by said driver and is decided on the basis of said acceleration pedal operation amount;
to execute a stopped state maintaining control for maintaining said vehicle at a stopped state by performing a driving force limiting control for limiting a supply requiring driving force which said engine is requested to supply to said drive wheels on the basis of said driver requiring driving force to a value equal to or smaller than a driving force which is smaller than said driver requiring driving force, and by performing a continuous braking to continuously apply said braking force to said vehicle from said brake actuator, while said vehicle is stopped through said vehicle stop control; and
to forbid a termination of said stopped state maintaining control when (i) said acceleration pedal operation amount is equal to or greater than a threshold value larger than zero and (ii) said termination of said stopped state maintaining control is requested during executing said stopped state maintaining control.

Abstract
A vehicle traveling control apparatus stops a vehicle when the driver is under the abnormal state that the driver loses an ability of driving the vehicle, and then performs a stopped state maintaining control to maintain the vehicle at the stopped state. The control apparatus forbids a termination of the stopped state maintaining control if the acceleration pedal operation amount is equal to or greater than a threshold value greater than zero when the termination of the stopped state maintaining control is requested.
