Abstract

An accelerator pedal erroneous operation responding apparatus for a vehicle is provided. The apparatus includes an erroneous operation determining unit which determines whether or not an accelerator pedal of the vehicle is erroneously operated when the accelerator pedal is operated, a deviation determining unit which determines whether or not the vehicle would deviate from a safe area when brake torque is generated for a left braking wheel and a right braking wheel of the vehicle at a current tire rudder angle of a wheel for steering of the vehicle, if the erroneous operation determining unit determines that the accelerator pedal is erroneously operated, and a brake torque generation controlling unit which generates brake torque for the right braking wheel or the left braking wheel, if the deviation determining unit determines that the vehicle would deviate from the safe area.

Claims

1. An accelerator pedal erroneous operation responding apparatus for a vehicle, comprising:

an erroneous operation determining unit which determines whether or not an accelerator pedal of the vehicle is erroneously operated when the accelerator pedal is operated;

a deviation determining unit which determines whether or not the vehicle would deviate from a safe area when brake torque is generated for a left braking wheel and a right braking wheel of the vehicle at a current tire rudder angle of a wheel for steering of the vehicle, if the erroneous operation determining unit determines that the accelerator pedal is erroneously operated; and

a brake torque generation controlling unit which generates brake torque for the right braking wheel or the left braking wheel, if the deviation determining unit determines that the vehicle would deviate from the safe area.

2. The accelerator pedal erroneous operation responding apparatus according to claim 1, further comprising:

a request yaw rate calculating unit which calculates a request yaw rate depending a shape of a road existing in the direction of travel of the vehicle; and

a request yaw rate realization determining unit which determines whether or not the request yaw rate is realized without changing the tire rudder angle of the wheel for steering, wherein

if the deviation determining unit determines that the vehicle would deviate from the safe area and the request yaw rate realization determining unit determines that the request yaw rate is not realized without changing the tire rudder angle of the wheel for steering, the brake torque generation controlling unit generates brake torque for the right braking wheel or the left braking wheel and changes the tire rudder angle of the wheel for steering, to meet the request yaw rate.

3. The accelerator pedal erroneous operation responding apparatus according to claim 2, wherein

when the brake torque generation controlling unit generates brake torque for the right braking wheel or the left braking wheel and changes the tire rudder angle of the wheel for steering, a steering wheel of the vehicle is not synchronized with the change of the tire rudder angle.

4. The accelerator pedal erroneous operation responding apparatus according to claim 1, further comprising an alarm unit which issues an alarm to the periphery of the vehicle when the erroneous operation determining unit determines that the accelerator pedal is erroneously operated.

5. An accelerator pedal erroneous operation responding apparatus for a vehicle, comprising:

an erroneous operation determining unit which determines whether or not an accelerator pedal of the vehicle is erroneously operated when the accelerator pedal is operated;

a deviation determining unit which determines whether or not the vehicle would deviate from a safe area when brake torque is generated for a left braking wheel and a right braking wheel of the vehicle by a first distribution ratio at a current tire rudder angle of a wheel for steering of the vehicle, if the erroneous operation determining unit determines that the accelerator pedal is erroneously operated; and

a brake torque generation controlling unit which generates brake torque for the right braking wheel and the left braking wheel by the first distribution ratio, if the deviation determining unit determines that the vehicle would not deviate from the safe area, and generates brake torque for at least one of the right braking wheel and the left braking wheel by a second distribution ratio, if the deviation determining unit determines that the vehicle would deviate from the safe area.

6. A storage medium which stores a computer readable program used for an accelerator pedal erroneous operation responding apparatus for a vehicle, the program comprising:

determining whether or not an accelerator pedal of the vehicle is erroneously operated when the accelerator pedal is operated;

determining whether or not the vehicle would deviate from a safe area when brake torque is generated for a left braking wheel and a right braking wheel of the vehicle at a current tire rudder angle of a wheel for steering of the vehicle, if it is determined that the accelerator pedal is erroneously operated; and

generating brake torque for the right braking wheel or the left braking wheel, if it is determined that the vehicle would deviate from the safe area.

7. A storage medium which stores a computer readable program used for an accelerator pedal erroneous operation responding apparatus for a vehicle, the program comprising:

determining whether or not an accelerator pedal of the vehicle is erroneously operated when the accelerator pedal is operated;

determining whether or not the vehicle would deviate from a safe area when brake torque is generated for a left braking wheel and a right braking wheel of the vehicle by a first distribution ratio at a current tire rudder angle of a wheel for steering of the vehicle, if it is determined that the accelerator pedal is erroneously operated; and

generating brake torque for the right braking wheel and the left braking wheel by the first distribution ratio, if it is determined that the vehicle would not deviate from the safe area, and generating brake torque for at least one of the right braking wheel and the left so braking wheel by a second distribution ratio, if it is determined that the vehicle would deviate from the safe area.
