Apparatus and method for controlling vehicle

A method for controlling a vehicle by monitoring a driver's state, the method comprising:

• setting a first steering control region, a first steering warning region, a braking control region, and a first braking warning region of the vehicle;
• determining the driver's state by monitoring a state of a driver;
• and
• if the determined driver's state is in an abnormal state, resetting the first steering control region, the first steering warning region, and the first braking warning region of the vehicle, to set a second steering control region, a second steering warning region, and a second braking warning region,
• wherein
• the braking control region, the first braking warning region, and the second braking warning region are formed on the basis of a distance to a front vehicle,
• a distance of the first braking warning region is shorter than a distance of the second braking warning region, and
• a distance of the braking control region is shorter than a distance of the first braking warning region, and
• wherein
• the first braking warning region includes a first warning region, a second warning region, and a third warning region, and
• the second braking warning region includes a first early warning region and a second early warning region, and
• wherein
• a warning start time of the first early warning region is earlier than a warning start time of the first warning region and
• a warning start time of the second early warning region is earlier than a warning start time of the second warning region.

An apparatus for controlling a vehicle by monitoring a driver's state, comprising:

• a sensor unit configured to detect at least two of a steering angle, a steering-angle speed, lateral acceleration, and vehicle speed;
• a front camera configured to capture a front-view image of the vehicle;
• a driver camera configured to capture an image of a driver;
• a driver state decision unit configured to determine, based on the image captured by the driver camera, whether the driver is in an abnormal state;
• a controller configured to control steering and braking of the vehicle according to a determined result of the driver state decision unit;
• and
• a warning unit configured to warn the driver of a dangerous state according to a control signal of the controller,
• wherein
• a steering control region for determining steering control of the vehicle, a steering warning region for determining steering warning of the vehicle, a braking control region for determining braking control of the vehicle, and a braking warning region for determining braking warning of the vehicle are established in the controller, and
• the controller performs resetting of the steering control region, the steering warning region, and the braking warning region according to the determined result of the driver state decision unit,
• wherein
• the controller, if the driver is in an abnormal state according to the determined result of the driver state decision unit, performs resetting of respective regions in a manner that the steering control region, the steering warning region, and the braking warning region are extended in size, and
• wherein
• the braking warning region includes a first warning region, a second warning region, and a third warning region according to a distance to a front vehicle;
• and
• the controller, if the driver is in the abnormal state according to the determined result of the driver state decision unit, performs resetting in a manner that the first warning region and the second warning region are extended in size.
