Abstract
A vehicle control apparatus and a method thereof include a first controller configured to perform control for safety of a vehicle; a second controller configured to mainly perform determination and control of autonomous driving of the vehicle; and a third controller configured to subordinately perform the determination and the control of the autonomous driving of the vehicle, wherein the third controller is configured to determine whether the second controller fails, when the second controller fails, to change a control subject for performing an autonomous driving function from the second controller to the third controller, and to transmit control subject change information to the first controller.
Claims18
A vehicle control apparatus comprising:
- a first controller configured to perform control for safety of a vehicle;
- a second controller configured to mainly perform determination and control of autonomous driving of the vehicle;
- and
- a third controller configured to subordinately perform the determination and the control of the autonomous driving of the vehicle,
- wherein the third controller is configured to determine whether the second controller fails, when the second controller fails, to change a control subject for performing an autonomous driving function from the second controller to the third controller, and to transmit control subject change information to the first controller,
- wherein the third controller is further configured to have a risk level which is higher than or equal to a risk level of the second controller,
- wherein, when the second controller fails, the first controller is configured to:
- receive a vehicle control command for fault response from the third controller based on the control subject being changed from the second controller to the third controller, and
- perform a failure response strategy response based on the control subject is changed from the second controller to the first controller by itself.
A control method for a vehicle control apparatus including a first controller that performs control for safety of a vehicle, a second controller that mainly performs determination and control of autonomous driving of the vehicle, and a third controller that subordinately performs the determination and the control of the autonomous driving of the vehicle, the method comprising:
- determining, by the third controller, whether the second controller fails;
- changing a control subject for a failure response strategy from the second controller to the third controller when the second controller fails;
- transmitting control subject change information related to the control subject being changed from the second controller to the third controller, to the first controller;
- receiving, by the first controller, a vehicle control command for fault response from the third controller based on the control subject being changed from the second controller to the third controller when the second controller fails;
- and
- performing, by the first controller, a failure response strategy response based on the control subject being changed from the second controller to the first controller by itself when the second controller fails,
- wherein the third controller is configured to have a risk level which is higher than or equal to a risk level of the second controller.
