Abstract
Official abstract text for this publication.
The present invention provides a vehicle control apparatus that controls automated driving of a vehicle, comprising: a first travel controller configured to control travel of the vehicle; a second travel controller configured to control travel of the vehicle based on an instruction from the first travel controller; a first controller configured to control a first actuator based on an instruction from the first travel controller; and a second controller configured to control a second actuator based on an instruction from the second travel controller, wherein in a case in which degradation of a communication function between the first travel controller and the second travel controller is detected in a state where the actuator group is performed by the second controller, alternative control of the vehicle is performed by the second travel controller.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle control apparatus that controls automated driving of a vehicle, comprising: a first travel controller configured to control travel of the vehicle; a second travel controller configured to control travel of the vehicle based on an instruction from the first travel controller; a first controller configured to control a first actuator based on an instruction from the first travel controller; and a second controller configured to control a second actuator based on an instruction from the second travel controller, wherein a control performer of an actuator group including the first actuator and the second actuator is switched between the first controller and the second controller in accordance with a state of the first travel controller, and in a case in which degradation of a communication function between the first travel controller and the second travel controller is detected in a state where the actuator group is performed by the second controller, alternative control of the vehicle is performed by the second travel controller. 2 . The vehicle control apparatus according to claim 1 , wherein the alternative control is degeneracy control of the automated driving of the vehicle. 3 . The vehicle control apparatus according to claim 1 , wherein in a case in which the degradation of the communication function between the first travel controller and the second travel controller is detected in a state where the actuator group is performed by the first controller, degeneracy control of the automated driving of the vehicle is performed by the first travel controller. 4 . The vehicle control apparatus according to claim 1 , wherein the first travel controller and the second travel controller are connected by a first communication line and a second communication line which is different from the first communication line, and in a case in which degradation of communication functions in the first communication line and the second communication line is detected in a state where the actuator group is performed by the second controller, the alternative control of the vehicle is performed by the second travel controller. 5 . The vehicle control apparatus according to claim 1 , wherein the actuator group includes an actuator of a device related to one of steering and braking. 6 . A vehicle control method for controlling automated driving of a vehicle that comprises a first travel controller configured to control travel of the vehicle, a second travel controller configured to control travel of the vehicle based on an instruction from the first travel controller, a first controller configured to control a first actuator based on an instruction from the first travel controller, and a second controller configured to control a second actuator based on an instruction from the second travel controller, wherein a control performer of an actuator group including the first actuator and the second actuator is switched between the first controller and the second controller in accordance with a state of the first travel controller, and in a case in which degradation of a communication function between the first travel controller and the second travel controller is detected in a state where the actuator group is performed by the second controller, alternative control of the vehicle is performed by the second travel controller.
