Abstract
A device and a method for controlling autonomous driving are provided The device includes non-transitory memory storing instructions executable to control an autonomous driving; and a processor configured to execute the instructions to determine whether a collision has occurred using an acceleration sensor mounted on an airbag control unit during the autonomous driving, determine a collision direction based on a change in acceleration of three axes obtained by the acceleration sensor, and perform an emergency action by controlling at least one of longitudinal direction travel or transverse direction travel based on the collision direction.
Claims12
A device comprising:
- non-transitory memory storing instructions executable to control an autonomous driving of a vehicle;
- and
- a processor configured to execute the instructions to:
- determine whether a collision has occurred to the vehicle using an acceleration sensor mounted on an airbag control unit during the autonomous driving;
- determine a collision direction based on a change in acceleration of three axes obtained by the acceleration sensor;
- and
- perform an emergency action by controlling at least one of longitudinal direction travel or latitudinal direction travel based on the collision direction, wherein the processor is further configured to:
- when the collision direction is a forward direction, immediately transmit a braking command to a brake controller to stop the vehicle,
- when the collision direction is a rearward direction, move the vehicle until an acceleration of an x-axis becomes equal to or less than a predetermined reference acceleration, and transmit the braking command to the brake controller to stop the vehicle,
- when the collision direction is a left direction, transmit a steering control command to a steering controller to stop the vehicle on a right side of a travel lane, and
- when the collision direction is a right direction, transmit the steering control command to the steering controller to stop the vehicle on a left side of the travel lane.
A method for controlling autonomous driving, the method comprising:
- determining whether a collision has occurred to a vehicle using an acceleration sensor mounted on an airbag control unit during the autonomous driving of the vehicle;
- determining a collision direction based on a change in acceleration of three axes obtained by the acceleration sensor;
- and
- performing an emergency action by controlling at least one of longitudinal direction travel or latitudinal direction travel based on the collision direction,
- wherein the performing of the emergency action includes:
- when the collision direction is a forward direction, immediately transmitting a braking command to a brake controller to stop the vehicle,
- when the collision direction is a rearward direction, moving the vehicle until an acceleration of an x-axis becomes equal to or less than a predetermined reference acceleration, and transmitting the braking command to the brake controller to stop the vehicle,
- when the collision direction is a left direction, transmitting a steering control command to a steering controller with to stop the vehicle on a right side of a travel lane, and
- when the collision direction is a right direction, transmitting the steering control command to the steering controller to stop the vehicle on a left side of the travel lane.
