Control device for vehicle, control method, non-transitory computer-readable storage medium, manager, and vehicle

1. A control device installed in a vehicle, the control device comprising an electronic control unit configured to:

accept a plurality of first requests from a driving assistance electronic control unit;

arbitrate the first requests;

calculate a second request that is a physical amount that differs from the first requests based on a result of arbitration in which the first requests are arbitrated; and

distribute the second request to at least one actuator system of a plurality of actuator systems, wherein

when the electronic control unit determines that the first request requesting a driving force exceeds a first driving force necessary for recovery from a fuel cut state, the electronic control unit performs arbitration such that an actual driving force generated by the vehicle is no greater than the first driving force, until reaching a driving force lower limit realizable by a powertrain actuator included in an actuator system of the plurality of actuator systems at a current gear ratio.

2. The control device according to claim 1 , wherein the electronic control unit is configured to, when there is the first request requesting a driving force exceeding the first driving force, set an arbitrated driving force that is a driving force output as arbitration results to the first driving force, until the actual driving force of the vehicle reaches the driving force lower limit of the powertrain actuator.

3. The control device according to claim 2 , wherein the electronic control unit is configured to, following maintaining the arbitrated driving force at the first driving force for a first duration of time, set the arbitrated driving force to the driving force lower limit of the powertrain actuator.

4. The control device according to claim 3 , wherein the electronic control unit is configured to, following maintaining output of the driving force lower limit for a second duration of time, increase, by a prescribed jerk, a driving force output as arbitration results to a requested driving force that is a result of arbitration of the first requests.

5. A manager installed in a vehicle, the manager comprising:

an electronic control unit that is configured to:

accept a plurality of kinematic plans from a plurality of advanced driving-assistance system applications;

arbitrate the plurality of kinematic plans;

calculate a motion request based on arbitration results; and

distribute the motion request to at least one actuator system of a plurality of actuator systems, wherein

in response to a kinematic plan of the plurality of kinematic plans requesting a driving force exceeding a first driving force necessary for recovery from a fuel cut state, the electronic control unit performs arbitration such that an actual driving force generated by the vehicle is no greater than the first driving force, until reaching a driving force lower limit realizable by a powertrain actuator included in an actuator system of the plurality of actuator systems at a current gear ratio.

6. A control method executed by a computer of a manager installed in a vehicle, the control method comprising:

accepting a plurality of kinematic plans from a plurality of ADAS applications;

arbitrating the plurality of kinematic plans;

calculating a motion request based on arbitration results from the arbitrating; and

distributing the motion request to at least one actuator system of a plurality of actuator systems, wherein

in response to a kinematic plan of the plurality of kinematic plans requesting a driving force exceeding a first driving force necessary for recovery from a fuel cut state, in the arbitrating, arbitration is performed such that an actual driving force generated by the vehicle is no greater than the first driving force, until reaching a driving force lower limit realizable by a powertrain actuator included in an actuator system of the plurality of actuator systems at a current gear ratio.

7. A non-transitory computer-readable storage medium storing a program that is executable by a computer of a manager installed in a vehicle and that causes the computer to perform functions comprising:

accepting a plurality of kinematic plans from a plurality of ADAS applications; and

arbitrating the plurality of kinematic plans;

calculating a motion request based on arbitration results from the arbitrating;

distributing the motion request to at least one actuator system of a plurality of actuator systems, wherein

in response to a kinematic plan of the plurality of kinematic plans requesting a driving force exceeding a first driving force necessary for recovery from a fuel cut state, in the arbitrating, arbitration is performed such that an actual driving force generated by the vehicle is no greater than the first driving force, until reaching a driving force lower limit realizable by a powertrain actuator included in an actuator system of the plurality of actuator systems at a current gear ratio.

8. A vehicle, wherein the control device according to claim 1 is installed.
