A method to be executed by a computer mounted on a vehicle, the vehicle including a plurality of drive assist devices configured to implement a plurality of drive assist functions, respectively, and an update information generation device configured to generate update information to be used by at least one of the drive assist devices to update a middle point in steering control performed by the at least one of the drive assist devices, the method comprising:
determining whether update of the middle point by the at least one of the drive assist devices is allowed; and
issuing a notification that permits a process of updating the middle point using the update information, to the plurality of the drive assist devices upon determining that the update of the middle point is allowed, wherein:
it is determined that the update of the middle point is allowed while respective operations of all of the drive assist devices are stopped;
a certain drive assist device among the plurality of the drive assist devices includes the update information generation device, and when the certain drive assist device receives the notification that permits the process of updating the middle point, the update information generation device in the certain drive assist device generates the update information; and
other drive assist devices than the certain drive assist device among the plurality of the drive assist devices do not generate the update information and instead receive the update information from the certain drive assist device, the update information being generated by the update information generation device included in the certain drive assist device.
6. A non-transitory storage medium storing instructions, which when executed by a computer mounted on a vehicle, causes the computer to perform a process, the vehicle including a plurality of drive assist devices configured to implement a plurality of drive assist functions, respectively, and an update information generation device configured to generate update information to be used by at least one of the drive assist devices to update a middle point in steering control performed by the at least one of the drive assist devices,
the process comprising:
determining whether update of the middle point by the at least one of the drive assist devices is allowed; and
issuing a notification that permits a process of updating the middle point using the update information, to the plurality of the drive assist devices upon determining that the update of the middle point is allowed, wherein:
it is determined that the update of the middle point is allowed while respective operations of all of the drive assist devices are stopped;
a certain drive assist device among the plurality of the drive assist devices includes the update information generation device, and when the certain drive assist device receives the notification that permits the process of updating the middle point, the update information generation device in the certain drive assist device generates the update information; and
other drive assist devices than the certain drive assist device among the plurality of the drive assist devices do not generate the update information and instead receive the update information from the certain drive assist device, the update information being generated by the update information generation device included in the certain drive assist device.
