Abstract: A vehicle comprises a plurality of drive assist devices configured to implement a plurality of drive assist functions, respectively. The plurality of drive assist devices includes a first drive assist device, which includes an update information generation device configured to generate update information to update a middle point in steering control performed by at least one of the drive assist devices, and a second drive assist device which does not include the update information generation device. The update information generation device in the first drive assist device generates the update information when the first drive assist device receives a notification that permits updating the middle point. The second drive assist device receives the update information from the first drive assist device when the second drive assist device receives the notification.

Abstract: A control device includes one or more processors that is configured to: receive a plurality of first requests from a driver assistance system; arbitrate the plurality of first requests; calculate a second request, which has a physical quantity different from the first request, based on an arbitration result; and distribute the second request to at least one of a plurality of actuator systems. When a difference between the second request based on a previous arbitration result and the second request based on a current arbitration result is larger than a threshold value, the one or more processors are configured to distribute a request that is a value between the second request based on the previous arbitration result and the second request based on the current arbitration result.

Abstract: A braking and driving force control device includes a target braking and driving force calculation unit, and a braking and driving force distribution unit. The braking and driving force distribution unit causes a driving device to generate a target braking and driving force in a case where the target braking and driving force is within the availability, and in a case where the target braking and driving force is less than a lower limit value of the availability, causes the driving device to generate a braking and driving force corresponding to the lower limit value of the availability, performs arithmetic processing of suppressing time variation on the lower limit value of the availability, and causes a braking device to generate a braking force corresponding to a difference between the lower limit value of the availability after the arithmetic processing and the target braking and driving force.
