An information processing apparatus includes a receiver configured to receive a data set including a requested acceleration as information representing movement of a vehicle in a front-rear direction and any one of a steering angle, a yaw rate, and a rotation radius as information representing movement of the vehicle in a lateral direction from each of a plurality of applications, an arbitration unit configured to perform arbitration of information representing the movement of the vehicle in the front-rear direction and arbitration of information representing the movement of the vehicle in the lateral direction based on a plurality of the data sets received by the receiver, and a first output unit configured to output instruction information for driving an actuator based on an arbitration result of the arbitration unit.

The maximum speed informing device includes a camera device that acquires image data by capturing a scene in front of the vehicle, a display unit configured to be able to display the maximum speed, and a controller configured to be able to change the maximum speed displayed on the display unit, the controller acquires a numerical value included in the captured scene as a maximum speed candidate based on the image data, acquires road structure information indicating a structure of a road including a lane on which the vehicle is traveling based on the image data, estimates a range of a maximum speed of the road based on the acquired road structure information, and displays the maximum speed candidate within the estimated maximum speed range as the maximum speed on the display unit.
