Use recommendation apparatus and vehicle

A use recommendation apparatus configured to be applied to a vehicle, the use recommendation apparatus comprising:

• acquiring circuitry configured to acquire
• sensor data to be acquired from a sensor of the vehicle when a subject is driving the vehicle,
• traffic data on a surrounding environment around the vehicle to be acquired when the subject is driving the vehicle, and
• non-traffic data comprising one or more of:
• usage data to be recorded in a user terminal upon a use of the user terminal by the subject;
• passenger data on a passenger of the vehicle to be acquired when the subject is driving the vehicle;
• and action data on an action of the subject to be acquired when the subject is not driving the vehicle;
• and
• processing circuitry configured to process the sensor data, the traffic data, and the non-traffic data acquired by the acquiring circuitry, wherein
• the processing circuitry is configured to
• generate a degree of necessity of a recommendation of a use of a predetermined operation device, based on the sensor data, the traffic data, and the non-traffic data,
• select, when the degree of necessity is greater than or equal to a first threshold and less than or equal to a second threshold, a predetermined pacing model from a plurality of pacing models, based on the sensor data, the traffic data, and the non-traffic data,
• acquire, from the predetermined pacing model, a first recommendation sentence having undergone predetermined pacing processing as a recommendation sentence that recommends the use of the predetermined operation device by inputting the sensor data, the traffic data, and the non-traffic data to the predetermined pacing model, and
• output the first recommendation sentence.
