9. A computer program product comprising a program that causes a processor to function as: an object detection unit that detects an object existing in the periphery of the vehicle; a first notification unit that notifies a driver of the vehicle by a voice or a sound other than a voice; A second notification unit for notifying the driver by a means other than the voice and the sound, and A determining unit that determines a notification order of the first notifying unit and the second notifying unit based on a degree of risk of the object contacting the vehicle detected by the object detecting unit, The first notifying unit and the second notifying unit notify the user in the notifying order determined by the determining unit.

Description

Vehicle notification device, control method for vehicle notification device, and computer program product Technical Field The invention relates to a vehicle notification device, a control method of the vehicle notification device, and a computer program product. Background Conventionally, a technique of notifying a driver of a vehicle is known. For example, patent document 1 discloses an information presentation system that transmits information by the feel of a driver. The information presentation system disclosed in patent document 1 discloses that the priority of the sense of presenting information with respect to the sense of sight, hearing, and touch is determined based on driver information, which is a state such as drowsiness, environmental information such as traffic jams, and the like. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2020-095421 Disclosure of Invention Problems to be solved by the invention However, it is assumed that when the fellow passenger notifies the driver of the vehicle that an object is present in the vicinity of the vehicle, different stimuli are given in different orders according to the degree of risk of the vehicle coming into contact with the object. For example, it is envisaged that in the event that the degree of risk of the vehicle coming into contact with the object is low, the co-operator will communicate to the driver the presence of the object in speech, and then indicate the position of the object with a finger. In this example, the driver is given stimulus in the order of auditory stimulus and visual stimulus by the fellow passenger. For example, when the degree of risk of contact between the vehicle and the object is high, it is assumed that the driver hits the shoulder of the driver to promptly notice the object, then instructs the position of the object with a finger, and then transmits the presence of the object to the driver in a language. In this example, the driver is given a stimulus in the order of tactile stimulus, visual stimulus, and auditory stimulus. As in these examples, it is contemplated that the fellow passenger may impart different stimuli to the driver in different orders depending on the degree of risk of the vehicle coming into contact with the object. Therefore, when an object is notified by feel as in patent document 1 that an object is present in the vicinity of the vehicle, it is preferable to consider the degree of risk of contact. This is to enable notification that the driver does not feel offensive. But no structure exists to enable this notification. Accordingly, an object of the present invention is to suppress a driver from feeling offensive to a notification that an object is present in the vicinity of a vehicle. Furthermore, further improvements in traffic safety are facilitated and the development of sustainable conveying systems is facilitated. Means for solving the problems A vehicle notification device includes an object detection unit that detects an object existing in the vicinity of a vehicle, a first notification unit that notifies a driver of the vehicle of the presence of the object in the vicinity of the vehicle by sound or voice, a second notification unit that notifies the driver of the presence of the object in the vicinity of the vehicle by a means other than sound or voice, and a determination unit that determines a notification order of the first notification unit and the second notification unit based on a degree of risk of the object being in contact with the vehicle detected by the object detection unit, wherein the first notification unit and the second notification unit notify the notification order determined by the determination unit. Effects of the invention According to one aspect of the present invention, it is possible to suppress the driver from feeling offensive to the notification that an object is present in the vicinity of the vehicle.
