Communication control device, communication control method, and storage medium for communication control

A communication control method performed by a processor in a vehicle for controlling communication between the vehicle and a communication management device outside the vehicle, the communication control method comprising:

• calculating at least two types of requested bandwidth including a required bandwidth required for execution of a specific process in the vehicle and a desired bandwidth greater than the required bandwidth, as a communication bandwidth requested for execution of a specific process in the vehicle, based on a sensing capability of the vehicle;
• requesting the communication management device to secure the requested bandwidth;
• and
• defining a utilization bandwidth from the at least two types of the requested bandwidth, which is the communication bandwidth used by the vehicle, based on a response to a request for securing the requested bandwidth, wherein
• in the calculating, the requested bandwidth is calculated based on a difference between required surrounding environment information that is required for continuous processing of an autonomous travel of the vehicle, and acquired surrounding environment information that is acquired by a sensor mounted on the vehicle, the required surrounding environment information corresponding to a relationship between a type of the sensor and a traveling environment of the vehicle, and
• in the defining, the utilization bandwidth is defined in accordance with the response in which the requested bandwidth is available to be secured from the at least two types of the requested bandwidth.

A non-transitory computer readable medium storing a communication control program including instructions configured to, when executed by a processor in a vehicle, cause the processor to:

• calculate at least two types of requested bandwidth including a required bandwidth required for execution of a specific process in the vehicle and a desired bandwidth greater than the required bandwidth, as a communication bandwidth requested for execution of a specific process in the vehicle, based on a sensing capability of the vehicle;
• request a communication management device outside the vehicle to secure the requested bandwidth;
• and
• define a utilization bandwidth from the at least two types of the requested bandwidth, which is the communication bandwidth used by the vehicle, based on a response to a request for securing the requested bandwidth, wherein
• the requested bandwidth is calculated based on a difference between required surrounding environment information that is required for continuous processing of an autonomous travel of the vehicle, and acquired surrounding environment information that is acquired by a sensor mounted on the vehicle, the required surrounding environment information corresponding to a relationship between a type of the sensor and a traveling environment of the vehicle, and
• the utilization bandwidth is defined in accordance with the response in which the requested bandwidth is available to be secured from the at least two types of the requested bandwidth.
