In-vehicle control device, information processing device, vehicle network system, method of providing application program, and recording medium with program recorded thereon

An information processing device comprising:

• an extravehicular communication unit configured to perform communication with a vehicle-side communication unit provided at an in-vehicle control device installed on a vehicle;
• and
• a processor, the processor being configured to:
• make an installation request for an application program to the in-vehicle control device,
• collect a rule defining whether or not a communication frame received at the vehicle-side communication unit is unauthorized and equipment information related to optional equipment of the vehicle from the in-vehicle control device to which the installation request was made,
• generate a rule that has been updated based on the collected rule and the equipment information, and
• provide the application program and the generated updated rule to the in-vehicle control device.

A method of providing an application program to an in-vehicle control device installed on a vehicle from an information processing device external to the vehicle, the method comprising:

• making an installation request, from the information processing device to the in-vehicle control device, for the application program;
• notifying, from the in-vehicle control device, the information processing device of a rule defining whether or not a communication frame received at a communication unit provided at the in-vehicle control device is unauthorized and of equipment information related to optional equipment of the vehicle;
• generating an updated rule based on the rule and the equipment information acquired at the information processing device;
• providing, from the information processing device to the in-vehicle control device, the application program and the updated rule;
• in a case in which the application program has been acquired at the in-vehicle control device, installing the application program;
• in a case in which the updated rule has been acquired at the in-vehicle control device, updating the rule to the updated rule;
• and
• after the updating to the updated rule, executing the application program.

A non-transitory storage medium storing a program for causing a computer to execute processing such that an in-vehicle control device, installed on a vehicle and performing communication with at least an information processing device external to the vehicle, receives a provided application program, the processing comprising:

• receiving, from the information processing device, an installation request for an application program;
• in a case in which the installation request has been received, notifying the information processing device of a rule defining whether or not a communication frame received at a communication unit provided at the in-vehicle control device is unauthorized and of equipment information related to optional equipment of the vehicle;
• acquiring the application program, and a rule that has been updated based on the notified rule and the equipment information, from the information processing device;
• and
• in a case in which the updated rule has been acquired at the in-vehicle control device, updating the rule to the updated rule.

A non-transitory storage medium storing a program for causing a computer to execute processing such that an extravehicular information processing device provides an application program to an in-vehicle control device installed on a vehicle, the processing comprising:

• making an installation request for an application program to the in-vehicle control device,
• collecting a rule defining whether or not a communication frame received at a communication unit provided at the in-vehicle control device is unauthorized and equipment information related to optional equipment of the vehicle from the in-vehicle control device to which the installation request was made,
• generating a rule that has been updated based on the collected rule and the equipment information, and
• providing the application program and the updated rule to the in-vehicle control device.
