Information processing device for vehicle, and information processing system

An information processing system, comprising:

• one or more processors installed in a vehicle;
• and
• a server configured to perform wireless communication with the one or more processors, wherein
• the one or more processors are configured to execute:
• acquiring vehicle driving force that is driving force of the vehicle;
• acquiring inertial resistance that is an apparent resistance force with respect to motion of the vehicle;
• acquiring position coordinates of a point at which the vehicle is situated;
• acquiring gradient resistance that is a resistance force due to a gradient at the point at which the vehicle is situated;
• calculating traveling resistance that is a value obtained by subtracting the inertial resistance and the gradient resistance from the vehicle driving force;
• and
• externally transmitting, from the vehicle, data including the position coordinates, and the traveling resistance calculated based on the vehicle driving force at the position coordinates, the inertial resistance at the position coordinates, and the gradient resistance at the position coordinates, as collected data;
• and
• the server is configured to execute:
• acquiring the collected data;
• determining whether an abnormality is present on a road at the position coordinates included in the collected data, based on the traveling resistance included in the collected data;
• and
• wherein the one or more processors of the vehicle are configured to further execute:
• acquiring a vehicle speed of the vehicle;
• and
• acquiring a rotational speed of each of a plurality of wheels that the vehicle is equipped with;
• wherein the collected data includes the vehicle speed at the position coordinates and the rotational speed of each of the wheels at the position coordinates, and
• the server is configured to further execute:
• identifying that the abnormality is present on the road at the position coordinates included in the collected data, and that a type of the abnormality is becoming stuck due to snow, under a condition that an amount of increase in the traveling resistance included in the collected data is no less than a stipulated resistance value, and also an absolute value of difference between a maximum value and a minimum value of the rotational speed of each wheel included in the collected data is no less than a stipulated difference,
• acquiring position coordinates of a point at which another vehicle is situated, and
• determining whether the another vehicle is within a preset distance from the vehicle, and in response to determining that the another vehicle is within the preset distance from the vehicle, generating road information indicating that the abnormality is present on the road and transmitting the road information to the another vehicle,
• wherein another set of one or more processors of the another vehicle are configured to display the road information on a display.
