  • Publication number: 20210231092
    Abstract: A CPU mounted on a vehicle obtains positional data by the GPS. Next, the CPU identifies an octane number, which is a parameter related to combustion of fuel, on the basis of the positional data corresponding to the position of the vehicle and the date and time at which the positional data was obtained. Then, the CPU calculates a correction amount on the basis of the identified parameter. The CPU assigns, to ignition timing, a value calculated on the basis of the correction amount. The CPU controls an ignition device so that the ignition device generates spark discharge at the calculated ignition timing.

  • Publication number: 20210229687
    Abstract: A vehicle controller, a vehicle control system, a vehicle control method, and a vehicle control system control method are provided. An internal execution device of the vehicle controller detects that learning data stored by an internal memory device due to the occurrence of an anomaly in a vehicle. The internal execution device transmits, to the outside of the vehicle, a request signal that requests for previously-learned learning data, where learning is performed from an initial state of the learning data. The internal execution device causes the internal memory device to store the received previously-learned learning data instead of the reset learning data.

  • Publication number: 20210213975
    Abstract: A vehicle control data generation method is provided. A self-driving mode of a vehicle automatically generates a command value of a propelling force produced by a propelling force generator independently of an accelerator operation. An execution device provides a greater reward based on an obtained state of the vehicle when a standard of a characteristic of the vehicle is met than when the standard is not met. Providing the reward changes a reward that is provided when the characteristic of the vehicle is a predetermined characteristic in the self-driving mode such that the changed reward differs from a reward that is provided when the characteristic of the vehicle is the predetermined characteristic in a manual driving mode.

  • Publication number: 20210189991
    Abstract: A vehicle controller is provided. An update process updates a relationship defining data by inputting, to a predetermined update map, a state of a vehicle, a value of an action variable used to operate an electronic device, and a reward corresponding to that electronic device. A reward calculating process provides, based on the state of the vehicle obtained by an obtaining process, a greater reward when a characteristic of the vehicle meets a standard than when the characteristic of the vehicle does not meet the standard. A loosening process loosens the standard to a larger extent when the degree of deterioration is large than when the degree of deterioration is small.

  • Publication number: 20210114579
    Abstract: An update process updates relationship defining data by inputting, to a predetermined update map, a state of a vehicle obtained by a state obtaining process, a value of an action variable used to operate an electronic device, and a reward corresponding to an operation of an electronic device. A range in which an operation process uses, as the action variable, a value different from a value that maximizes an expected return related to the reward is defined as a return non-maximizing range. In a case in which a degree of deterioration of the vehicle is greater than or equal to a predetermined degree, a changing process changes the return non-maximizing range to a side on which the return non-maximizing range is expanded as compared to a case in which the degree of deterioration is less than the predetermined degree.
