Abstract: A controller includes a memory device and an execution device, which executes an operation of an operated unit of an internal combustion engine. The execution device executes a first calculation process that uses adapted data sets in order to calculate an operated amount on the basis of a detected value of a state variable, a second calculation process that calculates, as the operated amount, a value that is determined by a relationship defining data set and the state variable, a reinforcement learning process that updates the relationship defining data set, first and operation processes that operate the operated unit in accordance with a calculated value of the operated amount, and a switching process that switches a process that operates the operated unit between the first operation process and the second operation process in accordance with the state of the vehicle.

Abstract: A vehicle control data generation method is provided. A preference variable indicates a relative preference of a user for two or more requested elements that include at least two of three requested elements including a requested element indicating a high acceleration response of a vehicle, a requested element indicating at least one of vibration and noise of the vehicle is small, and a requested element indicating a high energy use efficiency. The reward calculating process includes a changing process that changes a reward provided when a characteristic of the vehicle is a predetermined characteristic in a case where a value of the preference variable is a second value such that the changed reward differs from the reward provided when the characteristic is the predetermined characteristic in a case where the value of the preference variable is a first value.

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.

Abstract: A vehicle control device includes a memory configured to store relationship definition data that defines a relationship between a state of a vehicle and an action variable, which is a variable relating to an operation of electronic equipment in the vehicle, and a processor. The processor is configured to execute acquisition processing of acquiring a detection value of a sensor and driving preference information, operation processing of operating the electronic equipment, reward calculation processing of providing a greater reward when a characteristic of the vehicle satisfies a criterion than when the characteristic of the vehicle does not satisfy the criterion, and update processing of updating the relationship definition data. The processor is configured to, based on update mapping, output the relationship definition data updated to increase an expected return on the reward when the electronic equipment is operated in compliance with the relationship definition data.

Abstract: A method of generating vehicle control data is provided. The method is executed using a processor and a storage device and includes: storing first data that prescribe a relationship between a state of a vehicle and an action variable that indicates an action related to an operation of an electronic device; acquiring a detection value from a sensor that detects the state of the vehicle; operating the electronic device; calculating a reward, on the basis of the acquired detection value; in a case where a predetermined condition is met, updating the first data using, as inputs to update mapping determined in advance, the state of the vehicle, a value of the action variable, and the reward; and in a case where the state of the vehicle does not meet the predetermined condition, obtaining second data by adapting the relationship between the state of the vehicle and the action variable.

Abstract: An internal combustion engine condition determination apparatus includes a storage device; and an execution device. The storage device stores mapping data that defines a mapping. The execution device is configured to execute an acquisition process of acquiring an internal combustion engine state variable every time a crankshaft of an internal combustion engine rotates by a predetermined angle, and a determination process of determining a condition of the internal combustion engine based on an output obtained through the mapping using the internal combustion engine state variable as an input. The mapping data is trained by machine learning. The execution device is configured to prohibit the determination process when a rotation speed of the crankshaft is equal to or higher than a predetermined threshold.
