Abstract: The power storage cell includes a wound electrode body, a case, an internal gasket (a seal member), a positive electrode terminal (an external terminal), and a positive electrode connecting portion (a connecting member). The case includes a peripheral wall portion, a lower lid (first lid portion), and an upper lid (second lid portion). The lower lid has an exhaust valve for exhausting the gas in the case. A through hole (second through hole) is formed in the upper lid (second lid). The positive electrode connecting portion includes a columnar portion extending in the Z direction so as to penetrate the through hole of the upper lid and the through hole (first through hole) of the inner gasket. The inner gasket is disposed so as to cover the through hole from the inside of the case.

Abstract: A vehicle control data generation method includes causing processing circuitry to execute an obtaining process that obtains a state of a vehicle and a specifying variable, an operating process that operates an electronic device, a reward calculating process that provides a greater reward when a characteristic of the vehicle meets a standard than when the characteristic does not meet the standard, and an updating process that updates relationship defining data. The update map outputs the updated relationship defining data. The reward calculating process includes a changing process that changes the reward, provided when the characteristic of the vehicle is a predetermined characteristic, such that the reward in a case where torque generated by an internal combustion engine is used to generate the propelling force of the vehicle differs from the reward in a case where the torque is not used to generate the propelling force.

Abstract: A controller includes a memory device and an execution device that executes first and second operation processes, a switching process, and a recording process. The first operation process operates an operated unit by an operated amount, which is calculated on the basis of a state variable, using an adapted data set. The second operation process operates the operated unit by an operated amount that is defined by a relationship defining data set and the state variable. The switching process switches a process that operates the operated unit between the first operation process and the second operation process. The recording process obtains a value of the state variable used in calculation of the operated amount using the first operation process during an operation of the operated unit using the second operation process. The recording process also records time-series data of the obtained value of the state variable in the memory device.

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 includes a first operation process that operates the operated unit by an operated amount, which is calculated on the basis of a state of a vehicle, using an adapted data set, a second operation process that operates the operated unit by an operated amount that is defined by a relationship defining data set and the state of the vehicle, and a switching process that switches the operation of the operated unit between an operation by the first operation process and an operation by the second operation process, depending on whether the vehicle is performing a manual acceleration travel or an automatic acceleration travel.

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.

Abstract: A vehicle controller includes processing circuitry and a storage device. The storage device stores relationship specifying data that specifies a relationship between a state of a vehicle and at least one action variable. The at least one action variable is a variable related to operation of an operating unit of an internal combustion engine. The processing circuitry is configured to execute an obtaining process that obtains a state of the vehicle, an operating process that operates the operating unit based on a value of the at least one action variable, a reward calculation process, an updating process that updates the relationship specifying data, and a determination process that determines whether the internal combustion engine has deteriorated. The determination process is executed on condition that at least one of the at least one action variable equals a predetermined value.

Abstract: A CPU uses relationship-defining data to set a throttle command value and a gear ratio command value on the basis of time-series data of an accelerator operation amount, a vehicle speed, and a gear ratio. The CPU operates a throttle valve and a transmission in accordance with the throttle command value and the gear ratio command value and obtains a rotation speed, a torque, a torque command value, and an acceleration at that time. When a predetermined amount of time is completed, the CPU updates the relationship-defining data by providing a reward depending on whether the torque and the acceleration meet standards. The CPU changes the reward depending on whether a position is a merging point.

Abstract: A vehicle control system is provided. A classification process classifies vehicles into groups based on information related to vehicles. In order to update relationship defining data for each of the classified groups, an update process inputs, into an update map, states of the vehicles belonging to a same group, values of action variables used to operate the electronic devices of the vehicles belonging to the same group, and rewards corresponding to the operation of the electronic devices.

Abstract: A vehicle controller includes processing circuitry and a storage device. The storage device stores relationship specifying data that specifies a relationship between a vehicle state and an action variable. The processing circuitry is configured to execute an obtaining process obtaining the vehicle state, an operating process operating an electronic device based on a value of the action variable, a reward calculation process assigning a reward based on the vehicle state, an updating process updating the relationship specifying data using the vehicle state, the value of the action variable, and the reward as inputs to an update mapping. When a value of the action variable designated by the relationship specifying data is a first value, a process in which the operating process operates the electronic device in accordance with the first value is executable in a first situation and is not executable in a second situation.

Abstract: A vehicle controller, a vehicle control system, a vehicle learning device, a vehicle control method, and a memory medium are provided. A switching process switches relationship defining data used in an operation process to post-measure data, when a detection process detects that a functional recovery measure has been taken. The switching process includes a process that uses, as the post-measure data, initial data that is the relationship defining data of a state before an update process is executed as the vehicle travels.
