Abstract: A catalyst temperature estimation device that estimates a temperature of a catalyst provided in an exhaust passage of an internal combustion engine includes a storage device and processing circuitry. The storage device stores mapping data that specifies a mapping that uses multiple input variables to output an estimation value of the temperature of the catalyst. The multiple input variables include at least one variable of an ambient temperature variable or an excess amount variable. The multiple input variables further include a fluid energy variable, which is a state variable related to energy of fluid flowing into the catalyst, and a previous cycle value of the estimation value of the temperature of the catalyst. The processing circuitry is configured to execute an acquisition process, a temperature calculation process, and an operation process. The mapping data includes data that is learned through machine learning.

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, an updating process that updates relationship defining data. The update map outputs the updated relationship defining data so as to increase an expected return for the reward in a case where the electronic device is operated in accordance with the relationship defining data. The reward calculating process includes a changing process that changes the reward between when the characteristic of the vehicle is a predetermined characteristic in an EV mode and when the characteristic is the predetermined characteristic in a HV mode.

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.

Abstract: A vehicle controller is used for a first vehicle and includes processing circuitry. The processing circuitry is configured to execute an index deriving process that derives a traveling performance index of the first vehicle, the traveling performance index being an index related to a traveling performance, an index receiving process that receives the traveling performance index of a second vehicle from the second vehicle through vehicle-to-vehicle communication, and a performance determination process that compares the traveling performance index of the second vehicle with the traveling performance index of the first vehicle to determine whether a traveling performance of the first vehicle is lower than a traveling performance of the second vehicle.

Abstract: A controller transmits a fuel-economy variable, which corresponds to a travelled distance by a unit fuel amount, to a vehicle group managing device. When the fuel-economy variable is greater than or equal to a reference value, the vehicle group managing device determines that a user is a good driver. When updating software installed in the controller, the vehicle group managing device discounts the billing amount for purchasing the updated version of the software.

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.

Abstract: A learned neural network learned in weights using an engine load, an engine speed, and an intake pressure inside the engine intake passage downstream of the throttle valve (19) as input parameters of the neural network and using leakage of blow-by gas from a blow-by gas feed path (20) as a truth label is stored. At the time of operation of the vehicle, the learned neural network is used to detect the abnormality of leakage of blow-by gas from the blow-by gas feed path (20) from the above input parameters.

Abstract: A supply information communication system, a communication module, a liquid supply facility, and a supply information communication method are provided. The communication module is mounted on a vehicle to which liquid is supplied from the liquid supply facility. An obtaining section of the liquid supply facility obtains identifying information for identifying the vehicle that is a supply destination of the liquid discharged by a supplying section. A transmitting section of the liquid supply facility transmits supply information to the vehicle identified by the identifying information. The supply information includes information indicating that the liquid has been supplied. The communication module includes a receiving section and a storing section. The receiving section receives the supply information addressed to the vehicle on which the communication module is mounted. The storing section stores the received supply information.

Abstract: A state detection system for an internal combustion engine is provided. Rotation waveform variables include information on a difference between cylinders in the rotational speed of a crankshaft during periods in which the respective cylinders generate combustion torque. An obtainment process obtains a value of the rotation waveform variables and a value of a road surface state variable based on an output of a sensor that detects a state of the road surface. A selection process selects, from a plurality of types of mapping data stored in the storage device, the mapping data that is associated with the road surface state variable as the detection mapping. A determination process determines whether the engine is in a predetermined operating state based on an output value of the selected detection mapping that takes the rotation waveform variables as inputs.
