  • Patent number: 11226034
    Abstract: A CPU sets a gear ratio, which is an action, on the basis of an accelerator operation amount, a vehicle speed, a gradient, a curvature, and a current gear ratio, until a predetermined amount of time elapses. The CPU operates a transmission in accordance with the set gear ratio and obtains a rotation speed NE of a crankshaft at that time. When the predetermined amount of time has elapsed, the CPU updates an action value function by providing a reward in accordance with whether the number of times of switching the rotation speed NE or the gear ratio meets a standard.

  • Publication number: 20210255061
    Abstract: In a method for learning a mapping used by a computer, the mapping calculates a probability related to a categorization result using an internal combustion engine state variable as an input. The categorization result is a result of categorizing a state of an internal combustion engine into one of regions. The computer outputs the categorization result based on the calculated probability. The method includes inputting multiple training data to a training computer. The training data include the internal combustion engine state variable and the categorization result that is correct and associated with the internal combustion engine state variable. The method further includes updating the mapping based on the training data with the training computer. The training data are distributed to the regions and have a distribution density that is increased at locations closer to a border between the regions.
