摘要： A battery-temperature raising apparatus includes a battery, a transmission, an oil pan, a heat-retaining oil tank, a heat exchanger, a first valve, a temperature sensor, and a control unit. The transmission includes a transmission mechanism that converts torque and a clutch capable of braking a wheel. The oil pan and the oil tank are disposed in the transmission and are in communication with the heat exchanger that exchanges heat between the battery and oil. The first valve opens and closes a path joining the oil tank and the heat exchanger. The control unit generates braking force by controlling engagement force of the clutch depending on an amount of depression of a brake pedal. The control unit supplies the oil stored in the oil tank to the heat exchanger by opening the first valve when a temperature of the battery detected by the temperature sensor is below a predetermined temperature.

摘要： Disclosed herein a method for upshifting the transmission of a vehicle using shift entry prediction. The method may comprise predicting whether or not an upshift request of a vehicle will occur, determining whether or not a charge demand required for a battery through regeneration for upshift is greater than an allowable charge amount of the battery when the upshift request is predicted, controlling power consumption of the battery when the charge demand is greater than the allowable charge amount, and processing the upshift in response to an actual request of the upshift.

摘要： A vehicle control device includes a processor and memory. The memory stores relation-defining data for defining a relation between a state of a vehicle and an action variable that is a variable relating to operations of a transmission installed in the vehicle. The processor is configured to execute acquisition processing, operation processing, reward calculation processing, updating processing, counting processing, and limiting processing. The processor is configured to output the relation-defining data updated so that an expected income is increased when the transmission is operated following the relation-defining data, based on an updating map.
