Abstract: A semiconductor device capable of charging that is less likely to cause deterioration of a power storage device is provided. The amount of a charging current is adjusted in accordance with the ambient temperature. Charging under low-temperature environments is performed with a reduced charging current. When the ambient temperature is too low or too high, the charging is stopped. Measurement of the ambient temperature is performed with a memory element using an oxide semiconductor. The use of a memory element using an oxide semiconductor enables measurement of the ambient temperature and retention of the temperature information to be performed at the same time.

Abstract: The vehicle control device executes: a stop process for stopping fuel supply to two cylinders to be stopped; and a selection process of selecting one cylinder to be a stop instruction for stopping fuel supply from among the cylinders to be stopped. The selection process is a process of selecting a cylinder whose compression top dead center appears earliest among the stop target cylinders. The crank angle interval from when the cylinder to be the stop instruction target is selected until the stop instruction target cylinder is switched to the next cylinder among the stop target cylinders is the stoppable angle interval. The stop instruction for the selected cylinder is received before the fuel injection start time and at the stoppable angle interval. The control device executes a retard process of retarding the fuel injection start timing so that the stoppable angle interval includes the fuel injection start timing.
