Abstract: When a microcomputer does not charge an electric storage device, the microcomputer activates at an interval set based on a timer set value and determines whether an electric power voltage generated by a solar cell is equal to or higher than an electric power generation determination threshold. When the generated electric power voltage is lower than the electric power generation determination threshold, the microcomputer turns to a sleep state after increasing the timer set value by an addition set value while prohibiting charging the electric storage device. When the generated electric power voltage is equal to or higher than the electric power generation determination threshold and a generated electric power amount is equal to or larger than an electric power generation determination threshold, the microcomputer starts charging the electric storage device so the electric power device can be appropriately charged with an electric power generated by the solar cell.

Abstract: When a steering intervention of the driver is performed during automated steering control, a driver assistance system for a vehicle determines a P control amount based on a non-linear characteristics and calculates an I control amount using a coefficient according to a characteristics (solid line). In an angle difference range R1, the P control amount based on the non-linear characteristics is determined such that the amount of increase of absolute value of the P control amount with respect to the amount of increase of absolute value of the angle difference becomes smaller as compared to a linear characteristics. The coefficient with the characteristics (solid line) indicates 1 in the angle difference range R1, and approaches zero when the absolute value of the angle difference is greater in an angle difference range R2. To calculate the I control amount, the coefficient is multiplied by the current value of the angle difference.

Abstract: An internal combustion engine 100 comprises an air-fuel ratio control device. The air-fuel ratio control device controls the amount of fuel fed to the combustion chamber by feedback control so that the air-fuel ratio detected by the upstream side air-fuel ratio sensor matches the target air-fuel ratio when a blow-through amount of air blown from the intake passage through a cylinder to the exhaust passage due to an occurrence of valve overlap is a reference blow-through amount or less. The air-fuel ratio control device sets the target air-fuel ratio of the inflowing exhaust gas based on the air-fuel ratio detected by the downstream side air-fuel ratio sensor and, without performing the feedback control, feeds the amount of fuel calculated from the target air-fuel ratio to the combustion chamber when the blow-through amount is greater than the reference blow-through amount.
