Control Apparatus for Vehicle and Control Method for Vehicle

摘要

An electronic control unit is configured to: i) calculate a restriction target value of input electric current to a battery depending on detection value of a current sensor, in a charge control of charging the battery such that charging electric power to the battery is below a permissible value, ii) calculate voltage value of the battery when the battery is charged based on the restriction target value, in a case where the detection value exceeds the restriction target value, iii) calculate a basic permissible value of the charging electric power to the battery, from the restriction target value and the voltage value, and iv) set a regeneration restriction rate to a higher value, as a difference value between the restriction target value and the detection value increases, or as at least one of vehicle speed and the charging electric power when the detection value exceeds the restriction target value increases.
