  "textContent": "A motor generator control unit controls operation of a motor generator which generates power using a driving force transmitted from an engine. A charge/discharge control unit electrically connects a first capacitor and a second capacitor and controls charging/discharging of power between the first capacitor and the second capacitor in response to an externally supplied control signal. A motor which is electrically connected to the second capacitor is capable of regenerating electric energy and storing the regenerated energy in the second capacitor. A control device supplies a control signal to at least one of the motor generator control unit and the charge/discharge control unit and reduces a target charging value of at least one of the first capacitor and the second capacitor before the motor regenerates energy.",
