To execute charging control appropriate for the current vehicle weight even when the vehicle weight changes.SOLUTION: A vehicle comprises: an engine; a power generator that generates power by using power output from the engine; a power storage device that charges power generated by the power generator; a motor for driving the vehicle, which is driven using at least one of power discharged by the power storage device and power generated by the power generator; a control unit that controls charging of the power storage device; and a weight estimation unit that estimates the weight of the vehicle during travel of the vehicle. The control unit is configured such that when SOC of the power storage device has decreased to a charging start SOC or below during travel of the vehicle with the motor, the engine is operated to start charging the power storage device with the power generator and, when the SOC of the storage device has reached a charging completion SOC or above, the engine is stopped to stop charging of the power storage device as well. The charging completion SOC (k12) is set according to the weight of the vehicle, estimated by the weight estimation unit.SELECTED DRAWING: Figure 7
【課題】車両重量が変化しても、現在の車両重量に適した充電制御を行なう。【解決手段】車両が、内燃機関と、内燃機関から出力される動力を利用して発電を行なう発電機と、発電機による発電電力を充電する蓄電装置と、蓄電装置の放電電力および前記発電機による発電電力のうちの少なくとも一方の電力を用いて駆動される車両駆動用の電動機と、蓄電装置の充電制御を行なう制御部と、車両走行中に車両重量を推定する重量推定部とを備える。そして、制御部は、電動機による車両走行中に、蓄電装置のSOCが充電開始SOC以下になった場合に内燃機関を運転して発電機による蓄電装置への充電を開始し、蓄電装置のSOCが充電完了SOC以上になった場合に内燃機関を停止させて蓄電装置への充電を停止させるように構成される。充電完了SOC(k12)は、重量推定部によって推定された車両重量に応じて設定される。【選択図】図7
