The vapor compression refrigerating device further comprises a heating cycle (a heat pump cycle, or a hot gas cycle) for performing a heating operation to engine cooling water by using the high temperature and high pressure refrigerant from a compressor device, wherein a control means activates the heating cycle at a predetermined time before starting an engine when an outside air temperature is lower than a predetermined value. Accordingly, the engine has been already warmed up before a driver gets into the vehicle.

Each time that starting of a vehicle engine is completed, a vehicle control system derives an estimated amount by which the charge in the vehicle battery is less than a predetermined upper limit value of stored charge, and subtracts the estimated amount from the difference between the upper limit value and a lower limit value of stored charge, to obtain an initial allowable discharge amount. An automatic engine stop/restart function is thereafter enabled or inhibited in accordance with whether a net amount of discharge from the battery, to since completion of the preceding engine start, exceeds the initial allowable discharge amount.

In an electrical powered vehicle including a control device for generating an input/output power command value for a power storage device and a control device for controlling a power conversion device and a rotating electric machine, provided separately, when there is a sudden change in the rotational speed of a rotating electric machine, the input/output power command value of a power storage device intrinsically set by an HV-ECU is corrected corresponding to the change in the rotational speed of the rotating electric machine by a control device MG-ECU detecting the rotational speed of the rotating electric machine, without having to wait for modification of the input/output power command value from the HV-ECU. Accordingly, there can be prevented excessive charging and excessive discharging of a power storage device induced by delay in modifying the input/output power command value caused by transmission delay between control devices when the rotational speed of the rotating electric machine suddenly changes.

SOC of the battery is determined from an established relationship between battery voltage and SOC when battery current is zero for at least a predetermined time period and SOC is also determined from an established relationship between battery voltage, current and SOC when discharge current is constant for at least a predetermined time period. SOC of the battery is revised on every chance battery current is zero or constant for at least the predetermined time period, and SOC at any point of time in operation of the forklift truck is estimated by integrating battery current from the time point of SOC revision and subtracting the integrated current from said revised SOP. Allocation of drive power of the engine and motor generator is performed in accordance with an established relationship between permissible discharge and charge current and SOC of the battery so that excessive exhaustion or excessive charging of the battery does not occur.
