Device and method for controlling vehicle

A control device for a vehicle, comprising:

• a compressor for an air-conditioning device that is driven by a vehicle drive source;
• and
• a condenser for the air-conditioning device that is disposed at a front side of the vehicle,
• wherein a request torque to the vehicle drive source is determined as a sum of an air-conditioning load which is spent for driving the compressor and a running torque necessary to drive the vehicle by a drive wheel,
• wherein the running torque is calculated based on an accelerator manipulation of a driver,
• wherein a range-position signal indicating a selected range position is read, and
• wherein a value of the air-conditioning load when the air-conditioning device is in operation and the range position is in a Reverse-range is larger than a value of the air-conditioning load when the range position is in a Drive-range with respect to an identical refrigerant pressure of the air-conditioning device.

• determining a request torque to the vehicle drive source as a sum of an air-conditioning load which is spent for driving the compressor and a running torque necessary to drive the vehicle by a drive wheel, the running torque being calculated based on an accelerator manipulation of a driver;
• reading a selected range position;
• and
• causing a value of the air-conditioning load when the air-conditioning device is in operation and the range position is in a Reverse-range to larger than a value of the air-conditioning load when the range position is in a Drive-range with respect to an identical refrigerant pressure of the air-conditioning device.
