VEHICLE AIR CONDITIONER
First Claim
1. An air conditioner for a vehicle including an electric motor for traveling and an internal combustion engine as a driving source for outputting a driving force for traveling of the vehicle, the vehicle having a first operation mode in which an internal combustion engine-side driving force output from the internal combustion engine is more than a motor-side driving force output from the electric motor for traveling, and a second operation mode in which the motor-side driving force is more than the internal combustion engine-side driving force, as an operation mode for the vehicle, the air conditioner comprising:
- a heater which heats air to be blown into a vehicle interior using a coolant of the internal combustion engine as a heat source; and
a request signal output device, which outputs a request signal for increasing the number of revolutions of the internal combustion engine to a driving force controller for controlling an operation of the internal combustion engine, during a heating operation of the vehicle interior,wherein the request signal output device outputs as the request signal, a signal that makes the number of revolutions increased in the second operation mode higher than that increased in the first operation mode.

Abstract
An air conditioner is applied to a vehicle having a first operation mode in which an internal combustion engine-side driving force is more than a motor-side driving force, and a second operation mode in which the motor-side driving force is more than the internal combustion engine-side driving force, as an operation mode for the vehicle. The air conditioner includes a heater for heating air using a coolant of an internal combustion engine as a heat source, and a request signal output portion for outputting a request signal for increasing the number of revolutions of the internal combustion engine to a driving force controller during a heating operation of the vehicle interior. The request signal output portion outputs as the request signal, a signal that makes the number of revolutions increased in the second operation mode higher than that increased in the first operation mode.

6. An air conditioner for a vehicle including an electric motor for traveling and an internal combustion engine as a driving source for outputting a driving force for traveling of the vehicle, the vehicle having a first operation mode in which an internal combustion engine-side driving force output from the internal combustion engine is more than a motor-side driving force output from the electric motor for traveling, and a second operation mode in which the motor-side driving force is more than the internal combustion engine-side driving force, as the operation mode for the vehicle, the air conditioner comprising:
-
a heater which heats air to be blown into a vehicle interior using a coolant of the internal combustion engine as a heat source; and a request signal output device, which outputs a request signal for decreasing a driving force ratio of the internal combustion engine-side driving force to the motor-side driving force, to a driving force controller for controlling operations of the internal combustion engine and the electric motor for traveling, when a heating operation of the vehicle interior is performed in the second operation mode. - View Dependent Claims (7, 8, 9, 10)

11. An air conditioner for a vehicle including an electric motor for traveling and an internal combustion engine as a driving source for outputting a driving force for traveling of the vehicle, the vehicle having a first operation mode in which an internal combustion engine-side driving force output from the internal combustion engine is more than a motor-side driving force output from the electric motor for traveling, and a second operation mode in which the motor-side driving force is more than the internal combustion engine-side driving force, as the operation mode for the vehicle, the air conditioner comprising:
-
a heater which heats air to be blown into a vehicle interior using a coolant of the internal combustion engine as a heat source; and a request signal output device, which outputs a request signal for requesting a driving force controller to perform switching into the first operation mode when a predetermined condition is satisfied during a heating operation of the vehicle interior in the second operation mode, the driving force controller being adapted to control operations of the internal combustion engine and the electric motor for traveling. - View Dependent Claims (12, 13, 14, 15, 16, 17)
