Operation unit for vehicle air conditioner and vehicle air-conditioning control apparatus using the same
First Claim
1. An operation unit for a vehicle air conditioner, comprising:
- a display device including a dial calibrated such that a present set value of a control parameter other than a set temperature of the air conditioner is directly readable, a pointer rotatably disposed on the dial, and a pointer driving motor for rotatably driving the pointer;
a setting input portion operable to set a set value of the control parameter;
a determining unit obtaining the present set value of the control parameter and determining a change of the present set value of the control parameter;
an operating state identification unit identifying whether an air-conditioning operating state is in one of a plurality of predetermined operating states of the air conditioner; and
a pointer operation control unit controlling an operation of the pointer driving motor such that the pointer moves on the dial at different moving velocities according to the one air-conditioning operating state, wherein the pointer moves to a position corresponding to the set value of the control parameter with a time lag after the determining unit determines the change of the present set value of the control parameter.

Abstract
An operation unit for a vehicle air conditioner includes a display device, a setting input portion of a control parameter of the air conditioner other than a set temperature, an obtaining portion configured to obtain a present set value of the control parameter, and an operating state identification portion configured to identify whether an air-conditioning operating state is in a plurality of predetermined operating states of the air conditioner. In the operation unit, a moving pattern of a pointer of the display device is changed according to the operating state of the air conditioner. For example, a pointer operation control portion can be configured to control an operation of a pointer driving motor such that the pointer moves on a dial of the display device at different moving speeds according to the air-conditioning operating state.
