Claims

[Scope of utility model registration request]

In a vehicle air conditioning control system having an externally controllable variable displacement compressor, a control target value is calculated according to a detection value of a display means capable of displaying the discharge capacity of the compressor and a heat load detection means. a display control means capable of controlling the display of the display means in accordance with a control output to the capacity control means of the compressor based on the calculation result of the calculation means; a selection switch for automatic control mode; mode selection determining means for determining which of the control mode selection switches has been selected; and according to the result of the determination,
When the dry control mode is selected, the display control means is controlled to perform a predetermined increase correction of the discharge volume and to switch the display mode of the display means to a constant display means indicating a large discharge volume regardless of changes in the discharge volume. What is claimed is: 1. A vehicle air conditioning control device, comprising: a correction control means for controlling the vehicle;
