Problems solved by technology

[0003] However, in this conventional automatic air conditioning, since many thermal load detection devices and various temperature control device driving devices are required, and many complicated control systems and equations are used, it takes a lot of time and cost to form the air conditioning control system
[0004] In addition, there is a case where the transient response of the blowing temperature, especially when changing the set temperature, appears as over-regulation or under-regulation, especially if an over-regulation situation occurs that results in an instantaneously high blowing temperature, then there may be a make the driver uncomfortable
Therefore, in the conventional control, since the response difference of the blowing temperature for the vehicle interior temperature is not taken into account, the situation of over-regulation or under-regulation of the vehicle interior temperature occurs

Embodiment Construction

[0019] FIG. 1 shows a schematic structure of a vehicle air conditioner as a control device according to one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a mechanical part of the vehicle air conditioner. On the inlet side of the air duct 2 is provided a switching damper 5 for controlling the ratio of the amount of air sucked from the inside air introduction port 3 to the amount of air sucked from the outside air introduction port 4 . The introduced air is sucked and conveyed into the air duct 2 by the blower 7 driven by the electric motor 6 . The air volume delivered by the blower 7 is regulated by the control motor 6 .

[0020] At a certain position downstream of the blower 7, an evaporator 8 is provided as a cooler, and at a certain position downstream of the evaporator 8, a hot water heater 9 is provided as a heater. Engine cooling water 10 supplied from an engine (not shown) circulates in a hot water heater 9 as a heat source of the heater, ...

Abstract

A control device includes a control object output target response calculation means for calculating and designating a target response in a transient state at which an output value of a control object reaches a target value, and a control object output estimation means for estimating an output value of the control object in the transient state for reaching the target value based on the target response designated by the control object output target response calculation means, and the estimation of the output value of the control object in the control object output estimation means is carried out by an equation including time as a variable. A simple and inexpensive control device, suitable for an air conditioning unit for vehicles, is provided, which can prevent an overshooting and an undershooting of a vehicle interior temperature and can improve the comfortableness by estimating the vehicle interior temperature in a transient state in an optimum manner.

Description

technical field [0001] The present invention relates to a control device, more particularly to a control device especially suitable for an automatic air conditioning system of a vehicle air conditioner, which can maintain equivalent or better performance than conventional automatic air conditioning while significantly simplifying the The components and the control system are improved, thus realizing a vehicle air conditioner with a lower cost. Background technique [0002] In a vehicle air conditioner having an evaporator (cooling device) and a heater (heating device), generally speaking, the air mix door and the control amounts of the cooling device and the heating device are controlled in accordance with the set temperature, and various feedback signals are considered to control the target blowing temperature so that the vehicle interior temperature becomes the target temperature. For example, in automatic air conditioning, thermal load detection values ​​such as vehicle ...
