Problems solved by technology

On the other hand, even when the air conditioning is not fully effective, the upper limit of the rotation speed of the electric compressor is determined by the vehicle speed, so there is a problem that cooling cannot be performed according to the user's request

Embodiment 1

[0029] figure 1 and figure 2 Example 1 of the present invention is shown.

[0030] exist figure 1 , reference numeral 1 denotes an air conditioner (HVAC unit) mounted on a vehicle including an electric motor, such as an electric vehicle (EV) and a hybrid vehicle (HEV). The air conditioner 1 includes a passage forming member 3 for forming an air flow passage 2 .

[0031] A base 6A of the inside / outside air switching damper 6 , a base 9A of the outlet switching damper 9 , and a base 11A of the opening / closing damper 11 are provided on the passage forming member 3 . The inside / outside air switching damper 6 swings inward at one end as the upstream side to switch between the outside air inlet 4A connected to the outside air inlet pipe 4 and the inside air inlet 5A connected to the inside air inlet pipe 5 . The outlet switching damper 9 swings inward at the other end as the downstream side to switch between the defrosting outlet 7A connected to the defrosting duct 7 and the ...

Embodiment 2

[0067] Figure 3 to Figure 6 is a view showing Embodiment 2 according to the present invention.

[0068] In the following embodiments, the same functions as in Embodiment 1 are described using the same reference numerals.

[0069] Embodiment 2 is characterized by the following points. The upper limit of the rotation speed of the electric compressor 22 is not determined by a two-dimensional matrix of the vehicle speed (for example, five levels of vehicle speed) and the user's air conditioning request, but by an electric motor determined by the vehicle speed (for example, five levels of vehicle speed). The upper limit value (temporary) of the rotation speed of the compressor 22 and the constant of the rotation speed of the electric compressor 22 found through collective adaptation or the like according to the user's air conditioning request are determined. Specifically, the air conditioning control unit 27 adds each constant (A1 to A5) of the rotation speed of the electric com...

Embodiment 3

[0079] Figure 7 to Figure 10 is a view showing Embodiment 3 according to the present invention.

[0080] Embodiment 3 is characterized by the following points. That is to say, the upper limit value of the rotational speed of the electric compressor 22 is not determined by a two-dimensional matrix of the vehicle speed (for example, five levels of the vehicle speed) and the user's air conditioning request, but as Figure 7 As shown in , the upper limit value (temporary) of the rotation speed of the electric compressor 22 determined by the vehicle speed (for example, five levels of the vehicle speed) and the coefficient of the rotation speed of the electric compressor 22 found by uniform adaptation or the like according to the user's air conditioning request definite. Specifically, the air-conditioning control unit 27 multiplies each coefficient (B1 to B5) of the rotational speed of the electric compressor 22 by each rotational speed upper limit value (temporary) (N1 to N5) of...

Abstract

The invention provides an automotive air conditioning device. A control means (27) involves a fan blowing air amount setting means (27B) which is connected to an air-blowing fan (12) that can supply air that has been cooled by an electrical compressor (22) to the inside of an automobile and can set the amount of air to be blown by means of the air-blowing fan (12). The control means (27) can set the upper limit of the number of rotations of the electric compressor (22) based on the vehicle speed which has been detected by a vehicle speed detection means (37) and the amount of air to be blown which has been set by the fan blowing air amount setting means (27B).

Description

technical field [0001] The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle for controlling an electric compressor of an air conditioner mounted on a vehicle such as an electric vehicle and a hybrid vehicle. Background technique [0002] In recent years, environment-conscious vehicles such as electric vehicles (EV) and hybrid vehicles (HEV) have drawn attention. An electric motor driving the vehicle and an air conditioner including an electric compressor are mounted on such an environment-conscious vehicle. [0003] Vehicles such as electric vehicles and hybrid vehicles can be driven without any noise due to the driving of electric motors, etc., and therefore, there are cases where the operating noise of the electric compressor makes passengers feel uncomfortable in a range where the vehicle speed is low and when the vehicle is stopped. [0004] prior art literature [0005] patent documents [00...
