Control device of air conditioner for automotive vehicle

Claim 2

A control device of an air conditioner for an automotive vehicle, the air conditioner having a compressor for making a refrigerating cycle, the automotive vehicle having an internal combustion engine with an automatic transmission, said control device comprising: means for stopping the compressor when a transmission controller outputs a signal indicative of an acceleration of the automotive vehicle; and means for starting the compressor when a first predetermined time has elapsed from the stopping of the compressor and a second predetermined time has elapsed from a time when the transmission controller outputs a signal indicative of a judgment of the shifting of the automatic transmission.

Claim 3

A control device as claimed in claim 1, wherein the automotive vehicle is provided with an automatic transmission connected with an internal combustion engine, the automatic transmission being controlled by a transmission controller.

Claim 4

A control device as claimed in claim 2, wherein said compressor stopping means stops the operation of the compressor when said compressor stopping means receives signals indicative of the accelerating condition of the automotive vehicle from the transmission controller.

Claim 5

A control device as claimed in claim 1, further comprising a first judging means for judging that a stopping time period of the compressor is larger than a first predetermined time and a second judging mean for judging that a second predetermined time elapsed from a shifting judgment of the automatic transmission, said first judging means and said second judging means output the signals to said compressor starting means.

Claim 8

An air conditioner system for an automotive vehicle, said air conditioner providing cool air into a passenger compartment of the automotive vehicle by means of its refrigeration cycle, said automotive vehicle comprising an internal combustion engine with an automatic transmission, said air conditioner system comprising: a compressor rotatingly connected with the internal combustion engine; a transmission controller outputting a signal indicative of an accelerating condition of the automotive vehicle; an air conditioner switch by which a passenger of the automotive vehicle switches on the air conditioner system, said air conditioner switch outputting a signal indicative of a turned-on state of the air conditioner system; and an air conditioner controller receiving signals from said transmission controller and said air conditioner switch, said air conditioner controller stopping said compressor when the automotive vehicle is in an accelerating condition, said air conditioner controller starting said compressor when said air conditioner switch is turned on, when a turned-off time period of said compressor is larger than a first predetermined time, and when an elapsed time from when the transmission controller outputs a signal indicative of a judgment of the shifting of the automatic transmission is larger than a second predetermined time.

Claim 9

An air conditioner system for an automotive vehicle, said air conditioner providing cool air into a passenger compartment of the automotive vehicle by means of its refrigeration cycle, said automotive vehicle comprising an internal combustion engine with an automatic transmission, said air conditioner system comprising: a compressor rotatingly connected with the internal combustion engine; a transmission controller outputting a signal indicative of an accelerating condition of the automotive vehicle; an air conditioner switch by which a passenger of the automotive vehicle switches on the air conditioner system, said air conditioner switch outputting a signal indicative of a turned-on state of the air conditioner system; and an air conditioner controller receiving signals from said transmission controller and said air conditioner switch, said air conditioner controller stopping said compressor when the automotive vehicle is in an accelerating condition, said air conditioner controller starting said compressor when said air conditioner switch is turned on, when a turned-off time period of said compressor is larger than a first predetermined time, and when an elapsed time from when the transmission controller outputs a signal indicative of a judgment of the shifting of the automatic transmission is larger than a second predetermined time.

Claim 10

An air conditioner system as claimed in claim 6, wherein the accelerating condition of the automotive vehicle is judged from the shifting of the automatic transmission and an opening degree of an engine throttle.

Claim 11

An air conditioner controller for an automotive vehicle including an internal combustion engine with an automatic transmission, said air conditioner controller controlling operation of an air conditioner, the automatic transmission being controlled by a transmission controller, said air conditioner system comprising: a stopping means for stopping the operation of a compressor of the air conditioner; a first timer means for counting a first predetermined time when the transmission controller outputs a signal indicative of an acceleration of the automotive vehicle; a second timer means for counting a second predetermined time when the transmission controller outputs a signal indicative of a judgment of the shifting of the automatic transmission; and a starting means for starting the compressor when the first predetermined time and second predetermined time have both elapsed.

Claim 12

An air conditioner controller for an automotive vehicle including an internal combustion engine with an automatic transmission, said air conditioner controller controlling operation of an air conditioner, the automatic transmission being controlled by a transmission controller, said air conditioner system comprising: a stopping means for stopping the operation of a compressor of the air conditioner; a first timer means for counting a first predetermined time when the transmission controller outputs a signal indicative of an acceleration of the automotive vehicle; a second timer means for counting a second predetermined time when the transmission controller outputs a signal indicative of a judgment of the shifting of the automatic transmission; and a starting means for starting the compressor when the first predetermined time and second predetermined time have both elapsed.
