Car air-conditioning system
First Claim
1. An automotive air conditioning system for use in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from said storage means, comprising:
- control means for controlling power generation of said power generation means and an operation of said air conditioning means, wherein said control means calculates a permissible power consumption increment in said air conditioning means by adding a permissible power generation increment to a permissible discharging current increment on the basis of the permissible power generation increment allowable in said power generation means and the permissible discharging current increment allowable in said storage means to increase power consumption of said air conditioning means within the range of the permissible power consumption increment and to increase power generation of said power generation means within the range of the permissible power consumption of the air conditioning means concerned.

Abstract
There is provided an automotive air conditioning system, which is free from troubles in traveling itself caused by power consumption in air conditioning means in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from the storage means. Control means calculates a permissible power consumption increment in the air conditioning means by adding a permissible power generation increment to a permissible discharging current increment on tha basis of the permissible power generation increment allowable in the power generation means and the permissible discharging current increment allowable in the storage means to increase power consumption of the air conditioning means within the range of the permissible power consumption increment and to increase power generation of the power generation means within the range of the permissible power generation increment according to an increment of power consumption of the air conditioning means.
