1. A control system (100) for controlling engine-driven auxiliary equipment (51)for a vehicle comprising;

  • an engine (1);

    an automatic transmission (10) receiving power from said engine (1) to drive a driven wheel;

    said automatic transmission (10) having a plurality of gear ratios ("first", "second");

    said auxiliary equipment (51) being driven with power from said engine (1); and

    said auxiliary equipment (51) having transmitting-and-interrupting means (52,

         53) for transmitting and interrupting the power from said engine (1) to said auxiliary equipment (51),a central control circuit (31);

    vehicle speed detecting means (32) for feeding said control circuit with a signal (Sv) representing an instantaneous vehicle speed (Vd);

    engine output detecting means (33) for feeding said control circuit (31) with a signal (Sth) representing an instantaneous engine output (Thd);

    a shift map (Mt) for said automatic transmission (10);

    said shift map (Mt) having as variables thereof the speed (V) of said vehicle and the output (Th) of said engine (1); and

    said control circuit (31) for controlling the shifting of said gear ratios depending on said shift map (Mt),whereinsaid control system further comprisesa control map (Mc) for controlling said auxiliary equipment (51);

    said control may (Mc) being overlapped on said shift map (Mt); and

    said control map (Mc) having as variables thereof the speed (V) of said vehicle and the output (Th) of said engine (1); and

    said transmitting-and-interrupting means (52,

         53) of said auxiliary equipment (51) is controlled depending on said control map (Mc).
