Control system for engine-driven auxiliary equipment for vehicles
First Claim
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).

Abstract
A control system (100) for an engine-driven auxiliary equipment (51) for vehicles including a central control circuit (31) for controlling the shifting of gear ratios (low, 2nd) of an automatic transmission (10), which drives a driven wheel with power from an engine (1), in conformity with a shift may (Mt) having as variables thereof the vehicle speed (V) of the vehicle and the output (Th) of the engine (1), depending on an instantaneous vehicle speed (Vd) and an instantaneous engine output (Thd), is to control the auxiliary equipment (51), which is driven with power from the engine (1) and provided with a mechanism (52, 53) for transmitting and interrupting the power from the engine (1) to the auxiliary equipment (51). The control system (100) further has a control map (Mc) intended for the auxiliary equipment (51), the control map (Mc) being overlapped on the shift map (Mt) and having as variables thereof the vehicle speed (V) of the vehicle and the output (Th) of the engine (1), and is to control the auxiliary equipment (591) in conformity with the control map (Mc).
