AUXILIARY DRIVE CONTROLLER FOR VEHICLE

摘要

PURPOSE:To maintain the auxiliary function with high precision even in case of a device which requires the fine load control on an auxiliary side, by controlling a controller for transmission which sets the speed change ratio between an engine and the auxiliary by a controller for auxiliary which sets at least the revolution speed of the engine auxiliary. CONSTITUTION:A refrigerator 2 as auxiliary is connected with the output shaft side of an engine 1 for traveling through a CVT (mechanical type continuously variable transmission) 3, and the inside of a refrigeration chamber 4 is cooled by coolant. In this case, the necessary revolution speed is calculated by a refrigerator controller 7 on the basis of the temperature difference between the actual temperature detected by a temperature sensor 5 installed in the refrigeration chamber 4 and the aimed temperature 6 set on a driver's seat side. The hydraulic control signal corresponding to the speed change ratio is calculated by a CVT controller 8 on the basis of the actual speed detected by a revolution sensor 9 installed on the engine 1 for traveling. Accordingly, the hydraulic force applied to the CVT 3 side through a hydraulic power source 10 can be adjusted in real time.
