POWER SYSTEM FOR ON-BOARD DEVICES

WIPO Patent Application WO/2012/147721

A1

Provided is a power system for on-board devices, with which it is possible to change power sources smoothly while on-board devices are being operated, the power system for on-board devices (3) being applied to on-board devices (2) equipped with a first auxiliary output shaft (23) that obtains the power of the engine (11) from a drive shaft (12), a clutch (22) that connects and disconnects the drive shaft (12) and the first auxiliary output shaft (23), a pump (24) that is driven by the first auxiliary output shaft (23), and a hydraulic device (25) operated thereby. The power system (3) is provided with a clutch control unit (35), a motor (41) coupled to the first auxiliary output shaft (23), an engine speed detection unit (51), an engine control unit (34) that performs control on the basis of that detected value, a motor speed detection unit (52), a motor torque detection unit (53), a motor control unit (37) that performs control on the basis of the values detected by the detection units, a clutch control unit (35), and a basic instruction unit (31) that issues instructions to the engine control unit (34) and the motor control unit (36).
