First Claim
Patent Images
1. A combined power system, comprising:
- an active power source arranged to supply power to a load;
an auxiliary power source;
a transmission including means for transmitting power from said active power source and said auxiliary power source to said load;
a rotational speed and torque detector including means for detecting (i) a rotational speed of a power input from the active power source to the transmission, and (ii) a torque difference between a rotational torque of said power input and a rotational torque of an output of said transmission to said load; and
a controller including means for controlling said auxiliary power source in response to detection by said detector of said rotational speed and said torque difference.

Abstract
A combined power system includes an active power source and an auxiliary power source. The rotation speed signal of the active power source and the rotation torque difference between the active power source and an output shaft of the combined power system is used as a basis for controlling the auxiliary power source to provide proportional auxiliary speed driving, or proportional auxiliary torque driving, or reverse damping from regenerative braking.
