POWER ASSISTING METHOD AND EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a power assisting method by a driving force of a motor depending on the value of input torque in order to reduce the burden on opera tor when the load is big and in order to improve the operability. SOLUTION: A power assisting torque is generated as an output according to the value to which the integral of the exceeded part is added when input torque exceeds the first specified value t1. The power assisting torque is generated as an output according to the input torque and no more addition of integral value when the input torque decreases blow the second specified value t2. Thus the power assisting torque increases as the passage of time when the input torque is bigger than the first specified value and it becomes easy for an operator to handle over in a heavy load without a burden.
