SPEED CHANGE CONTROLLER OF HYBRID TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To prevent driving torque and speed-change speed from changing with a sense of incongruity when correcting target motor/generator torque out of an operable region to a value within the region.

SOLUTION: When a combination of the target motor/generator torque T*10, T*20is out of the operable region FX like an occasion of the combination being the value corresponding to an operating point before correction "a white circle," regarding "a black circle," a point which is on a straight line connecting the operating point before correction "the white circle" and an original point O within the operable region FX and the nearest to the operating point before correction "the white circle," as an operating point after correction, the motor/generator torque T1, T2in the operating point after correction "the black circle" are regarded as motor/generator torque command values T*1, T*2. When the target motor/generator torque T*10, T*20are corrected to the values within the operable region FX to be the motor/generator torque command values T*1, T*2, as the driving torque is not changed even with the correction of the target motor/generator torque T*10, T*20, durability of a motor/generator and the life of a battery can be improved while preventing unnatural acceleration and deceleration of a vehicle from being generated.
