Title:
VEHICULAR DRIVING CONTROLLER
Document Type and Number:
Japanese Patent JP2009220665
Kind Code:
A
Abstract:

To prevent excessive reduction of output torque of a motor even when performing processing for regenerative power by making actual generation power follow target generation power.

A vehicular driving force controller has: a map retrieval part 301 for calculating target power for driving the motor 4; a power consumption calculation part 307 for acquiring actual power in the motor 4; a second subtractor 303 for calculating a deviation between the target driving power and the actual power; and a power compensation PI control part 308 and a first upper/lower limit limiter part 305 calculating a q axis current instruction value Iq* for driving the motor 4 such that the deviation becomes zero, and restricting a lower limit side of the q axis current instruction value Iq* based on a motor torque instruction value.
