CONTROLLER FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a controller of a vehicle for maintaining a minimum fuel consumption rate (miximum efficiency) even when efficiency property of an engine significantly changes according to environment conditions or control conditions, and for achieving the minimum fuel consumption rate by performing stable feedback search of an operating point with a small memory size without interference.

SOLUTION: In the vehicle equipped with an engine 1, a power generation motor 2 and a power generation system for controlling engine torque Te and generator RPM Ng, a power generation control means (fig.2) is provided with: a basic operating point setting part 21; ab RPM axial direction best fuel efficiency search part 23 for feedback-correcting a target generator RPM Ng* to minimize a fuel consumption rate ε; a torque axial direction best fuel efficiency search part 24 for feedback-correcting target engine torque Te* to minimize the fuel consumption rate ε; a timing control part 25 for causing the RPM axial direction best fuel efficiency search part and the torque axial direction best fuel efficiency search part to alternately function; a generator RPM control part 26; and an engine torque control part 27.
