Document Type and Number:
WIPO Patent Application WO/2009/036606
Kind Code:
A1
Abstract:
An economic operation method of an engine having servo control system is provided.
The servo control system includes servo devices of two permanent magnet motors,
a main control unit (13), an engine control unit (16) and an energy storage unit
(15). The method includes the steps as follow: 1) the servo control system acquires
current driving requirement power and charging requirement power to obtain
total requirement power; 2) the main control unit (13) controls one of first and
second motors or both of them to operate as a power generator when total requirement
power is between lower limit value and upper limit value of economic operation
range; 3) the servo control system controls the engine to operate at upper limit
value of economic operation range when total requirement power is greater than
upper limit value of economic operation range; 4) the servo control system switches
off the engine and drives the hybrid vehicle by the electromotor only when total
requirement power is less than lower limit value of economic operation range.
