Title:
VEHICLE AND ITS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/123036
Kind Code:
A1
Abstract:
A hybrid vehicle (20) controls inverters (41, 42) as follows. When a shift lever
(81) is at N position and a brake including a brake actuator (92) is in a normal state,
the inverters (41, 42) are gate-shut out. When the shift lever (81) is at the N
position and the brake is in an abnormal state, the inverters (41, 42) are not gate-shut
out, so that a brake force obtained by a regenerative brake force by a motor (MG2)
and engine brake obtained by motoring an engine (22) by using a motor (MG1) are
outputted to a ring gear shaft (32a). Here switching between the output of the
regenerative brake force and the brake force by the engine (22) is performed depending
on whether a battery (50) cab be sufficiently charged. Thus, when the brake is
in an abnormal state, the brake force of the motors (MG1, MG2) is utilized.
