Title:
DRIVE-SOURCE CONTROL DEVICE AND VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2009261193
Kind Code:
A
Abstract:

To excellently inhibit the generation of brake abnormal noise in a drive-source control device that makes an electric motor stop, when a vehicle is in a stopped state.

If a brake fluid pressure is low, a brake rotor is relatively rotated, while sliding with respect to a brake pad owing to a restoring force of a drive shaft or the like, when an electric motor 14 is stopped, thereby generating brake abnormal noise. Meanwhile, if the brake fluid pressure is large, it is possible to prevent the rotation of the brake rotor, when the electric motor 14 is stopped. Thus, if it is set such that the electric motor 14 is stopped, when the brake fluid pressure is larger than a set fluid pressure determined by an operating state of the electric motor 14, it is possible to properly inhibit the generation of brake abnormal noise.
