Patent number: 11958471Abstract: A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.Type: GrantFiled: June 22, 2021Date of Patent: April 16, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Koji Takaira, Akinori Takahashi, Yuuki Makino

Patent number: 8960034Abstract: In a vehicle drive device, a response to a range change request, during which the drive wheels are rotated in a low or high range, can be smoothly and quickly completed without using a synchronous engaging mechanism. When the range change is requested when the drive wheels are rotated in the low range or in the high range, the control devices disengage a clutch sleeve from a currently engaged gear piece so as to establish a neutral range, and control an output rotational speed of the motor generator such that a difference between an input rotational speed and an output rotational speed of the transmission mechanism is set to be zero, or be equal to or less than a predetermined value. After that, the control devices cause a connection processor to slide the clutch sleeve to be connected to a connection target gear piece.Type: GrantFiled: March 23, 2011Date of Patent: February 24, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventor: Akinori Takahashi
