Publication number: 20140094340Abstract: A controller of a vehicle control device, at the time of shifting from a motor drive mode to an engine drive mode by starting an engine in the motor drive mode, starts the engine by slipping an engine separating clutch and igniting the engine in a state where a lockup clutch of a fluid transmission device is slipped. The fluid transmission device is interposed between an electric motor and a drive wheel. The engine separating clutch selectively couples the engine to the electric motor.

Publication number: 20140083247Abstract: This manual transmission includes an input shaft, an output shaft, and an MG shaft. This transmission includes a motor speed change mechanism which establishes a power transmission system between the output shaft and the MG shaft and can selectively set the ratio of rotational speed of the MG shaft to that of the output shaft to one of two values (Hi or Lo).

The solenoid is operatively connected to the brake shoes via the mechanical biasing mechanism so that both brake shoes are operatively connected with the input member when the solenoid is energized. When the solenoid is deenergized, the first brake shoe remains operatively connected with and resists rotation of the input member when clockwise torque is applied to the input member and the second brake shoe remains operatively connected with and resists rotation of the input member when counterclockwise torque is applied to the input member.Type: ApplicationFiled: July 17, 2012Publication date: January 23, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Joel M.

Publication number: 20140007740Abstract: 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: ApplicationFiled: March 23, 2011Publication date: January 9, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Akinori Takahashi

Publication number: 20140005866Abstract: A hybrid vehicle and method of control are disclosed wherein the vehicle is propelled solely by the motor in some operating modes and the internal combustion engine is set to run whenever a brake pedal is released in other operating modes. In some operating modes, the engine is controlled to simulate a vehicle with a discrete ratio transmission, wherein the engine speed is controlled in response to vehicle speed and a virtual gear number. The virtual gear number changes in response to driver activation of shift selectors. When the driver selects a high gear number, a revised algorithm is utilized which allows some motor only operation but starts the engine in response to specified increases in accelerator pedal position.Type: ApplicationFiled: July 2, 2012Publication date: January 2, 2014Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ming Lang Kuang, Qing Wang, Jeffrey Randolph Holmes
