Patent number: 9255639Abstract: In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.Type: GrantFiled: June 24, 2008Date of Patent: February 9, 2016Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Heinrich Dueckinghaus, Manfred Gersmann

Publication number: 20150027798Abstract: A vehicle control apparatus according to the present invention includes a PHEV-ECU containing a measuring unit which measures the amount of torsional stress on the front drive shafts in a parking lock state and a control unit which controls the torque of the front motor. When the parking lock state is released, the torque acting as a load on the rotation of the first motor upon the release of the torsional stress on the drive shaft, is determined based on the torsional stress measured. Further, the front motor is controlled to output the determined torque.Type: ApplicationFiled: April 17, 2014Publication date: January 29, 2015Applicant: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventor: Takeo NAGAMORI
