Patent application number | Description | Published |
20090216404 | Driver Assistance System - A driver assistance system having a lane-keeping function, having a device for detecting the lanes on a roadway, and a control unit for intervening in the steering system of the vehicle for lane-keeping. Means are provided in the driver assistance system for detecting the position of the vehicle with respect to the lane marking of the lane. Furthermore, means are provided for detecting a travel of the vehicle through a curve. The control unit executes its control function as a function of the position of the vehicle on the lane and as a function of the cornering. The intervention depends on whether the vehicle is located on the inner side of the curve or on the outer side of the curve. | 08-27-2009 |
20110288709 | METHOD AND DEVICE FOR OPERATING A DRIVE TRAIN FOR A VEHICLE - A method and a device for operating a drive train for a vehicle is described, which has at least one drive unit, which is suitable for outputting a drive torque. The rates of change for triggering a torque increase and a torque reduction of the drive torque of the at least one drive unit are specified. This occurs in such a way that the specifiable rates of change of the torque increase and the torque reduction of the drive torque of the at least one drive unit are different. | 11-24-2011 |
20110301797 | METHOD AND DEVICE FOR OPERATING A HYBRID DRIVE FOR A VEHICLE - A method and a device for operating a hybrid vehicle, which ascertain the torque necessary for starting the non-operating internal combustion engine, and this torque is reserved by an additional drive unit. The torque necessary for starting the non-operating internal combustion engine is minimized by appropriately adjusting parameters of the internal combustion engine system. | 12-08-2011 |
20120022730 | METHOD FOR DRIVING A HYBRID VEHICLE IN A LOAD REVERSAL - A method for driving a hybrid vehicle during a load reversal includes: the application of a first torque on a first hybrid vehicle axle during an acceleration reversal; and the application of a second torque on a second hybrid vehicle axle during the acceleration reversal, a direction of action of the second torque being opposite to a direction of action of the first torque. | 01-26-2012 |
20120116623 | Method and device for operating a vehicle, in particular a hybrid vehicle - A method is described for operating a vehicle, in particular a hybrid vehicle, in which at least one of the axles of the vehicle is driven by a drive unit causing the vehicle to be accelerated at a predefined setpoint torque, in that a partial drive torque is transferred to at least one axle and the wheels coupled to it. For the setpoint torque requested by the driver to be converted into the corresponding acceleration of the vehicle, the partial drive torque of the steered axle and/or the unsteered axle is corrected while negotiating a curve in such a way that the vehicle is accelerated at the predefined setpoint torque. | 05-10-2012 |
20120130579 | METHOD AND DEVICE FOR DETERMINING THE BEGINNING OF A START PHASE OF AN INTERNAL COMBUSTION ENGINE IN A HYBRID VEHICLE - A method for determining the beginning of a start phase of an internal combustion engine in a hybrid vehicle, in which a second drive unit drives the hybrid vehicle, the internal combustion engine being started upon reaching a certain drive torque of the second drive unit. In order to always be able to achieve the maximum solely electric driving range of the hybrid vehicle using the second drive unit and simultaneously improve the driving comfort of the hybrid vehicle by optimizing the internal combustion engine start triggering, the internal combustion engine is started when a predicted drive torque of the second drive unit is less than or equal to the drive torque, as instantaneously measured and increased by a torque reserve, of the second drive unit. | 05-24-2012 |
20130116901 | METHOD AND DEVICE FOR ASCERTAINING A ROTATIONAL SPEED PARAMETER FOR DETERMINING A SETPOINT TORQUE - A method for ascertaining a rotational speed parameter for determining a setpoint torque for driving a drivetrain. The drivetrain comprises a first and at least one second drive assembly for driving a hybrid vehicle. The first drive assembly can be coupled to the drivetrain by means of a clutch. The second drive assembly is mechanically coupled to the drivetrain. When the hybrid vehicle is being driven by means of at least the first drive assembly, the rotational speed parameter corresponds to the value of a shaft rotational speed. When the hybrid vehicle is being driven only by means of the second drive assembly, the rotational speed parameter corresponds to the value of a determined rotational speed. | 05-09-2013 |
