Patent number: 8721500Abstract: A method for controlling deceleration of a motor vehicle having an internal combustion engine with an automated clutch, in which method, when a deceleration is present, a deceleration fuel cutoff is carried out in order to generate a drag torque as a drive torque if the engine speed is higher than a deceleration fuel cutoff threshold wherein when a braking request is present, the effect of the engine speed is evaluated, a comparison is carried out between the expected engine speed or the current engine speed and the deceleration fuel cutoff threshold, and the internal combustion engine is adjusted to a deceleration mode or a deceleration fuel mode is maintained only if the expected or current engine speed is higher than the deceleration fuel cutoff threshold.Type: GrantFiled: December 20, 2011Date of Patent: May 13, 2014Assignee: Dr. Ing. H.C. F. Porsche AktiengesellschaftInventors: Klaus Bastian, Martin Roth

Patent number: 8590648Abstract: A hybrid drive train for a vehicle has an internal combustion engine, first and second electric machines and a transmission that are mechanically connected to one another to drive at least one axle of the vehicle. The internal combustion engine (1) and the first electric machine (2) are provided on an input shaft of the transmission (3), and the second electric machine (4) is provided on an output shaft (6) of the transmission or on an axle of the vehicle. The maximum power and/or the maximum torque of the internal combustion engine are/is substantially larger than the power or torque that can be transmitted by the transmission.Type: GrantFiled: October 18, 2010Date of Patent: November 26, 2013Assignee: Dr. Ing. h.c.

Patent number: 8560186Abstract: A method for identifying a driving resistance of a motor vehicle includes the steps of recording values of control and/or state variables of the vehicle during a driving state of the vehicle when a control route is covered, adapting parameters of a vehicle model and/or a model of the area surrounding the vehicle on the basis of the values of the recorded control and state variables, identifying the driving resistance on the basis of the adapted vehicle model and/or the surrounding area model, wherein the parameters of the vehicle model and/or the surrounding area model are adapted on the basis of a distinction between driving states, wherein these driving states include a driving state of a closed drive train with a positive driver demand torque, a driving state of a closed drive train without a positive driver demand torque, and/or and a driving state with an open drive train.Type: GrantFiled: April 5, 2011Date of Patent: October 15, 2013Assignee: Dr. Ing. h.c.F.

Publication number: 20080065304Abstract: A motor vehicle, in particular a passenger motor vehicle, has a drive train which has a drive assembly, at least one gear mechanism and a plurality of drive axles. The drive train has at least one transverse lock for locking a rotational speed equalization between wheels of one drive axle and at least one longitudinal lock for locking a rotational speed equalization between two drive axles. A torque distribution of the drive train, namely a torque distribution between the drive axles of the drive train and/or a torque distribution between the wheels of the drive axles, can be determined and visualized for a driver.Type: ApplicationFiled: July 9, 2007Publication date: March 13, 2008Inventors: Klaus Bastian, Adam Kobielski, Dominik Bender, Alexander Bogner, Markus Hofbauer, Markus Gantikow

Patent number: 6996466Abstract: A method of controlling the handling of vehicles having a controllable longitudinal clutch and/or a controllable main-axle lateral lock in the case of all-wheel systems and a controllable lateral lock in the case of vehicles with a single-axle drive. The input quantities are first detected and processed, and subsequently, a comparison takes place of the desired driving direction, which is defined by way of the steering angle (LW), and the actual moving direction (BR) of the vehicle. If the two values deviate from one another by a definable reference value (RW), the coupling between the front axle and the rear axle of the vehicle is increased for increasing the yaw damping, or, when a controllable main-axle lateral lock is present, the locking torque of the lateral lock is increased, or the two measures are initiated simultaneously.Type: GrantFiled: September 26, 2003Date of Patent: February 7, 2006Assignee: Dr. Ing. h.c.F.

Patent number: 6917869Abstract: Method of controlling the vehicle handling of vehicles having a controllable longitudinal clutch and/or a controllable main-axle lateral lock in the case of all-wheel systems and a controllable lateral lock in the case of vehicles with a single-axle operation wherein at least the driving speed (v), the lateral acceleration (aq) and the actual steering angle (LW(act)) are detected. From the filed characteristic diagram, which extends along the driving speed (v) and the lateral acceleration (aq), the pertaining steering angle (LW(KF)) is determined for the respective driving speed (v) and the lateral acceleration (aq) and is then compared with the actual steering angle (LW(act)). If the two steering angles deviate from one another by at least a definable amount, the lateral acceleration is adapted by changing the locking torque for a stable vehicle handling.Type: GrantFiled: September 26, 2003Date of Patent: July 12, 2005Assignee: Dr. Ing. h.c.F.
