Patent number: 6671604Abstract: A method for variably setting the braking force in a hydraulic brake system of a motor vehicle with a brake pressure is produced which is applied to a wheel-braking device. In order to compensate a diminishing braking effect in hydraulic brake systems in wide ranges, the real actual friction factor between the brake disc and brake pad of at least one wheel brake is determined and compared with a prescribable desired friction factor, in the event of an impermissible undershooting of the actual friction factor by comparison with the desired friction factor, the brake pressure or a variable correlated with the brake pressure being increased to a value multiplied by a correction factor if the actual friction factor is within a defined friction factor stabilization range which comprises a plurality of friction factors below the desired friction factor.Type: GrantFiled: December 31, 2001Date of Patent: December 30, 2003Assignee: DaimlerChrysler AGInventors: Georg Frentz, Hans-Georg Riedel

Method for manually stipulating the transmission ratio of a continuously variable transmission (CVT)
Patent number: 6671602Abstract: The invention relates to a method for manually stipulating the transmission ratio of a continuously variable transmission (CVT) for a motor vehicle. The CVT comprises a control device, a shifting or selecting device, a starting element and a variator for adjusting the transmission ratio which is driven, in particular, by an internal combustion engine. The control device processes input signals derived from a driver-vehicle system within the framework of an operational strategy for stipulating the transmission ratio, the rotational speed of the drive motor or a variator input rotational speed. In a first automatic operation mode, the operational strategy automatically selects the transmission multiplication. In a second manual operational mode, the driver can directly intervene, via the shifting or selecting device, in the selection of the transmission multiplication.Type: GrantFiled: February 20, 2002Date of Patent: December 30, 2003Assignee: ZF Batavia L.L.C.Inventors: Patrick Speicher, Ralf Vorndran, Anton Welte -
Patent number: 6665594Abstract: The present application discloses plug and play modular mission payloads in the context of aerial vehicles, and a supporting open system architecture that moves the control function of mission payloads away from the ground station and into the aerial vehicle.

Patent number: 6636802Abstract: A terminal device for reading a cartographic file in which updating one cartographic file does not require updating cartographic files in the neighboring units. For this purpose, cartographic files which represent respective units extracted by dividing a map into a plurality of areas each comprise node records generated for respective nodes and link records generated for respective links. Given node records contain coordinate information about neighboring nodes which define connections of roads between its unit and a neighboring unit. The cartographic files are stored in a first storage device. The data processing portion executes a process of searching for a route by using the cartographic files. During the route search, the data processing portion traces the connection from a road in one unit to a road in another, neighboring, unit on the basis of the coordinate information about the neighboring nodes of said one unit and said neighboring another unit.Type: GrantFiled: May 23, 2001Date of Patent: October 21, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuyuki Nakano, Yasuhiro Ihara, Yoshiki Ueyama, Akihiro Suzuki, Hisaya Fukuda

Patent number: 6636805Abstract: A remote navigation device and navigation system which can reduce communications costs by minimizing route guidance data transmitted to an in-vehicle navigation device is configured so that it can obtain guide area information specifying areas where guidance is not needed. When generating route guidance data to be transmitted to an in-vehicle navigation device, the remote navigation device removes the routes which pass through areas where route guidance is not needed, and generates route guidance data for just the other routes. By transmitting only such route guidance data to the in-vehicle navigation device, the amount of transmitted data can be reduced.Type: GrantFiled: November 3, 2000Date of Patent: October 21, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Akihito Tada, Hironobu Sugimoto, Masayuki Yurimoto

Patent number: 6600991Abstract: Method and system for determining an optimal route for an aircraft moving between first and second waypoints in a general wind environment. A selected first wind environment is analyzed for which a nominal solution can be determined. A second wind environment is then incorporated; and a neighboring optimal control (NOC) analysis is performed to estimate an optimal route for the second wind environment. In particular examples with flight distances of 2500 and 6000 nautical miles in the presence of constant or piecewise linearly varying winds, the difference in flight time between a nominal solution and an optimal solution is 3.4 to 5 percent. Constant or variable winds and aircraft speeds can be used. Updated second wind environment information can be provided and used to obtain an updated optimal route.Type: GrantFiled: August 14, 2001Date of Patent: July 29, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Matthew R.

Patent number: 6594559Abstract: In an iterative method of determining aircraft flight data parameters using first and second multi-function probes, an assumed value of a first aircraft parameter is defined to be equal to an initial value. Using the assumed value of the first aircraft parameter together with the respective local angles of attack determined at first and second multi-function probes, first and second estimates of a second aircraft parameter are calculated and compared. If the first and second estimates of the second aircraft parameter are within tolerance of each other, then the first aircraft parameter is approximately equal to the assumed value, and the second aircraft parameter is determined from the first and second estimates. If the first and second estimates of the second aircraft parameter are not within tolerance of each other, then an iterative process is continued to correctly determine the first and second parameters.Type: GrantFiled: May 8, 2001Date of Patent: July 15, 2003Assignee: Rosemount Aerospace Inc.Inventors: Steve F.
