Publication number: 20240159556Abstract: A method for providing a navigation map to a vehicle includes receiving, at a server, a request message in order to update the navigation map of the vehicle. The method further includes ascertaining a change to a portion of the navigation map of the vehicle on the basis of the received request message from the vehicle and on the basis of a current portion of the navigation map of the server outside the vehicle. In addition, the method includes determining a scope of change for the portion of the navigation map of the vehicle on the basis of the ascertained change, and checking whether the determined scope of change for the portion of the navigation map of the vehicle equals, exceeds, or falls below a predefined threshold value. A response message for updating the navigation map of the vehicle is generated based on the determined scope of change.Type: ApplicationFiled: January 21, 2022Publication date: May 16, 2024Inventors: Ulrich Muehlbauer, Christian Denich, Sabrina Denich

Patent number: 8131454Abstract: A method is described for starting an internal combustion engine having an E-machine coupled to it in a motor vehicle, after the input of a certain torque command at a drive control of the internal combustion engine, the internal combustion engine being accelerated for the start by the E-machine, and the internal combustion engine being set by the drive control, via actuators, to specified characteristics values for the start. To reduce exhaust gas emissions at the start of the internal combustion engine, the internal combustion engine is accelerated by the E-machine, without the injection of fuel, until the engine torque that is able to be implemented by the internal combustion engine, essentially corresponds to the torque command, and the injection of fuel into the internal combustion engine is only then released.Type: GrantFiled: July 30, 2008Date of Patent: March 6, 2012Assignee: Robert Bosch GmbHInventors: Frank Steuernagel, Jens-Werner Falkenstein, Markus Vogelgesang, Martin Lang, Karsten Kroepke, Christian Muehlbauer

Patent number: 7630817Abstract: A method for controlling the speed of a vehicle, the method making it possible to maintain a predefined setpoint speed even on downhill grades. In the event that the actual speed of the vehicle exceeds the predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle will be activated.Type: GrantFiled: February 3, 2003Date of Patent: December 8, 2009Assignee: Robert Bosch GmbHInventors: Erwin Lock, Christian Muehlbauer, Mario Kustosch

Patent number: 7593801Abstract: In a method for controlling a speed of a vehicle, when an actual speed of the vehicle exceeds a predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle is activated. In the method, the first predefined speed difference has a value greater than zero. Also, when the actual speed exceeds the setpoint speed by a second predefined speed difference, which is smaller than the first predefined speed difference, an idle speed control can be activated and a torque request of activated ancillary components can be reduced. Further, when the actual speed exceeds the setpoint speed by a sixth predefined speed difference, which is smaller than the first predefined speed difference, an ancillary component can be activated.Type: GrantFiled: January 11, 2008Date of Patent: September 22, 2009Assignee: Robert Bosch GmbHInventors: Erwin Lock, Christian Muehlbauer, Mario Kustosch

Patent number: 7548812Abstract: A method and a device for controlling the speed of a vehicle are described. In the transition from a dynamic to a steady-state operating state, the initially accepted setpoint value is corrected using a correcting value which depends on the system deviation prevailing at the time when the longitudinal acceleration of the vehicle has reached, exceeded, or fallen below a predetermined threshold value.Type: GrantFiled: September 6, 2002Date of Patent: June 16, 2009Assignee: Robert Bosch GmbHInventors: Jens Guenthner, Hans Schulte, Boris Knobloch, Mario Kustosch, Christian Muehlbauer

Patent number: 7493981Abstract: A method and an arrangement for the speed control of a vehicle as well an operator-controlled element are disclosed which make possible an improved acceleration and/or deceleration input by the driver of the motor vehicle. The speed control takes place in dependence upon a value for an acceleration and/or deceleration of the motor vehicle with this value being pregiven with the aid of an operator-controlled element. The function of the operator-controlled element is different from the function of an accelerator pedal and a brake pedal. With the actuation of the operator-controlled element, one of several different values for the acceleration and/or deceleration is selected and pregiven.Type: GrantFiled: May 5, 2003Date of Patent: February 24, 2009Assignee: Robert Bosch GmbHInventors: Mario Kustosch, Christian Muehlbauer, Michael Glora

Patent number: 7194352Abstract: A method and an arrangement for controlling the speed of a vehicle make possible a comfortable adaptation of an incrementation or decrementation of a pregiven desired speed. The desired speed is changed by the actuation of an operator-controlled element (1). The extent of the change of the desired speed is adjusted in dependence upon at least one piece of data as to the instantaneous driving situation of the vehicle.Type: GrantFiled: October 2, 2003Date of Patent: March 20, 2007Assignee: Robert Bosch GmbHInventors: Christian Muehlbauer, Erwin Lock

Patent number: 7191041Abstract: A method is for making a diagnosis as to signal plausibility in a speed sensor of a motor vehicle. In the method, the speed sensor outputs a pulse sequence to an evaluation circuit in dependence upon the speed of the vehicle and, in a steady-state operating condition of the motor vehicle, a ratio is formed between the determined speed and an engine rpm and the ratio is averaged over a pregiven time. A plausibility is determined only when the formed mean value lies in a value range permissible for the steady-state operating condition.Type: GrantFiled: February 4, 2004Date of Patent: March 13, 2007Assignee: Robert Bosch GmbHInventors: Gerit von Schwertfuehrer, Christian Muehlbauer

Patent number: 7059999Abstract: A method and an arrangement for controlling the drive unit of a vehicle are suggested which prevent a lost motion and a dead path in the interpretation of the position of the accelerator pedal for forming a desired acceleration. An acceleration command is derived from a position of an operator-controlled element (1), especially of an accelerator pedal, and a desired value for an output quantity of the drive unit is formed in dependence upon the acceleration command. A minimum value and/or a maximum value for the acceleration of the vehicle is determined in dependence upon an instantaneous running resistance. The minimum value and/or the maximum value are assigned to respective boundaries of an adjustment range for the position of the operator-controlled element (1).Type: GrantFiled: February 3, 2003Date of Patent: June 13, 2006Assignee: Robert Bosch GmbHInventors: Michael Glora, Christian Muehlbauer, Mario Kustosch

Patent number: 6901325Abstract: A method and an arrangement are suggested for limiting the speed of a vehicle to a limit speed with the arrangement not needing an integral component and nonetheless being precise at steady state. A maximum permissible acceleration proportional to the difference between an actual speed and the limit speed is determined. From the maximum permissible acceleration, a limit value for an output quantity of a drive unit of the vehicle is determined by means of a vehicular dynamic operation equation in dependence upon the running resistance. The magnitude of the limit value for limiting the speed of the vehicle to the limit speed may not be exceeded.Type: GrantFiled: September 5, 2003Date of Patent: May 31, 2005Assignee: Robert Bosch GmbHInventors: Mario Kustosch, Christian Muehlbauer, Michael Glora
