Patent number: 9995235Abstract: A method for plausibilization of an engine control function for an internal combustion engine includes: provision of injection parameters with which an injection of fuel into cylinders of the internal combustion engine is controlled on the basis of a torque that is to be realized; estimation of an actual torque of the internal combustion engine as a function of the injection parameters; and evaluation of the actual torque as a function of the torque that is to be realized, in order to plausibilize the engine control function.Type: GrantFiled: December 5, 2008Date of Patent: June 12, 2018Assignee: ROBERT BOSCH GMBHInventors: Guenter Kettenacker, Volker Pitzal

Patent number: 8838306Abstract: In a method and a device for operating a drive unit, a first output variable of the drive unit is restricted; a setpoint value of a second output variable of the drive unit is specified; and an actual value of the second output variable of the drive unit is determined. The setpoint value is compared with the actual value, and if it is determined that the actual value does not exceed the setpoint value, then the first output variable is restricted to a first value. If it is determined that the actual value exceeds the setpoint value, then the first output variable is restricted to a second value smaller than the first value.Type: GrantFiled: July 21, 2008Date of Patent: September 16, 2014Assignee: Robert Bosch GmbHInventors: Guenter Kettenacker, Christian Ruland, Klaus Schwarze

Patent number: 8423248Abstract: In a method for checking the operation of specifying an output variable of a drive unit, when a setpoint value of the output variable is specified, a check is performed as to whether this specification of the setpoint is caused by an operation of the control element. If it is determined that this is not the case, then an error is detected.Type: GrantFiled: July 29, 2008Date of Patent: April 16, 2013Assignee: Robert Bosch GmbHInventors: Guenter Kettenacker, Christian Ruland, Maria-Dolores Sanchez Moreno

Patent number: 8160798Abstract: A method and a device are described for regulating the velocity of a vehicle, which include a hysteresis function and prevent an unwanted activation and deactivation of the engine brake. For this purpose, a setpoint velocity (V-setpoint) of the vehicle is predefined. An actual velocity (V-actual) of the vehicle is detected and, as a function of the difference between the actual velocity (V-actual) and the setpoint velocity (V-setpoint), an output quantity (Msetpoint) of a drive unit of the vehicle is predefined in such a way that the actual velocity (V-actual) is approximated to the setpoint velocity (V-setpoint). A first lower limiting value (uG1) for limiting the output quantity (Msetpoint) toward the lower end is predefined as long as the actual velocity (V-actual) exceeds the setpoint velocity (V-setpoint) by less than a first predefined threshold value (offs1).Type: GrantFiled: July 22, 2008Date of Patent: April 17, 2012Assignee: Robert Bosch GmbHInventor: Guenter Kettenacker

Publication number: 20110153145Abstract: A method is described for detecting errors in a control unit for controlling and/or regulating an engine in a vehicle, in which the presence of a faulty state of the engine and/or the vehicle is detected, a difference between at least one instantaneous value of an operating variable and a limiting value provided for this operating variable being formed multiple times, the formed differences being added to a sum, and the faulty state being evaluated as an error if the sum exceeds a predefinable threshold value.Type: ApplicationFiled: December 10, 2010Publication date: June 23, 2011Inventor: Guenter KETTENACKER

Patent number: 7909734Abstract: Vehicle operation is controllable and/or regulatable by specifying a driver request describing a setpoint rotational speed or a setpoint torque via an accelerator pedal, detecting the instantaneous position of the accelerator pedal and controlling and/or regulating the internal combustion engine such that the setpoint rotational speed or setpoint torque is achievable. To provide for a sustained-action brake to be easily operated in the vehicle, and increase the vehicle's range of use, one of possible braking actions of the vehicle is specified by selecting a determined position of the pedal. As a function of an instantaneously detected position of the accelerator pedal, the operation of the vehicle is controlled and/or regulated such that braking power specified via the accelerator pedal is achieved. A variation in the braking power specified via the accelerator pedal is also converted as continuously as possible to a corresponding braking power by suitably activating additional components or devices.Type: GrantFiled: December 14, 2007Date of Patent: March 22, 2011Assignee: Robert Bosch GmbHInventor: Guenter Kettenacker

Patent number: 7225059Abstract: In a method for operating a vehicle having a drive, a value of an internal torque to be supplied by the drive is determined from a positive propulsion torque requested by a user or a control and/or regulating system and the drive is triggered accordingly. Furthermore, the drive may supply a negative propulsion torque. A value of a negative propulsion torque requested by the user or by the control and/or regulating system is determined and then used to determine a value of a corresponding negative internal torque to be supplied by the drive and the drive may be triggered accordingly.Type: GrantFiled: June 25, 2004Date of Patent: May 29, 2007Assignee: Robert Bosch GmbHInventors: Guenter Kettenacker, Juergen Saile, Ulrich Schopf, Hauke Wendt

Patent number: 5918579Abstract: A process and a device for controlling an internal combustion engine, specifically an internal combustion engine with self-ignition. Depending on different operating parameters, a signal determining the output power can be defined.
