Patent number: 11970169Abstract: An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.Type: GrantFiled: June 17, 2022Date of Patent: April 30, 2024Assignee: ZF CV Systems Europe BVInventors: Steffen Gerlach, Alexander Rodenberg, Michael Schomburg

Patent number: 8348498Abstract: A procedure for checking the functionality of an electric heating device (10) with at least one PTC-element (13, 14) is suggested. The electric heating device (10) is operated at a battery voltage. When controlling the heating device (10) it is impinged with a current and at least one measuring value is detected, which represents the current that flows through the heating device. The measuring value for the current is compared to at least one reference value with a default tolerance width while considering the battery voltage. In the case of a measuring value that deviates from the reference value an error can be assumed.Type: GrantFiled: November 20, 2009Date of Patent: January 8, 2013Assignee: Robert Bosch GmbHInventors: Buelent Barcin, Jan Kaluza, Michael Gerlach, Horst Kleinknecht

Patent number: 8104268Abstract: A method for operating a metering valve and a device for performing the method, providing for diagnosis of the metering valve which defines a flow rate of a reagent to be introduced into an exhaust gas area of an internal combustion engine. The diagnosis is performed on the basis of an analysis of a measure for the flow rate during a diagnosis time. According to a first embodiment, after a diagnosis start signal has occurred with the metering valve closed, the reagent is brought to a predefined diagnosis starting pressure via a pump; the metering valve is then set at a predefined flow rate and the pressure difference occurring during the diagnosis time is analyzed. According to another embodiment, the amount of reagent delivered by the metering valve during the diagnosis time into a graduated beaker is analyzed.Type: GrantFiled: December 8, 2004Date of Patent: January 31, 2012Assignee: Robert Bosch GmbHInventor: Michael Gerlach

Patent number: 7617674Abstract: A method for operating an exhaust-gas treatment device of an internal combustion engine and a device for carrying out the method, in which a reagent, whose pressure is measured by a reagent pressure sensor, is introduced into the exhaust-gas area upstream from the exhaust-gas treatment device. First the reagent pressure is brought to the exhaust-gas pressure which prevails in the exhaust-gas area upstream from the exhaust-gas treatment device. Then the pressure difference between the reagent pressure and the sum of the exhaust-gas pressure and the ambient air pressure is compared to a predefined pressure difference threshold, and if the pressure difference threshold is exceeded an error signal is supplied. The procedure contributes to an exact metering of the reagent through a diagnosis of the reagent pressure sensor.Type: GrantFiled: October 20, 2005Date of Patent: November 17, 2009Assignee: Robert Bosch GmbHInventor: Michael Gerlach

Publication number: 20070163238Abstract: A method for metering a reagent into the exhaust gas flow of an internal combustion engine is provided, in which the reagent is guided in at least one component and in which a measure for the temperature of the component is recorded. The measure for the temperature is compared to a predefined temperature threshold value. A counter counts the number of times the threshold is exceeded. If the counter state exceeds a predefined count threshold value, a service signal is emitted. The temperature threshold value is fixed, for example, at the freezing temperature of the reagent. One embodiment provides that the counter counts an exceeding of the temperature threshold value only when the component is filled with the reagent.Type: ApplicationFiled: March 11, 2004Publication date: July 19, 2007Inventor: Michael Gerlach
