Patent number: 10683789Abstract: A method is disclosed for determining a current temperature of a heating element with a PTC thermistor property (PTC) with which a urea-water solution for cleaning the exhaust gas in an internal combustion engine of nitrogen oxides can be heated. According to the invention there is provision that a correction factor is formed from the quotient of a minimum resistance of the heating element and of a minimum resistance of a reference heating element, in that a resistance which is determined at a current temperature of the heating element is multiplied by the correction factor, and in that the current temperature of the heating element is determined from the corrected resistance value and a temperature dependence of the resistance of the reference heating element. The method according to the invention permits more precise determination and regulation of the temperature of the heating element.Type: GrantFiled: February 2, 2018Date of Patent: June 16, 2020Assignee: Robert Bosch GmbHInventors: Petr Zeman, Florian Moldenhauer, Horst Kleinknecht, Marc Chaineux, Mathias Schwarz, Till Broestl

Publication number: 20180142594Abstract: A method for operating a reagent dosing system (12), in which at least one dosing valve (14) doses a reagent upstream of at least one SCR catalytic converter (16) which is arranged in an exhaust-gas duct of an internal combustion engine (10), in which method the reagent, which is stored in a tank (28), is heated by means of a heater (30), and in which method a cavity (44) in the region of the heater (30) is detected on the basis of the evaluation of a characteristic variable of a measure of the heating current (32). The approach according to the invention is characterized in that, in the event of a cavity (44) being detected, a notification signal (52) is provided.Type: ApplicationFiled: November 21, 2017Publication date: May 24, 2018Inventors: Marc Chaineux, Petr Zeman, Till Broestl, Tobias Hoeffken

Patent number: 8863500Abstract: A method for operating an electromagnetically actuated metering valve, which is loaded with a pulse-width modulated metering signal, which stipulates the dosage of a reagent or a precursor of the reagent introduced into the exhaust gas region of an internal combustion engine and an apparatus for implementing the method are proposed. A clock signal is provided, whose cycle duration is smaller than the cycle duration of the pulse-width modulated metering signal. The cycle duration of the pulse-width modulated metering signal is set as a function of a metering request signal to multiples of the cycle durations of the clock signal. The procedural approach according to the invention allows for a rapid adaptation of the dosage to the metering demands.Type: GrantFiled: September 17, 2008Date of Patent: October 21, 2014Assignee: Robert Bosch GmbHInventors: Jens Reinhold, Marc Chaineux

Patent number: 8249771Abstract: The invention relates to a method for detecting an error in a component assembly of a motor vehicle, the component assembly having a functional control unit and at least one function module to be controlled by the functional control unit as components. According to the method, a check is made by the functional control unit to determine whether a combination of individual errors is present for at least one component of the component assembly. When the combination of individual errors is thereby present, an occurrence of the error is verified by the functional control unit and a signal for implementing an emergency functional strategy is transmitted by said control unit to an engine control unit.Type: GrantFiled: May 7, 2009Date of Patent: August 21, 2012Assignee: Robert Bosch GmbHInventors: Bernhard Kurrle, Marc Chaineux, Andreas Feldges
