Patent number: 10002603Abstract: A system has a sound generator (20) that generates superimposed sound to a sound to be manipulated. An error sensor (50) measures sound and outputs a corresponding feedback signal (e?(n)). A signal generator (91) generates a sound signal (y(n)). A controller (92) generates a control signals (?1(n)) and (?2(n)). The adder (94) subtracts one control signal (?2(n)) from the feedback signal (e?(n)) and outputs a modified feedback signal (en(n)) to the signal generator (91). A weighter (95) weights the sound signal (y(n)) with the control signal (?1(n)) and outputs the weighted sound signal (y?(n)). The generated sound signal (y(n)) is a function of the modified feedback signal (e(n)). The controller (92) generates the control signals (?1(n), ?2(n)) such that a value of the amplitudes of the feedback signal (?e?(n)?) corresponds to a predefinable value (?).Type: GrantFiled: April 5, 2017Date of Patent: June 19, 2018Assignee: Eberspächer Exhaust Technology GmbH & Co.

Patent number: 9978356Abstract: A system includes a sound generator (20) that generates sound superimposed to sound to be manipulated. An error sensor (50) measures superimposed sound and outputs a corresponding feedback signal (e?(n)). A signal generator (91) generates a sound signal (y(n)). A controller (92) generates a control signal (?(n)) representing a value of a sequence of rational numbers. A weighter (93) weights the generated sound signal (y(n)) with the control signal (?(n)) and inverts it. An adder (94) adds the weighted/inverted sound signal to the feedback signal (e?(n)) and outputs a modified feedback signal (e(n)) to the signal generator (91). A weighter (95) weights the generated sound signal (y(n)) with the difference from one and with the control signal (?(n)) and outputs the sound signal y?(n). The generated sound signal (y(n)) is a function of the modified feedback signal (e(n)).Type: GrantFiled: April 5, 2017Date of Patent: May 22, 2018Assignee: Eberspächer Exhaust Technology GmbH & Co.

Publication number: 20140321659Abstract: A system (7), for influencing noises of a vehicle, includes a controller (9) and at least one connected loudspeaker (2) that generates noise inside a sound generator (3) in response to a control signal. The controller includes a microprocessor (91; 91?), a digital-to-analog converter (92), an amplifier (93), and a step-up converter (97). The microprocessor generates a digital control signal, to generate a noise to cancel noise inside an exhaust system and/or an intake system and/or to generate a noise inside an engine compartment. The digital control signal is converted by the digital-to-analog converter into an analog control signal. The amplifier amplifies the analog control signal output from the digital-to-analog converter. The step-up converter is connected to an automobile battery (10) of the vehicle and converts a battery voltage (VBATT) supplied by the automobile battery to a constant value, with this output as a supply voltage (VB) to the amplifier.Type: ApplicationFiled: April 24, 2014Publication date: October 30, 2014Applicant: Eberspächer Exhaust Technology GmbH & Co.

Patent number: 8333179Abstract: The invention deals with a method for operating an internal combustion engine with engine oil as the lubricant, wherein a fuel mass flow outgassing from the engine oil is ascertained and is taken into account via a map-based pilot control during the metering of a quantity of fuel supplied to the internal combustion engine and wherein a fuel/air ratio supplied to the internal combustion engine is determined. Provision is made in the method according to the invention for a mass flow offset determined from the deviation of the fuel/air ratio supplied to the internal combustion engine from a nominal value to be taken into account when the metering of the quantity of fuel supplied to the internal combustion engine occurs during an effective duration of the map-based pilot control.Type: GrantFiled: September 3, 2008Date of Patent: December 18, 2012Assignee: Robert Bosch GmbHInventors: Georg Mallebrein, Federico Buganza, Carlos Koster, Kai Jakobs, Juergen Pfeiffer, Emilie Hincker-Piocelle, Pierre-Yves Crepin

Patent number: 8312760Abstract: In the field of knock detection in a combustion engine, a method and a device detects and controls the knock by adapting the gain of an amplifier which amplifies the knock sensor signal. The gain of the amplifier is adapted based on analysis of a set of samples from the knock sensor so that the amplification of the knock sensor signal across the entire measuring window is optimum and the complete ADC evaluation range can be utilized better.Type: GrantFiled: May 6, 2009Date of Patent: November 20, 2012Assignee: Robert Bosch GmbHInventors: Federico Buganza, Carsten Kluth, Oskar Torno, Werner Haeming

Patent number: 8014933Abstract: The invention deals with a method to determine the fuel composition of a fuel mixture from a first fuel and a second fuel for the operation of an internal combustion engine, wherein the first and the second fuel have different octane numbers and wherein the internal combustion engine has at least one knock sensor and a closed-loop knock control. Provision is made according to the invention for the composition of the fuel mixture to be determined by means of an output signal of the knock sensor. Provision is made in many cases for the knock sensor to already be in the internal combustion engine, so that it does not present any additional expenditure of money or effort. Because the octane number of the fuel mixture is determined by the mixing ratio of the fuels involved, which have different octane numbers, in retrospect the composition of the fuel mixture can be suggested from the signal of the knock sensor under suitable operating conditions.Type: GrantFiled: July 17, 2008Date of Patent: September 6, 2011Assignee: Robert Bosch GmbHInventors: Klaus Joos, Georg Mallebrein, Federico Buganza, Carlos Koster, Helerson Kemmer, Kai Jakobs, Juergen Pfeiffer, Emilie Hincker-Piocelle, Werner Haeming, Pierre-Yves Crepin

Publication number: 20100198486Abstract: The invention relates to a method for operating an internal combustion engine, which can be operated with fuels and fuel mixtures of said fuels, said fuels differing from each other in the air quantity they require for a stoichiometric combustion. A fuel quantity to be supplied to the internal combustion engine is corrected via a mixture adaptation and a fuel adaptation, the mixture adaptation and the fuel adaptation being based on a lambda control and a fuel quantity contained in the fuel reservoir of the internal combustion engine prior to refueling and a fuel quantity supplied to the reservoir being determined.Type: ApplicationFiled: March 20, 2008Publication date: August 5, 2010Applicant: Robert Bosch GMBHInventors: Martin Streib, Georg Mallebrein, Federico Buganza, Kai Jakobs, Juergen Pfeiffer, Emilie Hincker-Piocelle, Pierre-Yves Crepin
