Patent number: 5170769Abstract: The invention is directed to a system for electronically controlling (open loop and/or closed loop) an internal combustion engine of a motor vehicle. By means of at least one measuring unit at least one signal is generated representing the position of a power-determining component and the measuring unit comprises several sensors. The measuring unit is associated with a power-determining component of the vehicle such as a throttle flap or the control rod and/or accelerator pedal. The sensors are checked with respect to their functional capability by comparing the signal values generated by the sensors to each other with respect to a pregiven tolerance range. When a fault of one or more of the sensors is detected, then that sensor or those sensors which is or are unaffected can be determined.Type: GrantFiled: February 11, 1991Date of Patent: December 15, 1992Assignee: Robert Bosch GmbHInventors: Joachim Berger, Reinhard Fenchel, Thomas Kuttner, Dieter Seher, Klaus Bleuel

Patent number: 4688535Abstract: The invention is directed to an apparatus for influencing control quantities of an internal combustion engine by means of which vibrations of the entire vehicle in the lower engine speed range, particularly at idling, are to be eliminated. This is accomplished by allocating to each cylinder a regulating unit which regulates the control quantities influencing the respective cylinder, such as fuel metering, exhaust gas recirculation, start of injection, duration of injection, air/fuel ratio, ignition time point, et cetera, for the smoothest possible running condition.Type: GrantFiled: October 3, 1984Date of Patent: August 25, 1987Assignee: Robert Bosch GmbHInventors: Thomas Kuttner, Wolf Wessel

Patent number: 4630582Abstract: The invention is directed to an arrangement for rapidly adjusting an electromagnetic load associated with internal combustion engines. The output signals of two control systems are combined in a logic circuit such that priority is assigned to one of the two control systems. Dependent on the output signal of the higher-order control system, an evaluation circuit acts on a switch arrangement to thereby suitably influence the signal resulting from the combining operation of the output signals of the two control systems. This arrangement makes it possible to speed up the delivery of the output signal of the higher-order control system to the electromagnetic load which may be an injection valve, for example. The higher-order control system may be a smooth-running control system.Type: GrantFiled: October 17, 1984Date of Patent: December 23, 1986Assignee: Robert Bosch GmbHInventors: Thomas Kuttner, Max Straubel, Wolf Wessel

Patent number: 4538571Abstract: Disclosed a regulating device for a fuel volume adjuster of a self-igniting internal combustion engine. In order to damp jerking movements resulting at different power transmissions, a signal corresponding to the actual rotary speed of the engine is fed back into an electronic regulating circuit. Preferably, the feedback path includes a phase shifter. It is essential that the regulating action of the rotary speed be not delayed by the phase turning shifter. For this purpose, the electronic regulating circuit includes a PI stage and the fed back signal is applied to the regulating circuit only after its I-constituent has become effective.Type: GrantFiled: July 14, 1983Date of Patent: September 3, 1985Assignee: Robert Bosch GmbHInventors: Rainer Buck, Gerhard Engel, Thomas Kuttner, Wilfried Sautter, Wolf Wessel

Patent number: 4516550Abstract: An electronic control device is proposed for a Diesel fuel metering system, in which at the onset of the starting procedure, a constant fuel quantity is pre-specified at first, and this quantity subsequently increases in steps or in a ramp-like manner. Above a predetermined rpm or starting quantity, an rpm-dependent reduction in quantity takes place, to 90% of the full-load quantity. The open-loop or closed-loop control of the starting quantity ends upon the attainment of a speed of 800 rpm, for example. Both an analog and a computerized realization of the control device are provided, and the control device according to the invention is capable of dispensing with the processing of a temperature signal and can thus dispense with the use of one temperature sensor.Type: GrantFiled: May 7, 1984Date of Patent: May 14, 1985Assignee: Robert Bosch GmbHInventors: Rainer Buck, Thomas Kuttner, Fridolin Piwonka, Wolf Wessel

Patent number: 4467775Abstract: A method and an apparatus are proposed for controlling the quantity of exhaust gas recirculated from the exhaust gas system of an internal combustion engine to its intake side. The aspirated air quantity is compared with a set-point value formed in accordance with load and rpm, and if the deviation is greater than a minimum amount, control pulses for two magnetic valves are formed, which are triggered alternatively depending upon the polarity of the deviation and which further cause pressure to be delivered from two pressure sources having different pressure levels into the work chamber of a pneumatically functioning adjusting member of a dosing valve for exhaust gas recirculation. The opening duration of a given valve is dependent on the magnitude of the deviation from the set-point, and the valve remains completely open until a counteracting correction takes place if the deviation from the set-point exceeds a predetermined maximum amount.Type: GrantFiled: September 22, 1982Date of Patent: August 28, 1984Assignee: Robert Bosch GmbHInventors: Rainer Buck, Thomas Kuttner, Wolf Wessel

Patent number: 4359991Abstract: A fuel control system for an internal combustion engine with correction for optimum values based on a variety of factors. Characteristic engine data is stored in preferably digital memories with capabilities for interpolation. Upon addressing the engine data fields with input signals related to current operational variables, for example the accelerator pedal position, the control system derives therefrom a nominal air flow rate which is used as the reference value in a control loop that sets the amount of recycled exhaust gas and the fresh air flow. As the actual air flow rate approaches the reference value, the fuel flow is adjusted to insure correct mixtures at all times. In another embodiment, the fuel is supplied on demand but cannot exceed a maximum value except under special override conditions. Several other embodiments and variants are presented.Type: GrantFiled: January 26, 1981Date of Patent: November 23, 1982Assignee: Robert Bosch GmbHInventors: Gerhard Stumpp, Ludwig Walz, Gerhard Schielinsky, Wolf Wessel, Thomas Kuttner, Ulrich Flaig, Fridolin Piwonka, Hermann Eisele, Andreas Boehringer, Hans Kubach, Johannes Locher, Waldemar Becker
