Patent number: 6386180Abstract: A method and an arrangement for operating internal combustion engines is suggested which is operated in at least one operating state with a lean air/fuel mixture. The fuel mass, which is to be injected, or the injection time, which is to be outputted, is determined in dependence upon a desired value. For monitoring the operability, the actual torque of the engine is determined on the basis of the fuel mass, which is to be injected, or the injection time, which is to be outputted, or the outputted injection time and compared to a maximum permissible torque and a fault reaction is initiated when the actual torque exceeds the maximum permissible torque. Parallel to the above, a quantity, which represents the oxygen concentration in the exhaust gas, is compared to at least one pregiven limit value and a fault reaction is initiated when this quantity exceeds the limit value.Type: GrantFiled: November 9, 2000Date of Patent: May 14, 2002Assignee: Robert Bosch GmbHInventors: Juergen Gerhardt, Arndt Ehrlinger, Torsten Bauer, Winfried Langer, Frank Bederna, Ulrich Schopf

Patent number: 5335178Abstract: The invention relates to a method for filtering out disturbances in the form of short term wheel acceleration signals when the wheel exhibits an overall deceleration, so that a more accurate deceleration signal can be used for control of drive slippage.Wheel speed v is measured at intervals T.sub.A and speed changes for each interval are determined. When a change is negative or zero following a positive change in a previous interval, the wheel speed is stored as a maximum speed v.sub.max while v continues to be measured and a counter determines the period of time .DELTA.t between the occurrence of v.sub.max and the instantaneous value v. Beginning at a predetermined filtering time .DELTA.T after storing v.sub.max, a quotient .DELTA.v/.DELTA.t representing the filtered slope of the value v is determined and used as a control variable to regulate wheel slippage.Type: GrantFiled: October 21, 1991Date of Patent: August 2, 1994Assignee: Robert Bosch GmbHInventors: Jochen Schafer, Thomas Frank, Frank Bederna

Patent number: 5320076Abstract: The invention is directed to an arrangement for detecting the position of an accelerator pedal and/or a power-determining element of an internal combustion engine of a motor vehicle. The arrangement has at least two measuring devices as well as monitoring means which check the function of these measuring devices on the basis of the measuring signals thereof. In addition, a further measuring device in the form of a switch element is provided which likewise generates a signal representative of the position of an accelerator pedal and/or power-determining element of an internal combustion engine of a motor vehicle. A microcomputer selects on the basis of all three measuring signals at least one of the measuring signals for controlling the drive power of the engine in a motor vehicle.

Patent number: 5224453Abstract: A system for the open-loop and/or closed-loop control of an internal combustion engine is suggested at least dependent upon signal values which represent the position at least of one element influencing the power of the internal combustion engine and which are determined by a measuring device for detecting this position. This measuring device includes several sensors which each detect the position of the same element. On the basis of the signal values generated by the sensors, a first malfunction detection is carried out as to whether the signal values with respect to each other lie in a first pregiven value range. A second malfunction check takes place especially in the idle or near-idle region of the position of the particular element as to whether the signal values individually and/or to each other lie in a pregiven second value region. In this connection, the second malfunction check is less sensitive than the first.Type: GrantFiled: October 10, 1991Date of Patent: July 6, 1993Assignee: Robert Bosch GmbHInventors: Frank Bederna, Alois Hils
