Patent number: 4359717Abstract: To increase the responsiveness of a vehicle alarm system to, for example, unauthorized entry through windows, jacking up for removal of parts or vehicle theft as well violent impact by another vehicle, at least one position sensitive sensor has its output signal, which represents the instantaneous position of the vehicle stored after activation of the alarm system. Any change in that position is detected and triggers a warning device when the deviation exceeds a predeterminable amount. The position sensitive sensor may be a fluid-filled vessel the internal resistance of which is measured in a resistance bridge or it may be a variable inductance sensor which is connected to a frequency generator whose output signals are counted and compared with a given value. The system according to the invention may also serve as an accelerometer.Type: GrantFiled: February 14, 1980Date of Patent: November 16, 1982Assignee: Robert Bosch GmbHInventors: Bernd Huber, Erich Schneider, Helmut Fleischer

Patent number: 4353272Abstract: The engine is controlled by sensing fuel pedal position, indicative of desire engine power. A characteristic transmission data field is used to select the appropriate gear or gear ratio. The engine is controlled on the basis of characteristic engine data or on the basis of an engine operating curve associated with minimum fuel consumption in dependence of the changes in engine speed due to the changing transmission ratio. In normal driving, the apparatus selects operation along the minimum fuel curve whereas during periods of increased power demand, the apparatus operates in dependence of characteristic engine data. Also proposed is apparatus which takes account of the operational vehicle status and effects the switchover from optimum fuel consumption to optimum power delivery with priority assigned to optimum fuel economy.Type: GrantFiled: November 17, 1979Date of Patent: October 12, 1982Assignee: Robert Bosch GmbHInventors: Erich Schneider, Helmut Fleischer, Helmut Rembold, Alexander Witte

Patent number: 4337511Abstract: A digital control apparatus for the running speed of a motor vehicle having an actual-value source, a memory for a demand-value which is proportional to the desired running speed, comparison means for executing an actual-value/demand-value comparison, and a setting device controlled by the output of the comparison means for controlling the throttle flap of an engine. Upon the actuation of a switch, the actual value is transferred into the demand-value memory apparatus and represents the running speed. To change the running speed by means of the control apparatus there is provided a second and auxiliary demand-value memory apparatus in which a ramp function is producible by means of a digital counting process. The given ramp value presents a supplementary demand-value during such an alteration of the running speed, i.e. the old running speed value is transformed into the new running speed value with the aid of the supplementary demand value.Type: GrantFiled: March 15, 1980Date of Patent: June 29, 1982Assignee: Robert Bosch GmbHInventors: Erich Schneider, Helmut Fleischer, Wolfgang Nonnenmann, Benno Gerum

Patent number: 4264849Abstract: To improve the speed and simplicity of adjustment of mechanical devices, for example passenger seats and other movable members in motor vehicles, there is provided a closed-loop control system in which servo-motors adjust the final positions of the movable members. The desired configurations, i.e. the positions of the individual members of the device are stored in one or more memories for recall upon the actuation of push-buttons. The same push-buttons are used alone or in conjunction with a data storage switch to store new positions in the memory. The servo-motors are coupled to transducers which generate an electrical signal related to the position of the servo-motors and their associated movable members. Upon actuation of one of the push-buttons, the device is adjusted until the control deviation is near-zero, i.e. until the signal from the transducers conforms to the data stored in the memory.Type: GrantFiled: July 12, 1978Date of Patent: April 28, 1981Assignee: Robert Bosch GmbHInventors: Helmut Fleischer, Erich Schneider

Patent number: 4188926Abstract: A servo control system is used to supply a command position signal to control the throttle opening of the engine, and hence vehicle speed. To permit increase of amplification without instability of the positioning control loop when sensing throttle position and feedback of the throttle position error signal, the feedback signal is degressively nonlinearly related to absolute throttle position in order to match the nonlinear throttle position-torque characteristics of automotive type internal combustion engines. The non-linear relation is obtained with a minimum of external connections by connecting a resistor to a source of fixed supply which is connected to the slider of a potentiometer having one terminal unconnected and the other terminal connected to ground or chassis. Only two supply lines to the throttle positioning sensor are needed, namely one for the resistor to a source of supply and the other for the variable resistor take off from the slider.Type: GrantFiled: November 28, 1978Date of Patent: February 19, 1980Assignee: Robert Bosch GmbHInventor: Helmut Fleischer

Patent number: 4169437Abstract: A speed control system for a vehicle, especially an internal combustion powered vehicle, includes a driver-settable member which has up to four distinct regions of adjustment, namely idling, deceleration, cruising and acceleration. The cruising region includes a mechanical or other pressure point to provide a sensible signal to the operator of the vehicle indicating the constant speed region. The apparatus of the invention prescribes a function generator which generates a voltage as a non-linear function of the driver-settable member and supplies it to a voltage-controlled oscillator. The output signal of the oscillator is fed to an integrating stage whose direction of integration is controlled by suitable logical circuits which detect the region occupied by the driver-settable member and the difference between the set-point value supplied by the integrator and the actual vehicle or engine speed. Other circuitry controls idling rpm.Type: GrantFiled: November 22, 1977Date of Patent: October 2, 1979Assignee: Robert Bosch GmbHInventor: Helmut Fleischer

Patent number: 4120373Abstract: A motor drives a fuel supply control element, typically the throttle of an automotive-type gasoline engine through a solenoid controlled coupling. Upon brake, clutch, manual switch, or other interrupting operation, the solenoid is de-energized so that a spring can permit interruption of the coupling and a throttle return spring can return the throttle to idle position. To prevent dangerous conditions from arising, and run-away of the engine in case of malfunction of the coupling, an electronic circuit is provided to introduce a signal to the speed control system which tends to move the throttle positioning motor to change the position of the throttle to idle speed condition if a disabling signal is sensed.Type: GrantFiled: February 22, 1977Date of Patent: October 17, 1978Assignee: Robert Bosch GmbHInventor: Helmut Fleischer

Patent number: 4117355Abstract: To obtain input signals as a function of various types of input signals, R/C circuits are used to charge or discharge a capacitor, the charge state of which is sensed by a threshold stage. To render such circuits essentially independent of temperature changes, in spite of different response levels of the R/C circuit and the threshold stage, a second R/C circuit and threshold stage are connected in parallel with the first, one threshold stage being responsive to charging direction of the capacitor, the other threshold stage being responsive to discharging direction of the capacitor, and the overall output signal being a combination of the output signal from both threshold stages so that increase of the signal components of the combined output signal from one threshold stage, due to temperature increase, for example, will be balanced by a decrease of the signal component from the other threshold stage, thereby rendering the overall output essentially temperature independent.Type: GrantFiled: March 11, 1977Date of Patent: September 26, 1978Assignee: Robert Bosch GmbHInventor: Helmut Fleischer

Patent number: 4098367Abstract: To provide for digital storage of a command signal commanding a predetermined speed of the speed control system, a digital counter is provided forming a memory, connected to an analog-digital converter to generate a derived command signal in dependence on the counted state of the counter. Stray signals which may affect the count state of the counter thus can only change the time at which the counter reaches its predetermined count state, and not the count output thereof, whereas such stray pulses might otherwise affect the command signal. The counter holds the commanded speed as a count number.Type: GrantFiled: September 10, 1976Date of Patent: July 4, 1978Assignee: Robert Bosch GmbHInventor: Helmut Fleischer

Patent number: 4092853Abstract: The time duration of output pulses from the transducer, including wave-shaping circuits, if used, is measured and compared with respect to predetermined time limits. Two sequential pulses are measured and stored. If both pulses are shorter than a predetermined time interval, no alarm signal is generated; if the first pulse is longer than a predetermined time interval and the second also longer than a predetermined time interval, an alarm signal generation circuit, otherwise activated by the second, longer signal, is inhibited (since acceleration or deceleration of the wheel is indicated); if, however, the time duration of the second sequential pulse is longer than a predetermined time interval, but the time duration of the preceding pulse is shorter than its time duration threshold value, the malfunction signal is not inhibited, indicative of malfunction, loose contacts, or the like.Type: GrantFiled: October 18, 1976Date of Patent: June 6, 1978Assignee: Robert Bosch GmbHInventors: Erich Schneider, Eberhard Schnaibel, Helmut Fleischer

Patent number: 3972568Abstract: A wheel brake anti-lock system comprises a circuit which senses which one of the front wheels turns faster than the other and, in dependence on sensed applied braking fluid pressure, as controlled by the operator, the anti-lock system bases its control characteristics on either the faster, or the slower one of the wheels, thereby favoring either braking effort, or steering and attitude control; when the braking pressure is high, commanding fast stops, braking effort is favored; when the braking pressure is low, attitude control is favored, thus preventing skids on differentially slippery surfaces with respect to the right and left wheels of the vehicle.Type: GrantFiled: May 30, 1975Date of Patent: August 3, 1976Assignee: Robert Bosch G.m.b.H.Inventor: Helmut Fleischer
