摘要:
A method for detecting the readiness for operation of an oxygen measurement sensor which is located in the exhaust pipe of an internal combustion engine and serves, together with a regulating device, to regulate the preparation of the mixture for the internal combustion engine. The voltage present at the oxygen measurement sensor is measured in succession for two different conditions of load and the internal resistance is calculated from the results of the measurement and compared with a predetermined value.

An electric device for eliminating the jerking of vehicles, particularly automotive vehicles with internal combustion engines and with a control member which influences the intake thereof, and particularly idle-speed intake measures are taken in order for the jerk speed of rotation to run through automatically, that is it cannot be continuously set by the driver by any position of the gas pedal. For this purpose there are provided means for detecting the actual speed of rotation, means for comparing the actual speed of rotation with the set jerk speed of rotation as well as limiting means for producing a signal within a predetermined rotary speed range, which signal controls the control member, within which rotary range is the jerk speed of rotation. These means are developed such that the control member causes an intake which increases with the actual speed of rotation, within the critical speed of rotation range.

In an idling controller, particularly for automotive vehicles, there are present both a control amplifier with integral time portion (3) and a limiter (6) with proportional time portion. The inputs of the limiter are acted on by the correcting variable from the output of the control amplifier and by a limiter reference variable formed with the actual-speed value. The output of the limiter is fed back to an input of the control amplifier. In order to obtain the desired time action of the idling controller upon sudden drops in speed, at least one time member (12) with differential time portion is provided between the input (1) of the actual-speed value and the output of the limiter (6). The limiter (6) is so dimensioned and coupled with the output of the control amplifier (3) that, upon a drop in speed beyond a predetermined value, the correcting value (y) is controlled by the output variable of the limiter (6) (control limit).

A device for the control of the traveling speed of a motor vehicle with a regulating unit actuateable by the vehicle driver, particularly a gas pedal, and means for transmission of the movement of the same to an element, particularly the throttle valve, which influences the fuel-air mixture. An electrical controller is provided, the desired value input of which is applied with the output signal of a first electrical position indicator, the latter being coupled with the regulating unit and the actual value input of which is applied with the output signal of a second electrical position indicator, the latter being coupled with the setting member or positioning actuator of an electrical setting or adjusting device, the actuator standing in connection with the element which influences the air-fuel mixture. Upon actuation of the brake or clutch, a coupling device, between a servomotor of the electrical controller and the actuator, is disconnected for a short time.

A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver, the gas pedal emitting an electrical signal, the gas pedal being connected with the desired value input of an electrical controller, the output signal of which acts on a positioning actuator, the latter being coupled with the element, particularly the throttle valve, which influences the fuel-air mixture, the instantaneous setting position of the positioning actuator being transmitted as an electric signal to the actual value input of the controller. The actual value input or the desired value input of the controller is driven by a circuit which produces a signal for influencing the position of the throttle valve, which signal is dependent on at least one factor to be monitored.

The invention relates to a holding device for balancing disk-like inertial bodies, which comprises at least two clamping elements (8) centered on a center axis (A), such elements (8) having a respective radial abutment face (34), wherein the clamping elements (8) are provided on a connecting part (10) having at least one elastically deformable portion, which connecting part produces an equal shift of all clamping elements (8) on deformation. A connecting part (10) with the clamping elements (8) is provided on an elastically deformable wall (6), which is constituted by a thin-walled diaphragm (6) extending in a radial plane in relation to the center axis (A), such diaphragm being arranged coaxially in relation to the connecting part (10) and the clamping elements (8). Via a pressure chamber (12) formed in the holding device it is possible for both a vacuum and also gage pressure to be applied in order to deform the diaphragm and accordingly to cause both a radial and also an axial shift of the clamping elements (8) arranged on the diaphragm (6).

A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver and giving off an electrical signal, the regulating member being connected with the desired-value input of an electrical controller, the output signal of which acts on an adjustment actuator. The latter is coupled with the element which influences the fuel-air mixture, particularly the throttle valve, and the instantaneous position of the adjustment actuator is transmitted as an electric signal to the actual-value input of the controller. A correction circuit is connected with the actual-value input or the desired-value input of the controller. For the correction of the throttle-valve displacement which is dependent on the regulating member, this circuit produces a signal which is a function of one or more operating parameters which are related to the fuel consumption.

摘要:
A device for disconnecting the feed of fuel to an internal combustion engine with an injection pump during the coasting of an automotive vehicle comprises a solenoid valve for disconnecting and reconnecting the feed of the fuel. The valve is controlled by the decrease in the speed of the internal combustion engine. In order to adapt the disconnect threshold and the reconnect threshold of the feed of the fuel to the characteristic curve of the internal combustion engine at little expense but nevertheless with a large saving in fuel, the solenoid valve is connected to an outlet line of an idle-speed controller which is provided for the same internal combustion engine. The time response of the controller has at least a differential portion in addition to a proportional portion, but possibly proportional, integral and differential portions. The adaptation of the time response portions to the dynamic behavior of the internal combustion engine is the same as for the control for the idling speed.
