Abstract: According to the invention, an in-vehicle device for evaluating received position signals from at least one transmitter located outside a vehicle is proposed, which from subsequently ascertained position data determines various motion parameters of the vehicle. These motion parameters, such as the vehicle speed, acceleration, and change in rotational and directional angles are used to control devices for the vehicle or the engine. For instance, from the ascertained speed signal, an ABS brake system [!] or a vehicle speed limiter [cruise control?] can be controlled. Alternatively, the motion parameters can be output on a display.

Abstract: In a brake system with electromechanical actuation, a test run is carried out when the vehicle is started, in the course of which at least one wheel brake is acted on by a control signal, which corresponds to a predetermined minimum braking action. If this minimum braking action is not reached in any one of the wheel brakes, the parking brake is not unlocked.

Abstract: The invention is directed to a method and an arrangement for controlling a brake system wherein the electrically actuable actuator for the wheel brakes is actuated in the context of a closed-loop control in normal operation. A transfer from the closed-loop control to an open-loop control of the actuator takes place with entry into at least one pregiven operating state, especially an operating state with low wheel rpm.

Abstract: The extent to which the brake pedal is actuated is detected, and the braking action in the wheel brakes with the greater amount of wear is reduced as a function of this pedal actuation. The reduction in brake pressure takes place primarily in a low range of brake pressures, the amount of reduction decreasing continuously in a middle range of brake pressures, and not taking place at all at high brake pressures.

Abstract: A slip-controlled brake system for commercial vehicles with a hydraulic transmission device for which the cost of the system is reduced. Each axle of the vehicle is assigned a hydraulic control unit, with an electronic control unit, of a slip-control device for passenger vehicles. The hydraulic control unit has four hydraulic channels (K1, K2, K3, K4). Brake lines which connect a master cylinder of the brake system to wheel cylinders are routed in each case via two channels (K1, K2, K3, K4) of the hydraulic control unit, which are connected in parallel, in order to achieve a sufficiently large volume flow of pressure medium. Connected to the corresponding control unit are two wheel speed sensors assigned to the wheels of the respective vehicle axle. The control units are connected electrically for the exchange of wheel speed sensor signals. The brake system can be implemented in an advantageous manner on light commercial vehicles.

Abstract: A system for chassis control, specifically of passenger cars and trucks, where the control parameters of the controlled loop are varied for control of the chassis properties in contingence on the state of travel of the vehicle as determined by sensors. Specifically determined for recognition of the state of travel are parameters representing the vertical-dynamic state of movement of the vehicle and/or the individual driving style of the operator. This procedure is based upon the relative movements between the vehicle body and at least one wheel, captured by sensors.

Abstract: An adjustable engine mount for shielding a vehicle body from oscillations of a drive unit, in which the magnitude of the damping and of the spring rate is controlled as a function of control signals of an electronic control unit. For adjusting the damping, the engine mount has an actuating device, by means of which the size of a throttle cross section between a first chamber and a second chamber of a damping chamber can be adjusted. For adjusting the spring rate, the engine mount has an air cushion which functions like a pneumatic spring element, which can be inflated and vented via a valve device. The electronic control unit has inputs for various input signals, which describe parameters that influence the motion of the drive unit relative to the vehicle body. The electronic control unit controls the damping and the spring rate of the engine mount as a function of the magnitude of at least one of the input signals.

Abstract: A device for controlling ignition or fuel injection and the like of an internal combustion engine includes an angular position sensor of a shaft of the engine. The sensor is in the form of a disc rotating together with the shaft and being provided on its periphery with as many radially projecting segments separated by gaps as many cylinders has the engine. A gap between the segments is provided with a single sloping ramp terminating with a steep flank. The flank of one segment and the steep flank of the ramp cooperate with a detector which generates a marking pulse coordinating during single rotation of the shaft the distribution of control pulses to respective cylinders.

Abstract: A device for controlling an internal combustion engine of a motor vehicle comprises a sensor disk rotating with the shaft of the engine and a stationary signal receiving element scanning signals from the sensor disk. Sensing elements are positioned on the sensor disk. The number of these elements is proportional to the number of cylinders of the engine. Each sensing element includes a sickle-shaped portion and a lug coordinated with the signal receiving element. The control system is formed as an assembly of prefabricated structural components.

Abstract: An overvoltage protection circuit is galvanically, directly connected across at least part of the secondary winding in the ignition system of an internal combustion engine. The input portion of the overvoltage protection circuit is a voltage divider preferably constituted by RC elements. The voltage at the tap of the voltage divider is applied to a Schmitt trigger. When the voltage across the secondary winding becomes excessively high, the Schmitt trigger output pulse triggers a monostable multivibrator whose output pulse in turn increases the conductivity of a transistor switch located in series with the primary. The increase in primary current tends to oppose further increases in primary and secondary voltages. Alternatively, the output from the multivibrator could be used to shorten the time of current flow in the primary winding in subsequent ignition time intervals or to completely block any subsequent ignition process.

Abstract: An inductive transducer having an electromagnetic inductive pickup coil in flux linking relationship to a rotary electromagnetic armature provides spaced output pulses to control current flow, and subsequent interruption of current through an ignition coil; to automatically increase the time during which current can flow through the coil, and change ignition timing, an impedance load circuit is connected to the inductive transducer through a control switch, so that the output characteristic of the inductive transducer is changed when the control switch is operated; the control switch may be speed dependent, or automatically speed dependent by the inclusion of a Zener diode which becomes conductive when the output voltage from the transducer rises, for example as speed of the engine, and hence of the transducer increases.

Abstract: A switch connected in series with the ignition coil is "on" and "off," respectively, in the presence and absence of a pulse furnished by a pulse generator operating in synchronism with the crankshaft of the engine. If the pulse width of the pulses is too small for the current in the ignition coil to reach the minimum value required for ignition, the closing time of the series switch is advanced, while if the pulse width is too long, causing excess heat dissipation in the coil, the closing time of the switch is retarded. To accomplish this, a first digital counter counts downwards for a predetermined time and upwards for a time period in which the current in the ignition coil exceeds a predetermined current. Upon interruption of the current in the coil, the then-present value in the first digital counter is transferred to a second digital counter. The second counter then counts down at a predetermined rate until a predetermined count is reached.

Abstract: An arrangement is described for assuring a parallel, evenly-spaced relationship among a succession of rod-shaped fasteners, illustratively nails, to be joined by an extruded plastic ribbon and thereafter molded into a nail strip suitable for use in pneumatic nail drivers and the like. A succession of grooves formed in a transfer chain that receives and advances a succession of the nails in a first plane is conventionally contacted by an elongated support means which bears against a first plurality of the grooves on the chain to capture the nails in the grooves. A second pressure member of smaller longitudinal extent than the support member is resiliently mounted in inwardly overlapping relation to the support member adjacent and upstream of the molding portion of the apparatus for contacting the shafts of the captured nails immediately before such nails and the adhered plastic ribbon are molded into the strip.
