    摘要: The subject of the present invention is a motor control system having a monitoring circuit for monitoring PWM control for a DC electric motor, the PWM control comprising a power end stage having at least one field effect transistor, which controls the current at the DC electric motor. The motor control system is designed to monitor the current at the DC electric motor. The motor control system detects the voltage drop across the field effect transistor and comprises a temperature sensor for detecting the temperature of the field effect transistor. Furthermore, the motor control system is designed to determine the resistance of the field effect transistor from the detected temperature thereof, and to determine the current at the DC electric motor from the resistance of the field effect transistor and from the voltage drop across the field effect transistor.

    摘要: The belt retractor for an occupant restraint system has a frame, a belt spool having a pair of flanges and rotatably mounted in the frame and a locking mechanism for selective blocking of the belt spool. A wheel member provided with an external toothing is mounted on one flange of the belt spool. A locking pawl is biased by a spring that engages with the wheel member. During the normal operating state of the belt retractor, the locking pawl is held by means of a solenoid so that it is disengaged from the wheel member.

    摘要: The invention relates to a drive for a flap provided on a vehicle, especially an engine hood. The drive comprises an electric motor, an actuation shaft that is connected to the flap, and a reduction gear by means of which the rotor of the electric motor is coupled to the actuation shaft. The drive further comprises an energy accumulator by means of which the actuation shaft can be driven independently of the electric motor. The reduction gear is configured in such a way that the actuation shaft is driven in a rotational direction only by the energy accumulator and the electric motor drives the actuation shaft in an opposite rotational direction, thereby supplying to the energy accumulator an energy that is needed to drive the actuation shaft in the rotational direction. The invention further relates to a pedestrian protection means provided on a vehicle and equipped with such a drive.

    摘要: An arrangement for lambda control operates on an internal combustion engine (11) comprising a catalytic converter (12) and a lambda probe (13.v) mounted in front of the catalytic converter and a lambda probe (13.h) mounted behind the catalytic converter. The arrangement integrates by means of an integration means (15) the difference between the actual lambda value measured by the rear probe and the lambda desired value to which controlling is to be effected. The integration value is used as control desired value for a means (16) for lambda control. This arrangement and the associated method make it possible to control to the actually wanted lambda desired value even if the front lambda probe carries out incorrect measurements, for example because of hydrocarbons in the exhaust gas in front of the catalytic converter or, in the case of continuous-action control, faulty linearization of the probe characteristic.

    摘要: An electronic butterfly valve adjusting mechanism wherein the current supply to the adjusting motor (6), which is equivalent to the sum of all of the mechanical moments acting on the motor shaft, is monitored and a "window" is preselected within which the motor current/moment must lie if the butterfly valve and its adjusting components are operating normally. If, in the static case, the sum of all of the mechanical moments acting on the motor shaft is detected to be outside the "window" then it is concluded that a mechanical fault condition exists and the maximum possible angle of the butterfly valve is arranged to be reduced to a safe level. The driver can also be warned by a suitable visual signal.

    摘要: A control system for controlling the air/fuel ratio in an internal combustion engine 10, in which an oxygen probe (lambda probe) 13 is arranged in the exhaust gas of the internal combustion engine 10, has a control device 12 for continuous control. The actual value of the air ratio lambda is determined via a measured probe output voltage in conjunction with an at least approximately predetermined probe-characteristic relationship 16 between the value of the probe output voltage and the value of the air ratio lambda associated therewith. After forming the difference of desired value and actual value of the air ratio lambda, the air/fuel ratio is controlled on the basis of this difference. Such a control system is used primarily in order to reduce the total emission of the main pollutant components of the exhaust gas of an internal combustion engine. In particular in the case of an internal combustion engine 10 with catalytic converter arranged in the exhaust gas, a maintenance of the air ratio lambda as accurate as possible necessary for optimum efficiency of the catalytic converter (lambda=1) is assured.

    摘要: The invention is directed to a method and an apparatus for adapting the characteristic of a final controlling element to eliminate disturbances and other undesired influencing quantities and, particularly for adapting the controller characteristic for the idle air charge control of internal combustion engines. A desired air quantity value issued by a regulator on the basis of various operating conditions is corrected by multiplicative and/or additive action prior to being delivered to an idle control element, for example, by means of which a change is effected in the cross-sectional area of the opening of a bypass valve arranged in the fuel metering arrangement of the internal combustion engine. This correction relates to adapting a characteristic of the idle control element with respect to offset and slope. This is accomplished by evaluating the output signals of at least one offset integrator or one slope integrator to generate an adapted electrical actuating quantity for the idle control element. The integrators are released in dependence on operating conditions and receive an input differential signal obtained from the signal indicative of the desired air quantity value from the regulator and a signal indicative of the actual air quantity.

    摘要: An apparatus for optimizing operating characteristics of an internal combustion engine on the basis of torque variations based on a test signal, wherein the maximum output torque is determined directly on the basis of the torque signal and the specific fuel consumption is determined indirectly from the torque signal via the efficiency. Either the maximum output torque or the minimum fuel consumption is optimized, depending on the engine load range. Additional apparatus is described for simultaneously optimizing the ignition angle on the basis of torque signals, wherein individual test signals are associated only with individual cylinders or groups of cylinders and the corresponding torque variations relating to the individual cylinders are ascertained and processed.
