Title: Fault diagnosis of IC engine exhaust gas recirculation system - detecting pressure change when control valve is operated, and checking whether cooling water temp., air intake temp. or engine oil temp. are above reference for correct operation of sensor
Inventor: UCHINAMI MASANOBU
IPC: F02M25/07
Filed: 1993-08-05
Abstract: A feedback valve is periodically operated during operation of the engine so that a pressure sensor forming part of the control system can determine whether a resulting pressure change within the air inlet system or exhaust gas outlet system lies within a defined range. A fault is diagnosed depending on the outcome of this test. A switch-on step is used to decide whether the pressure sensor can operate normally taking account at least of the cooling water temp., inlet air temp. or engine oil temp. compared to a lower operating threshold when the engine is started. The fault diagnosis is declared invalid if the temp. is too low. ADVANTAGE - Eliminates faulty diagnosis, e.g. in freezing conditions.
Patent DE-4326604-A1 (DE)
Title: Classifying device
Inventor: STEIN JUERGEN DR ING
IPC: B03B5/60
Filed: 1993-08-07
Abstract: The object of the invention is already to balance out the flow of the fluid with the solid material dispersed therein flowing to the deflector wheel outside the flow ducts of the deflector wheel and to accelerate it to the circumferential speed of the deflector wheel. This is achieved by construction elements which rotate together with the deflector wheel, e.g. by coaxially arranged annular discs which extend radially outwards from the circumferential region of the deflector wheel. The gradual acceleration of the fluids to the circumferential speed of the deflector wheel is achieved by the carrier effect of the boundary layer of the fluid adhering to the surfaces of the annular discs, it being possible for the magnitude of the carrier effect to be influenced by the selection of the number, spacing and/or diameter of the annular discs.

Title: Hydraulic stabiliser control
Inventor: ZAPF FRIEDRICH
IPC: B60R16/08
Filed: 1993-08-12
Abstract: The invention is based on a hydraulic stabiliser control with a hydraulic actuator which is assigned to a front stabiliser and with a hydraulic actuator which is assigned to a rear stabiliser of a motor vehicle, a first actuator of the two hydraulic actuators being capable of being supplied with fluid from a pressure source via a pressure line and the first pressure which can be fed to the first hydraulic actuator being adjustable by means of a proportional pressure-limiting valve which is connected to the pressure line. In a known stabiliser control, a flow divider and a second proportional pressure-limiting valve are additionally provided so that the second hydraulic actuator can be fed with a second pressure which is completely independent of the first pressure. The object of the development is to provide a cost-effective, hydraulic stabiliser control. This goal is achieved in that in a hydraulic stabiliser control with the features of the preamble of Claim 1 a permanently set pressure control valve can be additionally connected to the pressure line and that the second hydraulic actuator can be fed from an output of the pressure control valve with a second pressure which is lower than the first pressure and is dependent in its strength on the strength of the first pressure. In a hydraulic stabiliser control according to the invention, a flow divider and a ... in comparison with the known control ... Original abstract incomplete.

Title: Method and arrangement for detecting zero crossing of the fundamental wave of periodic AC voltages subject to frequency fluctuations
Inventor: WEBER JOCHEN DIPL ING
IPC: G01R19/175
Filed: 1993-08-20
Abstract: The invention relates to a method for detecting the zero crossing of the fundamental wave of periodic AC voltages subject to frequency fluctuations, in which the transmission response of filter circuits in the resonant range is employed. In order to design a method which automatically detects r.m.s. variable and frequency deviations, corrects the latter via phase relationship and thereby makes possible exact zero-crossing detection of periodic sinusoidal, rectangular or triangular quantities, even in the case of variable frequencies within defined ranges, and which furthermore works only with AC voltages between +/- 15 V maximum, it is proposed according to the invention to make use of an active band-pass filter (3) with variable resonant frequency (f0), the resonant frequency (f0) of which is matched to the frequency fluctuations or alterations of the AC voltage (UEX) to be evaluated such that the phase relation between AC voltage (UEX) to be evaluated and the output signal (NDG) of a 1st Schmitt trigger (6), with inverted output, connected downstream of the band-pass filter (3) remains constant, the resonant frequency (f0) being matched via a PLL circuit (4) outputting a control frequency (fCLK). Advantageous refinements of the method and arrangements for carrying out are described. <IMAGE>

IPC: B62D5/065
Filed: 1993-11-08
Abstract: The hydraulically actuated steering device for a vehicle, in particular for its front wheels, has a pump (10) which is driven by an electric motor (13) and also charges a pressure accumulator (16) connected to the feed line. When a prescribed pressure is reached, the electric motor is switched off. The steering cylinder (30) has a double-acting piston with piston rod (29) which has a toothing (31) with which the toothed pinion (33) arranged on the steering spindle (33) intermeshes. The steering spindle is mounted in a link bearing (35) which has a specific axial freedom of movement. This bearing interacts with two seat valves (24, 27) which are located one opposite the other and control the provision of the pressure medium fed by the pump to the pressure spaces (30A, 30B) of the steering cylinder. Furthermore, a slide valve (57) is provided which controls the feeding of the pressure medium from the pressure spaces of the steering cylinder to the vessel. In this way, a very compact control valve device and economical actuation of the steering device are obtained. <IMAGE>

A second external temperature value (18) winter can be set below which the heat generator should operates with 100% output. The control device produces a second signal (b) which lies between 0% and 100% output according to the external temperature and the set external temperature values. The control device combines the two signals to form it control signal (d) for the control and regulating apparatus for the heat generator.

Title: Device and method for the control of a starting device of a vehicle drive
Inventor: FOELDI THOMAS DIPL ING
IPC: B60W10/04
Filed: 1994-03-17
Abstract: The invention is intended to create a device and a method for the control of a starting device, which represent an improvement in terms of the account taken of the driver's wishes on the one hand and the vehicle's environment on the other. For this purpose the starting sequence is performed in two phases, that is in a first phase in which the input speed is brought to a set speed, and an ensuing second phase in which a differential speed signal, formed from the difference between input speed and output speed, is adjusted to a predetermined set curve down to the value zero. The first phase begins when the starting device is not completely closed and the position of the power control element lies below a certain limit. During the first phase the set speed is first of all determined as a function of the position of the power control element, the rate of change of the position of the power control element and a signal describing the driving style of the driver. By means of the set speed thus determined a set curve of a control signal for an actuator of the starting device is then determined so that the said set speed is also attained in the current position of the power control element. The second phase of the starting sequence begins when the input speed signal has virtually attained the set speed or when a predetermined speed of travel is attained. In the second phase ...
