    摘要: A sensor arrangement and engine management device for a combustion engine, the engine management device including the sensor arrangement for detecting variables indicative of engine load, a mechanism for determining engine load on the basis of measured values supplied by the sensor, as well as a throttle-valve position control loop. At least two of the sensors of the sensor arrangement, which may include a mass air-flow sensor, an intake-air temperature sensor, an induction-pipe pressure sensor, and a throttle-valve position sensor, are microintegrated in a modular unit. The engine management device is made such that a sensor device with the at least two sensors, the mechanism for determining, engine load and/or the throttle-valve position controller used in the throttle-valve position control loop are microintegrated in a modular unit. The engine management device can be used, for example, for controlling a spark ignition engine in a motor vehicle.

    摘要: In a process for establishing the driving direction of a vehicle by an electronic compass fixedly mounted in the vehicle and which is provided with a magnetometer having a computerized evaluation circuit the local curve (O) of the earth field (He) is determined from five measuring points (M1 . . . M5) which are established by turning the vehicle and corresponding signals are stored. The parameters for the center point displacement (Hs), the shape (ellipse) and the turning (angle .alpha.) of the local curve (O) in the vector diagram (x,y) are calculated by the computer by means of an algorithm with five unknowns for the five measuring points and thereafter the direction of the earth field (He) is computed. Subsequently, the vehicle is oriented to a predetermined cardinal direction and a correction angle is determined from the difference of angles between the cardinal and north directions and the earth's magnetic field direction measured by the compass. In the subsequent measurements the correcting angle is then taken into consideration when establishing the driving direction (.phi.) from the local curve (O).

    摘要: A process for correcting inclination dependent angle errors when establishing the driving direction of vehicles with an electronic compass for navigation is suggested. The compass comprises a magnetometer (10) with an evaluation circuit (11) for computing the driving direction. For compensating inclination dependent angle errors on the indicator of the drive direction the inclination angle of the earth field is fed into the evaluation circuit (11) as a calibration dimension (E), subsequently the inclination angle (.psi.) of the vehicle is established cyclically by means of an inclination measuring device (12) and then the corrected driving direction (.theta.) is established from the computed driving direction (.theta.') as well as from the calibration dimension (E) and the angle of inclination (.psi.) in accordance with the equation .theta.=f (.theta.',.psi.,E). This corrected driving direction can then be further processed or issued to an indicator (13) (FIG. 1).
