    • 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).

    • 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).

    • A magnetometer with a time coding is proposed, which serves to measure magnetic fields in the motor vehicle and in particular to measure the direction of the earth field and to determine the driving direction. The magnetometer includes at least one sensor having a horizontally disposed, magnetizable rod-shaped core and a winding disposed on the core. The winding carries an alternating current for generating an auxiliary alternating field, in order to magnetize the core in alternation up to and into saturation. In order to measure the magnetic field detected by the sensor and to generate the auxiliary alternating current, a controlled alternating current source (18) is connected on the one hand to one and the same winding (19), and on the other hand a measurement voltage that can be picked up at this winding (19) is connected to an evaluation circuit (21, 25, 12, 13). The degree of deviation between the positive and negative half-waves of the measurement voltage represents a measure for the magnitude of the magnetic field measured. The magnetometer is intended for use as part of an electronic compass, preferably for navigational purposes in vehicles.

    • A method is described for determining the wheel speed during braking of a vehicle having in addition to at least one wheel with speed sensor at least one further wheel without speed sensor and means for determining the braking pressure. For this purpose, the braking operation is subdivided into several time intervals during which the relative value from the braking energy and the kinetic energy of the vehicle are obtained, and the contribution of the wheels without speed sensors to the braking energy is defined during a first time interval. Furthermore, the ratio of the relative value in this time interval to the relative values in further time intervals is formed, and the mean value for the wheel speed of all wheels without speed sensors is ascertained in the further time intervals from the ratio of the relative values.
