Patent DE-4040003-A1 (DE)
Inventor: MILLER HANS-PETER
IPC: B62D5/06
Filed: 1990-12-14
Abstract: In a servo-assisted steering system for vehicles it is proposed to fit an electric control device (12) to which a torque sensor (17') in the steering region supplies at least the torque applied by the driver and, where appropriate, a differential pressure output signal (12C) and which controls an electric motor (11') driving a hydraulic pump (13').

Inventor: LEHMANN EBERHARD
IPC: H01F5/04
Filed: 1991-05-03
Abstract: The proposal is for the production of a coil former with ends (5) injection moulded in a lower flange (2') for the through connection of suitable terminal pins (3) which can be wound in a section (4) beneath the lower flange (2') with ends of coil windings, in which the terminal pins (3) are flattened beneath the section (4) into a rectangular cross-section (S3) and bent in the region of the flattened section (S3) to form surface-mountable connectors (1).

The estimates of the channel parameters are carried out at different time points within the time duration of a preamble. Pref. the time interval of the different time points is smaller the a period of length of the periodically carried out test sequences. USE/ADVANTAGE - For short wave connections etc., with facility for sufficiently precise Doppler frequency estimate.

Filed: 1991-10-04
Abstract: A drive system for a motor vehicle having at least one driven wheel (1, 7) on each side of the longidudinal axis of the vehicle comprises an internal combustion engine (13), an electric generator (11) driven by the internal combustion engine (13), an electric motor (9) for each driven wheel (1, 7) and an electronic control system (15, 19, 21) that controls the amount of electric power supplied by the generator (11) to the individual electric motors (9). The control system (15, 19, 21) controls the power and the distribution of the driving torques to the individual wheels (1, 7) so that the roll steer effect of the vehicle is controlled by conferring a yawing moment that depends for example on the transverse acceleration of the vehicle or on the extent of a yawing moment generated by a side wind. By measuring the wheel pressure of the individual driven wheels, the road grip limits of the wheels may be detected and the electric motors may be controlled in order to improve traction.
