  • Patent number: 6219604
    Abstract: A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.

  • Patent number: 6202614
    Abstract: The invention relates to a drive assembly of a motor vehicle, having a internal combustion engine and an electrical machine coupled or capable of being coupled to a crankshaft of the engine, wherein the electrical machine can be switched to motor and generator modes, and having an electronic control unit for controlling direct injection and ignition of the engine. It is provided that at the start of the engine (12) the crankshaft (16) can be put in a predeterminable starting position via the electrical machine (22) switched for motor operation, and upon attaining the starting position of the crankshaft (16), the ignition of the fuel injected into a starting cylinder (14) is effected, and via the electrical machine (22), a torque can be exerted on the crankshaft (16) during the entire starting operation.

  • Patent number: 6098584
    Abstract: The starter apparatus for an internal combustion engine (2) includes a starter-generator including a device for rotating a flywheel (5) to a predetermined rotational speed and a device for rotating the crankshaft (3) of the engine to directly start the engine; at least one clutch (6, 7) for directly coupling or disengaging the flywheel (5) with the crankshaft (3) of the engine (2) so that the flywheel (5) starts the engine (2) with the rotational energy stored in the flywheel (5) by the starter-generator in an impulse starting method and a changeover device (11) for changing between the impulse starting method based on engagement of the flywheel (5) with the engine (2) and a direct starting method in which the starter-generator (4) is directly coupled to the engine, wherein the changeover device switches between the direct starting method and the impulse starting method as a function of a temperature of the engine (2) so that the impulse starting method is used at comparatively lower temperatures and the dire

  • Patent number: 5236056
    Abstract: A method for assisting the steering forces to be produced in a vehicle by means of an electric motor acting on the steering column is proposed. This method is characterized in that the additional torque produced by the electric motor is controlled in dependence upon the steering torque to be produced for actuating the steering and upon the steering torque supplied overall. The additional torque is thus dependent on the torque which is produced at the steering wheel by the driver and, in addition, on the torque which is supplied by the steering arrangement on the wheels to be steered. The electric motor is controlled by a controller 5 via an actuator 6, an additional torque M*.sub.R, which is dependent on the vehicle speed, being input into the controller. As characteristic shaper, the controller has a dead-time element by which the control intervenes only from a certain limit value of the torque M*.sub.R input into the controller 5.

  • Patent number: 4614887
    Abstract: To provide a dynamo electric machine, for combination, preferably, with a centrifugal circulating pump, having a rotor which is at least part-spherical, the stator is formed of edge-wound strip material, in which the stator part is a continuous strip of L-shape deformed strip, with notches (9') cut into the L prior to deformation, the bending edge (15) of the L changing throughout the length of the strip, uniformly, with uniform change of the spacing of the notches so that, as the strip is wound over a part-spherical form which defines an air gap between the rotor and stator, the width of the teeth between adjacent notches (9') will increase to define continuous through-slots (9) for the windings, and the bending corner (15) likewise will change from a position near the root of the notches (9') to a position within the solid portion of the second leg (18) of the L.

  • Patent number: 4500772
    Abstract: A combined on-board electric network generator and heater for vehicles, having mounted in its housing an armature which supports at least one alternating current coil and, more particularly, three-phase current coils. The combined generator-heater has a drum-shaped rotor, driven by the engine of the vehicle. The housing of this unit is closed and encloses the rotor as well as the armature and is formed with fluid ducts. Within the housing, a cooling-air circulation is maintained which streams over the coils and rotors and cools them, transferring heat to heat exchange elements which form part of the housing. A cooling fluid circulates in the ducts in a loop through input and output ports. The loop closes upon itself outside of the housing. The cooling fluid circulation recovers heat losses in the generator and makes the heat available for heating the passenger compartment of a vehicle.

  • Patent number: 4484049
    Abstract: An additional claw-pole rotor similar to that of the alternator of a motor vehicle and excited by a similar winding is mounted on the same shaft as the rotor of the alternator and is surrounded by a stator core carrying, instead of winding, a short circuiting ring at each end and having tubular armature rods built into the stator core which run from one short circuiting ring to the other. The short circuiting rings provide channels for a heat transfer liquid that communicate with the inside of the tubular rods so that induction currents in the armature rods will heat the heat transfer liquid that is circulated through the heater of the car. An additional slip ring is necessary for the exciter current of the heat generator which may be varied or regulated to control the amount of heat generated.

  • Patent number: 4421998
    Abstract: To reduce the axial length of an alternator, so that it can be attached, for example, to the end wall (10) of an automotive engine having a stub shaft (11) projecting therefrom, a transmission housing, clutch housing, or the like, a support structure (22, 122) has ring-shaped axially extending portions (23, 45, 145) the outer ones of which retain the armature (12, 13) typically three phase, and the inner one retains the outer races of ball bearings (35, 36; 76a, 135, 136), the inner races of which are secured to axially inwardly extending portions (31, 131) of a claw pole rotor having claw poles rotating within the gap formed by a field structure (20, 120) and the stationary windings so that the ring-shaped axial inner projection (45, 145) of the support structure interengages and overlaps the axially extending inner projection (31, 131) of the claw pole structure, and the ball bearings are placed in essential alignment with the stator core and the field core, and positioned within two parallel planes (37, 38
