  • Patent number: 7856858
    Abstract: A steering lock for locking the steering spindle of a motor vehicle steering system including a blocking element that pivots along a longitudinal axis from a locking to an unlocking position using an electromechanical drive and is maintained in the unlocking position by a spring-loaded lever. In order to enable the lever to maintain the blocking element in the unlocking position when a worm drive generates the displacement of the blocking element, a worm gear representing a first control contour is used. A first cam for pivoting the blocking element to the unlocking position and a second cam for actuating the lever are mounted on the worm gear. Prior to the pivoting of the blocking element from the unlocking to the locking position, the lever is pivoted from a rest into a release position and, only afterwards, the worm gear enables the blocking element to pivot to the locking position.

  • Patent number: 7857362
    Abstract: A lock for an opening panel. The lock includes a rotary bolt with first and second locking notches, a strike which can be engaged in the bolt in order to lock the opening panel, a retaining pawl including at least one tooth which co-operates with the locking notches of the bolt in order to lock same in relation to the first or second locking notch, and a switch which is controlled with a control lever. The switch has two states which indicate if the lock is open or closed. In addition, the switch includes a mechanical element which co-operates with the control lever when the lock is closed, such that the switch indicates that the lock is closed only when the tooth of the retaining pawl co-operates with the second locking notch of the bolt. The mechanical element includes a pawl which maintains the control lever in position, thereby preventing the switch from changing from the first state to the second state.

  • Publication number: 20100295300
    Abstract: The invention relates to a method for controlling a reversible electrical machine (14) coupled to a heat engine (13). The electrical machine comprises a field winding (18) which is fed by an excitation current and an armature comprising a plurality of phase windings (22) fed by phase currents. According to the invention, the excitation current of the electrical machine is controlled according to the instantaneous rotational speed of the machine and the torque of the heat engine. According to other characteristics, the excitation current is equal to a pre-determined nominal current when the torque of the engine is resistant and the instantaneous speed is slower than a first pre-determined rotational speed, and is weaker than the nominal current when the torque of the engine is driving or the instantaneous speed is faster than the first speed.
