  • Patent number: 9548579
    Abstract: A method for assembling cables includes sliding a housing and a sleeve accommodated in the housing onto a cable in such a manner that the sleeve surrounds at least a portion of the cable. The housing is made of an electrically non-conductive material, the sleeve is made of an electrically conductive material and includes a cutting edge pointing radially inward, and the cable includes a conducting element and an insulation surrounding the conducting element. The method further includes magnetically forming the sleeve by applying a magnetic field to the sleeve through the housing, such that the sleeve is pressed against the insulation and the cutting edge penetrates the insulation completely and contacts the conducting element.

  • Patent number: 8781667
    Abstract: A method for noise reduction in a motor vehicle that has a hybrid drive and includes an internal combustion engine and at least two electric machines including a first electric machine on a front axle of the motor vehicle and a second electric machine on a rear axle of the motor vehicle. The method includes automatically cutting in the at least two electric machines as a function of a required drive torque and an expected noise emission associated with the required drive torque, in a case of sole operation of the internal combustion engine, so as to reduce the load of the internal combustion engine. Torque distribution is carried out variably between the front axle and rear axle of the motor vehicle.

  • Patent number: 8676424
    Abstract: A drive system includes at least two drive devices, at least one of which is electric, that drive at least two drive axles, a power electronics system, an energy storage arrangement, and a control device. The control device includes a drive control module for providing a recuperation limiting value for each electric drive, a recuperation control module for combining the recuperation limiting values to form a maximum recuperation total limiting value, and a brake control module for providing a total braking torque requested by a driver or assistance system, such that it derives a recuperation total torque that is less than the recuperation total limiting value and also derives recuperation partial torques for each electric drive. In the case of a total braking torque that is greater than the recuperation total limiting value, the brake control module generates a hydraulic brake pressure and transmits it to the brake system.

  • Patent number: 7357676
    Abstract: A fuse holder for use in motor vehicles. The fuse holder comprises an elongated box-shaped housing having flat-fuse type slots accessible from the upper side of the housing and contact chambers arranged beneath the slots within the housing. The chambers can receive the contact feet of single contacts and/or current bridges. Contact chambers of the current bridge and of the single contacts can be substantially identically configured, which may permit a more versatile use. Each contact chamber can be fitted with two mutually facing catch recesses for catch projections of the single contacts. Each contact chamber can also be fitted with at least one catch recess for the current bridge. Moreover, each contact chamber can be fitted with a receiving shaft for two contact feet where the feet are aligned parallel to one another and transverse to the extension direction of the elongated housing.
