摘要:
A deformable subassembly (1) for mounting of headlight in the region of a recess (5) in a wing (4) of a motor vehicle has a sealing channel body (6) connected to the wing (4) in the region of a joint with a motor vehicle bonnet. A headlight cup (3) for mounting the headlight is connected on one side to the sealing channel body (6) spaced from the wing (4). A lower side of the headlight cup (3) is connected to a bracket body (7) that is connected to a supporting structure (8) of the motor vehicle. The sealing channel body (6), headlight cup (3) and/or the bracket body (7) are configured to deform in the event of an impact with a pedestrian so that the risk of injury to the pedestrian is reduced.

A radio resource method and apparatus involves allocating transmission channels to and from a node (26) based on the system load requirement. The load requirement is determined from the quality of service requirement which, in turn, is assessed from the data rate, the bit energy to noise power ratio and the signal classification produced by a converter and sorter (38) in response to signal transmission requests. A maximum load generator (40) delivers the maximum load from these parameters. A core calculator and assignor (42) performs a predetermined algorithm on the outputs of the converter and sorter (38) and the maximum load generator (40) and in response thereto controls a channel selector (30) which selects the channels to and from node (26).
摘要:
The interference on the available communication frequencies is measured during an idle time slot over a first period of time at a first rate. The available frequencies are prioritized based on the interference measurements, and a list is formed of the frequencies having the lowest interference measurements. Interference measurements are made at a second rate, greater than the first rate, for a second period of time less than the first period. When a call is assigned, the interference level requirements for the call are given, and the carrier power level of the call is measured. The carrier-to-interference ratio of each frequency in the list is determined using the second interference measurements and the measured carrier power. The frequencies in the list meeting the interference level requirements for the call are then selected, and frequency hopping while serving the call is performed using the selected frequencies.
摘要:
A method for controlling an electric drive motor (10) of a motor vehicle adjusting drive by means of applying a variable voltage to it should be improved so that an EMV interference suppression can be inexpensively executed. To this end, a controllable resistor (12, 18, 20, 22) is used, which supplies the voltage applied to the drive motor (10).
摘要:
An electronic control device for an electric motor (10), particularly an electrically commutated (EC) motor, whose motor windings (11 to 13), in order to control the winding current, are connected in series with respective control transistors (15 to 17) whose control connections are charged by control pulses which are triggered by commutation signals and which have a predeterminable pulse-duty factor (block control). At the same time, the control device varies the amplitudes of the control pulses to control and permit the operation of the control transistors (15 to 17) in their amplifying range (linear control). Block control dominates in the upper rpm range in order to improve efficiency with respect to pure linear control, and linear control dominates in the lower rpm range in order to prevent severe current peaks, and hence an increased noise development that would occur with pure block control.
摘要:
A forward structure of a motor vehicle, particularly of a passenger car, includes a bumper cross member and an energy absorption element, particularly a foam-type impact absorbing element, disposed in front of the bumper cross member in the driving direction. A plurality of recesses are shaped into the forward-side outer contour of the energy absorption element. To ensure optimal energy reduction while the mounting space is reduced, and thereby a best-possible protective function with respect to a leg impact, at least several of the recesses completely penetrate the energy absorption element along its entire depth, whereby a plurality of breakthroughs are arranged in the energy absorption element.
摘要:
A fender configuration for a motor vehicle has a fender and a deformation element which is C-shaped in cross section. For the substantially vertically oriented supporting of an upper edge of the fender, an upper limb of the deformation element is connected to the fender and a lower limb is connected to the vehicle body. It is important that the C-shaped deformation element is arranged such that it is open toward the associated fender.

摘要:
A method for detecting faulty switching operations of a first relay whose switching element is connected in series with a load and which, depending on the switch position, interrupts or closes the connection to the load in accordance with switching commands. In this context, a current is detected flowing through a circuit containing the switching element, and a faulty function of the relay, in particular a sticking of the switching element, is detected if the current intensity does not correspond to the current intensity to be expected in accordance with the selected switching position. Further relays, which can be provided in order to commutate the potentials at the load, can be included in the test. The method makes possible a relay test without moving the actuators, assuming the relays are in order. In addition, this generates a time savings, since not all of the relays have to be triggered for the test.
