摘要:
A device for testing a safety and/or driver assistance system of a first vehicle with the participation of at least one second vehicle in the region of a fixedly predefined roadway section in particular in the region of an intersection, wherein the first vehicle and the at least one second vehicle comprise in each case at least one transmitter and/or at least one receiver for the C2X communication in connection with the safety and/or driver assistance system. In order to prevent or to keep to a minimum damages to vehicles and/or injury to persons, the second vehicle is represented by a dummy device that moves in the region of the roadway section, the dummy device having the largest portion of its volume and/or its mass outside the movement of the first vehicle.
摘要:
Tire module for the detection of tire state quantities which includes a printed circuit board and a piezoelectric transducer with a housing and at least one transducer element, wherein the transducer element is coupled to piezoelectric material or consists of piezoelectric material, and wherein the piezoelectric transducer is executed as a surface-mounted device (SMD) and as such is mounted on the printed circuit board by terminal areas and is electrically connected to the printed circuit board.
摘要:
A vehicle key for radio communication with a vehicle. The vehicle key has a radio transmitter for transmitting radio signals to the vehicle. The vehicle key has a radio receiver and/or audio receiver to be able to locate the vehicle within close range. A bidirectional communication with a transceiver of the vehicle is set up by the radio receiver and/or the audio receiver and the radio transmitter. Furthermore, a corresponding method for locating the vehicle by using the vehicle key is described.
摘要:
According to one exemplary embodiment of the invention, a vehicle antenna apparatus is provided on a vehicle in such a way that this results in the antenna having a horizontal main beam direction. A first reflection apparatus above the conductive roof of the vehicle, with an exciter between these two elements, causes the reflections to be doubled, thus causing the main beam direction to be lowered from a vertical to a horizontal direction.

A method for transmitting travel route information to a person present outside of a motor vehicle, and to a system for transmitting such information. The method for transmitting travel route information to a person present outside of a motor vehicle provides that a navigation system present in the motor vehicle wirelessly transmits a data stream including the information to be transmitted directly or indirectly to a display device carried by the person. The information to be transmitted can be perceived by the person by the display device.
摘要:
The present invention relates to a method for the sensorless electric measurement of the position of a rotor of a permanently excited synchronous machine that is fed by a converter, by means of measuring signals which are sent to an evaluation device that calculates the electric position of the rotor from the angular dependence of the current space vector at an impressed stator flux pattern, wherein the distribution of absolute values of the differential current space vector varies in approximation in sinusoidal manner with twice the value of the electric rotor position angle sought. The method of the invention which can be used in particular in stationary or blocked machines is characterized in that the distribution of absolute values is produced from respectively two successive measurements for an almost inversed magnetization, in such a way that the superposition of the impressed stator flux and permanently excited rotor flux enables, due to saturation, a distribution of absolute values of the current space vector with two different maximum values, from which the electric rotor position angle sought is determined directly and unambiguously over 360°.

摘要:
The invention relates to a method and a correspondingly arranged communication device for channel estimation in vehicle-to-environment communication, wherein a model of the environment influencing the vehicle-to-environment communication is produced from parameters of a vehicle-to-environment communication and the quality of the model for the environment is ascertained by the convergence of the parameters used in the model. The course of the convergence of the parameters in the model is monitored and conclusions are drawn with regard to the environment from the course of the convergence of the parameters.
