Abstract: A radar sensor and a radar antenna are for monitoring the environment of a motor vehicle. A compact construction is achieved by the planar array of both the control circuit and the radar antenna, so that the radar sensor may be located, for example, in the area of a motor-vehicle bumper. Example configurations consist of the separate line support for arranging lines to transmit high-frequency signals between the control circuit and the radar antenna and the configuration of the radar antenna as a Rotman lens, in relation to the signal propagation times and the layered arrangement of Rotman lens and group antenna.

Abstract: The present invention relates to a CW radar method for measuring distances between and relative speeds of a vehicle and one or more obstacles. The present invention further provides that the transmission (s(t)) can be composed of at least four consecutive chirps (A, B, C, D), each having different slopes. The intersection points of all lines in the distance-relative speed diagram from two chirps (A, B) can be calculated from all the ascertained frequency positions K1,n and K2,p. To validate those intersection points, one may observe whether a peak exists in the Fourier spectrum of a third chirp C at a frequency position K3,q, whose assigned line intersects a surrounding area of the intersection point in the distance-relative speed diagram.

Abstract: An arrangement for steering a motor vehicle having at least two steerable wheels including steering equipment for setting the position of the steerable wheels as a function of a desired steering angle signal and braking equipment which is present in the vehicle and which, in the event of a fault in the steering equipment, produces selectively different braking forces at the wheels as a function of the desired steering signal. A method for steering a motor vehicle in the event of failure of the steering equipment includes the step of applying different braking forces to the vehicle wheels in accordance with a desired steering angle signal.

Abstract: A method and arrangement for emergency braking of a vehicle includes a detection system on the vehicle which detects obstacles located in or near the direction of motion of the vehicle and generates corresponding data, sensors on the vehicle which generate data representing characteristic parameters of the condition of the vehicle, and an evaluating unit which determines, from the data on the obstacles and the parameters of the condition of the vehicle, target values for controlling the motion of the vehicle and, only upon determining that an impending collision of the vehicle with an obstacle is no longer avoidable by any action on the vehicle by steering or braking, triggers an automatic emergency braking for rapid deceleration of the vehicle.

Abstract: An arrangement for determining the distance of objects has a number of electrostatic ultrasonic transducers which are formed from superposed layers. Fixed electrodes for the transducers and conductive tracks connected to them are formed in a first structured metal layer. The other layers are an insulation layer and a full-surface second metal layer on the insulation layer which provides counterelectrodes for the electrodes provided by the first metal layer.

Abstract: A vehicle radar emits four groups of single-frequency stepped radar pulses. In group A, the frequency of each pulse is a fixed amount higher than that of the preceding pulse. In group B, the frequency of each pulse is a fixed amount lower than that of the preceding pulse. In group C, the frequency of each pulse is the same as that of the preceding pulse. In group D, the frequency of each pulse depends on a modulo algorithm. The signals reflected from other vehicles may readily be processed with inexpensive equipment to discriminate among such other vehicles, and to determine the distance to, and relative speed of, each such vehicle.

Abstract: In the particular embodiment disclosed in the specification, a CW radar process for measurement of distances and relative speeds between a vehicle and one or more obstructions including transmitting a sequence of constant-frequency radar signal bursts which follow one another without any time interval during four successive measurements. In the first measurement, the radar signal bursts are of sequentially increasing frequency and in the second measurement they are of sequentially decreasing frequency while in the third measurement they have the same frequency and in the fourth measurement the burst frequencies follow a coded pattern. Demodulation of the signals which are reflected by obstructions is carried out by mixing them with the transmitted signals using only one single-channel mixer providing an output signal which is not the signal of a phase curve but of an amplitude curve.

Abstract: Contactless measurement of the distance traveled by a vehicle during selected time intervals is provided by a device operating on the Doppler principle. The device has a "phase-locked loop" circuit which generates pulse signals having a frequency proportional to the vehicle velocity. Using the pulses as path length increases, the pulses are added in a counter and the counter output is supplied to an indicating unit to indicate the distance traveled by the vehicle.

Abstract: The invention concerns a method for propulsion regulation of an automobile in the sense of prevention of undesirable spinning of the driven vehicle wheels whereby, as needed, only one of the wheel brakes is activated or the engine torque is reduced. Thereby is determined in the manner of an adaptive regulation in constant repetition from measured rotational speeds and stored vehicle and engine parameters for each driven wheel according to the relation M.sub.u =.theta.*..DELTA..omega., the excess moment causing the spinning of the wheel concerned and subsequently for each of the driven wheels in accordance with the relation M.sub.red =M.sub.u +k(.DELTA..omega.-s) the reduction moment required to eliminate the spinning/tendency to spin, which reduction moment is caused to be applied, depending on each driving situation, either in form of a brake torque in the correct magnitude and/or in form of a reduction of the engine torque in the correct magnitude.
