摘要： This invention relates to an object recognition apparatus. This apparatus comprises an antenna which emits transmission beams toward a plurality of directions; a receiving circuit which receives reflected signals of the transmission beams from predetermined directions; a distance and direction calculation circuit which calculates distance and direction to objects reflecting the transmission beams based on the transmission beams and the reflected signals; an object pattern storage unit which stores range direction patterns of reflected signals obtained in advance with respect to predetermined objects; an object recognition circuit which compares range direction patterns of the reflected signals received by the receiving circuit with respect to the predetermined directions, with the range direction patterns stored in the object pattern storage unit, and which recognize that a pair of reflected signals from two neighboring directions are signals reflected by the same object.

摘要： A stop determination for a vehicle is provided by requiring simultaneous stop determinations by at least one wheel speed sensor providing output pulses at a rate inversely proportional to vehicle speed and a forward looking radar unit for sensing an object in the vehicle's path and providing a range rate signal with respect to that object. The determination is particularly useful when the time between consecutive pulses at a predetermined minimum speed indicative of an essentially stopped vehicle is greater than a predetermined maximum time period allowed for the determination. Each of the signals complements the other to provide a vehicle stopped determination that is more reliable than either can provide by itself and is workable for most purposes, including stop and go vehicle speed control.

摘要： A radar field-of-view enhancement method particularly adapted for vehicle radar detection systems having a specified detection zone. In accordance with the invention, a pair of discrete radar beams are employed having differing arc widths. Return signals from the discrete beams are compared and related to the area of a desired detection zone. This approach increases the reliability of detection in the detection zone while minimizing false alarms and missed detection areas. The beams are alternately switched on using discrete sources or by implementing a discrete phase shifting element interposed between the sources.

摘要： The present invention provides systems and methods for measuring the likelihood that detected stationary objects are not normally present at a sensed location. Such systems and methods may be used by other systems to which information from the present invention are communicated, for minimizing nuisance alerts in onboard object detection systems such as collision warning, collision avoidance, and/or adaptive cruise control systems. The system includes at least one vehicle mounted sensor capable of sensing at least a target object and providing data related to the target object. The system also comprises a locating device which is capable of determining and providing data related to the location of the machine or vehicle and a processing unit which receives the data from the sensor and the data from the locating device. The processing unit is configured to determine a probability estimate or measure of likelihood that the target object is not a normally present object based upon a comparison to previously recorded data from a reference storage device. The reference storage device stores the previously recorded data acquired from at least one similar sensor and a vehicle locating device while operating in the same geographic area, or stores data derived from such previously recorded data. The invention may enhance vehicle collision warning, collision avoidance and/or adaptive cruise control systems as examples.

摘要： A device for changing the divergence of a beam of microwave radiation comprises a ferrite body having an aperture through which the beam passes. Magnetic wires pass both through the body and across the aperture, or a magnetic coil on either side of the aperture, causes a differential phase delay as the beam passes through the aperture which broadens or narrows the beam.

摘要： A device for increasing the dynamic range of frequency-modulated continuous-wave radar includes a transmitter, a send/receive antenna, a receiver circuit and a circulator. The circulator relays the transmission signals of the transmitter to the send/receive antenna and sends the echo signals of a target object to the input of the receiver circuit, which generates on the basis of the transmission signals and echo signals an intermediate frequency signal having a differential frequency corresponding to the distance from the target object. A reflected power canceler circuit equipped with a control amplifier is provided between the input and output of the receiver circuit. The frequency response of the control amplifier is selected so that the degree of suppression drops to a predeterminable extent with an increase in differential frequency above the cut-off frequency of the control amplifier.

摘要： A preceding-vehicle follow-up control system is arranged to calculate a target vehicle speed based on a vehicle-to-vehicle distance and a controlled-vehicle speed, to calculate a target acceleration based on the target vehicle speed and to control driving force and braking force of the controlled vehicle based on the target acceleration. During this control period, the target acceleration is limited by an acceleration limit and a deceleration limit which are varied according the controlled-vehicle speed, respectively. This arrangement enables a follow-up vehicle speed control to be preferably executed without applying a strange feeling to a driver.

摘要： A preceding-vehicle follow-up control system is arranged to calculate a target vehicle speed employed for bringing a detected vehicle-to-vehicle distance closer to a target vehicle-to-distance, to control the controlled-vehicle speed to bring a controlled-vehicle speed closer to the target vehicle speed, to decelerate the controlled-vehicle speed to a set vehicle speed at a rate of a preset deceleration when the controlled-vehicle speed is greater than a control continuation decision value greater than an upper limit of the set vehicle speed and when the accelerating operation is terminated. This arrangement provides a smooth drive feeing to a driver even after an acceleration of the controlled vehicle is executed during a follow-up control and is terminated.
