摘要： The control precision of when a vehicle is controlled on the basis of the results of sensing by means of a camera (1) and a radar (4) is improved. A vehicle measurement controller mounted in a vehicle comprises image processing means (2) for imaging the surroundings of the vehicle and processing an image signal, radar signal processing means (5) for transmitting a radio wave or light to objects surrounding the vehicle and processing a received signal, and control means (8) for controlling a brake, a throttle, or a transmission on the basis of the results of the outputs from the image processing means (2) and from the radar signal processing means (5). The information outputted from the image processing means (2) and the information from the radar signal processing means (5) each includes time information about the imaging time when the imaging is carried out and measurement time when the measurement is carried out so as to adjust the order of the imaging time and the measurement time. In such a way, even if the processing time of when the imaging and measurement object is simple is different from that of when the object is complex, the imaging time and the measurement time are determined. Therefore, a processing appropriate for the imaging and measurement times is carried out, thereby controlling precisely the travel of the vehicle.

摘要： From a transmitter (18) and a transmission antenna (10), a first frequency signal of a constant first frequency is transmitted for more than a predetermined time, a second frequency signal of a second frequency different by a certain value from the first frequency is transmitted for more than a predetermined time, and a third frequency signal of a third frequency different from the first frequency by twice the certain value is transmitted for more than a predetermined time. Signals of the transmission frequencies reflected from measurement objects are fed to a receiving antenna (11), a mixer (12), an analog circuit section (13), an A/D converter (14), an FFT (15), and a signal processing section (16). The Doppler frequencies of the reflected waves are determined, and the objects are separately detected for every Doppler frequency. Based on the information on the phase and amplitude of the received signal of each transmission frequency, the objects of the same Doppler frequency are separated and identified. In such a way, even when measurement objects moving at substantially the same relative speed are present, they can be separately detected.

摘要： A radar apparatus mounted on a moving object moving along a continuous plane comprises 1 a transceiver unit for transmitting a signal having a main lobe in the moving direction of the moving object and a side lobe directed toward the continuous plane and for receiving a first reflection signal from a target in the main lobe direction and a second reflection signal from the continuous plane in the side lobe direction and 2 control processing means for detecting the frequency of a beat signal of the second reflection signal received by the transceiver unit and the signal emitted by the transceiver unit and for detecting information correlated to the posture of the radar apparatus with respect to the continuous plane on the basis of the frequency. As a result, the variation in the posture of the mounted radar device with respect to the moving object can be detected without adding any hardware.

摘要： A running controller for automobile which can control the acceleration and deceleration of its own automobile, without giving any feeling of physical disorder to the driver of the automobile when the driver drives the automobile in line with preceding vehicles. The controller stores the travelling data at the entry of a curved passage of the preceding vehicle and the distance to the preceding vehicle in advance when its own automobile follows the preceding vehicle and controls the speed of its own automobile, so that the speed can be decelerated slower than the stored data of the preceding vehicle when its own automobile reaches the starting point of the curve.
