摘要： Safety of the distance between vehicles is judged by monitoring whether or not an object other than a front road surface, namely, a preceding vehicle, exists in a predetermined area of the front road surface which is recognized by a picture processing unit used as a sensor for recognizing traffic states of the front road, without recognizing an image of a preceding vehicle having a complicated shape and a plurality of colors of the preceding vehicle by means of picture processing.

摘要： Fixed to a vehicle bumper (2), a radar aerial (3) uses dwarf radio waves. Controlled by a radar signal processing unit (4), an alarm device (5) sets off an alarm whenever there is a dangerous distance between the vehicle and another vehicle traveling ahead. Designed with feeder perforations, a film (6) forms a continuous belt fitted in front of the radar aerial to prevent snow, ice and dust from sticking to the aerial.

摘要： The invention relates to a radar system for controlling a gate power supply and drain power supply of a MMIC (micro wave monolithic IC), protecting the MMIC at the time of start and shut-off, and simultaneously avoiding an occurrence of a failure in the MMIC due to a residual charge and an abnormal supply potential at the time of shut-off. A power supply control means (a timer circuit 510 and 512) controls the gate and drain power supplies (508,507) at the rise time so that an output voltage of the gate power supply (508) rises earlier than that of the drain power supply (507). Another power supply control means (a discharge circuit 509) controls the gate and drain power supplies at the fall time so that an output voltage of the gate power supply (507) falls later than that of the drain power supply (508). Another power supply control means (the drain power source control circuit 511 for RF) turns off the drain power supply (507) of the FET among power supplies when it is detected by a voltage monitoring means (513-516) that even either of output voltages of the power supplies (501,502,505,506, etc.) is not within said specified range.

摘要： The invention relates to a vehicle speed control apparatus for allowing a host vehicle (1) trailing a preceding vehicle (2) to accelerate and decelerate without causing discomfort to the host vehicle driver. While the host vehicle (1) is trailing the preceding vehicle (2), the apparatus on board the host vehicle (1) stores the speed of the preceding vehicle (2) entering a curve ahead as well as a headway distance of the host vehicle (1) to the preceding vehicle (2). Upon reaching the curve, the host vehicle (1) is controlled by the apparatus to enter the curve at a speed not in excess of the stored speed of the preceding vehicle (2).

摘要： PCT No. PCT/JP96/01133 Sec. 371 Date Dec. 24, 1996 Sec. 102(e) Date Dec. 24, 1996 PCT Filed Apr. 25, 1996 PCT Pub. No. WO96/34363 PCT Pub. Date Oct. 31, 1996An image pickup unit (2) mounted on a vehicle shoots an image in front thereof to attain image information. An edge pixel extraction section (40202 to 40206) scans the obtained image information for each line and then checks boundaries between a particular color and the other colors to extract pixels having the particular color as edge pixels. Moreover, a candidate line extraction section (40208 to 40212) references position coordinates of the extracted edge pixels such that assuming the edge pixels to be classified to configure straight lines, the edge pixels are coupled with each other to configure straight lines according to the classification so as to obtain the straight lines as candidate lines. Thereafter, a line selection section (40212) selects a left line and a right line in front of the vehicle from the plural candidate lines, thereby attaining the left and right lines.

摘要： In a method of adjusting the axis of a car on-board radar, especially, a car on-board mono-pulse radar having the function of transmitting radio waves, light or ultrasonic waves, a car axis and an offset axis are set and the mount angle of an antenna offset-mounted on the offset axis can be adjusted with high precision and with ease through a reduced number of process steps. In the method, at least two points are set on the car, at least two isosceles triangles having a common base defined by a line connecting the setting points and sides of different lengths are drawn, a line connecting vertexes on the same plane of the obtained isosceles triangles and an extension of that line are determined as the car axis, the radar antenna is mounted on the car at an offset position which is apart from the car axis by a constant distance in the horizontal direction, a straight line parallel to the car axis and passing through the offset position is determined as the offset axis, a reflector is disposed in a direction at a constant azimuth angle as viewed from the offset position of the antenna, and the reflector is used as a detection target of the radar to adjust the mount angle of the radar antenna such that an azimuth angle detection value of the reflector detected by the radar equals a setting value of the azimuth angle.

摘要： The method involves determining at least two points on the vehicle, forming at least two isosceles triangles with a common base defined by a line through the two points and with sides of different lengths, and defining a line connecting the apices (22,23) and its extension as the vehicle axis (5). A radar antenna is mounted on the vehicle at a point separate from the vehicle axis and a parallel line through this point defined as the offset axis. A reflector is placed at a point at an azimuth angle to the antenna position and used as the radar detection target to set the radar antenna angle so that the detected azimuth angle equals a desired value.
