摘要： In a radar apparatus, a laser light generating device generates a laser light. An optical device reflects the laser light to output it in a predetermined direction. The optical device has at least two reflective surfaces with different reflectance to the laser light. A reflected light detecting device detects a reflected light when the laser light is reflected by an object. An object detecting device detects the object based on the reflected light. An intensity changing device changes an intensity of the outputted laser light by switching the reflective surfaces. Thus, it can be prevented that an intensity of the reflected light becomes too large and an accuracy of detection of the object can be improved.

摘要： A polygon mirror of an object detector of a vehicle includes first faces for projecting a laser to a first predetermined area and a second face for projecting the laser to a second predetermined area higher than the first predetermined area. The polygon mirror is rotated to project the laser to the first and second predetermined areas through a projection window. Thus, the laser can be projected not only to an area at normal height in front of the vehicle but also to an area higher than the normal height in front of the vehicle. Thus, even if a reflection object of an obstacle is positioned at a high position, probe light can be projected to the reflection object. As a result, object detection or distance measurement can be performed correctly.

摘要： A casing is provided for a reflection measurement device emitting a scanning beam and receiving an echo beam caused by reflection of the scanning beam at an object, and detecting a distance to the object in response to the received echo beam. The casing has a window for conducting a beam, and a protective member being transparent to the beam and covering the window from an inside. A predetermined range through which the beam passes is provided in the window. An interval between a lower edge of the beam pass range and a lower edge of the window is greater than an interval between opposing edges of the beam pass range and the window which differ from the lower edges thereof.

摘要： An operation control map of a white line detection apparatus, including a white line detection portion that detects a white line on a road based on a captured image of the road surface, that references the operation control map to determine whether to allow operation of the white line detection portion. The operation control map includes a region in which operation of the white line detection is allowed, and a region in which operation is not allowed, based on the gain of a road surface image signal and the temperature of a road surface imaging portion. The allowed region is set if the reduced accuracy of white line detection, due to the thermal noise generated in the solid-state imaging sensor, falls within an acceptable range, and the disallowed region is set if the reduced accuracy of white line detection falls outside of the acceptable range.

摘要： An object detection apparatus for a vehicle includes a light emitter covered with an emission window, a light receptor covered with a reception window, a defect detection light emitter, a defect detection light receptor and a fracture detection circuit. The light emitter emits a light in front of the vehicle. The light receptor receives the light reflected by an object. The defect detection light emitter emits a detection light into one side of at least one of the emission and reception windows. The defect detection light receptor receives the detection light transmitted through the at least on emission and reception windows at another side. The fracture detection circuit determines whether either of the emission and reception windows are fractured based on the detection light received by the defect detection light receptors.

摘要： A heads-up display unit provided with a display device serving as display image forming means which displays a display image. A hologram serves as a reflecting means, and reflects the display light emitted from the display device, causing reflection of the display image on the interior surface of a vehicle's windshield. A display image is formed outside the windshield towards the front of the vehicle. A concave mirror having a different focal length in different directions is recorded in the hologram serving as a reflecting means so as to offset distortion of the display image caused by curvatures of the windshield. This construction makes it possible to cause the windshield to display a display image free from distortion.

摘要： First, it is determined that a measurable distance of a laser radar device is a first threshold value being an extremely short measurable distance or below, because of dirt on a sensor or bad weather. A vehicle control using measured data of the device is thereby prohibited. Second, it is determined that the measurable distance is a second threshold value being a short measurable distance or below but greater than the first threshold value, because of dirt on a sensor or bad weather. A vehicle speed for allowing the vehicle control using the measured data of the device is restricted. Eventually, the vehicle control is executed under these individual conditions.
