    摘要： An object detection apparatus acquires a first position based on a detection result of an object ahead of an own vehicle detected by an electromagnetic wave sensor and a second position based on a detection result of the object detected by an image sensor. When determined that the objects are a same object, the object detection apparatus corrects either of the first position and the second position such that the first position and the second position are positions of the object detected at a same time, based on a time difference between a first amount of time required for the electromagnetic wave sensor to detect the object and a second amount of time required for the image sensor to detect the object. Position information of the object is calculated using the first position and the corrected second position, or the second position and the corrected first position.

    摘要： A method of detecting direction errors of an object, applied to an in-vehicle radar apparatus, whereby in a first step, relative speeds of an object reflecting a continuous wave are obtained by executing frequency analysis of signals acquired by transmitting and receiving the continuous wave. In a second step estimated directions, which are values of estimated directions in which the object is present, are calculated for each of respective frequency bins in which the presence of the object has been confirmed by the frequency analysis executed in the first step. In a third step a theoretical curve is calculated which expresses a relationship between relative speed of a stationary object and directions in which the stationary object is present, with respect to the own vehicle. In a fourth step, the direction errors are obtained as errors of the estimated directions with respect to the theoretical curve.

    摘要： A first specifying-means specifies a first-region including a first detection-point, which is of a first-target on an X-Y plane on which a width direction of a vehicle is defined as an X-axis, and a longitudinal direction of the vehicle is defined as a Y-axis. A second specifying-means specifies a second-region including a second detection-point, which is of a second-target on the X-Y plane, based on a direction of the second detection-point and a target-width, which is a width along the X-axis of the second-target. A determination means determines that the first- and second-targets are the same, provided that an overlapping portion exists therebetween. An estimation means estimates a true-value target-width, based on the direction of the second detection-point and the first detection-point, provided that the first- and second-targets are the same. A correction-means corrects a position of the second-region specified next time by using the true-value target-width as the target-width.

    摘要： A method and system for aligning a sensor of a radar unit mounted on a vehicle, including calculating at least one alignment measurement of the vehicle from a plurality of optical sensors, positioning a target at a predetermined distance forward of the radar unit and determining a position of the radar unit based on the alignment measurement and the predetermined distance of the target. The method further includes transmitting a beam extending forward from the radar unit and positioning the target and the sensor in alignment with an axis of the beam.

    摘要： A method and apparatus for utilizing a vehicle wheel alignment system to guide the placement and orientation of a vehicle service apparatus or alignment fixture relative to the thrust line of a vehicle. A laser adapter for projecting a reference line is mounted to a steerable wheel of the vehicle, and is aligned relative to both a line of the vehicle and to the supporting surface on which the vehicle is disposed. The vehicle line is determined by the vehicle wheel alignment system, and the steerable wheel, together with the adapter, are steered relative to the determined vehicle line, such that a projected reference line defined by the position and orientation of the adapter is established parallel to both the supporting surface and the vehicle line. The placement and orientation of the vehicle service apparatus or alignment fixture is subsequently adjusted relative to the projected reference line.
