Abstract
Abstract An object detecting system mounted on a conveyance such as a vehicle having a laser radar as an object detector mounted on the vehicle at a position offset from the vehicle longitudinal center line, for adjusting in a factory the radar mounting position in a software manner by utilizing a computer program. A reflective target is placed ahead of the vehicle on the line extending from the vehicle longitudinal center line at a position relatively close to the vehicle in the factory. The central axis of the transmitted beam is first aimed at the target reflector such that the axis is made equal to the direction of the target reflector, and is changed by an angle of offset such that the axis is aligned with an inherently desired direction which is parallel to the vehicle longitudinal center line. With this, the radar mounting position is precisely adjusted to the desired position using a relatively short range (site) for testing and adjustment, in a software manner by utilizing a computer program, improving the efficiency of radar mounting position adjustment operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A system for detecting an object positioned ahead of a conveyance in the forward direction at a position distant from the conveyance, said system comprising: an object detector mounted on a conveyance offset from the longitudinal center line thereof, which transmits a signal in a forward direction to scan in a horizontal direction, perpendicular to the forward direction, within a predetermined range of scanning; reference position setting means for setting a reference position at a line extending to the object; distance determining means for determining a distance to the object based on an output of the object detector; mounting position determining means for determining an offset position of the object detector mounted on the conveyance in the horizontal direction; and correcting means for correcting at least one of the reference position and the predetermined range of scanning based on the detected distance and the determined offset mounting position.
Claim 2
Independent Claim
148 words
A system for detecting an object positioned ahead of a conveyance in the forward direction at a position distant from the conveyance, said system comprising: an object detector mounted on a conveyance offset from the longitudinal center line thereof, which transmits a signal in a forward direction to scan in a horizontal direction, perpendicular to the forward direction, within a predetermined range of scanning; reference position setting means for setting a reference position at a line extending to the object; distance determining means for determining a distance to the object based on an output of the object detector; mounting position determining means for determining an offset position of the object detector mounted on the conveyance in the horizontal direction; and correcting means for correcting at least one of the reference position and the predetermined range of scanning based on the detected distance and the determined offset mounting position.
Claim 3
Dependent Claim
63 words
A system according to claim 1, wherein the object detector transmits a signal in the forward direction and receives a return signal, and the reference position setting means sets the reference position based on a direction of a signal transmitted at a time when the transmitted signal is returned such that the reference position is set at the line extending to the object.
Claim 4
Dependent Claim
71 words
A system according to claim 2, wherein the reference position setting means includes: threshold value setting means for setting a threshold value in an output level of the return signal; and intermediate portion defining means for defining an intermediate portion exceeding the threshold value in the output level of the return signal; and wherein the reference positions setting means determines the time when a point in the intermediate portion is detected.
Claim 5
Dependent Claim
43 words
A system according to claim 2, wherein the reference position setting means includes: peak detecting means for detecting a peak in the output level of the return signal; and wherein the reference positions setting means determines the time when the peak is detected.
Claim 6
Dependent Claim
57 words
A system according to claim 1, wherein the mounting position determining means determines a mounting position of the object detector on the conveyance in the horizontal direction as an offset from a longitudinal center line of conveyance and the correcting means corrects the reference position based on the detected distance and an angle of the determined offset.
Claim 7
Dependent Claim
12 words
A system according to claim 1, wherein the conveyance is a vehicle.
Claim 8
Dependent Claim
20 words
A system according to claim 2, wherein the object detector is a radar and the object is a target reflector.
