Document Type and Number:
Japanese Patent JP2991659
Kind Code:
B2
Abstract:
A rear and side object detection system for a vehicle (10) based on monolithic millimeter wave integrated circuit technology. A multiple antenna configuration is employed that defines six sensing regions (130,132,134,136,138,140) to the right, left and the rear of the vehicle. A first sensing region (140) is defined at the right side (20) of the vehicle (10), a second sensing region (132) is defined at the right side (20) and rear (22) of the vehicle (10) and overlaps the first sensing region, a third sensing region (136) and a fourth sensing region (130) extend from the rear (22) on both sides (18,20) of the vehicle (10) in the adjacent lanes, a fifth sensing region (134) is defined at the left side (18) of the vehicle and a sixth sensing region (138) is defined at the left side (18) and rear (22) of the vehicle (10) and overlaps the second (132) and fifth (134) sensing regions. A right side warning signal is issued if an object is detected in a right side detection zone defined by the first sensing region or a portion of the second sensing region that does not overlap the third or sixth sensing regions. Likewise, a left side warning signal is issued if an object is detected in a left side detection zone defined by the fifth region and a portion of the sixth sensing region that does not overlap the second or fourth sensing regions. A back-up warning signal is issued if an object is detected in an overlap region (146) between the second (132) and sixth (138) sensing regions.
