SYSTEM AND METHOD FOR COMBINED BLIND SPOT DETECTION AND REAR CROSSING PATH COLLISION WARNING
First Claim
Patent Images
1. A blind spot detection and rear crossing path warning system for a host vehicle, comprising:
- at least one radar sensor mounted in a rear portion of said host vehicle;
each said radar sensor projecting at least a radar beam and transmitting radar data to an electronic control unit (ECU) with memory;
each said radar beam capable of multiple data transmission to said ECU and having a programmable range limit as determined by said ECU for determining at least one of distance, speed and trajectory of an approaching object to warn an operator when an object is detected within said programmable range limit;
said system operating in a blind spot detection mode when said vehicle is in a forward gear and operating in a rear crossing path warning mode when said vehicle is in reverse gear.

Abstract
A vehicle is equipped with blind spot detection and rear crossing path collision warning system. Programmable maximum range limit radar sensors mounted on the vehicle are used to provide blind spot object detection warning when the vehicle is traveling in a forward direction and rear crossing path collision warning when the vehicle is traveling in a rearward direction.

6. A method for a blind spot detection and rear crossing path warning system, in a host vehicle comprising:
-
monitoring at least one host vehicle blind spot detection and rear crossing path warning radar sensor diagnostics; determining whether said host vehicle blind spot detection and rear crossing path warning radar sensors are within operational specifications; determining whether said host vehicle is in reverse gear; determining said host vehicle state, reversing speed and vehicle trajectory; detecting objects in crossing path detection zones on at least one side of said host vehicle; determining at least one of distance, speed, direction, time in zone of at least one target object in said rear crossing path zone; classifying objects detected in said zone into threatening and non-threatening objects; determining whether any threatening objects are in said rear crossing path zone; determining a collision threat and estimating a severity of collision threat; and providing appropriate warning to an operator of said host vehicle of an impending threat event. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
