DRIVER ASSISTANCE SYSTEM INCLUDING WARNING SENSING BY VEHICLE SENSOR MOUNTED ON OPPOSITE VEHICLE SIDE
First Claim
1. An assistance system for providing an approaching vehicle warning for a host vehicle, the system comprising:
- A first rear sensor unit positionable proximate to a rear corner of the host vehicle, the first rear sensor unit including an electronic control unit and a sensor, the electronic control unit configured to;
obtain host vehicle driving path information;
determine, from the driving path information, an area corresponding to an immediately adjacent lane extending rearwardly from a left side of the host vehicle and an area corresponding to an immediately adjacent lane extending rearwardly from the right side of the host vehicle;
detect a closing object in the immediately adjacent lane extending rearwardly from a side of the host vehicle closest to the rear sensor unit and, in response to detecting the closing object, provide a near-lane warning signal; and
detect a closing object in the immediately adjacent lane extending rearwardly from a side of the host vehicle opposite the rear sensor unit and, in response to detecting the closing object, providing an opposite-lane warning signal to a second rear sensor unit positionable proximate to a rear corner of the host vehicle opposite the first rear sensor unit.

Abstract
A driver assistance system senses and provides an indication of an approaching vehicle located sidewardly and rearwardly within an immediately adjacent driving lane to a host vehicle. The system includes left and right rear sensor units proximate rear corners of the host vehicle. The rear sensor units sense vehicles on respective sides and rearwardly of the host vehicle. When either rear sensor unit detects an approaching vehicle within the adjacent lane on the opposite side of the host vehicle therefrom, the rear sensor unit provides an opposite-lane warning signal to the other rear sensor unit. The system includes providing host vehicle driving path information to the rear sensor units for determining the path of the adjacent lanes adjacent to and rearward of the host vehicle. The path information accounts for curves in a roadway. Further, the rear sensor units detect the speed of a closing vehicle. When a left rear sensor unit senses a closing vehicle in the immediately adjacent left lane or obtains an opposite-lane warning signal from a right rear sensor unit, the left rear sensor unit provides a warning signal to an alarm unit for a vehicle approaching in the left lane. When the right rear sensor unit senses a closing vehicle in the immediately adjacent right lane, or receives an opposite-lane warning signal from the left rear sensor unit, the right rear sensor unit provides a warning signal to the alarm unit.

8. A method of determining when a closing object in an adjacent lane is approaching a host vehicle, the method comprising:
-
obtaining, by an electronic control unit, host vehicle driving path information; determining from the driving path information, locations of immediately adjacent lanes to a left side, a right side and extending rearwardly of the host vehicle; detecting, by a first rear sensor unit positioned proximate to a rear corner of the host vehicle, a closing object in the immediately adjacent lane on a side of the host vehicle closest to the first rear sensor unit and providing a near-lane warning signal; and detecting, by the first rear sensor unit, a closing object in the immediately adjacent lane on a side of the host vehicle opposite the first rear sensor unit and providing an opposite-lane warning signal to a second rear sensor unit positioned proximate to a rear corner of the host vehicle opposite the first rear sensor unit. - View Dependent Claims (9, 10, 11)

12. A driver assistance system for providing a closing object warning for a host vehicle, the system comprising:
-
a right rear sensor unit configured for positioning proximate a right rear corner of the host vehicle, the right rear sensor unit including a right electronic control unit and a right sensor; a left rear sensor unit configured for positioning proximate a left rear corner of the host vehicle, the left rear sensor unit including a left electronic control unit and a left sensor, the left electronic control unit configured to; obtain host vehicle driving path information; determine, from the driving path information, an area corresponding to an immediately adjacent lane extending rearwardly from a left side of the host vehicle and an area corresponding to an immediately adjacent lane extending rearwardly from the right side of the host vehicle; detect distance and speed of objects located rearwardly, leftwardly and rightwardly of the host vehicle with the left sensor; determine a closing object in the adjacent left lane and providing a left lane warning signal; and determine a closing object in the adjacent right lane and providing an opposite-lane warning signal to the right rear sensor unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
