System and method for controlling inter-vehicle distance using side and rear sensor
First Claim
1. A system for controlling inter-vehicle distance, comprising:
- a first sensor configured to obtain information relating to a preceding vehicle relative to a subject vehicle;
at least one second sensor configured to obtain information relating to one or more vehicles in right and left lanes relative to the subject vehicle;
an inter-vehicle distance controller configured to determine an avoidance direction for a lane change from data detected by the at least one second sensor when it is determined from data detected by the first sensor that an end collision is unavoidable via only brake input; and
a steering controller configured to receive information relating to the avoidance direction determined by the inter-vehicle distance controlling unit and apply a steering force to a steering device to guide a driver to a lane in the determined avoidance direction.

Abstract
A system and method are provided for controlling inter-vehicle distance. The system includes a front sensor, a side and rear sensor, an inter-vehicle distance controlling unit, and a steering controlling unit. The front sensor obtains information relating to a preceding vehicle. The side and rear sensor obtains information relating to vehicles in right and left lanes. The inter-vehicle distance controlling unit determines an avoidance direction for a lane change from data detected by the side and rear sensor when it is determined from data detected by the front sensor that a front end collision is unavoidable through just brake input. The steering controlling unit receives information relating to the avoidance direction determined by the inter-vehicle distance controlling unit and applies a steering force to a steering device to guide a driver to a lane in the determined avoidance direction.

7. A method for controlling an inter-vehicle distance, comprising:
-
determining, by a processor, whether a front end collision of a subject vehicle is avoidable through just brake input from data detected by a first sensor for obtaining information relating to a preceding vehicle during operation of inter-vehicle distance control; determining, by the processor, an avoidance direction for a lane change of the subject vehicle from data detected by at least one second sensor for obtaining information relating to vehicles in right and left lanes relative to the subject vehicle in response to determining that the front end collision is unavoidable through just brake input; and transmitting, by processor, information relating to the avoidance direction to a steering controller to apply a steering force to a steering device to guide a driver to a lane in the determined avoidance direction. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. The method of clam 7, wherein the processor delivers a both-direction risk signal to the steering controller when determining that both directions are dangerous in the determining of the avoidance direction, to apply a steering reaction force in both right and left directions during the driver'"'"'s steering input to restrain driver'"'"'s steering wheel manipulation.

17. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that determine whether a front end collision of a subject vehicle is avoidable through just brake input from data detected by a first sensor for obtaining information relating to a preceding vehicle during operation of inter-vehicle distance control; program instructions that determine an avoidance direction for a lane change of the subject vehicle from data detected by at least one second sensor for obtaining information relating to vehicles in right and left lanes relative to the subject vehicle in response to determining that the front end collision is unavoidable through just brake input; and program instructions that interpret information relating to the determined avoidance direction and apply a steering force to a steering device to guide a driver to a lane in the determined avoidance direction.
