Lane-changing support system
First Claim
1. A lane-changing support system comprising:
- a host-vehicle driving-state detection section that detects a driving state of a host vehicle;
a peripheral vehicle detection section that detects peripheral vehicles;
a lane detection section that detects a lane marking around the host vehicle; and
a processing unit being configured to receive information from at least the host-vehicle driving-state detection section, the peripheral vehicle detection section, and the lane detection section, for generating support information on lane-changing support;
the processing unit comprising;
(a) an end-of-traffic-merging setting section that sets an assumed traffic-merging end serving as a temporary measure at which a lane change by the host vehicle has to be completed;
(b) a peripheral vehicle behavior prediction section that predicts a driving behavior of each of the peripheral vehicles;
(c) a host-vehicle manipulated variable setting section that generates at least one manipulated-variable time series of a host vehicle'"'"'s manipulated variable to be executed during a time period from a time when a decision that there is a necessity of lane-changing has been made to a time when the host vehicle reaches the assumed traffic-merging end;
(d) a manipulated variable decision section connected to the peripheral vehicle behavior prediction section and the host-vehicle manipulated variable setting section for determining whether the lane change by the host vehicle is appropriately achievable when executing the manipulated-variable time series, generated by the host-vehicle manipulated variable setting section, and additionally determines which of gaps defined between the peripheral vehicles traveling on a traffic lane of destination of lane-changing should be suited for an entry of the host vehicle when the manipulated variable decision section determines that the appropriate lane change by the host vehicle is achievable by execution of the manipulated-variable time series; and
(e) a support information presentation section that transmits information regarding a correspondence between a current host vehicle'"'"'s manipulated variable on the manipulated-variable time series determined by the manipulated variable decision section and at least one lane-changing enabling gap determined by the manipulated variable decision section, to the driver.

Abstract
A lane-changing support system includes a processing unit sets an assumed traffic-merging end, predicts a driving behavior of each peripheral vehicle, and generates at least one host vehicle'"'"'s manipulated-variable time series to be executed until the host vehicle reaches the assumed traffic-merging end. The processing unit determines whether the host vehicle'"'"'s lane change is appropriately achievable when executing the manipulated-variable time series, and additionally determines which of gaps defined between the peripheral-vehicles traveling on a traffic lane of destination of lane-changing should be suited for an entry of the host vehicle in case of a decision result that the appropriate lane change is achievable by execution of the manipulated-variable time series. The processing unit transmits information regarding a correspondence between a current host vehicle'"'"'s manipulated variable on the manipulated-variable time series and at least one lane-changing enabling gap to the driver.
