Description

Based on the lane change prior-warning device of collaborative truck
Technical field
The present invention relates to a kind of lane change prior-warning device based on collaborative truck and the collaborative truck lane change method for early warning based on this device.
Background technology
China is national road fatalities official statistics in recent years: calendar year 2001 10.6 ten thousand, 2002 10.9 ten thousand, 2003 10.4 ten thousand, 2004 9.4 ten thousand, 2005 9.8 ten thousand, 2006 8.9 ten thousand, 2008 7.3 ten thousand.2009, China's automobile guarantee-quantity accounted for 3 percent of world car recoverable amount, but 1 16 of the toll on traffic Que Zhan world, numeral is startling.By showing the analysis of traffic hazard, the traffic accident of more than 80% caused because driver does not react in time, bump against between the vehicle more than 65% and belong to rear-end impact, from the reason that traffic hazard of knocking into the back occurs, quite a few rear-end collision is had all to be caused by driver's lane change, if can remind driver in time before the traffic hazard produced due to lane change occurs, the traffic hazard that a lot of lane change produces then can be avoided.
For solving the problem that knocks into the back because lane change causes, many lane changes assist prior-warning device to be devised, they mostly rely on various sensor (as laser range finder, millimetre-wave radar, machine vision etc.) directly to obtain the spacing of two cars before and after in the same travel direction in different track, recycle horizontal safe distance between vehicles model and judge whether to report to the police.Such as, but involve great expense due to adopted range sensor or in performance, existing defects can not well adapt to all kinds of road environment, the lane change of view-based access control model assists prior-warning device to there is awkward shortcoming under the severe weather conditions such as heavy rain dense fog; The problems such as the wrong report when lane change based on laser or radar assists prior-warning device to there is non-vehicle barrier.Be only limitted to another car on different track because of detection dangerous information simultaneously, dangerous information can produce time delay and add up in wagon flow during back-propagation, the operating delay of front vehicles directly jeopardizes vehicle safety below, therefore such lane change early warning system avoid the chain of rings knock into the back on act on less.
In order to solve the problem, the invention provides a kind of lane change based on collaborative truck and assisting prior-warning device.
Summary of the invention
Object of the present invention provides a kind of lane change prior-warning device based on collaborative truck and the lane change method for early warning based on this device.Different track is calculated and same travel direction is got on the bus and car prediction of collision by truck traffic, and then reach active safety early warning, effectively prevent the wrong report problem during non-vehicle barrier of vision sensor by the impact of the factor such as illumination, environment and laser or radar sensor, and early warning information can be passed to more vehicles by truck traffic, improve vehicle active safety energy, expand vehicle active safety scope.For achieving the above object, the present invention by the following technical solutions:
