Problems solved by technology

[0003] However, the ACC system may not be able to correctly handle merging traffic situations from on-ramps, for example on highways
For example, the ACC system in the host vehicle may fail to detect the merging vehicle as being in the same lane as the host vehicle

Embodiment Construction

[0018] Before describing in detail any embodiments of the invention, it is to be understood that the invention is not limited in application to the details of construction and arrangement of parts set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways.

[0019] figure 1 A host vehicle 10 is shown equipped with an adaptive cruise control ("ACC") system 12 . The ACC system operates similar to a conventional cruise control system. In particular, the ACC system is activated by user interface controls (eg, one or more buttons or levers) that can be mounted on or adjacent to the steering wheel. Using the user interface controls, the user is able to enable and disable the ACC system, set a target speed for the vehicle, or adjust a pre-set target speed. Additionally, the user is able to depress or activate the brake pedal to disable the cruise control system...

Abstract

Methods and systems for controlling the speed of a host vehicle during an on-ramp merging situation. One method includes identifying a position of an upcoming on-ramp merging with a lane where the host vehicle is currently traveling based on lane markings identified in an image captured by a forward-facing image sensor mounted on the host vehicle, detecting a merging vehicle on the upcoming on-ramp, and determining a speed of the merging vehicle. The method also includes automatically, at a control unit, adjusting a speed of the host vehicle based on the speed of the merging vehicle.

Description

technical field [0001] The present invention relates to systems and methods for implementing adaptive cruise control. Background technique [0002] Conventional cruise control systems control the speed of the host vehicle at a level set by the user. Adaptive cruise control ("ACC") systems also control the host vehicle's speed at a user-set level. However, when a vehicle is detected within a predetermined distance in front of the host vehicle, the ACC system automatically reduces the host vehicle's speed below a user-set level. Accordingly, the ACC system prevents the host vehicle from colliding with a vehicle in front of the host vehicle traveling at a speed slower than a user-set level. [0003] However, ACC systems may not be able to properly handle merging traffic situations from on-ramps, such as on highways. For example, the ACC system in the host vehicle may not be able to detect the merging vehicle as a vehicle in the same lane as the host vehicle. Therefore, ACC ...
