    摘要: A forward facing sensing system for a vehicle includes a radar sensor device disposed at the vehicle and having a sensing direction forward of the vehicle and an image sensor disposed behind the vehicle windshield so as to view forward of the vehicle through the windshield. A control includes an image processor operable to analyze image data captured by the image sensor in order to, at least in part, detect an object present forward of the vehicle. The control, responsive at least in part to processing of captured image data by the image processor and to sensing by the radar sensor, determines that a potentially hazardous condition may exist in the path of forward travel of the vehicle. The radar sensor device and the image sensor collaborate in a way that enhances determination of existence of the potentially hazardous condition in the path of forward travel of the vehicle.

    摘要: A system and method for calculating a virtual target path that is used to calculate an evasive steering path around a target object, such as a target vehicle, stopped in front of a subject vehicle. The method includes determining a potential field using a plurality of scan points that is a summation of two-dimensional Gaussian functions, where each Gaussian function has center defined by target object scan points and other object scan points. The method identifies a mesh grid in an X-Y plane where the mesh grid includes mesh grid points at locations where X and Y plane lines cross. The method identifies a local minimum point of the potential field for each X-plane line at each mesh grid point along the Y-plane crossing that X-plane line, where the local minimum point is a curve point. The method then connects the curve points to define the target path.

    摘要: A vehicle includes a radar sensor for detecting objects in the vehicle path. The radar sensor may become blocked by contaminants or debris. A controller monitoring the radar system may detect a radar blockage when a return signal magnitude is less than a threshold. A typical response may be to set a radar blockage diagnostic under such a condition. The controller may inhibit setting a radar blockage diagnostic when other data indicates that the radar sensor is not blocked. Data such as vehicle position, traffic information, camera images, and historical radar returns may be used. A controller may confirm a radar blockage diagnostic when other data indicates that the radar sensor may be blocked. Data such as temperature, vehicle position, surface roughness, automated brake interventions, and heating system status may be used. Return signal dependent functions may be operated based on the radar blockage diagnostic.

    摘要: The present invention relates to a method of identifying the hand of traffic applicable to a subject vehicle (3). The subject vehicle (3) travels in a first direction and has a first side and a second side. The method comprises tracking at least a first object vehicle (V) on the first side of the subject vehicle (3), and/or detecting the presence or absence of at least a first stationary target (T) on the first side of the subject vehicle (3). A direction of travel of each first object vehicle (V) is determined in relation to the subject vehicle (3). The hand of traffic is identified based on the direction of travel of each first object vehicle (V), and/or the presence or absence of each first stationary target (T). The invention also relates to a method of implementing Adaptive Cruise Control (ACC) using the hand of traffic information. The invention also relates to a control unit (1) for determining the hand of traffic.
