The camera acquires consecutively in real time image frames including images of an object within the field of view of the camera. Range to the object from the moving vehicle is determined in real time. A dimension, e.g. a width, is measured in the respective images of two or more image frames, thereby producing measurements of the dimension. The measurements are processed to produce a smoothed measurement of the dimension. The dimension is measured subsequently in one or more subsequent frames.

When a relative transverse deviation obtained by subtracting the transverse travelling distance from the relative transverse distance resides within a range and that state continues to exist over a predetermined time period, it is judged that there is a collision possibility of the subject vehicle with the oncoming vehicle, and automatic steering is performed so as to avoid a collision.

Conventional file-based engineering design data for an engineering model are represented by a plurality of components. Each component has a unique identifier, a set of fields, each field having a data type and a data value, and a program which interprets and modifies the fields. The plurality of components are stored in a repository of a server. The repository also stores a history of any changes made to the components. A plurality of client computers are bidirectionally connected to the server. Each client computer may obtain the current version of the components and may send locally edited versions of the components back to the server to replace the current versions in the repository. At the client computer, the user interacts with the components using conventional file-based software. Before locally edited versions of the components are committed to the server to replace the current versions, a synchronization and merging process occurs whereby the latest version of the components are downloaded to the client computer and are compared to the locally edited version of the components to detect resolvable (compatible) and unresolvable (incompatible) conflicts therebetween. The commit process is performed only if no unresolvable conflicts exist between the two versions of the components. To facilitate translation between file-based data and components, a schema is written to "wrap" each of the engineering file formats. Each schema is a set of classes that capture all of the information in the file-based data.
