A computer-implemented method and system for extracting and validating structured vehicle title data using a machine-learned pipeline. A user interface on a client device enables users to upload an image of a physical vehicle title. An optical character recognition (OCR) module extracts text from the image, and a preprocessing engine constructs a multi-modal input tensor comprising the image, OCR output, and schema-based structured data templates. The tensor is input to a machine-learned model that outputs a structured data object including vehicle, title, and ownership information. A validation module cross-references this output with external title records to generate validation metadata. Based on the validation, the system performs actions such as lien registration or issuing user notifications. The model may be trained using multi-modal training data including annotated title images and structured templates. The structured data output and validation results are encoded in a machine-readable format for downstream use.

A vehicle control device includes one or more processors. When a prespecified first requirement is met, the one or more processors activate engine start lock that prohibits starting of an engine of a vehicle. After activating the engine start lock, the one or more processors acquire a second request for deactivating the engine start lock from a user of the vehicle who is different from an owner of the vehicle. When the second request is acquired, the one or more processors determine whether to permit deactivation of the engine start lock based on a predetermined condition. When it is determined to permit deactivation of the engine start lock, the one or more processors deactivate the engine start lock.

A processor of a vehicle control device: acquires regular vehicle stop position information indicating a regular vehicle stop position of a vehicle from a database that stores history information on a vehicle stop position of the vehicle; when it is detected that the vehicle has stopped, requests latest position information on the vehicle; acquires the latest position information on the vehicle; when the vehicle meets a prespecified requirement for engine start lock, determines whether to activate the engine start lock of the vehicle by at least comparing the regular vehicle stop position information and the latest position information; and when it is determined to activate the engine start lock, activates the engine start lock.
