Problems solved by technology

[0007] In the prior art, the OBU has a single function, and only supports the electronic non-parking toll deduction function, and does not have the function of a car driving recorder. Therefore, a new type of OBU is needed to increase competitiveness by integrating the function of a driving recorder.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The core of the present invention is to provide a product form that integrates the OBU into the driving recorder or integrates the driving recorder into the OBU, and a technical solution for realizing resource sharing in this product form.

[0026] Such as figure 1 As shown, an OBU with a display interface that supports the driving record function, the host includes a camera, an OBU module, etc., directly uses the ACC power supply through the connecting line, and connects to the vehicle screen through the connecting line.

[0027] Main control MCU: the core of the OBU, which runs the operating system and is responsible for controlling each module, camera, display, and SD storage interface of the OBU. Record the transaction information and save it in the user card and the memory of the ESAM operation module, record and store it in the SD...

Abstract

The invention relates to an on board unit (OBU) supporting a driving record function and with a display interface, and belongs to the intelligent traffic field. In the prior art, the function of the OBU is single because the OBU only supports an electric toll collect (ETC) function and does not has the function of a vehicle traveling data recorder. The OBU supporting the driving record function and with the display interface integrates an OBU function module to the inside of the vehicle traveling data recorder with the display interface; the whole machine can be directly fixed to a windshield glass through 3M glue; the OBU is powered by a vehicle-mounted ACC interface through a convertor; and the display interface is used for providing connecting lines to be connected to a vehicle-mounted screen or an intelligent mobile terminal, on which video can be checked and played, and ETC transaction records can be inquired. By adopting the OBU with the function of the vehicle traveling data recorder being integrated, human-computer interfaces of screen, voice and the like can be shared, and the human-computer interface of the single OBU is enriched.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a vehicle-mounted unit with a display interface supporting a driving recording function. Background technique [0002] The emergence of the ETC system (Electric Toll Collect, electronic non-stop toll collection) has changed the traditional manual toll collection method, allowing vehicles to complete the toll payment process without stopping when passing through the toll booths of expressways, bridges or tunnels, greatly improving The utilization rate of roads increases the speed of vehicles, reduces traffic congestion, and reduces carbon emissions to a certain extent. At the same time, it also reduces the labor demand of toll stations and reduces the operating costs of toll lanes. The non-parking charging method is adopted by more and more countries and cities. [0003] ETC electronic non-stop toll collection system consists of a lane controller, a roadside...
