Abstract

The embodiment of the invention discloses a rear protection device of a hydrogen transport vehicle. A vehicle-mounted ECU of the device determines the vehicle type of a rear vehicle based on a video image, and determines whether the rear vehicle collides with the hydrogen transport vehicle or not based on the relative speed and the vehicle distance according to various vehicle types; and when therear vehicle possibly collides with the hydrogen transport vehicle, a power assembly is controlled to drive the movable rear protection device to slide out of a frame assembly in a mode of sending anextending instruction to the power assembly, so that protection is formed, and the rear vehicle is prevented from colliding with a hydrogen storage device of the hydrogen transport vehicle during rear-end collision. Due to the fact that the movable rear protection device is connected to the frame assembly of the hydrogen transport vehicle in the sliding mode and extends out of the frame assembly only when the rear vehicle possibly collides with the hydrogen transport vehicle, the rear protection device in the embodiment of the invention does not occupy the length of the hydrogen transport vehicle, and the safety of the hydrogen transport vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a rear protection device of a hydrogen transportation vehicle. Background technique [0002] At present, with the development of economy and technology, the transportation speed has been greatly improved, and more and more freight transportation companies regard road transportation as the first choice, including hydrogen transportation. At present, in order to ensure the driving safety of the hydrogen transport vehicle, a rear protection device is provided at the rear of the vehicle. [0003] The rear protection device of the hydrogen transport vehicle in the prior art, in order to prevent the rear-end vehicle from touching the hydrogen storage device, the rear protection device is generally arranged at the rear of the hydrogen transport vehicle, and exceeds the length of the hydrogen transport vehicle itself, so that the hydrogen transport vehicle The increase ...
