Problems solved by technology

At present, the components of the wire control system of engineering vehicles can report fault information such as fault codes, and have corresponding protections, but the definition of the fault level of each main component is only for its own faults, not from the perspective of the whole vehicle, and Some unexplained faulty components cannot be fed back, but these faults are necessary for the safety of automatic driving, such as engine flameout for unknown reasons, component disconnection, lift blockage, etc.

Abstract

The invention discloses a fault diagnosis method for a drive-by-wire system of an automatic driving engineering vehicle. The method comprises the steps of defining a whole vehicle fault of the automatic driving engineering vehicle, which comprises a part fault, a fault which is judged by a drive-by-wire controller according to vehicle information and does not report parts but affects the safety of unmanned driving, and a fault of the drive-by-wire controller. The invention further discloses a safety protection method for the drive-by-wire system of the automatic driving engineering vehicle. According to the invention, comprehensive diagnosis, analysis and safety protection can be carried out on the fault of the automatic drive-by-wire engineering vehicle, and the unmanned driving safety is improved.

Description

Technical field [0001] The present invention relates to the field of drivatic technology. More specifically, the present invention relates to a method of fault diagnosis and safety protection for automatic driving engineering lane control systems. Background technique [0002] With the development of science and technology, unmanned has become a research hotspot in the field of vehicle fields. Automatic driving engineering vehicles require a perfect, reasonable approach to troubleshooting, analysis, and treatment due to the "human" information processing center. Currently, the engine wire control system components can be reported to fault information such as fault code, and have made corresponding protection, but the definition of the fault rating of each major component is only for its own failure, but does not define from the perspective of the vehicle, and Some fault components cannot be given, but these faults are necessary for automatic driving safety, such as engine unknown...
