Embodiment Construction

[0044] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding and should be considered as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

[0045] The large-scale application of wire-controlled systems will lead to increasingly complex electronic and electrical systems of vehicles, which will make the safety problems of the whole vehicle increasingly prominent. Typical events include Toyota's throttle loss, Prius hybrid vehicle braking system failure, and a new energy vehicle breaking down on a highway.

Abstract

The invention discloses a method, device and equipment for adjusting system faults and a computer readable medium, and relates to the technical field of computers. According to one specific embodiment, the method comprises the steps that vehicle disturbance is input into a vehicle model, the vehicle model is influenced by a system fault, and the vehicle disturbance is used for simulating disturbance borne by a vehicle in the running process; inputting the vehicle disturbance into a vehicle observation model, and outputting correction parameters of the vehicle model by the vehicle observation model; the correction parameters are input into a state feedback controller, and the state feedback controller outputs fault-tolerant control parameters; and in the vehicle model, inputting the vehicle disturbance and the fault-tolerant control parameters again to correct the system fault in the vehicle model. According to the embodiment, adjustment of system faults can be simplified, and timely and accurate adjustment of the system faults is realized.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, and in particular, to a method, apparatus, device and computer-readable medium for adjusting system faults. Background technique [0002] With the development of vehicle intelligence and electrification, various wire-controlled technologies, such as: wire-controlled steering, wire-controlled braking, and wire-controlled drive, are applied to vehicles. It enables various advanced control systems, such as adaptive cruise (ACC), automatic emergency braking (AEBS), lane keeping (LKS) and other systems to be applied on a large scale. [0003] In the process of implementing the present invention, the inventor finds that there are at least the following problems in the prior art: the existing control-by-wire execution system takes active fault-tolerant control, and usually performs control law or controller reconfiguration according to fault information. The above method not only need...
