Vehicle fault code displaying method and device

Abstract

The embodiment of the invention discloses a vehicle fault code displaying method. The method comprises the steps of acquiring a vehicle fault code; judging whether the acquired fault code exists in a first fault code library, and displaying the fault code and the fault information corresponding to the fault code if yes, wherein the numerical system of fault codes in the first fault code library is consistent with the numerical system of the acquired fault code, and the fault codes and fault information in the first fault code library are mapped in the programming language. Correspondingly, the embodiment of the invention discloses a vehicle fault code displaying device. According to the vehicle fault code displaying method and device, the purposes of improving vehicle fault handling efficiency and reducing potential safety hazards are realized.

Description

technical field [0001] The invention relates to the field of engineering machinery vehicles, in particular to a vehicle fault code display method and device. Background technique [0002] Because the working environment of construction machinery vehicles is often relatively harsh, it will often cause vehicle failures. The work involving construction machinery vehicles generally has a high risk factor, and it is extremely important to display the fault information to the operator in time after the vehicle breaks down. In the prior art, the fault codes of the vehicle and the meanings corresponding to the fault codes are compiled into electronic books or pictures and displayed on the display. Since the monitor accesses e-books in units of pages and accesses pictures in units of sheets, a page of e-book or a picture usually contains multiple fault codes, so the monitor cannot accurately locate a specific fault code when accessing an e-book or picture. The operator needs to jud...

Problems solved by technology

Since the monitor accesses e-books in units of pages and accesses pictures in units of sheets, a page of e-book or a picture usually contains multiple fault codes, so the monitor cannot accurately locate a specific fault code when accessing an e-book or picture. The operator needs to judge or guess which fault code it is according to the condition of the vehicle, which greatly reduces the processing efficiency of vehicle faults and increases safety hazards

[0003] However, if only one fault code is recorded on each page of e-book or picture, it will take up a lot of display memory, which will easily lead to a slowdown in the response speed of the display operation, and even a "black screen" phenomenon, which seriously affects the operator's understanding of the vehicle status. Real-time monitoring reduces the processing efficiency of vehicle failures
