Embodiment Construction

[0018] figure 1 A schematic diagram of a novel vehicle fault detection method involved in the present invention is given. As can be seen from the figure, the method consists of the following logical modules.

[0019] 1. The vehicle subsystem division module divides the whole vehicle into several subsystems, including but not limited to engine system, fuel supply system, gearbox system, electrical system, body system, brake system, steering system, suspension system, tires, safety systems, body systems, lighting systems.

[0020] 2. The detection item division module divides each subsystem into several detection items. For specific division, refer to the attached figure 2 .

[0021] 3. The detection item score calculation module assigns a score IS[n] to each detection item through the sensor or detection circuit on the vehicle or the result of manual detection.

[0022] 4. Introduce the detection item weight parameter P[n] and score correction value Offset[n]. The weight ...

Abstract

The invention relates to a novel vehicle fault scoring method. The method comprises the steps that first, an entire vehicle is divided into a plurality of subsystems, and each subsystem is further divided into a plurality of measurable test items; then data resources, weight parameters and score correcting values are defined according to all the test items, the scores of all the test items are obtained according to an algorithm, and then the overall score of a vehicle is obtained through accumulation. According to the novel vehicle fault scoring method, description is visual, the performance is reliable, operability is high, and a vehicle owner can visually learn the serious condition of current vehicle faults through a simple score no matter whether the vehicle owner has vehicle professional knowledge or not.

Description

technical field [0001] The invention relates to a novel vehicle fault scoring method, which belongs to the fields of automobile engineering and data processing engineering. Background technique [0002] In traditional vehicles, due to the limitation of external factors such as cost, size and installation location, vehicles can only provide users with limited information through specific identifiers, codes or simple text, and users cannot fully understand the status of the entire vehicle or the vehicle The state of certain subsystems. Or the car owner needs to drive the vehicle to a professional repair shop to test the vehicle through a professional tool team, but the results are very complicated, and the general car owner cannot understand the meaning and cannot judge the severity of the vehicle failure. In fact, what car owners need is a simple and intuitive representation to understand the severity of vehicle failures. Contents of the invention [0003] The purpose of ...
