Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rapid vehicle performance testing method based on the automobile information system, which solves the problem that the automobile power detection will be affected by the friction force between the automobile friction force and the roller, and it is easy to It leads to the problem of inaccurate measurement accuracy, which in turn affects the problem of the average size of the car's final performance index detection

Embodiment 1

[0024] The present invention provides a technical solution: a rapid vehicle performance testing method based on an automobile information system, comprising the following steps:

[0025] S1: Clean the exterior of the vehicle first, then pick out the stones trapped in the tread pattern of the car, and at the same time perform the height detection operation of the engine oil level of the car engine bottom case to make it within the allowable height range, and at the same time check the automatic transmission (Hydraulic torque converter) liquid level is checked to make it within the allowable height range.

[0026] S2: Then check the engine cooling system to ensure that the cooling system can work normally.

[0027] S3: Then maintain the car engine and chassis to ensure that the oil supply system and ignition system are in the best working condition.

[0028] S4: Then detect the tire pressure of the four tires of the car to be tested. When the tire pressure is lower than the nor...

Embodiment 2

[0036] The specific difference from Embodiment 1 is: in S4, only the tire pressure of each tire of the automobile is measured, and the average friction coefficient of the driving wheel is not measured, so that the actual operation is carried out and the calculated result is obtained.

Abstract

The invention discloses a rapid whole vehicle performance test method based on an automobile informatization system. According to the rapid whole vehicle performance test method based on the vehicle informatization system, the tire pressure of four tires of a vehicle is detected while the rolling friction force of the whole driving system of the vehicle is measured through a dynamometer, and then the friction force of a single wheel is obtained by dividing the measured value by the number of the wheels according to the number of the driving wheels, so that the problem that during existing automobile power detection, due to the fact that the influence of the friction force between automobile friction force and a roller exists, the measurement precision is not accurate easily, and then the average detection number of final performance indexes of an automobile is influenced is solved.

Description

technical field [0001] The invention relates to the technical field of automobile performance testing, in particular to a rapid vehicle performance testing method based on an automobile information system. Background technique [0002] The performance indicators usually used to evaluate automobiles mainly include: power, fuel economy, braking, handling stability, ride comfort and passability, etc. Under certain conditions of use, the ability of a car to work at the highest efficiency is called a car Use performance, which is the structural characteristic that determines the utilization efficiency and convenience of the car. The car basically includes the following main performances, capacity: rated loading mass, unit loading mass, effective volume per unit of cargo box, unit area of ​​cargo box, number of seats and The number of people who can stand; Ease of use: ease of operation, rapidity of leaving the vehicle, convenience of passengers getting on and off and cargo loadin...
