Abstract

The invention relates to the technical field of vehicles, and discloses a vehicle climbing test method and a test system. The test method includes: S1, preparation steps for the test environment and the test vehicle before the test; S2, pre-testing the test vehicle and the chassis dynamometer. Hot step; S3, carry out road sliding test to the test vehicle, and record the operating data in the test process; S4, carry out data analysis and comparison according to the data recorded in step S3, and judge whether the climbing performance of the vehicle meets the design Require. The invention adopts the chassis dynamometer to simulate the actual track to test the climbing performance of the vehicle, and collects the running data of the vehicle during the test. The data collection process is simple, convenient and fast, and the collected data has high precision. The test method is safe and can greatly reduce the test cost.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to an automobile climbing test method and a test system. Background technique

[0002] Vehicle test is the most important method to verify vehicle performance, and plays an important role in the process of vehicle development and verification, among which climbing performance is an important factor to measure the power of vehicle engine.

[0003] The traditional car climbing test is based on the outdoor road. During the test, data collection is inconvenient. For example, the car's maximum climbing test is very difficult and dangerous, and the test accuracy is poor; the repeatability is poor. Poor and greatly affected by external environmental conditions, it is difficult to test the maximum climbability of the car. Contents of the invention
