Embodiment Construction

[0059] Such as figure 1 As shown, the present invention provides a steering system endurance test control method, including: obtaining user driving data and preprocessing to obtain steering system related data; calculating the number of times and conditions for the user to perform various steering conditions according to the steering system related data; A durability cycle command is generated according to the times and conditions of various steering conditions, and the durability cycle command is sent to the durability test device, so that the durability test device tests the steering system.

[0060] Compared with the prior art, the present invention discloses a steering system durability test control method that collects user driving data, obtains the actual driving conditions of the user by analyzing the user driving data, and determines the durability test according to the actual working conditions. Generate durability cycle commands according to the number and conditions...

Abstract

The invention discloses a steering system endurance test control method and device, a storage medium and a system, and the method comprises the steps: obtaining and preprocessing user driving data, and obtaining the related data of a steering system; calculating the times and conditions of executing various steering conditions by the user according to the steering system related data; generating adurability cycle instruction according to the times and conditions of various steering conditions, and sending the durability cycle instruction to the durability test device, so that the durability test device tests the steering system. According to the times and conditions of various steering conditions, a durability cycle instruction is generated to control the durability test device to test the steering system, and the steering condition of user driving and durability verification during development of the steering system are directly associated, so that the durability verification is closer to the actual use condition of the user; compared with a conventional steering system, verification is more comprehensive, the risk of failure of the steering system after mass production is reduced, and the problems that an existing endurance test method is poor in relevance with Chinese user driving conditions, and verification of the steering system is insufficient are solved.

Description

technical field [0001] The invention relates to the field of vehicle steering systems, in particular to a steering system endurance test control method, device, storage medium and system. Background technique [0002] At present, statistical research on user driving conditions at home and abroad is mainly used in: 1. The establishment of driver models in automatic driving and the control of vehicle longitudinal motion, such as the paper "Typical Working Condition Types of Adaptive Cruise Control Based on Natural Driving Conditions" Summary"; 2. Calibration of powertrain and optimization of energy management system, such as the paper "Research on Energy Management Strategy of Plug-in Hybrid Electric Vehicle Based on Driving Intention and Working Condition Recognition". The research on the user's driving conditions lacks the research on the working conditions of the automobile steering system, and has not been applied to the durability test method of the steering system.
