Intelligent automobile high-speed working condition comprehensive safety performance detection method

Abstract

The invention discloses an intelligent automobile high-speed working condition comprehensive safety performance detection method, which comprises the following steps on a detection platform: (1) ASR function detection: simulating a road condition that the rotating speed of a driving wheel is lower than the rotating speed of a driven wheel on the detection platform, and then judging whether the ASR function of a to-be-detected automobile is started or not and whether the performance is normal or not; (2) driving assistance system detection: simulating a driving scene on the detection platform, and judging whether the function and performance of the driving assistance system of the to-be-detected vehicle are normal or not by changing the relative position of the AGV and the to-be-detected vehicle; and (3) EBS function detection: simulating different load states of the to-be-detected vehicle by adjusting the inertia of a flywheel connected with a roller on the detection platform, and detecting the EBS function and performance of the to-be-detected vehicle in different load states. According to the invention, the problem that the ASR function and the automobile driving assistance system cannot be effectively detected is solved, the detection process of the EBS is also perfected, and the performance stability and reliability of the EBS are comprehensively detected.

Description

Technical field [0001] The present invention relates to a method of detecting safety performance in automotive high speed states. Background technique [0002] The safety of the car in high-speed state is related to the safety of the driving personnel. The automobile factory must first meet the safety requirements of "GB7258-2017 motor vehicle operation safety technical conditions", complete the system, braking distance, brake deceleration and braking stability. The Chinese invention patent "Automotive Emissions and Automotive Safety Test Method" of CN112798299A proposed a car inspection method, which can efficiently complete the ABS inspection section, EBD inspection part and environmental inspection. [0003] However, existing automotive test methods also have the following defects: [0004] (1) It is not possible to test the traction control system (ASR). ASR is used to enable the car to achieve better traction in various driving conditions. When the car accelerates, if the tr...
