Automatic driving hardware-in-the-loop simulation test method and automatic driving hardware-in-the-loop simulation test system

Abstract

The invention provides an automatic driving hardware-in-the-loop simulation test method, and the method comprises the steps: receiving sensor data which comprises data packages of a plurality of sensors collected in the same time period, and enabling each data package to be marked with a time stamp representing the generation of data; subtracting the preset delay time from the data packet timestamp of the preset type of sensor to obtain a corrected timestamp; caching the data packets of the plurality of sensors in a cache region; reading data packets of a plurality of sensors in the cache region according to the sequence of the correction timestamps, and writing the data packets into a specified memory region; and reading the data packets of the plurality of sensors in the specified memoryarea in real time, converting the data packets of the plurality of sensors into electric signals, and transmitting the electric signals to a test device for testing. In addition, the invention also provides a hardware-in-loop test system.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a hardware-in-the-loop simulation test method and system for automatic driving. Background technique [0002] With the development of automobile intelligence, advanced driving assistance system (Advanced Driving Assistance System, ADAS) auxiliary function driving has gradually become standard equipment. The Hardware-in-Loop test (HIL) system for ADAS sensors has become the key to R&D efficiency. [0003] However, traditional HIL often provides image data directly through the display, that is, based on the HDMI interface transfer method. Since the data volume of image data is much larger than that of other formats, the image data provided by the above method cannot be accurately controlled. The clock cycle, resulting in the inability to achieve data synchronization with other sensors. Contents of the invention [0004] In view of this, it is necessary to provide a ha...
