Abstract

The invention discloses a positioning data sending method, a hardware-in-the-loop test device and electronic equipment, and relates to the technical field of automatic driving. The method comprises the following steps: collecting pre-collected positioning data in a first time period, wherein the positioning data comprises N frames of first positioning data and M frames of second positioning data; sending the N frames of first positioning data to the vehicle-mounted computing platform frame by frame from the first moment according to the preset sending frequency of the first positioning data; sending the M frames of second positioning data to the vehicle-mounted computing platform frame by frame from the first moment, calculating sleep time when each frame of second positioning data is sent, and sending the next frame of second positioning data to the vehicle-mounted computing platform when the sleep time is reached until all the M frames of second positioning data are sent. One embodiment of the invention has the following beneficial effects: the sending synchronism of two kinds of positioning data can be ensured, so that the two kinds of positioning data can be sent to the vehicle-mounted computing platform in the same time period.

Description

technical field [0001] The present application relates to data processing technology, in particular to the field of automatic driving technology, and in particular to a positioning data sending method, a hardware-in-the-loop testing device and electronic equipment. Background technique [0002] Hardware-In-the-Loop (HIL) testing technology is widely used in automobile R&D and testing. With the development of autonomous driving technology, hardware-in-the-loop testing technology is gradually applied to autonomous vehicles. In the hardware-in-the-loop test of autonomous driving, the positioning data of the vehicle comes from the data generated by the real road test, and these data need to be sent to the on-board computing platform. If multiple positioning data are involved, how to ensure that multiple positioning data are sent synchronously is directly related to whether the positioning module can work normally. Contents of the invention [0003] The present application pro...
