Lane Information

1. Data Flow Overview

The lane line simulation data flow starts from the SimOne simulation scene, where lane line information is perceived and acquired in real time using SimOne's built-in object-level camera. The data is transmitted via the Ethernet bus to the real-time target, where it is used to compare against the ECU's perception results. The data flow design must ensure the accuracy, latency, and synchronization of lane line data to meet the requirements of closed-loop control.

2. SimOne Configuration

(1) Add an object-level camera sensor

Select the ego vehicle, add an Object-Level Camera Sensor, and configure the camera parameters to ensure lane line information can be perceived correctly;

(2) Run the use case

Select a use case and run the corresponding ego vehicle use case to ensure the lane sensor generates simulation data correctly;

(3) Run Trans

3. Real-Time Target Configuration

(1) Load the SimOneLaneInfo model

• Select Simulation Model;

• Browse and select the SimOneLaneInfo model file;

• Load the SimOneLaneInfo model into the VeriStand project;

(2) Deploy the SimOneLaneInfo model

Deploy the VeriStand project to ensure the SimOneLaneInfo model can correctly receive the lane line simulation data sent by the Trans tool;

(3) Verify lane line data

Use the monitoring window in VeriStand to view signals in the SimOneLaneInfo model. Verify the accuracy and latency of the lane line data to ensure it meets the input requirements of the ECU perception algorithm;
