The <code>trajectory_follower</code> module generates a vehicle control command to follow the reference trajectory received from the planning module. The command includes, for example, the desired steering angle and target speed. The <code>vehicle_command_gate</code> is responsible for filtering the control command to prevent abnormal values and then sending it to the vehicle. This gate also allows switching between multiple sources such as the MRM (minimal risk maneuver) module or some remote control module, in addition to the trajectory follower.</p> <p>The Autoware control system is designed as a platform for automated driving systems that can be compatible with a diverse range of vehicles.</p> <p>The control process in Autoware uses general information (such as target acceleration and deceleration) and no vehicle-specific information (such as brake pressure) is used. Hence it can be adjusted independently of the vehicle's drive interface enabling easy integration or performance tuning.</p> <p>Furthermore, significant differences that affect vehicle motion constraints, such as two-wheel steering or four-wheel steering, are addressed by switching the control vehicle model, achieving control specialized for each characteristic.</p> <p>Autoware's control module outputs the necessary information to control the vehicle as a substitute for a human driver. For example, the control command from the control module looks like the following:</p> <pre><code>- Target steering angle\n- Target steering torque\n- Target speed\n- Target acceleration\n</code></pre> <p>Note that vehicle-specific values such as pedal positions and low-level information such as individual wheel rotation speeds are excluded from the command.</p>"},{"location":"design/autoware-architecture/control/#vehicle-adaptation-design","title":"Vehicle Adaptation Design","text":""},{"location":"design/autoware-architecture/control/#vehicle-interface-adapter","title":"Vehicle interface adapter","text":"<p>Autoware is designed to be an autonomous driving platform able to accommodate vehicles with various drivetrain types.</p> <p>This is an explanation of how Autoware handles the standardization of systems with different vehicle drivetrains. The interfaces for vehicle drivetrains are diverse, including steering angle, steering angular velocity, steering torque, speed, accel/brake pedals, and brake pressure. To accommodate these differences, Autoware adds an adapter module between the control component and the vehicle interface.

Therefore, the response time of each callback should be as small as possible. If Autoware appears to be slow, it is imperative to conduct performance measurements and implement improvements based on the analysis. However, Autoware is a complex software system comprising numerous ROS 2 nodes, potentially complicating the process of identifying bottlenecks. To address this challenge, we will discuss methods for conducting detailed performance measurements for Autoware and provide case studies. It is worth noting that multiple factors can contribute to poor performance, such as scheduling and memory allocation in the OS layer, but our focus in this page will be on user code bottlenecks. The outline of this section is as follows:</p> <ul> <li>Performance measurement<ul> <li>Single node execution</li> <li>Prepare separated cores</li> <li>Run single node separately</li> <li>Measurement and visualization</li> </ul> </li> <li>Case studies<ul> <li>Sensing component</li> <li>Planning component</li> </ul> </li> </ul>"},{"location":"how-to-guides/integrating-autoware/tuning-parameters-and-performance/evaluating-real-time-performance/#performance-measurement","title":"Performance measurement","text":"<p>Improvement is impossible without precise measurements.

This tool records the input topics of a specific node during the entire Autoware operation and replays it in a single node with the same logic. The tool relies on the <code>ros2 bag record</code> command, and the recording of service/action is not supported as of ROS 2 Humble, so nodes that use service/action as their main logic may not work well.</p>"},{"location":"how-to-guides/integrating-autoware/tuning-parameters-and-performance/evaluating-real-time-performance/#prepare-separated-cores","title":"Prepare separated cores","text":"<p>Isolated cores running the node to be measured must meet the following conditions.</p> <ul> <li>Fix CPU frequency and disable turbo boost</li> <li>Minimize timer interruptions</li> <li>Offload RCU (Read Copy Update) callback</li> <li>Isolate the paired core if hyper-threading enabled</li> </ul> <p>To fulfill these conditions on Linux, a custom kernel build with the following kernel configurations is required.

By examining the methods, techniques, and tools employed in these case studies, readers can gain a better understanding of the practical aspects of optimizing complex software systems like Autoware.</p>"},{"location":"how-to-guides/integrating-autoware/tuning-parameters-and-performance/evaluating-real-time-performance/#sensing-component","title":"Sensing component","text":"<p>First, we will explain the procedure for performance improvement, taking the node <code>ring_outlier_filter</code> as an example. Refer to the Pull Request for details.</p> <p>The following figure is a time-series plot of the turnaround time of the main processing part of <code>ring_outlier_filter</code>, analyzed as described in the \"Performance Measurement\" section above.</p> <p></p> <p>The horizontal axis indicates the number of callbacks called (i.e., callback index), and the vertical axis indicates the turnaround time.</p> <p>When analyzing the performance of the sensing module from the viewpoint of performance counter, pay attention to <code>instructions</code>, <code>LLC-load-misses</code>, <code>LLC-store-misses</code>, <code>cache-misses</code>, and <code>minor-faults</code>.</p> <p>Analysis of the performance counter shows that the largest fluctuations come from <code>minor-faults</code> (i.e., soft page faults), the second largest from <code>LLC-store-misses</code> and <code>LLC-load-misses</code> (i.e., cache misses in the last level cache), and the slowest fluctuations come from instructions (i.e., message data size fluctuations). For example, when we plot <code>minor-faults</code> on the horizontal axis and turnaround time on the vertical axis, we can see the following dominant proportional relationship.</p> <p></p> <p>To achieve zero soft page faults, heap allocations must only be made from areas that have been first touched in advance. We have developed a library called <code>heaphook</code> to avoid soft page faults while running Autoware callback. If you are interested, refer to the GitHub discussion and the issue.</p> <p>To reduce LLC misses, it is necessary to reduce the working set and to use cache-efficient access patterns.</p> <p>In the sensing component, which handles large message data such as LiDAR point cloud data, minimizing copying is important. A callback that takes sensor data message types as input and output should be written in an in-place algorithm as much as possible. This means that in the following pseudocode, when generating <code>output_msg</code> from <code>input_msg</code>, it is crucial to avoid using buffers as much as possible to reduce the number of memory copies.</p> <pre><code>void callback(const PointCloudMsg &amp;input_msg) {\nauto output_msg = allocate_msg&lt;PointCloudMsg&gt;(output_size);\nfill(input_msg, output_msg);\npublish(std::move(output_msg));\n}\n</code></pre> <p>To improve cache efficiency, implement an in-place style as much as possible, instead of touching memory areas sporadically.

This is a wasteful copying process and should be avoided. We should eliminate unnecessary type conversions by removing dependencies on PCL (e.g., https://github.com/tier4/velodyne_vls/pull/39). For large message types such as map data, there should be only one instance in the entire system in terms of physical memory.</p>"},{"location":"how-to-guides/integrating-autoware/tuning-parameters-and-performance/evaluating-real-time-performance/#planning-component","title":"Planning component","text":"<p>First, we will pick up <code>detection_area</code> module in <code>behavior_velocity_planner</code> node, which tends to have long turnaround time.

Let <code>N</code> be the size of <code>point_clouds</code> and <code>M</code> be the size of <code>detection_areas</code>, then the computational complexity of this program is O(N^2 * M), since the complexity of <code>within</code> is O(N). Here, given that most of the point clouds are located far away from a certain detection area, a certain optimization can be achieved. First, calculate the minimum enclosing circle that completely covers the detection area, and then check whether the points are contained in that circle. Most of the point clouds can be quickly ruled out by this method, we don\u2019t have to call the <code>within</code> function in most cases.

Therefore, we access the contents of the point clouds and paths multiple times using for-loops. In most cases, the bottleneck lies in these naive for-loops.

For example, when we plot <code>minor-faults</code> on the horizontal axis and turnaround time on the vertical axis, we can see the following dominant proportional relationship.</p> <p></p> <p>To achieve zero soft page faults, heap allocations must only be made from areas that have been first touched in advance.

A callback that takes sensor data message types as input and output should be written in an in-place algorithm as much as possible.

This is a wasteful copying process and should be avoided. We should eliminate unnecessary type conversions by removing dependencies on PCL (e.g., https://github.com/tier4/velodyne_vls/pull/39).

First, calculate the minimum enclosing circle that completely covers the detection area, and then check whether the points are contained in that circle.
