Self-driving car test and how to self-driving the driver and guardian. Toyota Research Institute (TRI) presents the first demonstration of its self-driving vehicle platform, Guardian and Chauffeur. TRI's advances with Platform 2.1, the next iteration of the innovative TRI vehicle for advanced safety research for autonomous driving, performing several test maneuvers in a closed course. Platform 2.1 is the first research tool to test Guardian and Chauffeur systems on a single vehicle using the same technology suite of sensors and software. The driver is a pilot version of Toyota's SAE Level 4/5 autonomy in which the automated system is responsible for all driving tasks, while in Guardian mode, the automated driving system acts as a safety net for the human driver to help prevent an accident.
How does the driver enable the test vehicle to drive itself in a closed path.
We will demonstrate how the test vehicle's ability to drive itself in a closed lane and navigate around roadblocks will be demonstrated by the driver. The "Truck with Hay Bales" test demonstrates how the vehicle can detect unexpected objects in its path and make changes in the safe lane to avoid obstacles. "The Blocking Car" is a scenario in which the driver system detects a car parked in its lane and another vehicle traveling at the same speed in its adjacent lane. Here, the system slows the test vehicle to allow the adjacent vehicle to pass and makes a safe lane change around the parked vehicle that the vehicle returning to the original lane follows.
How do Guardian tests show the system's ability to protect the vehicle and its occupants.
Guardian tests demonstrate the system's ability to protect the vehicle and its occupants when the test vehicle encounters a potentially dangerous situation and take action if the driver does not react. Guardian also monitors the driver's eyes for distracted driving or drowsiness. In the "The Drowsy Driver" scenario, the Guardian system detects that the driver is asleep at the wheel when the vehicle approaches a bend in the road. When the driver closes his eyes and is not steering with the curve of the road, the system intervenes and directs the vehicle to keep it in the lane. Guardian's second scenario, "The Reveal," shows how the system can detect debris on the road in front of the vehicle that the driver might not see. When the vehicle in front of you veers off the road, Guardian notices the obstacle ahead and the driver takes the vehicle off the road, retaining control until the driver regains control of the vehicle.
How does the driver control the car on the front passenger side with a touch steering wheel.
On platform 2.1, TRI has created a second car control cockpit on the front passenger side with a fully functional touch steering wheel and acceleration and braking pedals. This dual cockpit setup allows efficient methods of transferring vehicle control between the human driver and the autonomous system to be experienced. It also supports the development of machine learning algorithms that can learn from expert human drivers and provide training for novice drivers.
Platform 2.1 also features:
A new high-resolution LIDAR system, from Luminar, offers a longer sensing range, a denser point cloud to better detect the locations of 3D objects, and a field of view that is the first to be dynamically configured, which means measuring points can be focused where sensing is most needed ;
An autonomy indicator designed in the dashboard with a consistent user interface via screens, colored lights and a tonal language associated with Guardian and Chauffeur;
Real-time display of LIDAR point cloud detection on the multimedia display in the central stack; An alert system in Guardian mode warns the driver of impending danger and prompts the driver to regain control after Guardian takes corrective action.
