Velodyne demonstrates a PAEB system based on laser radar

Affected by new crown epidemics, the number of miles of the whole of the US people in 2020 decreased by 13%, but the number of deaths caused by vehicle accidents increased by 8%.

The well-known laser radar company VELODYNE LIDAR recently showed how to significantly improve pedestrian automatic emergency braking system (PAEB, PEDESTRIAN Automatic Emergency Braking).

This technology is expected to save thousands of lives every year.

In October 2020, Velodyne issued a white paper, called for the performance test of the driving assistance system, should increase the testing of the dark night scene.

Because the current auxiliary driving system performance test is mainly for the daytime scene.

This largely ignores the huge risks brought by the auxiliary driving system in dim light.

According to the report of the US National Highway Traffic Safety Administration (NHTSA), 80% of pedestrian death accidents happened in the case of dim light.

In its newly released video, Velodyne showed us PAEB solutions based on laser radar.

Velodyne’s PAEB solution contains:

Velodyne Solid State Laser Radar Velarray

Special software Vella

Solid-state laser radar can be easily embedded in all parts of the vehicle body behind the windshield, and Vella software interprets the laser radar data to avoid and mitigate the collision of moving and static objects.

With predictive collision monitoring, Vella compares the trajectory of the vehicle with other road users and objects to identify and avoid the upcoming collision scenarios.

The test results show that this program exhibits reliable driving assistance in a dim light traffic environment, basically completes the same system based on radar and camera.

In the test results displayed by Velodyne, the PAEB system using millimeters and cameras failed in the six night scenes, while the PAEB solution equipped with laser radar is avoided in six scenes. collision.

Based on independent test results, the NHTSA and the US Auto Association (AAA) also believe that only the PAEB system of millimeters and camera technology is highly deficiencies in the dark conditions.

Velodyne will share its PAEB test methods and research results from other manufacturers in NHTSA and automotive security.

NHTSA has a pending proposal to update its new car evaluation plan (NCAP), and plan to increase the advanced driving assistance system (ADAS) functionality including PAEB.

Velodyne Ceo Anand Gopalan said:

“Our PAEB test plan clearly shows that regulators and testing institutions need to include night conditions into PAEB assessment procedures. Everyone, especially automakers and drivers, and hope that advanced driving assistance systems such as PAEB can be in various light environments. Effectively play a role, especially the night in patient death.

We believe that Velodyne’s laser radar data and Vella processing software have proven to be effective, which can be put into use, and it is possible to save thousands of pedestrians. “

Attached to Velodyne PAEB Test Method:

Velodyne PAEB test is carried out at night, no street lights, ambient lighting is less than 1 Lex, which is a separate test facility.

Two vehicles participating in the test take a straight line at a speed of 30 miles per hour.

During the test, the two tests of the two test vehicles are open.

The fixed children and adult pedestrian virtual targets are used in accordance with the test procedures specified in the US Highway Safety Insurance Association (IIHS) and the EU NCAP.

A total of six scenarios were evaluated, and the two cars were tested five times in various scenarios or collided with the target three times to minimize the damage to the target and vehicle.

Test scenarios for assessing vehicles include:

The vehicle is overlapping 50% over the adult (the intermediate position of the vehicle width);

Overlap with 25% of adults; overlapping 50% of children;

Overlap with 25% of children, overlap with 75% of adults, and adults are located after 10 feet of children;

Adult is located in the front corner of the driver side;

And 50% overlapping in the plane.

Velodyne laser radar PAEB system (equipped with Velarray laser radar sensor) has successfully stopped five times in all test scenes, and avoided collision.

The vehicles carrying the radar + camera technology PAEB system have failed in each test scenario.
