Simulate Real-World Testing Through LHP's Autonomous Crash Test Dummy

 

LHP, Inc. has entered into a letter of intent (LOI) with Hebei Pride Automotive Technology (Pri-Auto) which was established in September 2019. Together, LHP and Pri-Auto are committed to providing complete solutions for automotive active safety/ autonomous driving closed-field evaluation. 

LHP is now selling autonomous vehicle testing with robotic crash test dummy - more commonly known as crash test dummies - are used in high-precision test environments to measure human injury and vehicle sensor capability in vehicle crashes. 

In addition to ADAS crash test dummies, LHP will also be supporting autonomous crash test equipment such as:

  • Standard roadside object surrogates for road/lane departure
  • Portable and reconfigurable night lighting systems
  • Portable near-field RCS measurement system for surrogate
  • Soft 360 vehicle target 
 

Designed for SAE Testing Standards' Development 

SAE J3234/1 The PriAuto Autonomous Crash Test Dummy was designed and accepted as the basis for the SAE Standard J3234 “Active Safety Roadside Metal Guardrail Surrogate Recommendation.” These Standard states the “design specifications/requirements for metal guardrail surrogates that represent real metal guardrails to the in-vehicle sensors and can be used for performance assessment of such in-vehicle sensing systems in real-world test scenarios/conditions. This document only includes the recommended metal guardrail surrogate characteristics for automotive cameras, LiDARs, and/or radars – SAE.Org

Demo: Autonomous Crash Test Dummy

 

Product Demo: Autonomous truck utilizes radar, LiDAR, and micro-Doppler technology to sense human and object movement in its path, triggering the automotive braking system.

Test Equipment and Product Features

All autonomous crash test dummies use patented advanced “skin” technology and 3D human body models via Toyota funded research to provide human-like RCS characteristics in 360°

The dummies provide LiDAR reflectivity in the range of 45%-58%, meeting the requirements of SAE & ISO specifications.

All dummies use high-precision motor control inside the shoulders and hip joints to generate realistic human-like movements with variable walking speeds from 0.3m/s - 2.5m/s.

The dummies also feature fast set-up time, requiring zero calibration as well as shorter after-crash recovery time, thus being able to withstand repeated impacts.

The fully automated/integrated drive system is in sync with the dummies, allowing multiple modes of operation
