Introducing a real-world environment simulation system for autonomous driving/ADAS sensor evaluation. The system can reproduce actual rainfall and fog environments and quantitatively and efficiently evaluate the effects on sensors.
Challenges in Autonomous Driving/ADAS Sensor Evaluation
The performance of external recognition sensors is affected not only by the actual complex traffic and road environment, but also by the weather-related environment, such as unspecified rain, fog, backlighting, and shadows. On the other hand, autonomous driving/ADAS requires defining its operating range, and it is necessary to identify performance limits, including sensor performance.
There is a need for a simulation device that can quantitatively and efficiently evaluate these performance limits.
Focusing on environmental recognition performance in bad weather conditions such as rainfall; we worked with the customer to develop a facility that can reproduce rainfall conditions on public roads and evaluate sensor recognition performance during actual vehicle operation in an actual rainfall environment.
This facility is divided into two main parts:
1. Environmental simulator capable of reproducing fog and rain (five levels)
We have delivered rainfall equipment that can reproduce rainfall ranging from fog to rain to torrential rain (20~100mm/h). Rather than simply spraying water, we are also focused on reproducing actual raindrops.

2. Steerable 4-wheel constant velocity bench to activate autonomous driving/ADAS
The 4-wheel constant velocity bench (video available) is a device that can be placed on a platform in actual driving conditions in order to operate autonomous driving/ADAS. It is capable of high-speed driving (up to 130 km/h) and lane change steering (steering angle of about 45°, but can be equivalent to full steering when the vehicle is stopped).

Verification of sensing performance during rainfall using this facility
We propose the most suitable equipment and provides system-up engineering to solve your problems and concerns.
Combining the expertise in evaluation equipment that we have accumulated over many years of providing exhaust gas evaluation equipment and the extensive engineering expertise of HORIBA MIRA, we are able to work together with our customers to find solutions to their problems and propose optimal evaluation equipment.
We also perform system upgrades for evaluation equipment that were previously handled by the customer, allowing the customer to concentrate on their core business, such as evaluation and verification.
We help customers to define, design, build, test and validate their connected and autonomous vehicles during the complete development life cycle.
