Siemens is to use solid-state lidar supplied by XenomatiX to validate its physics-based lidar simulation model.
Simulations play an essential role in the development and testing towards self-driving vehicles and Siemens’ Simcenter Prescan software virtually reproduces real-world traffic scenarios to validate the safety and reliability of advanced driver assistance systems (ADAS) and automated driving (AD) functionalities. Siemens says the partnership will allow it to add a generic, physics-based lidar simulation model to Prescan which will enable it to fine-tune its simulation model and validate it with real-life measurement.
Jordan Gorrochotegui Candamo, product manager at Siemens, commented, “To achieve safe and reliable validations, Siemens needs to provide customers an accurate digital twin of real-life traffic scenarios. Simcenter Prescan allows us to do this while providing high fidelity sensor simulation. XenomatiX is one of the first lidar suppliers to implement a true solid-state unit that will likely make it to production vehicles. This gives us confidence in our choice to validate our simulation with XenomatiX using their XenoLidar product.”
For a simulation model to be useful, it needs to be validated first to ensure its results represent the real world. Without validation, a simulation is useless for virtual design and prototyping. Siemens notes that its physics-based lidar simulation model has been validated by comparing the lidar model behavior with the behavior of physical lidar in multiple circumstances.
