Drivetrain simulation using variational autoencoders

arXiv.org Artificial Intelligence

This work proposes variational autoencoders (VAEs) to predict a vehicle's jerk from a given torque demand, addressing the limitations of sparse real-world datasets. Specifically, we implement unconditional and conditional VAEs to generate jerk signals that integrate features from different drivetrain scenarios. The VAEs are trained on experimental data collected from two variants of a fully electric SUV, which differ in maximum torque delivery and drivetrain configuration. New meaningful jerk signals are generated within an engineering context through the interpretation of the VAE's latent space. A performance comparison with baseline physics-based and hybrid models confirms the effectiveness of the VAEs. We show that VAEs bypass the need for exhaustive manual system parametrization while maintaining physical plausibility by conditioning data generation on specific inputs.


Near Field iToF LIDAR Depth Improvement from Limited Number of Shots

arXiv.org Artificial Intelligence

Indirect Time of Flight LiDARs can indirectly calculate the scene's depth from the phase shift angle between transmitted and received laser signals with amplitudes modulated at a predefined frequency. Unfortunately, this method generates ambiguity in calculated depth when the phase shift angle value exceeds $2\pi$. Current state-of-the-art methods use raw samples generated using two distinct modulation frequencies to overcome this ambiguity problem. However, this comes at the cost of increasing laser components' stress and raising their temperature, which reduces their lifetime and increases power consumption. In our work, we study two different methods to recover the entire depth range of the LiDAR using fewer raw data sample shots from a single modulation frequency with the support of sensor's gray scale output to reduce the laser components' stress and power consumption.


Porsche Consulting partners with TUM to create applications for artificial intelligence

#artificialintelligence

Porsche Consulting has entered a strategic partnership with UnternehmerTUM, the Center for Innovation and Business Creation at the Technical University in Munich, to create applications for artificial intelligence. In collaboration with established companies, start-ups, and scientists, the management consultancy wants to advance the use of artificial intelligence in actual practice. To this end, the appliedAI initiative has now been launched in Munich. With this appliedAI partnership, the management consultancy is expanding its own range of services offered in the fields of analytics and artificial intelligence. Teams made up of consultants and AI experts will support the projects from conception to the test run.
