An ADAS and autonomous-driving case study

Zenuity is a small company with a large mission. This startup — launched by Volvo Cars and Veoneer, a subsidiary of automotive safety leader Autoliv — is developing advanced driver-assist systems (ADAS) and autonomous-driving (AD) technologies that promise to take vehicle safety systems to a new level. Zenuity is focused on the software side of the ADAS/AD problem. It enables smarter vehicles with a complete software stack, including algorithms for computer vision, sensor fusion, decision making and vehicle control, along with applications that run in the cloud. AI is at the heart of the Zenuity’s solutions, according to Dennis Nobelius, the company’s CEO. In an interview with  Automotive World , he notes that AI is one of the major trends driving advances in ADAS and AD systems. “We realize that we must be effective with the data that we generate and handle, and AI is really transforming the way we use that data and, therefore, how we operate software,” he says.

Piezoelectric power generation in tires

       The battery range of many electric vehicles is limited, meaning that such methods of transportation can only be used for short trips. However, in extended-range electric vehicles or plug-in hybrids, manufacturers include an internal combustion engine that uses conventional fuels to recharge batteries in motion and, hence, extend their range. 1   Although practical, this approach defies the purpose of having an electrical driveline: to reduce environmental impact through the use of renewable energy sources. The need remains for a cleaner power-generation technique that allows maximum range extension with minimal environmental consequences.        Piezoelectric materials generate electrical energy when subjected to mechanical strain. Power-generation devices based on such materials have surfaced in recent years in the context of vibrational-energy harvesting. 2   However, their output has only been sufficient to power sensors...
