In last week’s in-depth report, we explained why voice technology is getting to technical maturity within a favorable context of electrification; development of active noise cancellation, and the reduction of BSR (buzz, squeak, and rattle) inside vehicles. BSR level reflects the loudness, roughness, sharpness, tonality and fluctuation strength of a sound. Consumer demand for improved…
Seeing Machines, an Australia-based advanced computer vision technology company designing AI-powered operator monitoring systems to improve transport safety, has collaborated with Magna on a rearview mirror demonstrator with inbuilt DMS combining camera, electronics, and mirror technology. In-mirror DMS has been previously covered in DVN-I. The demonstrator melds Magna’s mirror technology, camera design, integration and packaging…
Mark Rakoski is engineering VP at Mitsubishi Electric Automotive America, which recently formed an advanced engineering arm called Filament Labs with Rakoski in charge. He says, “According to NHTSA, more than 94 per cent of accidents are caused by manual errors. We developed the Inca Jay automotive cockpit platform with advanced ADAS features designed to…
Sienna above, test screens below (TCNA images) Last year in the U.S., up to 23 children cooked to death in parked vehicles; a quarter of them got in the car while it wasn’t in use. Toyota Connected North America (TCNA) now presents their Cabin Awareness concept, which uses high-resolution 4D imaging radar to detect occupants…
Osram has presented a DMC concept called Icarus, which demonstrates how such a system mounted in the instrument cluster or A-pillar can be extended. The AMS Osram 3D sensor system provides high-resolution depth maps (<±0.5% depth accuracy at a range of 45-70 cm) using Structured Light. It also uses a depth extraction algorithm. The system…
Peugeot has launched a range of interior accessories for their 308 model, produced solely using additive manufacturing techniques with a flexible polymer material. The accessories are the result of a joint effort by Peugeot’s Design, Product and Research and Development teams and are 3D-printed using the latest HP Multi Jet Fusion (MJF) 3D printing technology.…
The new Hella Slim Light system can indirectly set the scene for the interior and also enable wide-area lighting, such as in the door. The most striking feature of this system is its slim design and light weight. It can be embedded between several layers. The 8-mm system can thus also illuminate previously unused space…
A car, as an orchestra, would have brass and percussion in the engine compartment with strings and woodwinds all over the place. Buzz; squeak; rattle…noise and vibration have always been integral to the automotive dance. Beyond visible and tactile sensations, car interior acoustics—particularly with respect to NVH and BSR—require a particular sense of understanding. While…
Last summer, the Volkswagen Group assimilated Navistar, the last iteration of a longstanding American maker of commercial vehicles (originally International Harvester), and folded it into Traton, a VW subsidiary that is now the world’s largest maker of trucks and buses. Now VW is beginning to transfer their sophisticated C-V2x (cellular vehicle-to-everything) technology to Navistar for…
