Qualcomm Technologies Inc., a subsidiary of Qualcomm Incorporated, is working with TomTom on using the Qualcomm Drive Data Platform for high-definition (HD) map crowdsourcing for autonomous driving. Qualcomm Drive Data Platform collects and analyzes data from different vehicle sensors, supporting smarter vehicles to determine their location, monitor and learn driving patterns, perceive their surroundings, and share this perception with the rest... read more

UC Riverside team developing non-GPS nav system for autonomous vehicles

October 13, 2016By

A team of researchers at the University of California, Riverside has developed a highly reliable and accurate navigation system that exploits existing environmental signals such as cellular and Wi-Fi, rather than GPS. The technology can be used as a standalone alternative to GPS, or complement current GPS-based systems to enable highly reliable, consistent, and tamper-proof navigation. The technology could be... read more

Low-cost precise positioning for automated vehicles

gps-hud-PRINT-O

Carrier-phase differential GNSS produces mass-market centimeter accuracy A dense reference network facilitates low-cost carrier-phase differential GNSS positioning with rapid integer-ambiguity resolution. This could enable precise lane-keeping for automated vehicles in all weather conditions. Strong demand for low-cost precise positioning exists in the mass market. Carrier-phase differential GNSS (CDGNSS) positioning, accurate to within a few centimeters even on a moving platform,... read more

Recent progress with Dedicated Short Range Communications (DSRC) Notice of Proposed Rule Making (NPRM) brings connected cars or V2X — connectivity between vehicles, infrastructure and all road users — closer to reality than ever before. If all goes well, an NHTSA mandate on DSRC in new light vehicles is expected to start around 2020 as a phase-in plan, with completion... read more

Automotive nagivation suite.

Context-dependent scan matching for aided navigation By Jyh-Ching Juang, Shang-Lin Yu and Shun-Hung Chen Context-dependent scan matching for aided navigation — finding the rotation and translation that best align two consecutive scans — provides laser-ranging data that can be blended into a GNSS navigation system. A quality index based on analysis of intra-frame point clouds assesses the scan context, accounting for variations... read more

KVH looks to self-driving cars with inertial sensor plans

April 6, 2016By
KVH’s high-precision FOG is key to a driverless car’s performance. In this photo, the red illumination represents light moving through the FOG’s optical circuit of coiled fiber; this circuit is the FOG’s sensing unit — it is mounted with power and processing electronics within a driverless car to provide precise data for the car’s navigation systems.

KVH Industries is developing a fiber optic gyro (FOG)-based, low-cost inertial sensor for self-driving cars. The company also released a Developer’s Kit to assist design engineers with integrating FOG technology into driverless car control systems. FOGs and FOG-based inertial measurement units (IMUs) are key parts of the sensor mechanisms that are essential for highly accurate autonomous car performance, KVH said.... read more
