u-blox, provider of leading positioning and wireless communication technologies has announced that Siemens has integrated the former’s ZED-F9K high-precision dead reckoning module into its Toyota Prius V2X (vehicle-to-everything) test fleet. Siemens carried out live demonstrations of the technology at the ITS European Congress 2019 in Eindhoven, the Netherlands. The ZED-F9K turnkey solution minimises the effort required to achieve decimetre-level positioning accuracy in automotive applications, the company noted.
Satellite-based positioning plays a crucial role in advanced driver automation systems and driverless vehicles as the only available source of absolute position. The same is true in V2X communication, in which vehicles continuously share their location and other information with other traffic participants – cars and pedestrians – as well as surrounding infrastructure, improving road safety and reducing traffic congestion.
V2X test vehicles typically determine their position using high-end, expensive GNSS (Global Navigation Satellite Systems) receivers. While these provide highly accurate position information, they fail to realistically represent the hardware that will be deployed in vehicles produced for the mass market, u-blox noted. It said that by opting to use the ZED-F9K turnkey solution for high precision dead reckoning, Siemens was able to align the performance of their test fleet with real-world conditions. It also enabled reduced cost and engineering effort required to develop the vehicles.
Igor Passchier, Engineering fellow, Connected and Automated Driving, Siemens PLM Software, said the company has had a very positive experience with u-blox’s ZED-F9K high precision dead reckoning solution. The product delivered strongly from the initial design-in to the data and performance in the first tests, he added. Passchier noted that this underscores the reputation of u-blox as a trusted innovator in GNSS technology.
The company’s collaboration with Siemens shows the extent to which the ZED-F9K turnkey solution saves OEMs time, cost, and engineering effort, noted Alex Ngi, Product Strategy - Dead Reckoning, Product Centre Positioning, u-blox. “For us, it has also been a welcome opportunity to contribute to solving the challenges in the autonomous driving ecosystem,” Ngi added.
