3-axis gyroscope for automotive applications

STMicroelectronics has introduced a world first - the market’s first 3-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100). ST’s A3G4250D gyroscope newest angular-rate sensor aims to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems.

6234 STMicroelectronics has introduced a world first - the market’s first 3-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100).

ST’s A3G4250D gyroscope newest angular-rate sensor aims to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems. ST says that accurate measurements of angular-motion detection with its automotive-qualified gyroscopes will significantly enhance dead-reckoning and/or map-matching capabilities in car navigation and telematics applications, the company claims. In situations when a GPS signal can’t be seen, such as indoors and in urban canyons between tall buildings, dead-reckoning systems compensate for loss of satellite signal by monitoring motion, distance travelled and altitude.

Precise gyroscope readings can also improve map-matching, the process of aligning a sequence of observed user positions with the road network on a digital map, used in a number of applications.

    Cognitive Technologies says its 4D Imaging Radar for self-driving cars carries out vertical scanning without using mechanical components and can detect objects with an accuracy over 97%. The 4D radar is expected to detect the coordinates and speed of the road scene objects as well as their shape during all weather conditions. According to Cognitive, the solution supports SAR (synthetic-aperture radar) technology which is used to build a map of the environment around the vehicle. This technology also all

    A new generation of ITS equipment is helping road authorities get to grips with cycle safety – and not a moment too soon as Colin Sowman discovers. Cyclists - remember them? Apparently not. At least not according to the OECD 2013 report Cycling, Health and Safety which contains the statement: ‘Cyclists are often forgotten in the design of the road traffic system’. Looking through the statistics that exist (each country appears to compile them differently) it is not difficult to see how such a conclusion cou
