Today’s average high-end car runs roughly seven times more software code than a Boeing 787. But the typical in-car, embedded, onboard navigation applications in today’s connected car are way out of step with the actual needs of drivers, claims WIRED. “They are expensive and yet are woefully inferior in content and capabilities from what’s on a typical mobile phone. As a result, drivers have increasingly begun to simply use what’s on their smartphones in a cradle or in their hand.”

One of the most important developments is the introduction of an Open Computing Language (OpenCL)-based automotive development environment from Freescale. This will provide auto manufacturers and their suppliers with a faster way to implement a more sophisticated range of Advanced Driver Assistance Systems (ADAS) as soon as 2015. OpenCL is an open, royalty free standard for cross-platform, parallel programming. It is maintained by the non-profit technology consortium Khronos Group.

Standards Development

To get the most out of these safety systems, and to take the next step to autonomous vehicles, standards are required.

One of the more difficult challenges for the growing fleet of connected cars is in the area of cybersecurity and regulatory oversight. In the United States, for example, the National Highway Traffic Safety Administration (NHTSA) recently announced that it may make vehicle-to-vehicle communications mandatory. This could call into question whether OEMs can protect their driver-generated data and keep it proprietary. To deter government regulations, the Alliance of Automobile Manufacturers created a set of standard consumer privacy practices that will go into effect in the model year 2017.

The IEEE is active many key areas: connected vehicles, autonomous and automated vehicles, inter- and intra-vehicle communications, and transportation electrification. Some of the projects include:

The smart grid will allow utilities to integrate electric vehicles. IEEE standard 2030is the “Guide for Smart Grid Interoperability of Information Technology Operation with Energy Technology and the Electric Power System and End-Use Applications and Loads.” This standard provides guidelines in understanding and defining smart-grid interoperability of the electric power system with end-use applications and loads, such as electric vehicles.

Power-line communications are part of intelligent transportation; they allow data to be transmitted over existing power lines. IEEE standard 1901is the “Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications.” It’s for high-speed communication devices that use electric power lines, also known as broadband over power-line devices, which can be used in transportation platform applications. The standard also addresses security to ensure that the communications between users are private.

Networking and communications are obviously crucial to connected vehicles. The well-known IEEE 802 series, which includes the IEEE 802.3Ethernet and IEEE 802.11Wi-Fi standards, is an obvious choice for vehicle connectivity. These proven and broadly adopted standards are being used in ways that may very well go beyond the wildest imaginations of their inventors.

Wireless access in vehicular environments is another key to intelligent transportation. The IEEE 1609series of standards, known as the WAVE standards, addresses the lack of homogeneous communications interfaces between different automotive manufacturers. It also helps solve the lack of ubiquitous high-speed communications between vehicles and service providers.

ISO 15638 addresses “Telematics Applications for Regulated commercial Vehicles (TARV).” According to project leader Bob Williams, “This delivers standards based on the same secure communications that are used for cooperative intelligent transport systems (C-ITS) – harmonized and compatible with such systems. The advantage is that it can use the 2G/3G mobile phone already installed for today’s fleet management systems, it can use the 5.8 GHz technology currently used for electronic toll collection, and it can migrate to LTE/4G communications or use the new dedicated 5.9 GHz technology being developed for C-ITS.”

To ensure that the technologies being developed for vehicles around the world are reliable, IECQ (IEC Quality Assessment System for Electronic Components) has created a program that gives the automotive industry a standardized way of testing the components. IECQ AQP (Automotive Qualification Programme) helps automotive manufacturers avoid multiple tests and related costs. It can also be used by independent, third-party certification bodies to make sure that components meet automotive industry standards.
