Operating system support for ADAS and autonomous vehicle advances

April 22, 2015 // By Graham Prophet
Wind River has introduced Automotive Profile for VxWorks, which is AUTOSAR-compliant software to help customers develop ISO 26262 certifiable automotive safety-critical applications such as advanced driver assist systems (ADAS) to piloted and autonomous driving.

As software-driven applications become more prevalent in vehicles, Wind River says, keeping automotive systems secure and tamper-proof is important for vehicle and occupant safety. For example, through partitioning, companies can consolidate multiple vehicle controls with different levels of safety criticality onto a single hardware platform while maintaining their time- and space-based separation and isolation. This introduces the potential for reductions in cost and weight in vehicles, and may help mitigate risk of attack or interference to other software components all without compromising vehicle safety or functional performance.

Automotive Profile for VxWorks expands the latest version of the VxWorks real-time operating system (RTOS) to help address the growing needs for safe, secure, and certifiable software-driven ADAS and autonomous driving applications.

Key features include;

• Safety partitioning capabilities that can help you build products that are ISO 26262-certifiable up to ASIL D consolidation of multiple applications with different levels of safety criticality onto a single hardware platform.

• Security capabilities for the connected car, such as secure boot to help mitigate the risk of tampering or execution of unauthorised code and access and malicious attacks.

• Streamlined AUTOSAR integration to support standardised connectivity and functional interfaces, enabling simpler and faster interoperability and integration.

• Support for consolidation of a large number of software-driven functions on a smaller number of more powerful electronic control units (ECUs) to help lower costs, space, weight, and power consumption.

“The future of the automotive experience can only come to life by relying on advanced software platforms. Vehicle functions are converging within the car to form a seamless interconnected experience that ties the driver to the world around them. In this complex scenario, the role of software systems is more important than ever,” said Michael Krutz, senior vice president of automotive solutions at Wind River. “Drawing from our technology heritage and expertise in industries such as aerospace and defence, our new automotive offering ...[will]... enable this transformation in
