The second element of the solution is test-driven development and automation, a process
in which tests are defined before coding starts and then automatically run after code integra­tion. Software designers and developers—not a separate testing department—refine and iterate the tests during the development process with customers. This approach compels developers to consider how to use a system and how to implement it before coding.

For instance, drivers must now deal with clunky, lag-filled interfaces that are slow to respond to their inputs, since infotainment systems must wait to receive information from other components. There are also disconnects (such as a lack of coordinated information between instrument clusters and center screens on some vehicle models) and an absence of visual consistency for indications and alerts. These issues are not only distracting but also disappointing to consumers accustomed to streamlined, user-friendly interfaces in mobile phones and tablets—devices that cost far less than a car does. Hackers have proved their ability to access locks, brake systems, and dashboard displays remotely via the cloud connections in several models.


That being said, regardless of the scope or pace of the transformation, becoming a prominent player in the SDV arena is recognized as a prerequisite for achieving competitive success. One should also not discount the fact that vehicle self-awareness is about not only revenue generation but also self-healing, as over-the-air (OTA) updates also target preventive fixes significantly reducing cost of quality. The introduction of a standardized, state-of-the-art development toolchain is a key enabler to unlock 30 to 40 percent of productivity potentials from automated testing and agile methods. As with the agile approach, a system-development team can manage and define the interfaces between hardware and software teams to split hardware/software backlogs and ensure synchronization across levels.

The adop­tion rate may be low because automotive applications have very specific requirements that make it difficult to imple­ment a standard agile approach across the organization. Further, the automotive agile tool set must be capable of handling system complexity, the often-complicated interdependencies with hard­ware development, and strict regulatory require­ments con­cerning cybersecurity, vehicle safety, and quality. This approach quickly makes it clear and transparent which changes affect what work products.

Growth in new sensors for electric drives will not be able to offset the decreasing demand for sensors in ICE vehicles, which have higher sensor content per vehicle. Body sensors represent a growing market due to new comfort features and higher demand for existing comfort features—especially in smaller vehicle segments and at nonpremium OEMs. The agile software method also helps OEMs implement new architectures in which processing moves to large, centralized domain controllers from smaller electronic control units, reducing cost and complexity. Agile organizations create small teams called “scrums” in response to specific, high-priority requirements of the business. The teams then engage in a “sprint,” an iterative process of writing code, testing it, gathering feedback from stakeholders, rewriting the code and so forth. In the waterfall approach, software development goes through discrete phases, with one phase being completed before the next begins.

The amount of software code in a modern car is a hundred times larger than the amount of onboard software in an F22 fighter. Moreover, this figure continues to grow with new features appearing in connected cars, and a shift towards self-driving, hybrid and electric vehicles. Car drivers have become users that expect new and updatable features and a digital user experience in addition to driving comfort and safety. OEMs are thus committed to lay the foundations for faster innovation through a concept called Software-Defined Vehicle (SDV).

Areas of strongest growth include software functions (with a CAGR of 11 percent) as well as inte­gration testing (at 12 percent). A leading EV OEM has embarked on this path, designing its electronic systems to share a common software foundation. Nearly all the systems can seamlessly communicate with each other and receive updates over the air.

“Software enhances the driving experience, and above all, it makes drivers’ lives easier,” says Stefan Hartung, chairman of the Mobility Solutions business sector and future CEO of Bosch. For example, they can hand over the irksome task of stop-and-go driving to a traffic jam pilot and in the very near future, electric cars will be able to automatically book the cheapest vacant charging station along the route. Automatic parking makes it possible for vehicles to automatically navigate the parking garage and park themselves. “Turning these solutions into reality requires well written code, connectivity, and artificial intelligence,” explains Hartung. Today’s automotive product development is changing through a scientific and technological revolution in software development, as digital technology and the capabilities of consumer electronics are used increasingly more often. The time is approaching when cars will become part of the Internet of Things and will connect to mobile devices.

This led to the development of specialized software tools and languages, such as MATLAB and Simulink, which were used for designing and testing automotive software. The virtual reality technology has enormous potential in educating future drivers, allowing them to recreate realistic road situations. With the help of this technology, virtual automotive testing and development services will become available. People will be able to simulate a general perception of danger or specific scenarios, for example, to practice emergency driving skills or test reaction speed. Our top-tier SLA-based support and maintenance services are aimed at safeguarding that your business systems and vehicle software operate flawlessly and in line with your needs and expectations.

Perforce static analyzers — Helix QAC and Klocwork — have been trusted for over 30 years to deliver the most accurate and precise results to mission-critical project teams across a variety of industries. You can even configure them to support custom coding rules that are specific to your development team. See how Perforce static analyzers will help you comply with C coding standards C++ coding standards, and other coding standards. Automotive cybersecurity is an essential practice of software development as it helps to ensure that the software is safeguarded against security vulnerabilities.

Automotive-software development: Trapped in a maze of complexity

These players have also found ways to reuse a single software architecture across many types of devices, substantially reducing the need for redesign. A typical new-generation vehicle likely has a software architecture composed of five or more domains, together comprising hundreds of functional components in the car and in the cloud. These cover everything from infotainment automotive software development and ADAS to mapping, telematics, and third-party applications (Exhibit 1). This piecemeal approach is common among industry leaders because no single software platform on the market can meet all cross-system needs. Establishing standardised platforms leads to gradually replacing classic components that feature function-specific, embedded, monolithic software.
