Increasing Role of Software in Vehicles

Learn about the growing role of software in the car, and how it’s changing vehicles with connectivity, OTA updates, ADAS and software-defined architecture.

Increasing Role of Software in Vehicles

The modern car is no longer a mechanical machine, it is fast becoming a software driven device on wheels. Software now controls so much of how vehicles operate—from infotainment and navigation to safety systems and performance tuning.

Software integration can change the driving experience — a fact proven by automakers such as Tesla, Inc., BMW Group and Mercedes-Benz Group. This is a path being taken by many Indian manufacturers with their latest models.

This transition is popularly referred to as the shift towards software-defined vehicles (SDVs) – and it’s one of the biggest automotive trends this decade.

What is a “Software Defined Vehicle” Mean?

A software-defined vehicle is a car where the core functions are controlled, upgraded and improved through software, rather than just hardware changes. In the old days, adding a feature was a matter of changing physical bits. Today, updates can bring lots of features.

Examples are:

• Touchscreen multimedia systems
• Voice assistants
• Advanced Driver Assistance Systems (ADAS)
• Remote diagnostics
• OTA (over the air) upgrades

Software-Defined Cars from Hardware-Centric

Traditional cars were built around mechanical parts. Modern vehicles, however, depend on:

• Electronic Control Unit (ECU)
• Sensors and cameras
• Mainframe Computers
• Cloud connection

This allows cars to be more like smartphones that can get better with time.

Over-the-Air (OTA) Updates: Changing The Game

OTA updates allow manufacturers to push software updates directly to the car without it needing to visit a service center.

The advantages are:

• Bug fixes and performance improvements.
• Further features added after purchase.
• New maps and navigation
• Better battery management in EVs

This will keep the car up to date for years.

Vehicle Security (ADAS) and Software

ADAS features are very software dependent. Systems such as:

• Lane-keeping assist
• Cruise control with adaptive features
• Autonomous emergency brake
• Blind spot detection

They all use sensors, cameras and real-time software processing to prevent accidents and help drivers.

Connected Cars and Intelligent Features

Software allows cars to connect to the internet and smartphones. Drivers may:

• Remote lock/unlock cars
• track vehicle positions
• apps to check fuel/battery status
• Get maintenance alerts

This connectivity adds to the convenience and ownership experience.

The Function of Artificial Intelligence AI

AI is more and more used in vehicles for:

• Speech recognition software
• Driver behaviour analysis
• Predictive maintenance
• Intelligent Traffic Pattern Based Navigation

AI helps cars learn and adjust to the way users behave.

Effect on Electric Vehicles (Increasing Role of Software in Vehicles)

EVs are even more dependent on software than petrol/diesel cars. Battery, regenerative braking, range optimisation and charge control are handled by the software.

Better software means better EV performance.

Benefits to Car Owners (Increasing Role of Software in Vehicles)

The increasing importance of software gives:

• Post-purchase continuous improvement
• Better safety and driving support
• Customized driving experience
• Less service visits
• Longer lifespan of vehicles

Issues of Software Integration

But there are challenges, despite the benefits:

• Information security risks (hacking issues)
• Software bugs and performance problems
• Requirement for regular updates
• Skilled technicians required

Manufacturers are heavily investing in secure automotive software systems.

Predictions for the Future

“Over the next decade:

• Cars will have supercomputers in a central location
• Features can be unlocked by subscribing
• Software will account for 90% of autonomous driving
• Smart cities will fully integrate vehicles

Software will be at the heart of automotive innovation.

Implications for buyers

When you buy a new car, software capabilities will matter as much as engine power. Buyers will be looking at:

• Screen interface quality
• Support news
• Linked features
• ADAS functionality

SUMMARY

The automotive industry is seeing a big shift as software plays a bigger role in cars. Software innovation is making cars smarter, safer and more adaptable.

As this trend takes shape, the future of vehicles will be less about brute force and more about digital smarts.
