Five pillars of ADAS in automotive to ensure safety and connectivity
Applications related to self driving car technology include various state-of-the-art tools that depend on each other.
Pillars of ADAS in automotive that are key to autonomous driving and product differentiation
Speaking of ADAS feature development and software architecture, we’d like to single out five components that are worth in-depth discussion: sensors, processors, software algorithms, mapping solutions, and actuators.
These elements can be roughly grouped into three subsystems responsible for:
- data acquisition and processing
- data fusion and decision-making
- taking action
System-level design for ADAS in automotive
Sensor technologies are at the forefront of ADAS technology
ADAS vision systems and ADAS safety systems require lots of fused sensors to monitor the vehicle’s surroundings and what’s going on inside the car. The most commonly used ADAS sensors today are lidar, radar, and ultrasonic.
Software for self driving cars featuring ultrasonic sensors usually consists of multiple sensors located in the front and rear bumpers and side-view mirrors. They transmit short sound waves and measure the time it takes for them to travel to a target object and return to the receiver.
Short-range and long-range applications of sensor technology
An ADAS safety system can rely on ultrasonic sensor technology for low-speed and short-range applications such as blind spot detection, self-parking, and parking assistance. Radar and lidar are both used by ADAS engineers for object detection, collision prevention, and interaction with traffic management systems.
Still, there are differences between these technologies. Lidar is the best solution for real-time detection, but it’s unpleasantly expensive for mass deployment. Radar sensors, especially long-range ones, are reliable enough and cheaper but lack precision when detecting small objects.
Processors are indispensable for driving automation at any level
Cameras pointed in all directions, radar and lidar sensors, and multiple displays gather and present information to drivers. Computing all of this data requires high-performance processors. And the need for processing power will grow with future ADAS advancements.
The effectiveness of advanced driver assistance systems is measured by the car’s ability to sense, perceive, and react. But without enough processing power, a computer can’t decide how the car should behave in a particular real-time situation on the road. Traditional low-level programming technologies, which require lengthy development and are difficult to maintain, are inappropriate for most ADAS safety systems.
Modern cars have more than 100 microprocessors and up to 100 million lines of code. So OEMs should choose their processors smartly. The task of seasoned engineers for self driving car technology is to build a sophisticated system that will maintain high-speed transfers with increasing amounts of data to analyze the car’s surroundings and act accordingly. Moreover, engineering companies need to tackle the challenge of multicore architectures and high frequencies with low power consumption.
Autonomous Driving & ADAS Software Development
Build adaptable ADAS for safer and more comfortable driving
ADAS algorithms to propel safe and smart driving
The ADAS market is growing rapidly, and so is ADAS algorithm development. A variety of algorithms are powering life-saving systems. Among them, vision and image processing algorithms are real game changers for ADAS feature development.
Visual sensors are the primary type used for driving, which is why computer vision will play a crucial role in autonomous cars. ADAS algorithms use input from cameras and sensors to incorporate environmental elements into self driving car technology. Then the output provided by these algorithms to the actuation system either warns the driver of potential hazards or gives directions to the ADAS on how to act.
Lane departure warning and lane detection systems, adaptive cruise control, headlight control, autonomous emergency braking, collision warning, pedestrian protection – these are just some of the ADAS applications developed using vision and image processing.
Mapping in ADAS technology sets new standards for in-car navigation
Autonomous vehicle navigation in urban environments requires higher accuracy than GPS-based systems can offer. Besides, GPS may fail, causing what would be an ordinary situation in a car with a human driver to turn into a life-threatening situation in a self-driving vehicle. That’s why advanced driver assistance systems should ensure greater precision, increased stability within environments with dynamic obstacles, and the ability to learn and improve maps over time.
Tech startups, established tech providers, and manufacturers are competing and partnering with each other to work out sophisticated mapping algorithms that store and update geographical and infrastructure information. By incorporating these mapping solutions into ADAS vision and ADAS safety systems, location can be pinpointed to centimeters. OEMs can achieve real-time cloud navigation services, environment perception, planning, and decision-making.

Actuators as major enablers of self driving car technology
The actuation system terminates the chain of events controlled by advanced driver assistance systems. It facilitates interactions between a vehicle’s components and takes prompt actions based on computed results.
Through programmed sequences, the actuation ADAS subsystem reacts to the object recognition results, which are processed into commands to control the vehicle. Automatic actuators allow a wide range of operations from visual, acoustic, or haptic warnings to electric power steering, autonomous acceleration, and braking.

Testing ADAS in automotive helps to ensure vehicle safety and convenience
Advanced driver assistance systems aren’t only connected to vehicle components; they’re also closely interconnected. Vision and camera systems, air conditioning systems, and networks of sensors can no longer be tested in isolation. Only testing of ADAS technology in the framework of the entire vehicle will give precise results.
This isn’t the end of the testing challenges, though. There’s one more type of dependency to consider: smart and interconnected external networks such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) systems. The high interdependency of internal and external subsystems makes the testing scope enormous. Only experienced ADAS engineers can cope with it.
In recent years, the automotive industry has made huge steps toward autonomous driving. And advanced driver assistance systems lie at the core of these achievements. Although ADAS features haven’t become mainstream yet, the goal of fully automated driving is no longer a fantasy.
OEMs and Tier 1 suppliers may have difficulties with ADAS feature development, considering current and evolving legislation and the necessity to integrate ADAS technology into existing and new vehicle architectures. These are just some of the issues that force automotive players to seek external partnerships.
