The explosion of technological advancements and automation in the automotive industry boosted the demand for safety systems in vehicles. Advanced Driving Assistance Systems (ADAS) refers to active and passive safety systems aiming at preventing or minimizing car accidents on the road, mainly caused by human error.

What is ADAS?

Advanced Driving Assistance Systems (ADAS) can be defined as electronic technologies used in vehicles to improve safety and driving comfort. ADAS technologies mainly use sensors and cameras to help the driver with routine operations:

  • Assistance in parking
  • Pedestrian detection
  • Lane departure warning
  • Blind-spot detection

Valeo’s ADAS systems

Valeo developed innovative technologies and automated systems to increase safety and reaction times to potential dangers on the road.

Active and passive safety ADAS systems include:

Valeo’s ADAS equips new vehicles across all markets

Driving assistance systems (ADAS) are essential technologies for guaranteeing the safety of passengers and other road users. They are rapidly becoming widespread: by 2030, they will equip 90% of all vehicles sold worldwide. The market is expected to grow exponentially to reach 120 billion euros in value in 2035 (x8).

The world number 1 in driving assistance systems, Valeo already equips 1/3 of new vehicles sold across all markets. This strong position results from a systemic and transdisciplinary approach. Today, Valeo owns the most comprehensive product portfolio required for producing the complete architecture of adavanced driving assistance systems (ADAS): sensors, cameras, advanced software, artificial intelligence (AI) or even cyber-security.

ADAS make vehicles safer and smarter

To ensure the safety of passengers and gradually pave the way for autonomous driving, vehicles are increasingly offering ADAS functions – from automatic emergency braking in the event of danger, to monitoring driver alertness, maintaining the vehicle in the correct lane, adapting speed automatically or adjustable lighting. To better understand the environment in which the vehicle operates, and to make safe driving autonomous, Valeo is focusing its strategy on the research and development of sensors that can be integrated into the vehicle, to become its ‘eyes and ears’.

ADAS : the benefits of a comprehensive approach

ADAS sensors and cameras

A pioneer in driving assistance systems, Valeo developed its first ADAS sensors in the 1990s, initially to provide parking assistance. The portfolio then gradually extended to include other functions. Today, driving assistance systems include a multitude of sensors produced on a large scale: ultrasonic, radar cameras or even the first mass-produced automotive LiDAR (Light Detection and Ranging).

These ADAS sensors allow the vehicle to acutely perceive its surroundings, making driving safer and easier. Other Valeo innovations include the 360 Vue® multi-camera system, which can detect obstacles around the vehicle during manoeuvers and parking, while the rain-lighting-humidity sensor activates and automatically adjusts several functions by measuring the volume of precipitation and the level of ambient light.

ADAS software

Beyond ADAS sensors, Valeo is also fast becoming the leader in the rapidly growing domain controller market. These supercomputers aggregate all the vehicle software, thus ensuring the operation of the entire ADAS system.

Finally, in the field of software, Valeo is developing the perception layers for all its sensors and cameras, state-of-the-art computer vision algorithms for its surround cameras, complete parking and low-speed manoeuvering software solutions, as well as safety, assisted driving and partial automation functions.

Level 3

To meet strict legal requirements in terms of safety standards (UN R157), the first Level 3 autonomy cars in the world (Mercedes-Benz S-Class and the Honda Legend) are equipped with Valeo’s LiDARs.


Valeo has already produced some 1.5 billion sensors of all types over the past 30 years and its production forecasts stand at 1.5 billion for the next 5 years.

More and more sensors – and ADAS software!

The consistent development of software is essential to proper ADAS functioning. For example: a medium-haul aircraft requires around 17 million lines of code to operate. A premium vehicle requires more than 70 million!

In the next 5 years, 30% of premium models will be equipped with Level 3 autonomy function. In parallel to the production of the first driving assistance sensors, Valeo, since the 1990s, began developing the full software suite required to control these functions. Today, 40% of Valeo’s R&D engineers, around 6,000 people, are dedicated to the development of our systems and software. Valeo is also part of a vast ecosystem, notably through strategic partnerships with major players such as AWS, GitHub, Autosar, Qualcomm, Nvidia or Mobileye.

Valeo is also an integration and validation partner for its customers. In 2025, 3 out of 4 cars will be equipped with Level 1, 2 and 3 of autonomy technologies. Thanks to its Drive4U demonstration car, Valeo now has a complete system capable of reaching Level 4 autonomy.
