High-performance Inertial Navigation Systems for self-driving cars

Self-driving cars, also known as autonomous vehicles or driveless cars, are vehicles equipped with advanced sensors that allow them to navigate and operate with limited to no human intervention. These cars rely on a combination of technologies such Inertial Navigation Systems (INS), LiDARs, radars, cameras, and GNSS to perceive their environment, make decisions, and move safely and efficiently through various traffic conditions.
The goal is to improve road safety, reduce traffic congestion, and enhance mobility and comfort for all, including those who may be unable to drive.

Enhancing autonomous cars navigation

Our Inertial Navigation Systems (INS) provides real-time roll, pitch, and heading, integrated with a GNSS receiver to maintain accuracy in case of signal outages (buildings, trees, tunnel, etc.).
Inertial sensors are also used to precisely synchronize and stabilize additional equipment such as LiDAR or Camera for a driverless car application.
The integration of an INS with other sensors helps create a comprehensive understanding of the vehicle’s environment, enabling it to navigate complex and dynamic scenarios with greater precision.

Improving safety and reliability of self driving vehicles

One of the most challenging environments for self-driving cars is urban areas, where GNSS signals can be obstructed by tall buildings, and traffic conditions can change rapidly. INS provides the accuracy and reliability needed to navigate these environments safely.
Our INS sensors use Micro-Electro-Mechanical Systems (MEMS) technology. This allows smaller, more accurate, and more power-efficient sensors, enhancing the overall performance of INS in autonomous cars.

“Collaborating with SBG Systems and integrating the Ellipse-D into our vehicle has been essential in achieving the precision and reliability critical to our R&D efforts and autonomous operations.”
Oguzhan Saglam, Sales Manager
Unmanned Solution
“We need ultra-high precision. Because the vehicle is driving on the road, we usually need centimeter-level accuracy. The accuracy of the IMU is very important because the vehicle sometimes loses its GNSS signal, such as an environment like a tunnel.”

How self-driving cars work?

Self-driving cars are vehicles equipped with sophisticated systems that enable them to navigate and control themselves without human intervention. These vehicles use a combination of autonomous driving sensors and algorithms to perceive their environment, make decisions, and perform self driving tasks. The goal is to achieve full autonomy, where the vehicle can handle all aspects of driving safely and efficiently.

 

Self-driving cars rely on an array of key technologies to perceive their surroundings. These include:

 

  • GNSS (Global Navigation Satellite System): to get the real-time updates on the self-driving car position, speed, and direction.
  • INS (Inertial Navigation Systems): to maintain accuracy in case of GNSS signal outages. It provides real-time updates on the self driving car position, speed, and direction.
  • LiDAR (Light Detection and Ranging): use of laser beams to create a detailed 3D map of the vehicle’s environment. This technology helps the car detect and measure objects around it, including other vehicles, pedestrians, and road signs.
  • Radar (Radio Detection and Ranging): use of radio waves to detect the speed, distance, and direction of objects. Radar is particularly useful in adverse weather conditions and for detecting objects at longer ranges.
  • Cameras: to capture visual information about the vehicle’s environment, including lane markings, traffic signals, and road signs. They are essential for interpreting complex visual cues and making decisions based on visual data.

What is the difference between ADAS in cars and self-driving cars?

ADAS (Advanced Driver Assistance Systems) enhances driving safety by providing features like lane-keeping, adaptive cruise control, and automatic braking, but requires active driver supervision. In contrast, self-driving cars, equipped with autonomous driving systems, aim to fully automate vehicle operation without human intervention.

 

While ADAS supports drivers by assisting with tasks and improving safety, self-driving cars are designed to handle all aspects of autonomous driving, from navigation to decision-making, offering a higher level of automation (SAE levels) and convenience. ADAS characteristics or features are attributed to SAE levels below 3 and self-driving cars as such correspond to minimum level 4.
