Radar and Camera Calibration Equipment (ADAS)

ADAS is an advanced driver assistance system, an in-car electronic system that makes it easier for the driver to drive and perform other functions. The emergence of these electronic systems has been driven by laws and trends to reduce the number of accidents on the road. All ADAS systems use automated technology, i. cameras and sensors to detect nearby obstacles, lines and other signal elements to alert the driver and respond accordingly to both the car and the driver.

Most accidents are caused by human error, not necessarily by drivers, but can also be bystanders and third parties. Intelligent driver assistance systems are systems that have been developed and are being developed to automate, adapt and refine vehicle systems to make driving easier, more comfortable and safer. Of course, all this is proven both by research and by obvious statistics that cars driven with ADAS systems are less likely to be involved in accidents.

All of these safety systems are designed to prevent accidents and collisions on the road by introducing the latest technology to alert the driver to problems, implement safety measures in response and, where necessary, automated systems take over control of the vehicle.

All of these systems can alert drivers to potential obstacles, help you stay out of your lane, center your lane, provide navigation assistance, adjust lighting, turn on cruise control, add traffic alerts, and more. And that’s not the end, due to rising industry quality and safety standards, Advanced Driver Assistance Systems (ADAS) are one of the fastest growing segments of automotive electronics.

ADAS systems first appeared almost 50 years ago when wheeled anti-slip systems began to be installed in cars. The early stages of ADAS systems included electronic stability, anti-lock braking, blind spot information systems, lane departure warning.

The sensors used by ADAS are cameras, radars, lasers and ultrasound. They can detect light, heat, pressure and other variables used to monitor the condition of the vehicle. Typically, all of these sensors are located in the front and rear bumpers, side mirrors, vehicle interior, and are installed in the windshields.

What are ADAS systems?

The ADAS covers all warning systems, the specific systems being:

In the vehicle interior:

Lane Departure Warning System

Lane Keeping System

Recognition of road signs

Night vision system

Driver health / condition monitoring

Electric vehicle warning

Descent control

In front of the car:

Parking system

Adaptive and recognizable front light system

Adaptive cruise control system

Pedestrian detection system

Emergency braking system

At the rear of the car:

Rear vision system

Parking system

Rear collision warning system

Car side systems:

Spatial video systems

Blind detection systems

When is ADAS equipment used?

Under normal circumstances, after repairs in the event of an accident, the relevant auxiliary systems must be calibrated, if the vehicle has such systems. If, for example, the front of the car has been damaged in an accident, dismantling or re-installing surveillance components such as cameras, radars and sensors, using radar and camera calibration equipment to recalibrate all auxiliary systems.

For example: ACC (Adaptive Cruise Control) calibration should be performed in the following cases:

Aligned the wheels or adjusted the chassis of the car.

You have replaced the car's front bumper or radiator grille (depending on where the sensor is installed).

You have adjusted the position of the ACC radar sensor on the vehicle body.

ACC radar sensor deflection angle outside the normal range.

You have replaced the adaptive cruise control (ACC) radar sensor control unit.

How to use ADAS equipment correctly?

Park the vehicle on a level and level surface with the front wheels pointing straight and make sure there are no objects in front of the vehicle.

The vehicle coolants and engine oil must be at the recommended level and the fuel tank must be full. There must be no people or extra items inside the vehicle.

Connect the ADAS calibration equipment to the vehicle. Connect the diagnostic tool to the vehicle.

Close the car door.

Adjust the tire pressure to the recommended parameters.

Follow the instructions on the screen of the device you are using. If you use Autel manufacturer's equipment, all instructions are provided visually, so it will be very convenient.

What if ADAS calibration equipment were used on uneven floors?

ADAS calibration procedures must be performed on a level floor. If the existing floor is uneven or sunken, the calibration of the radar and cameras will have a huge error and will be inaccurate. And that will respond when the car takes to the streets, as existing radars will detect poor environmental surveillance. For example, an adaptive cruise control system will malfunction.

What are the requirements for the premises where the calibration will take place?

There must be no foreign objects in the room, at least three meters away from the car.

No external light sources that would create uneven surface shadows.

Some procedures require a bright side light

After what car repair work is it necessary to calibrate the ADAS sensors?

Sensor replacement, repair after an accident, wheel alignment, windshield replacement.

What are ADAS sensors and where are they in the vehicle?

Cameras, sensors, ultrasound, radar and LIDAR are some of the systems used to record driving environment data, they are used when the car is both in motion and stationary. All of these systems constantly check the vehicle's position, pedestrians, road signs, lane, intersections, road and driving conditions. Cameras, sensors, and sensor systems are typically found on the front and rear bumpers, windshield, front grille, and side and rear view mirrors.

What are the different types of ADAS calibration?

Depending on the make and model of the vehicle, a stationary or dynamic calibration procedure is required to complete the calibration of the ADAS sensors (some steps are required for some vehicle types).

Stationary calibration is completed in the existing room and targets and templates simply need to be completed.

Dynamic calibration requires the vehicle to be driven on public roads for some time with a connected ADAS calibration device, such as the Autel MaxiSys series.

How do I know if the radar and camera calibration procedure is running correctly?

The Autel MaxiSys ADAS Calibration Application software provides step-by-step graphical instructions specific to your vehicle model. During the AutoSCAN scan, the Autel device detects the required make and model and then simply follows all the instructions shown.

How to choose the right set of Autel ADAS equipment?

LDW, LKA, ACC (front systems) - LDW kit required.

AVM, RCW, RCA (ambient video / 360 degree video / rear systems) - full set required.

Night vision, radar (blind spots, etc.) - full set required.

What is an ADAS 360 ° camera?

A 360 ° or spatial camera system uses multiple camera images to create a single 360 ​​° view from above (from a bird’s eye view) around. This system is used when the car is parked autonomously.

What is an ADAS radar sensor?

ADAS radar sensors detect stationary and moving objects at different distances around the perimeter of the vehicle. Different ADAS systems use different radar types and frequencies. Ultra Short Range Radars (USRRs) and Short Range Radars (SRRs) provide data for blind spot detection (BSD) and lane departure warning (LCA), while systems, including Adaptive Cruise Control (ACC), use longer range radars.

How to get ADAS software if I work with AUTEL device?

To obtain ADAS calibration software, you can purchase a MaxiSys ADAS tablet or purchase an update to the ADAS calibration software for an existing MaxiSys tablet.
