Setting up ADAS Radar and Camera Calibration
In today's automotive industry, Advanced Driver Assistance Systems (ADAS) play a crucial role in ensuring the safety and efficiency of vehicles. One essential aspect of ADAS is the radar and camera calibration, which ensures the accurate functioning of the system. In this article, we will explore the step-by-step process of setting up the ADAS radar and camera calibration for an Acura vehicle.
1. Introduction
ADAS technology has revolutionized the automotive industry by incorporating advanced safety features and driver assistance functions. However, for these systems to function effectively, accurate calibration is necessary. Calibration ensures that the radar and camera systems are correctly aligned and calibrated to provide precise data for the ADAS system. Proper calibration ensures that the system's calculations and responses are accurate and reliable, thereby enhancing the safety and performance of the vehicle.
2. Setting up the ADAS Radar and Camera Calibration
2.1 Establishing the Center Line
The first step in the ADAS radar and camera calibration process is to establish the center line of the vehicle. This is essential for accurate alignment. Using a plumb bob, the center line can be marked in the front and back of the vehicle. Care must be taken to ensure that the plumb bob remains in the center without falling to either side.
2.2 Taking Measurements from the Front Tires
Once the center line is established, measurements need to be taken from the center of the front tires. This can be done using a Honda tool that allows for easy identification of the tire's center. Marking the center of both front wheels with tape helps in maintaining accuracy throughout the calibration process.
2.3 Stretching out the Center Line
To provide a base for both the front radar and camera calibration, the center line needs to be stretched out and taped ahead of the vehicle. This ensures that the line is visible and runs through the center dot in the vehicle's front.
2.4 Setting up the Front Radar Calibration
For the front radar calibration, specific spots need to be marked on either side of the vehicle at 4000 millimeters. These spots indicate where the front triangle target, necessary for calibrating the front radar sensor, should be placed. The use of green laser lights facilitates accurate marking, ensuring precision calibration.
2.5 Adjusting the Height of the Triangle
To align the front radar properly, the height of the triangle target needs adjustment. Acura recommends placing the cone right in the center. By referencing the center line and the piece of tape marking 4000 millimeters, the cone can be centered and aligned with the vehicle, ensuring accurate calibration.
3. Using the Honda Diagnostic System
The Honda Diagnostic System (HDS) is an essential tool in the ADAS radar and camera calibration process. This system allows technicians to access and perform the necessary adjustments for calibration.
3.1 Accessing the ADAS Section
After logging into the Honda Diagnostic System online and selecting the ADAS menu, technicians can access the radar aiming function. It is important to note that the TDC blinking on the bottom of the screen should not cause concern at this stage.
3.2 Performing the Radar Aiming
Before starting the radar calibration, it is important to remove the target from the calibration setup. The radar scans the area to ensure there are no obstructions or interference before calibration. Once confirmed, the target is placed back in position, aligning it with the center line and the marked spot on the frame. The radar aiming process is quick and accurate, ensuring precise calibration.
3.3 Removing the Target and Starting Calibration
After completing the radar aiming, the next step is to remove the target and begin the calibration process. This involves turning off the ignition, turning it back on, and following the prompts provided by the Honda Diagnostic System. The calibration process ensures that the radar and camera systems are synchronized and accurately calibrated to the vehicle's specifications.
3.4 Completing the Calibration
Upon completing the calibration process, it is essential to turn the ignition off, then on again. This step finalizes the calibration and allows the system to recognize the newly calibrated radar and camera. Once complete, all the buttons on the right side of the steering wheel become operational, allowing for adjustments in distance and the activation of various ADAS functions.
4. Setting up the Front Camera Lane Departure Target
4.1 Using the Same Base as the Radar
The setup for the front camera lane departure target utilizes the same base as the radar calibration. By attaching a taller pole to the base, the camera calibration setup can be achieved.
4.2 Assembling the Calibration Setup
All the necessary parts for the front camera lane departure target are readily available from OEM Honda parts. Assembling the setup involves measuring the distance between the targets and securing them in the predetermined positions.
4.3 Performing the Static Camera Calibration
The camera calibration process consists of both static and dynamic calibrations. The static camera calibration ensures proper alignment of the camera system while the vehicle is stationary. By following the prompts on the Honda Diagnostic System, the camera is calibrated quickly and accurately.
4.4 Performing the Dynamic Camera Calibration
To complete the camera calibration, a dynamic calibration process is necessary. This involves driving the vehicle at a certain speed in appropriate lighting conditions, allowing the camera to learn and calibrate itself to the road's specific markings. Once completed, the camera system is fine-tuned, ensuring optimal performance.
5. Finalizing the Calibration Process
After completing both the radar and camera calibrations, it is essential to shut off the engine, turn it back on, and check for any malfunction lights or alerts. If all the lights indicate successful calibration and the ADAS system functions as expected, the calibration process is considered complete.
6. Conclusion
ADAS radar and camera calibration are vital for the proper functioning of advanced safety systems in modern vehicles. Following the step-by-step procedure outlined in this article ensures accurate alignment and calibration of the radar and camera systems, providing safe and reliable ADAS functionality. It is recommended to consult the manufacturer's guidelines and use the appropriate diagnostic tools for a successful calibration process.
