7 Step ADAS process for ADAS calibrations. Join us as we highlight the small but noticeable differences when using the right side line.

7 Step ADAS; The importance of the right side line.
Today, I want to demonstrate why we believe the seven-step method is crucial, especially emphasizing the importance of the left side line in every ADAS calibration. We have a 2020 Toyota RAV4 in front of us, and we’ll walk you through the radar alignment and calibration process we performed on this vehicle.
Overview of the Process
Toyota’s documentation, which is easily accessible, typically shows only a center line for calibration. They suggest measuring from the front bumper forward about 3,000 mm. Initially, I set up the center line with a plum bob at the rear and positioned the target in front. After this, I added the left side line and took another measurement.
The Importance of the Left Side Line
There was a noticeable difference between the measurements with and without the left side line. Although the difference was small, it was significant enough to affect the accuracy. Today, I’ll show you the point of calibration, conduct an alignment check, and demonstrate how the left side line enhances precision.
Calibration Steps
- Initial Setup:
- I used a plum bob to create a center line from the rear to the front.
- Positioned the target at 3,000 mm from the front bumper.
- First Measurement:
- Without the left side line, we performed an initial alignment check.
- The result showed a slight deviation, indicating a bias.
- Adding the Left Side Line:
- Incorporated the left side line for better accuracy.
- This additional step helped refine the calibration process.
- Re-evaluation:
- Conducted another alignment check after adding the left side line.
- Observed the difference in precision and accuracy.
Demonstration
Let’s dive into the practical demonstration:
- Initial Check with Center Line Only:
- We used Texas software for confirmation.
- Initial measurement showed a 0.1 deviation after slight adjustments.
- Removed the target and repositioned the center line.
- Adding the Left Side Line:
- Re-measured with the left side line in place.
- Observed the alignment and saw it was more accurate.
- Adjusting for Bias:
- Lifted the line to check for any bias.
- Noted the target was slightly biased towards the driver’s side.
- Adjusted the target to ensure it was perpendicular to the vehicle.
- Final Check:
- Conducted the final alignment check.
- Results showed improved accuracy with the left side line in place.
Conclusion
Using the left side line in the seven-step method significantly improves the accuracy of radar calibrations. While it may seem like a small adjustment, it plays a crucial role in ensuring precise and profitable calibrations.
By implementing these steps, you can enhance your calibration processes, leading to better results and customer satisfaction. If you have any questions or need further assistance, feel free to reach out. Have a great day, everyone!
