Ford wheel imbalance detection patent Uses Vibration and Wheel Speed Sensors to Improve Safety
A wheel imbalance can cause uncomfortable vibrations and, if left unaddressed, can lead to costly component failure. That is presumably why Ford has filed a patent for a sophisticated system designed to detect these problems long before a driver might notice them. The Ford wheel imbalance detection patent, published in December 2025, describes a method that could revolutionize tire health monitoring.
The patented system utilizes existing sensors already found in modern cars to provide a precise, data-driven way to identify when a wheel is out of balance. This technology goes beyond simply monitoring tire pressure to actively preserving the lifespan and performance of the vehicle’s tires and suspension.
Here is a look at how the system works and the significant benefits it offers to Ford owners.
How the System Works
The patented system leverages two key data points already collected by the vehicle’s onboard computer, eliminating the need for dedicated, expensive new hardware.
| Sensor Used | Data Collected | Purpose in Detection |
| Wheel Speed Sensors (ABS) | Monitors the rotational speed and instantaneous dynamic rolling radius of each wheel. | Used to compute a sinusoidal function of the wheel’s rotational speed, indicating imbalance. |
| Vibration/Yaw Sensors | Detects excessive vehicle body and steering wheel vibrations. | Data is continuously monitored and compared against thresholds to trigger an alert. |
The processor implements a machine-learning program that continuously monitors these signals. Drivers often “feel” an imbalance through excessive steering wheel vibration (“wheel shimmy”), particularly at highway speeds. This new system analyzes those signals precisely, ensuring early detection when the abnormality is still minor.
Benefits to Vehicle Owners
A wheel balance detection system would work alongside the Tire Pressure Monitoring System (TPMS) as an essential preventative maintenance feature.
- Extends Tire Lifespan: Imbalanced wheels cause uneven tire wear (such as cupping or flat spots), forcing owners to replace tires prematurely. Early detection promotes even wear.
- Improves Safety and Comfort: It eliminates intense vibrations transmitted through the steering wheel and cabin, reducing driver fatigue and improving overall control and stability, especially at higher speeds.
- Reduces Maintenance Costs: Unbalanced wheels transmit stress to connected components like shocks, struts, ball joints, and wheel bearings, accelerating wear and leading to expensive repairs.
The Ford wheel imbalance detection patent signals that the Blue Oval is committed to using software and existing hardware to improve vehicle durability and reduce long-term ownership costs for its customers. While not all patents become production features, the safety and cost-saving benefits of this system make it a feature Ford owners would certainly welcome.
