Whether to do four-wheel alignment or not, finally there’s no need to worry anymore

After changing the tire, many people may be a bit conflicted about whether to do four-wheel alignment or dynamic balancing. The answer is actually very simple: change the tire to perform dynamic balancing; Perform four-wheel alignment only when running off track. The truth is, it's not today's theme. Today we will talk about four-wheel alignment.

After we buy a car, we all encounter a situation where the new car's direction is in the right direction and the car also goes in a straight line. However, as the car is driven for a long time, the steering wheel becomes increasingly misaligned, the car always tilts in one direction, making it difficult to grip the steering wheel, and the wear and tear of the four wheels is also different. There are many factors that can cause problems, such as frequent use of bumpy roads, high-speed impact on speed bumps, replacement of vehicle suspension components, and so on. However, these issues are difficult to attract the driver's attention in the early stages of occurrence, and only become aware when the feedback is obvious.

What methods are there to let drivers know the problem in the first place? Just like a tire pressure warning. Recently, General Motors has applied for a detection system for automatic wheel alignment, which may be able to meet practical needs. The patented technology uses an IMU (Inertial Measurement Unit) to detect whether the wheels are misaligned. When the force applied to the vehicle is between two predetermined values, the system will remind the driver whether to check the wheels.

After confirming the inspection, the system will automatically set a data table for testing the vehicle's straight-line driving and display it to the driver through the HUD head up display. During testing, the IMU, sensors, and camera work together. When the wheels exceed the preset values, the system will display the set standard route and offset angle data for the driver's reference. At the same time, it will remind the driver again whether it is necessary to go offline for inspection and repair in a timely manner. Next, if necessary, the system will search for the nearest repair shop through intelligent internet connection and preset the navigation.READ MORE!!
