“…He verified the developed method by comparing the wheel alignment results with the results from the existing method. Jieh-Shian Young has proposed a micro control unit (MCU)-based camber inspection system with a 3-axis accelerometer [10]. He emphasizes the fact that the axes of the accelerometer can be misaligned to the axes of the camber inspection system and, therefore, in his study he proposes the calibration method to amend these axis misalignments.…”

Vehicle wheel alignment inspection is generally carried out using a computer vision-based system. Due to its inspection mechanism using four wheel centers, the computer vision-based system cannot be applied to the wheel alignment inspection of suspension module units. However, when a vehicle suspension module is being developed, there is no complete car ready for wheel alignment inspection even though it is a very important procedure for suspension property tests. This study proposes a novel and efficient way to inspect vehicle wheel alignment for suspension modules. Two laser modules and several mechanical jigs were employed for wheel alignment inspection, allowing the toe and camber angles of the suspension module to be measured. For accurate wheel alignment results, calibration of the laser modules was performed prior to the inspection. This calibration procedure adjusts the yaw and pitch angles of the laser module so that they can be orthogonal to the mounting jig. For the calibration, a novel method of using laser straightness was adopted and, consequently, 0.02 degrees of orthogonality was achieved. The wheel alignment inspection results were determined then verified using a vision system with two cameras. In order to use this vision system, two cameras were used and a new method of modifying the measurement mechanism was developed. According to the verification results, the proposed wheel alignment inspection provided very high measurement accuracy. The wheel alignment inspection mechanism proposed in this study can not only give very reliable results but also provide a cost-efficient method of inspecting the wheel alignment of suspension modules to automakers.

“…When the wheel leans towards the chassis of the car, the wheels are said to possess a negative camber configuration, and vice versa. Camber angle is set to balance traction and wear and is mainly associated with the premature uneven wear of tire as the surface of the tire tread is not entirely in contact with the road due to the negatively or positively tilted angle when viewed from the centerline of a wheel [1]. In another words, the force transferred from the adhesive contact patch area between the tire and the surface of the road affects the natural path of a four-wheeled automotive carcass in the contact area when camber is introduced.…”

The camber angle is one of the wheel alignment properties that is crucial as a slight change to the orientation of the camber angle determines the lifespan of a tire. The stress distribution on the innermost of a tire increase as the positive camber angle is increased, and vice versa, which causes the abnormal uneven premature wear of the tire. This research is done with the main objectives to simulate the performance of tires concerning the camber angle by using the finite element analysis method, and to study the influence of camber angle on different tire tread patterns under two different road conditions, i.e., smooth road and irregular road. Three tire models with different tire tread patterns and two different road conditions are developed using SolidWorks while the investigation of each tire performance is done through ANSYS under static condition in this research. Tire inflation analysis is performed using static structural analysis feature available in ANSYS where the total deformation and equivalent stress are determined based on the specific vertical load applied onto the tire, ignoring any damping effects and inertia. Boundary conditions and other relevant constraints are applied, and then mesh independent test is carried out to all tire models prior to performing the simulation. Based on the simulation results, the maximum total deformation increases as the camber angle increases in both road conditions, while the maximum equivalent stress does not show any trend. It is concluded that tire tread pattern influences the maximum equivalent stress experienced by the tire.

“…There are also vehicle dynamics and adjustments of the wheel characteristic angles needed for this purpose [2]. Wheel camber angles affect the steering stability and controllability of the vehicle; hence, the alignment of the wheels and the vehicle control system poses a significant ENGINEERING MODELLING 35 (2022) 2, 65-89 problem.…”

Estimation of vehicle dynamics, tire wear, and road profile are indispensable prefaces in the development of automobile manufacturing due to the growing demands for vehicle safety, stability, and intelligent control, economic and environmental protection. Thus, vehicle state estimation approaches have captured the great interest of researchers because of the intricacy of vehicle dynamics and stability control systems. Over the last few decades, great enhancement has been accomplished in the theory and experiments for the development of these estimation states. This article provides a comprehensive review of recent advances in vehicle dynamics, tire wear, and road profile estimations. Most relevant and significant models have been reviewed in relation to the vehicle dynamics, roll angle, tire wear, and road profile states. Finally, some suggestions have been pointed out for enhancing the performance of the vehicle dynamics models.
