Research Status of Four-wheel Alignment Parameters on Handling Stability and Interval Mileage Prediction

The correct four-wheel alignment parameters of the vehicle are an important prerequisite for ensuring the good handling stability, fuel economy, safety and other performance. It mainly analyzes the research status of four-wheel alignment parameters on handling stability at home and abroad, expounds the relationship between four-wheel alignment parameters and vehicle performance, analyzes the research progress of four-wheel alignment parameters based on different types of vehicles, and the influence of camber angle and kingpin inclination on steering reversal torque and wheel resistance torque. At the same time, the common optimization direction, optimization content and optimization method of four-wheel alignment parameters based on suspension structure are summarized,then analyzes the general detection method of four-wheel positioning parameters, and the change trend of positioning parameters and interval mileage is predicted by the method of regression equation.
