What Does All-Wheel Steering System Mean?
3 Answers
All-wheel steering system, also known as four-wheel steering system, refers to the rear wheels having similar steering functions as the front wheels. They can not only steer in the same direction as the front wheels but also in the opposite direction. Additional information: I. Main functions of all-wheel steering system: 1. Improve the operational stability of the vehicle during high-speed driving or under lateral wind conditions. 2. Enhance the vehicle's responsiveness to steering inputs across the entire speed range. 3. Improve maneuverability at low speeds and reduce the turning radius of the vehicle, enhancing mobility. II. Classification of all-wheel steering systems: 1. Based on the relationship between the deflection angle of front and rear wheels and vehicle speed, they can be divided into two types: angle-sensing type and speed-sensing type. 2. According to the power form of the wheel deflection actuator, they can be categorized into three types: hydraulic four-wheel steering system, mechanical-hydraulic four-wheel steering system, and electronically controlled four-wheel steering system.
The all-wheel steering system, simply put, allows all four wheels to turn, unlike regular cars where only the front wheels steer. I've driven a car equipped with this system, and it's particularly useful in urban areas—turning radius is much smaller on narrow streets, and parking becomes a one-shot deal, saving a lot of hassle. On highways, the handling is also more stable, with better body balance during turns, making it feel safer. Although it sounds high-tech, driving feels natural, and even beginners can adapt quickly. Maintenance isn't much different—just regular checks on steering components to ensure the system works properly. Overall, it enhances daily driving convenience and enjoyment, especially in crowded city environments.
The All-Wheel Steering system, abbreviated as AWS, is a technology where all wheels participate in steering. Traditional steering only moves the front wheels, but AWS allows the rear wheels to steer as well through electronic or hydraulic control. At low speeds, the rear wheels turn in the opposite direction to the front wheels, reducing the turning radius; at high speeds, they turn in the same direction to enhance stability. I've discussed this in car enthusiast circles—this system is commonly found in sports cars and SUVs, significantly improving handling, such as smoother cornering and reduced body roll. Installation requires a precise control unit, but the results are fantastic, capable of handling various road conditions. During driving, the response is more agile, greatly contributing to overall performance enhancement.
