What is the function of variable steering ratio?

[SanClayton]

The functions of variable steering ratio are: 1. It can reduce the number of steering wheel turns; 2. It enables the car to achieve better steering performance at low speeds; 3. It provides better maneuverability and stability; 4. It refers to adjusting the steering gear ratio based on the car's speed and steering angle; 5. When the car is in a parking state, at low speed, or with a large steering angle, it provides a small steering gear ratio; 6. When the car is driving at high speed or with a small steering angle, it provides a large steering gear ratio. Variable steering ratio is divided into: mechanical variable steering ratio system and electronic variable steering ratio system.

Variable steering ratio is a pretty cool automotive steering feature that automatically adjusts the ratio between the steering wheel's turning angle and the wheels' steering angle based on vehicle speed. At low speeds, such as when navigating tight urban corners or parking, the system reduces the ratio—just a slight turn of the wheel results in a significant wheel angle change, making parking effortless without constant back-and-forth adjustments. On highways, like during long-distance drives or high-speed cruising, the ratio increases, making the steering feel more stable—requiring more wheel input for minor adjustments, ensuring the car stays steady without wobbling or losing control from small movements. This is primarily achieved through an electric power steering system that senses speed changes and adjusts in real-time, working alongside stability control to enhance safety. I've tested several cars with this feature, like certain BMW or Toyota models, and the driving experience feels more intuitive and secure, especially in harsh weather or on winding mountain roads. Overall, it significantly improves handling comfort, making it easier for both beginners and experienced drivers to handle diverse driving scenarios.

After driving for a long time, I particularly appreciate the variable steering ratio design. At low speeds when parking, the steering wheel feels light and effortless, allowing the car to turn flexibly with just a slight turn, unlike older cars that required a lot of force to steer. On the highway, the steering wheel becomes heavier, providing a stable grip and keeping the car running straight, reducing the risk of dangerous misoperations. In real-world driving, I've experienced its benefits in city turns and highway lane changes, especially on slippery roads where it minimizes the chance of skidding. Some cars integrate this feature with ADAS systems, making handling more intelligent and safer. I think this is a thoughtful function in modern cars and highly recommend it to frequent drivers.

As someone who prioritizes driving safety, I value the variable steering ratio function because it helps reduce accident risks. The agile steering at low speeds aids in quickly avoiding pedestrians and obstacles, while the steady feel at high speeds prevents oversteer or loss of control during turns. The electronic system monitors vehicle speed in real-time to adjust the ratio, improving reaction time in emergencies. Combined with the vehicle stability program, it optimizes traction, making driving more controllable and reassuring.
