What does variable gear ratio steering mean?

Variable gear ratio steering refers to adjusting the steering gear ratio based on the vehicle speed and steering angle. The introduction and classification of variable gear ratio steering are as follows: Introduction to variable gear ratio steering: It adjusts the steering gear ratio according to the vehicle speed and steering angle. When the vehicle is parked, moving at low speed, or making large steering angles, it provides a smaller steering gear ratio. Conversely, when the vehicle is traveling at high speed or making small steering angles, it provides a larger steering gear ratio, thereby improving the stability of the vehicle's steering. Classification of variable steering ratio systems: Variable steering ratio systems are divided into two types: mechanical and electronic. Mechanical variable steering ratio systems offer higher reliability, better durability, and a simpler structure. Electronic variable steering ratio systems combine mechanical structures with electronic systems, further enhancing performance.
Variable gear ratio steering is a new feature in steering systems, and after years of driving experience, I find it quite practical. Simply put, the angle of the steering wheel's rotation and the angle of the wheels' turning are not fixed—it automatically adjusts based on speed and driving conditions. At low speeds, such as when parking or making a U-turn, a small turn of the steering wheel results in a larger turn of the wheels, making the operation effortless and reducing stress for novice drivers. At high speeds, the steering becomes 'slower,' requiring more steering wheel input for minor adjustments, which enhances stability and prevents sudden turns that could lead to loss of control. This is achieved through an electronic control system working in tandem with traditional mechanical components, improving driving flexibility. Having driven a car equipped with this feature, I noticed quicker responses in congested urban areas and reduced fatigue on highways, making the overall driving experience safer and smarter.
As an average car owner, I've personally experienced variable gear ratio steering. Imagine this: when making a left turn at a city traffic light, just a light touch on the wheel gets the job done, with the wheels turning quickly, making parking and U-turns effortless. On the highway, the steering wheel feels 'heavier,' providing stable steering where you need to turn it a few more times to keep the car running straight, reducing the chance of drifting. This technology is achieved through changing gear ratios, automatically adjusting based on different speeds to enhance daily convenience. I find it particularly useful for family cars, reducing stress when picking up kids or on long trips, and lowering the risk of accidental turns. While it's not high-tech, it makes driving more user-friendly, and I recommend considering this feature when buying a new car.
From a safety perspective, variable gear ratio steering is crucial. I understand that it adjusts steering sensitivity at different speeds—enhancing responsiveness at low speeds to avoid obstacles and reducing sensitivity at high speeds to improve stability. For example, during sharp turns, the system prevents oversteering, reducing the risk of skidding accidents. Compared to fixed-ratio steering, it intelligently adjusts and combines with electronic assistance to make handling more predictable. In my high-speed experience, it feels safer, especially in rain or snow, preventing instability. Daily urban driving also benefits, with smoother and more natural turns.
