steering ratio

基本解釋

The steering ratio is the ratio of how far you turn the steering wheel to how far the wheels turn.
轉(zhuǎn)向盤的轉(zhuǎn)角與車輪偏轉(zhuǎn)角的比值，稱為轉(zhuǎn)向系的角傳動比。
There are the entire vehicle mass, the position of mass center, cornering stiffness coefficients, steering- system stiffness and steering ratio.
這些基本參數(shù)包括整車質(zhì)量、質(zhì)心位置、前后輪側(cè)偏剛度、后軸側(cè)傾轉(zhuǎn)向系數(shù)以及轉(zhuǎn)向系剛度和傳動比等。
According to vehicle driving conditions active front steering can achieve the desired steering ratio, which meets the flexibility at low speed and stability at high speed.
主動前輪轉(zhuǎn)向可以根據(jù)汽車行駛狀態(tài)實現(xiàn)理想轉(zhuǎn)向傳動比，能同時滿足低速時的靈活性與高速時的穩(wěn)定性要求。

The steering ratio is too slow.

Moreover, it can reportedly "reprogram the steering ratio and amplify the intensity and quickness of the steering response" to keep motorists safe, but there's no word on whether or not a retinal scanner add-on will be available to automatically adjust user preferences depending on which driver hops in the seat.

They knew things about cars that I never wanted to know about, such as torque ratio and the differences between rack and pinion steering vs. worm and roller.

角傳動比
Steer-by-Wire system cuts off the mechanical link between steering wheel and steered wheels,so it can change steering ratio according to vehicle state to improve vehicle handling and stability.
線控轉(zhuǎn)向系統(tǒng)取消了轉(zhuǎn)向盤與轉(zhuǎn)向輪的機械連接,可以根據(jù)車況靈活改變角傳動比以提高汽車的操縱穩(wěn)定性。
