本SAE推荐实施规程建立了一致的试验程序，用于确定双轴乘用车和轻型卡车的稳态方向控制特性。这些特性包括方向盘角度梯度、参考转向角梯度、侧滑角梯度、车辆侧倾角梯度以及与横向加速度有关的方向盘扭矩梯度。它们还包括横摆速度增益、横向加速度增益和相对于方向盘角度的侧滑角增益。此外，还可以确定特性或临界转速以及前后轮转向符合性。

This SAE Recommended Practice establishes consistent test procedures for determination of steady-state directional control properties for passenger cars and light trucks with two axles. These properties include the steering-wheel angle gradient, reference steer angle gradient, sideslip angle gradient, vehicle roll angle gradient, and steering-wheel torque gradient with respect to lateral acceleration. They also include the yaw velocity gain, lateral acceleration gain, and sideslip angle gain with respect to steering-wheel angle. Additionally, the characteristic or critical speed and the front and rear wheel steer compliances may be determined.
