某款A3汽车的轮胎试验数据，包括其纵向力、侧向力以及自回正力矩数据。根据这些数据绘制该A3车的轮胎特性曲线。-Tire test data to a subsection A3 car, including its longitudinal force, lateral force and self-aligning torque data. These data are plotted according to the tire characteristic curve A3 car.

基于A3汽车轮胎的经典轮胎魔术公式的建立。-Establish classic magic formula A3 tires car tires based on.

采用经过修改的魔术轮胎公式对A3型汽车进行轮胎特性曲线进行拟合并绘制理论曲线。-Magic tire using a modified formula for A3 cars carry tire characteristic curve proposed merger draw the theoretical curve.
