摘要
通过建立二自由度汽车运动模型得到车辆的转弯半径,结合安全制动距离建立弯道计算模型,进而得到车辆弯道行驶时前照车灯自适应调整角度的计算公式。在理论分析的基础上,对车辆转弯时自适应前照灯转角计算模型进行了数值仿真实验。实验表明由该模型计算得到的前照灯转角在标准规定的范围之内,验证了AFS系统模型的合理性,并在自适应前照灯样机平台上进行测试进一步验证了弯道算法的合理性。
The method of calculating the turning radius of vehicle is presented,which is based on two-degrees-offreedom dynamic model of vehicle.Formula of calculating the adaptive adjustment angle of front-lighting of vehicle driving on curve road is further derived.Based on the theoretical analysis,numerical simulations are conducted for the calculating model of AFS.Simulation results show that the calculated values are within the range specified by the standard and AFS modeling presented in the paper is valid.And the test on the prototype platform verifies the validness further.
