摘　　要：分析了爆胎汽车的运动特性,分析了转向和制动操作对爆胎汽车运动性能及控制稳定性的影响。提出了通过对非爆胎车轮联合制动的方法对汽车的运动轨迹和速度进行应急控制,降低驾驶员对爆胎汽车的操控难度。该控制方法采用效率载荷半径变化量和效率侧偏角原则实现制动控制力矩的分配,从另外一个角度探讨了对爆胎汽车前期控制的可能性。The vehicle＇s motion characteristics after tire blow-out was analyzed, the effect of vehicle＇s movement performance and control stability was analyzed by steering and brake operation. By emergency controlling of vehicle＇s motion track and velocity, a method blending brake to non-blow-out tire was given, manipulation difficulty was reduced. The method＇s effect is validated through brake control moment distributing by the principle of fluctuation value of efficiency normal load radius and efficiency side slip angle, the possibility of control at early period was discussed from a different view.
