摘　　要：控制精度是汽车电子点火控制系统所追求的目标,而控制策略的数学模型又是其根本。讨论了基于最小二乘法的汽车电子点火控制策略,探讨了控制系统开发中数据存储方案,提出了离线控制模型建立的相关算法和在线实时点火控制的查找算法。通过试验验证了该系统的可行性和可靠性,并表明动力性和经济性指标取得明显改进。Controlling precision is the pursuing goal of car electronic ignition control system. The mathematic model of control strategy is its fundament, The strategy of ignition control based on method of minimum square is elaborated. The data storage scheme of applying this strategy to develop control system is deeply discussed. The fitting points-searching during ottline fitting, the creating of curving surface-fitting equation coefficient, and the search algorithm of curving surface in online real-time ignition are presented. The feasibility and reliability of this system are validated through experimentation. The evident amelioration of dynamics and economics are achieved.
