The invention provides an extended-range architecture optimization method. The method comprises the following steps: S1, signal acquisition; s2, signal processing, wherein a power system maximum torque calculation module arranged in the vehicle control unit determines the maximum output torque according to the parameters of the driving motor and the driving working condition of the vehicle; a driving request torque module arranged in the vehicle control unit determines a request torque according to the analog accelerator signal; s3, whether the request torque is larger than the maximum output torque or not is judged; S4, whether the request torque is within the allowable range of a battery or not is judged by a battery system capacity protection limiting module; and S5, a vehicle control unit controls a power generation system to work, and insufficient torque is compensated in an auxiliary mode. Coupling control is carried out between a mature three-electric system and a mature fuel oil engine system through the vehicle control unit, original engine control logic is not changed, complex engine calibration development work does not need to be carried out, and the problems that in the background technology, traditional extended-range automobiles are large in development investment and long in period are solved.
本发明提供一种增程式架构优化方法,包括S1、信号采集;S2、信号处理:整车控制器内置的动力系统最大扭矩计算模块根据驱动电机的参数以及车辆所处行驶工况,确定最大输出扭矩;整车控制器内置的驾驶请求扭矩模块根据模拟油门信号,确定请求扭矩;S3、判断请求扭矩是否大于最大输出扭矩:S4、电池系统能力保护限制模块判断请求扭矩是否在电池允许范围内:S5、整车控制器控制发电系统工作,辅助补偿不足扭矩。本发明通过整车控制器在成熟的三电系统和成熟的燃油发动机系统之间耦合控制,不改变原有发动机控制逻辑,无需进行复杂的发动机标定开发工作,解决背景技术中提到的传统的增程式汽车开发投入大及周期长的问题。
