摘　　要：尽管动力换档无级变速变速器已成为拖拉机传动系统的标准配置。作为竞争的结果,如同无级变速器那样动力换档变速器已经为用户尽可能的扩展功能和特性。动力换档变速器大部分的进步来源于采用创新性的电控系统。这也增加了控制单元的复杂性和与CAN通信网络的联接结构。为进一步满足用户在电控系统安全性和适应性方面近乎苛刻的要求,开发过程必须不断修改和优化。ZF集团内部所拥有的在汽车应用方面的经验和硬件-软件开发过程工具也能有效地应用于农业机械中。Despite of the success of infinitely variable transmissions powershift transmissions predominate as a standard tractor drive train. As a result of the competition development efforts on powershift transmis- sions have been increased with the target to cover as many as possible functions and features known to be a customer benefit of infinitely variable transmissions. Most of the improvements on powershift transmissions are based on the use of advanced innovative e- lectronic controls. This lead to increasingly complex control units and architectures linked together by com- munication networks CAN. In order to keep pace with more demanding customer requirements in terms of safety and serviceability of electronic controls, development processes need to be revised and optimized permanently. Experiences as well as tools regarding the whole hard-and software development process that exists inside the ZF group from automotive applications for a long time are also used effectively in agricultural applications.
