摘　　要：针对手动变速器赛车手动换挡会在一定程度上影响驾驶员比赛成绩的问题,研究开发手动变速器自动换挡系统,即自动换挡手动变速器。系统包括2个特别设计的重要程序:自动换挡程序、自动油门程序。仿真结果表明:自动换挡程序能够在1挡到4挡之间完美切换挡位,并与转速参数为500 RPM的比赛模式和300 RPM的效率模式相匹配;自动油门程序能够按照特定值降低功率输出转速值,从而使得换挡过程正确、平稳,实现自动换挡程序和自动油门程序完美协同工作。此外,自动油门程序能够精确读取并记忆“加速行为”或加速度输入值的变化率,使用该参数可以在不需要人工干涉油门的情况下改变加油量。该研究及后续实验的成果可能会对特定应用场景的汽车技术产生积极影响。Aiming at the problem that manual shifting in manual transmission racing will affect the driver’s performance to a certain extent,the automatic shifting system of manual transmission,namely automatic shifting manual transmission,is researched and developed.The system includes two specially designed important programs:automatic shift program and automatic accelerator program.The simulation results show that the automatic gear shifting program can perfectly shift gears from first gear to fourth gear,and it matches the race mode with the speed parameter of 500 RPM and the efficiency mode with the speed parameter of 300 RPM.The automatic accelerator program can reduce the power output speed value according to a specific value,so that the shift process is correct and stable,and the automatic shift program and the automatic accelerator program work together perfectly.In addition,the automatic accelerator program can accurately read and memorize the“acceleration behavior”or the change rate of the acceleration input value.With this parameter,the fuel volume can be changed without manual interference with the accelerator.The results of this research and subsequent experiments may have a positive impact on automotive technology in specific application scenarios.
