基于虚拟仿真技术的“电控发动机”教学案例研究

Teaching case study of“Electronic control engine”based on virtual simulation technology

目前高职院校汽车发动机电控技术课程在教学中存在理论教学效果不良、实训难开展等问题,虚拟仿真技术作为新的教学手段具有许多优良的特点,为解决发动机电控技术的教学困境提供了好的途径。以理论抽象、实践性强的“汽车点火系统的检修”为例,通过虚拟仿真点火电路的学习,使得抽象的电学知识以具体化、可视化的形式展现给学生,加深了学生对于理论的理解;同时通过模拟操作,可以规范实践检修的流程,提高学生的实践技能。此外,虚拟仿真技术的应用研究也为汽车电控类课程教学改革提供了可参考的典型案例。

At present, there are problems in the teaching of automotive engine electronic control technology courses in higher vocational colleges, such as poor theoretical teaching effects and difficult training, as a new teaching method, virtual simulation technology has many excellent characteristics, provides a good way to solve the teaching dilemma of engine electronic control technology. Take “overhaul of automobile ignition system” with theoretical abstraction and strong practicality as an example, through the study of the virtual simulation ignition circuit, the abstract electrical knowledge is presented to the students in a concrete and visual form, which deepens the students’ understanding of the theory;at the same time, through simulation operation, the process of practical maintenance can be standardized and the practical skills of students can be improved. In addition, the application research of virtual simulation technology also provides reference typical cases for the teaching reform of automotive electronic control courses.
