MODEL-BASED SOFTWARE DEVELOPMENT IN PRODUCTIONAPPLICATIONS WITH A CLOSED-LOOP CONTROLLED LOCKUPCLUTCH IN A ZF 6-SPEED AUTOMATIC TRANSMISSION

摘要

Despite shorter development times and increasing requirements on thesoftware, software quality and customer satisfaction must be maintained or even increasedwithout increasing cost. In order to shorten product development time, it is necessary toparallel and decouple mechanical, electronic, and software development. Test beds forpossible simulations are necessary for parallel and independent software development. Themaintenance cost can be reduced by reusing simulation models in various test beds. If testsare shifted to earlier phases, then the development cost is reduced. The use of models incontrol unit functions enables new functionalities and can reduce the development cost. Hereit is important to develop simple processes for preparing model parameters. The model-basedprocess and its achieved benefit will be demonstrated using the example of the softwaredevelopment for transmission controls.
