Software architecture for the ECU of automated manual transmission

To improve the cost-efficiency during the processes of software development and maintenance for the Electronic Control Unit (ECU) of automated manual transmissions (AMT), a software architecture as well as its supporting environments for the ECU of AMT was put forward based on the requirements analysis of AMT system. The software architecture has a structure with five layers and two bases, which consists of a data collection and processing layer, a communication layer, a decision-making and scheduling layer, a harmonization layer, a driving and control layer, an integrated information base, and a knowledge base. The supporting environments include an interface between driver and AMT ECU (transmission control unit, TCU), a display interface, other in-vehicle ECUs, a portable vehicle information online monitoring system, a shift schedule making platform, experts experience, etc. The proposed software architecture has been applied to an AMT test vehicle successfully.
