Eco Drive indicating system lets driver know whether car is operating in fuel-efficient state or not, so that the driver is guided to save fuel. Eco Drive state is distinguished based on A/T shift pattern data, engine operating status, transmission operating status. With Eco Drive indicating system, it was proved that fuel-efficiency can be increased by 4~26%.

An embedded system requires test process for reality of the system. For this, it is important to test exception handling which programmer developed. Especially, embedded system is required to test input from hardware device and external signal. But, manual test is required much time and low reality. And it is hard to reproduce faulty situation for debugging. In this paper, we propose a new exception handling test criteria for an embedded system. For this criteria, we define exception type and test exception handling using fault injection technique. And we propose generation of test data for occurring exception situation.

The exchange of messages, shared memory, and a pipe for efficient Inter-Process Communication between various software components are used. We have researched the test automation method that find IPC defects and discover faults location automatically. The test automation method called AMOS v3.0-IPC that is used for evaluation of CAR-Infotainment software.

The main goal of standardization on diagnostic specification is to achieve the reusability of diagnostic program. Reusability is connected with the reliability and cost reduction including delivery time. DIMS was developed to attain these goals through reducing the efforts for standardization verification and coding works. The XML-based database structure and auto-generation method of DIMS enable these features. As a result, through DIMS, the reliable diagnostic program can be obtained cost-efficiently in an early stage.

A control method of Speed variant power window system is used motor speed control as profiles. we can reduce a crashing sound from window’s top and detect Anti-pinch through motor speed control. In addition a suggested system improve system reliability depending on using learned value that can be monitored the motor characteristic changes or the friction force changes of glass rubber etc.
