An LCD instrument panel, which displays a vehicle’s speed, an engine revolution, a fuel level and a coolant temperature, in digital or bargraph form on a single, large area LCD, has been developed. In adapting electronic items to the instrument panel, a single chip 8-bit microcomputer which manages most of the signal processing with excellent software techniques, a specially designed LCD driver IC and some hybrid-ICs have been employed. In this way, a minimised electronic assembly and a very suitable display were designed so that mass-production became possible.

A new liquid crystal display module integrating a LC cell of reflective type, printed circuits and a driver IC on a piece of plastic (polyethersulfone) is developed for automotive dashboard instrumentation. The module, which includes an LC cell with 22 leads to display, can be interfaced directly to a microprocessor with only 8 external leads. The module is flexible so that compact assembly with the systems is possible.

This paper describes the onboard data acquisition system for truck and bus which has been developed by Mitsubishi Electric Corp. and Mitsubishi Motors Corp. This system, which is called MCVOCS (Mitsubishi Commercial Vehicle Operation Control System), records various vehicle operating data and provides much valuable information for both a driver and a fleet owner. For example, it may serve for fuel economy and effective operational management. The main purpose of this paper is to describe the system configuration and the data acquisition software of the system.

This paper presents an example of a centralized remote control system for car audio equipment. We present the way by which all car audio equipment except the operation switches and the display can be removed from the drivers site. The ploblems and technology to achieve this remote control system are described. Especially the division methode of the car audio system and the various data transmission technology between separate units are described.
