Recently, Solid State Relay (SSR) using Power MOSFET or Intelligent Power Switch (IPS) has been increasingly used in automobile industries. Comparing with the mechanical relay, SSR offers relatively higher switching speed and reliability by its non-contact structure and self-protection function. Because of these outstanding features, SSR is often used in engine and safety control systems. A new SSR system for rear lamp control, which can offer higher levels of power line protection against overcurrent than conventional fuses. The SSR system has been developed utilizing Power MOSFET with a built-in overheat protection circuit (PW-MOS), high precision Current Sensing Resistor and newly developed Driver IC. The system functions and verification results on major issues are described as well as the future goals of such SSRs.

This study introduces the most recent version of the Toyota Electro-Multivision system which was equipped on the 1991 Soarer. As in the previous version, the Electro-Multivision is operated and controlled by interactive inputs through touch-activated display panel switches. The key features of the system are its use of the state-of-the art 5.9-inch thin film transistor (TFT) LCD and four improved navigation functions. The new navigation-related functions are as follows: 1. Two CD-ROM disks incorporating map data on major cities (Scale: 10,000 to 1). 2. Touch activated panel display of maps that can be scrolled with the touch of a finger. 3. A location function that works off a global positioning system (GPS) and map matching. 4. Route Guidance from the present position to a target destination.
