Development of monitoring system for series HEV bus with touch panel

In this paper, the monitoring strategies for a series hybrid electric vehicle (SHEV) bus are suggested for the optimal operation of powertrain and detection of abnormal conditions during the initial development of hybrid technologies. The monitoring system receives the messages from four control modules in the SHEV bus through a CAN, and then displays the data in the messages on a touch panel. In addition, all gauges and the on/off switching state of a set of telltale lamps are indicated. The monitoring system is implemented by both the 32-bit DSP and touch panel, and it is installed and tested on the real SHEV bus.
