Abstract

In this work we present an Onboard-Unit for sensing critical and uneconomical driveability of buses. Especially old buses can be upgraded with the Onboard-Unit to monitor and inform the bus driver about his driveability. The driver can adapt his driveability to improve the vehicle safety and reduce the fuel consumption. Since CAN-Bus access is often not available in old buses wireless measurement unit such as GPS and the rotational measurement unit are used to measure the bus velocity and the rotational speed of the engine respectively. Furthermore a laser scanner measures the distance to the vehicle ahead. The sensor peripheries and the components for the Onboard-Unit are analyzed and selected for easy installation. The Onboard-Unit logs the sensor data and creates a driver profile. The bus operator can monitor the real time driveability of the bus on a web interface connected to the Onboard-Unit through a GSM-Module.
