Abstract:
Electric bus energy consumption is mainly due to the vehicle traction. Additionally, auxiliary systems such as cabin heating-cooling, air compressor, and power steering consume energy. One way to optimize the consumption is a Driver’s Aid System (DAS). Based on the route information, DAS provides the driver the optimal driving suggestions, and simultaneously may optimise the energy use of auxiliary systems. These approaches are discussed in the paper. When the optimal air compressor operation was introduced, vehicle energy consumption was decreased 1.6 %. In addition to guiding the auxiliary devices and the driver, prospects of using DAS as a communication hub for managing buses, their charging and to share information for a bus operator are discussed.
