“…46,47 It is seen that AC system operation resulted in a 20-25% increase in the fuel used over the Federal Testing Procedure (FTP) driving cycle. Measured power consumption values for automotive AC systems have also been reported, 45,[48][49][50] indicating that the AC compressor typically absorbed up to 4 kW, which in turn means a fuel consumption of up to 0.5 l/100 km.…”

In response to the current and future energy and environment challenges, the automotive industry is strongly focusing on improving the fuel efficiency of vehicles. Although the electrification of automotive powertrains is clearly the principal path towards sustainable transportation, many opportunities still exist to improve the fuel economy of conventional vehicles. However, some of the technical solutions representing the state of the art in research and advanced development are difficult to benchmark in terms of their potential benefits for fuel consumption improvement. A greater understanding of the fuel energy utilization on the vehicle (here intended as a ‘system’ ) is therefore necessary in order to identify the readily available opportunities for efficiency improvements and, ultimately, to develop automobiles which are more fuel efficient. To this extent, this paper presents a review of the state of the art and technology trends in the field of energy management and recovery for automotive systems, with the primary focus on conventional powertrains. An understanding of the fuel energy utilization and dissipation associated with the vehicle subsystems (the engine, transmission, and chassis) is provided, as well as an overview of the opportunities and potential challenges in improving the fuel economy through system-level energy management, recovery, and harvesting. Finally, an overview of the most important solutions for managing energy dissipation, energy recovery, and harvesting is presented, discussing their potential for fuel economy improvement, technical readiness, and challenges. Wherever possible, projections on fuel economy improvements, based on either experimental data or simulations, are reported to provide opportunity for the assessment and comparison of current and future technologies.

With an increase in the number of electrical systems installed in vehicles, the wire harness design has become increasingly complicated and, accordingly, it has become essential that it is validated. Simulation is a good method of validation but it requires models of the installed electrical systems as well as wire harness design tools to support the simulation function. An electronic control unit (ECU) is a particularly important electrical system because it is connected to many other electrical systems through the wire harness and controls their operations. In this study, a method for modelling ECUs is developed, using the Capital Harness system design tool. The model parameters of the ECU are categorized into system parameters, external parameters, network parameters, and power parameters. The electrical structure of an ECU is built on the basis of the types and default states of the parameters. The behaviour of the ECU is defined in terms of simplified combinational logics in a state-machine-based structure since the target of the modelling is to simulate the logical connection conformity of the wire harness. A power-seat ECU model is developed, using the proposed method, and the feasibility of the simulation for wire harness validation is described.
