This publication focuses on the characterization of kinetic energy in the engine compartment of road vehicles to supply autonomous wireless sensor systems. For this purpose multi-dimensional acceleration values were recorded at different installation points and an analysis of the usable engine vibration was performed in the time and frequency domains for multiple installation locations and orientations. Additionally, the frequency distribution of occurring engine speeds were investigated in application-oriented driving situations, and the power spectral densities for city, intercity, and highway driving routes were calculated. Through the evaluation of the measured accelerations with the corresponding OBD data of the vehicle it is possible to estimate the amount of harvested energy for different driving routes. The results serve as a basis for the development of an optimally adapted high efficiency energy harvester for several locations in the engine compartment.
