Abstract

Over the past number of years, more and more autonomous functions have been introduced into the newest car models by the automotive industry. These functions include electronic stability control, lane centring, left-turn assist, blind-spot monitoring, etc. The primary purpose of these functions is to increase road safety and, to some extent, the driver's comfort. With the increasing number of functions, more and more sensor devices are being installed in cars, increasing the complexity of the intra-vehicle network. Wireless sensor communication o ers promising features that can reduce this complexity, provide more exibility in the sensor placement, and allow for more sensor nodes and bandwidth compared to some existing intra-vehicle networks. However, wireless communication is a ected by the radio propagation environment inside the vehicle, which is a ected by the tight space and the metal enclosure of the car. To understand the e ects of these restrictions, it is necessary to better understand the channel condition inside the vehicle. The objective of this research is to develop a novel empirical path loss model for the 2.4 GHz based IEEE 802.15.4 radio channel within cars. The channel model is developed based on extensive measurements in two compact cars. The model considers two types of wireless links: those between sensors in the vehicle and those towards sensors on the outside of the vehicle.
