Drive-by-wireless with the eCar demonstrator

Drive-by-wire technology has been gradually adopted by the car companies in recent years to integrate active assistance systems in vehicles to increase comfort and safety. As an alternative to the wired case, we investigate the so-called drive-by-wireless, i.e., using a wireless network to control steering, braking, accelerating, and other functions within an automobile and focus on the discussion of the safety and latency properties of such a system. We use the commercial off-the-shelf ZigBee MSP-EXP430F5438 Development Board for wireless communication and demonstrate our drive-by-wireless prototype on a 4-wheel steering/drive electric vehicle.
