Techniques are described for aligning a vehicle to a wireless charger. Wireless communication is performed between at least a first wireless device of the vehicle and at least a second wireless device external to the vehicle. The first wireless device has a stationary position relative to the vehicle. The second wireless device has a stationary position relative to the wireless charger. Based on the wireless communication, a distance between the first and second wireless devices is measured and used to determine the relative position of the vehicle. A trajectory is calculated, based on the relative position of the vehicle, to enable the vehicle to be maneuvered into a charging position in which a charge receiving device of the vehicle is aligned with respect to the wireless charger. In some embodiments, multiple wireless devices on the vehicle or external to the vehicle participate in determining the relative position of the vehicle.
