Abstract (en)
[origin: GB2603506A] A control system (1) having one or more controller(s) (21) for communicating with a device (2-n) and configured to broadcast at least a first polling signal (PS-n) to initiate a communication with the device (2-n). The control system (1) receives a response signal (IDS-n) from the device (2-n); and identifies the device (2-n) from the response signal (IDS-n). The control system (1) implements a first polling mode (PM-n) to initiate the communication with the device (2-n); and to implement a second polling mode (PM-n) after identification of the device (2-n). The polling modes preferably have different polling rates, with the first polling rate of the first polling mode greater than the polling rate of the second polling mode. The second polling mode can also include the generation and transmission of a device sleep signal which may be targeted to a particular one of a plurality of identified devices via a device identifier. The second polling mode can also include periodically transmitting the first polling signal. A device wake-up signal can also be generated and transmitted to the device to amplify generation of the response signal. The device is preferably an electronic key to access a vehicle.
