A communication system for facilitating control over a function of a vehicle () comprises a base station () positioned in the vehicle () and a mobile communication unit (). The base station () comprises a first transmitter for transmitting a signal to the mobile communication unit () and a first receiver for receiving a signal from the mobile communication unit (). The base station () is configured to determine a location of the mobile communication unit () relative to the vehicle () and to cause the mobile communication unit () to operate in accordance with a limited-response mode when the location of the communication unit relative to the vehicle () remains substantially unchanged for a predetermined period of time.

Position-based limited-response mode operation in a vehicle communication system

The invention relates to an access unit for communicating with a further access unit to control access to a vehicle. The access unit comprises at least a first transmitter for transmitting a polling signal; and at least a first receiver for receiving an authentication signal from the further access unit in response to the polling signal. At least the first transmitter is a first ultra-wideband transmitter and at least the first receiver is a first ultra-wideband receiver. The invention also relates to a vehicle access system which is a combination of the access and further access units. The invention also relates to methods of operating a vehicle access system and a vehicle access unit.
