Control method and apparatus for controlling operation of an access control device for a vehicle
The present disclosure relates to a controller ( 20 ) for controlling operation of an access control device ( 2 ) for a vehicle ( 3 ). The access control device ( 2 ) is selectively operable in a first operating mode (P 1 ) and a second operating mode (P 2 ). The access control device ( 2 ) is in a limited response mode when operating in the first operating mode (P 1 ). The controller ( 20 ) includes a processor ( 24 ) and a memory means ( 23 ). The processor ( 24 ) is configured to determine a position of the access control device ( 2 ) and to generate a control signal for activating the first operating mode (P 1 ). The control signal is generated in dependence on the determined position of the access control device ( 2 ). The controller ( 20 ) may be provided in the access control device ( 2 ). The present disclosure also relates to a method of controlling operation of an access control device ( 2 ).
1. A controller for controlling operation of an access control device for a vehicle, the access control device being selectively operable in a first operating mode and a second operating mode, the access control device being in a limited response mode when operating in the first operating mode, the controller comprising a processor and a memory means, the processor being configured to:
determine a position of the access control device; and
generate a control signal for activating the first operating mode, the control signal being generated in dependence on the determined position of the access control device; and
identify when the access control device is located in a low usage position where expected usage of the access control device is low, the expected usage of the access control device being predicted in dependence on historic usage of the access control device in a particular position.
2. A controller as claimed in claim 1 , wherein the processor is configured to identify when the access control device is positioned within a designated area; and to generate the control signal for activating the first operating mode in dependence on identification that the access control device is positioned within the designated area.
3. A controller as claimed in claim 2 , wherein the processor is configured to identify the designated area by:
recording a first time when the access control device is substantially stationary and optionally not in communication with the vehicle;
recording a second time when the access control device is actuated;
determining a time period elapsed between said first and second times; and
identifying the designated area as the position of the access control device between said first and second times when the time period is greater than a predefined time period.
4. A controller as claimed in claim 2 , wherein the processor is configured to identify one or more position of the access control device when the access control device is actuated; and optionally also determining an actuation rate of the access control device at a given position; the processor being configured optionally to identify the designated area by identifying one or more position where the actuation rate of the access control device is less than a predefined actuation threshold.
5. A controller as claimed in claim 2 , wherein the processor is configured to generate the control signal in dependence on determination that the access control device has been dormant for a predetermined period of time.
6. A controller as claimed in claim 5 , wherein, when the access control device is positioned inside the designated area, the predetermined period of time is a first dormant time; and, when the access control device is positioned outside the designated area, the predetermined period of time is a second dormant time; the second dormant time being longer than the first dormant time.
7. A controller as claimed in claim 2 , wherein the processor is configured to identify the designated area by identifying a position where the access control device switches from the second operating mode to the first operating mode on a predetermined number of occasions.
8. A controller as claimed in claim 1 , wherein the processor is configured to vary a dormant time before generating the control signal in dependence on a historic actuation rate of the access control device at a current position.
9. An access control device comprising the controller as claimed in claim 1 .
10. An access control system comprising the access control device as claimed in claim 9 .
11. A method of controlling operation of an access control device which is selectively operable in a first operating mode and a second operating mode, the access control device being in a limited response mode when operating in the first operating mode, the method comprising:
determining a position of the access control device; and
generating a control signal for activating the first operating mode, the control signal being generated in dependence on the determined position of the access control device; and
identifying when the access control device is located in a low usage position where expected usage of the access control device is low, the expected usage of the access control device being predicted in dependence on historic usage of the access control device in a particular position.
12. A method as claimed in claim 11 , comprising:
identifying when the access control device is positioned within a designated area; and
activating the first operating mode upon identification that the access control device is positioned within the designated area.
13. A method as claimed in claim 12 , comprising identifying the designated area by:
recording a first time when the access control device is substantially stationary and optionally not in communication with the vehicle;
recording a second time when the access control device is actuated;
determining a time period elapsed between said first and second times; and
identifying the designated area as the position of the access control device between said first and second times when the time period is greater than a predefined time period.
14. A method as claimed in claim 12 , comprising identifying one or more position of the access control device when the access control device is actuated; and determining an actuation rate of the access control device at a given position.
15. A method as claimed in claim 14 , comprising identifying the designated area by identifying an area where the actuation rate of the access control device is less than a predefined actuation threshold.
16. A method as claimed in claim 12 , comprising activating the first operating mode in dependence on determination that the access control device has been dormant for a predetermined period of time.
17. A method as claimed in claim 16 , wherein, when the access control device is positioned inside the designated area, the predetermined period of time is a first dormant time; and, when the access control device is positioned outside the designated area, the predetermined period of time is a second dormant time; the second dormant time being longer than the first dormant time.
18. A method as claimed in claim 12 , comprising identifying the designated area by identifying a position where the access control device switches from the second operating mode to the first operating mode on a predetermined number of occasions.
19. A method as claimed in claim 11 , comprising varying a dormant time before generating the control signal in dependence on a historic actuation rate for a current position of the access control device.
20. A non-transitory computer-readable medium having a set of instructions stored therein which, when executed, cause a processor to perform the method claimed in claim 11 .
