Abstract

A disclosed system includes a mobile application operative on a mobile device to receive user selected options for limiting drive access to a vehicle when the user is not physically present with the vehicle but wishes to allow service personnel access and limited drive functions. The disclosed system allows user selection of the options, then generates an instruction set for controlling one or more drive capabilities of the vehicle based at least in part on the user selected options. The system establishes an encrypted channel between the mobile device and a telematics control unit of the vehicle. The system controls drive capabilities of the vehicle via the encrypted channel such that the mobile application user can provide remote access for locking, unlocking, ignition, and further restrict drive functions based on time, date, distance, geo-fence options, and other criteria.

First claim

That which is claimed is:

1. A method, comprising:
receiving, via a user interface of a mobile device, user selected options for limiting drive access to a vehicle;
generating, based at least in part on the user selected options, an instruction set for controlling one or more drive capabilities of the vehicle;
establishing an encrypted channel between the mobile device and a vehicle telematics control unit; and
controlling the one or more drive capabilities of the vehicle via the encrypted channel, wherein the instruction set causes the vehicle telematics control unit to change the one or more drive capabilities, wherein the drive capabilities are associated with a time limitation, a distance limitation, a steering limitation and a speed limitation.

2. The method according to claim 1 , wherein the mobile device provides the driving access to the vehicle from a location remote from the vehicle.

3. The method according to claim 1 , wherein controlling the one or more drive capabilities of the vehicle comprises locking and unlocking one or more vehicle lock mechanisms via the vehicle telematics control unit.

4. The method according to claim 3 , wherein the vehicle lock mechanisms comprise an ignition key lock-out actuator, a trunk lock actuator, and a door lock actuator.

5. The method according to claim 1 , wherein the instruction set comprises control rules for controlling one or more of an acceleration actuator and a steering actuator, wherein the control rules limit a speed at which the vehicle is capable of being driven and a distance over which the vehicle is capable of being driven.

6. The method according to claim 1 , wherein receiving the user selected options for limiting drive access to the vehicle comprises:
presenting one or more selectable access options of a plurality of selectable access options via a user interface, the plurality of selectable access options comprising:
a door lock control option;
a trunk hatch control option;
a glove box lock control option; and
an onboard computer control access option; and

receiving user input data associated with a selected one of the one or more selectable access options.

7. The method of claim 1 , wherein receiving the user selected options for limiting drive access to the vehicle comprises:
presenting a plurality of selectable drive capability options to a user via a user interface, the plurality of selectable drive capability options comprising:
an ignition control option;
a speed limitation option;
a steering control option; and
a gear limitation option; and

receiving data associated with user selection of the one or more drive capability options.

8. The method according to claim 1 , wherein the instruction set causes the vehicle telematics control unit to limit a driving distance permitted during a predetermined time frame.

9. The method according to claim 1 , wherein receiving the user selected options for limiting drive access comprises:
outputting a map of a geographic region on the user interface of the mobile device; and
receiving a user input indicative of a user-selected geo-fenced area, wherein the geo-fenced area establishes an outer limit for operating the vehicle.

10. The method according to claim 9 , further comprising generating instructions for limiting driving of the vehicle to operation within the geo-fenced area based on the instruction set, wherein the instructions for limiting driving causes the vehicle telematics control unit to perform one or more acts comprising:
disabling an ignition key lock-out actuator;
disabling an acceleration actuator; and
disabling a door lock actuator.

11. A system, comprising:
one or more actuators for controlling operation of a vehicle; and
a telematics control unit comprising a processor configured to:
establish an encrypted wireless channel between a mobile device and the telematics control unit;
receive, from the mobile device via the encrypted wireless channel, an instruction set indicative of vehicle drive capability settings based at least in part on one or more user selected options for vehicle control or access; and
instruct, based at least in part on the instruction set, the one or more vehicle actuators to limit:
a driving distance;
a driving time;
a geographic region in which the vehicle is capable of being driven;
an amount of steering control; and
a maximum driving speed.

12. The system according to claim 11 , wherein the vehicle actuators comprise one or more mechanisms for vehicle access comprising:
a door lock actuator;
a trunk hatch actuator; and
a glove box lock actuator.

13. The system according to claim 11 , wherein the vehicle actuators comprise one or more actuators for vehicle operation comprising:
an ignition control actuator;
an acceleration actuator;
a steering control actuator; and
a drive gear controller.

14. The system according to claim 11 , wherein limiting the geographic region in which the vehicle is capable of being driven comprises:
accessing a global positioning system (GPS) system to retrieve a GPS coordinate set associated with a current position of the vehicle;
determining that the GPS coordinate set is not a member of a set of coordinates associated with a boundary of the geographic region in which the vehicle is capable of being driven; and
controlling a drive function responsive to determining that the GPS coordinate set is not a member of the set of coordinates associated with the geographic region in which the vehicle may be driven.

15. A computer-implemented method comprising:
establishing an encrypted channel between with a mobile device using a telematics control unit associated with a vehicle;
receiving, via the encrypted channel and based at least in part on one or more user selected options, an instruction set indicative of vehicle drive capability settings; and
changing, based at least in part on the instruction set, one or more drive capabilities of the vehicle, wherein changing the one or more drive capabilities comprises:
limiting a driving distance;
limiting a driving time;
limiting a geographic region in which the vehicle is capable of being driven;
limiting an amount of steering control; and
limiting a maximum driving speed.

16. The computer-implemented method of claim 15 , wherein limiting the driving distance comprises:
accessing a global positioning system (GPS) system to retrieve a coordinate set associated with a current position of the vehicle;
determining that the GPS coordinate set is not a member of a set of coordinates associated with a boundary of the geographic region in which the vehicle is capable of being driven; and
responsive to determining that the GPS coordinate set is not a member of the set of coordinates associated with the geographic region in which the vehicle may be driven:
transmitting a signal to an acceleration actuator that changes a vehicle speed.

17. The computer-implemented method of claim 16 , wherein limiting the driving distance further comprises:
transmitting a signal to an ignition key lock-out actuator that disables the ignition key lock-out actuator.

18. The computer-implemented method of claim 15 , further comprising changing one or more vehicle access options comprising one or more of:
allowing entry to the vehicle using a door lock actuator;
allowing access to a locked trunk storage compartment using a trunk hatch actuator; and
allowing access to a locked glove box storage compartment using glove box lock actuator.
