Abstract

A vehicular interface may include an electromechanical interface between a hand-held electronic device and subsystems on a vehicular bus or network. In selected embodiments the interface may operate in a “master mode” when a handheld device, such as a tablet computer or smart-phone, is not inserted therein. In this mode the interface may serve as a master controller and accesses and controls various subsystems on a vehicle (such as engine control subsystems, media controllers, navigation systems, sensors and transducers) as a master controller. In one embodiment, when a tablet device is inserted into the interface, the interface may automatically switch to “slave mode” in which it acts as an adapter or interface between the tablet device and the vehicular subsystems. In this mode of operation the user'"'"'s exclusive interface is through the tablet computer and the tablet computer serves as the master controller for the system.

Claims

1. A maritime vehicular-to-handheld interface system comprising:

a communications network or bus hardwired and communicatively coupled to a plurality of vehicular peripheral devices, the peripheral devices including at least a sonar; and

a dual-mode interface device coupled to the communication network or bus, the interface including an interface processor, housing, user interface, display, power supply means, memory storage means, and means to communicatively couple with a handheld computing device, the memory including instructions which when executed by the interface processor enable the dual-mode interface to switch between at least two operational modes;

i) a slave mode when a handheld computing device is communicatively coupled to the interface, wherein when in a slave mode the interface processor is a peripheral to the handheld computing device, the latter of which serves as a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices, and

ii) a master mode when a handheld computing device is communicatively coupled to the interface, wherein when in the master mode the interface processor is a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices;

wherein the handheld device includes one or more application programs which are configured to receive data from and transmit data to one or more vehicular peripheral devices,

wherein the interface processor receives software updates retrieved by the hand-held computing device from a remote server, and

wherein the housing includes a receptacle to releasably retain and electrically couple the handheld device to the interface processor and power supply means.

2. The system of claim 1, wherein the interface processor receives software updates retrieved by the handheld computing device from a remote server.

3. The system of claim 1, wherein when in the slave mode the handheld processor receives data retrieved by the interface device from a vehicular peripheral device and transmits the data to a remote server.

4. The system of claim 1, wherein the housing further includes means to protect the handheld device from moisture and vibration.

5. The system of claim 1, wherein the peripheral devices further include a sonar and temperature sensor.

6. The system of claim 1, wherein the interface does not include a GPS, Wi-Fi or cellular communication device.

7. The system of claim 1, wherein the clock speed of the interface processor is substantially slower than that of a central processing unit of the handheld computing device.

8. The system of claim 1, wherein the processing speed the interface processor is substantially slower than that of the handheld computing device.

9. The system of claim 1, wherein a memory access speed of the interface device is substantially slower than that of the handheld computing device.

10. The system of claim 1, wherein the user interface is provided via the display.

11. The system of claim 1, wherein the handheld device is a tablet PC or a smart phone.

12. A system comprising:

a plurality of vehicular peripheral devices;

a handheld computing device; and

a master/slave interface device permanently coupled to the plurality of vehicular peripheral devices and selectively coupled to the handheld computing device, the interface including an interface processor, bus, housing, user interface, power supply, memory, and an adaptor to communicatively couple with a handheld computing device, the dual mode interface being configured to operate in at least the following modes;

i) a slave mode when a handheld computing device is communicatively coupled to the interface, wherein when in a slave mode the interface processor is a peripheral to the handheld computing device, the latter of which serves as a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices, and

ii) a master mode when a handheld computing device is communicatively coupled to the interface, wherein when in the master mode the interface processor is a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices;

wherein when in the slave mode the interface processor receives data retrieved by the handheld computing device from a remote server, and

wherein when in the slave mode the handheld processor receives data retrieved by the interface device from a vehicular peripheral device and transmits the data to a remote server.

13. The system of claim 12, wherein the handheld device includes a plurality of application programs which are configured to receive data from and transmit data to one or more vehicular peripheral devices.

14. The system of claim 12, wherein the housing includes a receptacle to releasably retain and electrically couple the handheld device to the interface processor and power supply means.

15. The system of claim 12, wherein the handheld device includes an application program which is configured to receive data from the vehicular peripheral devices.

16. The system of claim 12, wherein updates to an application running on the interface processor are received from the handheld device.

17. The system of claim 12, wherein the handheld device is a tablet PC or a smart phone.

18. The system of claim 12, wherein the housing further includes means to protect the handheld device from moisture, temperature or vibration.

19. The system of claim 12, wherein the handheld computing device includes a plurality of applications each of which access one or more vehicular peripheral devices.

20. The system of claim 12, wherein the processor interface is not configured to run said plurality of programs.

21. The system of claim 12, wherein the interface device does not include a GPS, Wi-Fi or cellular communication device.
