Abstract

Programmable telematics systems, methods and apparatus for two-way transmission of data and information between fleet vehicles and a fleet management system. The systems and methods employ a programmable telematics communications unit (TCU) configured to connect to the OBD II port of a vehicle, enabling two-way transmission of data and information between a fleet management system and vehicles in the fleet. The TCU device includes cellular data connectivity enabling communication with the management system through existing cellular telephone networks. The programmable TCU may be toggled between multiple operating modes, wherein the TCU provides different functionality, such that a single vehicle may participate in multiple vehicle programs at different points in time, including separate vehicle rental and vehicle sharing programs.

1. A system for controlling the operational mode of vehicles in a vehicle fleet, comprising:

a plurality of fleet vehicles, each vehicle with a make and model each including a telematics control unit, said telematics control unit including a processor to execute computer readable code embedded on a tangible, non-transitory computer readable storage medium, a connection to the OBD II port of the vehicle to enable the control unit to receive vehicle sensor data and actuate a plurality of vehicle devices, a connection to a vehicle access device, and a cellular modem enabling transmission of vehicle data and receipt of programming via cellular networks;

wherein each telematics control unit is programmed for proper operation for the specific make and model of the vehicle in which it is installed;

further wherein each telematics control unit is programmed with at least one of a plurality of available vehicle operational modes, said plurality of vehicle modes comprising a vehicle rental mode and a vehicle sharing mode, wherein at least some vehicle operations permitted or prohibited by the telematics control unit while in vehicle rental mode differ from operations permitted or prohibited, respectively, while in vehicle sharing mode;

a fleet management system including a processor for receiving data from fleet vehicle telematics control units, associating each telematics unit and the data received therefrom with a specific fleet vehicle, and if the telematics vehicle specific programming on a particular telematics control unit does not match the make and model of the specific vehicle, transmitting vehicle specific programming matching the make and model of the specific vehicle to the associated particular telematics control unit;

an application module associated with the fleet management system enabling the remote selection of a desired vehicle operational mode for a particular telematics control unit in a particular fleet vehicle from said plurality of available vehicle operational modes, wherein selection of a vehicle operational mode different from the vehicle operational mode with which the particular telematics control unit is programmed causes the fleet management system to transmit new programming associated with the selected operational mode from the management system to the particular telematics control unit in the selected fleet vehicle, such that, after transmission of the new programming, the selected vehicle and its particular telematics control unit may be operated in accordance with such selected operational mode without removal of the particular telematics control unit from the selected vehicle.

2. The system of claim 1 wherein the available operational modes include at least two of a vehicle rental mode, a vehicle sharing mode, a corporate fleet mode, and a municipal fleet mode.

3. The system of claim 1 wherein a selected fleet vehicle may be remotely switched from one vehicle operational mode to another by the fleet management system in response to user demand.

4. The system of claim 1 wherein a selected fleet vehicle is remotely switched from one vehicle operational mode to another in response to a command input to the selected vehicle via an access card or wireless device and transmitted to the management system by the selected vehicle telematics control unit.

5. The system of claim 1 wherein the telematics control unit further includes one or more sensors or systems for generating data for transmission to the management system, said sensors or systems selected from the group consisting of an accelerometer, and an incline measurement device.

6. The system of claim 1 wherein the telematics control unit further includes an RF modem and chipset for short range communications such that the telematics control unit can communicate with a mobile device.

7. The system of claim 6 wherein one of more of the plurality of vehicle operational modes enable the telematics control unit to unlock or lock a vehicle in response to an authorized Bluetooth command received via the RF modem of the telematics control unit.

8. The system of claim 1 wherein the vehicle device actuations include one or more of door lock, door unlock, vehicle lights on, vehicle lights off, horn activation, alarm activation, starter disabled, and starter enabled.

9. The system of claim 1 wherein the telematics control unit is connected to the access control device via a wired or wireless connection separate from the OBD II connection.

10. The system of claim 9 wherein the access control device is a card reader and the telematics control unit actuates the vehicle doors locks.

11. The system of claim 1 wherein the connection to the OBD II port is a wired connection and includes means for sensing whether the wire is connected to the said port.

12. A method for controlling the operational mode of individual vehicles in a vehicle fleet via a programmable telematics device installed in each fleet vehicle, comprising the steps of:

providing cellular data communication between a telematics control unit installed in each fleet vehicle and a fleet management system, said telematics control unit including a processor, computer memory, a connection to the vehicle OBD II port, a connection to a vehicle access control device, and a modem and chipset for providing said cellular communication capability, wherein said telematics control unit is programmed for proper operation for the specific make and model of the vehicle in which it is installed, and further wherein said telematics control unit is programmed with at least one of a plurality of available vehicle operational modes, said plurality of vehicle modes comprising a vehicle rental mode and a vehicle sharing mode, wherein at least some vehicle operations permitted or prohibited by the telematics control unit while in vehicle rental mode differ from operations permitted or prohibited, respectively, while in vehicle sharing mode;

operating the telematics control unit to control vehicle access and systems, and to receive and communicate vehicle information and data to the fleet management system, in accordance with the mode programming.

13. The method of claim 12 further comprising the steps of:

providing a signal to change the vehicle operational mode to an alternative mode;

transmitting programming associated with such alternative mode from the management system to the telematics control unit; and

operating the telematics control unit to control vehicle access and systems devices in accordance with the alternative mode programming.

14. The method of claim 12, wherein each vehicle operational mode is associated with a different vehicle program, such that different fleet vehicles may be operated in different vehicle programs simultaneously.
