Abstract

An ignition control apparatus (10) for controlling ignition of a vehicle (270) equipped with a vehicle unit (1) comprising a display (3) and at least one port (5, 5′) adapted to receive a user data device (7, 7′), wherein the ignition control apparatus (10) is adapted to be connected to the vehicle unit (1) and to an ignition circuit (20) of the vehicle (270), wherein the ignition control apparatus (10) comprises means (11) for activating and deactivating the ignition circuit (20), depending on insertion of a user data device (7, 7′) into the port (5, 5′) and/or reception of an override signal (O). Further, a corresponding method, system and use thereof to control ignition of a vehicle (270) is disclosed.

First claim

The invention claimed is:

1. An ignition control apparatus, comprising:
a microprocessor arranged to read data signals from a vehicle unit installed in a vehicle in order to control activating and deactivating an ignition circuit of the vehicle,
wherein the ignition control apparatus is configured to be retrofitted into the vehicle to control ignition thereof,
wherein the vehicle unit is capable of recording, digitally collecting, and storing vehicle data and activities of a user during operation of the vehicle, the vehicle unit comprising a display and at least one card slot adapted to receive a user data device as a card including stored user data associated with the user,
wherein the ignition control apparatus is adapted to be connected between the vehicle unit and the ignition circuit of the vehicle,
wherein the ignition control apparatus is arranged to receive a data signal from the vehicle unit including information about activities being detected by the vehicle unit and indicating whether the user data device is inserted into the port card slot,
wherein the ignition control apparatus is arranged to activate the ignition circuit to allow ignition of the vehicle if the data signal indicates that the user data device is inserted into the card slot and to deactivate the ignition circuit to prevent ignition of the vehicle if the data signal indicates that the user data device is not inserted into the card slot, and
wherein if the data signal indicates that the user data device is not inserted into the card slot, the ignition control apparatus is further arranged to receive an override signal and to activate the ignition circuit to allow ignition of the vehicle in response to receiving the override signal.

2. The ignition control apparatus according to claim 1 , wherein the data signal is transmitted and received in serial communication over a vehicle bus network, including a Controller Area Network (CAN) bus or a Local Interconnect Network (LIN) bus, and/or a wireless network connection, including Bluetooth®, and wherein the data signal comprises serial data.

3. The ignition control apparatus according to claim 1 , wherein the activating and deactivating the ignition circuit comprises an electronic switch.

4. The ignition control apparatus according to claim 3 , wherein the electronic switch comprises one or more of a relay, a transmission gate, an analogue switch, and a MOSFET transistor.

5. The ignition control apparatus according to claim 1 , wherein the activating and deactivating the ignition circuit comprises generating and sending an activation signal to a control unit of the ignition circuit to allow ignition of the vehicle.

6. The ignition control apparatus according to claim 1 , wherein the override signal is in the data signal from the vehicle unit to the ignition control apparatus and comprises a sequence of activities initiated by the user and being detected by the vehicle unit.

7. The ignition control apparatus according to claim 1 ,
wherein the ignition control apparatus comprises circuitry to communicate with an external server comprising a database containing data relating to authorized user data devices, and
wherein the ignition control apparatus is arranged to verify whether the user data device inserted into the card slot of the vehicle unit is authorized and to activate the ignition circuit to allow ignition of the vehicle only if an authorized user data device is inserted into the card slot of the vehicle unit.

8. The ignition control apparatus according to claim 7 ,
wherein the data relating to authorized user data devices comprises an identifier and one or more of a time interval, route details, a list of locations, and type of vehicle associated with the user data device, and
wherein the verification of the user data device inserted into the card slot of the vehicle unit comprises comparing the data associated with the inserted user data device obtained from the external database and corresponding data obtained from the vehicle unit.

9. The ignition control apparatus according to claim 7 , wherein the override signal is received from the external server.

10. The ignition control apparatus according to claim 9 ,
wherein the override signal received from the external server defines a predetermined sequence of activities to be detected by the vehicle unit, and
wherein the ignition control apparatus is configured to verify that the sequence of activities detected by the vehicle unit corresponds to the predetermined sequence of activities to be detected by the vehicle unit defined by the override signal before activating the ignition circuit to allow ignition of the vehicle.

11. The ignition control apparatus according to claim 1 ,
wherein the ignition control apparatus is arranged to communicate with an external device, and
wherein the ignition control apparatus is arranged to activate the ignition circuit to allow ignition of the vehicle in response to receiving an override signal from the external device.

12. A method performed by an ignition control apparatus for controlling ignition of a vehicle equipped with a vehicle unit, the method comprising the steps:
receiving a data signal from the vehicle unit comprising information about the activities being detected by the vehicle unit and indicating whether the user data device is inserted into a card slot included in the vehicle unit and adapted to receive a user data device;
if the data signal indicates that the user data device is inserted into the card slot of the vehicle unit, activating an ignition circuit of the vehicle to allow ignition of the vehicle); or if the data signal indicates that the user data device is not inserted into the card slot of the vehicle unit, deactivating an ignition circuit of the vehicle to prevent ignition of the vehicle; and
if the data signal indicates that the user data device is not inserted into the card slot of the vehicle unit, in response to receiving an override signal, activating an ignition circuit of the vehicle to allow ignition of the vehicle, wherein
the vehicle unit is capable of recording, digitally collecting, and storing vehicle data and activities of a user during operation of the vehicle, the vehicle unit further including a display,
the ignition control apparatus is configured to be retrofitted into a vehicle,
the ignition control apparatus comprises a microprocessor arranged to read data signals from the vehicle unit installed in the vehicle in order to control activating and deactivating an ignition circuit of the vehicle, and
the ignition control apparatus is connected between the vehicle unit and the ignition circuit of the vehicle.

13. The method according to claim 12 , wherein the override signal is included in the data signal received from the vehicle unit and includes a predetermined sequence of activities initiated by the user and detected by the vehicle unit.

14. The method according to claim 12 , wherein the override signal is received from an external device or external server.

15. The method according to claim 14 , wherein the external server contains data relating to authorized user data devices, the method further comprising the steps:
communicating with the external server;
if the data signal indicates that the user data device is inserted into the card slot of the vehicle unit, verifying whether the inserted user data is authorized; and
activating the ignition circuit to allow ignition of the vehicle only if the inserted user data device is verified to be authorized.
