Abstract

A start system for a vehicle, the system comprising scanning means arranged so as to scan an area around a driver'"'"'s seat of the vehicle to detect an authorization device having a particular level of authorization so as to ensure that only a person carrying an authorization device having this level of authorization and positioned in the area around the driver'"'"'s seat may start the vehicle wherein the system further comprises input means and the input means comprises a pair of switches both of which must be actuated for the vehicle to start.

Claims

1. A start system for a vehicle, the system comprising scanning means arranged so as to scan an area around a driver'"'"'s seat of the vehicle to detect an authorisation device having a particular level of authorisation so as to ensure that only a person carrying an authorisation device having this level of authorisation and positioned in the area around the driver'"'"'s seat may start the vehicle wherein the system further comprises input means and the input means comprises a pair of switches both of which must be actuated for the vehicle to start.

2. A start and entry system for a vehicle, the system comprising first scanning means to scan an area around the vehicle for the existence of one or more authorisation devices having a first level of authorisation so as to enable entry to the vehicle, and second scanning means arranged so as to scan an area around a driver'"'"'s seat of the vehicle to detect an authorisation device having a second level of authorisation so as to ensure that only a person carrying an authorisation device having this level of authorisation and positioned in the area around the driver'"'"'s seat may start the vehicle.

3. A system according to claim 2 further comprising input means located proximate the driver'"'"'s seat wherein only once the input means is closed does the vehicle start.

4. A system according to claim 3 wherein the input means comprises a pair of switches both of which must be actuated for the vehicle to start.

5. A system according to claim 4 wherein the switches are sufficiently mutually remote so as not to be capable of engagement by a single hand.

6. A system according to claim 5 wherein the input means is located on a steering wheel provided in the vehicle.

7. A system according to claim 2 wherein the or each authorisation device is a transponder.

8. A system according to claim 2 wherein the first and/or second scanning means scan using electromagnetic radiation.

9. A system according to claim 2 wherein the or each authorisation device has an identity code.

10. A system according to claim 2 wherein the first and/or second scanning means obtain the identity code and compare the code with identity codes stored in a corresponding first and second memory to determine whether a particular authorisation device has either the first or second level of authorisation.

11. A system according to claim 2 further having means arranged to stop the vehicle and/or selectively lock one or more vehicle doors.

12. A system according to claim 11 wherein the locking means locks the vehicle door(s) once the authorisation device moves out of range of the first scanning means.

13. A system according to claim 11 wherein the stop means stops the vehicle once the authorisation device moves out of range of the second scanning means.

15. A system according to claim 14 wherein the switches are mounted on a steering wheel of the vehicle.

16. A system according to claim 14 wherein the switches are actuated, in use, by the vehicle user grasping the steering wheel.

17. A system according to claim 14 wherein the switches comprise touch sensors.

18. A system according to claim 14 wherein at least one of the switches is monostable.

14. A start system for a vehicle comprising first and second switches, wherein both switches must be actuated in any order to enable the vehicle to start and wherein the switches are sufficiently mutually spaced to prevent actuation thereof by a single hand of a vehicle user.

19. A vehicle start method comprising the steps of:

(i) a scanning means detecting an authorisation device associated with a user only when a user is sitting in a driver'"'"'s seat of the vehicle; and

(ii) the scanning means authenticating the authorisation device for a particular level of authorisation to permit vehicle starting; and

(iii) the user closing a pair of switches to start the vehicle.

20. A vehicle entry and start method comprising the steps of:

(i) a first scanning means detecting an authorisation associated with a user when located outside the vehicle device;

(ii) the first scanning means authenticating the authorisation device for a first level of authorisation to permit vehicle entry;

(iii) a second scanning means detecting the authorisation device only when the user is sitting in a driver'"'"'s seat of the vehicle; and

(iv) the second scanning means authenticating the authorisation device for a second level of authorisation to permit vehicle starting.
