Definitions
- This application relates to improvements in so called smart card systems for detecting the presence of a card in a vehicle undergoing a change in status.
- remote controls which actuate door locks, ignition start, and other functions, remotely through an RKE device upon actuation of a switch.
- These devices known as keyfobs utilize a non-hard wire connection, such as an RF or LF connection.
- Vehicles incorporating the ability to communicate with such RKEs also typically have the ability to work with a mechanical key. These systems thus also require the use of some device which is actuated to request that a particular command be effected.
- the type of devices are known generically as "smart cards" and include a card carried by a user that authorizes the user to operate a particular vehicle.
- the card carries a coded signal which is checked by the vehicle computer to ensure that a proper operator for the vehicle is requesting the particular actuation.
- the card may have an LF transmitter/receiver, such as are commonly utilized in ignition lock systems.
- the operator When in a vehicle, the operator merely requests that the vehicle be started. No key is used.
- a sensor within the vehicle searches for an appropriate key in the vehicle. If the operator is carrying an appropriate key, then the sensor communicates with the vehicle control to actuate a signal to start the vehicle.
- the card may have the ability to receive a challenge coded signal from the vehicle, and modify that signal in a certain fashion. The modified signal is then transmitted back to the vehicle. The vehicle can determine whether the card is appropriate based upon the modification to the signal.
- the card and the vehicle are programmed together, in a fashion which is well within the skill of a worker in this art.
- the passenger may well be the passenger who is holding the appropriate card. That is, if a driver and passenger both enter a vehicle, the driver may not be holding the proper card, but rather the passenger is holding the card. The driver may have forgotten to bring the card. The vehicle would still start, however, since the passenger's card would be identified. If during the course of a trip the passenger leaves while the vehicle is still running ( i . e ., passenger dropped off at airport, etc.) the operator would be able to continue to operate the vehicle. However, if the operator stops after the passenger has left, and turns off the ignition, the operator would not be able to restart the vehicle.
- Another example of a problem with passive cards occurs if the passive card is left at a location in the vehicle, such as on the dash, in a console, etc. The driver may then leave the vehicle, and the vehicle doors could be locked. Since the driver is not carrying the card, the driver would not be able to enter the car.
- EP-A-0924370 describes a device for locking and unlocking a door of a motor vehicle which stores a drive authorisation code and warns if the device is removed from the vehicle.
- US-A-5293160 relates to a keyless vehicle lock system which provides a warning if a card is left in the vehicle or absent.
- the present invention is directed to providing warnings to an operator should situations such as outlined above occur with a smart card system.
- a method of operating a vehicle comprises the steps of
- a vehicle control system comprises a sensor for sensing presence of an appropriate card within a cab of a vehicle; a card provided with a code to be sensed by said sensor; at least one vehicle system to be operated upon a request from an operator, said sensor communicating with a control authorizing operation of said at least one system; characterised in that said system is a vehicle ignition; and in that the said control is operable upon receiving a request for a change in status of said at least one system to check for the presence of an authorized card within the cab of a vehicle receiving said system, said control providing a warning to an operator should a request for a change in status of the vehicle system not be advisable given that a request for stopping the ignition is received and no appropriate card is identified in the vehicle.
- a smart card system is provided with warnings to an operator when a card status in a vehicle may not be desirable given a requested action for the vehicle.
- a sensor prior to turning off the ignition on a vehicle a sensor will check the interior of the vehicle to ensure that there is a proper card still within the vehicle.
- the driver later asking for the ignition to be stopped would be provided with a warning that there is no valid card in the vehicle. If the driver has stopped at a spot on the way home, the driver would then have the opportunity to continue to drive the vehicle without turning off the ignition. A proper card could then be retrieved. In this way, the chance of a "walk home" situation for the driver would be avoided.
- a light and audio signal could be provided to the operator at the request of a ignition off if no proper card is sensed in the vehicle.
- the senor will check the interior of the vehicle to identify the presence of a card. If a card is sensed within the vehicle a warning signal is sent, such as an audio warning. This warning signal will allow the operator the opportunity to retrieve the card prior to the door locks being actuated.
- FIG 1A shows a vehicle 20 incorporating a smart card system.
- a sensor and control 22 is placed within the cab of the vehicle.
- a driver 24 and a passenger 26 are shown within the cab.
- the smart card 28 is held by the passenger 26.
- the driver 24 does not recognize that he did not bring his card with him.
- the control 22 will allow the vehicle to be started.
- the vehicle would have a start button 30 and a stop button 32.
- door lock controls 34 and 36 are also activated passively upon sensing of an appropriate card.
- the switches 30, 32, 34 and 36 are all simple actuation switches. No key is necessary to authorize the operation of these switches. This is one of the main benefits of effecting the smart key system. The several key lock mechanisms are no longer necessary.
- the passenger 26 has now exited the vehicle.
- the driver 24 has not stopped the vehicle, such as a situation where the passenger is being dropped off. If the driver then drives to another location, and attempts to stop the vehicle by actuating the stop button 32, the sensor 22 will first check to ensure the presence of a valid card within the vehicle. That is, prior to actuating the appropriate steps to stop the vehicle, the sensor 22 will first search the cab of the vehicle for a proper card. If no proper card is identified, then a signal 33 is sent to the operator. This signal can be both visual and audio. The operator will then have to re-actuate the stop ignition button 32 for the vehicle to be stopped.
- This system would thus provide the operator with the ability to not stop the vehicle in the event that the operator has forgotten his smart card.
- the present invention thus avoids the operator encountering a "walk home" situation.
- Figure 2 is a flowchart of the Figure 1 scenario. If an off request is received, the control will search the vehicle cab to identify the presence of a proper card. If a proper card is identified, then the ignition is stopped. If no proper card is identified, then a signal is sent. If a second request to stop is received, then the ignition is stopped.
- Figure 3 shows another scenario in which the control provides the operator with the ability of avoiding a potentially lock out undesirable situation.
- the operator 24 has left the vehicle but left the card 40 within the vehicle.
- the sensor 22 will scan the interior of the cab for an appropriate card. If an appropriate card 40 is sensed, then a signal is sent, such as by the visual warning 33, but also the audio warning 42 to identify the presence of the card 40 within the vehicle to the operator 24.
- the operator 24 will then be able to reopen the door 34, and retrieve the card 40.
- the door 34 will be locked with the operator 24 outside the vehicle and the card 40 inside the vehicle. In such a situation the operator would be unable to reopen the door.
- this system ensures that an operator will have the opportunity to retrieve a card prior to the door being locked.
- the control will initially search the cab for an appropriate card. If an appropriate card is found within the cab, then a warning will be actuated. If the operator then opens the door, the warning will be stopped.
- the system first checks to see whether the driver's door has been opened and closed within a predetermined period of time. This would provide an indication that the operator has left the vehicle. Once this has occurred, the control searches for the presence of a key within the vehicle. If no key is sensed, then the system returns to its steady state operation and the doors are locked. However, if a key is sensed, then a short period warning is sent. If the door is opened during this short warning period, then the system will again search for the presence of a key. If the key is no longer sensed, then the doors are locked. However, if a key is still sensed, then the warning will be sent again. The system can either continue to send the warning until either a second actuation of the door lock is manually received, or until a period of time has ended.
