Description

A theft deterrent system and method
Technical Field
The present disclosure relates a theft system and method for a vehicle and is particularly, although not exclusively, concerned with immobilising a stolen vehicle.
Background
Vehicles such as motorcycles are susceptible to theft. In order to deter thieves and to alert the owner that a theft is being attempted, alarm systems are sometimes installed in conventional motorcycles. These can include shock sensors that are triggered when the vehicle is moved or otherwise interfered with. However, even if the alarm is triggered it does not actively prevent the motorcycle being driven away. Immobilisers prevent the engine from running unless a correct key is inserted into the ignition.
However, these can be circumvented, and once the engine start, there is nothing to prevent a thief from driving away on the motorcycle.
There is a need for a means of preventing a person other than the driver from taking a motorcycle and driving away.

Steps in the predetermined sequence may be selectable by the user or may be predefined. The system may enable the user to select at least one step from a list of predetermined step and/or define alternative steps. The system may enable the user to modify characteristics of the steps such as the duration and/or order of each step. The controller may be configured to send a controlled pulse signal to the horn. The horn may sound 60 beeps per minute.
To avoid unnecessary duplication of effort and repetition of text in the specification, certain features are described in relation to only one or several aspects or embodiments of the invention. However, it is to be understood that, where it is technically possible, features described in relation to any aspect or embodiment of the invention may also be used with any other aspect or embodiment of the invention.
Brief Description of the Drawings
For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 is a schematic view of a theft deterrent system; and Figure 2 is a schematic view of a theft deterrent method.
Detailed Description
With reference to Figure 1, a theft deterrent system 2 comprises a vehicle controller 4 and a remote device 6.
The device 6 is configured to send a wireless signal to the controller 4 using a means of wireless communication such as Bluetooth®. The device 6 may be a personal device such as a smart phone which is usually kept on the body of the vehicle user.
The controller 4 comprises an antenna (not shown) configured to receive the wireless signal from the device 6. In some arrangements, the controller 4 may be configured to send a signal to the device 6.
The remote device may use any means of wireless communication, such as Bluetooth®. The controller 4 may be configured to receive signals from a plurality of devices and/or to receive signals from a plurality of means of wireless communication.
The controller 4 is configured to modify the performance of an engine of the vehicle upon the detection of a predetermined trigger event from the remote device 6. The trigger event may be any event such as a change in the signal being received by the controller 4, detecting the signal being below a predetermined level or a cessation of the signal being received by the controller 4. These trigger events may cause the controller 4 to modify the performance of the engine when the predetermined criteria has been met for a predetermined period of time. For example, a trigger event may be the controller 4 receiving no signal from the device 6 for a period of 10 seconds whilst the vehicle engine is running.
The controller 4 may be connected to an engine control unit. The controller 4 may send a signal to the engine control unit to modify the performance of the engine. On receipt of the signal, the engine control unit disables a feed to the engine such as a fuel supply or an electrical signal to an ignition system of the vehicle, for example. The engine control unit maybe be configured to resume the feed to the engine upon the signal ending.
In alternative arrangements, the engine control unit may be configured to disable a feed to the engine when it stops receiving a signal from the control unit. The engine control unit may be configured to resume a feed to the engine when the signal resumes. The system 2 may be configured to resume a feed to the engine when the user has enabled it to do so, by inputting a command to the device 6.
In some arrangements, the controller 4 may be configured to communicate with a fuel pump or fuel value, for example, in order to control the fuel supply to the engine.
The system 2 may be configured to monitor the condition of the vehicle wiring, such that if the wiring of the system 2 is damaged, the engine will not start.
In some arrangements, the controller 4 may be configured to modify the engine performance when the device 6 is outside Bluetooth® range.
In other arrangements, the controller 4 may be configured to calculate the speed profile of the vehicle and compare this to the rate of change of signal strength of the device 6.
If the user keeps the device 6 on their person, in the event that the user is pushed off the vehicle and an unauthorised person drives the vehicle away, the device 6 will remain with the user. The controller 4 may be configured to modify the engine performance, as the signal strength of the device reduces. Consequently, as the unauthorised person drives the vehicle away, the controller 4 will detect a decrease in the signal strength.
In such an event, the controller 4 will detect a decrease in the signal that corresponds with the vehicle moving away from the stationary device 6. The controller 4 may be configured to compare the rate of decrease in signal strength with the speed of the vehicle.
The trigger event may be the detection of a drop below a predetermined value of the strength of the signal, following a decline in the signal strength at a rate that substantially corresponds with the speed profile of the vehicle moving directly away from a position at which the decline began. This position corresponds to the device 6 remaining substantially stationary at the position where the decline in signal strength began. The controller 4 may be configured to modify the engine performance when the profile of the signal strength corresponds to the expected profile of a remote device 6 being dropped and the vehicle moving away.
The controller 4 may comprise a global positioning system 2 configured to monitor the speed profile and/or location of the vehicle, for example, in order to determine the trajectory of the vehicle in relation to the remote device 6. This relative trajectory may be monitored using the strength of the signal received by the controller 4 to determine the proximity of the remote device 6 from the vehicle.
The engine modification may comprise a sequence. The sequence comprises unaltered engine performance for a first period of time, beginning with the trigger event.
Then, the controller 4 provides an intermittent or continuous interruption of feed to the engine for a second period of time. The interruptions may occur at regular time intervals, or may occur at random or varying time intervals. The nature of the interruptions may be predetermined by the user. Then, the controller 4 stops the feed to the engine. The stopping of the feed to the engine may be accompanied by an alarm. The alarm may be communicated using the vehicle's horn. The horn may sound intermittently.
In some arrangements, the alarm may commence at a different position in the sequence.
If the controller 4 begins to receive a signal from the device 6 after the sequence has been initiated, the feed to the engine may resume. In some arrangements, the controller 4 may be configured to prevent the resumption of feed to the engine upon receiving the signal. The feed may resume upon request from the user.
The above described scenario and response may occur when the user has set the system 2 to be in a hijack mode. The user may also select different modes to be set at different times.
For example, in hijack mode, when the vehicle is out of Bluetooth range for 10 seconds, the controller 4 will interrupt the ignition at regular intervals over a period of 10 to 20 seconds, giving the driver a warning that there is an engine problem. After the predetermined period of ignition interruption, the ignition is switched off and the horn sounds intermittently.
In the event that a user parks the vehicle and moves away from the vehicle, with the device 6, the system 2 may enable the user to choose a parking mode. This mode may be automatically triggered when the ignition is off. Or, the user may positively select the parking mode on the device 6 or on the vehicle. In parking mode, the ignition is switched off and the user's wireless signal may be switched off, without triggering the controller 4 to modify engine performance. If the ignition is turned on whilst in parking mode, the controller 4 may be triggered to modify the engine performance (for example by disconnecting the ignition circuit). This deters unauthorised people from driving off on the vehicle when the vehicle is standing.
In some arrangements, the controller 4 may be turned off when the ignition is switched off.
If the signal from the device 6 ceases due to the device 6 losing power, being lost or breaking, the user can prevent the controller 4 from modifying the engine feed and/or triggering the alarm by performing a gesture. The gesture may be turning the ignition on and off a predetermined number of times. The number of times may be pre-selected upon installation and/or modified by the user.
The range of the wireless signal may vary according to the device 6 and/or the type of wireless communication. The controller 4 may be configured to initiate the modification of engine performance upon receiving a signal below a predetermined threshold signal level. The predetermined threshold may correspond with the device 6 being at or beyond a particular distance from the vehicle.
The controller 4 may be configured to communicate with at least one authorised device 6. In other arrangements, the controller 4 may be configured to communicate with a plurality of authorised devices. This may be advantageous in circumstances where more than one person uses the vehicle. The device 6 may require authorisation to perform commands such as modifying settings and/or resuming feed to the engine for example. The authorisation may require at least one level of passcode and/or biometric authentication, for example. In alternative arrangements, no authentication is required.
The system 2 may enable the user to select the nature of at least one trigger event and/or the engine modification resulting from the at least one trigger event. The system 2 may enable the user to select a plurality of trigger events and engine modifications. The user may select and change the settings on the device 6.
The controller 4 may be provided in a housing that can be mounted to any place on the vehicle such as in a rear panel. It is desirable to mount the housing in a position that is not easily accessible to a thief. The housing may be waterproof. The housing may comprise a waterproof box, for example. The dimensions of the box may be approximately 3cm by 2cm by 6cm, for example.
The system 2 may be battery powered. The user may select a mode of operation in which the feed to the engine is disabled when there is no power to the system. This has the advantage of reducing power consumption, since the system 2 can be turned off rather than put in standby mode which draws power.
With reference to Figure 2, a theft deterrent method 100 comprises step 102 of providing a vehicle controller 4 and step 104 of providing a remote device 6 configured to send a wireless signal to the controller 4. At step 106, the controller 4 modifies the performance of an engine upon the detection of a predetermined trigger event from the remote device 6.
The trigger event may be a change in the signal being received by the controller 4. For example, the controller 4 detecting the signal being below a predetermined level or a cessation of the signal being received by the controller 4 for a predetermined period of time.
The trigger event comprises the detection of the remote device 6 being out of Bluetooth® range for 10 seconds. The engine modification comprises the controller 4 interrupting the ignition at regular intervals over a period of 10 to 20 seconds, giving the driver a warning that there is an engine problem. After 10 to 20 seconds of the vehicle being out of Bluetooth® range, the ignition is cut and the horn sounds intermittently. The engine feed may resume when the device 6 is in Bluetooth® range of the controller 4 and/or upon the user enabling the engine using the device 6.
The time periods of method 100 and system 2 may be any suitable periods of time. The time periods may be set automatically or by the user. The time periods may be selected to minimise damage to the vehicle and/or the driver.
It will be appreciated by those skilled in the art that although the invention has been described by way of example, with reference to one or more exemplary examples, it is not limited to the disclosed examples and that alternative examples could be constructed without departing from the scope of the invention as defined by the appended claims.
