Abstract

An apparatus 5 for stopping a vehicle 2 having an internal combustion engine 3, has a projectile launcher 8 for launching a projectile 9 towards an open end 16 of an exhaust pipe 4 of the vehicle 2. The projectile 9 to be launched has a material that is arranged to expand when exposed to heat from the exhaust pipe 4, the material arranged to obstruct exhaust expelled from the exhaust pipe 4 so as to cause the vehicle 2 to stop when the projectile 9 is at least partially within the exhaust pipe 4. The apparatus may also include an aiming device that detects heat from the open end 16 of the exhaust 4, or may use a reflected laser beam light system to guide the projectile. The apparatus may be attached to a pursuit vehicle and may be used by the Police to stop a fleeing vehicle without injury or damage.

Description

APPARATUS FOR STOPPING A VEHICLE HAVING
AN INTERNAL COMBUSTION ENGINE
The present invention relates to an apparatus for stopping a vehicle having an internal combustion engine.
A fleeing vehicle may need to be stopped by the Police. One way of stopping the vehicle is to lay a series of spikes in the road in front of the vehicle wherein the tyres of the vehicle are burst by the spikes. However, there is a problem in that a vehicle with burst tyres is likely to continue for some distance past the spikes and be out of control so that it could cause injury or damage.
It is an object of the present invention to provide an apparatus to alleviate the above-mentioned problem.
According to the present invention there is provided an apparatus for stopping a vehicle having an internal combustion engine, comprising: a projectile, and a projectile launcher for launching the projectile towards an open end of an exhaust pipe of the vehicle, the projectile comprising a material that is arranged to expand when exposed to heat from the exhaust pipe, the material arranged to obstruct exhaust expelled from the exhaust pipe so as to cause the vehicle to stop when the projectile is at least partially within the exhaust pipe.
This causes the vehicle to be brought slowly to a halt in a more controlled manner.
The apparatus may include an aiming device for aiming the projectile to be launched at the open end of the exhaust pipe. The aiming device may be arranged to aim the projectile launcher at the open end of the exhaust pipe.
The aiming device may be arranged to detect heat or infrared radiation from the open end of the exhaust pipe in order to aim the projectile launcher.
The projectile may have a heat or infrared radiation seeking guidance device for guiding the projectile to the end of the exhaust pipe.
The apparatus may include a laser designator for marking the open end of the exhaust pipe. The aiming device may be arranged to detect reflected laser light from the marked exhaust pipe in order to aim the projectile launcher.
The projectile may have a reflected laser light seeking guidance device for guiding the projectile to the marked exhaust pipe.
The projectile launcher may be arranged to hold a plurality of the projectiles for launching. The projectile launcher may have propulsion means for propelling the projectile out of the projectile launcher. The projectile may have propulsion means for propelling the projectile out of the projectile launcher.
A pursuit vehicle may be provided which includes the apparatus as described above. By the pursuit vehicle including this apparatus, there is no need to guess where spikes should be laid to stop a pursued vehicle, as the pursuit vehicle would be following the pursued vehicle.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying schematic drawings, in which: Figure 1 is an elevational view of a pursuit vehicle and a pursued vehicle, the pursuit vehicle including an apparatus for stopping the pursued vehicle according to one embodiment of the invention; Figure 2 is a block diagram of the apparatus; Figure 3 is view of a projectile to be launched by a projectile launcher of the apparatus; Figure 4 is a perspective view of the projectile launcher; and Figure 5 is an elevational view of a portion of the pursuit vehicle and the pursued vehicle, the pursuit vehicle including an apparatus for stopping the pursued vehicle according to another embodiment of the invention.
Referring to Figure 1 of the accompanying drawings, a pursuit vehicle 1 and a pursued vehicle 2 are shown. The pursued vehicle 2 has an internal combustion engine 3 and an exhaust pipe 4 connected to the engine.
Referring additionally to Figure 2, the pursuit vehicle 1 has an apparatus for stopping the pursued vehicle 2. The apparatus 5 comprises a control unit 6 to which are connected a display screen 7, a projectile launcher 8 holding a plurality of projectiles 9 (see also Figure 4), and an actuator 10 for the projectile launcher 8. The projectile launcher 8 has a motorized mounting 11 for changing the elevation and direction of the projectiles 9 held in the projectile launcher 8.
The projectile launcher 8 also has an infrared sensor 12 and a digital camera 13 which are connected to the control unit 6. The display screen 7 and the actuator 10 are located inside the pursuit vehicle 1.
Referring to Figure 3, each projectile 9 has flight stabilising fins 14. The projectile 9 also comprises a material 15 that is arranged to expand when exposed to heat.
In use, when the pursuit vehicle 1 is chasing a pursued or fleeing vehicle 2 that is to be stopped, the infrared sensor 12 detects heat from the exhaust pipe 4 of the pursued vehicle 2, and causes the projectile launcher 8 to adjust its position so that the projectile 9 to be launched is aimed at the open end 16 of the exhaust pipe 4 of the pursued vehicle 2. The display screen 7 shows that the projectile 9 is aimed at the exhaust pipe 4, and a person inside the pursuit vehicle 1 viewing the display screen 7 can actuate the actuator 10 to fire the projectile 9 at the open end 16 of the exhaust pipe 4.
When the projectile 9 enters the exhaust pipe 4 via its open end 16, the material 15 in the projectile 9 expands as it is exposed to heat from the exhaust pipe 4. The expanded material 9 thus obstructs exhaust expelled from the exhaust pipe 4 so as to cause the pursed vehicle 2 to stop.
The projectile launcher 8 may propel the projectile 9, for example, by means of an explosive charge or a gas canister or by releasing a compressed expansion spring.
Alternatively, the projectile is a rocket that propels itself out of the projectile launcher. The projectile may have an infrared sensor package on the tip of the projectile and adjustable flight control fins so that a launched projectile can guide itself to the end of the exhaust pipe. The projectile launcher consequently does not require the infrared sensor, and can be approximated positioned in the right direction by, say, a joystick controlled by a person in the pursuit vehicle.
The expandable material 15 of the projectile 9 may comprise a foam or plastic that expands on being exposed to heat from the exhaust pipe 4.
If the pursued vehicle 2 has more than one exhaust pipe then a separate projectile 9 is required to block each exhaust pipe.
Referring to Figure 5, the pursuit vehicle 20 has an apparatus 21 according to another embodiment of the invention wherein the apparatus 21 has a laser designator 22, and the projectile launcher 23 has a laser seeker head 24 instead of an infrared sensor. The laser designator 22 marks the exhaust pipe 4 of the pursued vehicle 2, and reflected laser light from the exhaust pipe 4 is then detected by the seeker head 24 causing the projectile launcher 23 to adjust its position so that the projectile 25 to be launched is aimed at the open end 16 of the exhaust pipe 4 of the pursued vehicle 2. For this embodiment, the laser may be replaced by any other suitable type of beam.
In a modification, the projectile may be a rocket that has a reflected laser light seeker head and adjustable flight control fins. The projectile launcher consequently does not require the laser seeker head as the launched projectile can guide itself to the end of the exhaust pipe.
Whilst particular embodiments have been described, it will be understood that various modifications may be made without departing from the scope of the invention. Although the apparatus is described as being used to stop a vehicle which is illustrated as being a car, the apparatus could be used to stop other vehicles, including boats, providing that they have an internal combustion engine and an exhaust.
