Technical Field

[0001] The present disclosure relates to a method for activating a vehicle alarm system for illuminating a target vehicle. The vehicle alarm system includes an alarm signal detection unit, wherein the alarm signal detection unit is configured to detect an alarm signal of the target vehicle. The present disclosure also relates to a vehicle alarm system for illuminating a target vehicle, and a vehicle including the vehicle alarm system for illuminating a target vehicle. Background Art

[0002] Alarm systems are very common in vehicle applications, and vehicles are equipped with intrusion alarms. The intrusion alarm emits an alarm signal when one or more sensors of the intrusion alarm are triggered by an intruder. The sensors of the intrusion alarm can be, for example, vibration sensors, door sensors, pressure sensors, motion detection sensors, tilt sensors, glass break sensors, or other suitable sensors used in the intrusion alarm system. When a sensor is triggered, the intrusion alarm system emits an alarm signal, which can be, for example, an acoustic signal, an optical signal, and / or a communication signal. Most intrusion alarms for vehicles use a flashing alarm signal and a horn alarm signal when triggered, but other communication signals can be used.

[0003] In a dark environment, such as at night, even if the alarm signal is triggered, the intruder can still move around without being seen.

[0004] Therefore, there is a need for an improved vehicle alarm system so that the intruder can be detected more easily. Summary of the Invention

This object is achieved at least in part by the features of the independent claims. The dependent claims contain further improvements to the method for activating a vehicle alarm system for illuminating a target vehicle and the vehicle alarm system for illuminating a target vehicle.

The vehicle alarm system includes an alarm signal detection unit, wherein the alarm signal detection unit is configured to detect an alarm signal of the target vehicle. The method includes the following steps: detecting, by the alarm signal detection unit, the alarm signal of the target vehicle when the anti-theft alarm of the target vehicle is activated; determining, when the alarm signal is detected, the angular direction of the vehicle relative to the target vehicle and the distance between the vehicle and the target vehicle; and activating, when the determined angular direction is within a predetermined angular direction range and the determined distance is within a predetermined distance range, a light source of the vehicle to illuminate the target vehicle and / or activating a light source of a device associated with the vehicle to illuminate the target vehicle.

[0007] The advantages of these features are that, under dark conditions, such as at night, it is more difficult for an intruder to operate without being seen, and thus the intruder is more easily detected.

The light determination unit can ensure in this way that the target vehicle is sufficiently illuminated by the light source. If the vehicle alarm system is arranged in multiple vehicles in the same area, the light determination unit can be used to control the number of light sources of different vehicles that need to be activated, or to determine whether the target vehicle is located under a street lamp.

[0029] Figure 2 Schematically shown in a top view is a vehicle including a vehicle alarm system for illuminating a target vehicle and the target vehicle.

[0030] Figure 3 Schematically shown in a top view are two vehicles including a vehicle alarm system for illuminating a target vehicle, and the target vehicle. DETAILED DESCRIPTION

[0031] Aspects of the present disclosure will be described below with reference to the accompanying drawings for purposes of illustration and not limitation, where like reference numerals denote like elements, and variations of the described aspects are not limited to the specifically shown embodiments but apply to other variations of the present disclosure.

[0032] Figure 1a-Figure 1c Schematically shown in different embodiments is a vehicle V parked in area A. Area A can be, for example, a defined parking area such as a parking lot, a parking garage, a street area, or other suitable areas for parking two or more vehicles.

[0033] Vehicle V includes a vehicle alarm system S AL , the vehicle alarm system S AL is configured to: when detecting an alarm signal S of an intrusion alarm 11 of a target vehicle V T , illuminate the target vehicle V T . Thus, the target vehicle V T is equipped with an intrusion alarm 11, where the target vehicle V TThe intrusion alarm 11 is configured to send out an alarm signal S when an intruder I triggers one or more sensors of the intrusion alarm 11. The sensors of the intrusion alarm 11 may be, for example, vibration sensors, door sensors, pressure sensors, motion detection sensors, tilt sensors, glass break sensors, or other suitable sensors used in vehicle intrusion alarm systems. When a sensor is triggered, the intrusion alarm 11 will send out an alarm signal S, which may be, for example, an acoustic signal, a visible signal, and / or a communication signal. Most vehicle intrusion alarms 11 use flashing light alarm signals and horn alarm signals when triggered, but other communication signals may also be used, such as transmitted V2V (vehicle-to-vehicle) intrusion alarm signals or V2X (Internet of Vehicles, Vehicle-to-Everything) intrusion alarm signals. Target vehicle V T A V2V intrusion alarm signal can be sent, and the vehicle alarm system S of vehicle V AL Directly detect. V2X intrusion alarm signal can be detected from the target vehicle V T The remote source can then transmit the signal to the area where the target vehicle is located for the vehicle alarm system S of the vehicle V. AL The remote source may be, for example, a service center, a node and / or a repeater. The V2V signal or the V2X signal may be transmitted in the form of a wireless communication signal, for example, via a mobile communication network, a Wi-Fi network or a Bluetooth network.

[0034] Vehicle Alarm System AL The alarm signal detection unit 21 is provided in the vehicle V and is configured to detect when the target vehicle V T The intrusion alarm 11 is triggered when the target vehicle V T In this way, the alarm signal detection unit 21 disposed in the vehicle V can detect the target vehicle V T The alarm signal detection unit 21 is equipped with a sensor or other detection device suitable for detecting the alarm signal S, such as a sensor or detection unit configured to detect an acoustic signal, a visual signal and / or a communication signal. Therefore, the sensor or detection unit of the alarm signal detection unit 21 can be used to detect a flashing light alarm signal, a horn alarm signal, a V2V alarm signal and / or a V2X alarm signal.

[0035] In an example embodiment, the warning signal S is a target vehicle V T When the intrusion alarm 11 is triggered, the alarm signal detection unit 21 is configured to detect the emitted sound signal. In this embodiment, the alarm signal detection unit 21 appropriately includes a microphone sensor to detect the target vehicle V T The sound signal emitted.

[0036] In an exemplary embodiment, the alarm signal S is an optical signal emitted by the target vehicle V T when the intrusion alarm 11 is triggered, and the alarm signal detection unit 21 is configured to detect the emitted optical signal. In this embodiment, the alarm signal detection unit 21 suitably includes a camera sensor to detect the optical signal emitted by the target vehicle V T emitted.

[0037] In an exemplary embodiment, the alarm signal S is a V2V communication signal emitted by the target vehicle V T when the intrusion alarm 11 is triggered, and the alarm signal detection unit 21 is configured to detect the emitted V2V communication signal. In this embodiment, the alarm signal detection unit 21 suitably includes a V2V signal sensor to detect the V2V communication signal emitted by the target vehicle V T emitted.

[0038] Vehicle alarm system S AL is configured to: when the alarm signal S is detected, determine the angular direction α of the vehicle V relative to the target vehicle V T and the distance D between the vehicle V and the target vehicle V T The angular direction α is suitably determined as the measured angular direction between the longitudinal direction D of the vehicle V LO and the position of the target vehicle V T as can be understood from, for example, Figure 1a-1b The distance D is suitably determined as the measured distance from the vehicle V to the target vehicle V T as indicated by the arrow in, for example, Figure 1a-1b .

[0039] Vehicle alarm system S AL further includes a distance and direction determination unit 23 provided in the vehicle V. The distance and direction determination unit 23 can be set as a suitable control unit and is configured to determine the angular direction α and the distance D to the target vehicle V T .

[0040] Depending on the configuration of the vehicle alarm system S AL and the distance and direction determination unit 23, the angular direction α of the vehicle V relative to the target vehicle V T can be measured and estimated between different parts of the vehicle V and the target vehicle V T . Therefore, the angular direction α can be expressed as an angular range. Depending on the configuration of the vehicle alarm system S AL and the distance and direction determination unit 23, the distance D between the vehicle V and the target vehicle V T can also be between different parts of the vehicle V and the target vehicle V TMeasured and estimated between different parts. Therefore, the distance D can be expressed as a distance range.

[0041] Vehicle alarm system S AL The distance and direction determination unit 23 can determine and calculate from the determined point P in the vehicle V D to the target vehicle V T the distance D and the angular direction α to the closest part of the vehicle V, as shown in the figure. The determined point P D can be, for example, any suitable point in the vehicle V where one or more sensors that form part of the distance and direction determination unit 23 and are used to determine the distance D and the angular direction α are located.

[0042] The distance and direction determination unit 23 can be set, for example, as a camera unit, a microphone unit, and / or a V2V unit within the vehicle V. The distance and direction determination unit 23 can use, for example, triangulation techniques and / or image detection and analysis techniques to determine the angular direction α and the distance D to the target vehicle V T The sensors used to determine the distance D and the angular direction α can be, for example, one or more of the following: a camera sensor, a microphone sensor, an ultrasonic sensor, a radar sensor, a lidar (LIDAR) sensor, a laser sensor, and / or a signal receiving sensor unit. The type of sensor used may depend on the alarm signal S emitted by the target vehicle V T , the configuration of the distance and direction determination unit 23, and the position of the target vehicle V T relative to the vehicle V.

[0043] When the alarm signal S is detected and it is determined that the measured angular direction α is within a predetermined angular direction range α PD and the measured distance D is within a predetermined distance range D PD , the light source 22 of the vehicle V will be activated to illuminate the target vehicle V T , and / or the light source 22 of the device X associated with the vehicle V will be activated to illuminate the target vehicle V T , as will be further described below. The vehicle V and / or the device X associated with the vehicle V has an illumination area A determined by the light source 22 L , and this illumination area A L is determined as the area that can be illuminated by the light source 22. The illumination area depends on the configuration of the light source 22 and may vary between different vehicles and devices according to the design, construction, and position of the light source 22. The light source 22 can use any suitable type of light to illuminate the target vehicle V T , such as visible light or near-infrared light.

[0044] Predetermined angular direction range α PD and the predetermined distance range D PD are related to the illumination area A Lis associated. Depending on the position of the target vehicle V T relative to the vehicle V, the illumination area A of the vehicle V L determines the possible range of the predetermined angular direction α PD and the predetermined distance range D PD . For example, Figure 1a the first point P1 in L is located within the illumination area A of the vehicle V and can thus be illuminated by the light source 22 of the vehicle V; Figure 1a the second point P2 in L is located outside the illumination area A of the vehicle V and cannot thus be illuminated by the light source 22 of the vehicle V.

[0045] The distance and direction determination unit 23 suitably includes one or more sensors located at the determined point P of the vehicle V as described above. Suitably, the predetermined angular direction range α D and the predetermined distance range D PD are set as distance and direction thresholds below which the vehicle V and / or the device X associated with the vehicle V can effectively illuminate the target vehicle V PD . T .

[0046] Depending on the configuration and design of the light source 22, the illumination area A L can be a three-dimensional light body with a complex three-dimensional geometry, and the predetermined distance range D PD can vary according to the angular direction α between the vehicle V or the device associated with the vehicle V and the target vehicle V T . Thus, for a specific light source 22 used in the vehicle V and / or the device X associated with the vehicle V, the predetermined angular direction range α AL and the predetermined distance range D PD of the vehicle alarm system S PD are suitably calibrated with each other. The vehicle alarm system S AL suitably determines, by this configuration, the distance D and the angular direction α from the determined point P in the vehicle V D to the closest part of the target vehicle V T . When the distance and direction determination unit 23 provided in the vehicle V determines the angular direction α relative to the target vehicle V T and the distance D to the target vehicle V T , and when the determined angular direction α is within the predetermined angular direction range α PD and the determined distance D is within the predetermined distance range D PD , the vehicle V and / or the device X associated with the vehicle V activates the light source 22 to illuminate the target vehicle V T .

[0047] Therefore, the vehicle alarm system S ALWhen the alarm signal S is detected, the light source 22 is activated only if the determined angular direction α lies within a predetermined angular direction range α PD and the determined distance D lies within a predetermined distance range D PD . If the determined angular direction α exceeds the predetermined angular direction range α PD , even if the alarm signal S emitted by the target vehicle V T is detected, the light source 22 will not be activated. If the determined distance D is outside the predetermined distance range D PD , even if the alarm signal S emitted by the target vehicle V T is detected, the light source 22 will not be activated.

[0048] In Figure 1a , an exemplary operating scenario of the vehicle alarm system S AL is schematically shown. As shown, the vehicle V and the target vehicle V T are parked in area A, and the target vehicle V T is parked directly in front of the vehicle V.

[0049] In Figure 1a the exemplary embodiment shown, the distance and direction determination unit 23 of the vehicle alarm system S AL is correctly determining the distance D and the angular direction α from a determination point located at the center of the front end of the vehicle V PD to the closest part of the target vehicle V T to the vehicle V, as shown. In the embodiment shown, when the alarm signal S emitted by the target vehicle V T is detected, the distance D and the angular direction α are in a direction parallel to the longitudinal direction D LO of the vehicle V, from the center of the front end of the vehicle V to the rear end of the target vehicle V T . As described above, the target vehicle V T is parked directly in front of the vehicle V, and at the position shown in Figure 1a , the longitudinal direction D LO of the vehicle V and the target vehicle V T The angular direction α between the positions is zero degrees. Therefore, the angular direction α coincides with the longitudinal direction D LO of the vehicle V.

[0050] The vehicle V includes a light source 22, and in Figure 1a the embodiment shown, the light source 22 is provided as two front headlights of the vehicle V. The vehicle V has an illumination area A L determined by the light source 22, and as described above, this illumination area A L is determined as the area that can be illuminated by the light source 22. The illumination area depends on the configuration of the light source 22 and may vary between different vehicles according to the design, construction, and position of the light source 22.

[0051] As Figure 1a shown, when an intruder I triggers one or more sensors of the intrusion alarm 11 of the target vehicle V T , the intrusion alarm 11 of the target vehicle V T is activated and emits an alarm signal S. When the alarm signal detection unit 21 of the vehicle V detects the alarm signal S emitted when the intrusion alarm 11 of the target vehicle V T is activated, the distance and direction determination unit 23 provided in the vehicle V will determine the angular direction α of the vehicle V relative to the target vehicle V T , and the distance D between the vehicle V and the target vehicle V T . When it is determined that the angular direction α is within a predetermined angular direction range α T and the distance D is within a predetermined distance range D PD , the vehicle V will activate the light source 22 to illuminate the target vehicle V PD . In this way, when the alarm signal detection unit 21 of the vehicle V detects the alarm signal S of the target vehicle V T , the target vehicle V T will be effectively illuminated by the vehicle V, so the light source 22 can be used to deter the intruder I who triggers the intrusion alarm 11 of the target vehicle V T . T

[0052] The predetermined angular direction range α PD and the predetermined distance range D PD are associated with the illumination area A L . According to the position of the target vehicle V T relative to the vehicle V, the illumination area A of the vehicle V L determines the possible predetermined angular direction range α PD and the predetermined distance range D PD . As Figure 1a shown, the target vehicle V T is located within the illumination area A of the vehicle V L , and thus can be illuminated by the light source 22 of the vehicle V

[0053] The distance and direction determination unit 23 includes one or more sensors located at the determination point P of the vehicle V D . In Figure 1a the illustrated embodiment, the predetermined angular direction range α PD and the predetermined distance range D PD are set as distance and direction thresholds at which the vehicle V can effectively illuminate the target vehicle V T . Depending on the configuration and design of the light source, the illumination area 22 can be a three-dimensional light body with a complex three-dimensional geometry, and the predetermined distance range D PD ​It can vary according to the angular direction α between the vehicle V and the target vehicle V T For the light source 22 used in the vehicle V, the vehicle alarm system S AL predetermined angular direction range α PD and the predetermined distance range D PD are calibrated with each other. The vehicle alarm system S AL determines the distance D and the angular direction α from the determined point P in the vehicle V D to the closest part of the target vehicle V T as shown by the arrow in Figure 1a . In the embodiment shown in Figure 1a , the target vehicle V T is located within the possible range of the predetermined angular direction α PD and the predetermined distance D PD , and the vehicle V can effectively illuminate the target vehicle V T . Therefore, when the distance and direction determination unit 23 arranged in the vehicle V determines the angular direction α relative to the target vehicle V T and the distance D to the target vehicle V T , and when the determined angular direction α is within the predetermined angular direction range α PD and the determined distance D is within the predetermined distance range D PD , the vehicle V activates the light source 22 to effectively illuminate the target vehicle V T .

[0054] In Figure 1a the shown embodiment, the vehicle alarm system S AL activates the light source 22 only when the following conditions are met upon detecting the alarm signal S: the determined angular direction α is within the predetermined angular direction range α PD and the determined distance D is within the predetermined distance range D PD . If the determined angular direction α exceeds the predetermined angular direction range α PD , then the light source 22 is not activated upon detecting the alarm signal S from the target vehicle V T . If the determined distance D exceeds the predetermined distance range D PD , then the light source 22 is not activated upon detecting the alarm signal S from the target vehicle V T .

[0055] In Figure 1b , another exemplary operation scenario of the vehicle alarm system S AL is schematically shown. The vehicle V and the target vehicle V T are parked in area A. In this embodiment, the target vehicle V T is parked in front of and to the right of the vehicle V. The target vehicle V TThe parked angular direction α and the longitudinal direction D of the vehicle V LO are not parallel, so the angular direction α and the longitudinal direction D of the vehicle V LO are different.

[0056] In Figure 1b the illustrated exemplary embodiment, as shown in the figure, the distance and direction determination unit 23 of the vehicle alarm system S AL is correctly determining the distance D and the angular direction α from the determination point PD located at the middle of the front end of the vehicle V to the closest part of the target vehicle V T on the vehicle V. In Figure 1b the illustrated position, when the alarm signal S emitted from the target vehicle V T is detected, the distance D and the angular direction α are measured from the middle of the front end of the vehicle V to the left rear corner of the target vehicle V T as shown.

[0057] The vehicle V includes a light source 22, and in Figure 1b the illustrated embodiment, the light source 22 is provided as the two front headlights of the vehicle V. The vehicle V has an illuminated area A L determined by the light source 22, and as described above, the illuminated area A L is determined as the area that can be illuminated by the light source 22.

[0058] Figure 1b The light source 22 of the illustrated vehicle has an illuminated area A L . According to the position of the target vehicle V T relative to the vehicle V, the illuminated area A of the vehicle V L determines a possible predetermined angular direction range α PD and a predetermined distance range D PD . The predetermined angular direction range α PD and the predetermined distance range D PD are associated with the illuminated area A L . It can be understood from Figure 1b that the target vehicle V T is arranged outside the illuminated area A of the vehicle V L , and the target vehicle V T cannot be illuminated by the light source 22 of the vehicle V.

[0059] When the intruder I triggers one or more sensors of the intrusion alarm 11 of the target vehicle V T as shown in Figure 1b , the intrusion alarm 11 of the target vehicle V T is activated and emits an alarm signal S. When the alarm signal S emitted after the activation of the intrusion alarm 11 of the target vehicle V T is detected by the alarm signal detection unit 21 of the vehicle V, the vehicle V relative to the target vehicle VT the angular direction α and the distance D between the vehicle V and the target vehicle V T are determined by a distance and direction determination unit 23 arranged in the vehicle V. In Figure 1b the illustrated embodiment, the determined angular direction α exceeds a predetermined angular direction range α PD , and thus the distance D also exceeds a predetermined distance range D PD . Accordingly, the vehicle V does not activate the light source 22 to illuminate the target vehicle V T .

[0060] The distance and direction determination unit 23 includes one or more sensors located at a determination point P of the vehicle V D . In Figure 1b the illustrated embodiment, the predetermined angular direction range α PD and the predetermined distance range D PD are set as distance and direction thresholds at which the vehicle V can effectively illuminate the target vehicle V T . Depending on the configuration and design of the light source, the illumination area 22 can be a three-dimensional light body with a complex three-dimensional geometry, and the predetermined distance range D PD may vary according to the angular direction α between the vehicle V and the target vehicle V T . For the light source 22 used in the vehicle V, the predetermined angular direction range α AL and the predetermined distance range D PD of the vehicle alarm system S PD are calibrated with each other. The vehicle alarm system S AL determines the distance D and the angular direction α from the determination point P in the vehicle V D to the closest part of the target vehicle V T , as indicated by the arrow in Figure 1b .

L , and the illuminated area A of device X L The area determined to be illuminable by the light source 22 of the device X. It should be understood that the illuminated area A of the device X L Determined by the operating range of device X relative to the vehicle V with which it is associated.

[0066] When the intruder I triggers the target vehicle V T When one or more sensors of the intrusion alarm 11 are Figure 1c As shown, the target vehicle V T The anti-theft alarm 11 is activated and sends out an alarm signal S. When the target vehicle V T After the anti-theft alarm 11 is activated, the target vehicle V T When the alarm signal S sent is detected by the alarm signal detection unit 21 of the vehicle V, the vehicle V moves relative to the target vehicle V T The angle direction α and the angle between the vehicle V and the target vehicle V T The distance D therebetween is determined by a distance and direction determination unit 23 arranged in the vehicle V.

[0067] exist Figure 1c In the embodiment shown, the target vehicle V T In conjunction with the above Figure 1b The same method is located in the illuminated area A of the vehicle V L Therefore, when the target vehicle V is detected T When the warning signal S is received, the vehicle V will not activate the light source 22 to illuminate the target vehicle V T .

[0068] However, in Figure 1c In the embodiment shown, the target vehicle V T Located in the illuminated area A of device X L Therefore, when the target vehicle V is detected T When the alarm signal S is received, the device X can activate its light source 22 to illuminate the target vehicle V T .

[0069] The distance and direction determination unit 23 includes a determination point P located at the vehicle V D One or more sensors at Figure 1c In the embodiment shown, the predetermined angular direction range α PD and the predetermined distance range D PD The device X is set to effectively illuminate the target vehicle V within the vehicle V and its operating range.T Distance and direction thresholds. Depending on the configuration and design of the light source, the illuminated area 22 can be a three-dimensional light body with a complex three-dimensional geometry, and the predetermined distance range D PD may vary according to the angular direction α between the vehicle V and the target vehicle V T and the operating range of the device X. For the light source 22 used in the vehicle V and the light source used in the device X, the vehicle alarm system S AL predetermined angular direction range α PD and the predetermined distance range D PD are calibrated with each other. The vehicle alarm system S AL determines the distance D and the angular direction α from the determined point P in the vehicle V D to the closest part of the target vehicle V T as shown by the arrow in Figure 1c . As shown in Figure 1b , the target vehicle V T is located outside the possible range of the illuminated area A of the vehicle V L , and the target vehicle V T cannot be illuminated by the vehicle V. Therefore, the vehicle V does not activate the light source 22. However, as shown in Figure 1c , the target vehicle V T is located within the possible range of the illuminated area A of the device X L , and the target vehicle V T can be illuminated by the device X. Therefore, the device X can activate the light source 22.

[0070] Figure 1c In the embodiment shown in AL , the vehicle alarm system S PD will activate the light source 22 of the vehicle V and / or the light source 22 of the device X only when the following conditions are met: the determined angular direction α is within the predetermined angular direction range α PD , and the determined distance D is within the predetermined distance range D T . It should be understood that when the target vehicle V L is located within the possible illuminated areas A of both the vehicle V and the device X AL , the vehicle alarm system S T can activate the light sources 22 of both the vehicle V and the device X simultaneously. When the target vehicle V L is located outside the possible illuminated areas A of both the vehicle V and the device X AL , the vehicle alarm system S

In this embodiment, the target vehicle V T Is parked in front of vehicle V and to the left. The target vehicle V T The parking angle direction α is not parallel to the longitudinal direction D of vehicle V LO So this angle direction α is not parallel to the longitudinal direction D of vehicle V LO Is different. In this embodiment, vehicle V is equipped with a light source 22 arranged movably, which can be directed to different positions. Appropriately, the light source 22 is set as an active or adaptive headlight. Such headlights can be configured to adapt to changing road conditions (such as curves) to better illuminate the road on the driving path. The active or adaptive headlights can also be connected to the vehicle alarm system SAL and used to change the direction of the light source 22. In this way, compared with traditional immovably arranged headlights, the illuminated area A L Can be significantly larger, or the light source 22 can be aligned with the target vehicle V T To obtain a higher light intensity. In addition to the movably arranged light source 22, the arrangement and structure of the alarm system S AL Can be as described in the above embodiment. Through this configuration of the light source 22, the vehicle alarm system S AL Actively aligns the light source 22 of vehicle V with the target vehicle V when receiving the alarm signal S T To illuminate the target vehicle V T . In this exemplary operation scenario where the movably arranged light source 22 of vehicle V illuminates the target vehicle V T , it is assumed that the determined angle direction α is within a predetermined angle direction range α PD And the determined distance D is within a predetermined distance range D PD .

When receiving the alarm signal S, the light source 22 of the device X can actively align with the target vehicle V T To illuminate the target vehicle V T . The light source 22 of the device X can be arranged movably, or the device X itself can change its position to actively change the direction of the light source (actively directing the light source). In this exemplary operation scenario where the light source 22 of the device X illuminates the target vehicle V T , it is assumed that the determined angle direction α is within a predetermined angle direction range α PD And the determined distance D is within a predetermined distance range D PD .

In addition to the movably arranged light source 22, for each of the two vehicles, the arrangement and construction of the alarm system S AL can be as described in the embodiment above in connection with Figure 1a-1c . With such a configuration of the light sources 22 of the first vehicle V1 and the second vehicle V2, the vehicle alarm system S AL can actively direct the light source 22 of any of the two vehicles V towards the target vehicle V T when receiving the alarm signal S to illuminate the target vehicle V T . In order for the light source 22 of the first vehicle V1 to illuminate the target vehicle V T , the determined angular direction α of the first vehicle V1 relative to the target vehicle V T needs to be within a predetermined angular direction range α PD , and the determined distance between the first vehicle V1 and the target vehicle V TThe distance D therebetween needs to be within a predetermined distance range D PD so that the light source 22 of the second vehicle V2 illuminates the target vehicle V T , the determined angular direction α of the second vehicle V2 relative to the target vehicle V T needs to be within a predetermined angular direction range α PD , and the determined distance D between the second vehicle V2 and the target vehicle V T needs to be within a predetermined distance range D PD In a specific embodiment, the target vehicle may activate V2V communication to request the positions and directions of nearby vehicles, such as the first vehicle V1 and the second vehicle V2. If it is determined that the first vehicle V1 and the second vehicle V2 are very close to the target vehicle V T , V2V communication may be used between the first vehicle V1 and the second vehicle V2 to determine whether one or both vehicles illuminate the target vehicle V T .

[0075] For different embodiments, the vehicle alarm system S AL may further include a light determination unit 24 disposed in the vehicle V.

After the vehicle V activates the light source 22, the light determination unit 24 can use the frame-by-frame comparison technique to compare whether the light source 22 significantly changes the illuminated state of the target vehicle V T . If multiple vehicles V in the same area A are all provided with the vehicle alarm system S AL , the light determination unit 24 can be used to control the number of light sources of different vehicles V that need to be activated, or to determine whether the target vehicle V T is located under a street lamp.
