The automatic driving vehicle depends on the cooperation of artificial intelligence, visual calculation, monitoring device, global positioning system, etc. to make the computer operate the motor vehicle automatically and safely without any human active operation.
The inventors of the present application propose: when an external dangerous event occurs at a parking lot, for example, a user is generally unable to drive a vehicle away from the dangerous spot because the user is not on the spot, thereby causing economic loss; in particular, combustion or explosion of one vehicle may affect a vehicle parked in the surroundings to cause a serious chain reaction in case of fire, for example; thus, when an external hazard event (e.g., a fire or flood) is encountered, further economic and/or personal injury can be avoided if the autonomous vehicle is able to operate autonomously accordingly from the external hazard event.
Disclosure of Invention
The object of the present invention is to provide a safety system for a vehicle and a vehicle having such a safety system, which enables the vehicle to be operated in an improved manner when an external hazard event is encountered, so that the vehicle can be protected from the external hazard event or is influenced as little as possible by the external hazard event.
The above task is achieved by a safety system for a vehicle according to the present invention, the vehicle being an autonomous vehicle, the safety system comprising: a sensor unit for detecting a surrounding environment of the vehicle; an analysis processing unit for determining whether an external hazard event occurs according to the information received by the sensor unit and evaluating a location and an action range of the external hazard event; and the control unit is used for activating the automatic driving function of the vehicle and controlling the vehicle to automatically drive to a safe position outside the action range of the external dangerous event when the analysis processing unit determines that the external dangerous event occurs.
The inventors of the present application propose: in life, people often encounter the situation that in an underground parking lot or in a remote area, a network signal is poor and communication with the internet cannot be obtained, or in the case of fire or flood, communication equipment in the parking lot is damaged and communication with the internet cannot be obtained in time. Even in this case, the invention makes it possible to protect the vehicle from damage from dangerous events in a particularly advantageous manner.
In particular, the surroundings of the vehicle are detected by means of the safety system according to the invention, and in the event of a hazard event the specific location, the range of action, or even the development thereof, of the hazard event is evaluated and analyzed, while the vehicle is automatically driven into a safety position outside the range and/or the spread of the development of the hazard event on the basis of the electronic map of the on-board navigation system itself.
The concept of an autonomous vehicle according to the invention is to be understood to mean that the vehicle is capable of automated longitudinal guidance and lateral guidance or of autonomous driving with automated longitudinal guidance and lateral guidance. In the driving without a driver, the vehicle can automatically finish the driving under all conditions in the whole driving period, and can also automatically find a proper parking space or a charging pile. At present, the automatic driving technology is rapidly developed. The automatic driving vehicle depends on the cooperation of artificial intelligence, visual calculation, monitoring device, global positioning system, etc. to make the computer operate the motor vehicle automatically and safely without any human active operation.
In one embodiment, the external hazard event comprises an external thermal event, a flood event, and/or a seismic event. In one embodiment, the sensor unit includes: smoke sensors, gas sensors, temperature sensors, infrared sensors, image sensors and/or sound sensors.
In one embodiment, the control unit sends an alarm message to the owner of the vehicle in case the analysis processing unit determines that an external dangerous event has occurred. The control unit controls the vehicle to automatically travel to a safe position confirmed by the owner of the vehicle. Alternatively, the control unit selects a safe position outside the scope of action of the external hazard event according to a predetermined strategy and controls the vehicle to automatically drive to the safe position without confirmation by the owner of the vehicle.
In one embodiment, the control unit sends an alarm message to a fire department in case the analysis processing unit determines that an external dangerous event occurs. Alternatively or additionally, the control unit controls the vehicle to sound a hazard alarm and/or a hazard lamp in case the analysis processing unit determines that an external hazard event occurs.
In one embodiment, the control unit sends the information of the safety position to the owner of the vehicle after controlling the vehicle to automatically drive to the safety position.
In one embodiment, the security system is connectable to a vehicle power source and to a separate power source device.
In one embodiment, the vehicle is an electric vehicle, and the control unit is capable of interrupting the charging process and controlling the vehicle to automatically travel to a safe position according to a current state of charge (SOC) in case the analysis processing unit determines that an external dangerous event occurs during the parking charging. Alternatively, in the event of a shortage of charge, the control unit can switch the charging process to a rapid charging mode, and interrupt the charging process and control the vehicle to automatically drive to a safe position after the state of charge is sufficient to reach the safe position.
In one embodiment, the control unit can communicate with a navigation system built in the vehicle and can determine an optimized safe location and/or an optimized driving route based on traffic density, road conditions, city functional blocks and/or remaining range of the vehicle.
The invention also proposes a vehicle, which is an autonomous vehicle, equipped with a safety system according to the invention.
In one embodiment, the vehicle is a diesel locomotive, a hybrid vehicle, a fuel cell vehicle, or a pure electric vehicle.
With the safety system according to the invention (or the vehicle having the safety system), in the event of a dangerous event (e.g. a fire or flood), the vehicle can be protected in a particularly advantageous manner against damage from the dangerous event, even in the event that communication with the internet is not available, and also against extensive damage caused by chain reactions.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
The expression "and/or" is used herein in the sense of including at least one of the components listed before and after the expression. As used herein, reference to "a component, step, operation, or element that" has, "includes," or "includes" means that at least one other component, step, operation, or element is present or added.
It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein generally includes motor vehicles, such as passenger vehicles including Sport Utility Vehicles (SUVs), buses, vans, various commercial vehicles, watercraft including various boats, ships, aircraft, and the like, and includes conventional diesel locomotives, hybrid vehicles, electric only vehicles, hydrogen powered vehicles, and other alternative fuel vehicles (e.g., fuels derived from sources other than petroleum).
Fig. 1 shows a block diagram of an embodiment of a security system according to the invention. The safety system 10 according to the invention for a vehicle comprises a sensor unit 2, an evaluation unit 4 and a control unit 6, wherein the vehicle is an autonomous vehicle. The sensor unit 2 is provided for detecting the surroundings of the vehicle. The evaluation unit 4 is provided to determine whether an external hazard event has occurred on the basis of the information received by the sensor unit 2 and to evaluate the location and the range of action of the external hazard event. The control unit 6 is provided for activating the automatic driving function of the vehicle and controlling the vehicle to automatically drive to a safe position outside the range of action of the external hazard event in case the analysis processing unit 4 determines that the external hazard event occurs.
FIG. 2 illustrates a block diagram of one embodiment of a vehicle 20 having the security system 10 shown in FIG. 1. In principle, the vehicle 20 is an autonomous vehicle. The vehicle 20 may be a diesel locomotive, a hybrid vehicle, a fuel cell vehicle, or a pure electric vehicle, according to the present invention.
Fig. 3 shows an exemplary application scenario of the vehicle 20 of fig. 2 having the safety system 10 of the present invention in the event of an external hazard. In the embodiment of fig. 3, the vehicle is, for example, parked in a parking lot, while the driver is not on site. Preferably, the security system 10 of the present invention is connectable not only to the power supply of the vehicle, but also to a separate power supply device. This ensures that the security system 10 operates reliably at all times. Preferably, when the vehicle 20 is parked in a parking lot (vehicle engine is stopped), the safety system 10 is connected to a power supply device that operates independently of the vehicle so as to detect the surroundings of the vehicle also when the vehicle is stopped. Preferably, the separate power supply means is integrated in the security system 10. In a preferred embodiment, the safety system 10 continuously performs real-time detection to ensure that the vehicle is in a safe environment. Alternatively, the safety system 10 detects at certain time intervals (e.g., 10 minutes or 30 minutes), thereby ensuring the safety of the vehicle in a more energy-saving manner; preferably, the time interval for detection can be individually adjusted by the user.
The external hazard event includes, for example: an external thermal event, a flood event, and/or a seismic event. The sensor unit 2 includes: smoke sensors, gas sensors, temperature sensors, infrared sensors, image sensors and/or sound sensors. In the embodiment shown in fig. 3, an external hazard event (an external thermal event in this embodiment) occurs, for example, with a vehicle 40 in the parking lot in the vicinity of the vehicle 20. In particular, the security system 10 can detect external thermal events of the nearby vehicle 40 via smoke sensors, temperature sensors, infrared sensors, and/or acoustic sensors. The analysis unit 4 of the safety system 10 can then carry out a comprehensive analysis process on the basis of the information received by the sensor unit 2, in order to determine that an external thermal event has occurred and to evaluate the location and the range of action, even the trend and the range of potential spread, of the external thermal event. Then, the control unit 6 activates the automatic driving function of the vehicle 20 and controls the vehicle 20 to automatically travel to the safe position 100 outside the range of action of the external dangerous event based on the result determined by the analysis processing unit 4. For example, if the analysis processing unit 4 finds, for example, that a fire has occurred in an underground two-story parking lot and is progressing to an underground one-story parking lot based on the infrared sensor and/or the image sensor and/or the temperature sensor and/or the smoke sensor, the control unit 6 specifies a place other than the building where the parking lot is located as a safe place (the safe place is preferably an area where people are less open) and activates the vehicle and controls the vehicle to automatically travel to the selected safe place.
In addition to external thermal events, such as fires, flood or seismic events can be detected by the sensor unit 2. For example, a parking lot flooding event caused by heavy rainstorms may be detected by an image sensor and/or a sound sensor. For example, seismic events may be detected by image sensors and/or acoustic sensors and/or vibration sensors. In one embodiment, the sensor unit 2 can identify a dangerous event by acquiring images and/or sounds in a building even in the case where there is no network signal in the underground parking lot; for example, in the case of receiving an evacuation broadcast in a building, "please note that an earthquake occurs in a local area, please leave to wait for a while", a "seismic event" is inferred; in the case where an image in which the sound "heavy rainstorm is received" and the water level exceeds a certain height is detected, a "flood event" is inferred. Preferably, the analysis unit 4 of the safety system 10 is able to perform a comprehensive analysis process on the information received by the sensor unit 2, in order to determine that an external hazard has occurred and to evaluate the location and the scope of action, even the trend and the range of potential spread, of the external hazard.
Preferably, in case the analysis processing unit 4 determines that an external dangerous event occurs, the control unit 6 controls the vehicle to sound a danger alarm and/or a danger alarm lamp. Alternatively or additionally, in case the analysis processing unit 4 determines that an external dangerous event occurs, the control unit 6 sends alarm information to the fire brigade. If there is no network signal, the control unit 6 first controls the vehicle 20 to leave the external hazard event, and does not send an alarm message to the fire department until a network signal is available.
Preferably, in case the analysis processing unit 4 determines that an external dangerous event occurs, the control unit 6 transmits alarm information to the owner of the vehicle 20. Preferably, the control unit 6 controls the vehicle 20 to automatically travel to a safe position confirmed by the owner of the vehicle. Particularly preferably, the control unit 6 selects a safe position 100 outside the scope of action of the external hazard event according to a predetermined strategy and controls the vehicle 20 to automatically drive to the safe position 100 without the confirmation of the owner of the vehicle. Preferably, the predetermined strategy may be, for example, leaving a parking lot where an external hazard event occurs, driving the vehicle to a parking location in an open area (preferably, these alternative open areas have been pre-stored in a navigation system built in the vehicle as alternative safe locations, for example). Preferably, after the network signal is available, the control unit 6 is able to adjust the selected safety position based on the information obtained from the network signal.
Preferably, the control unit 6 is able to communicate with a navigation system built into the vehicle 20 and is able to determine an optimized safe position and/or an optimized driving route depending on the traffic density, the road conditions, the city function block and/or the remaining cruising ability of the vehicle. In this way, the vehicle can advantageously be moved away from the external hazard event and to a safe location even in the temporary absence of a network signal. Preferably, the control unit 6 can select a route away from the source of the external hazard event to drive the vehicle 20 out of the parking lot. Preferably, the control unit 6 can select a route having a low traffic density at ordinary times to drive the vehicle 20 to the safe position 100 based on history data in the built-in navigation system. The control unit 6 preferably automatically drives the vehicle 20 to a safe location in an area such as a city leisure (e.g., a park) or a suburban area, instead of driving to an area such as a city business area or a residential area, thereby improving the safety of the evacuation route. Preferably, the control unit 6 selects the best safety position that is accessible from a plurality of alternative safety positions depending on the remaining range of the vehicle 20.
Preferably, after controlling the vehicle 20 to automatically travel to the safe position 100, the control unit 6 sends information to the owner of the vehicle 20 (e.g., to the owner's mobile terminal 200) to the safe position 100. Alternatively, after first evacuating the danger area, information can also be transmitted to the vehicle owner on the way to the safety location in order to receive further instructions from the vehicle owner. In a preferred embodiment, the owner of the vehicle 20 can remotely control the vehicle 20 to travel to a safe location via the mobile terminal 200 in the presence of the network signal.
In one embodiment, the vehicle 20 is a full electric vehicle. Pure electric vehicles are usually charged in parking lots by means of charging posts. If an external dangerous event (especially an external thermal event) occurs in the parking lot, the parking lot is very dangerous for pure electric vehicles (especially the pure electric vehicles which are being charged), and even a fire or an explosion can be caused. In case the analysis processing unit 4 determines that an external dangerous event occurs during the parking charging, the control unit 6 can interrupt the charging process and control the vehicle 20 to automatically travel to the safe position 100 according to the current state of charge (SOC). In the event of a shortage of charge, the control unit 6 can switch the charging process to a rapid charging mode, interrupt the charging process after the state of charge is sufficient to reach the selected safety position and control the vehicle 20 to automatically travel to the safety position 100.
The invention is not limited to the embodiments shown but comprises or extends to all technical equivalents that may fall within the scope and spirit of the appended claims. The positional references selected in the description, such as, for example, upper, lower, left, right, etc., refer to the direct description and to the illustrated drawings and can be transferred to new positions in the event of a change in position.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make variations and modifications of the present invention without departing from the spirit and scope of the present invention by using the methods and technical contents disclosed above.
