Description
Technical Field
The present invention relates to a safety system for a vehicle, and also relates to a vehicle having the safety system.
Background
Currently, autopilot technology is rapidly evolving. The automatic driving vehicle relies on cooperation of artificial intelligence, visual computing, monitoring device, global positioning system, etc., so that the computer can automatically and safely run the motor vehicle without any active operation of human beings.
The inventors of the present application propose: for example, in the event of an external dangerous event at a parking lot, a user typically cannot drive the vehicle away from the dangerous location because it is not on site, thereby causing economic loss; in particular, for example, in the case of fire or the like, the combustion or explosion of one vehicle may affect surrounding parked vehicles to cause serious chain reactions; thus, when an external dangerous event (e.g., fire or flood) is encountered, further economic losses and/or personnel damage can be avoided if the autonomous vehicle can accordingly operate automatically without being affected by the external dangerous event.

The object of the invention is to provide a safety system for a vehicle and a vehicle having the safety system, which enable the vehicle to be operated in an improved manner when an external dangerous event is encountered, so that the vehicle can be protected from the external dangerous event or is influenced as little as possible by the external event.
The above-mentioned task is achieved by a safety system for a vehicle according to the present invention, the vehicle being an autonomous drivable vehicle, the safety system comprising: a sensor unit for detecting an ambient environment of the vehicle; an analysis processing unit for determining whether an external dangerous event occurs or not and evaluating a location and an action range of the external dangerous event according to the information received by the sensor unit; 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 we often encounter situations where network signals are poor and communication with the internet is not available in underground parks or in remote areas, or where communication devices of parks are damaged and communication with the internet is not available in time in case of fire or flood. Even in this case, the invention protects the vehicle 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 dangerous event, the specific location, the range of action, and even the trend thereof, of the dangerous event are evaluated and analyzed, while the vehicle is automatically driven into a safety location outside the range and/or the range of the trend of the dangerous event according to the electronic map of the vehicle navigation system itself.
The concept of an autonomous vehicle according to the invention is to be understood as meaning that the vehicle can be guided automatically in the longitudinal direction and in the transverse direction or autonomous driving with automated longitudinal and transverse direction. In the case of a driver-free driving, the vehicle can automatically complete the driving in all cases during the entire driving period, and can also automatically find a suitable parking space or charging stake. Currently, autopilot technology is rapidly evolving. The automatic driving vehicle relies on cooperation of artificial intelligence, visual computing, monitoring device, global positioning system, etc., so that the computer can automatically and safely run the motor vehicle without any active operation of human beings.
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 comprises: smoke sensors, gas sensors, temperature sensors, infrared sensors, image sensors, and/or sound sensors.
In a specific 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 vehicle owner. Alternatively, the control unit selects a safe position outside the range of action of the external hazard event according to a predetermined strategy without confirmation by the vehicle owner and controls the vehicle to automatically travel to the safe position.
In a specific embodiment, the control unit sends an alarm message to the fire department in case the analysis processing unit determines that an external hazard event has occurred. Alternatively or additionally, the control unit controls the vehicle to sound a hazard warning and/or a hazard warning light in case the analysis processing unit determines that an external hazard event has occurred.
In one embodiment, the control unit sends information to the vehicle owner of the vehicle to the safe location after controlling the vehicle to automatically travel to the safe location.
In one embodiment, the safety system is connectable to a vehicle power source and to a separate power source device.
In a specific 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 case of a shortage of electric power, the control unit can switch the charging process to the quick charging mode and interrupt the charging process and control the vehicle to automatically travel to the safe position after the state of charge is sufficient to reach the safe position.
In a specific 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 according to traffic density, road conditions, city functional blocks and/or vehicle remaining endurance.
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 an internal combustion locomotive, a hybrid vehicle, a fuel cell vehicle, or a pure electric vehicle.
With the safety system according to the invention (or the vehicle with the safety system), in the event of a dangerous event (for example a fire or flood), the vehicle is protected in a particularly advantageous manner from the dangerous event and also from the extensive damage caused by the chain reaction, even in the event of communication with the internet being unavailable.

Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than those herein described, and those skilled in the art may readily devise numerous other arrangements that do not depart from the spirit of the invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
The expression "and/or" as used herein is meant to include at least one of the components listed before and after the expression. As used herein, the meaning of a component, step, operation, and element in reference to "having," "including," or "comprising" means that at least one other component, step, operation, and element is present or added.
It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein generally include motor vehicles, such as passenger vehicles including Sport Utility Vehicles (SUVs), buses, vans, various commercial vehicles, boats including boats, ships, aircraft, etc., and include 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 one embodiment of a security system according to the invention. The safety system 10 according to the invention for a vehicle, which is an autonomous vehicle, comprises a sensor unit 2, an evaluation unit 4 and a control unit 6. The sensor unit 2 is arranged to detect the surroundings of the vehicle. The analysis processing unit 4 is arranged to determine from the information received by the sensor unit 2 whether an external dangerous event has occurred and to evaluate the location and the scope of action of the external dangerous event. The control unit 6 is arranged to activate the automatic driving function of the vehicle and to control the vehicle to automatically travel to a safe position outside the range of action of the external dangerous event in case the analysis processing unit 4 determines that an external dangerous event has occurred.
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. According to the present invention, the vehicle 20 may be an internal combustion locomotive, a hybrid vehicle, a fuel cell vehicle, or a pure electric vehicle.
FIG. 3 illustrates an exemplary application scenario of the vehicle 20 of FIG. 2 having the safety system 10 of the present invention upon encountering an external hazard event. In the embodiment of fig. 3, the vehicle is parked in a parking lot, for example, while the driver is not on site. Preferably, the safety 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. Thereby, it is ensured that the safety system 10 can reliably operate at any time. Preferably, the safety system 10 is connected to a power supply device that operates independently of the vehicle when the vehicle 20 is parked in a parking lot (the vehicle engine is stopped), so that the surroundings of the vehicle can be detected also when the vehicle is stopped. Preferably, the separate power supply device is integrated in the safety system 10. In a preferred embodiment, the safety system 10 continuously detects in real time 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-efficient manner; preferably, the time interval for detection can be personalized by the user.
The external dangerous event includes, for example: external thermal events, flood events, and/or seismic events. 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 dangerous event (in this embodiment, an external thermal event) occurs, for example, in the parking lot at a vehicle 40 in the vicinity of the vehicle 20. In particular, the safety system 10 can detect external thermal events of the nearby vehicle 40 via a smoke sensor, a temperature sensor, an infrared sensor, and/or a sound sensor. The analysis processing unit 4 of the safety system 10 can then perform an integrated 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, and even the trend and the potential sweep range, 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 hazard event based on the result determined by the analysis processing unit 4. For example, the analysis processing unit 4 derives from the infrared sensor and/or the image sensor and/or the temperature sensor and/or the smoke sensor that, for example, an underground two-storey parking garage is in a fire and is progressing to an underground one-storey parking garage, the control unit 6 predefines a place outside the building where the parking garage is located as a safe position (the safe position is preferably an area with little person) and activates the vehicle and controls the vehicle to automatically travel to the selected safe position.
In addition to external thermal events (e.g. fires), flood or seismic events can be detected by the sensor units 2. For example, a parking lot flooding event caused by heavy storm can be detected by an image sensor and/or a sound sensor. For example, the seismic event may be detected by an image sensor and/or a sound sensor and/or a vibration sensor. In one embodiment, the sensor unit 2 can identify dangerous events by capturing images and/or sounds in the building even in the absence of network signals in the underground parking garage; for example, in the case of receiving an evacuation broadcast in a building "please note that a local area is earthquake, please leave to the open place for waiting" temporarily, "a" seismic event "is inferred; in the case where the sound "heavy storm under" is received while an image in which the water level exceeds a certain height is detected, a "flood event" is inferred. Preferably, the analysis processing unit 4 of the safety system 10 is able to perform an integrated analysis process on the basis of the information received by the sensor unit 2, in order to determine that an external dangerous event has occurred and to evaluate the location and the scope of action, even the trend and the potential sweep range, of the external dangerous event.
Preferably, in case the analysis processing unit 4 determines that an external hazard event has occurred, the control unit 6 controls the vehicle to sound a hazard alarm and/or hazard lamps. Alternatively or additionally, in case the analysis processing unit 4 determines that an external dangerous event has occurred, the control unit 6 sends an alarm message to the fire department. If no network signal is available, the control unit 6 first controls the vehicle 20 to drive away from the external dangerous event, and does not send an alarm message to the fire department until the network signal is available.
Preferably, in case the analysis processing unit 4 determines that an external dangerous event has occurred, the control unit 6 sends an alarm message 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 vehicle owner. Particularly preferably, the control unit 6 selects a safe position 100 outside the range of action of the external hazard event according to a predetermined strategy without confirmation by the vehicle owner and controls the vehicle 20 to automatically travel to the safe position 100. Preferably, the predetermined strategy may be, for example, leaving a parking lot where an external dangerous event occurs, driving the vehicle to a parking location in an open area (preferably, these optional open areas are pre-stored in a navigation system built in the vehicle as optional safe locations, for example). Preferably, after the network signal is available, the control unit 6 is able to adjust the selected security location based on the information obtained by the network signal.
Preferably, the control unit 6 is able to communicate with a navigation system built into the vehicle 20 and to determine an optimized safe location and/or an optimized driving route depending on traffic density, road conditions, city functional blocks and/or vehicle remaining capacity. In this way, the vehicle can be moved away from an external dangerous event and to a safe location in an advantageous manner even in the temporary absence of a network signal. Preferably, the control unit 6 is able to take a route away from the source of the external dangerous event to drive the vehicle 20 out of the parking lot. Preferably, the control unit 6 is able to select a route with a low traffic density at ordinary times to drive the vehicle 20 to the safe location 100 based on the history data in the built-in navigation system. The control unit 6 preferably automatically drives the vehicle 20 to a safe location in a region such as a city leisure (e.g., park) or suburban area, rather than to a region such as a city business or residential area, thereby improving the safety of the evacuation route. Preferably, the control unit 6 selects the best safe position to reach from a plurality of alternative safe positions according to the remaining cruising ability of the vehicle 20.
Preferably, after controlling the vehicle 20 to automatically travel to the safe location 100, the control unit 6 transmits information to the safe location 100 to the owner of the vehicle 20 (e.g., to the owner's mobile terminal 200). Alternatively, after the dangerous area is first evacuated, information may be sent to the vehicle owner on the way to the safe 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 a safe location via the mobile terminal 200 in the presence of a network signal.
In one embodiment, the vehicle 20 is an electric only vehicle. Electric motor vehicles are usually charged in parking lots via charging posts. If an external dangerous event (especially an external thermal event) occurs in a parking lot, it is very dangerous for an electric-only vehicle (especially a charged electric-only vehicle), and even a fire or explosion may be caused. In the event that the analysis processing unit 4 determines that an external dangerous event has occurred during the parking charge, 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 case of a shortage of electric power, the control unit 6 can switch the charging process to a fast charging mode and interrupt the charging process and control the vehicle 20 to automatically travel to the safe position 100 after the state of charge is sufficient to reach the selected safe position.
The invention is not limited to the embodiments shown, but includes or extends to all technical equivalents which fall within the effective scope of the appended claims. The positional references selected in the description, such as, for example, up, down, left, right, etc., refer to the direct description and the drawings shown and can be transferred to new positions in the sense of a change in position.
Although the present invention has been described in terms of the preferred embodiments, it is not intended to be limited to the embodiments, and any person skilled in the art can make any possible variations and modifications to the technical solution of the present invention by using the methods and technical matters disclosed above without departing from the spirit and scope of the present invention, so any simple modifications, equivalent variations and modifications to the embodiments described above according to the technical matters of the present invention are within the scope of the technical matters of the present invention.
