As shown in
The acquiring device 1 is configured to acquire the body state information of the driver. The body state information may include various types of information, such as: brain wave information of a human body, eye closing information of the human body, sound information of the human body, facial expression information of the human body, heartbeat information of the human body and the like. In order to obtain the above-described body state information, the acquiring device 1 may include detection devices corresponding to the above-described body state information, such as: a brain wave sensor, a camera, a heart rate sensor, a sound sensor and the like, which are not limited here. It should be noted that the acquiring device 1 may detect the body state information of the driver in real time and transmit the detected body state information to the processor 2, so that a judgment can be performed in real time and the security of the driver can be improved.
The processor 2 is configured to receive the body state information of the driver detected by the acquiring device 1 and to judge the body state information. In a case where the detected body state information is the body abnormality information, it is indicated that the present body state of the driver is not suitable for keeping driving, or that the driver loses ability or consciousness for controlling the vehicle, which is very dangerous. The judgment criteria of the body abnormality information may be varied depending on the different types of the detected body state information. For example, in a situation where it is detected that the eye closing time of the driver exceeds a preset time, for example, the preset time is 5 seconds, it is judged that the driver is in a fatigue driving state, which is very dangerous and is prone to traffic accidents, and emergency stop may be performed by the execution device 3. For another example, in a situation where the sound information of the driver is detected to be screaming sound information, it is judged that a danger occurs during the driving, and that the driver may lose control of the vehicle, which is very dangerous, and emergency control may be performed by the execution device 3. For still another example, in a situation where it is detected that the heart rate information of the driver exceeds a preset value, it is judged that the driver is very nervous or excited at this time and may lose the ability of controlling the vehicle, and emergency braking may be performed by the execution device 3. According to the above examples, the processor 2 is configured to judge whether the driver is in an abnormal driving state based on the body state information of the driver, and the judgment criteria can be specifically set according to the type of the body state information; once the present body state information of the driver is judged to be the body abnormality information, the processor 2 outputs the execution signal to control the execution device 3 to act, so as to ensure the security of the driver. It should be noted that the processor 2 may be a vehicle controller in the vehicle or a controller that is additionally added to the existing vehicle, and the specific structural form of the processor is not limited here.
The above-mentioned execution device 3 is configured to execute the corresponding security action according to the acquired execution signal, and the execution device 3 may be a plurality of structural components in the vehicle, such as a brake, a gasbag opener, an alarm and so on. The execution device 3 may automatically control the vehicle to issue an alarm to remind the driver, so as to ensure the driving security of the driver. In a situation where the above-mentioned execution device 3 receives the execution signal from the processor 2, the execution device 3 performs the corresponding security action such as braking, opening the gasbag, alarming or the like, which are not specifically limited heren.
Embodiments of the present disclosure provide the vehicle control system for driving security of the driver. In conventional technologies, the driver loses control of the vehicle often due to subjective reasons of the driver in driving while driving, causing a serious vehicle accident and seriously affecting the security of the society. Compared with the conventional technologies, the vehicle control system provided by the present application includes the acquiring device 1, the processor and the execution device; when the driver drives the vehicle, the acquiring device 1 may acquire the body state information of the driver, and send the body state information to the processor; the processor judges whether the body state information is the body abnormality information, and in a case where the body state information is the body abnormality information, the processor sends the execution signal to the execution device, and the execution device may execute the corresponding security action according to the execution signal, so that in a situation where the driver experiences a subjective uncontrollable phenomenon during driving, such as falling asleep, screaming or the like, the vehicle control system automatically controls the vehicle through the execution device, to ensure the security of the driver.
Besides detecting and judging the body state information of the driver, the above vehicle control system may also detect and determine a state information of the vehicle itself. As shown in
The above-described acquiring device 1 may be of various types, as shown in
For example, the sound detector 11 includes a device such as a microphone or the like to acquire the sound information of the driver. During the driving process of the vehicle, in a situation where the vehicle is in an emergency, the driver may scream and lose control of the vehicle; by the processor 2, it may be judged whether the sound information of the driver acquired by the sound detector 11 is abnormal state information, such as a screaming sound or the like; and the processor 2 may control the execution device 3 (for example, a brake) to execute a security action (for example, braking action) to reduce or avoid injuries or accidents.
For example, the face acquiring device 12 may include an image acquiring device, such as a camera, for acquiring the facial image information of a human face; by the processor 2, whether the state of the driver is normal may be analyzed based on the facial image information. For example, in a situation where an emergency occurs, the driver may cover the face with hand, or the facial expression of the driver may be fearsome. The processor 2 may compare the facial image information with a data base of abnormal facial image information; if the facial image information is found to be the abnormal state information, the processor 2 may control the execution device 3 to execute the security action, such as braking or the like, to ensure the security of the driver.
For example, the eyeball detector 13 is configured to detect eyeball information such as a closing state of the eyeball, a gazing direction of the eyeball and the like; and by the processor 2, whether the driving state of the driver is normal may be analyzed based on the eyeball information. For example, in a situation where the eye closing time indicated by the eyeball information is too long, it may be judged that the driver falls asleep; in a situation where the gazing direction of the eyeball indicated by the eyeball information is shifted for a long time, it may be judged that the attention of the driver is not concentrated on driving, so that the processor 2 can judge whether the eyeball information is the abnormal state information based on the condition of the eyeball information. In a situation where the eyeball information is determined as the abnormal state information, the execution device 3 may be controlled to execute the security action such as braking, alarming or the like, to ensure the security of the driver. The structural types of the eyeball detector 13 may be various. For example, the eyeball detector 13 may include an infrared light emitter and an eyeball position sensor, the infrared light emitter is configured to emit infrared light, and the eyeball position sensor includes an infrared light detector configured to receive the infrared light reflected by an eye (such as an eyeball and a cornea), so as to capture actions such as a position movement of the eyeball, eye blinking and eye closing, which are not specifically limited in the embodiments of the present disclosure.
The above-described acquiring device 1 may further include a brain wave detector 14 as shown in
The above-described vehicle detector 4 may be of various types in structure. For example, the vehicle detector 4 is provided at the vehicle. As shown in

The embodiments of the present disclosure are not limited thereto.
The execution device is shown in
For example, the processor 2 may be a central processing unit (CPU), a digital signal processor (DSP), or other forms of processor with data processing capability and/or program execution capability, such as a field programmable gate array (FPGA) or the like. For example, the central processing unit (CPU) may be an X86 or ARM architecture or the like. The processor may be a general purpose processor or a special purpose processor, and may control the execution device 3 to execute a desired function. For example, the gasbag opener includes a sensor, a gas generator, a gasbag and a controller. The sensor is configured to sense a degree of collision of the vehicle and send a signal to the controller. The controller is configured to process the signal and send a signal to trigger the gas generator in a situation where it is determined that it is necessary to open the gasbag. The gas generator is configured to quickly ignite and generate a large amount of gas to inflate the gasbag, so as to open the gasbag.
For example, the glass breaker may be a tool that can be used to break the glass of the window of the vehicle, such as a glass puncher, a glass cutter, a security hammer, or the like.
For example, the vehicle control system further includes a memory for storing computer-readable instructions (e.g., one or more computer program modules) non-transiently, and the computer-readable instructions may be run by the processor to control the execution device 3 to execute a desired action. The memory and processor may be interconnected via a bus system and/or other form of connection mechanism (not shown).
Embodiments of the present disclosure also provide a vehicle including the vehicle control system described above.
Embodiments of the present disclosure provide a vehicle for protecting the driving security of the driver. In conventional technologies, the driver often loses control of the vehicle while driving due to subjective reasons, causing a serious vehicle accident and seriously affecting the security of the society. The vehicle provided by the embodiments of the present disclosure includes an acquiring device, a processor and an execution device. during the driving process that the driver drives the vehicle, the acquiring device may acquire a body state information of the driver, and send the body state information to the processor; the processor judges whether the body state information is body abnormality information, and sends an execution signal to the execution device in a case where the body state information is the body abnormality information; the execution device may execute a corresponding security action according to the execution signal, so that in a situation where the driver experiences a subjective uncontrollable phenomenon during driving, such as falling asleep, screaming or the like, the vehicle control system automatically can control the vehicle through the execution device, to ensure the security of the driver.
As shown in
The body state information can reflect the body condition of the driver, so as to know whether the driver still has an ability to control the vehicle. If the driver may be unable to control the vehicle, it can be regarded as the abnormal driving state. The abnormal driving state may have a variety of types, for example: the driver's brain wave is disordered, the driver's heart rate is too fast, the driver closes the eye for a long time, the driver shifts the line of sight for a long time, the driver screams, the driver's face is fearsome, etc., which can all be used as the judgment criteria for the abnormal driving information. If the body state information of the driver is the abnormal driving information, the vehicle may be controlled to execute the corresponding security action, such as: deceleration, braking, alarming, opening the gasbag or the like, so as to reduce or avoid injury to the driver.
Embodiments of the present disclosure provide the vehicle control method for driving security of the driver. In conventional technologies, the driver often loses control of the vehicle often due to subjective reasons of the driver in driving, causing a serious vehicle accident and seriously affecting the security of the society. Compared with the conventional technologies, the vehicle control method provided by the present application includes: first, acquiring the body state information of the driver, and then judging whether the body state information is the abnormal driving information, and controlling the vehicle to execute the corresponding security action if the body state information is the abnormal driving information, so that in a situation where the driver experiences a subjective runaway phenomenon during driving, such as falling asleep, screaming or the like, the vehicle control system automatically controls the vehicle to execute the security action, to ensure the security of the driver.
For example, as shown in
It can be seen that, in addition to judging based on the body state information of the human body, it is also possible to judge a state of the vehicle based on the vehicle state information; even if the body state information of the human body is normal, the vehicle is also controlled to execute the corresponding security action if the vehicle state information is the abnormal vehicle information, which is beneficial to further improving the security of driving the vehicle.
For example, the vehicle state information may also be various, such as collision information of the vehicle, vibration information of the vehicle, tilt angle information of the vehicle, water pressure information of the outer part of the vehicle and the like, which may all be used as the vehicle state information. The abnormal vehicle information involves a situation that the vehicle state information is abnormal, and the situation is that, for example: collision occurs to the vehicle, the vibration amplitude of the vehicle is large, the tilt angle of the vehicle is large, or the water pressure at the outer part of the vehicle is large; in this situation, the vehicle may be controlled to execute the corresponding security action, and the detailed of the actions are described in detail in the above embodiments and are not described here.
