Further, in embodiments of the present invention, the physiological parameters may include any one or combination of more of the following parameters: heartbeat, blink frequency, pupil brightness degree, eye opening and closing degree, proportion of five eyes in face, visual axis direction, body temperature and tension of safety belts. The brightness degree of the pupil refers to the opening and closing size of the pupil, and the larger the pupil, the higher the brightness degree; the degree of opening and closing of the eye refers to the percentage of opening and closing of the eye relative to the normal state; the proportion of the five eyes of the face refers to the proportion of the corresponding parts of the face, the proportion of the five eyes of the face refers to the proportion of the length of the face, the length of the face is divided into three equal parts from the forehead hairline to the eyebrow bone, from the eyebrow bone to the nose bottom, from the nose bottom to the lower jaw, 1/3 which respectively accounts for the length of the face, the width of the five-eye face refers to the width proportion of the five equal parts by taking the length of the eye shape as a unit, and the five equal parts are formed from the left hairline. The visual axis direction refers to a line parallel to the visual angle direction of pupils of two eyes at the middle position of the two eyes, when a driver generally turns in a forward direction, the visual axis of the driver and the advancing direction of a vehicle can be in the same direction, when the vehicle is in a reverse working condition, the visual axis direction is generally in the direction of a left rear view mirror and a right rear view mirror, the visual axis direction needs to be judged by combining the actual working condition, when the driver moves in the forward direction, the visual axis direction generally meets the driving advancing direction, and when the vehicle is in a reverse state, the visual axis direction is generally in the direction of the left.
Specifically, an unsupervised learning deep learning method can be adopted, and the reasonable parameter range information of the physiological indexes of the driver is obtained through unsupervised learning of the physiological indexes of the driver, so that the driving parameter libraries corresponding to different scenes are generated by combining different driving scenes.
And S2, judging the state of the driver according to the at least one physiological parameter. Further, according to an embodiment of the present invention, determining the state of the driver according to the physiological parameter may include: and if at least one physiological parameter in the at least one physiological parameter is out of the preset normal range, judging that the state of the driver is abnormal.
And S3, triggering the vehicle to enter a corresponding driving mode according to the state of the driver.
Further, in the embodiment of the present invention, the driving mode includes a power mode and a comfort mode; triggering the vehicle to enter a corresponding driving mode according to the state of the driver may include: if the state of the driver is normal, keeping the current driving mode of the vehicle unchanged; and if the state of the driver is abnormal, triggering the vehicle to enter a comfortable mode so as to control the driving parameters.
Still further, according to an embodiment of the present invention, the driving parameters may include: a rate of change of acceleration and deceleration and/or a rate of change of steering angular velocity. The vehicle rear-end collision and the like caused by the over-quick acceleration or over-quick deceleration of the vehicle can be prevented by controlling the change rate of the acceleration and the deceleration, the vehicle skidding and the like caused by the over-quick turning of the vehicle can be prevented by controlling the change rate of the steering angle, and the running safety of the vehicle is ensured.
Specifically, the heartbeat of a driver can be detected by arranging a heart rate sensor on a safety belt of a vehicle or arranging a grip strength sensor on a steering wheel, the blinking frequency, the pupil brightness degree, the eye opening and closing degree, the proportion of five eyes in the face and the visual axis direction of the driver are detected by arranging a camera on the inner side of a left A column in the vehicle or the position of an interior lamp or the position of a windshield right facing the driver, the body temperature of the driver is detected by arranging a temperature sensor on the steering wheel, and the tension of the safety belt of the driver is detected by arranging a tension sensor.
When the vehicle runs, parameters of heartbeat, blink frequency, pupil brightness degree, eye opening and closing degree, proportion of five eyes in the face, visual axis direction, body temperature, tension of a safety belt and the like of a driver are acquired, and then whether the state of the driver is normal or not is judged according to the parameters. Generally, if the heartbeat is 70 to 120 beats/minute, the blink frequency is 10 to 20 beats/minute, the pupil brightness is 2 to 5mm, and the eye opening and closing degree is less than 40% [ the eye opening and closing degree can be detected by PERCLOS (Percentage of eye opening and closing over the pupII over Time, defined as the Time occupied by a certain proportion (70% or 80%) of the eyes in a unit Time) ], the proportion of facial tribes is 1/3, the proportion of five eyes is 1/5, the visual axis direction of the driver is the driving direction, the body temperature of the driver is in the normal body temperature range (for example, 36 to 37 ℃), and the tension of the safety belt is 0, the state of the driver can be judged to be normal. If any of the above parameters is not within the preset normal range, for example, if the human body is in a fatigue state, the body metabolism will be reduced, the body temperature will be reduced by about 0.5 ℃, and the body temperature is not within the preset normal range, the driver is judged to be in an abnormal state. When it is judged that the state of the driver is normal, the driving pattern and the driving parameters (for example, the rate of change of acceleration and deceleration and the rate of change of steering angular velocity) of the vehicle are not interfered with. When the state of the driver is abnormal, the vehicle is controlled to enter a comfortable driving mode according to the physiological state of the driver so as to control driving parameters, the change rate of acceleration and deceleration of the vehicle and the change rate of steering angular velocity are controlled within a proper range in the comfortable driving mode, the physiological indexes and the real-time state of the driver are adapted, the uncomfortable feeling of the driver, such as dizziness, nausea and the like, caused by sudden acceleration, deceleration or steering of the vehicle is avoided, and the accidents of rear-end collision, slipping and the like of the vehicle are avoided. Therefore, the vehicle adapts to people, and the driving safety is improved.
According to an embodiment of the present invention, the vehicle control method described above may further include: judging the abnormal category of the state of the driver according to at least one physiological parameter; and adjusting the state parameters of the air conditioner according to the abnormal category.
Further, according to an embodiment of the present invention, if the state of the driver is not normal, the vehicle control method may further include: and sending out a reminding signal.
Specifically, the driver's abnormal category can be judged from the heartbeat, the blink frequency, the pupil brightness degree, the eye opening and closing degree, the proportion of the five eyes in the face, the visual axis direction, the body temperature, the tension of the safety belt, and the like.
For example, if the heartbeat is higher than 120 times/minute, the brightness degree of the pupil is less than 2mm, and the blinking frequency is more than 20 times/minute, the three conditions can be satisfied simultaneously to judge that the driver is in an extremely excited state; if only the first two are satisfied, namely the heartbeat parameter is higher than 120 times/minute, the brightness degree of the pupil is less than 2mm, but the blink frequency change is not obvious, the driver can be judged to be angry; if only the tachycardia is (more than 120 times/minute) and the other two are not obviously changed, the driver can be judged to be in a hungry state, and then the general driver is easy to have a low blood sugar risk condition. Monitoring whether the driver is in a fatigue state by monitoring the blinking frequency, the degree of eye opening and closing and the change of the proportion of the three family eyes and the five eyes on the face, wherein if the blinking frequency is higher than 20 times per minute and the degree of eye opening and closing exceeds 40 percent and the proportion of the three family eyes and the five eyes is increased by more than 30 percent, the three parts simultaneously satisfy the condition that the driver is in extreme fatigue, and if the blinking frequency of the driver is higher than 20 times per minute or the degree of eye opening and closing exceeds or the proportion of the three family eyes and the five eyes is increased by more than 20 percentAnd 30% over, the driver has fatigue of different degrees. The driver is considered to be in an abnormal state when more than one three indexes of fatigue and anger are judged, the vehicle can only be in a comfortable driving mode when the driver is in the abnormal state, meanwhile, the driver is reminded in the modes of sound, vibration and the like, the driver is prevented from making improper driving operation, and the driving safety is improved. The change rate of the comfortable driving mode to the longitudinal acceleration and deceleration is limited to [ -3.5, 3.5 [ -3.5 [)]m/s2Within the range, the limit of the change rate of the steering angle speed is within 150 degrees/s, 4 wheels of asynchronous control parameters of the vehicle drifting are not allowed to appear in the parking state control, and an air conditioner and multimedia in the vehicle are in a temperature and music background which makes people feel comfortable. The control of the acceleration and deceleration can be realized by matching the ESP with a wheel speed sensor, obtaining the speed and acceleration information of the vehicle through the wheel speed value fed back by the wheel speed sensor, and controlling the pressure rise of a brake master cylinder and a wheel cylinder when the speed and the acceleration exceed the limit to limit the over-fast change of the vehicle speed, thereby realizing the speed acceleration control; the angular speed control is realized by matching the EPS with an angle sensor, the ESP can know the change rate of the angle through the change of the angle fed back by the angle sensor, and when the change rate of the angle exceeds the limit, the ESP realizes the control of the speed of the change of the angle by controlling the torque of a motor.
Wherein, if the driver is in an extremely excited state, the driver can easily make an extremely extreme driving control instruction, such as stepping on the accelerator suddenly, at this time, the speed of the whole vehicle can be controlled by controlling the change rate of the acceleration and deceleration of an Electronic Stability Program (ESP), the lateral Stability of the vehicle running can be controlled by controlling the change rate of the Steering angular speed of an Electric Power Steering (EPS), meanwhile, the driver is properly reminded, the vehicle control is directly intervened by sound, vibration reminding or an ECU, the sound reminding adopts an S-level alarm reminding mode required by an instrument, the alarm is 600 times per second, the vibration mode reminding adopts 600 times/S which are the same as the alarm frequency, the ECU can properly adjust the change rate of the acceleration and the deceleration of the vehicle and the change rate of the Steering angular speed, and the change rate of the acceleration and the deceleration is limited to-3.5, 3.5]m/s2Change in steering angular velocityThe rate is limited to 150 DEG/s or less.
If the driver is in an angry state, the driver may make inappropriate driving operations due to bad mood, such as a sudden throttle depression, a turning and steering wheel jerking, and the like, at which time, the driving mode of the vehicle is limited to a comfortable mode by an ECU (Electronic Control Unit), that is, the vehicle is not allowed to run in a sport mode, and the vehicle does not accelerate and suddenly turn even if the driver steps on the throttle or the steering wheel jerks. The rate of change of the motion pattern to longitudinal acceleration and deceleration is typically amplified to [ -9,9]m/s2Within the range, the change rate of the steering angular velocity is amplified to be within 800 degrees/s, 4 wheels of asynchronous control parameters of the vehicle drifting are not limited by parking state control, and an air conditioner and multimedia in the vehicle are in a temperature and music background which enable people to feel excited.
If the driver is in an extremely tired state, the ECU controls the vehicle to be in an un-startable state, and the driver is prohibited from starting the vehicle, so that the driving safety is improved. For the tiredness with a low degree, the ECU continuously reminds the driver through voice, and because the person is easy to be tired when the temperature is high, the air conditioner in the vehicle can be controlled to be turned on to blow cold air, so that the driver can keep clear and the air in the vehicle can be kept smooth. Meanwhile, continuously monitoring the blinking frequency, the eye opening and closing degree and the proportion change of five eyes in the face to judge whether the physiological parameters of the driver are normal or not, and if the physiological parameters are normal, keeping the current vehicle control state and the state of an air conditioner in the vehicle; if the physiological state of the driver is continuously monitored, the driver is reminded in an extremely tired way if the driver state is continuously developed towards the extremely tired state.
If the vehicle is in an emergency state, for example, the vehicle judges that other vehicles around the vehicle collide with the vehicle, the vehicle can emergently remind the driver to call the driver to concentrate attention by using sound, vibration, multimedia emergency pictures and the like, the limit of a comfortable mode is released, the limit values of speed, acceleration, angular speed and the like are cancelled, and the vehicle is out of danger as soon as possible; if the vehicle judges that the part of the vehicle has a fault, the vehicle needs to be controlled to stop at a safe position as soon as possible, and the risk caused by the out-of-control of the vehicle is avoided.
It can be understood that if the state of the driver is abnormal, besides the above-mentioned sound and vibration modes can be adopted to remind the driver, a display screen can be added at the rear windshield of the vehicle to externally indicate the driving state of the vehicle and the state information of the driver, so that the pedestrian can know the state of the vehicle, the driver can not be reminded suddenly when the vehicle is abnormal, and the stress and the panic of the pedestrian can not be caused.
According to the vehicle control method provided by the embodiment of the invention, at least one physiological parameter of the driver is obtained, the state of the driver is judged according to the at least one physiological parameter, and the vehicle is triggered to enter a corresponding driving mode according to the state of the driver. The method can control the driving mode according to the state of the driver so as to adapt to the physiological indexes and the real-time state of the driver, thereby not only realizing the adaptation of the vehicle to people, but also improving the driving safety.

The acquisition module 10 can detect the heartbeat of the driver by setting a heart rate sensor on the safety belt of the vehicle or setting a grip sensor on the steering wheel, detect the blinking frequency of the driver, the pupil brightness degree, the eye opening and closing degree, the proportion of five eyes in the face and the visual axis direction by setting a camera on the inner side of the left A column in the vehicle or the position of an interior lamp or at the position of the windshield right facing the driver, detect the body temperature of the driver by setting a temperature sensor on the steering wheel, and detect the tension of the safety belt of the driver by setting a tension sensor.
When the vehicle is running, the acquiring module 10 acquires parameters of the heartbeat, the blinking frequency, the pupil brightness degree, the eye opening and closing degree, the proportion of the five eyes in the face, the visual axis direction, the body temperature, the tension of the safety belt and the like of the driver, and then the judging module 20 judges whether the state of the driver is normal or not. Generally, if the heartbeat is 70 to 120 beats/minute, the blink frequency is 10 to 20 beats/minute, the pupil brightness is 2 to 5mm, and the eye opening and closing degree [ the eye opening and closing degree can be detected by PERCLOS (Percentage of eye closed over the pupil over Time, defined as the Time occupied by a certain proportion (70% or 80%) of the closed eyes in a unit Time ] is less than 40%, the proportion of face tribentil is 1/3, the proportion of five eyes is 1/5, the visual axis direction of the driver is the driving direction, the body temperature of the driver is in the normal body temperature range (for example, 36 to 37 ℃), and the tension of the safety belt is 0, the state of the driver can be judged to be normal. If any of the above parameters is not within the preset normal range, for example, if the human body is in a fatigue state, the body metabolism will be reduced, the body temperature will be reduced by about 0.5 ℃, and the body temperature is not within the preset normal range, the determining module 20 determines that the state of the driver is abnormal. When it is judged that the state of the driver is normal, the execution module 30 does not intervene on the driving parameters of the vehicle (for example, the rate of change of acceleration and deceleration and the rate of change of steering angular velocity). When the state of the driver is judged to be abnormal, the execution module 30 controls the driving parameters according to the physiological state of the driver, controls the vehicle to enter a comfortable driving mode, controls the change rate of the acceleration and deceleration of the vehicle and the change rate of the steering angular velocity in a proper range in the comfortable driving mode, adapts to the physiological indexes and the real-time state of the driver, avoids discomfort, such as dizziness, nausea and the like, brought to the driver by sudden acceleration, deceleration or steering of the vehicle, and avoids several accidents, such as rear-end collision, slipping and the like, of the vehicle. Therefore, the vehicle adapts to people, and the driving safety is improved.
