Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Existing vehicle driving system can not monitor the physical function situation of driver in real time, be in danger in driver
When state, active hedging can not be implemented.
Based on this, a kind of steering wheel and control loop provided in an embodiment of the present invention monitor driver's physical function in real time,
Early warning, active hedging are provided.
It is described in detail below by embodiment.
Fig. 1 is a kind of bogie arrangement schematic diagram provided in an embodiment of the present invention.
Referring to Fig.1, steering wheel includes turning to disc main body, the sensitive zones and controller turned on disc main body being arranged in；
Sensitive zones are connected with controller, for obtaining a variety of electro-physiological signals of driver so that controller according to
Electro-physiological signals know the physical function situation of driver, wherein sensitive zones are provided with multiple to be connected by conductive filament
The sensing unit of sensing network, sensing unit is respectively independent, specific as shown in Figure 2；
Specifically, by being provided with the electro-physiological signals of the steering wheel real-time monitoring driver of sensitive zones, controller root
The physical function situation of driver is known according to electro-physiological signals, and in the case where physical function situation is not suitable for driving, is executed
Corresponding operating realizes real time monitoring driver's physical function, provides early warning, the purpose of active hedging；
Wherein, sensitive zones can be integrated in the driver's grip portion for turning to disc main body or be sheathed on steering disc main body, when
For sensitive zones detachably when turning to disc main body, sensitive zones are the steering-wheel cover to match with the size for turning to disc main body；
Here, controller may be disposed at the other positions of the inside or vehicle that turn to disc main body；
Further, sensing unit is integrated with multiple sensors, and a variety of physiology of driver are obtained by multiple sensors
Electric signal, electro-physiological signals include heart rate electric signal, pulse electric signal, grip electric signal, temperature signal, in blood pressure electric signal
One or more；
Here, sensing unit is integrated with the sensor for being each responsible for monitoring above-mentioned a variety of electro-physiological signals, the class of sensor
Type multiplicity, including silicon capacitance integrated sensor, resonant transducer, surface acoustic wave sensor, thin film sensor, Fibre Optical Sensor
One or more of device, field-effect cast chemical sensor etc.；
Further, controller reaches for being compared a variety of electro-physiological signals with preset model in comparison result
Under preset condition, judge that physical function situation does not meet driving standard；
Here, the embodiment of the present invention pass through the electro-physiological signals model of a variety of electro-physiological signals and driver that will acquire into
Row compares, if the comparison situation of the two reaches preset condition, it is believed that the current physical function of driver is in tired shape
State is not suitable for driving；
Further, preset condition includes the physiology that the first default species number purpose electro-physiological signals are less than in preset model
The gap of electro-physiological signals in electric signal, at least one electro-physiological signals and preset model reaches preset range and when default
Second default species number purpose electro-physiological signals are less than the electro-physiological signals in preset model in long；
For example, 5 kinds of electro-physiological signals of current drivers have 4 kinds of lifes being less than in preset model compared with preset model
Electric signal is managed, at this point, current drivers are in a state of fatigue；If in a kind of electro-physiological signals of current drivers and preset model
Electro-physiological signals gap it is larger, which has been more than preset range, then current drivers are in a state of fatigue；If current drive
In 5 kinds of electro-physiological signals of person, there are 3 kinds of electro-physiological signals being less than in preset model, at this point, being lower than preset model physiology telecommunications
Number number do not reach the above-mentioned first 4 kinds of default type number, if but with 3 kinds be less than preset model in electro-physiological signals
State duration reach preset duration, then also judge that current drivers are in a state of fatigue；
It should be noted that when human body is in fatigue, pseudo- sleep state, heart rate electric signal, pulse electric signal, grip electricity
The signals such as signal, temperature signal, blood pressure electric signal are in lower plateau, therefore, when electro-physiological signals are lower than default
When model physiological electric signal, judge that current drivers are in a state of fatigue, wherein the embodiment of the present invention, which is able to detect driver, is
It is no to be in severe fatigue state, and operation of being braked or alarmed in time；
Further, controller is also used in the case where physical function situation does not meet driving standard, and control braking is set
Standby and emergency indicating equipment carries out corresponding operating；
Here, when judging the unsuitable driving of current drivers' physical function situation, controller controls braking equipment work,
It reduces speed now, and opens emergency indicating equipment, such as emergency light, until parking；
It further, further include that the identification authentication system turned on disc main body is set, for obtaining the identity of driver
Information, and judge according to identity information the identity account of driver；
Wherein, by identification authentication system or the identity of current drivers, i.e. current drivers are that daily vehicle uses
Person (car owner) still vehicle driver once in a while, the electro-physiological signals in driver's driving procedure store body corresponding with the driver
In part account；
Further, controller is also used to establish identity account according to identity information, and according to identity account, calling and body
The preset model that part account matches；
Here, for the identity identified for the first time, corresponding identity account is established, each identity account respectively corresponds one and drives
The identity for the person of sailing and a preset model established according to identity account；
Further, the history electro-physiological signals of acquisition of the preset model according to driver in driving procedure and/or with
The corresponding default physical function parameter of driver is established；
Wherein, preset model is pre- according to the history electro-physiological signals stored in corresponding identity account and/or with driver
The physical function parameter being first arranged is established；
Further, identification authentication system includes camera, fingerprint identification device, iris identification device, vena metacarpea identification
One or more of device；
Here, by above-mentioned identification authentication system identify driver biological characteristic, and then driver identity；
The embodiment of the present invention also provides a kind of control loop, including steering wheel as described above, further includes logical with steering wheel
The braking equipment and emergency indicating equipment for believing connection, the physical function situation of driver are monitored by steering wheel, in physical function
In the case that situation does not meet driving standard, control braking equipment and emergency indicating equipment work.
