When implementing, in vehicle travel process, it can be passed when driver holds the upper lid of steering wheel by pressure
Sensor detects the pressure signal of driver, then gets corresponding pressure value by the pressure signal.
Wherein, pressure sensor can obtain the pressure value currently gathered by below equation：
Wherein, PxThe pressure value currently gathered for pressure sensor, PMAXFor pressure
The default maximum pressure value of sensor, P0For the default initial pressure value of pressure sensor, V0For the corresponding voltage of initial pressure value
Value, VMAXFor the corresponding magnitude of voltage of maximum pressure value, VXThe corresponding electricity of pressure signal of some upper lid of steering wheel is held for driver
Pressure value.
As long as that is, pressure sensor, which is detected, pressure signal on steering wheel, you can according to above-mentioned calculation formula
Calculate the pressure value on current steering wheel.
It should be noted that different pressures sensor default maximum pressure value and maximum pressure value correspondence before dispatching from the factory
Magnitude of voltage, and initial pressure value and the corresponding magnitude of voltage of initial pressure value are all different.I.e. different types of pressure
Sensor has different maximum pressure values and initial pressure value, and corresponding magnitude of voltage respectively.
Step 402, the pressure value currently gathered according to N number of pressure sensor, determines the driving of driver currently in vehicle
Whether mode is dangerous, if dangerous, performs step 403, otherwise, any operation is not done.
Specifically, after pressure value on current steering wheel is determined, pressure sensor can lead to the pressure value information

Fig. 5 is the flow chart of the control method for vehicle of an alternative embodiment of the invention.
As shown in figure 5, the control method for vehicle can include following steps：
Step 501, in vehicle travel process, the pressure value that N number of pressure sensor is currently gathered is obtained.
Step 502, the pressure value currently gathered according to N number of pressure sensor, determine driver it is current whether the both hands side of holding
To disk, if it is not, step 503 is performed, if not performing any operation.
Specifically, in actual use, due to some drivers because personal bad steering custom, is commonly used
One hand carrys out steer direction disk, and buries potential safety hazard to vehicle is driven.In this regard, can be according to being set in steering wheel further groove in the application
Put pressure sensor detection upper lid on pressure value, come determine Current vehicle driver whether both hands steer direction disk.
When implementing, the pressure value that can be currently gathered according to N number of pressure sensor determines that each groove is corresponding respectively
Each current suffered pressure value of upper lid；If two upper current suffered pressure values of lid are all higher than threshold value；Then determine that driver works as
Preceding both hands hold steering wheel.
That is, being compared by the pressure value and predetermined threshold value for gathering pressure sensor, if on steering wheel
When the pressure value of certain two upper lids exceedes predetermined threshold value, you can it is both hands behaviour to determine the current drive manner of vehicle driver
Control or singlehanded manipulation.
It should be noted that in one embodiment of the invention, when vehicle is big in right-angled bend, or angle of turn
When, driver may need control direction disk to reverse big angle.At this moment the both hands of driver may be placed on certain of steering wheel
, can be according to the pressure value in some on steering wheel on lid, if more than default on one upper lid, then in this case
Second Threshold determine that driver is currently both hands manipulation or singlehanded steer direction disk.
Wherein, default Second Threshold is bigger than predetermined threshold value, such as 40N, 50N etc..
For example, however, it is determined that vehicle driver is currently applied to the pressure values on lid on certain two of steering wheel and is
25N, predetermined threshold value is 20N, then illustrates that the current drive manner of driver drives for both hands.
Or, however, it is determined that when the pressure value that vehicle driver is currently applied in some of steering wheel on lid is 45N, in advance
If threshold value is 40N, then illustrate that the current drive manner of driver drives for both hands.
Step 503, it is determined that current drive manner is dangerous.
Specifically, if it is determined that driver currently applies the pressure value covered on the steering wheel when being less than predetermined threshold value, then
It can determine that current drive manner is dangerous, then can be by display reminding word on instrument display screen, or send corresponding
Fault cues sound, to remind driver to use both hands steer direction disk.
Step 504, vehicle is controlled.
Control method for vehicle provided in an embodiment of the present invention, the pressure value gathered according to N number of pressure sensor, it is determined that driving
Member is current, and whether both hands hold steering wheel, if it is determined that when driver holds steering wheel currently without both hands, so that it may it is determined that current drives
Sail mode dangerous, then by instrument display screen to user's display reminding word, and corresponding fault cues sound is reported, to remind
Driver uses both hands steer direction disk.So as to ensure that the safety driven in vehicle processes.
By above-mentioned analysis, by the pressure sensor in steering wheel groove, vehicle driver holding side can detect
The pressure value of upper lid into disk, so as to determine whether the current drive manner of driver is dangerous according to pressure value.Due to it is determined that driving
Whether the current drive manner of the person of sailing is dangerous not only to include the mode that driver holds steering wheel, may also include the traveling speed of vehicle
Degree.With reference to Fig. 6, the control method for vehicle in the case of above-mentioned is specifically described.
Fig. 6 is the flow chart of the control method for vehicle of another embodiment of the present invention.
As shown in fig. 6, the control method for vehicle can include following steps：
Step 601, in vehicle travel process, the pressure value that N number of pressure sensor is currently gathered is obtained.
Step 602, the current travel speed of vehicle is obtained.
Specifically, the pressure sensor set in steering wheel, collects the driver's currently pressure of application on the steering wheel
After force value, blind controller system to can be sent pressure value by the form of electric signal.Blind controller system is according to the signal
Triggering obtains entire car controller, and (Vehicle Control Unit are referred to as：VCU the travel speed of Current vehicle in).
Step 603, the pressure value currently gathered according to current travel speed and N number of pressure sensor, determines driver
Whether current drive manner is dangerous, and step 604 is performed if dangerous, any operation is not otherwise performed.
If specifically, blind controller system, which receives entire car controller, passes through controller local area network (Controller
Area Network, referred to as：CAN) after the travel speed of the Current vehicle sent, it can come true first according to the speed of acquisition
It is fixed that whether the drive manner current to driver carries out judgement operation.
Wherein, if the travel speed of Current vehicle has exceeded pre-set velocity threshold value, the driving side current to driver
Formula is judged；Otherwise, without judging to operate.
In the present embodiment, pre-set velocity threshold value can be configured according to actual conditions, be not limited thereof herein.Than
Such as 5 kilometer per hours (km/h), 8km/h, 10km/h.
If for example, pre-set velocity threshold value is 8km/h, then when Vehicle Speed is less than or equal to 8km/h, then not
The drive manner current to driver judges.The electric signal transmitted to pressure sensor is without processing.
If Current vehicle travel speed is more than 8km/h, the drive manner current to driver judges, i.e. instrument
The electric signal that control system is transmitted to pressure sensor carries out processing operation, and the pressure value of combination pressure sensor collection, knows
The drive manner of other current driver's is both hands steer direction disk or singlehanded steer direction disk, or both hands off-direction disk.
Wherein, if being identified as both hands steer direction disk, then it represents that the drive manner safety of Current vehicle driver；If identification
For singlehanded steer direction disk, or both hands off-direction disk, then it represents that the drive manner of Current vehicle driver is dangerous.
When identifying that the current drive manner of driver is dangerous, then according to current Vehicle Speed and N number of pressure
The pressure value that sensor is currently gathered, determines the corresponding danger classes of the current drive manner of driver.
Wherein, danger classes may include that dangerous one-level, secondary threat and three-level are dangerous.
Step 604, vehicle is controlled.
Specifically, according to danger classes, vehicle is controlled using any one following mode：Reduce the power of vehicle
Export, be controlled to driver's transmission alert messages, the steering to steering wheel.
For example, if judge the drive manner of driver for one-level danger, instrument display screen display reminding text is passed through
Word " one hand holds steering wheel ", and send level fault prompt tone to driver.If detecting the pressure of two upper lids in the process
When force value is all higher than predetermined threshold value, the prompt text " one hand holds steering wheel " that is shown in instrument display screen disappears, while to driving
The level fault prompt tone that member sends also disappears.
And for example, if judge the drive manner of driver for three-level danger, the display reminding text on instrument display screen is passed through
Word " both hands off-direction disk ", and send three-level fault prompt tone to driver.Simultaneously to ensure the safety of driving, now vehicle
Controller controls the unpowered output of vehicle, slows down until vehicle stops.If detecting driver in the process holds steering wheel
The pressure values of certain two upper lids when being all higher than predetermined threshold value, prompt text " the both hands off-direction shown in instrument display screen
Disk " disappears, while the three-level fault prompt tone sent to driver also disappears.
It is opposite, in the process, if detect driver hold lid some on steering wheel pressure value exceeded it is pre-
If during threshold value, the prompt text " one hand holds steering wheel " shown in instrument display screen, and send level fault prompting to driver
Sound, output that vehicle control unit controls vehicle is still unpowered.
It is understood that when the drive manner for determining Current vehicle driver is dangerous, by instrument display screen
Outside upper display reminding word, the fault cues sound of corresponding harmful grade is also sent, and control vehicle whether there is power output,
To ensure the security in vehicle travel process.
In addition, in another embodiment of the present invention, the control method for vehicle, in addition to：
By setting heart rate sensor on the steering wheel, the current heart rate value of driver is obtained.
When it is determined that heart rate value is abnormal, reminder message is sent to driver.
Specifically, vehicle is being driven in the process of moving, if the heart rate that driver is held on steering wheel, steering wheel is passed
Sensor can obtain the current heart rate value of driver.Then the heart rate value got is sent to central control system (Electronic
