Specific embodiment
Embodiments of the invention are described below in detail, the example of described embodiment is shown in the drawings, wherein identical from start to finish
Or the element that similar label represents same or similar element or has same or like function.Retouch below with reference to accompanying drawing
The embodiment stated is exemplary it is intended to be used for explaining the present invention, and is not considered as limiting the invention.
Below in conjunction with the tire pressure detection method of Description of Drawings vehicle according to embodiments of the present invention, system and vehicle.
Fig. 1 is the flow chart of the tire pressure detection method of vehicle according to an embodiment of the invention.As shown in figure 1, according to this
The tire pressure detection method of the vehicle of one embodiment of invention, comprises the steps：
S101：Judge whether vehicle is straight-line travelling according to multiple transverse accelerations of the vehicle detecting in first scheduled time
State.
Wherein, the transverse acceleration of vehicle points to heart acceleration, can be by the lateral acceleration sensor being arranged on vehicle
Detection obtains.As shown in Fig. 2 desiring to acceleration transducer the transverse acceleration of the vehicle collecting is sent to the dynamic of vehicle
Power is online (i.e.：CAN), by corresponding processing module (such as hanging over the corresponding controller on Power Environment Monitoring Network) to vehicle
Transverse acceleration processed.
Specifically, first pass through the transverse acceleration that lateral acceleration sensor detects vehicle in real time, then judge first
Whether multiple transverse accelerations of the vehicle being consecutively detected in the scheduled time are respectively less than the first predetermined acceleration, when judging first
When multiple transverse accelerations of the vehicle being consecutively detected in the scheduled time are respectively less than the first predetermined acceleration, judge vehicle as directly
Line transport condition, wherein, described first predetermined acceleration is [0m/s2, 0.3m/s2] between.
First predetermined acceleration can rule of thumb be worth to, and the first predetermined acceleration is a relatively small value, for example：Car
The transverse acceleration when turning for the speed is typically larger than the transverse acceleration in straight trip for the vehicle, theoretically, during vehicle straight trip
Transverse acceleration is zero, it is contemplated that practical situation, for keeping vehicle straight trip, driver is by carrying out micro- turn to steering wheel
Move to keep vehicle straight trip, now, can be along with less transverse acceleration occurs, therefore, the first predetermined acceleration is use
Small transverse acceleration that may be present when the transverse acceleration distinguishing Ackermann steer angle and vehicle straight trip.First makes a reservation for add
Speed is usually closer to zero.That is, when the transverse acceleration of vehicle is less than the first predetermined acceleration, even if laterally adding
Speed is not zero it is also possible to be ignored it is believed that being for keeping vehicle straight trip, turn small to steering wheel that driver takes
Dynamic lead to.
Therefore, if transverse acceleration in continuing for some time for the vehicle is all less (i.e.：Less than the first predetermined acceleration),
Then can be determined that vehicle is during this period of time in straight travel state.Specifically, the state of vehicle is the moment in traveling
Change, and on the basis of the premise of the method for the present invention is built upon the essentially linear traveling of automobile, due to vapour in reality
The traveling of car may have the situations such as turning, in order to prevent because the phenomenon such as turning causes the false alarm of method of the present invention generation,
Need to judge by the regular hour (i.e. first scheduled time), if the time is long, when tire pressure occurs abnormal not
Can reach and alarm purpose, the time is too short, and the method may be made false alarm, for example：If the time is too short,
Even if the transverse acceleration detecting within this time is respectively less than the first predetermined acceleration, also can not guarantee that vehicle is in
Straight-going state.According to the regulation of relevant laws and regulations, such as FMVSS138, SAE 21567, ISO 217150 and GB/T 26149
Etc. the regulation of regulation, tire pressure alarm time specifies within 20 minutes, that is, after there is abnormal tyre pressure, should be at 20 points
Reported to the police within clock, therefore, the present invention is accurate in order to judge to straight trip, and can reduce tire pressure alarm response as far as possible
Time, therefore, by first Preset Time select between [1 minute, 3 minutes], so, if 1 minute, 2 minutes or
In person 3 minutes, the transverse acceleration of vehicle persistently keeps relatively small, then can relatively accurately determine vehicle and be in straight trip
State, and, this time (first scheduled time) or the time more slightly longer than this time also can be to meet tire pressure report
Alert response time regulation.
S102：If vehicle is straight travel state, detects steering wheel turn signal further, and steering wheel is being detected
The persistent period to the first rotation direction steering wheel rotation is recorded during turn signal.
After determining that vehicle is in straight trip operating mode by S101, can be rotated according to steering wheel on the basis of vehicle straight trip
Signal record is to the persistent period of the first rotation direction steering wheel rotation.
Specifically, steering wheel turn signal includes steering wheel angle and steering wheel rotation direction, referring to Fig. 2, steering wheel angle
Can be collected by steering wheel angle sensor, and be sent on the Power Environment Monitoring Network of vehicle.In addition, can be according to steering wheel angle
Determine steering wheel rotation direction, for example：When steering wheel angle is negative, correspondence direction disk rotates counterclockwise, and works as steering wheel angle
Rotate clockwise for timing correspondence direction disk.
Therefore, in S102, the determination of persistent period can obtain in the following way：When steering wheel turn signal is detected, note
Record continues the very first time to the first rotation direction steering wheel rotation, and judges within the very first time, and whether steering wheel angle is equal
More than default corner, if it is, using the very first time as the persistent period.If that is, steering wheel be in all the time to
The state that one direction (as one of clockwise or counter-clockwise direction) rotates, then record to same direction rotation side
To the time of disk, and using this time as the persistent period.
In the examples described above, default corner can be [10 degree, 16 degree], specifically, driver drive when, even if car
It is in straight travel state, but driver is requisite for the fine setting of steering wheel, according to practical situation,
The angle of fine setting is typically small, and fine setting typically clockwise and counterclockwise is alternately, this be one relatively normal
Situation.But, if driver is not a relatively small angle and rotation direction is no longer handed over for the rotation of steering wheel
Replace, but steering wheel angle larger (as more than 10 degree) and be the rotation of single direction then it is assumed that now driver is for side
It is not normal situation to the operation of disk, at this time, it may be necessary to record the persistent period of this abnormal conditions.
So that steering wheel angle is 15 degree as a example, due to for most of automobiles, when tire on the drive wheels is (before two as precursor vehicle
Wheel) when pressure differential is larger and pressure differential keeps constant, in order to keep the car load can be with straight-line travelling, steering wheel needs to rotate one
Individual special angle.Because when steering tire has larger pressure differential, both sides tire centerline terrain clearance can be led to different, this
In the case of, if steering wheel is not suitably adjusted, then traveling can deviate straight line.Further, since different automobile types turn to
The number of degrees of disk corner corresponding tire corner are different, and 15 in the embodiment of the present invention degree determine under the following conditions, that is,：
When tire pressure more normal tire pressure in side is reduced more than 25% (scopes of rules and regulations), need larger to tire pressure by steering wheel
Tire side rotational angle just can maintain car load to move along a straight line more than 15 degree.
S103：When the persistent period being more than the second Preset Time, judge that tire pressure occurs abnormal and true according to the first rotation direction
Determine tire pressure and abnormal tire occurs.
Typically, because vehicle is when normal condition is kept straight on, general direction disk is shorter to the fine setting persistent period of single direction,
Therefore in order to avoid erroneous judgement, if the persistent period that steering wheel rotates to single direction longer (the such as larger than second Preset Time)
When then it is assumed that vehicle occur abnormal, that is, tire pressure occur abnormal.Wherein, the second Preset Time is, for example, [5 seconds, 15 seconds].Example
As：The time of 10 seconds can cover most situations, can effectively prevent the false alarm of tire pressure this period simultaneously.Tool
Say, if continuing the persistent period shorter (as 2 seconds) to single direction steering wheel rotation, possibly driver other side body
Normally finely tune to disk.If the time is longer, the response time that tire pressure is reported to the police may be affected, therefore, this time be limited
It is scheduled between 5 seconds to 15 seconds, not only can avoid false alarm, and the impact to the response time that tire pressure is reported to the police is less.
After judging that tire pressure occurs exception, can determine that tire pressure occurs abnormal tire according to the first rotation direction, specifically
Ground, if the first rotation direction is to rotate clockwise direction (i.e.：Persistently turn right steering wheel), then can be determined that vehicle
The near front wheel occur abnormal tyre pressure；If the first rotation direction is to rotate counterclockwise direction (i.e.：Persistently turn left steering wheel),
Then can determine that the off-front wheel of vehicle occurs abnormal tyre pressure.
S104：Occur abnormal tire to generate abnormal tyre pressure alarm signal according to tire pressure, reported to the police.For example：Work as the near front wheel
When under-voltage, can be shown by the middle control display screen of configuration on vehicle, or voice message is carried out by speaker, make driving
Member takes counter-measure in time, thus reducing tire risk of damage, lifts vehicle safety.
Further, in order to more accurately detect out whether tire pressure occurs exception, the method also includes：Detection power steering
Auxiliary signal, thus, judges that tire pressure occurs abnormal condition to further include：When the persistent period be more than the second Preset Time and
Sustainable existence power-assisted auxiliary signal in second Preset Time, then judge that tire pressure occurs abnormal.I.e.：If the side of normal condition
Rotate fine setting it may not be necessary to the auxiliary of power steering to disk, and continuing to rotate to direction and rotational angle is relatively large
When, usual power steering intervention, therefore, tire pressure can be lifted according to wrong power steering auxiliary signal abnormal detection occurs
Precision.In conjunction with shown in Fig. 2, power steering auxiliary signal is generated by servo steering system, and this can be believed by servo steering system
Number send to Power Environment Monitoring Network, this power steering auxiliary signal can be obtained on the net from power.
It should be noted that whether the tire pressure detection method of the vehicle of the embodiment of the present invention can owe to the driving wheel of precursor vehicle
