Description of the drawings
The above-mentioned and/or additional aspect and advantage of the present invention will become in the description with reference to accompanying drawings below to embodiment
It is substantially and easy to understand, wherein：
Fig. 1 is the flow chart of brake hard based reminding method according to an embodiment of the invention；
Fig. 2 is the structured flowchart of brake hard alarm set according to an embodiment of the invention；Fig. 3 is according to the present invention
The schematic diagram of the brake hard alarm set of one embodiment.
Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from start to finish
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
Below in conjunction with Description of Drawings brake hard based reminding method, device and vehicle according to an embodiment of the invention.
Fig. 1 is the flow chart of brake hard based reminding method according to an embodiment of the invention.As shown in figure 1, according to this
The brake hard based reminding method of invention one embodiment, comprises the steps：
S101：Detection speed, and judge speed whether more than preset vehicle speed.
Then speed can calculate speed according to wheel speed signal, i.e., by the wheel speed signal of the wheel of reading vehicle：Adopt
The wheel speed signal of collection wheel, and speed is calculated according to the wheel speed signal of wheel.It is of course also possible to pass through velocity sensor directly examine
Measure, or the direct access from instrument.
Preset vehicle speed is to represent that vehicle is fast running or the marginal value for running at a low speed, that is to say, that if car
Speed is less than preset vehicle speed, then it is assumed that the travel speed of vehicle is slower, and speed is higher than after preset vehicle speed, it is believed that the traveling speed of vehicle
Degree is very fast.In a specific example of the present invention, preset vehicle speed is, for example, 40,000 ms/h.
It should be noted that preset vehicle speed is to represent that vehicle travels a marginal value of speed, therefore, however it is not limited to 40,000
M/h, can be for such as different running environment etc. with different values.
S102：Detection braking state, and judge whether on-position is emergency braking condition.
In the process of moving in case of emergency, driver is rapid, correctly using brake, in beeline for automobile
It is interior that car is stopped, referred to as brake hard.
Wherein, during driver's brake pedal, it is faster that speed changes, and represents that severity of braking is bigger, therefore, it can root
The speed changed according to speed or the size of severity of braking determine whether on-position is emergency braking condition.
By taking the size of severity of braking as an example, then detection braking state, and judge whether on-position is emergency braking condition
The step of include：The aperture of detection braking pedal, and the aperture rate of change of brake pedal is determined according to the aperture of brake pedal, with
And when the aperture rate of change for judging brake pedal is more than predetermined variation rate, judge that vehicle takes brake hard.Wherein, brake
The aperture rate of change of pedal can be presented as angle of brake pedal rate of change, for example：When angle of brake pedal rate of change is more than pre-
When determining rate of change, illustrate that severity of braking is very big, i.e., vehicle takes brake hard, in one embodiment of the invention, make a reservation for
Rate of change is but is not limited to 20 °s/sec.
By taking the speed of speed change as an example, then detection braking state, and judge whether on-position is emergency braking condition
The step of include：Detection braking deceleration, and when judging that braking deceleration is spent more than preset deceleration, judge that vehicle is taken tightly
It is anxious to brake.Wherein, in braking, it is faster that speed reduces, then illustrate that braking deceleration is bigger, therefore, it can in braking deceleration
When degree is spent more than preset deceleration, it is believed that vehicle takes brake hard.Wherein, preset deceleration degree can according to vehicle test or
It is empirically determined.
S103：If speed is more than preset vehicle speed and on-position is emergency braking condition, to occupant and periphery
Vehicle sends brake hard prompting.
For example：When 40,000 ms/h of speed ＞ and angle of brake pedal change >=20 °s/sec, then output order is to buzzing
Device and emergent display lamp, buzzer send prompt tone to point out occupant's vehicle now carrying out brake hard, meet an urgent need and indicate
Lamp works to point out nearby vehicle, and the vehicle should be noted to avoid for emergency braking condition.
It is understood that when speed is relatively low, 40,000 ms/h are less than such as, even if driver takes brake hard,
As speed is relatively low, the less harm to occupant of inertia is also less, meanwhile, nearby vehicle also has time enough to make to keep away
Allow, therefore, generally also avoid the need for sending brake hard prompting to occupant and nearby vehicle.
Brake hard based reminding method according to embodiments of the present invention, when speed is higher driver suddenly touches on the brake when, can touch
Send out such as in-car buzzer and emergent display lamp and send brake hard prompting to occupant and nearby vehicle, remind occupant and
Nearby vehicle notes, enables occupant to control the body of oneself in time, and nearby vehicle is carried out in time
Avoid, so as to reduce potential safety hazard, lift traffic safety.
Fig. 2 is the structured flowchart of brake hard alarm set according to an embodiment of the invention.As shown in Fig. 2 according to
The brake hard alarm set 200 of one embodiment of the invention, including：Reminiscences 210 and controller 220.
Wherein, reminiscences 210 are used for sending brake hard cue.Controller 220 is connected with reminiscences 210, is used for
Detection speed and on-position, and control reminds 210 when speed is more than preset vehicle speed and on-position is emergency braking condition
Device sends brake hard cue, to carry out brake hard prompting to occupant and nearby vehicle.
As shown in figure 3, in one embodiment of the invention, 220 (car body control module as shown in Figure 3 of controller
BCM, body control module) wheel of wheel (wheel 1 as shown in Figure 3, wheel 2, wheel 3 and wheel 4) can be gathered
Fast signal, and speed is calculated according to the wheel speed signal of wheel.
With reference to shown in Fig. 3, in one embodiment of the invention, controller 220 is used for opening for detection braking pedal 230
Degree, and the aperture rate of change of brake pedal 230 is determined according to the aperture of brake pedal 230, and judging brake pedal 230
Aperture rate of change be more than predetermined variation rate when, judge vehicle take brake hard.
In the other examples of the present invention, controller 220 with detection braking deceleration, and can judge braking deceleration
When degree is spent more than preset deceleration, judge that vehicle takes brake hard.
Further in conjunction with Fig. 3, reminiscences 210 include：Buzzer 211 and emergent display lamp 212, wherein, buzzer 211 is used for
Brake hard prompting is carried out to occupant.Emergent display lamp 212 is for carrying out brake hard prompting to nearby vehicle.
Brake hard alarm set according to embodiments of the present invention, when speed is higher driver suddenly touches on the brake when, can touch
Send out such as in-car buzzer and emergent display lamp and send brake hard prompting to occupant and nearby vehicle, remind occupant and
Nearby vehicle notes, enables occupant to control the body of oneself in time, and nearby vehicle is carried out in time
Avoid, so as to reduce potential safety hazard, lift traffic safety.
