Each status information includes the alarm condition accordingly alarmed and display state.
M alarm has different display priority, can be indicated by the sequence in alarm state information list, can also
To be indicated by the way that display priority is added in alarm state information list.
In the present embodiment, different display priority is indicated using the sequence in alarm state information list.
The alarm condition that controller can be alarmed by wired connection or wireless connection acquisition, wired connection, such as cable,
Bus, instrument controller obtains the alarm condition of alarm by CAN bus in the present embodiment, such as receives tire pressure management system
Warning message (tire pressure is too low).
Alarm condition be it is on and off, opening refer to state of activation, such as when tire pressure is too low tire pressure it is too low alarm swash
It is living, the too low bell character of bell character 31- tire pressureIt lights, some tire pressure that user can perceive current vehicle is too low.
Controller further includes first timer, is provided for the display cycle T1 in alarm indication region 3, alarm indication area
Domain 3 updates alarm indication every display cycle T1.
Display state includes the first display state D1, the second display state D2, the third display of display state D3 and the 4th
State D4, the first display state D1 indicate that, without display (alarm condition is to close), the second display state D2 expression is being alarmed
Information display area 3 shows that third shows that state D3 expression at least showed a display cycle T1 but do not showed currently, the 4th
Display state D4 indicates to need to show but do not showed.
If display cycle T1 reaches,
Third, which is set, by the display state for the alarm that display state is the second display state D2 shows state D3；
Set available for N number of display position.
If display cycle T1 is not reached,
If the alarm condition of alarm changes,
Zero updates corresponding alarm condition in warning message list；
Zero for changing to open alarm from closing, and it is the 4th display state that its display state, which is arranged,；
Zero for from the alarm for changing to closing is opened, it is the first display state that its display state, which is arranged, if it shows
State is the second display state, updates the alarm indication in alarm indication region；
It is the alarm of the 4th display state if there is display state,
If there are available display positions in zero alarm indication region, the alarm indication in alarm indication region is updated；
If available display position is not present in zero alarm indication region, there are following alarms: its display priority is higher than institute
Having display state is the alarm of the second display state, updates the alarm indication in alarm indication region；
It is the 4th display state by the alarm setting that third shows state if there is no the alarm of the 4th display state.
Controller can obtain the alarm condition variation of alarm by various modes, such as receive report by CAN bus
The alert message opened/closed obtains the alarm condition variation of alarm, alarm signal can also be obtained by cable, to obtain
The alarm condition of alarm changes, the invention is not limited in this regard.
When display cycle T1 is not reached, above-mentioned processing is carried out, can be timely updated in the alarm condition variation for obtaining alarm
The alarm indication in alarm indication region, makes user perceive vehicle-state in time.
For from close change to open alarm, be arranged its display state be the 4th display state D4 (need show but
It did not showed).
It is the first display state D1 (without display) for its display state from the alarm for changing to closing is opened, is arranged,
If it shows that state is the second display state D2 (just showing in warning message display area 3), alarm indication region 3 is updated
Alarm indication can show the alarm of other openings using the display position vacated in time.
For the case where there are the alarms that display state is the 4th display state D4 (needing to show but do not showed): if
There are available display positions in alarm indication region 3, update the alarm indication in alarm indication region 3, make full use of limited display
The alarm that position display is more opened.
For the case where there are the alarms that display state is the 4th display state D4 (needing to show but do not showed): if
Available display position is not present in alarm indication region 3, but there are following alarms: its display priority is higher than all display states and is
The alarm of second display state D2, updates the alarm indication in alarm indication region, to guarantee that the alarm of display priority is shown early
Show.
If there is no the alarm of the 4th display state D4 (needing to show but do not showed), i.e., the alarm of all openings is equal
It showed, and all thirds was shown that the alarm setting of state D3 was the 4th display state D4 at this time, that is, remove original display
State is re-set as needing state to be shown.
As shown in Fig. 4 A, 4B, preceding 8 alarms are opened, when the alarm of all openings was shown, the displays of this 8 alarms
State is that third shows state D3, sets the 4th display state D4 for the display state that this 8 are alarmed at this time, it is aobvious to update alarm
Preceding 6 alarms can be shown when showing, display state is set as the second display state D2, as shown in Figure 4 A.
When updating next time, the display state of preceding 6 alarms is set as third and shows state D3, after alarm indication can be shown
2 alarms (display state be set as the 4th display state D4), as shown in Figure 4 B, display states of the two alarms are set as the
Two display state D2.
When updating again, the display states of this 8 alarms are that third shows state D3, and such alarm indication region can be
Two interfaces as shown in Fig. 4 A, 4B alternately display.
For the alarm display apparatus of the present embodiment, detailed process such as Fig. 5 institute of alarm indication is adjusted according to status information
Show；The alarm indication for updating alarm indication region 3, as shown in the part in Fig. 5 in dashed box, comprising the following steps:
The 4th display state D4 is set by the display state for the alarm that display state is the second display state D2；
It is opening, at most 6 highest alarms of display priority that alarm condition is chosen in warning message list；
The alarm of selection is shown in alarm indication region 3, and sets the second display state D2 for display state；
Start first timer.
As soon as being refreshed if a bell character is just shown, it may appear that the problem of bell character flashes, alarm flashing, and
This flicker frequency is not Guaranteed in design, causes user that can not correctly read warning information by human eye, influences user
Identification to bell character, so as to influence perception of the user to alarm.
In another embodiment, controller further includes N number of second timer, such as 6, is provided for alarm indication
The flashing protection period T2 in region, such as be set as 1 second, each second timer corresponds to a display position.Specifically, second
Timer initial value is timer maximum, and when new alarm occurs in corresponding display position, second timer resets to 0, and opens
Beginning timing is until reaching timing maximum value, and such as 1 second.The position can just be refreshed after reaching maximum value, be somebody's turn to do once display refreshes
Timer resets to 0 again.As long as the alarm shown at least shows a flashing protection period T2 period, that is, passes through
It crosses flashing protection period T2 to refresh again, it will be able to avoid flashing
It is the first display state that its display state is arranged if the time that the alarm has shown that T2, and updates alarm signal
Breath display；Otherwise waiting for the T2 time reaches more new state and display again.The problem of avoiding the occurrence of bell character flashing, influences to use
Identification of the family to bell character, so as to influence perception of the user to alarm.
Although the present invention has been disclosed in the preferred embodiments as above, present invention is not limited to this.Any art technology
Personnel, made various changes and modification, should all be included in protection model of the invention without departing from the spirit and scope of the present invention
In enclosing, therefore protection scope of the present invention should be defined by the scope defined by the claims..
