Specific embodiment
For solving the above-mentioned problems in the prior art, the technical scheme that the embodiment of the present invention adopts is passed through
Obtain and record the impact aging ageing management parameter of pedal in real time, it is possible to achieve to pedal aging with
Track and detection, improve the safety of driving.
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings
The specific embodiment of the present invention is described in detail.
The flow chart that Fig. 1 shows the aging monitoring method of one of embodiment of the present invention pedal.As Fig. 1
The aging monitoring method of shown pedal, can include：
Step S101：The ageing management parameter of described pedal during Real-time Collection registration of vehicle use
Information；
Step S102：The information of the pedal ageing management parameter according to described acquisition, draws corresponding pedal
The information of current degree of aging；
Step S103：When the current degree of aging being drawn reaches default degree of aging threshold value, output
Change the information of pedal.
Below in conjunction with Fig. 2 and specific embodiment to the aging monitoring method of pedal of the present invention to detailed further
Thin introduction.
The flow chart that Fig. 2 shows the aging monitoring method of one of embodiment of the present invention pedal.As Fig. 2
The aging monitoring method of shown pedal, can include：
Step S201：The ageing management parameter of described pedal during Real-time Collection registration of vehicle use
Information.
In being embodied as, can constantly carry out the aging inspection of pedal in the whole life cycle of vehicle
Survey gathering and recording of parameter.
In an embodiment of the present invention, described ageing management parameter includes trampling number of times.When pedal position
Percentage signal more than 5%, then will be trampled number of times and add 1.Wherein, the percentage signal of pedal position adopts
Formula below is calculated：
β=DX-D0/DE-D0；
Wherein, β represents the percentage signal of brake pedal position, DXRepresent that pedal position sensor is read
The A/D conversion value when pedal current location taking, D0At the beginning of the pedal travel that expression system self study obtains
The A/D conversion value of beginning position, DERepresent the final position corresponding A/D conversion value of pedal travel.
In being embodied as, when pedal is in use because mechanical wear etc. causes initial position to deviate
During initial position when vehicle is offline, the number of times under being trampled with pedal is when with reference to so that drawn
Pedal degree of aging testing result is more accurate.
In an embodiment of the present invention, described ageing management parameter includes trampling that position is interval corresponding tramples
Number of times.Wherein, pedal by trample reach to trample position interval, include first trample position interval, the
Two trample that position is interval and the 3rd to trample position interval, and described first to trample position interval be 5%-30%,
Described second to trample position interval be 30%-50%, and the described 3rd to trample position interval be 50%-100%,
Specifically refer to table 1.
Table 1
When the position that pedal is trampled falls into when trampling in the interval range of position of 5%-30%, can be by first
Record numerical value increase is once；Trample position interval range when what the position that pedal is trampled fell into 30%-50%
When interior, can by the second record numerical value increase once, when the position that pedal is trampled falls into 50%-100%'s
When trampling in the interval range of position, can by the 3rd record numerical value increase once.
It has been investigated that, the degree (trampling position) of trampling of each pedal has directly to the aging of pedal
Impact, therefore by recording to the interval number of times in position of trampling that position falls into of trampling of pedal, can
There is provided strong reference with the monitoring of the degree of aging as pedal.
In an embodiment of the present invention, described ageing management parameter includes VMT Vehicle-Miles of Travel number.Vehicle
Distance travelled number can reflect the service condition of vehicle to a certain extent, accelerates the aging of brake pedal.
Using the distance travelled of vehicle as the aging detection parameter of pedal, can analyze for pedal degree of aging provides
Strong reference.
Step S202：According to the current ageing management parameter of acquired pedal, inquire about pedal aging curve,
Draw the information of the current degree of aging of corresponding pedal.
In being embodied as, pedal aging curve is to carry out train experiment to pedal to draw, including stepping on
Plate ageing management parameter and the corresponding relation of degree of aging.Shown in Figure 3, implement in the present invention one
In example, described pedal aging curve includes trampling number of times and pedal deflection amount, and (described pedal deflection amount is to step on
The percentage ratio of the current zero degree position in static state for the plate and the initial zero degree position of pedal) between corresponding pass
System.Therefore, get pedal trample number of times after, by inquire about described pedal aging curve just may be used
To immediately arrive at pedal deflection amount, i.e. the result of the degree of aging of pedal.
Step S203：Judge whether the current degree of aging being drawn reaches default degree of aging threshold value,
When judged result is to be, can be with execution step S204, conversely, then not executing any operation.In tool
During body is implemented, described default degree of aging threshold value, i.e. default pedal deflection amount, can be according to reality
Needs be configured.For example, the vehicle of the type of pedal, and pedal application is different, default old
Change degree threshold value also will have a certain degree of difference.
Step S204：The information of pedal is changed in output.In being embodied as, in being embodied as,
When vehicle driver's pushes pedals, electronic control unit (Electronic Control Unit, ECU) meeting
The pedal position that Linear pedal sensor is gathered is processed and is sent to his control unit, to enter
The control of driving.When analysis draws the current degree of aging of the pedal of vehicle, i.e. pedal deflection amount, reach
To or when exceeding default degree of aging threshold value, electronic control unit is according to the pedal position letter being gathered
Number with actual position signalling, larger deviation will occur, so that other control unit is according to institute
The control signal of the pedal position output of collection occurs larger deviation, thus may result in vehicle thing
Therefore generation, there is larger danger.
Therefore, when the current pedal degree of aging of vehicle reaches default degree of aging threshold value, can be defeated
Go out the corresponding information changing pedal, with to vehicle driver to point out so that vehicle driver can
Change pedal with timely, thus the safety of driving can be improved.
