Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In one embodiment, as shown in fig. 1, a method for reducing the response latency of the vehicle-mounted device is provided, which comprises the following steps S10-S40.
And S10, acquiring the electric quantity information of the vehicle-mounted storage battery and the specified standby power consumption information of the vehicle-mounted equipment.
Understandably, the vehicle-mounted battery capacity information includes, but is not limited to, total battery capacity, current battery capacity, and reserved capacity ratio. Here, the battery supplies both the vehicle-mounted device and the vehicle starting system. The reserve charge ratio refers to the ratio of the charge reserved for the vehicle starting system. If the electric quantity of the storage battery is insufficient, the automobile can not be started normally. The reserved electric quantity proportion can be set according to actual needs, such as 30%.
The vehicle-mounted equipment can refer to electronic equipment on a vehicle, such as a vehicle event data recorder, a sound entertainment host and the like. The vehicle-mounted device can have a plurality of operating modes, such as an operating mode, a sleep mode, a standby mode, a quasi-standby mode (Suspend to RAM), and the like. The specified standby power consumption information may be power consumption data of the in-vehicle apparatus in the specified standby state. Here, the power consumption data may refer to power consumption or current consumption. The specified standby state may be a state of the in-vehicle apparatus in a standby mode or a quasi-standby mode.
In some examples, the operation mode refers to a configuration mode when the vehicle-mounted device is normally operated, and in this mode, components of the vehicle-mounted device, such as a host chip, a display, a loudspeaker, a microphone and the like, are all in an operation state. The sleep mode refers to a configuration mode when the vehicle-mounted device stops operating, in which each component of the vehicle-mounted device is in a sleep state. The standby mode refers to a configuration mode when the in-vehicle apparatus section components stop operating, in which mode the speaker, display, microphone, and the like are in a sleep state and the host chip is still operating normally. The quasi-standby mode refers to a configuration mode in which the in-vehicle device turns off a speaker, a display, a microphone, and the like, and the host chip operates in a low power mode in which operation data of the host chip can be stored in the memory.
And S20, determining the allowed specified standby time of the vehicle-mounted equipment according to the vehicle-mounted storage battery electric quantity information and the specified standby power consumption information.
Understandably, the available power of the vehicle-mounted device can be calculated according to the vehicle-mounted storage battery power information, and the standby power (or quasi standby power) of the vehicle-mounted device can be calculated according to the specified standby power consumption information, wherein the ratio of the available power to the quasi standby power is the allowed specified standby time of the vehicle-mounted device.
And S30, setting the appointed standby awakening time of the vehicle-mounted equipment according to the allowed appointed standby time.
Understandably, here, the designated standby wake-up time may be a time at which the in-vehicle device wakes up in advance. That is, the specified standby wake-up time is earlier than the actual vehicle usage time. And the difference between the actual vehicle using time and the designated standby awakening time is not greater than the allowed designated standby time. In some examples, the number of times of common vehicle usage by the user per day is n (n is a positive integer), and the allowed standby time period may be divided into n parts, corresponding to the actual vehicle usage time of each time.
And S40, the vehicle-mounted equipment is awakened at the appointed standby awakening time so as to enable the vehicle-mounted equipment to enter an appointed standby state.
Understandably, the vehicle-mounted device can be awakened at the specified standby awakening time, so that the vehicle-mounted device enters the specified standby state. If the vehicle-mounted equipment supports the quasi-standby mode, the vehicle-mounted equipment enters a quasi-standby state; and if the vehicle-mounted equipment does not support the quasi-standby mode, the vehicle-mounted equipment enters a standby state. The vehicle-mounted equipment is awakened in advance, and response waiting time of the vehicle-mounted equipment can be greatly reduced. Here, the in-vehicle device response waiting time refers to a turn-on time that a user experiences after entering the vehicle to perform a power-on operation. By calling up the in-vehicle apparatus in advance, the in-vehicle apparatus response waiting time can be shortened to about 2 seconds.
In steps S10 to S40, the vehicle-mounted battery power information and the specified standby power consumption information of the vehicle-mounted device are obtained, where the available power and the power consumption (or power consumption current) of the vehicle-mounted device during standby are obtained, and the standby time (i.e. the allowed specified standby time) of the vehicle-mounted device can be calculated. And determining the allowed appointed standby time of the vehicle-mounted equipment according to the electric quantity information of the vehicle-mounted storage battery and the appointed standby power consumption information, wherein a proper awakening time can be selected by determining the allowed appointed standby time. And setting the appointed standby awakening time of the vehicle-mounted equipment according to the allowed appointed standby duration, wherein the set appointed standby awakening time can awaken the vehicle-mounted equipment in advance according to the appointed standby awakening time, and meanwhile, the electric quantity of the storage battery is not excessively consumed, so that the normal starting of the automobile is not influenced. And calling the vehicle-mounted equipment at the specified standby awakening time so as to enable the vehicle-mounted equipment to enter a specified standby state, wherein the vehicle-mounted equipment is awakened in advance, so that the response waiting time of the vehicle-mounted equipment felt by a user is greatly reduced, and the user experience is improved.
Optionally, the vehicle-mounted storage battery electric quantity information includes a total electric quantity and a reserved electric quantity ratio of the storage battery, and the specified standby power consumption information includes a specified standby current;
step S20, namely, determining an allowable specified standby time length of the vehicle-mounted device according to the vehicle-mounted storage battery power information and the specified standby power consumption information, includes:
s201, processing the total electric quantity, the reserved electric quantity proportion and the specified standby current of the storage battery through a specified standby time calculation model to generate the allowable specified standby time, wherein the specified standby time calculation model comprises:
A＝B*(α-β)÷U÷C
wherein A is the allowed specified standby time;
b is the total electric quantity of the storage battery;
alpha is the current electric quantity proportion;
beta is the reserved electric quantity proportion;
u is the battery voltage;
c is the specified standby current.
Understandably, the specified standby time calculation model can be set according to actual needs. In some examples, the total battery charge B is related to the battery type selected by the vehicle, and may be in the unit of W · h. The current electric quantity ratio alpha refers to the ratio of the current electric quantity to the total electric quantity of the storage battery. If the battery is in a fully charged state, α =1. The reserved electric quantity proportion beta refers to the proportion of the reserved electric quantity to the total electric quantity of the storage battery, and can be set according to actual needs. In an example, β =0.3. The battery voltage U is typically 12V. The specified standby current C may be an operating current when the in-vehicle apparatus is in a standby state or a quasi-standby state. Since the standby power P = U × C of the in-vehicle device, the above-described specified standby period calculation model may also be expressed as: a = B · (α - β) ÷ P.
As shown in fig. 2, fig. 2 shows the specified standby current and the allowed specified standby time for different vehicle types (supporting the quasi-standby mode). As can be seen from fig. 2, if the specified standby current is large, the allowable specified standby time period in the quasi-standby mode is greatly shortened. As shown in fig. 3, fig. 3 is a diagram showing allowable specified standby periods for different vehicle models (not supporting the standby mode). As can be seen from fig. 3, the fuel vehicle has a small amount of electric power of the battery, so that the allowed standby time in the standby mode is only 30min. The storage battery of the new energy automobile has large electric quantity, but can only support one day.

Understandably, the estimated vehicle-use time refers to the estimated vehicle-use time of the user. The estimated vehicle using time can be obtained according to the vehicle using record of the user. In some examples, a day includes two estimated car hours, eight am and five pm, respectively.
The designated standby wakeup time can be set according to the allowed designated standby duration and the estimated vehicle using time. Here, the designated standby wake-up time may be a power-on time of the in-vehicle device. For example, the estimated vehicle time is eight am, and the designated standby wakeup time is set to be forty-five parts of seven am. The time difference between the estimated vehicle using time and the specified standby wakeup time needs to be smaller than the allowed specified standby time.
Optionally, in step S301, that is, the obtaining of the estimated vehicle-using time of the vehicle includes:
s3011, obtaining a vehicle using record of a user;
and S3012, determining the estimated vehicle using time according to the vehicle using record.
Understandably, the vehicle usage record refers to a vehicle usage record of the user. The user usage record includes the user's usage time. For example, in a user's car record, all the car hours of the user in the past month are recorded, the user's car hours in the morning are between seven and half hours and eighty and fifteen minutes, and the user's car hours in the afternoon are between sixteen hours, forty-five minutes and seventeen-twenty minutes.
The estimated vehicle using time of the user can be set through the vehicle using record. For example, the estimated car time in the morning may be set as a time point in a time period commonly used by the user in the morning; the estimated vehicle time in the afternoon may be set to a point in time in the user's usual hours in the afternoon.
Optionally, in step S3012, determining the estimated vehicle using time according to the vehicle using record includes:
s30121, if the recorded days of the vehicle utilization record are smaller than a day threshold, setting the vehicle utilization time of the specified time period of the previous day as the estimated vehicle utilization time of the specified time period of the current day;
s30122, if the recorded days of the vehicle using record are larger than or equal to the day threshold, calculating expected time of the specified time period according to the vehicle using record, and setting the expected time as estimated vehicle using time of the specified time period.
Understandably, in some cases, the recorded days of the user's car usage are few, less than the threshold number of days, and the user's car usage rules cannot be analyzed. At this time, the time of vehicle usage in the last specified time of day of the user may be set as the estimated time of vehicle usage in the specified time of day. The day threshold may be set according to actual needs, such as a week or a month.
If the recorded days of the vehicle using record are larger than or equal to the threshold of the days, the vehicle using rule of the user is analyzed according to the vehicle using record, and the expected time of the user in the specified time period is further determined. The desired time may be set to the estimated vehicle time for the specified time period. Here, the desired time may be an average of all the usage times for a specified period of time in the usage log. In particular, the expected time may only count the vehicle usage records of the weekdays.
Optionally, step S302, namely, the setting the designated standby wakeup time according to the allowed designated standby duration and the estimated vehicle use time includes:
s3022, processing the allowed specified standby duration and the estimated vehicle using time through a specified standby wake-up time model, and generating the specified standby wake-up time, wherein the specified standby wake-up time model comprises:
T wi ＝T i -A*γ i
wherein, T wi Assigning a standby wakeup time for the ith day;
T i estimating the vehicle using time for the ith day;
a is the allowed specified standby time;
γ i and distributing coefficients for the ith wake-up time of each day.
Understandably, the specified standby wakeup time model can be set according to actual needs. Wherein, γ i And distributing coefficients to the ith wake-up time of each day, wherein the values of the coefficients are less than 1. If there are n wake-up time allocation coefficients, the sum of all wake-up time allocation coefficients may be less than or equal to 1.
Optionally, before step S3022, that is, before the processing the allowed specified standby duration and the estimated vehicle usage time through the specified standby wake-up time model and generating the specified standby wake-up time, the method further includes:
s3021, calculating the wake-up time allocation coefficient according to a wake-up time allocation coefficient model, where the wake-up time allocation coefficient model includes:
wherein, delta j A time difference for the jth specified period; j is a variable belonging to a positive integer, the value of j is 1, 2, … …, n, and n is the number of the designated time intervals;

Understandably, the time difference delta if the recorded days of the vehicle is less than the days threshold i May be the maximum time span of the ith designated time period (the latest time spent minus the earliest time spent in the designated time period). The recorded days are greater than or equal to the threshold of days, and the time difference is delta i May be the standard deviation sigma for the ith specified period (where the user's usage time is considered to be normally distributed).
