The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

It should be noted that, in the prior art, when the vehicle is parked for a long time or in a severe cold environment, the engine in the vehicle is difficult to start, and when the vehicle is parked for a long time, the electric components in the vehicle need to keep working, which may cause the battery in the vehicle to run out of power, resulting in the vehicle not being started. In view of this, the present application proposes a vehicle control method, a vehicle control device, a vehicle, and a storage medium, by which normal start of the vehicle can be ensured while reducing power consumption of the vehicle.

For example, as shown in fig. 1, when the vehicle 100 is parked for a long time or in a severe cold environment, if it is determined that the vehicle is in a target parking scene, the vehicle is awakened and a first temperature of a storage battery in the vehicle is collected, if the first temperature is greater than a first preset temperature threshold, an awakening time interval is determined based on the first temperature, and the vehicle is controlled to sleep.

Specifically, if the temperature of the target parking scene is less than or equal to a second preset temperature threshold, determining a wake-up time interval based on the first temperature and the vehicle exterior temperature of the vehicle; if the temperature of the target parking scene is greater than or equal to a second preset temperature threshold value and the parking time of the vehicle is greater than a preset time threshold value, acquiring the current electric quantity of the storage battery; a wake-up time interval is determined based on the current power and the first temperature.

In one example, if the temperature of the target parking scene is less than or equal to a second preset temperature threshold, a target temperature difference is obtained based on the first temperature and the off-board temperature; a wake-up time interval is determined based on the target temperature difference. Note that the wake-up time interval is positively correlated with the absolute value of the target temperature difference. That is, the larger the target temperature difference between the first temperature and the outside temperature means the longer the allowable discharge period of the battery.

Alternatively, the calibration electrical quantity may be dynamically set, i.e. the calibration electrical quantity may be determined from the ambient temperature; or the calibration power can be fixed. The setting mode of the calibration electric quantity is determined according to the actual situation, and is not particularly limited herein.

It should be noted that, the vehicle is configured with an engine, and the parameter of the battery indicates that the battery is at risk of power shortage, and a start signal is sent to the engine of the vehicle, so that the battery is charged after the engine is started successfully. When the engine starts, the generator rotates and generates electric energy by using mechanical energy of the engine, and the electric energy is transmitted to the storage battery for charging. Specifically, after the engine is started, voltage is induced in a magnetic field by rotating a coil inside the generator, so that electric energy is generated, and the generated electric energy is converted into direct current and is transmitted to the storage battery to finish charging the storage battery.

Alternatively, the first preset period may be 10 days, 15 days, 30 days, etc., without being particularly limited herein.

Alternatively, the first preset time period may be 100 hours, 150 hours, or the like, which is not particularly limited herein.

Alternatively, the first preset threshold may be 3 times, 5 times, etc., which is not particularly limited herein.

For example, after sending a start signal to the engine of the vehicle, whether the engine is started up or not may be detected, and if the engine is detected to be started up, the failure number of continuous start-up failures of the engine may be obtained. And detecting whether the failure times are greater than a second preset threshold value, and if the failure times are greater than the second preset threshold value, outputting second prompt information which is used for prompting a user to manually start the engine.

For example, the method shown in FIG. 2 may be performed by an overall vehicle controller or chip of a vehicle.

The vehicle is provided with an engine.

Illustratively, as shown in FIG. 2, the method 200 includes the following processes:

s210, if the vehicle is in the target parking scene, waking up the vehicle and collecting the first temperature of the storage battery in the vehicle.

Alternatively, the target parking scene may be a long-time parking scene of the vehicle, or may be a parking scene of the vehicle in a severe cold environment. The target parking scene may be determined according to actual situations, and is not particularly limited herein.

Illustratively, an ambient temperature of an environment in which the vehicle is located is obtained; if the ambient temperature is less than or equal to a third preset temperature threshold, determining that the vehicle is in a target parking scene; or acquiring flameout time of the vehicle; if the flameout time length is longer than the preset time length, determining that the vehicle is in a target parking scene; the environment temperature is a temperature obtained through an on-board terminal of the vehicle.

Further, it is determined that the vehicle is in a target parking scenario, the vehicle is awakened, and a first temperature of a battery in the vehicle is collected. Specifically, in the event that the vehicle is determined to be in a target parking scenario, a first temperature of the battery is monitored by a battery management system (EBS).

According to the scheme, whether the vehicle is in a target parking scene with the power shortage risk can be determined through the environmental temperature of the environment where the vehicle is or the flameout duration of flameout of the vehicle; when the vehicle is in the target parking scene, the vehicle can be awakened to collect parameters of the storage battery; when the vehicle is detected to be in the target parking scene, the vehicle is awakened to collect data, and the power consumption of the vehicle is reduced.

S220, if the first temperature is greater than a first preset temperature threshold, determining a wake-up time interval based on the first temperature, and controlling the vehicle to sleep.

For example, after determining the first temperature of the battery, detecting whether the first temperature is greater than a first preset temperature threshold, and if the first temperature is less than or equal to the first preset temperature threshold, waking up the vehicle to collect parameters of the battery; if the first temperature is greater than a first preset temperature threshold, determining a wake-up time interval based on the first temperature, and controlling the vehicle to sleep. Specifically, if the first temperature is greater than a first preset temperature threshold, a wake-up time interval is determined based on the first temperature, and vehicle dormancy is controlled by a vehicle body area Controller (CEM).

Alternatively, the first preset temperature threshold may be set at-19 ℃, -20 ℃ and so on, without limitation.

For example, it is detected whether the temperature of the target parking scene is less than or equal to a second preset temperature threshold, and if the temperature of the target parking scene is less than or equal to the second preset temperature threshold, a wake-up time interval is determined based on the first temperature and the off-board temperature of the vehicle.

Alternatively, the second preset temperature threshold may be set at-19 ℃, -20 ℃ and so on, without limitation.

For example, it is detected whether the temperature of the target parking scene is less than or equal to-19 ℃, and if the temperature of the target parking scene is less than or equal to-19 ℃, the wake-up time interval is determined from the absolute value of the temperature difference between the first temperature and the off-board temperature of the vehicle.

Alternatively, the absolute value of the temperature difference may be set as the wake-up time interval, or the temperature difference may be weighted to determine the wake-up time interval. The wake-up time interval may be determined according to practical situations, and is not specifically limited herein.

The method includes the steps that if the temperature of a target parking scene is greater than a second preset temperature threshold, the parking duration of a vehicle is obtained, whether the parking duration of the vehicle is greater than the preset duration threshold is detected, and if the parking duration of the vehicle is greater than the preset duration threshold, the current electric quantity of a storage battery is obtained; a wake-up time interval is determined based on the current power and the first temperature.

For example, detecting whether the temperature of the target parking scene is less than or equal to-19 ℃, if the temperature of the target parking scene is greater than-19 ℃, acquiring the parking time of the vehicle, detecting whether the parking time of the vehicle is greater than 1500 hours, and if the parking time of the vehicle is greater than 1500 hours, acquiring the current electric quantity of the storage battery; a wake-up time interval is determined based on the current power and the first temperature. Specifically, a difference between the current electric quantity and the calibrated electric quantity is determined, and a wake-up time interval is determined according to a product between the difference and the first temperature.

Alternatively, the product between the difference and the first temperature may be determined as the wake-up time interval, or the product between the difference and the first temperature may be weighted to determine the wake-up time interval. The wake-up time interval may be determined according to practical situations, and is not specifically limited herein.

Alternatively, the preset duration threshold may be set to 1500 hours, 1600 hours, etc., without limitation.

According to the scheme, if the temperature of the target parking scene where the vehicle is located is smaller than or equal to the second preset temperature threshold value, namely the target parking scene is a low-temperature parking scene; the wake-up time interval may be determined based on the first temperature and the off-board temperature; it can be understood that when the target parking scene is a low-temperature scene, the discharging speed of the storage battery can be determined through the first temperature and the outside temperature of the storage battery; based on the discharge speed, determining a wake-up time interval; or if the target parking scene where the vehicle is located is that the temperature is greater than or equal to a second preset temperature threshold and the parking time length of the vehicle is greater than a preset time length threshold, that is, the target parking scene is that the vehicle is parked for a long time, the wake-up time interval can be determined based on the current electric quantity of the storage battery and the first temperature of the storage battery; in the scheme, based on different target parking scenes, different wake-up time intervals can be determined, so that the accuracy of the wake-up time intervals is improved.

For example, if the temperature of the target parking scene is less than or equal to the second preset temperature threshold, the first temperature is-10 ℃, the off-vehicle temperature is-15 ℃, the target temperature difference is 5 ℃, and the wake-up time interval can be determined to be 5 hours; or determining 5a as a wake-up time interval. Of course, if the first temperature is-15 ℃, the outside temperature is-10 ℃, the target temperature difference can be determined to be 5 ℃, and the wake-up time interval can be determined to be 5 hours; or determining 5a as a wake-up time interval

Optionally, a is a preset coefficient, and a may be set according to actual requirements, or may be a calibrated fixed value, which is not specifically limited herein.

According to the scheme, if the temperature of the target parking scene where the vehicle is located is smaller than or equal to the second preset temperature threshold value, namely the target parking scene is a low-temperature parking scene; obtaining a target temperature difference value based on the first temperature of the storage battery and the temperature outside the vehicle; determining a wake-up time interval through the temperature difference value; it can be understood that the larger the target temperature difference value is, the larger the discharge duration of the storage battery is, the longer the acquired time interval can be, namely, the longer the wake-up time interval is; by the scheme, the accurate wake-up time interval can be determined, so that the power consumption of the vehicle is reduced.

It should be noted that the calibration electric quantity may be dynamically set, that is, the calibration electric quantity may be determined according to the ambient temperature; or the calibration power can be fixed. The setting mode of the calibration electric quantity is determined according to the actual situation, and is not particularly limited herein.

For example, if the temperature of the target parking scene is greater than the second preset temperature threshold and the parking time of the vehicle is greater than the preset time threshold, the current electric quantity of the storage battery is obtained as P2, the calibrated electric quantity is obtained as P3, and the target electric quantity difference value P2-P3 is a positive value based on the current electric quantity P2 and the calibrated electric quantity P3 because the current electric quantity P2 is greater than the calibrated electric quantity P3. If the first temperature is T7, the wake-up time interval may be (P2-P3) T7; or the wake-up time interval may be d (P2-P3) T7.

Optionally, d is a preset coefficient, and d may be preset as a fixed coefficient, or may be determined according to an environmental change, which is not specifically limited herein.

According to the scheme, if the target parking scene where the vehicle is located is the temperature greater than or equal to the second preset temperature threshold and the parking time length of the vehicle is greater than the preset time length threshold, namely the target parking scene is the long-term parking scene of the vehicle, the discharging time length of the storage battery can be determined according to the difference value between the current electric quantity value and the calibrated electric quantity of the vehicle and the first temperature value of the storage battery; for example, the larger the target electric quantity difference value is, the longer the discharge duration is; the higher the first temperature, the longer the discharge duration; by the scheme, the accurate wake-up time interval can be determined, so that the power consumption of the vehicle is reduced.

S230, after the wake-up time interval is reached, the vehicle is waken to collect parameters of the storage battery.

Illustratively, a target temperature difference is obtained based on the first temperature and the outside temperature, and a wake-up time interval is determined based on the target temperature difference; the awakening time interval is the ith awakening time interval; waking up the vehicle to collect a second temperature of the storage battery; if the temperature of the target parking scene is smaller than or equal to a second preset temperature threshold value, determining an i+1st wake-up time interval based on a temperature difference value between the first temperature and the second temperature and the target temperature difference value; the (i+1) th wake-up time interval is positively correlated with the temperature difference value and the target temperature difference value; i is a positive integer.

For example, a target temperature difference value T5-T2 (T2-T5) is obtained based on the first temperature T5 and the outside temperature T2, and an ith wake-up time interval a (T2-T5) is determined based on the target temperature difference value; waking up the vehicle to collect a second temperature T6 of the storage battery; if the temperature of the target parking scene is less than or equal to the second preset temperature threshold, determining an i+1st wake-up time interval b (T2-T5) (T6-T5) based on a temperature difference T6 between the first temperature T5 and the second temperature and the target temperature difference (T2-T5).

Optionally, a and b are both coefficients, and the setting manner of b may refer to the setting manner of a in the foregoing disclosed embodiment, which is not described herein.

According to the scheme, the wake-up time interval can be determined based on the current temperatures of the storage battery at different moments; that is, the wake-up time interval in the above scheme may be a time interval dynamically changed in real time, so as to improve accuracy of the wake-up time interval and reduce power consumption of the vehicle.

It is understood that waking up the parameters of the vehicle to collect the battery may further include waking up the vehicle to collect a current power of the battery, and determining whether the battery is at risk of power shortage according to the current power.

And S240, if the parameters of the storage battery indicate that the storage battery has a power shortage risk, sending a starting signal to an engine of the vehicle so as to charge the storage battery after the engine is started successfully.

For example, if the current temperature of the storage battery is less than the fourth temperature threshold, obtaining the current electric quantity of the storage battery; if the current electric quantity is greater than or equal to a preset electric quantity threshold value, determining that the storage battery does not have the power shortage risk, and waking up the vehicle at intervals to collect the current electric quantity of the storage battery; and if the current electric quantity is smaller than the preset electric quantity threshold value, determining that the storage battery has the power shortage risk.

For example, if the current temperature of the storage battery is less than-19 ℃, acquiring the current electric quantity of the storage battery; if the current electric quantity is greater than or equal to P0, determining that the storage battery does not have the power shortage risk, and collecting the current electric quantity of the storage battery by waking up the vehicle at intervals; if the current electric quantity is smaller than P0, determining that the storage battery has a power shortage risk.

Optionally, the preset power threshold may be a calibrated power, may be set to a fixed value, or may be determined according to the first temperature of the storage battery. The preset power threshold may be determined according to actual situations, and is not specifically limited herein.

Alternatively, the fourth temperature threshold may be set at-19 ℃, -20 ℃ and so on, without specific limitation herein.

According to the scheme, if the current temperature of the storage battery is smaller than the fourth preset temperature threshold value, the current electric quantity of the storage battery is obtained; that is, it can be understood that when the current temperature of the battery is lower than the fourth temperature threshold, battery power shortage is likely to occur; under the condition that the storage battery is easy to be deficient in power, the current electric quantity of the storage battery is collected, and compared with the current electric quantity of the storage battery collected in real time, the power consumption of a vehicle can be reduced to a certain extent.

For example, after sending a start signal to an engine of a vehicle, the number of success times of starting the engine in a first preset period of time may be obtained, and whether the number of success times is greater than a first preset threshold value may be detected, and if the number of success times is less than or equal to the first preset threshold value, the step of detecting whether the vehicle is in a flameout state and the subsequent steps may be continuously performed; if the success times are larger than a first preset threshold value, a target time interval of successful starting is obtained based on the time interval of successful starting of two adjacent times. Detecting whether the target time interval is smaller than a first preset duration, if the target time interval is larger than or equal to the first preset duration, continuing to execute the step of detecting whether the vehicle is in a flameout state or not and the subsequent steps; if the target time interval is smaller than the first preset time length, outputting first prompt information, wherein the first prompt information is used for indicating that the storage battery has faults.

Alternatively, the first preset period may be 10 days, 15 days, 30 days, etc., and is not particularly limited herein.

Alternatively, the first preset time period may be 20 hours, 50 hours, 100 hours, 150 hours, etc., which is not particularly limited herein.

For example, after a start signal is sent to an engine of a vehicle, the successful number of times of starting the engine successfully within 100 hours can be obtained, whether the successful number of times is more than 3 times is detected, and if the successful number of times is less than or equal to 3 times, the step of detecting whether the vehicle is in a flameout state and the subsequent steps are continuously executed; if the success times are more than 3 times, obtaining a target time interval of successful starting based on the time interval of successful starting of the two adjacent times.

Specifically, the success times are 4 times, the time interval of the success of the adjacent two starting times in the 4 starting successes comprises 35 hours, 30 hours and 25 hours, and the average value of the time intervals is taken as the target time interval of the starting successes, wherein the average value of the time intervals is 30 hours; or the latest one time interval 25 is taken as the target time interval for successful start-up. Further, whether the target time interval is smaller than 50 hours or not is detected, the target time interval is smaller than 50 hours, first prompt information is output, and the first prompt information is used for indicating that the storage battery has faults so as to overhaul the storage battery, and therefore normal starting of an engine is guaranteed.

According to the scheme, if the successful times of starting success in the first preset time period is larger than the first preset threshold value, a target time interval of starting success is determined, and if the target time interval is smaller than the first preset time length, first prompt information is output to indicate that the storage battery has faults; the first prompt information is determined under the condition that the starting times and the target time interval in the preset time period meet the preset conditions, namely, whether the storage battery fails or not is determined through the starting times and the target time interval in the preset time period, so that a user can be timely prompted to maintain the storage battery as soon as possible under the condition that the storage battery fails is determined, and further normal starting of an engine is ensured.

The first prompt information may be prompted by voice through the electronic device. For example, the first prompt message may be "your good, the battery is faulty, please overhaul the battery as soon as possible. Or the first prompt message may be prompted by email. The output manner of the first prompt information may be determined according to the actual situation, which is not specifically limited herein.

For example, after sending a start signal to the engine of the vehicle, whether the engine is started up or not may be detected, if the engine is detected to be started up, the failure number of continuous start-up failures of the engine is obtained, and whether the failure number is greater than a second preset threshold is detected; if the failure times are smaller than or equal to a second preset threshold value, continuing to execute the step of detecting whether the vehicle is in a flameout state or not and the subsequent steps; if the failure times are greater than a second preset threshold, outputting second prompt information, wherein the second prompt information is used for prompting a user to manually start the engine.

For example, if an engine start failure is detected, acquiring the failure times of continuous start failure of the engine, and detecting whether the failure times are more than 3 times; if the failure times are smaller than or equal to a second preset threshold value, continuing to execute the step of acquiring the failure times of continuous starting failure of the engine and the subsequent steps; if the failure times are more than 3 times, outputting a second prompt message to prompt the user to manually start the engine.

According to the scheme, the failure times of continuous starting failure of the engine are obtained, and if the failure times are larger than a second preset threshold value, second prompt information is output to prompt a user to manually start the engine; because the number of continuous start failures is larger than the second preset threshold value, the automatic start abnormality of the engine is represented, and the user is prompted to manually start the engine, so that the damage of the engine and electric components in the vehicle caused by repeated automatic start of the engine is avoided under the condition of abnormal automatic start of the engine, and the service life of the electric components in the vehicle is prolonged.

The second prompt information may be prompted by voice through the electronic device. For example, the second prompt message may be "your good, the engine fails to start multiple times, please start the engine manually, so that the battery is charged after the engine starts successfully. Or the second prompt message may be prompted by email. The output mode of the second prompt information may be determined according to the actual situation, which is not specifically limited herein.

According to the technical scheme, the wake-up time interval is determined based on the first temperature, and the vehicle is controlled to sleep; after reaching the wake-up time interval, waking up the vehicle to collect parameters of the storage battery; if the parameters of the storage battery indicate that the storage battery has the power shortage risk, starting a starting signal to an engine of the vehicle so as to charge the storage battery after the engine is successfully started; compared with the prior art, the method has the advantages that the vehicle is in the wake-up state in real time to collect the parameters of the storage battery, or the vehicle wakes up the parameters of the storage battery based on a preset period which is preset; according to the scheme, the wake-up time interval of the vehicle can be dynamically determined based on the first temperature of the storage battery, so that the accuracy of the wake-up time of the vehicle is improved to a certain extent; the accuracy of the vehicle wake-up time is improved, so that the power consumption of the vehicle can be reduced; thus, the normal starting of the vehicle is ensured under the condition of reducing the power consumption of the vehicle.
