The method disclosed by the disclosure is applied to a vehicle controller, wherein the vehicle controller can be arranged in a central control System of the vehicle and can also be arranged in a control component of an Engine Management System (EMS) as a new controller of the EMS.

FIG. 1 illustrates a flowchart of a vehicle charge control method according to an exemplary embodiment of the present disclosure.

In step S101, the running state information of the vehicle is acquired.

The driving state information of the vehicle may be driving data generated during the driving process of the vehicle, or an average driving state of the vehicle in a certain time period, which represents a driving habit or a vehicle using state of a user in a set time period, where the set time period may be set according to an actual requirement, for example, a recent week time. For example, the driving state information may include a usage time interval of the vehicle or a navigation route of the vehicle.

In step S102, the engine control system EMS is controlled to adjust a State Of Charge SOC (State Of Charge) balance point Of a battery Of the vehicle according to the running State information Of the vehicle.

The engine control system EMS can be used for adjusting the SOC balance point of the vehicle storage battery, and in addition, can be used for controlling a vehicle generator to charge the vehicle storage battery. The vehicle storage battery can be a storage battery for starting the vehicle and is mainly used for supplying power for starting a vehicle engine and other electrical appliances in the vehicle. And acquiring the vehicle using state of the user according to the driving state information obtained in the step, so that the EMS can adjust the SOC balance point of the vehicle storage battery according to the vehicle using state of the user.

In step S103, the EMS is controlled to charge the vehicle battery according to the SOC balance point.

The SOC is used as the state of charge of the vehicle battery and represents the residual capacity of the vehicle battery, and the SOC balance point represents the control parameter of the SOC. The EMS can charge the vehicle storage battery according to the SOC balance point by controlling the vehicle storage battery, so that the residual electric quantity of the vehicle storage battery is kept at the electric quantity value determined by the SOC balance point. Wherein the EMS may be controlled to start the charging process according to the SOC balance point after the vehicle is started.

According to the method, the SOC balance point of the vehicle storage battery is adjusted according to the running state information of the vehicle and charging is carried out, so that the SOC balance point of the vehicle storage battery keeps a correlation with the vehicle using state of a user, and the fuel economy of the vehicle and the safety of the vehicle storage battery are improved.

In some embodiments, the driving state information of the vehicle may include a usage time interval of the vehicle. The use frequency of the vehicle in a preset time period can be self-learned according to a timing chip in a vehicle transmitter so as to determine the use time interval of the vehicle, namely the average use frequency of the vehicle in the near future of a user. Then, the EMS may be controlled to adjust different SOC balance points according to the length of the service time interval of the vehicle, and the specific SOC balance point adjustment method may be divided into the following three cases:

in a first case, in response to the usage time interval of the vehicle being less than a first time threshold, controlling the EMS to adjust the SOC balance point of the vehicle battery to a first balance point, the first balance point being lower than a factory default balance point of the vehicle battery.

Wherein the first time threshold may be set according to actual requirements, for example, 24 hours (time of day). Under the condition that the service time interval is less than the first time threshold value, the present user's of sign frequency of using the car is frequently used, can with the SOC balance point of vehicle storage battery is followed default balance point of leaving the factory reduces to first balance point, for example sets up the residual capacity of vehicle storage battery at 60% to reduce vehicle in-process vehicle storage battery internal storage capacity of going, make the generator frequently not generate electricity in order to the unnecessary electric energy of vehicle storage battery storage, can reduce in the vehicle use because excessive generate heat and the potential safety hazard that high SOC balance point caused, further promote the fuel economy of vehicle. In addition, because the current vehicle is in the frequent use state, can not lead to the unable start-up of vehicle engine because of long-term continuous discharge of vehicle storage battery is caused to park for a long time.

In a second case, in response to a usage time interval of the vehicle being greater than or equal to the first time threshold and less than a second time threshold, controlling an EMS to adjust a SOC balance point of the vehicle battery to a second balance point, the second balance point being higher than the first balance point and lower than a factory default balance point of the vehicle battery.

Likewise, the second time threshold may be set according to actual requirements, for example 168 hours (one week time). Under the condition that the service time interval is between the first time threshold and the second time threshold, the vehicle using frequency of the current user is represented as normal use, namely compared with a frequently-used scene, the service time interval of the vehicle is relatively longer, the SOC balance point of the vehicle battery can be properly adjusted upwards, for example, the SOC balance point is adjusted from 60% (the first balance point) to 80% (the second balance point), under the condition that the fuel economy of the vehicle is ensured, the possibility that the battery is insufficient due to the fact that the vehicle is parked for a long time is reduced, and the vehicle battery is ensured to have enough electric quantity to support the normal starting of the vehicle.

In a third case, in response to the usage time interval of the vehicle being greater than or equal to the second time threshold, controlling an EMS to adjust the SOC balance point of the vehicle battery to a factory default balance point of the vehicle battery.

After the service time interval exceeds the second time threshold, the characteristic that the current user does not frequently use the vehicle is achieved, the EMS can be controlled to adjust the SOC balance point of the vehicle storage battery to the factory default balance point of the vehicle storage battery, such as 90%, the situation that the vehicle is in a state of continuous discharging to a power shortage state due to long-time parking is avoided, and the user can be ensured to normally start the vehicle when the vehicle is used next time.

According to the method, different SOC balance points are determined according to the length of the service time interval of the vehicle, so that the SOC balance points of the vehicle storage battery keep a correlation with the vehicle service frequency of a user, and the fuel economy of the vehicle and the safety of the vehicle storage battery are improved.

After determining the SOC balance point of the vehicle battery according to the above steps and the usage time interval of the vehicle, further, the present disclosure further provides two preferred embodiments for step 103 to improve the health of the vehicle battery.

The first embodiment is shown in fig. 2, and specifically includes steps S103a to S103c.

In step S103a, in response to that the electric quantity Of the vehicle battery does not reach a preset State during a first number Of driving cycles Of the vehicle, obtaining a State Of Health (SOH) Of the vehicle battery.

The preset state can represent that the electric quantity of the vehicle storage battery is in a full-charge state or is charged to the electric quantity to reach a set proportion, for example, a 90% state, the vehicle storage battery is continuously charged for multiple times without reaching the full-charge state, and for the common vehicle storage battery, if the storage battery formed by a lead-acid storage battery is easy to generate a battery vulcanization phenomenon, the capacity of the vehicle storage battery is reduced, and the service life of the vehicle storage battery is shortened. Thus, in an alternative embodiment, the SOH of the vehicle battery is obtained if the vehicle battery is not in the predetermined state during a first number of driving cycles (e.g. 5 times). The SOH of the vehicle storage battery can be acquired through a battery sensor of the vehicle, and the battery sensor is connected with the EMS through a serial access network (LIN bus) and used for monitoring the SOC state, the health degree and the charging efficiency of the vehicle storage battery.

In step S103b, in response to the vehicle being driven in a second number of cycles, the electric quantity of the vehicle battery not reaching a preset state, the EMS is controlled to charge the vehicle battery to a full state, wherein the second number is greater than the first number.

Wherein, first predetermined condition token the SOH of vehicle storage battery is good, can be in the vehicle is again through the second number drive cycle process (for example 10) after, and battery power still has not reached under the condition of default condition, control EMS is right the vehicle storage battery carries out full charge, guarantees that the vehicle storage battery at least every and all carries out once full charge after first figure adds the second number drive cycle, maintains the SOH of vehicle storage battery.

In step S103c, if the SOH of the vehicle battery does not satisfy the first preset condition, controlling an EMS to charge the vehicle battery to a full state.

The vehicle battery pack is characterized in that the SOH of the vehicle battery is poor when the first condition is not met, and the full-electricity charging can be carried out on the electrical frequency, so that the capacity reduction caused by long-term undercharge of the battery can be avoided.

In the above steps, the full charge may be a multiple charging process to further ensure the SOH of the vehicle battery.

In the embodiment, the vehicle storage battery is fully charged through the health state of the electric quantity of the vehicle storage battery, so that the health degree of the vehicle storage battery is ensured, and the service life of the vehicle storage battery is prolonged.

The second embodiment is shown in fig. 3, and specifically includes steps S103A to S103D.

In step S103A, in response to the vehicle entering the parking state, according to the SOC state of the vehicle storage battery determines the maximum electric quantity consumption time of the vehicle, the maximum electric quantity consumption time represents the time required by the electric quantity consumption of the vehicle storage battery to the power shortage state, the remaining electric quantity of the current storage battery of the power shortage state represents that the remaining electric quantity is less than the SOC balance point of the automobile storage battery, the power shortage state easily results in that the electric quantity of the storage battery can not provide enough electric energy for the engine starting.

Under the condition that a vehicle is parked, the residual electric quantity in the current vehicle storage battery can be determined according to the SOC state of the vehicle storage battery, and the time interval required by the electric quantity of the vehicle storage battery to be consumed in a power shortage state, namely the maximum electric quantity consumption time, can be determined according to the residual electric quantity.

In step S103B, a first prompt message is sent, where the first prompt message is used to prompt the user of the maximum power consumption time.

Can pass through entertainment system host controller HU of vehicle plays pronunciation or characters suggestion information, suggestion user the maximum electric quantity consumption time, wherein HU passes through controller area network (CAN line) with the EMS and is connected.

In step S103C, in response to that the parking duration and the maximum consumption time of the vehicle do not satisfy the setting condition, sending a second prompt message, where the second prompt message is used to prompt a user to select whether to charge the vehicle battery.

The unsatisfied settlement condition, the stop time that the representation vehicle has closed to the time that the vehicle storage battery is about to take place to starve electricity, CAN send the second prompt message in order to indicate the user, exemplarily, CAN send the bullet window information to user terminal's relevant APP through the telematics system T-BOX of vehicle, indicate the user that the vehicle storage battery is about to starve electricity, inquire whether the user is to the vehicle storage battery charges, wherein T-BOX and EMS are connected through controller area network (CAN line).

In step S103D, when a user charging instruction is received, the EMS is controlled to charge the vehicle battery according to the SOC balance point.

If the user selects to start charging, the EMS can be remotely controlled to charge the vehicle storage battery, the service time interval of the vehicle is updated, and if the service time interval is close to the maximum electric quantity consumption time again, the second prompt message is sent to the user again.

Furthermore, in the event that a user charge command is not received, a starved state of the vehicle battery may be obtained, in one example, the battery sensor may be configured to determine a relationship between a vehicle battery remaining capacity and a vehicle battery SOC balance point to determine the starved state, and in response to the vehicle battery starving, a charging efficiency of the vehicle battery may be obtained and the EMS may be controlled to charge the vehicle battery.

Specifically, the charging efficiency of vehicle storage battery is greater than or equal to and predetermines under the condition of efficiency threshold value, and the charging efficiency of the current vehicle storage battery of sign is higher, can pass through EMS control the vehicle storage battery charges to full state many times with first number of times of charging, and the charging efficiency of vehicle storage battery is less than predetermine under the condition of efficiency threshold value, the charging efficiency of the current vehicle storage battery of sign is lower, can pass through EMS control the vehicle storage battery charges to full state many times with the second number of times of charging, wherein, the second number of times of charging is greater than first number of times of charging, and charging efficiency is higher promptly, and full number of times of charging is less to restore the battery that takes place to lack the electricity, resume vehicle battery's SOH.

In the embodiment, promote the user in time to charge to the vehicle storage battery through the tip information, avoid the vehicle because of long-time parking the deficient electricity that causes. And under the condition that the vehicle storage battery is short of electricity, the vehicle storage battery is fully charged according to a preset rule, the health degree of the vehicle storage battery is improved, and the service life of the vehicle storage battery is prolonged.

In other embodiments, the driving state information of the vehicle includes a navigation route of the vehicle, and the EMS may be controlled to determine different SOC balance points according to a planned distance of the navigation route, which includes the following specific steps:

firstly, according to the current navigation route of the vehicle, the planning distance between the starting position and the ending position of the vehicle is determined.

Further, in response to the planned distance being greater than a first distance threshold, characterizing that the vehicle is about to travel for a long distance, and controlling the SOC of the vehicle battery to a third equilibrium point under the condition that the distance to be traveled by the vehicle is greater than a second distance threshold, the third equilibrium point being lower than a factory default equilibrium point of the vehicle battery; under the condition that the distance of waiting to travel of vehicle is less than or equal to second distance threshold, through EMS control vehicle storage battery's SOC equilibrium point to fourth equilibrium point, the fourth equilibrium point is higher than the third equilibrium point and is less than the default equilibrium point of leaving the factory of vehicle storage battery.

Specifically, as shown in fig. 4, the second distance threshold value represents the vehicle is about to reach the terminal position, and when the distance to be traveled is greater than the second distance threshold value, the SOC balance point of the vehicle battery can be reduced from the factory default balance point to the third balance point through the EMS, so that the amount of power stored in the vehicle battery during the vehicle traveling process is reduced, the generator does not frequently generate power to store redundant electric energy to the vehicle battery, and the fuel economy of the vehicle is further improved.

Wherein 10% of the total length from the planned distance may be set as the second distance threshold. And when the distance to be traveled is smaller than the second distance threshold value, representing that the user is about to reach a terminal point, and properly adjusting the SOC balance point of the EMS battery to a fourth balance point. Because the user is in the in-process of long-distance driving, the terminal position is usually in strange environment, for further avoiding the emergence of the short-circuit condition, can reduce the possibility that makes the battery short-circuit because of the vehicle parks for a long time through the SOC balance point that increases properly under the condition of guaranteeing vehicle fuel economy, ensures that the vehicle storage battery has sufficient electric quantity to support the normal start of vehicle, avoids the user because the vehicle can't start causing the puzzlement in the process of returning journey.

Preferably, an average travel distance between common positions of the user determined by the historical navigation route of the vehicle may be used as the first distance threshold, where the common positions are determined according to a start position and an end position set by the user within a preset time period.

Specifically, the common position and the average travel distance of the user, such as the commuting distance and the daily shopping distance of the user, can be learned by self according to the recent information of the user, such as the recent round trip driving condition and the destination setting, and when the planned distance exceeds the average travel distance of the user, the fact that the user is going to travel for a long distance is represented, and the end point position does not belong to the common position of the user, the SOC balance point of the vehicle battery can be adjusted through the EMS by adopting the method.

Further, an extra-long distance running distance can be set as a third distance threshold, if the planned distance is greater than or equal to the third distance threshold, it is represented that a user is about to run for extra-long distance, such as continuous trans-provincial running, and the EMS can be controlled to adjust the SOC balance point of the vehicle battery to the third balance point so as to improve the fuel economy of the vehicle under the condition that the distance to be run of the vehicle is greater than the first distance threshold; and under the condition that the distance to be traveled of the vehicle is less than or equal to the first distance threshold value, controlling an EMS (energy management system) to adjust an SOC (system on chip) balance point of the vehicle storage battery to a factory default balance point of the vehicle storage battery, so that the vehicle storage battery stores electric quantity as much as possible, and the condition that the vehicle is parked for a long time in a strange environment and the battery is short of electricity is avoided.

According to the method, different SOC balance points are determined according to the planning distance of the vehicle navigation route, so that the SOC balance points of the vehicle storage battery and the travel planning progress of a user keep a correlation, and the fuel economy of the vehicle and the safety of the vehicle storage battery are improved.
