Any solution using a hybrid vehicle power mode management method, device, electronic device and storage medium provided by the embodiments of the present application is within the protection scope of the present application.

[0053] It is worth noting that a plug-in hybrid electric vehicle (PHEV) is a new energy vehicle between pure electric vehicles and fuel vehicles. It has the engine, transmission, drive system, oil circuit and fuel tank of a traditional vehicle, as well as the battery, motor and control circuit of a pure electric vehicle. It combines the advantages of pure electric vehicles (EV) and hybrid electric vehicles (HEV), and can achieve pure electric and zero-emission driving, as well as increase the vehicle's range through hybrid mode.

[0054] At present, in order to prevent users from being unable to charge plug-in hybrid vehicles externally in time, the battery's state of charge (SOC) balance value is generally set high. When the remaining capacity percentage of the battery is lower than the SOC balance value, the power mode of the plug-in hybrid vehicle will switch from pure electric mode to hybrid mode, consuming fuel to replenish the battery to ensure power demand; however, this power mode causes the power below the SOC balance value to be unusable, resulting in a waste of power; therefore, how to manage the power mode of plug-in hybrid vehicles to improve the utilization rate of battery power has become an urgent problem to be solved.

[0055] Based on this, the present application proposes a management method, device, electronic device and storage medium for a hybrid vehicle power mode, the management method comprising: obtaining result information of whether a target hybrid vehicle is charged at a destination after driving from a current position to a destination, determining a target balance value of a charge state of a battery of the target hybrid vehicle according to the result information, and determining a remaining power corresponding to the target balance value as a target remaining power; wherein the target balance value is a ratio of the remaining power corresponding to the remaining power of the battery of the target hybrid vehicle when charging and the remaining power when discharging reach a balance to the total power of the battery; obtaining a current remaining power of the battery of the target hybrid vehicle, and determining a consumable power of the target hybrid vehicle according to the target remaining power and the current remaining power; if the consumable power is greater than the consumed power, controlling the target hybrid vehicle to drive to the destination in a manner of consuming only battery power; wherein the consumed power is determined according to the path information of the target hybrid vehicle from the current position to the destination obtained from a cloud service platform.

[0056] In this way, the technical solution provided by the present application can determine the target balance value of the battery by obtaining the result information of whether the target hybrid vehicle is charged at the destination, manage the power mode of the plug-in hybrid vehicle according to the target balance value, and improve the utilization rate of the battery power.

[0057] To facilitate the understanding of the present application, the technical solution provided by the present application will be described in detail below in conjunction with specific embodiments.

[0058] See also Figure 1 , Figure 1 A flow chart of a hybrid vehicle power mode management method provided in an embodiment of the present application, such as Figure 1 As shown in, the management method comprises:

[0059] S101, obtaining result information of whether a target hybrid vehicle is charged at a destination after driving from a current position to a destination, determining a target balance value of a state of charge of a battery of the target hybrid vehicle according to the result information, and determining a remaining power corresponding to the target balance value as a target remaining power;

[0060] In this step, the user sets the driving destination and whether to charge at the destination through the mobile phone or the large screen on the vehicle, and sends the information to the cloud service platform through wireless communication. The cloud service platform uses the result information of whether to charge at the destination set by the user on the mobile phone or the large screen on the vehicle and plans the best navigation route, and transmits the route information such as route speed limit, congestion, distance, etc. to the controller (VCU) through the vehicle network system (Tbox). The VCU obtains the information forwarded by the Tbox through the internal network of the vehicle, and through the intelligent energy control method, the battery state of charge (SOC) is minimized when the vehicle arrives at the destination for external charging, thereby maximizing the economic and environmental benefits.

[0061] Here, the state of charge is the ratio of the remaining power of the battery to the total power of the battery; the target balance value is the ratio of the remaining power corresponding to the balance between the remaining power of the battery during charging and the remaining power during discharging of the target hybrid vehicle to the total power of the battery.

[0062] It should be noted that the target balance value is determined by the following steps:

[0063] 1) If the result information indicates that the target hybrid vehicle is charged at the destination, a preset minimum threshold is determined as a target balance value of the state of charge of the battery of the target hybrid vehicle;

[0064] In this step, the result information indicates charging at the destination. At this time, the preset minimum threshold is determined as the target balance value. The preset minimum threshold is the ratio of the minimum remaining battery power required for the normal operation of the vehicle to the total battery power determined through multiple experiments; illustratively, if charging is performed at the destination, the SOC balance value is determined to be 5% of the preset minimum threshold. When plug-in external charging is performed after the vehicle is controlled to arrive at the destination, the battery's SOC balance value (target balance value) reaches the minimum, so that the battery power of the plug-in hybrid vehicle can be fully utilized, and there is no need to frequently consume fuel to recharge the battery.

[0065] 2) If the result information indicates that the target hybrid vehicle is not charged at the destination, a target balance value of the state of charge of the battery corresponding to the target hybrid vehicle is determined from a mapping relationship between multiple pieces of operation information and the target balance value according to current operation information of the target hybrid vehicle.

[0066] In this step, the operating information includes battery temperature, battery health and driving environment; if the result information indicates that charging is not to be performed at the destination, the corresponding target balance value is determined based on the mapping relationship between the operating information such as battery temperature, battery health and driving environment and the target balance value.

[0067] S102, obtaining a current remaining power of a battery of the target hybrid vehicle, and determining a consumable power of the target hybrid vehicle according to the target remaining power and the current remaining power;

[0068] In this step, the current remaining power of the battery is obtained from a battery management system (BMS), and the target remaining power is subtracted from the current remaining power to obtain the consumable power.

[0069] S103: If the consumable power is greater than the consumed power, controlling the target hybrid vehicle to travel to the destination by consuming only battery power.

[0070] In this step, the power consumption is determined based on the path information of the target hybrid vehicle from the current position to the destination obtained from the cloud service platform; the planned path information is obtained from the cloud service platform through the Internet of Vehicles system, and the power consumption required for the target hybrid vehicle to travel from the current position to the destination is determined based on the path information, and it is judged whether the consumable power is greater than the consumed power. If so, the vehicle is controlled to run in pure electric mode, that is, it drives to the destination in a manner that only consumes battery power; if not, the optimal path for pure electric and hybrid driving is planned based on the path information.

[0071] In this step, the power consumption is determined by the following steps:

[0072] 1) Obtaining the current voltage and current of the battery of the target hybrid vehicle;

[0073] In this step, the battery voltage U, current I and other parameters are obtained through the CAN bus.

[0074] 2) determining an average amount of electricity consumed by the target hybrid vehicle for each preset distance traveled according to the current voltage and current current and the predicted travel time corresponding to each preset distance included in the predicted travel distance in the path information;

[0075] In this step, the unit power consumed by the target hybrid vehicle for each preset distance traveled is determined based on the current voltage, the current current and the predicted driving time corresponding to each preset distance included in the predicted driving distance in the path information, and the average power consumed by the target hybrid vehicle for each preset distance traveled is determined based on the number of multiple preset distances and the unit power consumed for each preset distance.

[0076] For example, when the preset distance is one kilometer, the unit power consumed per kilometer is calculated as follows:

[0077]

[0078] Among them, E i is the unit power consumed by the preset distance of the i-th segment, t i is the starting time of each kilometer, t i+1 is the end time of each kilometer, U is the current voltage, I is the current current, d t The time it takes to travel the preset distance. The average power consumption per kilometer is determined based on the unit power consumption per kilometer. The formula is as follows:

[0079]

[0080] Among them, E avg is the average power consumed per preset distance traveled, and n is the number of multiple preset distances.

[0081] 3) Determine the amount of power that the target hybrid vehicle needs to consume to reach the destination based on the average power and the predicted driving distance not traveled in the route information.

[0082] In this step, the power consumption is determined based on the average power and the predicted driving distance not traveled in the route information. The formula is as follows:

[0083] E con =E avg *L;

[0084] Among them, E con is the power consumption, and L is the predicted driving distance that has not been driven.

[0085] Please note that Figure 2 , Figure 2 A flowchart of another hybrid vehicle power mode management method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown in , the management method also includes:

[0086] S201: If the consumable power is not greater than the consumed power, determining whether the current driving speed of the target hybrid vehicle is less than a vehicle speed threshold;

[0087] In this step, when the consumable power is not greater than the consumed power, the optimal pure electric and hybrid driving paths are planned according to the path information, specifically by determining whether the current driving speed of the target hybrid vehicle is less than the vehicle speed threshold.

[0088] It should be noted that the vehicle speed threshold is determined through the following steps:

[0089] 1) According to the predicted driving distance and predicted driving speed corresponding to each driving path in the path information, sorting each driving path in ascending order according to the predicted driving speed;

[0090] 2) Obtain the predicted driving distance corresponding to each segment of the sorted driving route, and accumulate the predicted driving distances in the order of the sorting;

[0091] 3) When the accumulated predicted driving distance is greater than or equal to the drivable distance of the target hybrid vehicle, the predicted driving speed corresponding to the current accumulated predicted driving distance is determined as the speed threshold of the target hybrid vehicle.

[0092] In this step, the drivable distance is determined based on the current remaining power of the battery of the target hybrid vehicle. The drivable distance of the vehicle in pure electric mode is determined based on the current remaining power obtained from the battery management system (BMS). The formula is as follows:

[0093]

[0094] Among them, L ev is the drivable distance, E re The current remaining power.

[0095] Here, according to the path information obtained from the cloud service platform, the path information includes multiple driving paths, each driving path has a corresponding predicted driving distance and predicted driving speed, and the predicted driving speeds are sorted from low to high, and the sorted driving paths are calculated and accumulated starting from the predicted driving distance of the first driving path. When the accumulated sum is greater than or equal to the drivable distance, the accumulation is stopped, and the predicted driving speed corresponding to the currently accumulated driving path is the speed threshold.

[0096] S202: If yes, control the target hybrid vehicle to travel to the destination in a manner of consuming only battery power;

[0097] In this step, when it is determined that the driving speed is less than the vehicle speed threshold, the vehicle is controlled to run in pure electric mode, that is, it drives to the destination by consuming only battery power until the driving speed and / or the vehicle speed threshold changes, and then it is re-determined whether the current driving speed of the target hybrid vehicle is less than the vehicle speed threshold.

[0098] S203: If not, control the target hybrid vehicle to travel to the destination in a manner of consuming fuel and battery power.

[0099] In this step, when it is determined that the driving speed is not less than the vehicle speed threshold, the vehicle is controlled to operate in a hybrid mode, that is, to drive to the destination by consuming fuel and battery power, until the driving speed and / or the vehicle speed threshold changes, and then it is re-determined whether the current driving speed of the target hybrid vehicle is less than the vehicle speed threshold. Here, according to the difference in the hybrid mode device of the plug-in hybrid vehicle, it can be divided into multiple situations. For example, in a series-connected device, when starting and below the vehicle speed threshold, it is driven by the electric motor only (only consuming battery power), and when the speed increases to the vehicle speed threshold, the engine and the electric motor share the power efficiently (consume fuel and battery power at the same time). This method requires a power sharing device and a generator, so the structure is complex. In a series device, the engine (consumes fuel) drives the generator to generate electricity first, and then supplies the electric motor (consumes battery power) to drive the car; in a parallel device, the engine and the motor can both drive the car (it can be driven by consuming fuel or battery power alone, or by consuming fuel and battery power at the same time).

[0100] For example, see Figure 3 , Figure 3 A logic diagram of the control power mode provided in the embodiment of the present application, such as Figure 3 As shown, the user sets the destination and whether to charge at the destination on the mobile phone or the large screen in the car, and sends the information to the cloud service platform to plan the best navigation route. The planned route information and the result information of whether to charge at the destination sent by the cloud service platform are obtained through wireless communication and the in-vehicle network. Whether to charge at the destination is determined according to the result information. If so, the vehicle's state of charge balance point is calibrated at 5%; if not, the battery state of charge balance point is calibrated according to information such as temperature, battery health, and driving environment; the consumable remaining power is determined according to the state of charge balance point and the current remaining power obtained from the battery management system, and the power to be consumed is estimated according to the route information. If the consumable remaining power is greater than the power to be consumed, the vehicle is driven to the destination in pure electric mode; if the consumable remaining power is not greater than the power to be consumed, the pure electric route and the hybrid route are planned according to the route information, and it is determined whether the current driving speed is less than the threshold. If so, the vehicle is driven in pure electric mode; if not, the vehicle is driven in hybrid mode.

[0101] A method for managing a hybrid vehicle power mode is provided in an embodiment of the present application. The method comprises: obtaining result information of whether a target hybrid vehicle is charged at a destination after traveling from a current position to a destination, determining a target balance value of a state of charge of a battery of the target hybrid vehicle according to the result information, and determining a remaining power corresponding to the target balance value as a target remaining power; wherein the target balance value is a ratio of a remaining power corresponding to a balance between a remaining power of the battery of the target hybrid vehicle during charging and a remaining power of the battery during discharging to a total power of the battery; obtaining a current remaining power of the battery of the target hybrid vehicle, and determining a consumable power of the target hybrid vehicle according to the target remaining power and the current remaining power; if the consumable power is greater than the consumed power, controlling the target hybrid vehicle to travel to the destination in a manner of consuming only battery power; wherein the consumed power is determined according to path information of the target hybrid vehicle traveling from the current position to the destination obtained from a cloud service platform.

[0102] In this way, the technical solution provided by the present application can determine the target balance value of the battery by obtaining the result information of whether the target hybrid vehicle is charged at the destination, manage the power mode of the plug-in hybrid vehicle according to the target balance value, and improve the utilization rate of the battery power.

Since the principle of solving the problem by the device in the embodiment of the present application is similar to the hybrid vehicle power mode management method in the above embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
