Description

Technical Field

[0001] This disclosure relates to a system for operating a hybrid vehicle or electric vehicle, a hybrid vehicle or electric vehicle having such a system, a method for operating a hybrid vehicle or electric vehicle, and a storage medium for implementing the method. This disclosure particularly relates to the thermal management of the drive energy storage device in a hybrid vehicle or electric vehicle, such as, for example, the thermal management of a high-voltage storage device. Background Technology

[0002] Hybrid vehicles or electric vehicles are driven by electric motors, where the necessary electrical energy is stored, for example, in a high-voltage storage device. This high-voltage storage device can be charged at home charging stations or at dedicated gas stations. Short charging times are generally advantageous for users, allowing hybrid or electric vehicles to be quickly put back into use. The long lifespan of the high-voltage storage device is also a desirable feature. Summary of the Invention

[0003] The purpose of this disclosure is to provide a system for operating a hybrid vehicle or electric vehicle, a hybrid vehicle or electric vehicle having such a system, a method for operating a hybrid vehicle or electric vehicle, and a storage medium for implementing the method, which can shorten the charging time of the drive energy storage device, improve the service life of the drive energy storage device, and / or increase the driving range of the hybrid vehicle or electric vehicle.

[0004] This objective is achieved through the technical solution provided in the independent claim. Advantageous design solutions are given in the dependent claims.

[0005] According to one independent aspect of this disclosure, a system for operating a hybrid vehicle or an electric vehicle is provided. The system includes: an adjustment module configured to perform thermal pre-adjustment of a drive energy storage device of the hybrid vehicle or electric vehicle prior to a charging process; and a control module. The control module is configured to: determine, based on at least one charging standard, whether a fast-charging process of the drive energy storage device is potentially imminent before driving begins; when it is determined that a fast-charging process of the drive energy storage device is potentially imminent, output a user prompt or induce a user prompt output regarding the pre-adjustment of the drive energy storage device to a user of the hybrid vehicle or electric vehicle via a user interface before driving begins; and manipulate the adjustment module such that when a corresponding user input is received at the user interface in response to a user prompt, such as confirmation of a pre-adjustment suggestion or an instruction to initiate pre-adjustment, the pre-adjustment of the drive energy storage device begins at an appropriate time period before driving begins.

[0006] According to the present invention, it predicts whether a fast charging process is about to occur. If the condition is "yes," it is meaningful to notify the user before driving begins, indicating that pre-conditioning may have already begun. The user can then initiate or confirm the pre-conditioning via appropriate input. This ensures that the drive energy storage unit has the optimal temperature for the fast charging process upon arrival at the fast charging station. In particular, it avoids the drive energy storage unit from becoming too hot or too cold, for example, due to a short starting distance. As a result, short charging times and high charging power can be achieved.

[0007] According to the implementation method, the hybrid vehicle or electric vehicle can be a battery electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV).

[0008] Hybrid vehicles or electric vehicles include an electric drive energy storage device (e.g., a battery) that can be connected to and charged at a charging station via the vehicle's or electric vehicle's charging equipment. Different charging technologies can be used to charge the electric drive energy storage device of such hybrid vehicles or electric vehicles. In the case of AC charging, the device for converting AC power to DC power for charging the electric drive energy storage device is located in the vehicle. In the case of DC charging, the AC power conversion is performed directly at the charging station.

[0009] As used within the scope of this disclosure, the term "fast charging process" refers to DC charging, in which the fast charging station itself converts alternating current to direct current and transmits the direct current to the drive energy storage device of a hybrid or electric vehicle with low loss.

[0010] In some implementations, fast charging stations can employ a so-called IU charging method. Here, charging is first performed with a constant current until approximately 80% of the charging capacity is reached. Afterward, the fast charging station uses a constant voltage. This, in particular, enables short charging times and high charging power.

[0011] As used within the scope of this disclosure, the term "thermal preconditioning" refers to adjusting the temperature of a drive energy storage device to a target temperature by heating or cooling. Here, the target temperature corresponds to the optimal temperature for charging the drive energy storage device, for example, in terms of charging time, charging power, and / or load during the charging process.

[0012] Preferably, the control module is configured to determine (e.g., based on at least one charging standard) the timing point for initiating pre-conditioning of the drive energy storage device. This timing point can be determined such that the temperature of the drive energy storage device has reached the target temperature upon arrival at the fast charging station, meaning that optimal fast charging can be performed on the drive energy storage device in terms of charging time, charging power, and / or load upon arrival at the fast charging station.

[0013] The control module uses the at least one charging standard to estimate whether a fast charging process is likely to occur. Preferably, the at least one charging standard is selected from the group consisting of: the state of charge (SoC) of the driving energy storage device, route destination, driving route, departure time, driving history, and user behavior, or a combination thereof.

[0014] The state of charge (SOC) of a driving energy storage device can indicate that a fast charging process is about to begin. In particular, a low SOC can indicate an upcoming fast charging process.

[0015] Alternatively or supplementarily, the route destination can indicate an upcoming fast-charging process. For example, one type of route destination, such as a gas station or charging station, can indicate an upcoming fast-charging process. Similarly, the distance to the route destination can indicate an upcoming fast-charging process, especially when considering the current state of charge of the driving energy storage device. The route destination can be a route destination that the user has already entered into the navigation system, or it can be identified by the system, for example, based on trip history (e.g., regular trips to gas stations or charging stations).

[0016] Alternatively or supplementally, the driving route may indicate that a fast charging process is about to begin. For example, the driving route may pass by fast charging stations frequently used by the user. The driving route may be a route that the user has already entered into the navigation system, or it may be identified by the system, for example, based on driving history (e.g., regular driving along a defined route with gas stations or charging stations).

[0017] Alternatively or supplementally, the departure time can indicate that a fast charging process is about to begin. For example, the departure time could be the time when the user typically drives to a gas station or charging station to perform the fast charging process. The departure time could be a departure time that the user has already entered into the navigation system, or it could be identified by the system, for example, based on trip history (e.g., regular trips at specific times).

[0018] Alternatively or supplementally, trip history can indicate that a fast charging process is about to begin. For example, trip history can indicate that the user typically performs fast charging at specific times and / or locations, and / or that the user performs fast charging as much as possible.

[0019] Alternatively or supplementally, user behavior can indicate that a fast charging process is about to begin. User behavior can be, for example, learned through machine learning, such as regularly traveling to a designated fast charging station.

[0020] However, this disclosure is not limited to these examples, and other charging standards that can predict or foresee upcoming fast charging processes can be used.

[0021] Preferably, the control module is configured to: determine, before driving begins, whether the temperature of the drive energy storage device is equal to or less than a first threshold or equal to or greater than a second threshold; and when it is determined that the temperature of the drive energy storage device is equal to or less than the first threshold or equal to or greater than the second threshold before driving begins or at the start of driving, output a user prompt or prompt the user to output a user prompt.

[0022] If the temperature of the drive energy storage unit is too low or too high before or at the start of driving, its fast-charging capability is limited. If the fast-charging capability is limited beyond a certain level before or at the start of driving, it may be impossible to adequately pre-condition (i.e., heat or cool) the drive energy storage unit during the time between the start of driving and arrival at a fast-charging station to ensure the target temperature and therefore optimal fast-charging capability upon arrival. By analyzing this limitation of fast-charging capability at an early point in time, pre-conditioning can begin promptly before driving begins, thereby ensuring optimal fast-charging capability, and in particular, the corresponding target temperature of the drive energy storage unit, upon arrival at the fast-charging station.

[0023] In some embodiments, the control module may be configured to: output a user prompt or induce a user prompt output to the user of the hybrid vehicle or electric vehicle when it is determined that the temperature of the drive energy storage device is equal to or less than a first threshold or equal to or greater than a second threshold before or at the start of driving, and when the state of charge of the drive energy storage device is within a predetermined range before or at the start of driving and / or upon arrival at a fast charging station. The predetermined range may, for example, be a range in which fast charging with a constant current is possible and / or particularly effective. The predetermined range may, for example, be 20% to 80% of the charging capacity.

[0024] Preferably, the control module is configured to output a user prompt or induce a user prompt output to the user of the hybrid vehicle or electric vehicle when the driving time and / or driving distance until the possibility of charging is equal to or less than a threshold. For example, for short distances, it may be impossible to adequately pre-adjust (i.e., heat or cool) the drive energy storage device during the time between the start of driving and arrival at a fast charging station to ensure the target temperature and thus optimal fast charging capability upon arrival at the fast charging station. By analyzing the driving time and / or driving distance at an earlier point in time, pre-adjustment can begin in a timely manner before the start of driving, thereby ensuring that optimal fast charging capability, and in particular the corresponding target temperature of the drive energy storage device, is available upon arrival at the fast charging station.

[0025] Preferably, the user interface is provided on the vehicle side. In particular, the control module may be configured to output user prompts to or prompt user prompts when a user, such as a driver, is inside the hybrid vehicle or electric vehicle.

[0026] The vehicle-side user interface may include at least one output device for providing user prompts and at least one input device for receiving user input. The vehicle-side user interface may, for example, be a central information output and input device for an infotainment system, such as a head-up unit or a column-to-column display. Preferably, the user interface is fixedly mounted in the vehicle.

[0027] The at least one output device may include at least one display device and / or at least one speaker. The at least one display device may include a display, particularly an LCD display, a plasma display, or an OLED display. Alternatively or supplementarily, the at least one display device may include a projection device configured to display information directly in the driver's field of vision, particularly projecting information onto the windshield.

[0028] The at least one input device may include a touch-sensitive input device, such as a touch area or touchpad, and / or a tactile input device, such as a switch (e.g., a push-button switch and / or a rotary switch) or other mechanically operable key elements.

[0029] Preferably, the user interface on the vehicle side includes or is a touchscreen, which provides the at least one output device and the at least one input device.

[0030] In other embodiments, the user interface may be a user's mobile terminal device. In particular, the control module may be configured to output user prompts to or prompt user prompts to be output when the user, such as a driver, is outside the hybrid vehicle or electric vehicle.

[0031] Preferably, the mobile terminal device is communicatively connected to the vehicle in order to implement the functions of the system according to the invention. The mobile terminal device can communicate directly with the vehicle wirelessly or via a wired connection, or indirectly via a server connection (e.g., the cloud) and / or a mobile network (e.g., an LTE network or a 5G network).

[0032] Preferably, user prompts are output and user input is received through an application or App installed on the mobile terminal device.

[0033] Preferably, the user prompt includes either a push message or a notification.

[0034] The term "mobile terminal device" specifically includes smartphones, but also includes other mobile phones or handsets, personal digital assistants (PDAs), tablet PCs, and all current and future electronic devices equipped with technologies for implementing apps.

[0035] The mobile terminal device may include at least one output device for outputting user prompts and at least one input device for receiving user input.

[0036] The at least one output device may include at least one display device and / or at least one speaker. The at least one display device may include a display, particularly an LCD display, a plasma display, or an OLED display.

[0037] The at least one input device may include a touch-sensitive input device, such as a touch area or touchpad, and / or a tactile input device, such as a switch (e.g., a push-button switch and / or a rotary switch) or other mechanically operable key elements.

[0042] According to another independent aspect of this disclosure, a method for operating a hybrid vehicle or electric vehicle is provided.

[0054] In the following text, unless otherwise stated, the same reference numerals are used for the same and equivalent elements.

[0055] Figure 1 A hybrid vehicle or electric vehicle 10 having a system 100 for operating a hybrid vehicle or electric vehicle 10 according to an embodiment of the present disclosure is schematically shown. Figure 2 A user interface 20 according to an embodiment of the present disclosure is shown schematically.

[0056] According to the implementation method, the hybrid vehicle or electric vehicle 10 can be a battery electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV).

[0057] System 100 is illustrated as being implemented in vehicle 10. However, this disclosure is not limited thereto, and a distributed system is also conceivable in which at least some components and / or functions are implemented outside of vehicle 10, for example, in a backend.

[0058] System 100 includes: an adjustment module 110 configured to perform thermal pre-adjustment of the drive energy storage unit 12 of a hybrid vehicle or electric vehicle 10 prior to a charging process; and a control module 120. The control module 120 is configured to: determine, based on at least one charging standard, whether a fast charging process of the drive energy storage unit 12 is potentially imminent before driving begins; when it is determined that a fast charging process of the drive energy storage unit 12 is potentially imminent, output a user prompt NH to a user of the hybrid vehicle or electric vehicle 10 via a user interface 20 regarding the pre-adjustment of the drive energy storage unit 12, or prompt the user to output the user prompt NH; and when a corresponding user input NE, such as confirmation of a pre-adjustment suggestion or a command to begin pre-adjustment, is received from the user at the user interface 20 in response to the user prompt NH, such that pre-adjustment of the drive energy storage unit 12 begins before driving begins.

[0059] exist Figure 1 In the example, user interface 20 is the user's mobile terminal device. Mobile terminal device 20 can be used, for example, to communicate with the user when the user is outside the hybrid vehicle or electric vehicle 10.

[0060] Mobile terminal device 20 can communicate with hybrid vehicle or electric vehicle 10 via communication connection KV to implement the functions of system 100. Mobile terminal device 20 can communicate directly with hybrid vehicle or electric vehicle 10 wirelessly or via wired connection, or indirectly wirelessly via server connection (e.g., cloud) and / or mobile network (e.g., LTE network or 5G network).

[0061] In some implementations, the output of user prompts (NH) and the reception of user input (NE) are performed through an application or App installed on the mobile terminal device 20. User prompts (NH) may include, for example, push notifications.

[0062] However, this disclosure is not limited to mobile terminal devices, and in other embodiments, the user interface may be provided on the vehicle side. For example, when the user is in a hybrid or electric vehicle 10, the vehicle-side user interface can be used to communicate with the user.

[0063] The control module 120 uses the at least one charging standard to estimate whether a fast charging process is likely to occur. The at least one charging standard may include, for example, the state of charge of the vehicle energy storage 12 and / or route destination and / or driving route and / or departure time and / or driving history.

[0064] The state of charge (SOC) of the drive energy storage device 12 can indicate that a fast charging process is about to begin. In particular, a low SOC can indicate an upcoming fast charging process.

[0065] Alternatively or supplementally, the route destination can indicate that a fast charging process is imminent. For example, a route destination such as a gas station or charging station can indicate an upcoming fast charging process. Similarly, the distance to the route destination can indicate an upcoming fast charging process, especially when considering the current state of charge of the drive energy storage unit 12. The route destination can be a route destination that the user has already entered into the navigation system, or it can be identified by system 100, for example, based on trip history (e.g., regular trips to gas stations or charging stations).

[0066] Alternatively or supplementally, the driving route may indicate that a fast charging process is about to begin. For example, the driving route may pass by fast charging stations frequently used by the user. The driving route may be a route that the user has already entered into the navigation system, or it may be identified by system 100, for example, based on driving history (e.g., regular driving along a defined route with gas stations or charging stations).

[0067] Alternatively or supplementally, the departure time can indicate that a fast charging process is about to begin. For example, the departure time could be the time when the user typically drives to a gas station or charging station to perform the fast charging process. The departure time could be a departure time that the user has already entered into the navigation system, or it could be identified by the system 100, for example, based on driving history (e.g., regular driving at specific times).

[0068] Alternatively or supplementally, trip history can indicate that a fast charging process is about to begin. For example, trip history can indicate that the user typically performs fast charging at specific times and / or locations, and / or that the user performs fast charging as much as possible.

[0069] Alternatively or supplementally, user behavior can indicate that a fast charging process is about to begin. This user behavior could be, for example, learned through machine learning, such as regularly driving to a designated fast charging station.

[0070] Preferably, the control module 120 is further configured to: determine, before driving begins, whether the temperature of the drive energy storage unit 12 is equal to or less than a first threshold or equal to or greater than a second threshold before or at the start of driving; and if it is determined that the temperature of the drive energy storage unit 12 is equal to or less than the first threshold or equal to or greater than the second threshold before or at the start of driving, output a user prompt NH to the user of the hybrid vehicle or electric vehicle 10, or prompt the user to output a user prompt NH.

[0071] If the temperature of the drive energy storage unit 12 is too low or too high before or at the start of driving, its fast-charging capability is limited. If the fast-charging capability is limited beyond a certain level before or at the start of driving, it may be impossible, for example, to adequately pre-regulate (i.e., heat or cool) the drive energy storage unit 12 during the time between the start of driving and arrival at the fast-charging station to ensure the target temperature and thus optimal fast-charging capability upon arrival at the fast-charging station. By analyzing this limitation of fast-charging capability at an early point in time, pre-regulation can begin promptly before driving begins, thereby ensuring that optimal fast-charging capability, and in particular the corresponding target temperature of the drive energy storage unit 12, is present upon arrival at the fast-charging station.

[0072] In some embodiments, the control module 120 may be configured to: output a user prompt NH to the user of the hybrid vehicle or electric vehicle 10 or prompt the user to output NH when it is determined that the temperature of the drive energy storage unit 12 is equal to or less than a first threshold or equal to or greater than a second threshold before or at the start of driving, and when the state of charge of the drive energy storage unit 12 is within a predetermined range before or at the start of driving and / or upon arrival at a fast charging station. The predetermined range may, for example, be a range in which fast charging with a constant current is possible and / or particularly effective. The predetermined range may, for example, be 20% to 80% of the charging capacity.

[0073] Preferably, the control module 120 is configured to output a user prompt NH or induce the user to output a user prompt NH when the driving time and / or driving distance until the possibility of charging is equal to or less than a threshold. For example, for short distances, it may be impossible to adequately pre-adjust (i.e., heat or cool) the drive energy storage unit 12 during the time between the start of driving and arrival at the fast charging station to ensure the target temperature and thus optimal fast charging capability upon arrival at the fast charging station. By analyzing the driving time and / or driving distance at an earlier point in time, pre-adjustment can begin in a timely manner before the start of driving, thereby ensuring that optimal fast charging capability, and in particular the corresponding target temperature of the drive energy storage unit 12, is available upon arrival at the fast charging station.

[0074] Figure 3 The process of a drive energy storage device for pre-adjusting a hybrid vehicle or electric vehicle according to an embodiment of the present disclosure is illustrated schematically.

[0075] Determine the user's location in box A, specifically whether the user is inside or outside the hybrid or electric vehicle.

[0076] Box B analyzes the charging station database regarding vehicle location. For example, it can identify or pinpoint fast charging stations in a specific surrounding area for a hybrid or electric vehicle.

[0077] Based on the information from boxes A and B, the fast charging process can be predicted in box C. Specifically, the probability of fast charging, the driving route to a possible fast charging station, the driving time to the fast charging station, and the departure time from the fast charging station can be determined.

[0078] In box D, information from box C can be used to estimate the temperature and state of charge of the drive energy storage unit at the end of the journey.

[0079] Evaluate the performance of pre-conditioning in box E, such as performance prediction for heating or cooling drive energy storage devices.

[0080] Determine the current temperature of the driving energy storage unit in box F.

[0081] In box G, information from boxes D (temperature and state of charge at the end of the trip), E (pre-conditioning performance), and F (current temperature of the driving energy storage unit) can be used to determine the state of the fast charging process. This state can, for example, describe immediate fast charging readiness, fast charging readiness upon arrival at a fast charging station, pre-conditioning time requirements during travel, and pre-conditioning time requirements before travel from a standstill. The state can also describe the energy requirements for pre-conditioning.

[0082] The user interface can be manipulated in box H to inform the user of the possibility of pre-adjustment before driving starts, so that the drive energy storage unit is in optimal thermal condition when arriving at a fast charging station.

[0083] In box K, for example, a push message can be sent to the user's mobile terminal device to request the user's confirmation or permission to begin pre-adjustment.

[0084] If the user is already in the vehicle, pre-adjusted customer interactions can be performed in box L via the user interface integrated into the vehicle.

[0085] Figure 4 A flowchart illustrating a method 400 for operating a hybrid vehicle or an electric vehicle according to an embodiment of the present disclosure is shown. Method 400 may be implemented by corresponding software that can be implemented by one or more processors (e.g., CPU).

[0086] Method 400 includes: in block 410, the control module of the hybrid vehicle or electric vehicle determines, based on at least one charging standard, whether a fast charging process of the drive energy storage of the hybrid vehicle or electric vehicle is potentially about to occur before driving begins; in block 420, when it is determined that a fast charging process of the drive energy storage is potentially about to occur, outputting a user prompt regarding pre-adjustment of the drive energy storage to the user of the hybrid vehicle or electric vehicle via a user interface before driving begins; and in block 430, when a corresponding user input is received at the user interface in response to the user prompt, the adjustment module of the hybrid vehicle or electric vehicle begins pre-adjustment of the drive energy storage before driving begins.

[0087] According to the present invention, it predicts whether a fast charging process is about to occur. If the condition is "yes," the user is notified before the vehicle starts moving; it may be meaningful that pre-conditioning has already begun before the vehicle starts moving. The user can then initiate or confirm the pre-conditioning via corresponding user input. This ensures that the drive energy storage unit has the optimal temperature for the fast charging process upon arrival at the fast charging station. In particular, it avoids situations where the drive energy storage unit's temperature is too high or too low, for example, due to the short starting distance. As a result, short charging times and high charging power can be achieved.

[0088] Although the invention has been further illustrated and explained in detail with reference to preferred embodiments, it is not limited to the disclosed examples, and those skilled in the art can derive other variations therefrom without departing from the scope of protection of the invention. Therefore, many possibilities of variation are apparent. It is also apparent that the exemplary embodiments mentioned are merely examples and should not be construed in any way as limiting, for example, the scope of protection, application possibilities, or configuration of the invention. Rather, the foregoing description and accompanying drawings enable those skilled in the art to embodied the exemplary embodiments, and various changes can be made by those skilled in the art, given an understanding of the disclosed inventive concept, such as in relation to the function or arrangement of individual elements mentioned in the exemplary embodiments, without departing from the scope of protection defined by the claims and their legal equivalents, such as further interpretations in the specification.
