These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0051] First, the terms involved in one or more embodiments of this specification are explained.

[0052] NVH characteristics refer to noise, vibration and harshness, referred to as NVH.

[0053] In this specification, a vehicle control method is provided. This specification also relates to a vehicle control device, a computing device, a computer-readable storage medium, and a computer program, which are described in detail one by one in the following embodiments.

[0054] Figure 1 A flow chart of a vehicle control method provided according to an embodiment of the present specification is shown, wherein the vehicle control method is applied to a battery-swap powered vehicle, wherein the vehicle comprises a control unit and a first drive system consisting of a first battery-swap battery and a drive motor, wherein the first battery-swap battery can be quickly connected to the vehicle via a locking mechanism, and the first battery-swap battery and the drive motor are electrically connected to the control unit, respectively, and the method specifically comprises the following steps.

[0055] Step 102: Acquire a first target driving position, and determine a first distance to be traveled of the vehicle according to the first target driving position and the current position of the vehicle.

[0056] Specifically, the target driving position is the destination.

[0057] A schematic diagram of a battery-swap electric vehicle provided in an embodiment of this specification is as follows Figure 2a As shown, the battery-swap electric vehicle uses the first battery-swap battery as a power source to drive the vehicle, wherein the first battery-swap battery is fixed to the vehicle through a locking mechanism and can be quickly swapped with other battery-swap batteries at the battery-swap station. However, due to the limited capacity of the first battery-swap battery, the distance that the first battery-swap battery can drive the vehicle is also limited.

[0058] Based on this, the embodiment of this specification first determines the first distance to be traveled of the vehicle based on the destination and the current position of the vehicle before driving the vehicle, that is, determines the total mileage required for the vehicle to travel from the current position to the destination, and then determines whether the battery replacement battery or the drive system needs to be replaced based on the total mileage or based on the total mileage and the remaining power of the first battery replacement battery.

[0059] In an optional implementation manner, determining the first distance to be traveled of the vehicle according to the first target driving position and the current position of the vehicle includes:

[0060] The first target driving position and the current position of the vehicle are input into a navigation system, and a route to be driven output by the navigation system and a first distance to be driven of the vehicle corresponding to the route to be driven are obtained.

[0061] Specifically, the battery-swap vehicle may be equipped with an intelligent navigation system, so the destination and the current position of the vehicle may be input into the navigation system, and the navigation system outputs the corresponding route to be traveled and the first distance to be traveled corresponding to the route to be traveled.

[0062] In actual applications, the navigation system may output at least two routes to be traveled and the distance to be traveled corresponding to each route to be traveled. In this case, the user can be instructed to select a target route from the at least two routes to be traveled, and then the distance to be traveled corresponding to the target route is determined as the first distance to be traveled of the vehicle.

[0063] Step 104: When the first distance to be traveled is greater than or equal to a preset distance threshold, a first prompt message for switching the driving system is sent to the user.

[0064] Specifically, after determining the first distance to be traveled of the vehicle, it can be determined whether the first distance to be traveled is greater than or equal to a preset distance threshold; if so, a first prompt message for switching the drive system can be sent to the user. The first prompt message is used to prompt the user to replace the first battery-swap battery with a range extender, so as to realize the replacement of the drive system from a battery-swap drive system to an extended-range drive system.

[0065] Since the capacity of the swap battery is small, it can drive the vehicle for a shorter distance. If the vehicle has a longer distance to travel, the user can be prompted to replace the swap battery with a range extender to meet the vehicle's long-distance driving needs.

[0066] In actual applications, the preset distance threshold can be determined according to actual needs and is not limited here. For example, the preset distance threshold can be set to 200km. When the first distance to be traveled is greater than or equal to 200km, it is determined that the vehicle needs to travel a long distance. In this case, in order to ensure that the vehicle has sufficient power source during driving, the user can be prompted to switch the drive system.

[0067] In an optional implementation, when the first distance to be traveled is greater than or equal to a preset distance threshold, sending a first prompt message for switching the driving system to the user includes:

[0068] When the first distance to be traveled is greater than or equal to a preset distance threshold, determining whether there is a battery swap station in the route to be traveled;

[0069] If not, a first prompt message for switching the driving system is sent to the user.

[0070] Specifically, when it is determined that the first distance to be traveled is greater than or equal to a preset distance threshold, it can also be determined whether there is a battery swap station in the route to be traveled; if not, a first prompt message for switching the drive system can be sent to the user.

[0071] In addition, if there is a battery swap station on the route to be traveled, it is also possible to combine one or at least two of the four parameters: the distance from the battery swap station to the destination, the distance from the current position of the vehicle to the battery swap station, the remaining power of the first battery swap battery, and the number of battery swap stations to determine whether the vehicle can successfully drive to the destination if other battery swap batteries are replaced at the battery swap station.

[0072] For example, if there is only one battery swap station in the route to be traveled, the first distance from the battery swap station to the current location and the second distance from the battery swap station to the destination can be determined, and then the drivable distance that can be driven by the first battery swap battery is determined based on the remaining power of the first battery swap battery, and then the relationship between the drivable distance and the first distance is judged; if the drivable distance is greater than the first distance, continue to judge whether the power of the battery swap battery after the battery swap is sufficient to drive the vehicle to the destination; if not, prompt the user to switch the drive system; if so, the user can be prompted to replace other battery swap batteries while the vehicle is traveling on the route to be traveled and passing through a battery swap station.

[0073] Step 106: In response to an unlocking instruction sent by the user based on the first prompt information, the locking mechanism is controlled to be unlocked, and when it is detected that the first battery-changing battery is replaced with a range extender, the locking mechanism is controlled to be locked, wherein the range extender and the drive motor constitute an extended-range drive system.

[0074] The range extender described in the embodiments of this specification can be configured in a battery swap station.

[0075] Specifically, after receiving the first prompt information for switching the drive system, the user can drive the vehicle to the battery swap station, and send an unlocking instruction of the locking mechanism to the vehicle when it is determined that the vehicle meets the conditions for replacing the range extender (for example, the vehicle drives to the designated area for replacing the range extender). After receiving the unlocking instruction, the vehicle controls the locking mechanism to unlock; when the locking mechanism is in the unlocked state, the first battery swap battery can be removed by the hoisting equipment, and then the range extender can be moved and placed on the locking mechanism to replace the first battery swap battery with the range extender; after the range extender is placed, the vehicle can control the locking mechanism to lock, so as to fix the range extender on the vehicle through the locking mechanism. Among them, the range extender includes a fuel tank, an engine, a generator, a battery, and a hoisting matching mechanism.

[0076] In the embodiment of this specification, after the first battery replacement battery is replaced with a range extender, the range extender can be quickly connected to the vehicle through a locking mechanism, and the range extender is electrically connected to the control unit, and the range extender and the drive motor constitute an extended-range drive system.

[0077] Step 108: Controlling the extended-range drive system to start operation through the control unit, wherein the extended-range drive system is used to generate electricity and / or drive the vehicle.

[0078] Specifically, after the first battery is replaced with a range extender, the range extender can be controlled by the control unit to start working, thereby generating electricity and / or driving the vehicle through the extended-range drive system.

[0079] In actual applications, after the first battery is replaced with a range extender, the vehicle control logic changes from an electric system to a hybrid system. The vehicle needs to identify the hybrid system, read the fuel tank fuel level signal, and recalculate the remaining mileage. In addition, it can also monitor the remaining power of the battery in the range extender and adjust the hybrid power according to the remaining power.

[0080] A schematic diagram of an extended-range power vehicle provided in an embodiment of this specification is as follows Figure 2b shown. Figure 2b In the process, the range extender uses the same lifting and matching mechanism as the battery swap battery, and can be shared with the locking mechanism used by the battery swap battery, so that the range extender and the battery swap battery can be interchanged.

[0081] In specific implementation, the battery-swap power vehicle can be a battery-swap power truck, such as a battery-swap power heavy truck, a battery-swap power heavy truck or a battery-swap power light truck, etc.

[0082] In an optional embodiment, the battery-swap power vehicle includes a battery-swap power heavy truck; the battery-swap power heavy truck consists of a front and a body, and a base is provided on the frame of the battery-swap power heavy truck, and the locking mechanism is provided on the base, and the first battery-swap battery and / or the range extender are placed between the front and the body, and fixed to the base by the locking mechanism.

[0083] Specifically, Figure 2a and 2b As shown, a base support is provided on the frame of the battery-swap heavy-duty truck, the base support is arranged between the front of the vehicle and the body, and a locking mechanism is provided on the base support, and the first battery-swap battery or range extender is fixed to the base support through the locking mechanism.

[0084] Among them, the first battery-exchange battery includes a battery, a radiator, a hoisting cooperation mechanism, etc.; the range extender includes a fuel tank, an engine, a generator, a radiator, a battery, and a hoisting cooperation mechanism, etc., and the range extender uses the same hoisting cooperation mechanism as the first battery-exchange battery.

[0085] In addition, the base may also include a high-voltage fast charging interface, which the first battery-exchange battery and the range extender can share, and can be connected to a power supply device through the high-voltage fast charging interface to charge the first battery-exchange battery or the battery in the range extender.

[0086] In the embodiments of this specification, the range extender and the battery-swap battery adopt the same structure, so they can be interchanged with the battery-swap battery. Among them, the battery-swap battery adopts a box-type structure for hoisting and battery-swap, which is arranged behind the cab of the heavy truck, on the beam, and fixed to the base through a locking mechanism. The range extender also adopts the same box-type structure for hoisting and battery-swap. When the vehicle needs to travel long distances, the battery-swap battery is removed by hoisting, and then the range extender is installed, so as to provide the vehicle with sufficient power source by exchanging electric and fossil energy.

[0087] In an optional embodiment, the vehicle also includes a second drive system consisting of a second battery-exchange battery and the drive motor, and the second drive system and the extended-range drive system can be quickly switched and serve as main power systems independently.

[0088] Specifically, when the first battery-swap battery of a battery-swap vehicle is replaced with a range extender, that is, the vehicle only includes an extended-range drive system, if the user has the need to use the battery-swap battery and the range extender at the same time or switch between them in real time, a second battery-swap battery can be configured on the vehicle. The second battery-swap battery and the drive motor constitute a second drive system, and the second drive system and the extended-range drive system can be quickly switched and used as the main power system alone.

[0089] In practical applications, the second battery replacement battery can also be fixed to the vehicle through a locking mechanism, and the locking mechanism can also be set on the base, and the base can also be set on the frame. However, the specific placement position or fixing method can be determined according to actual needs and is not limited here.

[0090] In an optional implementation, when the vehicle includes both a second drive system and an extended-range drive system, a second target driving position is acquired, and a second distance to be traveled of the vehicle is determined according to the second target driving position and the current position of the vehicle;

[0091] When the second distance to be traveled is less than a preset distance threshold, determining the drivable distance of the vehicle according to the remaining power of the second battery-exchange battery;

[0092] When the drivable distance is less than the second distance to be traveled, a prompt message for replacing the battery is sent to the user; or,

[0093] When the second distance to be traveled is greater than or equal to a preset distance threshold, sending a second prompt message for switching the driving system to the user;

[0094] In response to a drive system switching instruction sent by the user based on the second prompt information, the extended-range drive system is controlled by the control unit to start operation.

[0095] Specifically, the vehicle uses the second battery-swap battery and the range extender as power sources to drive the vehicle, wherein the second battery-swap battery is fixed to the vehicle through a locking mechanism and can be quickly swapped with other battery-swap batteries at the battery-swap station. However, due to the limited capacity of the second battery-swap battery, the distance that the second battery-swap battery can drive the vehicle is also limited.

[0096] Based on this, the embodiment of this specification first determines the second distance to be traveled of the vehicle based on the destination and the current position of the vehicle before driving the vehicle, that is, determines the total mileage required for the vehicle to travel from the current position to the destination, and then determines whether the battery replacement battery or the drive system needs to be replaced based on the total mileage or based on the total mileage and the remaining power of the second battery replacement battery.

[0097] After determining the vehicle's second distance to be driven, it can be determined whether the second distance to be driven is less than a preset distance threshold; if so, the vehicle's drivable distance can be determined based on the remaining power of the second battery-swap battery, and then the relationship between the drivable distance and the second distance to be driven can be determined; if the drivable distance is less than the second distance to be driven, the user is prompted to replace other battery-swap batteries.

[0098] In addition, when the second distance to be traveled is greater than or equal to the preset distance threshold, the user is prompted to switch the drive system, that is, to switch from the battery-swap drive system to the extended-range drive system.

[0099] As mentioned above, the preset distance threshold can be set to 200km. When the second distance to be traveled is greater than or equal to 200km, it is determined that the vehicle needs to travel a long distance. In this case, in order to ensure that the vehicle has sufficient power source during driving, the user can be prompted to switch the drive system from battery replacement to extended-range type; and when the second distance to be traveled is less than 200km, it is determined that the vehicle is traveling a short distance. In this case, the drive system can use the battery replacement type, and then the battery replacement operation can be performed when the second battery replacement battery is insufficient.

[0100] In actual applications, a drive system conversion button can be added to the vehicle to quickly realize the conversion between the extended-range drive system and the battery-swap drive system by pressing a button.

[0101] In the embodiments of this specification, users can freely and flexibly switch to drive the vehicle with an extended-range drive system or a battery-swap drive system according to the usage scenario and economy. In the battery-swap drive system mode, the vehicle displays the remaining power and mileage, and combined with the intelligent navigation system, it guides the information and distance of the battery swap station, making it easy to replace the battery for energy replenishment.

[0102] In an optional implementation, the power generation of the range extender within the preset time interval is determined according to the real-time power of the range extender within the preset time interval;

[0103] Determining the power consumption of the vehicle within the preset time interval;

[0104] In the case where it is determined that the power generation is greater than the power consumption, determining whether the remaining power of the second battery replacement battery is greater than or equal to a preset power threshold;

[0105] If yes, adjusting the real-time power according to the power consumption;

[0106] If not, the second battery exchange battery is charged by the range extender, wherein the charging amount is the difference between the power generation and the power consumption.

[0107] Specifically, the vehicle uses the second battery and the range extender as power sources. At low speed or starting stage, the vehicle relies on the second battery to provide power and the drive motor to provide power. When the battery power drops to a certain level, the range extender starts and drives the generator through the internal combustion engine to charge the battery or directly drive the vehicle.

[0108] After starting the range extender, when the vehicle is driving on a relatively smooth road, the power required is low, so the range extender can operate at a lower speed to meet the vehicle's needs. When the vehicle's speed increases or encounters an uphill section, the power required for the vehicle to drive will increase. In this case, the range extender needs to increase the speed and power to meet the higher energy demand. However, in order to maintain good NVH characteristics, the power generation strategy of the range extender electric vehicle usually does not allow the range extender to operate at high speed, so the real-time power of the range extender needs to be adjusted.

[0109] In addition, after starting the range extender, part of the electricity generated by the range extender is directly supplied to the vehicle's electric motor to maintain normal driving of the vehicle; the other part is used to charge and replenish the power of the second battery, thereby extending the vehicle's cruising range.

[0110] Based on this, after starting the range extender, the power generation within the preset time interval can be determined based on the real-time power of the range extender within the preset time interval, and then the power consumption of the vehicle within the preset time interval can be determined; if the power generation is less than the power consumption, that is, the power demand of the whole vehicle exceeds the output power of the range extender, the remaining power is supplemented by the second battery-swap battery; if the power generation is greater than the power consumption, it is determined whether the remaining power of the second battery-swap battery is greater than or equal to the preset power threshold; if so, there is no need to charge the second battery-swap battery. In this case, the real-time power of the range extender needs to be adjusted; if not, the second battery-swap battery is charged by the electric energy generated by the range extender.

[0111] The vehicle control method provided in the embodiments of the present specification is applied to a battery-swap powered vehicle, wherein the vehicle includes a control unit and a first drive system consisting of a first battery-swap battery and a drive motor, wherein the first battery-swap battery can be quickly connected to the vehicle through a locking mechanism, and the first battery-swap battery and the drive motor are electrically connected to the control unit respectively, wherein the method includes: obtaining a first target driving position, and determining a first distance to be traveled of the vehicle based on the first target driving position and the current position of the vehicle; when the first distance to be traveled is greater than or equal to a preset distance threshold, sending a first prompt message for switching the drive system to a user; in response to an unlocking instruction sent by the user based on the first prompt message, controlling the locking mechanism to unlock, and when detecting that the first battery-swap battery is replaced with a range extender, controlling the locking mechanism to lock, wherein the range extender and the drive motor constitute an extended-range drive system; controlling the start-up of the extended-range drive system by the control unit, wherein the extended-range drive system is used to generate electricity and / or drive the vehicle. Since the range extender can share the locking mechanism used by the first battery exchange battery, the range extender and the first battery exchange battery can be interchanged.
