[0052] Before providing a detailed explanation of the vehicle control method provided in the embodiments of this application, the application scenarios and implementation environment involved in the embodiments of this application will be introduced first.

[0053] Currently, with the continuous development of the new energy vehicle sector, new energy and hybrid vehicles are gradually becoming the first choice for public transportation. Furthermore, with the advancement of vehicle intelligent control technology, new energy and hybrid vehicles are able to achieve more functions, with a particular focus on the comfort experience of drivers and passengers. Among these, vehicle reservation and travel functions are also gradually appearing in users' view.

[0054] In related technologies, customers can set their travel time via a mobile app or the vehicle's infotainment system. Once the vehicle's own conditions are met, the vehicle automatically adjusts the battery temperature and passenger compartment temperature to optimal levels before the travel time. However, currently, there is no complete control solution for scheduled trips, and it cannot effectively regulate various situations. This leads to insufficient regulation of battery and passenger compartment temperatures, or failure to monitor battery drain during the regulation process, resulting in low battery power, vehicle shutdown, and negatively impacting the user's travel experience.

[0055] Based on this, this application takes into account both the vehicle being connected to a charger and not connected to a charger, and makes reasonable adjustments in both cases to ensure that the temperature of the power battery and the passenger compartment can reach a suitable temperature as much as possible, without taking up the user's travel preparation time, and bringing the user a comfortable travel experience.

[0078] It should be noted that the application scenarios and implementation environments described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the emergence of new application scenarios and the evolution of implementation environments, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0079] The vehicle control method provided in the embodiments of this application will now be explained in detail. For ease of description, the user terminal mentioned below will be a mobile phone and a mobile APP, and the vehicle terminal will be a T-BOX.

[0080] Figure 3 This is a flowchart of a vehicle control method provided in an embodiment of this application, which is applied to the above-described implementation environment. Please refer to... Figure 3 The method includes the following steps.

[0081] Step 301: If the current time reaches the first time and the battery temperature of the vehicle's power battery is less than the first temperature threshold, then control the power battery to heat up. The first temperature threshold is used to indicate whether the power battery has reached the optimal state for travel. The first time is the duration between the scheduled travel time and the scheduled travel time.

[0082] Whether the battery temperature of the power battery is lower than the first temperature threshold is detected by the battery management system.

[0083] The first duration and the first temperature threshold are both preset, and the specific values ​​can be set according to actual application requirements. This application embodiment does not limit this.

[0084] In some embodiments, after the current time reaches the first time, the T-BOX will wake up the vehicle network. After the vehicle network is woken up, the vehicle controller will detect whether the vehicle is plugged in for charging.

[0085] In some embodiments, the methods for controlling the heating of the power battery differ depending on whether the vehicle is plugged in for charging or not. These methods will be described separately below.

[0086] In the first scenario, when the vehicle is being charged via a charging gun, the power battery is heated, and the battery temperature is monitored during the heating process. Heating is stopped when the battery temperature reaches a first temperature threshold.

[0087] When the battery management system detects that the battery temperature is lower than the first temperature threshold, it sends a high-voltage request to the vehicle controller. The vehicle controller receives the high-voltage request and sends a high-voltage approval response to the battery management system. After receiving the high-voltage approval response, the battery management system turns on the external PTC (Positive Temperature Coefficient) thermistor to heat the power battery.

[0088] Please refer to Figure 4 During the heating process, the battery management system continuously monitors the battery temperature of the power battery. When it detects that the battery temperature has not reached the first temperature threshold, it continues to control the power battery to heat up. When it detects that the battery temperature has reached the first temperature threshold, the battery management system sends a high-voltage request to the vehicle controller. Similarly, the vehicle controller receives the high-voltage request and sends a high-voltage consent response to the battery management system. After receiving the high-voltage consent response, the battery management system stops heating the power battery.

[0089] By setting a first temperature threshold, heating can be stopped when the battery temperature reaches that threshold, allowing for precise temperature regulation. Since the vehicle is charging via the charging gun at this time, the battery is continuously replenished, and there is usually no situation where the battery power is insufficient to heat the battery to the first temperature threshold.

[0090] In the second scenario, if the vehicle is not being charged via the charging gun and the state of charge (SOC) value of the power battery is greater than the first SOC threshold, the power battery is controlled to be heated. During the heating process, the SOC value and battery temperature of the power battery are monitored. Heating is stopped when the monitored SOC value is less than the second SOC threshold or the monitored battery temperature reaches the first temperature threshold. The second SOC threshold is less than the first SOC threshold.

[0091] Among them, the state of charge (SOC) value of a power battery refers to the ratio of the remaining usable charge in the battery to its capacity, which is also detected by the battery management system.

[0092] The first state threshold and the second state threshold are both preset, and the second state threshold is less than the first state threshold. The specific size is not limited in this application embodiment.

[0093] In other words, when the vehicle is not being charged through the charging gun, if the battery management system detects that the battery temperature is lower than the first temperature threshold and the state of charge of the power battery is greater than the first state threshold, it will send a high voltage request to the vehicle controller. The vehicle controller receives the high voltage request and sends a high voltage approval response to the battery management system. After receiving the high voltage approval response, the battery management system will turn on the external PTC thermistor to heat the power battery.

[0094] Please refer to Figure 5 During the heating process, the battery management system continuously monitors the state of charge (SOC) value and battery temperature of the power battery. When the SOC value is detected to be greater than the second SOC threshold and the battery temperature is detected to be less than the first temperature threshold, the power battery heating continues. When the SOC value is detected to be less than the second SOC threshold, or the battery temperature is detected to reach the first temperature threshold, the battery management system sends a high-voltage reduction request to the vehicle controller. Similarly, the vehicle controller receives the high-voltage reduction request and sends a high-voltage reduction consent response to the battery management system. After receiving the high-voltage reduction consent response, the battery management system stops heating the power battery.

[0095] By setting a first temperature threshold, a first state threshold, and a second state threshold, the battery temperature can be precisely controlled while saving power, preventing indiscriminate heating of the battery and thus avoiding excessively low battery charge. This is because the vehicle is not charging via the charging gun at this time, and the battery is not being replenished. Therefore, it is necessary to judge and monitor the battery's state of charge to prevent the vehicle from stopping operation due to excessively low battery charge.

[0096] The aforementioned scheduled travel time can be selected and set by the user or automatically set by the backend monitoring center.

[0097] In some embodiments, the scheduled travel time is set by the user. In this case, the user can set it through a mobile app or through the vehicle's infotainment screen.

[0098] If a user sets a reservation time through a mobile app, that time will be reported to the backend monitoring center. The backend monitoring center will determine the first time based on the reservation time and the first duration. When the backend monitoring center detects that the current time has reached the first time, it will wake up the T-BOX via SMS. After receiving the SMS reminder, the T-BOX will wake up the entire vehicle network.

[0099] If a user sets a reservation time through the vehicle's large screen, the vehicle system will determine the first time based on the reservation time and the first duration. When the vehicle system detects that the first time has been reached, it will also wake up the T-BOX. After receiving the reminder, the T-BOX will wake up the vehicle network.

[0100] In some embodiments, the scheduled travel time is automatically set by the backend monitoring center after it has not received the user's scheduled travel time within the scheduled time period. In this case, the backend monitoring center can count the user's previously set scheduled travel times and use the most frequently set travel time as the automatically set travel time, or use the average of all the user's set travel times as the automatically set travel time. The backend monitoring center can also count the user's previous actual departure times and determine the time range with the most concentrated actual departure times, using the average of the actual departure times within that time range as the automatically set travel time. Of course, other methods can also be used to determine the automatically set travel time, and this application embodiment does not limit this.

[0101] The reservation duration is set in advance, for example, it can be set to 24 hours. If the backend monitoring center does not receive the user's reserved travel time within 24 hours, it will automatically begin setting the reservation. The reservation duration can be set according to actual application needs, and this embodiment does not limit this.

[0102] In this way, the back-end monitoring center can automatically set the scheduled travel time, so that users can still have a comfortable travel experience even if they forget to set the scheduled travel time.

[0103] It's important to note that when a user sets a scheduled travel time via the mobile app, the backend monitoring center receives and stores the scheduled travel time data sent by the user's phone. When the user sets a scheduled travel time on the vehicle's infotainment screen, this data is captured by the T-BOX and sent to the backend monitoring center, which then receives and stores it. Additionally, the vehicle controller can detect the vehicle's actual departure time, and the T-BOX can also capture this actual departure time data via the CAN bus and send it to the backend monitoring center, which receives and stores it. Therefore, the backend monitoring center can statistically analyze both the user's previously set scheduled travel time and the actual departure time.

[0104] In some embodiments, the scheduled travel time is the travel time set after the vehicle's scheduled travel function is activated; in this case, before controlling the power battery to heat up, the method further includes: if the vehicle's scheduled travel function is activated at the current time, then the step of controlling the power battery to heat up is performed; if the vehicle's scheduled travel function is deactivated at the current time, then the step of controlling the power battery to heat up is not performed.

[0105] It should be noted that the reservation travel function can be turned on and off by the user through the mobile app, or by the user through the in-vehicle infotainment screen.

[0106] In some embodiments, if the scheduled travel function is not activated or is activated but then immediately deactivated, the vehicle network will not be activated, and therefore the step of controlling the power battery to heat up will not be executed. If the user activates the scheduled travel function but deactivates it immediately, the backend monitoring center will receive a notification from the mobile phone, but the T-BOX will not be activated, and consequently, the T-BOX will not activate the vehicle network.

[0107] In other embodiments, the reservation travel function is turned off after the first time and before the second time. At this time, the vehicle controller first detects whether the power battery is in a heating state. If it is not in a heating state, the vehicle controller sends a relevant instruction to the battery management system, instructing the battery management system not to send a high voltage request to the vehicle controller. If it is in a heating state, the battery management system continues to control the power battery to heat up until the battery heating process cycle ends or the battery temperature reaches the first threshold and then the heating stops.

[0108] Because the battery management system sends information about the battery's heating status to the vehicle controller when the battery is heating, the vehicle controller can know whether the power battery is in a heating state.

[0109] In other embodiments, the reservation travel function is turned off after a second time period, since the battery heating process cycle has ended at this time, so it does not affect the step of controlling the power battery to heat up.

[0110] It should be noted that the battery heating process cycle refers to the time period from the first time to the second time.

[0111] In some embodiments, when the vehicle controller detects that the vehicle is not in a high-voltage state during a first dwell time, the vehicle controller automatically enters a sleep state; when the battery management system detects that the vehicle is not in a high-voltage state during a second dwell time, the battery management system automatically enters a sleep state. This saves battery power. The first and second dwell times are preset and can be the same or different; their specific values ​​are not limited in this embodiment.

[0112] Step 202: If the current time reaches the second time and the vehicle's cabin temperature is not within the suitable cabin temperature range, control the vehicle's air conditioning system to adjust the cabin temperature. The suitable cabin temperature range is used to indicate whether the cabin temperature has reached the optimal state for travel. The second time is the duration between the scheduled travel time and the scheduled travel time, which is less than the first duration.

[0113] The second duration is preset and is shorter than the first duration described above; that is, step 202 follows step 201. The specific length of the second duration can be set according to actual application requirements, and this embodiment does not limit it.

[0114] In some embodiments, the vehicle network is in a sleep state before the current time reaches the second time. When the current time reaches the second time, it will be woken up again. In this case, the backend monitoring center or the vehicle's infotainment screen will wake up the T-BOX and then the vehicle network again after detecting that the current time has reached the second time, in the same way as in step 201 above, and will not be repeated here. After the vehicle network is woken up again, the vehicle controller will again check whether the vehicle is plugged in for charging.

[0115] In some embodiments, the methods for controlling the vehicle's air conditioning system to adjust the cabin temperature differ depending on whether the vehicle is plugged in for charging or not. These methods will be described separately below.

[0116] In the first scenario, when the vehicle is being charged via a charging gun, the vehicle's air conditioning system is controlled to adjust the cabin temperature, and the cabin temperature is monitored during the adjustment process. The cabin temperature adjustment is stopped when the cabin temperature is within a suitable range.

[0117] Once the current time reaches the second time, the temperature sensor in the air conditioning system will detect the temperature inside the cabin and report the detected temperature value to the automatic temperature regulator in the air conditioning system. When the automatic temperature regulator detects that the cabin temperature is not within the suitable cabin temperature range, it will send a high-voltage request to the vehicle controller. The vehicle controller receives the high-voltage request and sends a high-voltage approval response to the automatic temperature regulator. After receiving the high-voltage approval response, the automatic temperature regulator uses the power battery to adjust the cabin temperature.

[0118] Please refer to Figure 6During the heating process, the temperature sensor continuously detects and reports the cabin temperature to the automatic temperature controller. The automatic temperature controller continuously monitors the cabin temperature. When it detects that the cabin temperature is not within the suitable cabin temperature range, it continues to adjust the cabin temperature. When it detects that the cabin temperature is within the suitable cabin temperature range, the automatic temperature controller sends a high-pressure reduction request to the vehicle controller. Similarly, the vehicle controller receives the high-pressure reduction request and sends a high-pressure reduction consent response to the automatic temperature controller. After receiving the high-pressure reduction consent response, the automatic temperature controller stops adjusting the cabin temperature.

[0119] By setting a suitable cabin temperature range, the cabin temperature adjustment can be stopped once the cabin temperature is within this range, enabling precise control of the cabin temperature. Since the vehicle is charging via the charging gun at this time, the battery is continuously replenished, and there is usually no situation where the battery power is insufficient to adjust the cabin temperature to the suitable range.

[0120] In the second scenario, if the vehicle is not being charged via the charging gun and the state of charge (SOC) value of the power battery is greater than the third state threshold, the vehicle's air conditioning system is controlled to adjust the cabin temperature. During the cabin temperature adjustment process, the SOC value of the power battery and the cabin temperature are monitored. The cabin temperature adjustment is stopped when the monitored SOC value is less than the second state threshold or the monitored cabin temperature is within a suitable cabin temperature range. The second state threshold is less than the third state threshold.

[0121] The third state threshold is preset, and its specific size is not limited in this application embodiment.

[0122] In some embodiments, the third state threshold is less than the first state threshold in step 201 above. This allows for skipping the battery heating step and directly adjusting the cabin temperature when the battery charge is not very high, avoiding the inability to adjust the cabin temperature after heating the battery when the battery charge is not very high.

[0123] This is because the comfort of the cabin temperature is something users can directly perceive. Therefore, it's essential to maintain a comfortable cabin temperature to provide users with a pleasant experience. Furthermore, the battery automatically heats up when the vehicle is started. Additionally, the time required to adjust the temperature is generally longer than the battery heating time; this reduces the time users need to manually adjust the vehicle's status afterward, maximizing the savings on their travel preparation time.

[0124] When the vehicle is not charging via the charging gun, the temperature sensor reports the detected cabin temperature to the automatic temperature regulator. At the same time, the automatic temperature regulator can also receive the state of charge value detected by the battery management system via the CAN bus. When the automatic temperature regulator detects that the temperature inside the cabin is not within the suitable cabin temperature range and the state of charge value of the power battery is greater than the third state threshold, it will send a high voltage request to the vehicle controller. The vehicle controller receives the high voltage request and sends a high voltage consent response to the automatic temperature regulator. After receiving the high voltage consent response, the automatic temperature regulator uses the power battery's power to regulate the temperature inside the cabin.

[0125] Please refer to Figure 7 During cabin temperature regulation, the automatic temperature regulator continuously monitors the state of charge (SOC) of the power battery and the cabin temperature. When the SOC is detected to be greater than the second SOC threshold and the cabin temperature is not within the suitable cabin temperature range, the cabin temperature regulation continues. When the SOC is detected to be less than the second SOC threshold, or the cabin temperature is detected to be within the suitable cabin temperature range, the automatic temperature regulator sends a high-voltage request to the vehicle controller. Similarly, the vehicle controller receives the high-voltage request and sends a high-voltage consent response to the automatic temperature regulator. After receiving the high-voltage consent response, the automatic temperature regulator stops cabin temperature regulation.

[0126] By setting appropriate cabin temperature ranges, second state thresholds, and third state thresholds, the cabin temperature can be precisely controlled while saving power, avoiding indiscriminate temperature adjustments that could lead to excessively low battery levels. Similar to the second scenario in step 201 above, this occurs because the vehicle is not charging via the charging gun, and the battery is not being replenished. Therefore, it is necessary to assess and monitor the battery's state of charge (SOC) value to prevent the vehicle from stopping due to excessively low battery levels.

[0127] In some embodiments, the scheduled travel time is the travel time set after the vehicle's scheduled travel function is activated; in this case, before controlling the vehicle's air conditioning system to adjust the cabin temperature, the method further includes: if the vehicle's scheduled travel function is activated at the current time, then performing the step of controlling the vehicle's air conditioning system to adjust the cabin temperature; if the vehicle's scheduled travel function is deactivated at the current time, then not performing the step of controlling the vehicle's air conditioning system to adjust the cabin temperature.

[0128] In some embodiments, if the scheduled travel function is not activated or is activated but then immediately deactivated, the vehicle network will not be activated, and therefore the step of controlling the vehicle's air conditioning system to adjust the cabin temperature will not be executed. If the user activates the scheduled travel function but deactivates it immediately, the backend monitoring center will receive a notification from the mobile phone, but the T-BOX will not be activated, and consequently, the T-BOX will not activate the vehicle network.

[0129] In other embodiments, if the reservation travel function is turned off after the first time and before the second time, the vehicle network will not be woken up when the current time reaches the second time, and therefore the step of controlling the vehicle's air conditioning system to adjust the cabin temperature will not be executed.

[0130] In other embodiments, the scheduled travel function is turned off after a second time. At this time, the vehicle controller first checks whether the air conditioner is on. If it is not on, the vehicle controller sends a relevant instruction to the automatic thermostat, instructing the automatic thermostat not to send a high-pressure request to the vehicle controller. If it is in heating mode, the automatic thermostat continues to adjust the cabin temperature until the cabin temperature adjustment cycle ends or the cabin temperature reaches a suitable range, at which point the cabin temperature adjustment stops.

[0131] Because the automatic temperature regulator sends information about whether the air conditioning is on to the vehicle controller when adjusting the cabin temperature, the vehicle controller can know whether the air conditioning is on.

[0132] It should be noted that the cabin temperature adjustment period refers to the time between the second time and the scheduled travel time.

[0133] In some embodiments, when the automatic temperature regulator detects that the vehicle is not under high voltage during the third dwell time, the air conditioning system automatically enters a sleep state. This saves power to the battery. The third dwell time is preset and may be the same as or different from the first and second dwell times; its specific duration is not limited in this application.

[0134] In this embodiment, both scenarios—vehicle connected to charging and not connected to charging—are considered, and appropriate adjustments are made in each case. By setting a first temperature threshold and a suitable cabin temperature range, the temperature of the power battery and the cabin is precisely adjusted. By setting a first state threshold, a second state threshold, and a third state threshold, the state of charge of the power battery is determined, preventing the vehicle from stopping due to excessively low battery power. Furthermore, by setting the third state threshold to be lower than the first state threshold, the battery heating step can be skipped when the battery power is not very high, and cabin temperature can be adjusted directly, maximizing the saving of users' travel preparation time and providing them with a comfortable travel experience.

[0135] This application embodiment also allows the backend monitoring center to automatically set a new travel time if it does not receive the user's scheduled travel time within the designated time period. This ensures that users can still enjoy a comfortable travel experience even if they forget to set a travel time. Furthermore, by controlling various vehicle controllers / systems to enter a sleep state under certain conditions, power consumption can be saved.
