[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that only parts related to the present invention are shown in the drawings for the convenience of description, rather than all the structures.

[0025] Figure 1 This is a schematic structural diagram of a cockpit temperature regulation system provided by an embodiment of the present invention. As Figure 1 shown, the cockpit temperature regulation system includes: a battery detection circuit 1, a cockpit temperature detection circuit 2, a control circuit 3, a seat heating control circuit 4, and a cockpit heating control circuit 5. The cockpit temperature detection circuit 2 is electrically connected to the battery detection circuit 1, the control circuit 3 is electrically connected to the cockpit temperature detection circuit 2, the seat heating control circuit 4 is electrically connected to the control circuit 3, and the cockpit heating control circuit 5 is electrically connected to the seat heating control circuit 4.

[0026] The battery detection circuit 1 detects the set parameters of the vehicle-mounted battery and generates a battery detection signal. The cockpit temperature detection circuit 2 detects the temperature inside the vehicle cockpit based on the received battery detection signal and generates a cockpit temperature signal. The control circuit 3 generates a seat heating adjustment signal based on the received cockpit temperature signal. The seat heating control circuit 4 adjusts the heating parameters of the vehicle seat according to the received seat heating adjustment signal, and generates a cockpit heating adjustment signal according to the received seat heating adjustment signal. The cockpit heating control circuit 5 adjusts the heating power of the vehicle cockpit according to the received cockpit heating adjustment signal.

[0027] Specifically, the battery detection circuit 1 detects the set parameters of the vehicle-mounted battery, generates a battery detection signal and sends it to the cockpit temperature detection circuit 2. Among them, the set parameters of the vehicle-mounted battery can be various parameters related to the working performance of the vehicle-mounted battery. The cockpit temperature detection circuit 2 detects the temperature inside the vehicle cockpit based on the received battery detection signal, generates a cockpit temperature signal and sends it to the control circuit 3. Among them, the temperature inside the vehicle cockpit can be the ambient temperature inside the vehicle cockpit. The control circuit 3 generates a seat heating adjustment signal based on the received cockpit temperature signal and sends it to the seat heating control circuit 4. The seat heating control circuit 4 adjusts the heating parameters of the vehicle seat according to the received seat heating adjustment signal, and generates a cockpit heating adjustment signal according to the received seat heating adjustment signal and sends it to the cockpit heating control circuit 5. Among them, the heating parameters of the vehicle seat can be temperature adjustment parameters of the vehicle seat, specifically, temperature adjustment parameters of a seat heater provided inside the vehicle seat. By adjusting the temperature parameters of the seat heater, the vehicle seat can be heated, thereby realizing cockpit temperature regulation. The cockpit heating control circuit 5 adjusts the heating power of the vehicle cockpit according to the received cockpit heating adjustment signal. Among them, the heating power of the vehicle cockpit can be the heating power of a cockpit heater of the vehicle.

[0028] Exemplarily, as Figure 1As shown in the figure, the working principle of the cockpit temperature regulation system is as follows: The battery detection circuit 1 can detect the set parameters related to the working performance of the vehicle-mounted battery under the current temperature condition of the vehicle, so as to determine the working performance of the vehicle-mounted battery according to the set parameters, generate a battery detection signal including the set parameter information and send it to the cockpit temperature detection circuit 2 to trigger the cockpit temperature detection circuit 2 to detect the ambient temperature inside the vehicle cockpit, generate a cockpit temperature signal including the ambient temperature information and send it to the control circuit 3. The control circuit 3 can control the seat heating control circuit 4 according to the current ambient temperature inside the vehicle cockpit, so that the seat heating control circuit 4 can adjust the heating parameters of the vehicle seat heater, and adjust the ambient temperature inside the vehicle cockpit through the seat heater. The seat heating control circuit 4 can also control the cockpit heating control circuit 5 according to the received seat heating adjustment signal, so that the cockpit heating control circuit 5 adjusts the heating power of the vehicle cockpit heater, thus avoiding excessive power consumption of the cockpit heater during the heating process.

[0029] Under normal circumstances, the vehicle-mounted battery can reach the highest working efficiency generally in the temperature range of about 10 - 35°C. When the temperature of the vehicle-mounted battery is lower than about 10°C, the working performance of the vehicle-mounted battery will be reduced. For example, the vehicle-mounted battery can only provide an output power of about 20% of the rated power. In the prior art, in a low-temperature environment, the cockpit heater is used to adjust the cockpit temperature. The power consumed by the cockpit heater can reach about 35% of the total vehicle energy consumption. For a vehicle with a larger cockpit, the power consumed by the cockpit heater is even more, further reducing the output power provided by the vehicle-mounted battery for vehicle driving. The cockpit temperature regulation system provided by the embodiments of the present invention detects the set parameters of the vehicle-mounted battery through the battery detection circuit, detects the cockpit temperature through the cockpit temperature detection circuit, and controls the seat heating control circuit according to the set parameters of the vehicle-mounted battery and the cockpit temperature through the control circuit to adjust the heating parameters of the vehicle seat, and controls the cockpit heating control circuit through the seat heating control circuit to adjust the heating power of the vehicle cockpit. Since the temperature regulation method of vehicle seat heating consumes less power, for example, the power consumed by the seat heater is usually about 0.2KW, while the temperature regulation method of vehicle cockpit heating consumes more power, for example, the power consumed by the cockpit heater is usually about 6KW. This is beneficial to reducing the output power provided by the vehicle-mounted battery for cockpit temperature regulation, increasing the output power provided by the vehicle-mounted battery for vehicle driving, improving the technical problems of reduced or limited vehicle driving force, shortened vehicle cruising range, and affecting the riding comfort and experience of passengers caused by the existing cockpit temperature regulation method. Using seat heating makes up for the problem of reduced riding comfort caused by insufficient cockpit heating adjustment, and is beneficial to enhancing the driving performance of the vehicle.

[0030] Figure 2The structural schematic diagram of another cockpit temperature regulation system provided by an embodiment of the present invention. As Figure 2 shown, optionally, on the basis of the above technical solution, the battery detection circuit 1 may be set to include: a battery power control circuit 10 and a battery temperature control circuit 11, and the battery temperature control circuit 11 is electrically connected to the battery power control circuit 10.

The battery temperature control circuit 11 detects the temperature of the vehicle-mounted battery according to the received battery power control signal and generates a battery temperature control signal. Among them, the battery detection signal includes the battery power control signal and the battery temperature control signal.

[0032] Specifically, the battery power control circuit 10 detects the power of the vehicle-mounted battery, generates a battery power control signal and sends it to the battery temperature control circuit 11. The battery temperature control circuit 11 detects the temperature of the vehicle-mounted battery according to the received battery power control signal and generates a battery temperature control signal. Among them, the battery detection signal includes the battery power control signal and the battery temperature control signal. The battery detection circuit 1 sends the battery detection signal including the battery power control signal and the battery temperature control signal to the cockpit temperature detection circuit 2, so that the cockpit temperature detection circuit 2 detects the temperature inside the vehicle cockpit according to the received battery detection signal.

[0033] Exemplarily, the battery detection circuit 1 can detect the set parameters of the vehicle-mounted battery. The set parameters may include the power of the vehicle-mounted battery and the temperature of the vehicle-mounted battery. The battery power control circuit 10 can detect the power of the vehicle-mounted battery and generate a battery power control signal to control the battery temperature control circuit 11 to detect the temperature of the vehicle-mounted battery and generate a battery temperature control signal according to the battery power. The battery detection circuit 1 can send the battery detection signal including the battery power control signal and the battery temperature control signal to the cockpit temperature detection circuit 2, so that the cockpit temperature detection circuit 2 detects the temperature inside the vehicle cockpit. In this way, the current working performance of the vehicle-mounted battery can be determined according to the remaining power of the vehicle-mounted battery and the temperature of the vehicle-mounted battery, and the cockpit temperature can be detected and adjusted accordingly to avoid excessive power consumption of the vehicle-mounted battery by the cockpit temperature regulation.

[0034] Continue to refer to Figure 2 Accordingly, on the basis of the above technical solution, the battery power control circuit 10 may be set to include: a battery power detection circuit 100 and a first comparison circuit 101. The first comparison circuit 101 includes a first comparison signal input terminal A1, a second comparison signal input terminal A2 and a first comparison result output terminal A3. The first comparison signal input terminal A1 accesses the battery power signal, and the second comparison signal input terminal A2 accesses the battery power limit signal.

[0035] The battery power detection circuit 100 detects the power of the vehicle-mounted battery and generates a battery power signal, and the battery power control circuit 10 outputs a battery power control signal through the first comparison result output terminal A3.

[0036] Specifically, the battery power detection circuit 100 detects the power of the vehicle-mounted battery, generates a battery power signal and sends it to the first comparison signal input terminal A1 of the first comparison circuit 101. The second comparison signal input terminal A2 of the first comparison circuit 101 is connected to the battery power limit signal. Among them, the battery power limit signal can be a low power limit that affects the output power of the vehicle-mounted battery. The battery power control circuit 10 outputs a battery power control signal through the first comparison result output terminal A3 of the first comparison circuit 101 and sends it to the battery temperature control circuit 11 and the cockpit temperature detection circuit 2.

[0037] Exemplarily, the first comparison circuit 101 can be a comparator. The first comparison circuit 101 can compare the input battery power signal and the battery power limit signal, and output a battery power control signal including the comparison result according to the magnitude relationship between the current battery power and the battery power limit, and send it to the battery temperature control circuit 11 and the cockpit temperature detection circuit 2, so that the battery temperature control circuit 11 detects the temperature of the vehicle-mounted battery according to the battery power control signal, or the cockpit temperature detection circuit 2 detects the temperature of the vehicle cockpit according to the battery detection signal including the battery power control signal. The battery power control signal can be a relative high-potential or low-potential signal, and the battery power control signal can trigger one of the battery temperature control circuit 11 and the cockpit temperature detection circuit 2 to work. For example, when the battery power control signal is a high-potential signal, it can trigger the cockpit temperature detection circuit 2 to work. When the battery power control signal is a low-potential signal, it can trigger the battery temperature control circuit 11 to work. For example, if the battery power limit is 15% of the vehicle-mounted battery power and the current vehicle-mounted battery power is 20%, the first comparison circuit 101 can determine that the vehicle-mounted battery power is lower than the battery power limit, and the first comparison circuit 101 can output a low-potential battery power control signal. The battery temperature control circuit 11 can be triggered by the low-potential battery power control signal to detect the temperature of the vehicle-mounted battery, and the cockpit temperature detection circuit 2 can not be triggered and does not perform temperature detection; if the battery power limit is 15% of the vehicle-mounted battery power and the current vehicle-mounted battery power is 10%, the first comparison circuit 101 can determine that the vehicle-mounted battery power is higher than the battery power limit, and the first comparison circuit 101 can output a high-potential battery power control signal. The cockpit temperature detection circuit 2 can be triggered by the high-potential battery power control signal to detect the cockpit temperature, and the battery temperature control circuit 11 can not be triggered and does not work.

[0038] Continue to refer to Figure 2, correspondingly, based on the above technical solution, the battery temperature control circuit 11 can be set to include: a battery temperature detection circuit 110 and a second comparison circuit 111. The battery temperature detection circuit 110 is electrically connected to the first comparison result output terminal A3. The second comparison circuit 111 includes a third comparison signal input terminal B1, a fourth comparison signal input terminal B2, and a second comparison result output terminal B3. The third comparison signal input terminal B1 receives the battery temperature signal, and the fourth comparison signal input terminal B2 receives the battery temperature limit signal.

[0039] The battery temperature detection circuit 110 detects the temperature of the vehicle-mounted battery according to the received battery power control signal and generates a battery temperature signal. The battery temperature control circuit 11 outputs a battery temperature control signal through the second comparison result output terminal B3.

[0040] Specifically, the battery power control circuit 10 outputs a battery power control signal to the battery temperature detection circuit 110. The battery temperature detection circuit 110 detects the temperature of the vehicle-mounted battery according to the received battery power control signal, generates a battery temperature signal and sends it to the third comparison signal input terminal B1 of the second comparison circuit 111. The fourth comparison signal input terminal B2 of the second comparison circuit 111 receives the battery temperature limit signal. Among them, the battery temperature limit signal can be the low-temperature limit that affects the output power of the vehicle-mounted battery. The battery temperature control circuit 11 outputs a battery temperature control signal through the second comparison result output terminal B3 and sends it to the cockpit temperature detection circuit 2.

[0041] Exemplarily, the battery temperature detection circuit 110 detects the temperature of the vehicle-mounted battery according to the received battery power control signal, generates a battery temperature signal and sends it to the second comparison circuit 111. The second comparison circuit 111 can be a comparator. The second comparison circuit 111 can compare the input battery temperature signal with the battery temperature limit signal, and output a battery temperature control signal including the comparison result according to the magnitude relationship between the current battery temperature and the battery temperature limit, and send it to the cockpit temperature detection circuit 2, so that the cockpit temperature detection circuit 2 detects the temperature of the vehicle cockpit according to the battery detection signal. The battery temperature control signal can be a relatively high-potential or low-potential signal. For example, if the battery temperature limit is 5°C and the current vehicle-mounted battery temperature is 2°C, the second comparison circuit 111 can determine that the vehicle-mounted battery temperature is lower than the battery temperature limit, and the second comparison circuit 111 can output a high-potential battery temperature control signal. The cockpit temperature detection circuit 2 can be triggered by the high-potential battery temperature control signal to detect the cockpit temperature; if the battery temperature limit is 5°C and the current vehicle-mounted battery temperature is 15°C, the second comparison circuit 111 can determine that the vehicle-mounted battery temperature is higher than the battery temperature limit, and the second comparison circuit 111 can output a low-potential battery temperature control signal. The cockpit temperature detection circuit 2 can not be triggered and does not perform temperature detection.

Among them, the required cockpit temperature signal can be a required cockpit temperature signal including the temperature required by the vehicle occupants when the vehicle occupants adjust the temperature inside the cockpit through the air-conditioning control circuit 30. The air-conditioning control circuit 30 outputs an external temperature trigger signal through the third comparison result output terminal C3 of the third comparison circuit 301 and sends it to the external temperature detection circuit 6.

[0060] Exemplarily, the third comparison circuit 301 can be a comparator.

The external temperature trigger signal can be a relatively high potential or low potential signal. For example, if the temperature in the vehicle cockpit detected by the cockpit temperature detection circuit 2 is 3°C and the cockpit temperature configured by the driver and passengers is 10°C, then the third comparison circuit 301 determines that the current temperature in the cockpit is lower than the temperature required by the driver and passengers. The third comparison circuit 301 can output a high-potential external temperature trigger signal, and the external temperature detection circuit 6 can be triggered by the high-potential external temperature trigger signal and detect the ambient temperature outside the vehicle; if the temperature in the vehicle cockpit detected by the cockpit temperature detection circuit 2 is 12°C and the cockpit temperature configured by the driver and passengers is 10°C, then the third comparison circuit 301 determines that the current temperature in the cockpit is higher than the temperature required by the driver and passengers. The third comparison circuit 301 can output a low-potential external temperature trigger signal, and the external temperature detection circuit 6 is not triggered and does not perform temperature detection.

The fourth comparison circuit 311 can compare the input external temperature signal and the required cockpit temperature signal, and output a fourth comparison result signal including a seat heating adjustment signal and a window adjustment signal according to the magnitude relationship between the external temperature signal and the required cockpit temperature signal, so as to control the seat heating control circuit 4 and the window adjustment circuit 7 according to the comparison result. The fourth comparison result signal can be a relatively high potential or low potential signal. For example, when the fourth comparison result signal is a high potential signal, it can trigger the window adjustment circuit 7 to work; when the fourth comparison result signal is a low potential signal, it can trigger the seat heating control circuit 4 to work. For example, if the ambient temperature outside the vehicle detected by the external temperature detection circuit 6 is 12°C and the cockpit temperature configured by the driver and passengers is 10°C, then the fourth comparison circuit 311 determines that the current cockpit temperature configured by the driver and passengers is lower than the ambient temperature outside the vehicle.

The fourth comparison circuit 311 can output a fourth comparison result signal with a low potential, triggering the seat heating control circuit 4 to adjust the heating parameters of the vehicle's seat heater, and adjusting the temperature inside the vehicle cockpit through the seat heater.

[0065] Figure 4 FIG. is a schematic structural diagram of another cockpit temperature adjustment system provided by an embodiment of the present invention. As Figure 4 shown, optionally, on the basis of the above technical solution, the seat heating control circuit 4 can be set to include a seat activation detection circuit 40 and a seat heating adjustment circuit 41.

[0067] Specifically, the control circuit 3 generates a seat heating adjustment signal according to the received cockpit temperature signal and sends it to the seat-on detection circuit 40 and the seat heating adjustment circuit 41 in the seat heating control circuit 4. The seat-on detection circuit 40 detects the on state of the heating function of the vehicle seat according to the received seat heating adjustment signal, generates a heating-on signal and sends it to the seat heating adjustment circuit 41. The seat heating adjustment circuit 41 adjusts the heating parameters of the vehicle seat according to the received seat heating adjustment signal and the heating-on signal, generates a cockpit heating adjustment signal according to the received seat heating adjustment signal and sends it to the cockpit heating control circuit 5.

[0068] Exemplarily, the seat heating adjustment signal may include the heating parameter information of the vehicle seat to be adjusted, specifically, it may be the gear adjustment information of the vehicle seat heater. The heating-on signal may include the information of the on or off state of the heating function of the vehicle seat, specifically, it may be the information of the on or off of the vehicle seat heater. For example, if the information included in the seat heating adjustment signal is to increase the power gear of the seat heater by one level, the seat-on detection circuit 40 detects whether the seat heater is on according to the seat heating adjustment signal. If the seat heater is currently in the off state, the seat-on detection circuit 40 generates a heating-on signal including the current off information of the seat heater and sends it to the seat heating adjustment circuit 41. The seat heating adjustment circuit 41 can turn on the seat heater to adjust the cockpit temperature and generate a cockpit heating adjustment signal to trigger the operation of the cockpit heating control circuit 5. If the information included in the seat heating adjustment signal is to increase the power gear of the seat heater by one level and the seat-on detection circuit 40 detects that the seat heater is currently on, the seat heating adjustment circuit 41 can directly increase the power gear of the seat heater by one level to adjust the cockpit temperature and generate a cockpit heating adjustment signal to trigger the operation of the cockpit heating control circuit 5.

The cockpit heating control circuit 5 is electrically connected to the control circuit 3. The cockpit heating power detection circuit 50 is electrically connected to the seat heating control circuit 4 and the control circuit 3. The cockpit heating power adjustment circuit 51 is electrically connected to the control circuit 3.

[0070] The cockpit heating power detection circuit 50 detects the actual power of the cockpit heating according to the received cockpit heating adjustment signal, generates a power feedback signal and sends it to the control circuit 3. The control circuit 3 adjusts the output power adjustment signal according to the power feedback signal. The cockpit heating power adjustment circuit 51 adjusts the power of the cockpit heating according to the received power adjustment signal.

[0071] Specifically, the seat heating control circuit 4 generates a cabin heating adjustment signal and sends it to the cabin heating control circuit 5. The cabin heating power detection circuit 50 in the cabin heating control circuit 5 detects the actual power of the cabin heating according to the received cabin heating adjustment signal, generates a power feedback signal and sends it to the control circuit 3. The control circuit 3 adjusts the output power adjustment signal according to the received power feedback signal and sends it to the cabin heating power adjustment circuit 51. The cabin heating power adjustment circuit 51 adjusts the power of the cabin heating according to the received power adjustment signal.

[0072] Exemplarily, the seat heating control circuit 4 generates a cabin heating adjustment signal and sends it to the cabin heating control circuit 5, which can trigger the cabin heating power detection circuit 50 to detect the current actual power of the cabin heater. The control circuit 3 can generate a power adjustment signal according to the current actual power of the cabin heater and adjust the current power of the cabin heater through the cabin heating power adjustment circuit 51. For example, after the control circuit 3 controls the seat heating control circuit 4 to adjust the seat heater to start working, it can control the cabin heating power adjustment circuit 51 to reduce the power of the cabin heater according to the actual power of the cabin heater. In this way, the cabin temperature can be adjusted by the seat heater, and the output power of the vehicle battery consumed by the cabin heater can be reduced, ensuring the driving performance of the vehicle and improving the riding comfort and experience of the passengers.

[0073] Optionally, continuing to refer to Figure 4 , on the basis of the above technical solution, the control circuit 3 can also be set to include a fifth comparison circuit 32. The fifth comparison circuit 32 includes a ninth comparison signal input terminal E1, a tenth comparison signal input terminal E2, and a fifth comparison result output terminal E3. The ninth comparison signal input terminal E1 is connected to the power feedback signal, and the tenth comparison signal input terminal E2 is connected to the heating power limit signal.

[0074] The control circuit 3 outputs a power adjustment signal through the fifth comparison result output terminal E3.

[0075] Specifically, the cabin heating power detection circuit 50 in the cabin heating control circuit 5 detects the actual power of the cabin heating according to the received cabin heating adjustment signal, generates a power feedback signal and sends it to the ninth comparison signal input terminal E1 of the fifth comparison circuit 32. The tenth comparison signal input terminal E2 is connected to the heating power limit signal. Among them, the actual power of the cabin heating can be the actual power of the cabin heater, and the heating power limit signal can include the heating power limit information of the cabin heater. The control circuit 3 outputs a power adjustment signal through the fifth comparison result output terminal E3 and sends it to the cabin heating power adjustment circuit 51. The cabin heating power adjustment circuit 51 adjusts the power of the cabin heating according to the received power adjustment signal.

[0076] Exemplarily, the fifth comparison circuit 32 can be a comparator. The fifth comparison circuit 32 can compare the input power feedback signal with the heating power limit signal, and output a power adjustment signal including a comparison result according to the magnitude relationship between the power feedback signal and the heating power limit signal, so as to control the cabin heating power adjustment circuit 51 to adjust the power of the cabin heater according to the comparison result. The power adjustment signal can be a relatively high potential or low potential signal. For example, if the heating power limit of the cabin heater is 20% of the maximum heating power of the cabin heater, and the actual power of the cabin heater fed back by the cabin heating power detection circuit 50 is 25% of the maximum heating power of the cabin heater, then the fifth comparison circuit 32 determines that the current actual power of the cabin heater is greater than 20% of the maximum heating power. The fifth comparison circuit 32 can output a high-potential power adjustment signal, and the cabin heating power adjustment circuit 51 can be triggered by the high-potential power adjustment signal to reduce the current power of the cabin heater by 5% to avoid excessive power consumption of the in-vehicle battery by the cabin heater; if the actual power of the cabin heater fed back by the cabin heating power detection circuit 50 is 15% of the maximum heating power of the cabin heater, then the fifth comparison circuit 32 determines that the current actual power of the cabin heater is less than 20% of the maximum heating power. The fifth comparison circuit 32 can output a low-potential power adjustment signal, and the cabin heating power adjustment circuit 51 can not be triggered and does not work. When the power consumed by the cabin heater is very low, no adjustment is required to ensure the cabin temperature adjustment performance.
