[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0027] Combine the following Figures 1 to 4 A vehicle heating control system and a passenger vehicle according to some embodiments of the present invention are described.

[0028] like Figure 1 As shown, a vehicle heating control system proposed in one embodiment of the utility model is applied to the water heating system of a passenger vehicle. Here, the passenger vehicle can be a new energy passenger vehicle, and the vehicle heating control system can be set on the basis of its existing water heating system to reduce the heating hardware cost of the passenger vehicle.

[0029] Specifically, the vehicle heating control system includes a return water temperature sensor T1, an electric heater and a heating controller; wherein the return water temperature sensor T1 is arranged at the water inlet of the fuel heater of the water heating system, and is used to collect the return water temperature information of the water heating system; here, the return water temperature sensor T1 can be arranged in the water inlet of the fuel heater, or other positions capable of collecting the return water temperature flowing into the water inlet of the fuel heater. Furthermore, the electric heater is a variable power electric heater, wherein the variable power electric heater is an electric heater with variable heating power.

[0030] Further, the water inlet of the electric heater is connected to the water outlet of the fuel heater, and the water outlet of the electric heater is connected to the water inlet of the in-vehicle radiator of the water heating system, so as to heat the water flowing out of the water outlet of the fuel heater; here, the water flowing out of the water outlet of the fuel heater can flow into the electric heater, so that the electric heater can heat the water flowing out of the water outlet of the fuel heater. Further, the water heated by the electric heater can flow into the in-vehicle radiator to heat the passenger vehicle.

[0031] Furthermore, the heating controller is connected to the return water temperature sensor T1, the fuel heater and the electric heater respectively, and is used to receive the return water temperature information, and control the operation status of the fuel heater and the electric heater based on the return water temperature information. Here, the heating controller can be a computer with a certain computing power, and a temperature control program in the prior art can be set inside it to compare the return water temperature information with a preset return water temperature value. When the return water temperature information is less than or equal to the preset return water temperature value, the fuel heater is turned on to rapidly increase the water temperature. When the return water temperature information is greater than the preset return water temperature value, the fuel heater is turned off and the electric heater is turned on to reduce fuel consumption.

[0032] It should be noted that the selection of the return water temperature sensor, the electric heater and the heating controller can be determined according to the actual situation, and this embodiment does not make specific restrictions. In addition, the connection method of each device can be determined according to the specific selection of the device, and this embodiment does not make specific restrictions. The function of the vehicle heating control system provided in this embodiment is mainly realized through the circuit connection relationship between each module, and does not rely on the program module in a certain module. In addition, each module in the vehicle heating control system can be realized by an analog circuit or a digital circuit, and for a heating controller that can be implanted with a program module, the realization of its module function can be realized by the program module provided by the prior art.

[0033] The embodiment of the utility model proposes a vehicle heating control system, which adds a return water temperature sensor, an electric heater and a heating controller to the existing water heating system of a passenger vehicle. The return water temperature sensor is arranged at the water inlet of the fuel heater, and is used to collect the return water temperature information of the water heating system; the water inlet of the electric heater is connected to the water outlet of the fuel heater, and the water outlet of the electric heater is connected to the water inlet of the radiator in the vehicle, and is used to heat the water flowing out of the water outlet of the fuel heater; the heating controller is respectively connected to the return water temperature sensor, the fuel heater and the electric heater, and is used to receive the return water temperature information, and control the operation state of the fuel heater and the electric heater based on the return water temperature information. In the technical solution of the present application, the heating controller can determine whether the return water temperature of the water heating system is too low. When the return water temperature of the water heating system is too low, the fuel heater is controlled to be in a heating state to quickly heat the water in the water heating system. After the return water temperature rises, the fuel heater is turned off and the electric heater is turned on to keep the water in the water heating system warm, so as to reduce fuel consumption and reduce the energy consumption of the water heating system of the passenger vehicle.

[0034] In one embodiment, Figure 2 As shown, the heating controller includes a single-chip microcomputer, a first voltage comparator and a first power supply; wherein the single-chip microcomputer is an integrated circuit chip, which adopts very large-scale integrated circuit technology to integrate a central processing unit CPU with data processing capability, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt system, timer / counter and other functions into a silicon chip to form a small and complete microcomputer system, which can integrate relevant control programs and is widely used in the field of industrial control.

[0035] Furthermore, the first voltage comparator is a voltage comparator. When the voltage received at the "+" extreme end of the voltage comparator, i.e., the non-inverting input end, is greater than the voltage received at the "-" extreme end, i.e., the inverting input end, the output end of the voltage comparator outputs a high-level signal. When the voltage received at the "+" extreme end of the voltage comparator is less than the voltage received at the "-" extreme end, the output end of the voltage comparator outputs a low-level signal.

[0036] Furthermore, the single chip microcomputer has a remote communication port for connecting to a remote host computer (not shown in the figure) to establish a communication connection with the host computer. The host computer can be a computer terminal device arranged at the driver's position of the passenger vehicle, so that the driver can control the vehicle's heating control system based on the host computer, thereby improving the controllability of the vehicle's heating control system.

[0037] Further, the first power supply can be connected to an external power supply (not shown in the figure) to obtain power supply. Further, the first analog temperature sensor is an analog temperature sensor, that is, a voltage output temperature sensor. When the ambient temperature of the analog temperature sensor changes, the voltage output by the voltage output pin of the analog temperature sensor will also change accordingly. Specifically, when the ambient temperature of the analog temperature sensor increases, the voltage output by the voltage output pin of the analog temperature sensor will also increase accordingly. Here, the power pin of the first analog temperature sensor can be connected to an external power supply to obtain power supply, and the voltage is output to the outside by the voltage output pin. Further, the model of the first analog temperature sensor can be a TMP35 temperature sensor, a TMP36 temperature sensor, or a TMP37 temperature sensor.

[0038] Specifically, the non-inverting input terminal of the first voltage comparator is connected to the voltage output pin of the first analog temperature sensor, and the inverting input terminal of the first voltage comparator is connected to the voltage output terminal of the first power supply.

[0039] Wherein, the first power supply is used to output a power supply voltage of a first preset voltage value; here, the first preset voltage value is used to simulate the voltage output by the first analog temperature sensor when it is at a preset return water temperature value that requires the fuel heater to be turned on for rapid heating. As an example, if the preset return water temperature value is 20 degrees, and the voltage value output by the first analog temperature sensor is 0.2V when it is in an environment of 20 degrees, then the voltage value output by the first power supply can be preset to 0.2V. At this time, if the return water temperature information collected by the first analog temperature sensor is greater than 20 degrees, the voltage value output by its voltage output pin is greater than 0.2V. Conversely, if the return water temperature information collected by the first analog temperature sensor is less than 20 degrees, the voltage value output by its voltage output pin is less than 0.2V.

[0040] Furthermore, the output end of the first voltage comparator is connected to the first signal receiving end of the single-chip microcomputer, and the single-chip microcomputer is also used to put the fuel heater into a heating state when a low-level signal is received from the first signal receiving end; as an example, the preset return water temperature value is 20 degrees, and the voltage value output by the first power supply is 0.2V; if the output end of the first voltage comparator outputs a low-level signal, it means that the return water temperature information collected by the first analog temperature sensor is less than 20 degrees, and the fuel heater needs to be started to quickly provide heating.

[0041] Furthermore, the single chip microcomputer is also used to stop the fuel heater and operate the electric heater when a high level signal is received from the first signal receiving end. As an example, the return water temperature is preset to be 20 degrees, and the voltage value output by the first power supply is 0.2V; if the output end of the first voltage comparator outputs a high level signal, it means that the return water temperature information collected by the first analog temperature sensor is greater than 20 degrees, and the fuel heater can be turned off and heated by the electric heater to save fuel.

[0042] The embodiment provided in the present application can determine whether the return water temperature meets the heating standard based on a simple circuit structure. When the return water temperature meets the heating standard, the fuel heater is turned off and the electric heater is used for heating to reduce the heating fuel consumption of passenger vehicles.

[0043] In one embodiment, Figure 3 As shown, the vehicle heating control system further includes a second analog temperature sensor T2. Further, the second analog temperature sensor T2 is disposed between the water outlet of the electric heater and the in-vehicle radiator, and is used to collect water outlet temperature information of water flowing out of the water outlet of the electric heater; here, the second analog temperature sensor T2 can be disposed in the water outlet of the electric heater, or in other locations where the water outlet temperature of water flowing out of the water outlet of the electric heater can be collected.

[0044] Further, such as Figure 4 As shown, the heating controller also includes a second voltage comparator and a second power supply; here, the second power supply can be connected to an external power supply (not shown in the figure) to obtain power supply. Further, the second analog temperature sensor is an analog temperature sensor, that is, a voltage output temperature sensor. When the ambient temperature of the analog temperature sensor changes, the voltage output by the voltage output pin of the analog temperature sensor will also change accordingly. Specifically, when the ambient temperature of the analog temperature sensor increases, the voltage output by the voltage output pin of the analog temperature sensor will also increase accordingly. Here, the power pin of the second analog temperature sensor can be connected to an external power supply to obtain power supply, and the voltage is output to the outside by the voltage output pin. Further, the model of the second analog temperature sensor can also be a TMP35 temperature sensor, or a TMP36 temperature sensor, or a TMP37 temperature sensor. Further, the second voltage comparator can also be a voltage comparator.

[0045] Furthermore, the non-inverting input terminal of the second voltage comparator is connected to the voltage output pin of the second analog temperature sensor, and the inverting input terminal of the second voltage comparator is connected to the voltage output terminal of the second power supply, wherein the second power supply is used to output a power supply voltage of a second preset voltage value; here, the second preset voltage value is used to simulate the voltage value output by the second analog temperature sensor when it is at a preset target water outlet temperature. As an example, if the preset target water outlet temperature is set to 25 degrees, when the water outlet temperature reaches 25 degrees, the power of the electric heater is reduced to keep the water in the water heating system warm to reduce the power consumption of the electric heater. At the same time, if the second analog temperature sensor is in a 25-degree environment, if its voltage output pin outputs a 0.25V voltage, the second power supply is set to output a 0.25V voltage.

[0046] Furthermore, if the target outlet water temperature is 25 degrees, the second power supply is set to output a voltage of 0.25V, and when the second analog temperature sensor is in an environment of 25 degrees, the voltage value output by the second analog temperature sensor is 0.25V. At this time, if the outlet water temperature information collected by the second analog temperature sensor is greater than 25 degrees, the voltage value output by its voltage output pin is greater than 0.25V. Conversely, if the outlet water temperature information collected by the second analog temperature sensor is less than 25 degrees, the voltage value output by its voltage output pin is less than 0.25V.

[0047] Furthermore, the output end of the second voltage comparator is connected to the second signal receiving end of the single chip microcomputer, and the single chip microcomputer is also used to control the fuel heater to stop running and control the electric heater to run at a preset operating power when a high level signal is received from the second signal receiving end. At this time, if the voltage value output by the voltage output pin of the second analog temperature sensor is greater than 0.25V, the output end of the second voltage comparator outputs a high level, and the single chip microcomputer can send a signal to the fuel heater to stop running. The single chip microcomputer can also send a signal to the electric heater to run at low power or stop running. The embodiment provided by the present application can determine whether the outlet water temperature meets the insulation standard based on a simple circuit structure. When the return water temperature meets the insulation standard, the fuel heater is turned off and the electric heater is used to provide heat at low power to reduce the consumption of heating fuel and electric energy for passenger vehicles. Here, the power of the preset operating power can be determined according to actual conditions.

[0048] In one embodiment, the heating controller further comprises a human-machine interaction interface; a data interaction terminal of the human-machine interaction interface is connected to a data interaction terminal of the single-chip computer. Here, the human-machine interaction interface can be set at the driver's seat or other positions, so that relevant operators can control the vehicle's heating control system based on the human-machine interaction interface.

[0049] In one embodiment, the vehicle heating control system further includes an alarm prompt unit; the signal receiving end of the alarm prompt unit is connected to the alarm output end of the single chip microcomputer, and the alarm prompt unit is a buzzer and / or a flash light. The embodiment provided by the present application can enable the single chip microcomputer to have an alarm capability, provide a hardware basis for performing alarm work, so that relevant staff can set an alarm program in the single chip microcomputer, and expand the application scenarios of the vehicle heating control system.

[0050] On the other hand, an embodiment of the present invention provides a passenger vehicle, comprising the vehicle heating control system as described above.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
