[0001] This invention relates to the field of automotive heating technology, specifically a heating system for new energy vehicles. Background Technology

[0002] With the development and promotion of society, there are more and more electric vehicle companies and models, and people will use electric vehicles more and more in their lives. As a result, the requirements for driving comfort are also getting higher and higher. In winter, it is necessary to heat the driver's cabin.

The water pump, first solenoid valve, heating element, fourth solenoid valve, and radiator are sequentially connected in a closed loop via water pipes. The water pump is also sequentially connected to the second solenoid valve and the radiator fan via water pipes. The radiator fan is connected to the heating element. The water pump and heating element are further connected to the third solenoid valve via water pipes. The radiator is equipped with a blower. The vehicle controller controls the opening and closing of the water pump, radiator fan, and blower fan, and prevents the first and second solenoid valves from opening simultaneously, and prevents the third and fourth solenoid valves from opening simultaneously. The heating element provides heat energy to heat the vehicle.

[0004] In the use of some existing new energy heating systems, on the one hand, the heating temperature is set manually, and when the heating temperature is reached, the overall heating system of the car cannot adjust itself according to the temperature inside the car, resulting in the heating temperature exceeding the overall set temperature. On the other hand, when using the heating system, it is not possible to judge and analyze the overall heating system based on the real-time temperature inside the car, and abnormalities cannot be detected in time. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a heating system for new energy vehicles, which solves the problems of not being able to autonomously adjust the heating system based on the temperature inside the vehicle and not being able to analyze the efficiency of the heating system based on real-time temperature.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heating system for new energy vehicles, comprising:

[0007] The temperature acquisition unit is used to collect basic data of the target object and transmit the basic data of the target object to the adaptive processing unit. The target object includes new energy vehicles, and the basic data includes the vehicle interior temperature and the set temperature.

[0008] The adaptive processing unit is used to acquire and analyze the basic data of the target object being transmitted, and at the same time acquire the stored information transmitted by the information storage unit. The stored information includes the heating system working efficiency and the historical set temperature. The heating system working efficiency represents the time required to raise or lower the temperature by 1°C per unit space. At the same time, the unit determines whether the normal temperature value has been reached based on the heating system working efficiency and generates a judgment result, which includes a reached signal and a not reached signal.

[0009] An abnormal adjustment unit is used to acquire the transmitted non-reach signal and the standard temperature information stored in the information storage unit, and analyze the non-reach signal in combination with the standard temperature information to generate analysis results. The analysis results include adjustment signals and temperature holding signals. The temperature holding signal is then transmitted to the information feedback unit for further analysis of the adjustment signal.

[0010] The information feedback unit is used to acquire the transmitted temperature holding signal and display it to the operator, while also acquiring user feedback, including acceptance and rejection, and generating corresponding acceptance and rejection signals, and transmitting the acceptance and rejection signals to the information output unit.

[0011] The energy consumption early warning unit is used to acquire and analyze the transmitted unacceptable signal, and to issue an early warning based on the active energy consumption calculated from the unacceptable signal. At the same time, it generates energy consumption analysis information, which includes early warning signals and normal signals, and transmits the energy consumption analysis information to the information output unit.

[0012] The normal control unit acquires the transmitted arrival signal and simultaneously acquires the vehicle interior temperature W1 and the set temperature Wa, calculates the temperature difference between the two and records it as Wc3, where the temperature difference Wc3 = |W1 - Wa|. It then compares and analyzes the temperature difference to generate analysis information, which is transmitted to the information output unit. The analysis information includes a temperature hold signal and a monitoring signal. Specifically, the normal control unit generates the analysis information as follows: when the temperature difference Wc3 ≥ 0, the system determines that the set temperature has been exceeded and generates a temperature hold signal; when the temperature difference Wc3 < 0, the system determines that the set temperature has not been exceeded and generates a monitoring signal.

[0013] As a further aspect of the present invention, the adaptive processing unit generates the judgment result in the following specific manner:

[0014] S1: Obtain all historical set temperatures, calculate the average of the historical set temperatures and use it as the normal temperature value, which is also recorded as Wz. Then calculate the temperature difference between the vehicle interior temperature and the set temperature, Wc1, and calculate the working time of the heating system based on the temperature difference, which is recorded as T.

[0015] S2: Obtain the vehicle interior temperature at working hours of T, denoted as W1, and compare it with the normal temperature value Wz. When W1 ≥ Wz, the system determines that the vehicle interior temperature W1 exceeds the normal temperature value and generates a reach signal; conversely, when W1 < Wz, the system determines that the vehicle interior temperature W1 does not exceed the normal temperature value and generates a non-reach signal.

[0016] As a further solution of the present invention: The specific manner in which the abnormal adjustment unit generates an analysis result is as follows:

[0017] P1: Obtain the standard temperature denoted as Wb, and the standard temperature Wb is an interval value. The standard temperature represents the most suitable temperature for the human body under normal circumstances. According to Baidu search, the most suitable temperature for the human body is generally 18 - 24°C. Then compare the vehicle interior temperature W1 with the standard temperature Wb. When W1 is within Wb, the system determines that the vehicle interior temperature W1 reaches the standard temperature and generates a temperature maintenance signal; conversely, when W1 is not within Wb, the system determines that the vehicle interior temperature W1 does not reach the standard temperature and generates an adjustment signal.

[0018] P2: Then analyze the generated adjustment signal, calculate the temperature difference between the vehicle interior temperature W1 and the standard temperature Wb, denoted as Wc2, generate a temperature difference adjustment signal, and transmit the temperature difference adjustment signal to the information output unit.

[0019] As a further solution of the present invention: The specific manner in which the energy consumption warning unit generates a warning signal is as follows:

[0020] A1: Obtain the real-time working hours of the heating system, denoted as Ts, then obtain the working power of the heating system, denoted as GLs, and substitute the two into the formula NH = Ts × GLs to calculate the energy consumption NH of the heating system.

[0021] A2: Then obtain the overall energy consumption, denoted as NH1, and calculate the ratio of the energy consumption NH of the heating system to the overall energy consumption NH1 At the same time, the calculated ratio is compared with the preset value YS. When the system determines that the energy consumption of the heating system exceeds the preset value YS and generates a warning signal; conversely, when the system determines that the energy consumption of the heating system does not exceed the preset value YS and generates a normal signal.

[0022] As a further aspect of the present invention: the information output unit is used to acquire the received signal, the unreceived signal, the energy consumption analysis information and the analysis information, and display them to the operator through the display device; the information storage unit is used to store the stored information and the standard temperature information, and at the same time transmit the stored information to the adaptive processing unit and the standard temperature information to the abnormal adjustment unit.

[0023] Beneficial effects

[0024] This invention provides a heating system for new energy vehicles. Compared with existing technologies, it has the following advantages:

[0025] This invention calculates the operating time of the heating system under normal working conditions by acquiring the vehicle interior temperature and the set temperature. After the operating time is reached, the real-time temperature inside the vehicle is detected, and the system is autonomously adjusted based on the real-time temperature. Furthermore, the overall heating system efficiency is analyzed and judged based on the collected real-time temperature. The operating status of the heating system is judged by calculating the energy consumption of the heating system. An early warning signal is generated for abnormal states, so that early warning prompts can be issued in a timely manner to facilitate subsequent maintenance and solve potential problems of the heating system.

[0027] Figure 2 This is a diagram of the method of the present invention. Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to Figure 1 and Figure 2 This application provides a new energy vehicle heating system, including:

[0030] The temperature acquisition unit is used to collect basic data of the target object and transmit the basic data of the target object to the adaptive processing unit. The target object includes new energy vehicles. The basic data includes the in-vehicle temperature and the set temperature. The in-vehicle temperature is obtained through a set temperature sensor, which is a WRB-203 model 4-20mA temperature sensor. The set temperature is a user-adjusted temperature that can be directly obtained.

[0031] An adaptive processing unit is used to obtain the basic data of the target object transmitted and analyze it, and at the same time obtain the stored information transmitted by the information storage unit. The stored information includes the working efficiency of the heating system and the historical set temperature. The working efficiency of the heating system represents the time required to increase or decrease the temperature by 1°C in a unit space. At the same time, it is judged whether the normal temperature value is reached according to the working efficiency of the heating system and a judgment result is generated. The judgment result includes: a reached signal and an unreached signal. At the same time, the reached signal is transmitted to the normal adjustment unit, and the unreached signal is transmitted to the abnormal adjustment unit. The specific method of generating the judgment result is as follows:

[0032] S1: Obtain all historical set temperatures, calculate the average value of the historical set temperatures and use it as the normal temperature value, denoted as Wz. Then calculate the temperature difference Wc1 between the vehicle interior temperature and the set temperature, and calculate the working duration of the heating system according to the temperature difference, denoted as T;

[0033] S2: Obtain the vehicle interior temperature at the working duration of T, denoted as W1, and compare it with the normal temperature value Wz. When W1≥Wz, the system determines that the vehicle interior temperature W1 exceeds the normal temperature value and generates a reached signal. On the contrary, when W1<Wz, the system determines that the vehicle interior temperature W1 does not exceed the normal temperature value and generates an unreached signal.

[0034] Specifically, the historical heating records of the new energy vehicle are determined through the stored information, and the normal temperature value, that is, the comparison value, is generated according to the historical heating records. Then obtain the vehicle interior temperature W1 at T and compare it with the comparison value to judge whether the comparison value is reached.

[0035] An abnormal adjustment unit is used to obtain the transmitted unreached signal and obtain the standard temperature information stored in the information storage unit, and analyze the unreached signal in combination with the standard temperature information and generate an analysis result. The analysis result includes an adjustment signal and a temperature holding signal, and the temperature holding signal is transmitted to the information feedback unit, and the adjustment signal is further analyzed. The specific method of generating the analysis result is as follows:

[0036] P1: Obtain the standard temperature, denoted as Wb. The standard temperature Wb is an interval value. The standard temperature represents the most suitable temperature under normal human conditions. According to Baidu query, the most suitable temperature for humans is generally 18-24°C. Then compare the vehicle interior temperature W1 with the standard temperature Wb. When W1 exists within Wb, the system determines that the vehicle interior temperature W1 reaches the standard temperature and generates a temperature holding signal. On the contrary, when W1 does not exist within Wb, the system determines that the vehicle interior temperature W1 does not reach the standard temperature and generates an adjustment signal;

[0037] P2: Next, the generated adjustment signal is analyzed, the temperature difference between the vehicle interior temperature W1 and the standard temperature Wb is calculated and recorded as Wc2, and a temperature difference adjustment signal is generated and transmitted to the information output unit. The specific information output unit receives the transmitted temperature difference adjustment signal and directly controls the heating system to perform corresponding temperature adjustments until the standard temperature Wb is reached, after which a temperature hold signal is generated.

[0038] The information feedback unit acquires the transmitted temperature hold signal and displays it to the operator. It also receives user feedback, including acceptance and rejection, and generates corresponding acceptance and rejection signals, which are then transmitted to the information output unit. Specifically, the information feedback unit displays the temperature hold signal to the user and generates acceptance and rejection signals based on the user's decision. If the user chooses to accept, the system controls the heating system to maintain a constant temperature.

[0039] The information output unit is used to acquire the received and unreceived signals and display them to the operator through a display device.

[0040] In Embodiment 2, the difference between Embodiment 1 and Embodiment 2 is that the information feedback unit transmits the generated unacceptable signal to the energy consumption early warning unit, and then the energy consumption early warning unit analyzes the acquired unacceptable signal.

[0041] The energy consumption early warning unit is used to acquire and analyze transmitted unreceived signals, calculate the active energy consumption based on the unreceived signals, issue early warnings, and generate energy consumption analysis information, which includes early warning signals and normal signals. This energy consumption analysis information is then transmitted to the information output unit. The specific method for generating the early warning signal is as follows:

[0042] A1: Obtain the real-time working time of the heating system and record it as Ts, then obtain the working power of the heating system and record it as GLs, and substitute the two into the formula NH=Ts×GLs to calculate the energy consumption NH of the heating system.

[0043] A2: Next, obtain the total energy consumption as NH1, and calculate the ratio of the heating system energy consumption NH to the total energy consumption NH1. At the same time, the calculated ratio Compared with the preset value YS, when When the system determines that the energy consumption of the heating system exceeds the preset value YS, it generates an early warning signal; conversely, when the energy consumption exceeds the preset value YS, it generates an early warning signal. When the system determines that the energy consumption of the heating system does not exceed the preset value YS, it generates a normal signal. Specifically, the preset value YS represents the average energy consumption over all usage periods. Under normal circumstances, energy consumption not exceeding the preset value indicates that the heating is normal. Conversely, if the energy consumption exceeds the preset value, it indicates that there is a problem with the heating system itself, and it needs to be inspected and repaired.

[0044] The information output unit is used to acquire the transmitted energy consumption analysis information and display it to the operator through a display device.

[0045] In Embodiment 3, the difference between Embodiment 1 and Embodiment 2 is that the adaptive processing unit transmits the generated arrival signal to the normal adjustment unit, and the normal adjustment unit analyzes it.

[0046] The normal adjustment unit is used to acquire the transmitted arrival signal and simultaneously acquire the vehicle interior temperature W1 and the set temperature Wa, and calculate the temperature difference between the two as Wc3, where the temperature difference Wc3 = |W1 - Wa|. Then, the temperature difference is compared and analyzed to generate analysis information, which is transmitted to the information output unit. The analysis information includes a temperature hold signal and a monitoring signal. The specific method for generating the analysis information is as follows: when the temperature difference Wc3 ≥ 0, the system determines that the set temperature has been exceeded and generates a temperature hold signal; when the temperature difference Wc3 < 0, the system determines that the set temperature has not been exceeded and generates a monitoring signal.

[0047] Specifically, the relationship between the vehicle interior temperature and the set temperature is determined based on the calculated working time T. If the vehicle interior temperature is higher than the set temperature, further temperature regulation is needed. Conversely, if the temperature is lower than the set temperature, the working time of the heating system needs to be extended. This indicates a problem with the heating system, which resulted in the failure to reach the corresponding set temperature within the calculated time, requiring subsequent maintenance.

[0048] The information output unit is used to acquire the transmitted analysis information and display it to the operator through a display device.

[0049] Example 4, as Example 4 of the present invention, focuses on combining the implementation processes of Example 1, Example 2 and Example 3.

[0050] Some of the data in the above formulas are numerical calculations with dimensions removed, and the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0051] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
