Description

Technical Field

[0002] In automotive applications in low-temperature winter environments, the energy efficiency of the cabin heating system has a significant impact on driving comfort. Currently, the cabin heating of traditional fuel-powered vehicles primarily relies on waste heat from the engine cooling system. When the driver activates the air conditioning heater function, the onboard heating system draws air into the heater tank via a blower, using the high-temperature coolant generated by the running engine for heat exchange, thereby heating the cabin air.

[0003] However, the cab preheating process suffers from significant time constraints. Even if the driver remotely starts the vehicle and activates the air conditioning and heating function, the driver still needs to wait for the engine cooling system's water temperature to reach a predetermined threshold before the residual heat from the water can be used for heating. During this period, the engine is idling, increasing fuel consumption and failing to provide sufficient heat to the cab in a timely manner. This prolongs waiting time in cold environments and affects travel efficiency. Summary of the Invention

[0040] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] Figure 1 This is a schematic diagram of the structure of an auxiliary heating system provided by an embodiment of the present invention. Figure 1 As shown, the arrows in the accompanying drawings can be understood as the flow direction of gas. The auxiliary heating system provided by the embodiment of the present invention includes: a throttle valve 1, arranged in the intake passage of the engine 2, for adjusting the intake volume of the engine 2. A turbocharger 3, connected to the engine 2, is used to compress the gas entering the engine 2 to produce supercharged gas; the temperature of the supercharged gas is greater than the temperature of the gas entering the turbocharger 3; the output end of the turbocharger 3 is connected to the driver's cab; a temperature sensor 4 is used to monitor the temperature in the driver's cab; a controller 5, electrically connected to the temperature sensor 4 and the throttle valve 1, is used to adjust the opening of the throttle valve 1 according to the temperature monitoring result of the temperature sensor 4, and further adjust the operating speed of the turbocharger 3.

[0043] Among them, the throttle 1 is a typical butterfly valve structure, and its core function is to adjust the cross-sectional area of the intake channel by rotating the valve plate, thereby adjusting the intake volume of the engine 2: when the valve plate is almost parallel to the axis of the intake pipe, the throttle is fully open, forming an approximately straight channel. At this time, the intake volume of the engine 2 is the largest; when the valve plate is almost perpendicular to the axis of the intake pipe, but retains a very small gap, forming a narrow annular channel, at this time the intake volume of the engine 2 is the smallest. Turbocharger 3 is an air compression device whose core function is to increase engine 2's power output by increasing the air intake. Its operating principle is based on an exhaust gas energy recovery mechanism: high-speed exhaust gas from engine 2 strikes the blades in the turbine chamber, driving them to rotate at high speed. The turbine shaft then drives the coaxial compressor impeller, drawing in and compressing outside air. Within the compressor impeller's compression channel, the air undergoes a compression process, significantly increasing its temperature and pressure, ultimately forming high-temperature, high-pressure supercharged gas. Some of this supercharged gas is fed into engine 2's cylinders to assist its operation and prevent it from stalling. Some of this supercharged gas is connected to the cab through the turbocharger's output port, accelerating the cab's temperature rise. A temperature sensor 4 monitors the cab's temperature and transmits the temperature readings to a controller 5. This temperature reading from sensor 4 adjusts the throttle valve 1's opening. A wider throttle valve 1 opening increases the amount of air entering engine 2, increasing the exhaust gas flow and energy generated by combustion. This exhaust gas energy directly drives turbocharger 3, increasing its speed.

[0044] The auxiliary heating system proposed in an embodiment of the present invention monitors the cab temperature via a temperature sensor. A controller adjusts the throttle opening based on the temperature monitoring results, altering the engine air intake and adjusting the turbocharger's operating speed. This in turn drives the turbocharger to produce high-temperature, high-pressure gas, some of which is introduced into the cab through the turbocharger's output port, achieving rapid heating. This auxiliary heating system converts the heat of compressed air into heating energy, improving the vehicle's energy efficiency and significantly reducing energy consumption and equipment loss. This system can quickly provide heat to the cab, shortening cab warm-up time and improving user comfort. It also complements the engine-operated heating method, providing a low-cost, highly reliable thermal management solution for vehicles.

[0045] Optional, Figure 2 This is a logic control diagram of an auxiliary heating system provided by an embodiment of the present invention, refer to Figure 2The controller 5 is configured to, when the temperature in the cab is within a first temperature range, adjust the opening of the throttle valve 1 to the first opening range so that the operating speed of the turbocharger 3 reaches the first speed range; when the temperature in the cab is within a second temperature range, adjust the opening of the throttle valve 1 to the second opening range so that the operating speed of the turbocharger 3 reaches the second speed range; and when the temperature in the cab is within a third temperature range, adjust the opening of the throttle valve 1 to the third opening range so that the operating speed of the turbocharger 3 reaches the third speed range;

[0046] wherein the temperature in the third temperature interval is lower than the temperature in the second temperature interval, and the temperature in the second temperature interval is lower than the temperature in the first temperature interval;

[0047] The opening value in the third opening interval is greater than the opening value in the second opening interval, and the opening value in the second opening interval is greater than the opening value in the first opening interval;

[0048] The speed value in the third speed interval is greater than the speed value in the second speed interval, and the speed value in the second speed interval is greater than the speed value in the first speed interval.

[0049] Controller 5 divides the cab temperature into first, second, and third temperature ranges, respectively, based on the highest to lowest temperature. Corresponding to these temperature ranges, throttle valve 1 is set to the first, second, and third opening ranges, respectively, based on the opening degree of throttle valve 1, and turbocharger 3 is set to the first, second, and third speed ranges, respectively, based on the operating speed of turbocharger 3. When temperature sensor 4 monitors the cab temperature, controller 5 determines the temperature range to which the temperature monitoring result belongs and adjusts throttle valve 1 to the corresponding opening range, thereby adjusting the turbocharger 3's operating speed to the corresponding speed range, generating high-temperature, high-pressure gas and thereby raising the cab temperature. This hierarchical regulation strategy, where "lower temperature, greater heating capacity," enables precise control of cab temperature and efficient energy utilization.

[0050] For example, when the temperature in the cab is between 10 and 20°C, the opening of the throttle valve 1 is 5% to 15%, and the operating speed of the turbocharger 3 is 2000 to 10000 rpm; when the temperature in the cab is between -10 and 10°C, the opening of the throttle valve 1 is 15% to 25%, and the operating speed of the turbocharger 3 is 10000 to 50000 rpm; when the temperature in the cab is between -30 and -10°C, the opening of the throttle valve 1 is 25% to 30%, and the operating speed of the turbocharger 3 is 50000 to 100000 rpm.

[0051] Optional, Figure 3 This is another schematic diagram of the auxiliary heating system provided by an embodiment of the present invention, referring to Figure 3 The auxiliary heating system also includes a throttle position sensor 6, which is used to monitor the opening of the throttle 1; the controller 5 is also electrically connected to the throttle position sensor 6, and is used to confirm the opening adjustment of the throttle 1 according to the throttle position sensor 6's throttle position opening monitoring result.

[0052] Among them, the throttle position sensor 6 is used to monitor the opening of the throttle 1 in the auxiliary heating system, and feed back the electrical signal to the controller 5, so that the controller 5 can compare the preset opening value with the actual opening value. If the actual opening value of the throttle 1 does not match the preset opening value, the control instruction is corrected in time to ensure that the throttle 1 is adjusted as expected, thereby ensuring that the speed of the turbocharger 3 reaches the target speed value, avoiding insufficient heating efficiency or energy waste due to inadequate opening adjustment, and improving the system adjustment accuracy and operation reliability.

[0053] Optional, Figure 4 This is another schematic diagram of the auxiliary heating system provided by the embodiment of the present invention, refer to Figure 4 The auxiliary heating system further includes a heat exchange device 7, which is connected to the output end of the turbocharger 3 and the cab respectively.

[0054] Among them, the high-temperature and high-pressure gas output by the turbocharger 3 is used as a heat source, and the heat is transferred to the cab through the heat exchange device 7. The heat exchange device 7 can accurately control the air supply temperature to prevent high-temperature gas from directly entering the cab and causing safety hazards. At the same time, it can ensure the air quality in the car and improve user comfort.

[0055] Optional, Figure 5 This is another schematic diagram of the auxiliary heating system provided by the embodiment of the present invention, referring to Figure 5 The auxiliary heating system further includes an air filter 8 , which is arranged in the air intake passage of the turbocharger 3 .

[0056] It can be understood that the air filter 8 is arranged in the intake channel of the turbocharger 3. Its core function is to filter out impurities such as dust and particles in the air, provide clean air for the engine 2 and the turbocharger 3, and prevent impurities from damaging the internal components of the auxiliary heating system, thereby ensuring the stable operation of the speed and heating function of the turbocharger 3.

[0057] Optionally, the controller 5 is further configured to close the connection between the output end of the turbocharger 3 and the cab when the temperature in the cab reaches a preset value and / or the vehicle is in driving state.

[0058] Among them, on the one hand, when the temperature monitored by the temperature sensor 4 reaches a preset value, the controller 5 closes the connection between the output end of the turbocharger 3 and the cab to avoid energy waste caused by excessive heating; on the other hand, when the vehicle is in a driving state, the waste heat generated by the normal operation of the engine 2 can be used to heat the cab through the heating system, and there is no need for an auxiliary heating system to consume additional energy from the turbocharger 3, thereby reducing fuel loss.

[0059] It should be noted that when the vehicle is operating in an extremely cold environment, a priority strategy can be set through the controller 5. Even when the vehicle is in motion, the auxiliary heating system can continue to operate. After the cab temperature enters a comfortable range and the engine 2 operating condition stabilizes, the connection between the output end of the turbocharger 3 and the cab is closed, thereby achieving a balance between comfort and system reliability in extreme environments.

[0060] Based on the same inventive concept, an embodiment of the present invention further provides an auxiliary heating method, specifically, Figure 6 This is a flow chart of an auxiliary heating method provided by an embodiment of the present invention, refer to Figure 6 , auxiliary heating method, including:

[0061] S110: Obtain the temperature monitoring result in the cab.

[0062] The auxiliary heating method provided in the embodiment of the present invention monitors the temperature in the cab through the temperature sensor 4 and transmits the temperature monitoring result to the controller 5 .

[0063] S120: Adjust the throttle opening according to the temperature monitoring result, and then adjust the operating speed of the turbocharger.

[0064] The controller 5 adjusts the opening of the throttle valve 1 according to the temperature monitoring result of the temperature sensor 4. The larger the opening of the throttle valve 1, the more air intake enters the engine 2, and the exhaust gas flow and energy generated by combustion increase accordingly. The exhaust gas energy directly drives the turbocharger 3 to operate, thereby increasing the speed of the turbocharger 3.

[0065] The auxiliary heating method proposed in the embodiment of the present invention can obtain the temperature monitoring results in the cab, and then adjust the throttle opening and the operating speed of the turbocharger, so as to quickly increase the temperature in the vehicle cab and improve the user's comfort.

[0066] Optionally, adjusting the opening of the throttle valve 1 according to the temperature monitoring result, and thus adjusting the operating speed of the turbocharger 3, includes:

[0067] When the temperature inside the cab is within the first temperature range, the opening of the throttle valve 1 is adjusted to the first opening range so that the operating speed of the turbocharger 3 reaches the first speed range;

[0068] When the temperature inside the cab is within the second temperature range, the opening of the throttle valve 1 is adjusted to the second opening range so that the operating speed of the turbocharger 3 reaches the second speed range;

[0069] When the temperature in the cab is in the third temperature range, the opening of the throttle valve 1 is adjusted to the third opening range so that the operating speed of the turbocharger 3 reaches the third speed range; wherein, the temperature in the third temperature range is lower than the temperature in the second temperature range, and the temperature in the second temperature range is lower than the temperature in the first temperature range; the opening value in the third opening range is greater than the opening value in the second opening range, and the opening value in the second opening range is greater than the opening value in the first opening range; the speed value in the third speed range is greater than the speed value in the second speed range, and the speed value in the second speed range is greater than the speed value in the first speed range.

[0070] Controller 5 divides the cab temperature into a first temperature range, a second temperature range, and a third temperature range, respectively, based on the cab temperature, from high to low. Corresponding to the temperature ranges, throttle valve 1 is set to a first opening range, a second opening range, and a third opening range, respectively, based on the opening degree, from small to large. Furthermore, turbocharger 3 is set to a first speed range, a second speed range, and a third speed range, respectively, based on the operating speed, from small to large. After temperature sensor 4 monitors the cab temperature, controller 5 determines the temperature range to which the temperature monitoring result belongs and adjusts throttle valve 1 to the corresponding opening range, thereby adjusting the turbocharger 3's operating speed to the corresponding speed range, generating high-temperature, high-pressure gas and thereby raising the cab temperature.

[0071] The auxiliary heating method proposed in the embodiment of the present invention can determine different throttle openings and different turbocharger operating speeds according to different cab temperatures, thereby achieving precise control of cab temperature and efficient energy utilization.

[0072] Optional, Figure 7 This is another flow chart of the auxiliary heating method provided by the embodiment of the present invention, refer to Figure 7 This embodiment is an optimization based on the above embodiment. Specifically, after adjusting the opening of the throttle valve 1 according to the temperature monitoring result, the following steps are added:

[0073] Get the throttle opening monitoring result.

[0074] Confirm the throttle opening adjustment according to the opening monitoring results.

[0075] like Figure 7 As shown, the method may include the following steps:

[0076] S210: Obtain the temperature monitoring result in the cab.

[0077] S220: Adjust the throttle opening according to the temperature monitoring result, and then adjust the operating speed of the turbocharger.

[0078] S230: Obtain throttle opening monitoring results.

[0079] The throttle position sensor 6 is used in the auxiliary heating system to monitor the opening of the throttle 1 and feed back an electrical signal to the controller 5 .

[0080] S240: Confirm the throttle valve opening adjustment status according to the opening monitoring result.

[0081] The controller 5 can compare the preset opening value with the actual opening value based on the opening monitoring result of the throttle valve 1. If the actual opening value of the throttle valve 1 does not match the preset opening value, the control instruction is corrected in time to ensure that the throttle valve 1 is adjusted as expected, thereby ensuring that the speed of the turbocharger 3 reaches the target speed value.

[0082] Another auxiliary heating method proposed in an embodiment of the present invention confirms the throttle opening adjustment according to the throttle opening monitoring result, thereby avoiding insufficient heating efficiency or energy waste due to inadequate opening adjustment, and improving the system adjustment accuracy and operation reliability.
