Description

Technical Field

[0001] The present invention relates to the technical field of seat heating, and in particular to an automatic control method and system for seat heating in an ECO mode. Background Art

[0002] At present, the problem of low-temperature endurance of new energy vehicles is more prominent. One of the reasons is that low-temperature heating consumes a lot of electricity. Therefore, many new energy models in the industry are equipped with ECO mode for the air-conditioning system to reduce the heating energy consumption of the air-conditioning system. ECO mode is a synthesis of Ecology, Conservation and Optimization, representing the economic driving mode of the vehicle. ECO mode achieves energy saving by adjusting the working parameters of the engine and transmission, and controlling the energy consumption of vehicle systems such as air conditioning. However, ECO mode is usually achieved by reducing the power of electrical components such as compressors, PTCs, and blowers, which has an adverse effect on passenger comfort. From the perspective of energy transfer, seat heating is in direct contact with passengers, and is more efficient in heating passengers than the air-conditioning system. Therefore, how the vehicle air-conditioning system can automatically control seat heating in ECO mode to improve passenger comfort is an urgent problem to be solved. Summary of the invention

DETAILED DESCRIPTION

[0047] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0048] Example 1

[0049] Figure 1The invention shows an automatic control method for seat heating in ECO mode. The automatic control method for seat heating in ECO mode is applicable to new energy electric vehicles, and includes the following steps S10-S40 when the vehicle ECO mode and the air conditioning system heating are turned on at the same time.

[0050] First, let's introduce some basic knowledge about the vehicle. Before the vehicle is powered on, all system components are not working, the air conditioning system is off, and the ECO mode is not on. After powering on, the air conditioning system will be in cooling, heating, dehumidification and other modes according to the status of components such as the A / C switch and the temperature setting knob. The ECO mode will also be on and off according to the status of the ECON button. In short, the status of the air conditioning system and the ECO mode can be manually controlled by the passengers, and the air conditioning controller 1 can accurately obtain whether the air conditioning system is in heating mode. Therefore, there are four combinations of the on and off status of the air conditioning system heating and the ECO mode passengers.

[0051] ① The ECO mode is turned off and the air conditioning system heating is turned off. At this time, the passengers have no intention to reduce energy consumption and no demand for heating, so there is no need to automatically control the seat heating.

[0052] ② When the ECO mode is turned on, the air conditioning system heating is turned off, which means that the passengers are willing to reduce energy consumption but have no demand for heating, so the seat heating coordination will not be automatically turned on.

[0053] ③The ECO mode is turned off and the air conditioning system heating is turned on, which means that the passengers want heating at this time, but have no intention of reducing energy consumption, so the seat heating will not be turned on automatically.

[0054] In addition, the air conditioning system's heating works normally, and the working method is as follows: the air conditioning controller 1 calculates the air conditioning target air outlet temperature as the control target based on the input data from each sensor and the air conditioning panel 13, and controls the working state of the air conditioning output components to make the air conditioning system's air outlet temperature reach the target air outlet temperature, and the passenger compartment temperature is close to the air conditioning system's set temperature value on the control panel.

[0055] ④ECO mode is turned on, and the air conditioning system is turned on, indicating that the passengers have a heating demand and are willing to reduce the energy consumption of the system. It may be necessary to automatically control the seat heating to turn on for auxiliary heating to improve comfort. At this time, the air conditioning system works as follows: the air conditioning system calculates the target air outlet temperature in the air conditioning ECO mode based on the input data of each sensor and the air conditioning panel 13. Compared with the target air outlet temperature in normal operation, it is closer to the external ambient temperature. In this mode, the air conditioning system uses the target air outlet temperature in the ECO mode as the control target to make the air outlet temperature of the air conditioning system reach the target air outlet temperature in the ECO mode. At this time, the working state of each output component of the air conditioning system is adjusted to a certain extent compared with the original state. The power of the blower, compressor, and PTC is reduced, and the internal and external circulation ratio of the damper, the ratio of hot and cold mixed air, and the opening of the expansion valve are adjusted to achieve the effect of reducing the energy consumption of the air conditioning system; at this time, the comfort of the passenger compartment may be reduced.

[0056] Step S10: Determine whether the seat heating device 26 has been manually controlled in the current power-on cycle of the vehicle. If so, the method ends and the seat heating device 26 is not automatically controlled. Otherwise, other steps of the method continue to be executed. The current power-on cycle refers to the time from the power-on moment of the vehicle to the current moment. In the current power-on cycle, if the occupant has the intention to autonomously operate the seat heating, the seat heating does not need to be automatically controlled to avoid control duplication and conflict.

[0057] In some embodiments, determining whether the seat heating device 26 has been manually controlled during the current power-on cycle of the vehicle includes:

[0058] If the state of the manual control component 21 of the seat heating device 26 has changed during the current power-on cycle of the vehicle, it is determined that the seat heating device 26 has been manually controlled during the current power-on cycle of the vehicle; otherwise, it is determined that the seat heating device 26 has not been manually controlled during the current power-on cycle of the vehicle.

[0059] The manual control component 21 is usually a button or a knob. A manual operation seat heating flag signal can be set in the seat controller 2: SHMFlag, with an initial value of 0, indicating that in the current power-on cycle, the occupant has not manually operated the seat heating. After the seat heating switch receives the occupant's operation command, SHMFlag = 1, and it will not change before the vehicle is powered off, until the vehicle is powered off and then powered on again, the initial value is 0. In this way, in the current power-on cycle of the vehicle, the state of the manual control component 21 of the seat heating device 26 has changed, corresponding to different SHMFlag values.

[0060] ①SHMFlag=1, indicating that during this power-on cycle, the occupant has the intention to operate the seat heating independently, and the system determines that the seat heating will not be automatically adjusted. The seat heating is executed according to the driver's manual operation.

[0061] ②SHMFlag=0, indicating that during this power-on cycle, the occupant has no intention to operate the seat heating autonomously. However, according to the air-conditioning system input, the driver needs to reduce air-conditioning energy consumption and may want to heat the seat. The system determines that a seat heating device 26 with higher heating efficiency may be needed for heat compensation.

[0062] Step S20: Determine whether the seat heating device 26 is in the off position, if yes, continue to execute other steps of the method, if no, end the method and do not automatically control the seat heating device 26. This serves as a reconfirmation to prevent the seat heating from being manually turned on before power is turned on.

[0063] Step S30: Determine the current cooperative gear position of the seat heating device 26 according to the current external temperature of the passenger compartment, the internal temperature of the passenger compartment and the set temperature value of the air-conditioning system.

[0064] In certain embodiments, determining the current cooperative gear position of the seat heating device 26 according to the current external temperature of the passenger compartment, the internal temperature of the passenger compartment and the set temperature value of the air conditioning system includes the following steps a1 and a2.

[0065] Step a1: Calculate the absolute value of the difference between the current temperature inside the passenger compartment of the vehicle and the set temperature value of the air conditioning system;

[0066] Step a2: according to the absolute value of the difference between the current temperature inside the passenger compartment of the vehicle and the set temperature value of the air conditioning system, and the current temperature outside the passenger compartment of the vehicle, the gear table is consulted to obtain the current coordinated gear of the seat heating device 26;

[0067] The gear table includes the absolute value of the difference between the current temperature inside the passenger compartment of the vehicle and the set temperature value of the air-conditioning system, and the preset correspondence between the current temperature outside the passenger compartment of the vehicle and the coordinated gear of the seat heating device 26.

[0068] Set the seat heating coordination gear: αSH, the initial value is 0, the air conditioning controller 1 calculates, taking the three-speed seat heating as an example (the seat heating temperature from low to high is 0, 1, 2, 3, and 0 is off), the preset corresponding relationship is:

[0069] When |T set -T in |≥10℃ and T out <0℃ or 5℃≤|T set -T in |<10℃ and T out <

[0070] At -5°C, the seat heating device 26 coordination gear is gear 3;

[0071] When |T set -T in|≥10℃ and 0℃≤T out <10℃、5℃≤|T set -T in |<10℃ and -5℃≤T out <0℃ or |T set -T in |<5℃ and T out When the temperature is less than -5°C, the seat heating device 26 cooperates in the 2nd gear;

[0072] When |T set -T in |≥10℃ and 10℃≤T out <15℃、5℃≤|T set -T in |<10℃ and 0℃≤T out <10℃ or |T set -T in |<5℃ and -5℃≤T out When the temperature is less than 0°C, the seat heating device 26 cooperates in the gear 1;

[0073] When |T set -T in |≥10℃ and 15℃≤T out 、5℃≤|T set -T in |<10℃ and 10℃≤T out or T set -T in |<5℃ and 0℃≤T out When the seat heating device 26 cooperates with the gear position 0;

[0074] Among them, T set Set the temperature value for the vehicle's current air conditioning system, T in is the current temperature inside the vehicle's passenger compartment, T out is the current external temperature of the vehicle's passenger compartment, that is, the preset corresponding relationship is as shown in the following Table 1.

[0075] Table 1 Gear table

[0076]

[0077] Step S40: Control the seat heating device 26 to be in the current cooperative gear position.

[0078] According to the seat heating coordination gear calculated in step S30, the air conditioning controller 1 sends a seat heating request signal to the seat controller 2 through the vehicle bus; after receiving the signal, the seat controller 2 sends a corresponding gear instruction to the seat heating device 26, and the seat heating is performed according to the corresponding gear.

[0079] Finally, when the vehicle ECO mode and the air-conditioning system heating are turned on at the same time, if the automatic control is turned on, that is, through determination and judgment, it finally goes to step S40 to control the seat heating device 26 to be in the current cooperative gear. It is also necessary to consider when to end this automatic control gear state in the future. Therefore, the method also includes: after the vehicle ECO mode and the air-conditioning system heating are turned on at the same time, continuously obtain the on and off status of the vehicle ECO mode and the air-conditioning system heating, and whether the seat heating device 26 has been manually controlled, and turn off the seat heating device 26 when the vehicle ECO mode is turned off and / or the vehicle air-conditioning system heating is turned off. When the seat heating device 26 has been manually operated, control the seat heating device 26 according to the manual operation control signal.

[0080] During use, when the air conditioner is running, the air conditioner controller 1 calculates the target air outlet temperature of the air conditioner based on the sensor data and the input of the air conditioner panel 13. After the occupant turns on the ECO mode, the target air outlet temperature of the air conditioner is adjusted, and the execution components are adjusted to achieve the purpose of reducing the heating energy consumption of the vehicle. After the vehicle air conditioner enters the ECO mode, it is determined whether to enter the seat heating cooperative mode. If the determination fails, the seat heating will not be automatically turned on. If the determination succeeds, the seat heating cooperative mode is entered, and then the air conditioner controller 1 calculates the automatic gear position of the seat cooperative heating according to the set temperature, indoor temperature, and outdoor temperature, and sends a corresponding request to the seat controller 2. After receiving the instruction, the seat heating automatically adjusts to the corresponding gear (including the off gear).

[0081] It should be noted that the above step numbers are only for the convenience of description and do not constitute a limitation on the execution order of the steps.
