Description

Technical Field

[0001] The present invention relates to the field of heating, and in particular to a method and device for heating a vehicle, a storage medium, and a processor. Background Art

[0002] Currently, all electric buses on the market that use single-cooling air conditioning all use PTC heaters to heat the interior of the vehicle. However, vehicles using PTC heaters for heating are unable to achieve temperature control. When the driver turns on the heater, the PTC heater starts heating, and when the heater is turned off, the heating stops. Drivers generally turn on the heater and turn it off when they leave work. During this period, even if the temperature inside the vehicle meets the heating requirements, the heater will continue to operate, resulting in energy waste. Generally, a PTC heater is 2KW, and buses over 10m long need to be equipped with 4-6 heaters, which means that 8-12 kWh of electricity is consumed per hour. Coupled with the significant degradation of power batteries in winter, the driving range is severely shortened, which is prone to user complaints.

[0003] In addition, the PTC heaters currently on the market do not have the PTC waste heat consumption function. If the heater is turned on for a long time, the PTC temperature will be relatively high. If the heater switch is suddenly turned off, the waste heat on the PTC has not dissipated yet, and the heater fan has stopped working. The waste heat is not effectively utilized, and there will be certain safety hazards, which will shorten the life of the PTC.

[0004] Currently, no effective solution has been proposed to the above-mentioned problems existing in the related technologies. Summary of the Invention

[0024] For ease of description, some nouns or terms involved in the embodiments of the present invention are explained below:

[0025] PTC heating sheet: also called PTC heater, it is composed of PTC ceramic heating element and aluminum tube. It has the advantages of low thermal resistance and high heat exchange efficiency. It is a constant temperature and energy-saving electric heater.

[0026] According to an embodiment of the present invention, a method for heating a vehicle is provided.

[0027] Figure 1 FIG. 1 is a flow chart of a method for heating a vehicle according to an embodiment of the present invention. Figure 1 As shown, the invention includes the following steps:

[0028] Step S101: Acquire the interior temperature of the target vehicle.

[0029] Step S102 : determining whether the temperature difference between the vehicle interior temperature and the first preset temperature reaches a temperature alarm value based on the temperature difference between the vehicle interior temperature and the first preset temperature.

[0030] Step S103: When the temperature difference reaches the temperature alarm value, power supply to some or all of the PTC heating sheets in the target vehicle is stopped.

[0031] Specifically, an embodiment of the present application provides a heating system, which is generally used in buses and consists of a PTC heating control panel (including a heating switch group, a delay module, and a temperature controller module), a control circuit (including a control line and a relay), a heating unit (including a PTC heating sheet, a high-voltage contactor, a heating fan, a temperature switch, a buzzer, etc.), and an in-vehicle temperature sensor. A control circuit is responsible for controlling at least one heating unit, and a heating unit contains a group of PTC heating sheets and a heating fan corresponding to a group of PTC heating sheets.

[0032] The heating system provided in the present application can control the operation of the PTC heating plate according to the temperature difference between the obtained vehicle interior temperature and the first preset temperature, thereby regulating the temperature inside the vehicle.

[0033] By reasonably setting the first preset temperature and the temperature alarm value, reasonable temperature control of the PTC heating plate in the car is achieved, achieving the purpose of reducing energy consumption, increasing driving range, and improving the safety performance of the entire vehicle.

[0034] Optionally, after obtaining the interior temperature of the target vehicle, the method further includes: when the interior temperature of the vehicle is greater than or equal to a first preset temperature, controlling all PTC heating sheets and all heater fans not to turn on, wherein one heater fan corresponds to a group of PTC heating sheets; when the interior temperature of the vehicle is lower than the first preset temperature, controlling all or part of the PTC heating sheets and all or part of the heater fans to turn on.

[0035] Specifically, different models and sizes of buses are equipped with different numbers of heaters. Each heater contains a set of PTC heating plates and a heater blower. The heater blower is used to blow the heat generated by the PTC heating plates to other places in the bus to improve the efficiency of dissipating heat into the bus.

[0036] In a method for heating a vehicle provided by the present application, the actual temperature in the vehicle is detected by a temperature sensor arranged in the vehicle. When the actual temperature in the vehicle is greater than a preset temperature, there is no need to control the PTC heating plate and the heater fan in the vehicle to start working. For example, if the actual temperature in the vehicle is greater than or equal to 25°C, it means that the temperature in the vehicle is suitable and there is no need to start the heater to heat the vehicle. At this time, the PTC heating plate and the heater fan are controlled not to work.

[0037] On the contrary, if the temperature inside the car is lower than 25℃, it means that the temperature inside the car is too low to provide a comfortable riding environment for the passengers. The PTC heating plates and heater fans need to be turned on to heat the car. At this time, the number of PTC heating plates and heater fans to be turned on can be selected according to the density of the passengers. If there are more passengers in the PTC car and the density is higher, fewer PTC heating plates and heater fans can be turned on. If there are fewer passengers in the car, a larger number of PTC heating plates and heater fans can be turned on first.

[0038] In an optional embodiment, when the actual temperature PV in the vehicle is lower than the set temperature (first preset temperature) SV, turn on any one of the switches in the heater switch group on the PTC heater control panel or turn on all of them, the heater contactor in the high-voltage box of the whole vehicle is energized, and the high voltage of the whole vehicle starts to supply power to each heater unit. At the same time, the fan and PTC in each heater work normally to achieve heating.

[0039] It should be noted that when the temperature is lower than the first preset temperature, the number of groups of PTC heating elements and heater fans to be turned on can be set specifically according to different situations.

[0040] It should also be noted that the driver sets the desired interior temperature (SV) and various alarm levels (AL) via the PTC heater control panel (internal thermostat module). The alarm level is defined as the difference between the actual temperature (PV) detected by the interior temperature sensor and the set temperature (SV). The set temperature (SV) can be set between 17°C and 30°C. The default alarm levels are: AL1 (Level 1) at -2°C, AL2 (Level 2) at 0°C, and AL3 (Level 3) at 3°C.

[0041] Optionally, the method also includes: when the temperature difference reaches a first alarm value, controlling the high-voltage contactor in part of the control circuit to disconnect to stop heating part of the PTC heating plates in the target vehicle, and controlling the heater fans corresponding to the PTC heating plates to turn off after a preset time, wherein multiple groups of PTC heating plates are arranged in the target vehicle, each heater fan corresponds to a group of PTC heating plates, and one control circuit corresponds to controlling a preset number of PTC heating plate groups and a preset number of heater fans.

[0042] Specifically, in the heating circuit in the car, usually, a control circuit is used to control at least two heaters. When the difference between the temperature in the car and the first preset temperature reaches a first warning value, it means that the real-time temperature in the car is close to the required temperature set in the car (that is, the first preset temperature). From the perspective of energy saving, when the actual temperature in the car is close to the required temperature, some of the PTC heating plate groups in the car are turned off, but the heater fans corresponding to the closed PTC heating plate groups do not immediately follow the corresponding PTC heating plate groups to turn off. Instead, the delay module of the control circuit controls the heater fans corresponding to some of the closed PTC heating plate groups to delay for a preset period of time and then turn off, so as to achieve the purpose of blowing the residual heat on the closed PTC heating plates into the car through the heater fans. Through the above method, the energy-saving effect is achieved, the safety factor of the PTC heating plates is improved, and the life of the PTC heating plates is extended.

[0043] As mentioned above, in an optional embodiment, when the difference between the actual temperature PV and the set temperature SV in the vehicle reaches -2°C, Figure 2 As shown in the control circuit shown in , the first-level alarm value AL1 contact in the control circuit is closed and maintained, the high-voltage contactor in the heater unit 1 (a control circuit is responsible for controlling at least one heater unit) is disconnected, and heating stops. At the same time, the delay module in the PTC heater fan controller stops supplying power to the heater unit 1 after a delay of 15 seconds; during the delay period, the heater fan continues to work, effectively utilizing the residual heat on the PTC, and at the same time, the temperature on the PTC can be reduced to normal, improving safety performance; after the delay time is up, the heater fan also stops working; the significance of this alarm value is to reasonably control the power consumption of the entire vehicle. When the actual temperature is close to the set temperature, one group of heaters can be automatically turned off to reduce energy consumption, among which, Figure 2 This is a schematic diagram of a control circuit controlling two heaters.

[0044] It should be noted that Figure 2 The figure shows a schematic diagram of a heating subsystem controlling two heating units.

[0045] Optionally, the method also includes: when the temperature difference reaches a second alarm value, controlling the high-voltage contactor in part of the control circuit to disconnect to stop heating part of the PTC heating plates in the target vehicle, and controlling the heater fans corresponding to part of the PTC heating plates to turn off after a preset time.

[0046] Specifically, when the actual interior temperature (PV) equals the set temperature (SV), the temperature difference reaches the second alarm value. The secondary alarm value (AL2) contact in the control circuit closes and remains closed, disconnecting the high-voltage contactor in heater unit 2 and halting heating. Simultaneously, the delay module in the PTC heater controller stops powering heater unit 2 after a 15-second delay. During this delay, the heater blower continues to operate, effectively utilizing residual heat from the PTC and reducing the PTC temperature to normal, enhancing safety. After the delay expires, the heater blower also stops. This alarm value is designed to reduce vehicle energy consumption. When the actual temperature reaches the set temperature, the heater automatically shuts off, reducing energy consumption and increasing driving range.

[0047] It should also be noted that the preset time length for the delayed shutdown of the heater fan is preferably 15S. In different situations, it can be set according to different models of PTC heating sheets.

[0048] Optionally, the method also includes: when the temperature difference reaches a third alarm value, controlling the disconnection of high-voltage contactors in all control circuits to stop heating all PTC heating plates in the target vehicle, and controlling the heater fans corresponding to all PTC heating plates to turn off after a preset time, wherein multiple groups of PTC heating plates are arranged in the target vehicle, each heater fan corresponds to a group of PTC heating plates, and one control circuit corresponds to controlling a preset number of PTC heating plate groups and a preset number of heater fans.

[0049] Specifically, when the difference between the actual interior temperature (PV) and the setpoint temperature (SV) reaches 3°C (the third warning value), indicating the interior temperature is higher than the desired temperature, the third-level alarm (AL3) contact opens and remains active. The heater contactor in the vehicle's high-voltage box disconnects, shutting off power to each heater unit. Each heater fan then shuts down after a 15-second delay to dissipate excess heat from the PTC. This alarm setting ensures that if the first two heater alarms fail, the high-voltage power supply to the heater unit can be forcibly cut off, improving control reliability.

[0050] It should be noted that when the actual temperature PV in the vehicle is lower than the set temperature SV again, the above logic cycle will be followed.

[0051] Optionally, the method also includes: when it is detected that the temperature of any group of PTC heating plates in the target vehicle is greater than or equal to a second preset temperature, controlling the normally open temperature switch in the control circuit corresponding to the PTC heating plate to close to trigger an alarm; when it is detected that the temperature of any group of PTC heating plates in the target vehicle is greater than or equal to a third preset temperature, controlling the normally closed temperature switch in the control circuit corresponding to the PTC heating plate to disconnect to stop heating the PTC heating plate, wherein the second preset temperature is lower than the third preset temperature.

[0052] Specifically, when the temperature of the PTC heating element in any heater reaches 95°C or higher, the normally open temperature switch in the corresponding heater closes and a buzzer sounds to alert the driver. When the PTC temperature in any heater reaches 130°C or higher, the normally closed temperature switch in the corresponding heater opens, disconnecting the high-voltage contactor and stopping heating.

[0053] Optionally, the method also includes: when a target instruction is detected, stopping heating for all PTC heating plates in the target vehicle, and controlling the heater fans corresponding to all PTC heating plates to turn off after a preset time, wherein the target instruction is used to turn off the heating equipment in the target vehicle.

[0054] Specifically, during normal operation of the heater unit, when the driver normally turns off the heater switch, the high-voltage contactor in each heater is first disconnected to stop heating. After a delay of 15 seconds, the heater fan is disconnected to ensure that the PTC residual heat is dissipated and safety hazards are eliminated. The preset instruction is the instruction to turn off the heater.

[0055] It should be noted that the heater units in the car can be increased or decreased according to the length of the car and divided into two or more groups for cross-control.

[0056] An embodiment of the present invention provides a method for heating an interior of a vehicle, which obtains the interior temperature of a target vehicle; determines whether the temperature difference reaches a temperature alarm value based on the temperature difference between the interior temperature and a first preset temperature; and stops supplying power to some or all of the PTC heating sheets in the target vehicle when the temperature difference reaches the temperature alarm value. This solves the technical problem in the related art of using PTC heating sheets for heating on electric buses but being unable to temperature-control the PTC heating sheets, which shortens the service life of the PTC heating sheets, thereby achieving the effect of extending the service life of the PTC heating sheets.

[0057] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
