All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
According to embodiments of the present invention, there is provided a method, apparatus, system and vehicle for controlling a resistive heater, it being noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system, such as a set of computer executable instructions, and that although a logical sequence is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in a different order than that illustrated herein.
Fig. 1 is a flowchart of an alternative control method of a resistance heater according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, a first working state of a vehicle engine and a first environment temperature of an environment where the vehicle is located are obtained.
The first operating state may be understood as an operating state of the engine before the resistive heater starts operating, and the first ambient temperature may be understood as a temperature of an external environment in which the vehicle is located before the resistive heater starts operating.
In an alternative embodiment, the first operating state of the engine may include an on, off, standby, etc. state.
In another alternative embodiment, the first ambient temperature may be obtained by a temperature sensor mounted externally to the vehicle.
Step S104, judging whether to heat the ventilation pipe of the engine or not based on the first working state and the first environment temperature.
It can be understood that after the whole vehicle is electrified, the ventilation pipe of the engine is not heated by default, and whether the temperature in the current ventilation pipe is too low or not needs to be judged according to the working state of the engine and the current environmental temperature, so that whether the ventilation pipe of the engine needs to be heated or not is judged.
Since the temperature inside the engine is affected by the operating state of the engine and the external ambient temperature, it is necessary to determine whether or not the ventilation pipe inside the engine needs to be heated according to the operating state of the engine and the ambient temperature.
In an alternative embodiment, the ventilation pipe of the engine may be in particular a ventilation pipe in a crankcase ventilation system of the engine.
In particular, an engine crankcase ventilation system is understood to mean a system for ventilating the interior of an engine to ensure proper operation of the engine, wherein during operation of the engine, high-pressure combustible gas mixture and combusted gas in the combustion chamber may leak into the crankcase more or less through the gap between the piston assembly and the cylinder, causing blow-by. The components of the blowby gas are unburned fuel gas, water vapor, waste gas and the like, which dilutes engine oil, reduces the service performance of the engine oil and accelerates the oxidation and deterioration of the engine oil. The water vapor condenses in the engine oil to form oil sludge, so that an oil way is blocked, acid gas in the exhaust gas is mixed into a lubricating system, corrosion and accelerated abrasion of engine parts can be caused, and the blowby gas can cause the pressure of a crankcase to be too high to break the sealing of the crankcase, so that the engine oil is lost. Therefore, crankcase ventilation must be performed to prevent excessive crankcase pressure, extend engine oil life, reduce wear and corrosion of parts, and prevent engine oil leakage.
Fig. 2 is a schematic diagram of an engine crankcase ventilation system according to an embodiment of the invention, and as shown in fig. 2, the engine crankcase ventilation system is composed of a crankcase, a positive crankcase ventilation (Positive Crankcase Ventilation, abbreviated as PCV) valve, a check valve, an air cleaner (abbreviated as air filter), a supercharger, a throttle valve, an intake manifold, an oil-gas separator, and the like. When the pressure of the crankcase is low, fresh air is sucked into the crankcase through the check valve 1 by a crankcase air supplementing pipe connected to an air inlet connecting bent pipe; when the pressure of the crankcase is higher, the crankcase ventilation pipe connected to the air inlet connecting bent pipe reintroduces the exhaust gas in the crankcase into the air inlet system and burns off in the cylinder, so that the pressure in the crankcase is balanced within a certain range, meanwhile, the air pollution can be reduced, the fuel economy is improved, the piston blowby gas passes through the PCV valve after entering the oil-gas separator from the crankcase, the heavy-load working condition gas passes through the check valve 2, the supercharger and the throttle valve, and enters the air inlet manifold, and the light-load working condition gas passes through the check valve 3 and enters the air inlet manifold, so that the operation of the crankcase ventilation system is completed.
And step S106, controlling the resistance heater to start to work in response to heating the ventilation pipe, wherein the resistance heater is positioned at the joint of the ventilation pipe and the air inlet pipe of the engine.
Among these, a resistive heater is understood to be a device that converts electrical energy into thermal energy using the principle of joule heating to effect heating of an object.
Specifically, the resistance heater is composed of a resistor, an impedance element and the like, the control module in the resistance heater is generally composed of an electric heating coil, a capacitor and a controller, the control module can control the task of the heating device according to different parameters, and the control module can automatically adjust according to the temperature or the heating time so as to keep the heating device within a preset temperature range.
It will be appreciated that the resistive heater remains in the default off condition at all times and only if it is required to heat the ventilation duct is required to control the operation of the ventilation duct to ensure proper operation of the engine.
Fig. 3 is a schematic view of a location of a resistive heater according to an embodiment of the present invention, and as shown in fig. 3, an engine crankcase ventilation system is composed of a crankcase, a PCV valve, a check valve, an air cleaner (abbreviated as air filter), a supercharger, a throttle valve, an intake manifold, an oil-gas separator, and the like. When the pressure of the crankcase is low, fresh air is sucked into the crankcase through the check valve 1 by a crankcase air supplementing pipe connected to an air inlet connecting bent pipe; when the pressure of the crankcase is higher, the crankcase ventilation pipe connected to the air inlet connecting bent pipe reintroduces the exhaust gas in the crankcase into the air inlet system and burns off in the cylinder, so that the pressure in the crankcase is balanced within a certain range, meanwhile, the air pollution can be reduced, the fuel economy is improved, the piston blowby gas passes through the PCV valve after entering the oil-gas separator from the crankcase, the heavy-load working condition gas passes through the check valve 2, the supercharger and the throttle valve, and enters the air inlet manifold, and the light-load working condition gas passes through the check valve 3 and enters the air inlet manifold, so that the operation of the crankcase ventilation system is completed. The resistance heater is arranged at the joint of the air filtering ventilation pipe and the air inlet pipe of the heavy-load working condition gas.
Through the steps, the first working state of the vehicle engine and the first environmental temperature of the environment where the vehicle is located are obtained, whether the ventilation pipe of the engine is heated or not is judged based on the first working state and the first environmental temperature, if the ventilation pipe of the engine needs to be heated, the resistance heater is controlled to start working, and the fact that the resistance heater is located at the joint of the ventilation pipe and the air inlet pipe of the engine is easy to notice, so that after the resistance heater starts working, the air temperature in the ventilation pipe and the air inlet pipe can be increased, and the phenomenon of ice blockage of a pipeline caused by low temperature is avoided. By the method, whether the ventilation pipe of the engine needs to be heated or not is judged according to the working state of the engine and the ambient temperature, if so, the resistance heater is controlled to start working, the purpose of preventing pipeline ice blockage caused by too low temperature is achieved, the technical effect that the engine can still normally run in low-temperature weather is achieved, and the technical problem of abnormal engine operation caused by pipeline ice blockage in the related art is solved.
Optionally, determining whether to heat a ventilation pipe of the engine based on the first operating state and the first ambient temperature includes: in response to the first working state being a preset state, and the first ambient temperature being less than or equal to a first preset temperature, determining to heat the ventilation pipe; in response to the first operating condition not being a preset condition, or the first ambient temperature being greater than a first preset temperature, it is determined that the ventilation tube is not to be heated.
The preset state may be understood as an operating state of the engine for determining whether to turn on the resistive heater, for example, may be a state in which the engine is running, and the first preset temperature may be a lower external environment temperature of the engine for determining whether to turn on the resistive heater, for example, may be 0 ℃, or other temperatures that may be considered that the current external environment temperature is lower and may affect the normal running of the engine.
It can be understood that when the vehicle is running in an environment with too low an external environment temperature, the warm and humid air flow in the ventilation pipe is liquefied and condensed into frost in the pipeline after being contacted with the cold air in the air inlet pipe, and the frost is continuously accumulated to cause the phenomenon of ice blockage of the curved pipe, so that the exhaust gas of the crankcase is not smooth, the pressure is increased, the engine is abnormal in operation, and the ice particles possibly fall off and strike on the blades of the turbocharger rotating at a high speed to cause serious problems such as damage of the supercharger.
If the ambient temperature is too low, but the engine is not in an operating state, no influence is caused on the operation of the vehicle, so that the ventilation pipe in the engine is not required to be heated.
Optionally, after controlling the resistive heater to start operating, the method further comprises: acquiring a second working state of the engine and a second environment temperature of the environment where the vehicle is located; and judging whether to stop heating the ventilation pipe or not based on the second working state and the second environment temperature.
The second operating state may be understood as an operating state of the engine after the resistive heater starts to operate, and the second ambient temperature may be understood as an ambient temperature outside the engine after the resistive heater starts to operate.
In an alternative embodiment, the second operating state of the engine may include an on, off, standby, etc. state.
In another alternative embodiment, the second ambient temperature may be obtained by a temperature sensor mounted externally to the vehicle.
It can be understood that after the resistance heater starts to work, the running state of the engine and the external environment temperature need to be monitored at any time so as to judge whether the ventilation pipe in the engine needs to be continuously heated, and unnecessary energy waste can be saved under the condition that the normal running of the engine is ensured.
Optionally, based on the second operating state and the second ambient temperature, determining whether to stop heating the ventilation pipe includes: responding to the second working state as a preset state, and determining that the ventilation pipe is continuously heated when the second ambient temperature is smaller than the second preset temperature; and determining to stop heating the ventilation pipe in response to the second operating state being not the preset state or the second ambient temperature being greater than or equal to the second preset temperature.
The second preset temperature may be an external ambient temperature preset in advance for judging whether to continue heating the ventilation pipe in the engine, for example, may be 5 ℃, or other temperatures that may be considered that the current ambient temperature is suitable and will not affect the normal operation of the engine.
It will be appreciated that after the resistive heater is turned on, if the engine is still running and the external ambient temperature is low, normal operation of the engine will still be affected, and therefore it is necessary to continue heating the ventilation pipe in the engine.
If the ambient temperature is low, but the engine is not in a running state, no influence is caused on the running of the vehicle, so that the ventilation pipe in the engine does not need to be heated continuously.
Optionally, in response to heating a vent pipe of the engine, controlling the resistive heater to start operation includes: the electric circuit is controlled to be closed by the engine control system, the resistance heater starts to work, wherein the input end of the electric circuit is connected with a power supply, the output end of the electric circuit is connected with the resistance heater, and the control end of the electric circuit is connected with the engine control system.
The engine control system can be used for controlling devices inside the engine to start working, and in the embodiment of the invention, the engine control system is connected with the resistance heater through a circuit and can be used for controlling the on and off of the resistance heater.
Specifically, the engine control system mainly comprises an electronic control unit, a signal input device and an actuator, wherein the electronic control unit is mainly responsible for providing reference voltage for each sensor, receiving electric signals input by the sensors or other devices, storing, calculating and analyzing the received signals, and then sending instructions to the actuator; the signal input device refers to various sensors and is mainly used for collecting signals required by the control system, converting the signals into electric signals and providing lines for the electronic control unit; the actuator is controlled by the electronic control unit and is mainly used for specifically executing a device with a certain control function.
Fig. 4 is a schematic diagram of a functional interface of a resistive heater according to an embodiment of the present invention, as shown in fig. 4, with one end of the resistive heater grounded and the other end connected to an engine control system.
Optionally, acquiring the first operating state of the vehicle engine and the first ambient temperature of the environment in which the vehicle is located includes: acquiring the current speed of a vehicle and the current environment temperature of the environment where the vehicle is located; the first ambient temperature is determined based on the current vehicle speed and the current ambient temperature.
The current vehicle speed may be understood as the current running speed of the vehicle, and the current ambient temperature may be understood as the temperature of the external environment in which the vehicle is currently located.
In an alternative embodiment, the current speed of the vehicle may be obtained by a speed sensor, and the current ambient temperature of the vehicle may be obtained by an air conditioning temperature sensor provided outside the vehicle.
It can be appreciated that, because the air-conditioning temperature sensor is disposed at the front end of the radiator of the vehicle, when the vehicle is idling, the air-conditioning temperature sensor is affected by the heat radiation of the radiator, so that the data collected by the sensor is not the actual current ambient temperature, and therefore, the collected data needs to be corrected to ensure the authenticity of the data, and the influence on the normal operation of the engine due to data errors is avoided.
Optionally, determining the first ambient temperature based on the current vehicle speed and the current ambient temperature includes: determining that the first ambient temperature is the current ambient temperature of the vehicle in response to the current vehicle speed being greater than the preset vehicle speed; and determining the first environmental temperature as a preset environmental temperature in response to the current vehicle speed being smaller than or equal to a preset vehicle speed, wherein the preset environmental temperature is used for representing the environmental temperature corresponding to the preset vehicle speed.
The preset vehicle speed may be understood as a vehicle running speed preset in advance, at which the vehicle may be considered to be idling, and the preset ambient temperature may be understood as an ambient temperature outside the vehicle corresponding to the preset vehicle speed when the vehicle is at the preset vehicle speed.
In an alternative embodiment, the preset speed may be 15km/h or other values, and the invention does not limit the preset speed, and if the current speed of the vehicle is greater than or equal to 15km/h, the air flow of the vehicle is considered to be more sufficient at this time, so that the current environment temperature can be reflected more accurately, and the measured current environment temperature can be used as the first environment temperature; if the current speed of the vehicle is less than 15km/h, the vehicle can be considered to be in an idle state at the moment and the current environment temperature cannot be accurately reflected, so that the environment temperature measured before the vehicle enters the idle state can be used as the first environment temperature.

The engine control system starts to collect the running state of the engine and the temperature of the outside environment of the vehicle, wherein the ambient temperature is the external ambient temperature corrected by the air conditioner controller, and when the engine is in the running state and the temperature of the outside environment of the vehicle is less than or equal to 0 ℃, the engine control system turns on a circuit to drive the resistance heater to work; if either condition is not met, the circuit is not conducted, and the resistance heater does not work. When the resistance heater works, the engine control system continuously collects the engine running state and the vehicle external environment temperature, and when the engine is not in the running state or any condition that the vehicle external environment temperature is more than or equal to 5 ℃ occurs, the engine control system breaks a circuit and closes the resistance heater. Experiments prove that the embodiment of the invention can effectively avoid the problem of ice blockage of the crankcase ventilation pipe in a low-temperature environment.
