[0002] As the global energy crisis and environmental problems become increasingly serious, the development of new energy vehicles has received widespread attention. Among them, alcohol-hydrogen electric buses, as a new type of clean energy transportation, have the advantages of zero emissions, low noise, and high energy utilization, and have gradually become an important part of urban public transportation. Alcohol-hydrogen electric buses usually use methanol as fuel and charge the power battery through a methanol range extender.

It can provide additional endurance for electric buses when the battery is low. However, the problem of starting a methanol range extender in a low-temperature environment has always been a technical problem in the industry.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The alcohol-hydrogen electric bus is a hybrid bus that combines multiple energy technologies. Its main feature is that it generates electricity through the chemical reaction of methanol and hydrogen to drive the vehicle. This bus has two fuel tanks: one is a traditional gasoline tank and the other is a methanol tank. Among them, the gasoline tank is used to store traditional gasoline as a backup energy source or in specific circumstances to ensure that the vehicle can still operate normally when the supply of methanol or hydrogen is insufficient. The methanol tank is used to store methanol fuel. Methanol is one of the core energy sources of alcohol-hydrogen electric buses. It can be converted into hydrogen through methanol reforming technology and then used for power generation.

[0049] A methanol range extender is a device that converts methanol fuel into electrical energy through a chemical reaction. It can provide additional endurance for electric buses when the battery is low. However, the problem of starting a methanol range extender in a low-temperature environment has always been a technical problem in the industry. Due to the high freezing point of methanol, when the ambient temperature drops, the fluidity of methanol will drop significantly, resulting in insufficient fuel supply inside the methanol range extender, which in turn causes difficulty in starting.

[0050] The existing low-temperature cold start solution mainly relies on adding pretreatment of methanol fuel. However, adding pretreatment steps will increase the complexity and cost of the system, and may require the modification of the existing vehicle structure. Secondly, the existing system lacks intelligent control strategies and cannot automatically select the most appropriate start mode according to actual environmental conditions. Therefore, a methanol engine cold start solution is urgently needed to effectively solve the start-up problem of the methanol range extender in low-temperature environments.

[0051] The methanol range extender startup method, device, electronic device and vehicle provided in the present application obtain the fuel tank parameters and temperature parameters of the vehicle; wherein the fuel tank parameters include the gasoline tank level value, and the temperature parameters include the engine coolant temperature; if the gasoline tank level value and the coolant temperature both meet the preset conditions, a first instruction is sent to the methanol range extender, and the first instruction is used to instruct the gasoline supply system to deliver gasoline fuel to the methanol range extender; if the gasoline tank level value and the coolant temperature do not meet the preset conditions, a second instruction is sent to the methanol range extender, and the second instruction is used to instruct the heating system to heat the engine coolant to the first preset temperature, so that the methanol supply system delivers methanol fuel to the methanol range extender. The present application adopts two modes of gasoline supply startup and heating startup, which can realize efficient and reliable startup of the methanol range extender in a low temperature environment, and solves the problem that the traditional methanol range extender is difficult to start at low temperatures.

[0052] Exemplary Implementation Environment

[0053] Please refer to Figure 1 , Figure 1 It is a schematic diagram of an implementation environment involved in the present invention.

[0054] like Figure 1 As shown, the implementation environment involves vehicles. Among them, the vehicle can be equipped with a vehicle control unit (VCU), which can collect key information for starting the methanol range extender system, such as ambient temperature, engine coolant temperature, gasoline level, methanol level, PTC system heating status, and methanol range extender system operating status, through CAN messages. After receiving the above information, the VCU processes it and determines the start mode of the methanol range extender. The start modes include gasoline-assisted start mode and methanol start mode after heating by the heating system.

[0055] Exemplary Methods

[0056] Figure 2 This is a flowchart of the methanol range extender startup method provided in the embodiment of the present application; please refer to Figure 2 In an exemplary embodiment, a methanol range extender starting method is provided, and the method may include:

[0057] S220: Obtaining fuel tank parameters and temperature parameters of the vehicle; the fuel tank parameters include the fuel tank liquid level value; the temperature parameters include the engine coolant temperature;

[0058] In practical applications, the vehicle can measure the fuel tank level value through sensors, such as pressure level sensors, magnetostrictive level sensors, optical level sensors, etc., and transmit it to the VCU for processing through the CAN bus. The vehicle can determine the engine coolant temperature through temperature sensors, such as thermistor temperature sensors, etc., and transmit it to the VCU for processing through the CAN bus.

[0059] S240: If the gasoline tank liquid level value and the coolant temperature both meet the preset conditions, sending a first instruction to the methanol range extender, the first instruction is used to instruct the gasoline supply system to deliver gasoline fuel to the methanol range extender;

[0060] In the embodiment of the present application, gasoline is stored in the gasoline tank. When the gasoline tank liquid level and coolant temperature meet the preset conditions, the VCU issues a start command to switch the fuel supply from methanol to gasoline. At this time, the gasoline enters the combustion chamber of the methanol range extender through the fuel pump and the injector.

[0061] S260: If the gasoline tank liquid level value and the coolant temperature do not meet the preset conditions, send a second instruction to the methanol range extender. The second instruction is used to instruct the heating system to heat the engine coolant to a first preset temperature, and then the methanol supply system delivers methanol fuel to the methanol range extender.

[0062] When both the gasoline tank liquid level value and the coolant temperature do not meet the preset conditions, the gasoline tank liquid level value may meet the preset liquid level value, but the coolant temperature does not meet the preset temperature value, that is, the coolant needs to be heated by the heating system to increase the temperature of the engine coolant so that the methanol supply system can deliver methanol fuel to the methanol range extender.

[0063] In actual application, the VCU sends a second instruction to enable the heating system to heat the coolant. After the temperature of the coolant reaches the first preset temperature, the methanol range extender system feeds back the heating end flag to the VCU. After the VCU receives the heating end flag of the methanol range extender system, it triggers the vehicle controller to send a methanol mode start instruction.

[0064] The heating system in the embodiment of the present application can heat the methanol fuel by installing an electric preheater in the air intake system or the fuel supply system. For example, a grid-type electric preheater is used to preheat the methanol fuel. In a low temperature environment, the electric preheater can heat the fuel to a certain temperature, improve the atomization and evaporation performance of the fuel, and thus improve the cold start performance of the engine.

[0065] In practical applications, the heating system may adopt a positive temperature coefficient (PTC) heating system, which improves fuel fluidity and enhances vehicle safety and reliability.

[0066] In the embodiment of the present application, the methanol tank stores methanol. When the VCU issues a start command, the methanol fuel enters the combustion chamber of the methanol range extender through the fuel pump and the injector.

[0067] The methanol range extender starting method provided in the embodiment of the present application realizes the use of gasoline to assist in starting the methanol range extender in a low temperature environment, or starts the methanol range extender after heating with a heating system, by checking whether the vehicle's gasoline tank liquid level value and coolant meet preset conditions, thereby ensuring the reliability of low-temperature cold starts.

[0068] In an optional embodiment, the preset conditions include whether the fuel tank liquid level value is higher than the preset liquid level value, whether the coolant temperature is higher than the second preset temperature value, and whether the coolant temperature is higher than the third preset temperature value; the second preset temperature value is less than the third preset temperature value;

[0069] The fuel tank level and coolant temperature meet the preset conditions, including:

[0070] The fuel tank liquid level value is higher than the preset liquid level value and the coolant temperature is higher than the second preset temperature value; or, the fuel tank liquid level value is higher than the preset liquid level value and the coolant temperature is higher than the third preset temperature value.

[0071] When the vehicle is started at low temperature, it can first be determined whether the liquid level value of the gasoline tank is higher than the preset liquid level value. The preset liquid level value can be determined based on the historical data or experimental data of the vehicle start. When the liquid level value of the gasoline tank is higher than the preset liquid level value, it means that the vehicle can be started with gasoline assistance. Secondly, it is determined whether the coolant temperature is higher than the second preset temperature value and whether the coolant temperature is higher than the third preset temperature value. The second preset temperature value can correspond to the minimum temperature for starting with gasoline, and the third preset temperature value can correspond to the minimum temperature for starting with methanol. In actual applications, the second preset temperature is lower than the third preset temperature value.

[0072] In actual applications, when the gasoline tank liquid level value is higher than the preset liquid level value and the coolant temperature is higher than the second preset temperature value or the third preset temperature value, the VCU sends a first instruction to instruct the gasoline supply system to deliver gasoline fuel to the methanol range extender to start the methanol range extender.

[0073] When the gasoline level value is higher than the preset level value and the coolant temperature is higher than the second preset temperature value or the third preset temperature value, a first instruction is sent to start the methanol range extender with gasoline, thereby improving the economy of the vehicle.

[0074] In an optional embodiment, the fuel tank liquid level value and the coolant temperature do not meet the preset conditions, including: the fuel tank liquid level value is higher than the preset liquid level value, and the coolant temperature is lower than the second preset temperature value; or, the fuel tank liquid level value is lower than the preset liquid level value, and the coolant temperature is lower than the third preset temperature value.

[0075] When the gasoline tank liquid level value is higher than the preset liquid level value, it is judged that the coolant temperature is less than the second preset temperature value; or when the gasoline tank liquid level value is lower than the preset liquid level value, but at the same time the coolant temperature is less than the third preset temperature value, gasoline-assisted starting cannot be used at this time. At this time, a second instruction is sent to increase the coolant temperature to the preset temperature through the heating system, and then use the methanol supply system to deliver methanol fuel to the methanol range extender.

[0076] By using a heating system to heat the coolant and then using methanol to start the vehicle when the fuel tank liquid level value is higher than the preset liquid level value and judging that the coolant temperature is lower than the second preset temperature value; or when the fuel tank liquid level value is lower than the preset liquid level value but at the same time the coolant temperature is lower than the third preset temperature value, the stability of vehicle starting in low temperature environments can be ensured.

[0077] In an optional embodiment, the method further includes:

[0078] Get the ambient temperature;

[0079] Determine the heating time based on the fuel tank level value, ambient temperature and coolant temperature;

[0080] The heating system heats the engine coolant for a heating time so that the coolant temperature reaches a first preset temperature.

[0081] In practical applications, the heating time can be determined by a preset mapping relationship. The preset mapping relationship may include a mapping relationship between the gasoline level L, the ambient temperature E, the engine coolant temperature T and the heating time. For example, when the gasoline tank level is less than the preset level, the ambient temperature is less than -30°C, and the coolant temperature is less than -25°C, the heating time may be 15 minutes; when the gasoline tank level is greater than the preset level, the ambient temperature is less than -30°C, and the coolant temperature is less than -25°C, the heating time may be 5 minutes.

[0082] In an optional embodiment, after sending the first instruction to the methanol range extender, the method further includes:

[0083] Get the engine speed of the methanol range extender;

[0084] If the speed is less than the preset speed, a second instruction is sent to the methanol range extender.

[0085] When gasoline is used as fuel to start the methanol range extender, if the engine speed of the methanol range extender is less than the preset speed, the heating system is switched to heat the coolant to avoid repeated start failures after the gasoline-assisted start attempt fails, causing damage to the methanol range extender system. The preset speed can be the engine idle speed.

[0086] In an optional embodiment, after the methanol supply system delivers methanol fuel to the methanol range extender, the method further includes:

[0087] Get the engine speed of the methanol range extender;

[0088] If the speed is less than the preset speed, a second instruction is sent to the methanol range extender.

[0089] When methanol is used as fuel to start the methanol range extender, if the engine speed of the methanol range extender is less than the preset speed, the heating system is switched to heat the coolant to avoid problems such as repeated start failures after failed methanol start attempts, causing damage to the methanol range extender system. The preset speed can be the engine idle speed.

[0090] In an optional embodiment, the method further includes:

[0091] Get the number of times the second instruction is sent;

[0092] If the number reaches a preset threshold, a third instruction is sent to the vehicle controller, and the third instruction is used to indicate that the methanol range extender has failed to start.

[0093] In practical applications, the number of times the second instruction is sent can be used to determine whether the vehicle has a fault, so that the startup mode can be exited in time when the vehicle has a fault. The preset number threshold can be 2 times, that is, after the heating system is heated twice, the third instruction is sent to the VCU to exit the startup mode.
