DETAILED DESCRIPTION

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] In the description of the present invention, it should be understood that the directions or positional relationships indicated, such as up, down, front, back, left, right, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the meaning of "several" is one or more, the meaning of "many" is more than two, greater than, less than, exceeding, etc. are understood to exclude the number itself, and above, below, within, etc. are understood to include the number itself. If there is a description of the first and the second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0021] It is understandable that hybrid vehicles have two driving modes: fuel-driven and electric-driven. When the vehicle speed is low, the power motor is used for driving, and when the vehicle speed is high, the engine is used for driving. Therefore, there is a procedure to start the engine during the vehicle's driving. When the engine fails to start, if it is caused by a fault, the cause of the fault can be confirmed through the fault code, fault light, etc., and the engine management system prohibits the engine from starting again.

[0022] If it is not caused by a malfunction, the more common reason is lack of fuel. Therefore, in the relevant technology, it will be determined whether the remaining fuel level is lower than the preset alarm threshold. When the remaining fuel level is higher than the preset alarm threshold, the vehicle is controlled to travel normally, and the engine is started normally when a request to start the engine is received again; when the remaining fuel level is lower than the preset alarm threshold, the engine management system prohibits the engine from starting again, and the vehicle is driven to limp by the power motor.

[0023] However, the preset alarm threshold of the vehicle's fuel level is anchored to the fuel level required for the vehicle to travel to the nearest gas station, not the fuel level required to start the engine; when the fuel consumption reaches the preset alarm threshold, the remaining fuel level is often greater than the fuel level required to start the engine. The failure to start the engine may be due to slight carbon deposits on the fuel injector, etc. The engine can be successfully started again. The related technology directly prohibits the engine from starting when the remaining fuel level is enough to start the engine, and the vehicle is driven by the power motor to limp, which will greatly reduce the vehicle's performance and user satisfaction.

[0024] The embodiment of the present invention provides a method for processing an engine start failure, which can fully utilize the remaining fuel to start the engine, thereby facilitating full utilization of vehicle performance.

[0025] refer to Figures 1 to 5 The engine start failure processing method according to an embodiment of the present invention is described, which is applied to a vehicle that can be equipped with a cruise function. The fault diagnosis processing method is described below by taking a specific example.

[0026] Reference Figure 1 As shown, the engine start failure processing method is applied to a hybrid vehicle, including but not limited to the following steps: Step S100, obtaining remaining fuel information and a first preset value of the fuel level, the first preset value being less than a preset alarm threshold for alarming insufficient fuel level; Step S110, determining whether the engine fails to start; Step S200, when the engine fails to start, determining whether there is a starting failure of the engine; Step S300, when there is no engine startup failure, judging whether the remaining fuel level is greater than a first preset value according to the remaining fuel level information; Step S400: When the remaining fuel volume is greater than a first preset value, the vehicle is controlled to travel normally.

[0027] The preset alarm threshold is used to alarm for insufficient fuel when the vehicle is running normally, so as to remind the driver that he needs to go to the gas station to refuel. The first preset value is the engine starting fuel threshold, and the first preset value is used to determine whether the remaining fuel can meet the engine starting. In step S400, when the remaining fuel is greater than the first preset value, the vehicle is controlled to run normally, that is, the vehicle continues to be driven by the power motor, and the engine is started normally when a request to start the engine is received again. By applying the above-mentioned engine start failure processing method, when the cause of the start failure is not a fault and the remaining fuel is lower than the preset alarm threshold, the present invention still controls the engine to be able to start again in some cases, that is, the remaining fuel is greater than the first preset value, instead of completely prohibiting the engine from starting, so that the remaining fuel can be fully utilized, which is conducive to giving full play to the vehicle performance.

[0028] In some embodiments of the present invention, Figure 2 As shown, the engine start failure processing method also includes the following steps: Step S500, judging whether the remaining fuel level is greater than a preset alarm threshold value according to the remaining fuel level information; Step S510, when the remaining fuel amount is greater than a first preset value and not greater than a preset alarm threshold, a first type of prompt is sent to the driver; Step S520: When the remaining fuel amount is less than or equal to a first preset value, a second type of prompt different from the first type of prompt is sent to the driver.

[0029] Step S530, when the remaining fuel level is greater than the preset alarm threshold, the vehicle is controlled to travel normally, and no prompt about the remaining fuel level is sent to the driver.

[0030] When the remaining fuel level is greater than the preset alarm threshold, it indicates that the fuel level is sufficient and the vehicle can be controlled to run normally without prompting the driver to avoid interfering with the driver's driving. When the remaining fuel level is not greater than the preset alarm threshold, a prompt is required. The preset alarm threshold can be set to 10 liters, so that the driver has enough fuel to drive to a nearby gas station after receiving the prompt.

[0031] Among them, when the remaining fuel is not greater than the preset alarm threshold, when the remaining fuel is greater than the first preset value, it indicates that the remaining fuel can still start the engine normally, and when the remaining fuel is less than or equal to the first preset value, the remaining fuel is likely to affect the start of the engine. The degree of influence of the two on the vehicle performance is significantly different. Therefore, the present embodiment sets two different fuel situation prompts according to whether the remaining fuel is greater than the first preset value to convey more accurate information to the driver. The driver can accurately judge the remaining fuel situation according to the received first-type prompt or second-type prompt, which is conducive to the driver to make accurate driving route planning; the first preset value can be set to 5 liters, and the first-type prompt is sent to the driver when the remaining fuel is greater than the first preset value. The first-type prompt can be a text prompt to the driver: "The fuel is insufficient, please refuel as soon as possible, and control the vehicle to drive normally", of course, the first-type prompt can also be a sound prompt or a fault light prompt; when the remaining fuel is less than or equal to the first preset value, the second-type prompt is sent to the driver, and the second-type prompt can be a text prompt to the driver: "The fuel is low, please refuel immediately, otherwise it will affect the engine start", of course, the second-type prompt can also be a sound prompt or a fault light prompt.

[0032] In some embodiments of the present invention, the engine start failure processing method further includes the following steps: Step S210, when there is an engine starting failure, the vehicle is controlled to operate in pure electric limp mode, and a fault prompt is sent to the driver.

[0033] When there is an engine start failure, if you insist on trying to start the engine, it may cause the failure to expand. Therefore, this embodiment controls the vehicle to limp in pure electric mode when the engine starts. Pure electric limp means limp in electric drive mode, with the power motor driving the vehicle to limp, and starting the engine is prohibited, so that the vehicle can still be safely driven to a maintenance point for repair. Among them, the types of engine start failures include engine system failure, motor system failure, battery system failure, vehicle controller failure, communication failure, etc. Each failure is accompanied by a different system fault light. The way to send a fault prompt to the driver can be to light up the fault light corresponding to the type of fault.

[0034] In some embodiments of the present invention, Figure 3 As shown, the engine start failure processing method also includes the following steps: Step S600, determining whether an engine start request is received; Step S610, when the remaining fuel amount is less than or equal to the first preset value and an engine start request is received, starting processing is performed on the engine; Step S900, determining whether the engine startup process is successful; Step S910: When the result of starting the engine is not a successful start, the vehicle is controlled to be in pure electric limp mode and the engine is prohibited from starting.

[0035] It is understandable that, due to the accuracy problem of the signal for detecting the remaining fuel level, and the engine operating conditions of each vehicle are different, the engine will not completely fail to start when the remaining fuel level is less than or equal to the first preset value. Considering that the engine may still start successfully when the remaining fuel level is less than or equal to the first preset value, when this embodiment receives an engine start request, it will perform a start process on the engine to try to start the engine; if the result of the start process on the engine is a successful start, the engine can be used to drive the vehicle, which is beneficial to improving driving performance; if the result of the start process on the engine is a start failure, indicating that the remaining fuel level is no longer able to start the engine, the engine management system prohibits the engine from starting to reduce the loss of battery power, and controls the vehicle to limp along in pure electric mode, so that the vehicle can still safely drive to a maintenance point for repair.

[0036] In some embodiments of the present invention, the above step S910 further includes: Step S911, sending a third type of prompt to the driver.

[0037] It is understandable that in the related art, the vehicle only has a fault light corresponding to the preset alarm threshold. When the vehicle fails to start the engine due to insufficient remaining fuel, since there is no corresponding fault light and the vehicle can still be driven by the power motor, it is difficult for the user to determine whether it is caused by insufficient fuel. When the user goes to the repair shop for repair, it is found that it is not a fault but only insufficient fuel, which greatly increases the cost of use and reduces the user experience. In this embodiment, when the result of executing the attempt to start step is not a successful start, the vehicle is controlled to be in pure electric limp mode, and the engine is prohibited from starting, and a third type of prompt is sent to the driver to remind the driver of the remaining fuel and the inability to start the engine; wherein the third type of prompt can be a text prompt to the driver: "The fuel level is extremely low, please refuel immediately, the engine fails to start", of course, the third type of prompt can also be a sound prompt or a fault light prompt; the first type of prompt and the second type of prompt are different from the third type of prompt, so that the information conveyed to the driver is more accurate.

[0038] In some embodiments of the present invention, the engine start failure processing method further includes the following steps: Step S700, determining whether the engine can inject fuel normally; Step S730, when the engine can inject fuel normally and the result of executing the start process on the engine is that the start is successful, the vehicle is controlled to run normally; When the present embodiment performs the starting process on the engine, the engine management system detects whether the engine can inject fuel normally. If the engine can inject fuel normally, it indicates that once the engine is started successfully, the engine can operate normally. Therefore, in step S730, when the engine can inject fuel normally and the result of the starting process on the engine is a successful start, the vehicle is controlled to run normally.

[0039] In some embodiments of the present invention, the engine start failure processing method further includes the following steps: Step S740, when the engine cannot inject fuel normally and the result of starting the engine is that the start is successful, the vehicle is controlled to limp to the maximum extent.

[0040] If the engine cannot inject fuel normally, it means that even if the engine is started successfully, the engine may stall at any time. Based on this consideration, in step S740, when the engine cannot inject fuel normally and the result of the engine start processing is a successful start, the vehicle is controlled to limp along to the maximum extent. The maximum limp along means limp along in a hybrid drive mode, that is, the vehicle is controlled to maximize the use of the remaining fuel and power, and the engine and the power motor are controlled to work together to drive with limited power output for as long as possible to ensure that the vehicle can drive to the repair shop.

[0041] In some embodiments of the present invention, Figure 4 As shown, the step of starting the engine in step S610 specifically includes: Step S710, when the engine can inject fuel normally, repeatedly control the engine to start until the engine starts successfully or the number of starts reaches a preset number threshold; Step S711, when the engine is started successfully, it is determined that the result of executing the start process on the engine is that the start is successful; Step S712: When the number of starts reaches a preset number threshold, it is determined that the result of executing the start processing on the engine is not a successful start.

[0042] It is understandable that when the remaining fuel is insufficient, the engine may need to be ignited multiple times before it can be successfully started; if the engine can inject fuel normally, it indicates that the engine is in good working condition and is likely to be successfully started. Therefore, the engine is allowed to try to start multiple times to make full use of the remaining fuel. In step S710, the preset number threshold can be set to four, that is, when the engine is not successfully started for the fourth time, it is determined that the result of executing the start process on the engine is not a successful start.

[0043] In some embodiments of the present invention, Figure 5 As shown, the step of starting the engine in step S610 specifically includes: Step S720, when the engine cannot inject fuel normally, control the engine to start, and determine whether the engine starts successfully; Step S721, when the engine is started successfully, it is determined that the result of executing the start process on the engine is that the start is successful; Step S722: When the engine is not started successfully, it is determined that the result of executing the start processing on the engine is not a successful start.

[0044] If the engine cannot inject fuel normally, it indicates that the engine is in poor working condition and the possibility of successful starting is small. Each attempt to start consumes battery power. Based on this consideration, the engine is only allowed to start once. Depending on whether the engine can inject fuel normally, the engine is started with different starting rules to make full use of the remaining fuel and power.

[0045] The engine start failure processing method of the present invention can implement the following operation process: The vehicle control unit (HCU) determines whether there is an engine start-related fault through the working status and fault status feedback from controllers such as the engine management system (EMS), battery management system (BMS), and motor control unit (MCU). If so, the corresponding fault light will be turned on and the fault code will be recorded according to the specific cause of the fault, and the vehicle will be controlled to limp along in pure electric mode.

[0046] If there is no engine start-related fault, the vehicle controller obtains the remaining fuel information. When the vehicle controller identifies that the remaining fuel is no more than 10 liters, it prompts the driver that the fuel is insufficient and asks him to refuel as soon as possible. Other functions are controlled by the whole vehicle. When the vehicle controller identifies that the remaining fuel is no more than 5 liters, it prompts the driver that the fuel is low and asks him to refuel immediately, otherwise it will affect the engine starting.

[0047] At the same time, when the vehicle controller recognizes that the remaining fuel is not more than 5 liters and the vehicle has an engine start request, it will perform different controls according to the feedback from the engine management system on whether the fuel injection status can be normal. When the engine management system feedbacks that the fuel injection can be normal, the vehicle controller controls the engine to start. If the engine starts successfully, the vehicle drives normally. If the engine starts unsuccessfully, it continues to try to control the engine to start. When the engine fails to start after more than three attempts, it is determined that the engine cannot start due to insufficient fuel, then the engine is prohibited from starting, the pure electric limp is controlled, and the driver is prompted that the fuel level is extremely low, please refuel immediately, and the engine starts unsuccessfully. When the remaining fuel is so low that it affects the normal fuel injection of the engine, the vehicle controller attempts to control the engine to start. If the engine starts successfully, the vehicle limps to the maximum extent. If the engine starts unsuccessfully, it is directly determined that the engine cannot start due to insufficient fuel, then the engine is prohibited from starting, the pure electric limp is controlled, and the driver is prompted that the fuel level is extremely low, please refuel immediately, and the engine starts unsuccessfully. In the above process, if the user refuels in time according to the prompts, the normal control function will be restored when the remaining fuel level is greater than 5 liters.

[0048] The engine start failure processing method is easy to identify whether the engine start failure is caused by a fault or insufficient fuel. If it is caused by a fault, the maintenance personnel can quickly locate the fault and guide the maintenance through the fault light and fault code. For the start failure caused by insufficient fuel, the user can also clarify what to do according to the text prompts of different levels. In addition, the processing method tries different times to start the engine according to different situations, which increases the possibility of normal driving.

[0049] The embodiment of the present application also provides an engine start failure processing device, such as Figure 6As shown, it includes an engine start failure identification module 050, an engine start failure processing module 060, a fault storage module 070 and a user prompt module 080. The engine start failure identification module 050 is mainly responsible for identifying the failure of the engine start function, including two categories of failure caused by fault conditions and failure caused by insufficient fuel. The engine start failure processing module 060 mainly performs corresponding processing strategies according to the cause category identified by the engine start failure identification module 050. If it is caused by a fault, pure electric limp control is directly performed, and the fault storage module 070 is called to store the fault code, and the user prompt module 080 is called to perform the fault light and fault text prompt. If it is caused by insufficient fuel, the corresponding processing strategy is performed according to the remaining fuel, the engine injection status and the vehicle engine start request, and the user prompt module is called to give the user a corresponding prompt.

[0050] The embodiment of the present application also provides a vehicle, the vehicle includes a memory, a processor, and a program stored in the memory and executable on the processor, and when the program is executed by the processor, any of the engine start failure processing methods provided in the embodiment of the present application is implemented.
