[0042] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0043] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.
[0044] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0045] The embodiments of the present application provide a control method for a vehicle self-rescue mode in extreme scenarios. Refer to Figure 1 As shown, the method mainly includes the following steps:
[0046] Step S110, when it is detected that a vehicle system fails, perform fault handling according to a preset fault emergency handling strategy.
[0047] In one implementation, the vehicle system may include, for example, a vehicle high-voltage system, a vehicle drive system, a vehicle interaction system, etc.
[0048] The failures of the above vehicle systems can be mainly roughly classified into three cases: the vehicle loses its driving ability (high voltage is disconnected or the system ready light is turned off), the vehicle's driving ability is limited (such as speed limit or limp mode), and the vehicle's driving function is not limited.
[0049] In this embodiment, for emergency self-rescue in extreme scenarios, the vehicle system failure referred to may be a vehicle failure caused by any failure of a system related to controlling driving, and is not specifically limited to the failure of a specific component or structure.
[0050] In one implementation, the preset fault emergency handling strategy is a fault routine handling strategy pre-configured for the vehicle. For example, when a high-voltage interlock or bipolar insulation fault occurs, the pre-configured fault routine handling strategy may be to disconnect the high-voltage signal of the vehicle according to the preset situation; for another example, when the shift module fails, the pre-configured fault routine handling strategy may be to make the vehicle stop and lose its driving ability without cutting off the high-voltage circuit; and when the vehicle cuts off the high-voltage signal due to low battery power, the pre-configured fault routine handling strategy may be that when the battery power reaches the lower limit in the scenario where the engine cannot start, that is, stop discharging.
[0051] Step S120, determine whether the conditions for triggering the vehicle self-rescue mode are met according to the fault handling result of the preset fault emergency handling strategy and the current vehicle scenario.
[0052] The fault handling result of the preset fault emergency handling strategy is also the result after the above-mentioned preset fault conventional handling strategy is processed. For example, cutting off the vehicle's high-voltage signal, disabling the vehicle's driving ability, stopping discharging, etc.
[0053] It can be understood that the vehicle self-rescue mode referred to in the embodiments of the present application refers to the following situation: when a vehicle fails, there will still be certain safety risks after being processed by the preset fault emergency handling strategy. At this time, the vehicle self-rescue mode performs self-rescue operations as a hidden underlying function, and there may be some risks, but it will be relatively safer than the result after being processed by the preset fault emergency handling strategy.
[0054] In one implementation, it is determined whether the conditions for triggering the vehicle self-rescue mode are met according to the fault handling result of the preset fault emergency handling strategy and the current vehicle scenario. In specific implementation, the following steps may be included:
[0055] Step 1.1), if the fault handling result of the preset fault emergency handling strategy is the loss of the vehicle's driving function, the vehicle performs a self-check to determine whether the vehicle has the function of restarting and driving again. The fault handling result of the preset fault emergency handling strategy being the loss of the vehicle's driving function can be that when a vehicle fails, the vehicle stops driving; whether the vehicle has the function of restarting and driving again refers to whether the vehicle hardware actually has the function of driving. For example, when a high-voltage interlock occurs, the vehicle cuts off the high voltage, and at this time the vehicle can no longer drive, but the vehicle's drive system, tires, engine, etc. have not failed, and at this time the vehicle has the function of restarting and driving again.
[0056] Step 1.2), obtain the vehicle's surrounding scene through the vehicle image acquisition device, and determine whether the vehicle's surrounding scene meets the preset extreme scene. The current vehicle scenario can be obtained through the image acquisition device on the vehicle, and it is judged whether the current vehicle scenario is some relatively harsh environments, such as remote mountainous areas, desert areas, muddy areas, mountain winding roads, etc. Preferably, the current weather conditions can be comprehensively judged. For example, in heavy rain weather on a relatively desolate mountain road, if the vehicle breaks down and cannot drive, it may pose a more serious safety threat. At this time, it can be judged that the conditions for triggering the vehicle self-rescue mode are met.
[0057] Step 1.3), if the vehicle has the function of restarting and driving again and the current scene meets the preset extreme scene, it is determined that the conditions for triggering the vehicle self-rescue mode are met.
[0058] Step S130, if satisfied, enter the vehicle self-rescue mode, and respond to the vehicle self-rescue operation initiated for the vehicle fault type in the vehicle self-rescue mode to restore the vehicle's emergency drive function; wherein, the vehicle fault type includes vehicle high-voltage system faults and vehicle drive interaction faults.
[0059] In one embodiment, when it is determined that the conditions for triggering the vehicle self-rescue mode are met, the vehicle self-rescue mode is entered through user triggering. Optionally, to ensure the successful entry into the vehicle self-rescue mode, the vehicle self-rescue operation may include triggering through the central control instrument or triggering through relevant combination keys.
[0060] When it is detected that the user triggers to enter the vehicle self-rescue mode, the corresponding vehicle self-rescue is performed according to the fault handling method corresponding to the corresponding vehicle fault type.
[0061] The vehicle self-rescue mode control method provided by the embodiments of the present application enters the vehicle self-rescue mode when corresponding conditions are met, and restores the vehicle emergency drive function by responding to the self-rescue operation, which can alleviate the safety hazards caused by vehicle failures in extreme scenarios, improve the vehicle fault handling ability in extreme scenarios, and improve the vehicle's self-rescue ability on the premise of ensuring the safety of vehicle personnel to meet the requirements of some vehicle functions in special scenarios.
[0062] For ease of understanding, the vehicle self-rescue mode control method provided by the embodiments of the present application is described in detail below.
[0063] In one embodiment, before restoring the vehicle emergency drive function in response to the vehicle self-rescue operation initiated for the vehicle fault type in the vehicle self-rescue mode, the vehicle self-rescue mode can be entered through user triggering. In specific implementation, it may include the following steps:
[0064] Step 2.1), determine whether the vehicle central control instrument function is normal;
[0065] Step 2.2), if it is normal, initiate the vehicle self-rescue operation by triggering the vehicle central control instrument function;
[0066] Step 2.3), if it is not normal, initiate the vehicle self-rescue operation by inputting through the preset combination keys.
[0067] In practical applications, the central control instrument can be preferably used for corresponding triggering. For example, when the vehicle shift module fails, the user can trigger the vehicle self-rescue mode by triggering the gear module on the visual interface of the central control instrument and manually inputting the gear signal (P / R / N / D).
[0068] However, considering that the central control instrument function may be lost after a possible failure, in order to avoid being unable to enter the vehicle self-rescue mode, it can also be initiated through a preset combination key after the central control instrument function is abnormal. Still taking the failure of the vehicle shift module as an example, when the central control instrument function is abnormal, the combination key of braking + pulling up the Electrical Park Brake (EPB) button + pressing the cruise INC button can be used to trigger the entry into the R gear. In practical applications, the combination method of this combination key can be adjusted adaptively. This is only an example here and is not specifically limited.
[0069] The above introduces that the vehicle failure types can include vehicle high-voltage system failures and vehicle drive interaction failures. Vehicle high-voltage system failures can include high-voltage interlock, bipolar insulation failure, and high-voltage disconnection due to low battery power. Vehicle drive interaction failures can include shift module failures. The following elaborates on the failure types corresponding to the two systems.
[0070] (1) Vehicle high-voltage system failure - high-voltage interlock:
[0071] When a high-voltage interlock occurs, in response to the vehicle self-rescue operation initiated for the high-voltage interlock in the vehicle self-rescue mode, the maximum driving power of the vehicle is restricted, and the vehicle emergency driving function is restored with a preset low-range driving power.
[0072] (2) Vehicle high-voltage system failure - bipolar insulation failure:
[0073] When a bipolar insulation failure occurs, in response to the vehicle self-rescue operation initiated for the bipolar insulation failure in the vehicle self-rescue mode, if the door signal is on, the high-voltage signal is cut off;
[0074] if the door signal is off, the maximum driving power of the vehicle is restricted, and the vehicle emergency driving function is restored with a preset low-range driving power.
[0075] (3) Vehicle high-voltage system failure - high-voltage disconnection due to low battery power:
[0076] When a high-voltage disconnection due to low battery power occurs, in response to the vehicle self-rescue operation initiated for the high-voltage disconnection due to low battery power in the vehicle self-rescue mode, the lower limit of the discharge depth is reduced, and the emergency discharge mode is entered.
[0077] (4) Vehicle drive interaction failure - shift module failure:
[0078] When a shift module failure occurs, in response to the gear signal input by the visual interface operation initiated for the shift module failure in the vehicle self-rescue mode, the driving power is restricted;
[0079] Or,
[0080] In response to the gear signal input by the preset combination key for the failure of the shift module in the vehicle self-rescue mode, enter the emergency driving mode indicated by the gear signal.
[0081] In one example, the following table provides a way for the vehicle to self-rescue corresponding to the above 4 types of failures:
[0082]
[0083] The preset fault emergency handling strategy in the above table is the conventional fault handling method preset for the vehicle, and this embodiment does not make specific limiting descriptions. For the combination key method in the vehicle self-rescue mode, the methods in the above table are only examples, and in actual applications, the corresponding keys can be added, deleted, or replaced.
[0084] Figure 2 A flowchart of an overall solution processing is shown. When the vehicle has a fault and loses its driving function, the vehicle control follows the normal control logic to implement post-fault processing (that is, the fault is processed according to the preset fault emergency handling strategy as described above), and then it is judged whether the driver triggers the self-rescue mode. If so, the fault is identified as a specific fault type (this specific fault type corresponds to the above 4 types of faults), and then it is judged whether the central control instrument is normal. If the central control instrument is normal, the driver inputs key signals such as the gear through the central control instrument. If the central control instrument is abnormal, the driver inputs the driving requirements through the combination key, and then the vehicle restores the driving function.
[0085] The above method of the present application can be applied to SUV vehicles that feature a cross-country function. In a harsh environment, if a vehicle breaks down in a remote mountainous area or desert area and loses its driving ability, it is very likely that the vehicle problem will bring difficulties to the accompanying personnel and even affect the safety of the personnel. Therefore, on the premise of ensuring the safety of the vehicle personnel, the driver conducts safety identification and actively triggers the self-rescue mode of the vehicle to improve the self-rescue ability of the vehicle to meet the needs of some functions of the vehicle in special scenarios, so as to realize some driving requirements of the vehicle by the driver under emergency conditions.
[0086] Compared with the conventional control scheme, the failure of a specific component will directly cause the vehicle to lose its driving function (such as the failure of the shift module). In the vehicle self-rescue mode involved in the application, the vehicle can complete the substitution through other signals to meet the vehicle driving requirements in an emergency scenario. Under the self-rescue mode trigger condition, some driving functions in the fault state are restored to ensure that the vehicle does not lose its driving function due to a specific component, and the vehicle function requirements of the driver in special scenarios can be solved.
[0087] Based on the above method embodiment, the embodiment of the present application also provides a vehicle self-rescue mode control system for extreme scenarios. See Figure 3As shown, the system mainly includes the following parts:
[0088] An emergency handling module 310, which is used to perform fault handling according to a preset fault emergency handling strategy when a vehicle system failure is detected;

[0092] Judge whether the vehicle central control instrument function is normal;
