Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a method, system and product for preventing sudden entry / exit of low-speed four-wheel drive. Background Art

[0002] At present, more and more vehicles are equipped with high-speed two-wheel drive mode and low-speed four-wheel drive mode to meet the increasing driving needs of drivers. In the prior art, the vehicle is required to enter the neutral state for the entry and exit of the low-speed four-wheel drive mode. When the vehicle is not in the neutral state, the instrument will prompt that the vehicle is not in the neutral state for a certain period of time. If the driver controls the vehicle to enter the neutral state within the certain period of time, then at some point after the certain period of time, the user operates the vehicle to enter the neutral state again, which will cause the vehicle to suddenly enter and exit the low-speed four-wheel drive mode without any prompts, resulting in a slight impact and abnormal noise in the vehicle, affecting the user's driving experience.

[0039] A method for preventing sudden switching in / out of low-speed four-wheel drive is provided in an embodiment of the present application. First, based on a received control request for switching in / out of low-speed four-wheel drive, it is determined whether the vehicle is in neutral; when it is determined that the vehicle is not in neutral, a corresponding prompt message is output and the gear status of the vehicle is continuously monitored to obtain a corresponding monitoring result; when the monitoring result is that the gear status of the vehicle is switched to neutral within a preset response time, the operation of switching in / out of low-speed four-wheel drive corresponding to the control request is responded to; when the monitoring result is that the gear status of the vehicle is not switched to neutral within the preset response time, the vehicle is controlled to no longer respond to the control request and the output of the prompt message is terminated.

At this time, the vehicle will suddenly execute the control operation, and the whole vehicle will suddenly experience slight impact and abnormal noise). BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative labor.

[0042] Figure 2 A schematic diagram of a system for preventing sudden entry / exit of low-speed four-wheel drive is shown as an embodiment of the present application. DETAILED DESCRIPTION

[0043] 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 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.

[0044] refer to Figure 1 , Figure 1 A schematic diagram of a method for preventing sudden entry / exit of low-speed four-wheel drive is shown in an embodiment of the present application.

[0045] like Figure 1 As shown, the present application provides a method for preventing sudden entry / exit of low-speed four-wheel drive, comprising:

[0046] Step S1: Determine whether the vehicle is in neutral according to the received control request of entering / exiting low-speed four-wheel drive.

[0047] In this embodiment, when the driver issues a control request to enter or exit the low-speed four-wheel drive mode through the control panel or remote control in the vehicle, the present application first receives this control request through the electronic control system of the vehicle. Then, the system immediately queries the current gear status of the vehicle to determine whether the vehicle is in the neutral position. The specific determination method can be to determine whether the vehicle is in the neutral position by reading the sensor data of the vehicle gearbox. The sensor can monitor and feedback the current gear information of the vehicle in real time.

[0048] Step S2: When it is determined that the vehicle is not in neutral, a corresponding prompt message is output and the gear status of the vehicle is continuously monitored to obtain a corresponding monitoring result.

[0049] In this embodiment, when it is determined that the vehicle is not currently in neutral, the prompt mechanism is immediately triggered to send a clear prompt message to the driver. The prompt message can be presented through the vehicle's central control display screen, indicator lights on the instrument panel, or sound alarms, and the content of the prompt message is preferably "The vehicle is not currently in neutral, please switch the vehicle to neutral to switch to the low-speed four-wheel drive mode." At the same time, the system begins to continuously monitor the gear status of the vehicle to wait for the driver's response.

[0050] Step S3: When the monitoring result shows that the gear state of the vehicle is switched to neutral within a preset response time, respond to the operation of switching in / out of low-speed four-wheel drive corresponding to the control request.

[0051] In this embodiment, if the monitoring result is that the driver switches the gear state of the vehicle to neutral within the preset response time (for example, 3 seconds or 5 seconds, etc., the specific time can be adjusted according to the vehicle type and the driver's needs), it is considered that the driver has performed the correct operation according to the prompt. At this time, the system will respond to the driver's initial control request to enter / exit the low-speed four-wheel drive, and control the execution of the corresponding operation of entering / exiting the low-speed four-wheel drive mode. During this execution process, the vehicle's electronic control system coordinates the working status of the engine, gearbox and four-wheel drive system to ensure the smoothness and safety of the execution process.

[0052] Step S4: When the monitoring result is that the gear state of the vehicle has not been switched to neutral within the preset response time, the vehicle is controlled to no longer respond to the control request and the output of the prompt information is terminated.

[0053] In this embodiment, if the monitoring result is that the driver has not switched the gear state of the vehicle to neutral within the preset response time (for example, 3 seconds or 5 seconds, etc., the specific time can be adjusted according to the vehicle type and the driver's needs), it is considered that the driver has not performed the correct operation according to the prompt. At this time, after the preset response time is reached, the system will no longer respond to the driver's initial control request to switch in / out of low-speed four-wheel drive, and the control action requested by the initial control request is terminated.

[0054] A method for preventing sudden switching in / out of low-speed four-wheel drive is provided in an embodiment of the present application. First, based on a received control request for switching in / out of low-speed four-wheel drive, it is determined whether the vehicle is in neutral; when it is determined that the vehicle is not in neutral, a corresponding prompt message is output and the gear status of the vehicle is continuously monitored to obtain a corresponding monitoring result; when the monitoring result is that the gear status of the vehicle is switched to neutral within a preset response time, the operation of switching in / out of low-speed four-wheel drive corresponding to the control request is responded to; when the monitoring result is that the gear status of the vehicle is not switched to neutral within the preset response time, the vehicle is controlled to no longer respond to the control request and the output of the prompt message is terminated. Therefore, a method for preventing sudden switching in / out of low-speed four-wheel drive provided in the present application can execute the control operation within a short period of time after the driver requests the vehicle to execute the control operation of switching in / out of the low-speed four-wheel drive mode, or directly stop responding to the control operation, instead of waiting for the vehicle to enter neutral before suddenly executing the control operation, so that the whole vehicle suddenly experiences slight impact and abnormal noise during the switching process, which brings a bad driving experience to the driver (for example, after the driver requests the vehicle to execute the control operation of switching in / out of the low-speed four-wheel drive mode, the vehicle is not in neutral, and the driver does not switch the vehicle to neutral within the prompted time, but after a long period of time, the driver controls the vehicle to switch to neutral due to driving needs. At this time, the vehicle will suddenly execute the control operation, and the whole vehicle will suddenly experience slight impact and abnormal noise).

[0055] In combination with the above embodiments, in one implementation, the present application also provides a method for preventing sudden entry / exit of low-speed four-wheel drive. In the method for preventing sudden entry / exit of low-speed four-wheel drive, step S1 may include:

[0056] Step S11: Output corresponding confirmation prompt information according to the received control request of entering / exiting low-speed four-wheel drive.

[0057] In this embodiment, since the control of the vehicle entering / exiting the low-speed four-wheel drive requires the vehicle to be in neutral, in order to cultivate the novice driver to habitually switch the vehicle to neutral when he wants to initiate a request for the vehicle to enter / exit the low-speed four-wheel drive mode, thereby ensuring the efficiency and smoothness of the switching process, the present application provides another implementation method for step S1, specifically: when the driver issues a control request to enter or exit the low-speed four-wheel drive mode through the control panel or remote control in the vehicle, the present application first receives this control request through the electronic control system of the vehicle. Subsequently, in order to remind the driver to confirm the vehicle status, the system immediately outputs a confirmation prompt message. The confirmation prompt message can be presented by the vehicle's central control display screen, the indicator light on the instrument panel, or the sound alarm, and the content of the confirmation prompt message is preferably "the switching operation requires the vehicle to be in neutral, please confirm whether the vehicle is in neutral", and the purpose of this step is to cultivate the driver's habit of actively checking whether the vehicle is in neutral before switching the mode, and actively switching the vehicle to neutral in advance when it is not in neutral.

[0058] Step S12: determining whether an initiated confirmation instruction is received according to the confirmation prompt information, wherein the confirmation instruction is issued after the driver performs a neutral gear confirmation operation based on the confirmation prompt information.

[0059] In this embodiment, after the confirmation prompt information is output, the system starts to monitor whether the driver has initiated a confirmation instruction based on the confirmation prompt information. The confirmation instruction can be issued by the driver through a button on the control panel, a confirmation option on the touch screen, or a specific key on the remote control. The system monitors in real time whether the driver has initiated a confirmation instruction by reading data from these input devices.

[0060] Step S13: When the confirmation instruction is received within the preset monitoring time, determining whether the vehicle is in neutral.

[0061] In this embodiment, if the result of monitoring whether the driver has initiated a confirmation instruction is that the driver has initiated a confirmation instruction within a preset monitoring time (for example, 3 seconds or 5 seconds, etc., the specific time can be adjusted according to the vehicle type and the driver's needs), it is considered that the driver has confirmed that the vehicle is in neutral. However, in order to avoid the driver accidentally touching or misunderstanding the prompt information, the system will not perform the switching operation immediately. Instead, it will actively confirm the gear status of the vehicle again and determine whether the vehicle is indeed in neutral by reading the gearbox sensor data.

[0062] In this embodiment, the application not only cultivates the driver's relevant habits and improves the driver's safety awareness when switching to low-speed four-wheel drive mode by adding confirmation prompt information and driver confirmation steps, but also ensures the safety of operation through the system's active confirmation mechanism.

[0063] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for preventing sudden entry / exit of low-speed four-wheel drive. In the method for preventing sudden entry / exit of low-speed four-wheel drive, the method further includes: if the confirmation instruction is not received within a preset monitoring time, controlling the vehicle to no longer respond to the control request and ending the output of the confirmation prompt information.

[0064] In this embodiment, during the actual driving process, some drivers may not understand the operational requirements of switching in / out of low-speed four-wheel drive, or fail to respond to the system's confirmation prompt information in time due to negligence, accidental touch, etc. In order to deal with this situation, the present application adds a processing mechanism for unresponsive confirmation prompt information on the basis of the original method to improve the flexibility of the system and user experience. Specifically: when the driver issues a control request to switch in or out of the low-speed four-wheel drive mode through the control panel or remote control in the vehicle, the present application first receives this control request through the electronic control system of the vehicle. Subsequently, in order to remind the driver to confirm the vehicle status, the system immediately outputs a confirmation prompt message. The confirmation prompt message can be presented through the vehicle's central control display screen, the indicator light on the instrument panel, or the sound alarm. The content of the confirmation prompt message is preferably "This switching operation requires the vehicle to be in neutral, please confirm whether the vehicle is in neutral". The purpose of this step is to cultivate the driver's habit of actively checking whether the vehicle is in neutral before switching modes, and actively switching the vehicle to neutral in advance when it is not in neutral.

[0065] In this embodiment, after the confirmation prompt information is output, the system starts to monitor whether the driver has initiated a confirmation instruction based on the confirmation prompt information. The confirmation instruction can be issued by the driver through a button on the control panel, a confirmation option on the touch screen, or a specific key on the remote control. The system monitors in real time whether the driver has initiated a confirmation instruction by reading data from these input devices.

[0066] In this embodiment, if the result of monitoring whether the driver has initiated a confirmation instruction is that no confirmation instruction is detected from the driver within a preset monitoring time (for example, 3 seconds or 5 seconds, etc., the specific time can be adjusted according to the vehicle type and the driver's needs), it is deemed that the driver has not confirmed that the vehicle is in neutral. At this time, the system will ignore the control request for switching in / out of low-speed four-wheel drive previously received and will not perform any switching operation. At the same time, the system will stop outputting the previous confirmation prompt information to avoid unnecessary interference to the driver. This operation helps to improve the user experience and enable the driver to focus on the driving task.

[0067] In this embodiment, the present application further improves the flexibility of the system and the user experience by adding a processing mechanism for unreceived confirmation instructions. When the driver fails to respond to the system's confirmation prompt information in time, the system can automatically ignore the control request to avoid the potential risks caused by misoperation. At the same time, ending the output of the prompt information also helps to reduce the driver's interference and improve driving safety.

[0068] In combination with the above embodiments, in one implementation, the present application embodiment further provides a method for preventing sudden entry / exit of low-speed four-wheel drive. In the method for preventing sudden entry / exit of low-speed four-wheel drive, before step S1, the method further includes steps S01 to S02:

[0069] Step S01: Acquire the driver's driving behavior data.

[0070] In this embodiment, the neutral gear determination implementation method proposed in this application, which introduces "confirmation prompt information" and "confirmation instructions", has certain redundancy. The main purpose of its existence is to cultivate some good operating habits of novice drivers in the process of controlling the switching of entering / exiting the low-speed four-wheel drive mode. For experienced drivers, they generally know that the vehicle needs to be in neutral before entering / exiting the low-speed four-wheel drive mode. Therefore, this neutral gear determination implementation method that introduces "confirmation prompt information" and "confirmation instructions" has certain redundancy, which will make the driving experience for experienced drivers poor. Based on this, the present application adopts different neutral gear determination implementation methods for novice drivers and experienced drivers, respectively, so as to improve the driving experience of experienced drivers and cultivate good operating habits of novice drivers. Specifically: when the vehicle is started or in driving state, the system starts to automatically collect the driver's driving behavior data, which is collected in real time through the vehicle's built-in sensors and control system and stored in the vehicle's electronic control unit (ECU).

[0071] Step S02: Analyze the driving behavior data to determine the type of the driver.

[0072] In this embodiment, the collected driving behavior data is analyzed by a corresponding algorithm to determine the type of driver, which includes a novice driver and a non-novice driver (that is, an experienced driver). According to the analysis results, it is determined whether the driver is a novice driver or a non-novice driver. Among them, the driving behavior data includes two types of behavior data, namely, vehicle driving behavior data and driver driving behavior data; vehicle driving behavior data includes: speed control behavior data, vehicle distance keeping behavior data, merging and overtaking behavior data; driver driving behavior data includes: sitting posture and steering wheel holding behavior data, sight and attention behavior data, and traffic rules compliance behavior data.

[0073] In the present application, in the case where the method further includes steps S01 to S02, when it is determined that the driver is a novice driver, the implementation of step S1 is the implementation of steps S11 to S13.

[0074] In this embodiment, when the system detects that a novice driver is currently driving the vehicle, the implementation method of step S1 is as follows: when the novice driver issues a control request to enter or exit the low-speed four-wheel drive mode through the control panel or remote control in the vehicle, the present application first receives this control request through the electronic control system of the vehicle. Subsequently, in order to remind the novice driver to confirm the vehicle status, the system immediately outputs a confirmation prompt message. The confirmation prompt message can be presented through the vehicle's central control display screen, indicator lights on the instrument panel, or sound alarms. The content of the confirmation prompt message is preferably "This switching operation requires the vehicle to be in neutral, please confirm whether the vehicle is in neutral". The purpose of this step is to cultivate the habit of novice drivers to actively check whether the vehicle is in neutral before switching modes, and actively switch the vehicle to neutral in advance if it is not in neutral.

[0075] In this embodiment, after outputting the confirmation prompt information, the system starts to monitor whether the novice driver has initiated a confirmation instruction based on the prompt information. The confirmation instruction can be issued by the novice driver through a button on the control panel, a confirmation option on the touch screen, or a specific key on the remote control. The system monitors in real time whether the novice driver has initiated a confirmation instruction by reading data from these input devices.

[0076] In this embodiment, if the monitoring result of whether the novice driver has initiated a confirmation instruction is that the novice driver has initiated a confirmation instruction within a preset monitoring time (for example, 3 seconds or 5 seconds, etc., the specific time can be adjusted according to the vehicle type and driver needs), it is considered that the novice driver has confirmed that the vehicle is in neutral. However, in order to prevent the novice driver from accidentally touching or misunderstanding the prompt information, the system will not perform the switching operation immediately. Instead, it will actively confirm the gear status of the vehicle again and determine whether the vehicle is indeed in neutral by reading the gearbox sensor data.

[0077] In the present application, when the method further includes steps S01 to S02, when it is determined that the driver is a novice driver, the implementation method of step S1 is: upon receiving a control request to enter / exit low-speed four-wheel drive, immediately determine whether the vehicle is in neutral.

[0078] In this embodiment, when the system detects that a novice driver is currently driving the vehicle, the implementation method of step S1 is as follows: when the non-novice driver issues a control request to enter or exit the low-speed four-wheel drive mode through the control panel or remote control in the vehicle, the present application first receives this control request through the electronic control system of the vehicle. Subsequently, the system immediately queries the current gear status of the vehicle to determine whether the vehicle is in neutral position. The specific determination method can be to determine whether the vehicle is in neutral by reading the sensor data of the vehicle gearbox. The sensor can monitor and feedback the current gear information of the vehicle in real time.

[0079] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for preventing sudden entry / exit of low-speed four-wheel drive. In the method for preventing sudden entry / exit of low-speed four-wheel drive, the driving behavior data is analyzed to determine the type of the driver, including: determining a first probability that the type of the driver is a novice driver by analyzing the vehicle driving behavior data; determining a second probability that the type of the driver is a novice driver by analyzing the driver's driving behavior data; and determining whether the driver is a novice driver based on the first probability and the second probability.

[0080] In this embodiment, the present application analyzes the behavior data of the category of vehicle driving behavior data and the behavior data of the category of driver driving behavior data respectively. Based on the analysis and processing of the behavior data of the category of vehicle driving behavior data, a first probability that the corresponding driver type is a novice driver is obtained. Based on the analysis and processing of the behavior data of the category of driver driving behavior data, a second probability that the corresponding driver type is a novice driver is obtained. In view of the different relevance of these two types of behavior data to whether the driver is a novice driver, corresponding weights are set respectively. After obtaining the first probability and the second probability, the first probability is multiplied by the weight corresponding to itself, and the second probability is multiplied by the weight corresponding to itself, and the two multiplication results are added again. If the final probability obtained exceeds the set threshold, the driver is determined to be a novice driver, and if it does not exceed, it is determined to be a non-novice driver.

[0081] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for preventing sudden entry / exit of low-speed four-wheel drive. In the method for preventing sudden entry / exit of low-speed four-wheel drive, before step S1, the method includes: after the vehicle is started, determining whether a driver's strategy switching request is received, the strategy switching request is used to indicate that the current vehicle is driven by a novice driver; in the case of receiving the strategy switching request, determining whether the vehicle is in neutral according to the received control request for entry / exit of low-speed four-wheel drive, including: outputting corresponding confirmation prompt information according to the received control request for entry / exit of low-speed four-wheel drive; determining whether an initiated confirmation instruction is received according to the confirmation prompt information, the confirmation instruction is issued by the driver after performing a neutral confirmation operation based on the confirmation prompt information; in the case of receiving the confirmation instruction within a preset monitoring time, determining whether the vehicle is in neutral; in the case of not receiving the strategy switching request, determining whether the vehicle is in neutral according to the received control request for entry / exit of low-speed four-wheel drive, including: in the case of receiving a control request for entry / exit of low-speed four-wheel drive, determining whether the vehicle is in neutral.

[0082] In this embodiment, in addition to passively determining whether the driver is a novice driver through the driver's driving behavior data, the present application also sets a corresponding control button for the user to actively initiate a request to inform the vehicle's control system whether a novice driver is currently driving the vehicle, thereby improving the user experience. Specifically: a special control button is set inside the vehicle, and the button is used to receive the driver's strategy switching request. This button can be located on the vehicle's center console, steering wheel, or other locations that are easily accessible to the driver. The button is clearly marked with a logo, such as "novice mode" or "novice driving", so that the driver can easily identify its purpose. When the vehicle is started, the system starts to monitor the status of the control button. If the driver presses the button, the system will immediately receive a strategy switching request, indicating that the novice driver is driving the vehicle at this time. When the corresponding user presses the control button again, the system will determine that the vehicle is currently driven by a non-novice driver.

[0083] In this embodiment, when it is determined that the current driver is a novice based on the received strategy switching request, the neutral gear determination implementation method introduced with "confirmation prompt information" and "confirmation instruction" proposed in the above application is adopted to determine whether the vehicle is in neutral.
