Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to an all-terrain driving mode switching method and system. Background Art

[0002] The popularity of driving modes is due to the high development of electronic control technology. Driving modes use electronic control hardware and various sensors to adjust and intervene in hardware according to the set operating logic and program mode, thereby creating a different driving experience.

[0003] In order to adapt to the requirements of driving freely on various complex terrains, more and more off-road vehicles have begun to adopt all-terrain driving modes. All-terrain driving modes cover vehicle performance settings under various terrains, ensuring that the vehicle can drive on both flat roads and extreme off-road conditions such as swamps, grasslands, wading, and rocks. The more terrains that can be adapted, the more driving modes are required. This ensures a good driving experience and off-road performance, but also brings a series of problems. Therefore, when using a switch to switch driving modes, vehicles with all-terrain driving modes need to make multiple selections before switching to the target driving mode. For example, most current models use a button or knob to switch between multiple driving modes. The driver needs to carefully confirm whether the switch is accurate during operation, and the operation process is relatively complicated and has many steps, which consumes more time and energy, resulting in low switching efficiency, and increases the driver's operating intensity, affecting driving safety; there is also a way to set a control switch for each driving mode, which has problems such as limited layout space and complex operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an all-terrain driving mode switching method and system. In a vehicle with an all-terrain driving mode, the driving mode switching control logic is reasonably set so that the driver can switch the driving mode simply and efficiently.

[0005] In order to solve the above technical problems, the present invention provides an all-terrain driving mode switching method, comprising the following steps:

[0006] When it is necessary to control the vehicle to enter the first driving mode, the first control unit is operated to: if the current driving mode of the vehicle does not belong to the first driving mode, the vehicle is switched to the first default driving mode in sequence according to the setting order of each driving mode in the first driving mode; if the current driving mode of the vehicle belongs to the first driving mode, the vehicle is switched to the first driving mode in sequence according to the current driving mode in sequence according to the setting order of each driving mode in the first driving mode;

[0007] When it is necessary to control the vehicle to enter the second driving mode, the second control unit is operated to: if the current driving mode of the vehicle does not belong to the second driving mode, the vehicle switches accordingly according to the second default driving mode and in the order in which the driving modes in the second driving mode are set; if the current driving mode of the vehicle belongs to the second driving mode, the vehicle switches accordingly according to the current driving mode and in the order in which the driving modes in the second driving mode are set.

[0008] Among them, the vehicle's driving mode is divided into a first driving mode and a second driving mode according to the applicable terrain characteristics. The first driving mode has multiple driving modes suitable for road terrain, and the first default driving mode belongs to the first driving mode. The second driving mode has multiple driving modes suitable for off-road terrain, and the second default driving mode belongs to the second driving mode.

[0009] In the above-mentioned all-terrain driving mode switching system, according to the terrain characteristics corresponding to each driving mode, the all-terrain driving mode is divided into two categories suitable for highway and off-road. The driving modes are classified by controlling and adjusting through two control units, so that when the driver switches the driving mode according to the actual road conditions, he first chooses between the two categories. Since the terrain characteristics corresponding to the two categories are quite different, it is not necessary to consider much to quickly locate and select the first control unit or the second control unit, and then switch to the appropriate driving mode type through different operation control actions within each category, so that the driver can switch the driving mode in a clear and orderly manner without having to select one by one from the complicated all-terrain driving modes, effectively reducing the driver's switching consideration time and operation steps, improving the switching efficiency, and the vehicle can quickly and accurately switch to the driving mode suitable for the current terrain, improving the driver's driving experience. In addition, when it is necessary to switch between the two categories, the corresponding control unit can be directly operated and controlled without stopping the current mode. The control logic is efficient and the operation steps are further simplified.

[0010] As an improvement of the all-terrain driving mode switching method of the present invention, it also includes:

[0011] When it is necessary to control the vehicle to enter the intelligent selection mode, the third control unit is operated to automatically select and switch the vehicle to a driving mode that conforms to the actual road condition information.

[0012] By introducing the intelligent selection mode, the vehicle can intelligently and automatically select and switch the best driving mode during driving, reducing the driver's control actions and static force spent on mode switching, and can also extend the service life of the vehicle, reduce fuel consumption and improve economy. In addition, by adding a third control unit as a control switch for the intelligent selection mode, it forms three distinct driving mode categories with the first control unit and the second control unit, which has little impact on the driver's mode switching efficiency; and because the third control unit automatically puts the vehicle in one of the first driving mode or the second driving mode, it is organically integrated with the control logic of the first control unit and the second control unit. When manually switching between the three control units, the vehicle's driving state control logic is simplified, improving the switching efficiency.

[0013] Furthermore, in the intelligent selection mode, the vehicle automatically selects and switches to a driving mode that conforms to the actual road condition information, including the following steps:

[0014] Obtain actual road condition information when the vehicle is driving;

[0015] Determining an optimal driving mode that matches the actual road condition information;

[0016] The current driving mode of the vehicle is switched to the optimal driving mode.

[0017] As another improvement of the all-terrain driving mode switching method of the present invention, the first control unit is a knob switch or a push-pull switch, and the setting order of each driving mode in the first type of driving mode includes: arranging each driving mode of the first type of driving mode in a first order to form a first forward circulation order and a first reverse circulation order opposite to the first forward circulation order. The first forward circulation order and the first reverse circulation order correspond to the operation actions of the knob switch or the push-pull switch in two different directions, respectively, so that there are two ways of forward operation and reverse operation to reach a certain driving mode, which can be selected preferably, so as to realize flexible control of the first control unit and save operation time.

[0018] Furthermore, the first type of driving modes includes a comfort mode, an economy mode, a sports mode and a personalized mode, the first default driving mode is the comfort mode, and the setting order of each driving mode in the first type of driving modes includes:

[0019] Arranged in sequence: comfort mode, economy mode, sport mode, personal mode; or arranged in sequence: comfort mode, personal mode, sport mode, economy mode.

[0020] By operating and controlling the first control unit, you can achieve a cyclic switching of comfort mode → economy mode → sports mode → personalized mode → comfort mode or comfort mode → personalized mode → sports mode → economy mode → comfort mode, integrating the same type of driving modes within a small cycle range, simplifying the functional logic, and improving the driving mode switching efficiency and driving experience.

[0021] Similarly, the second control unit is a knob switch or a push-pull switch, and the setting order of each driving mode in the second type of driving mode includes: arranging each driving mode of the second type of driving mode in a second order to form a second forward circulation order and a second reverse circulation order opposite to the second forward circulation order.

[0022] Furthermore, the second type of driving modes includes snow mode, mud mode, sand mode, rock mode and wading mode, the second default driving mode is snow mode, and the setting order of each driving mode in the second type of driving modes includes:

[0023] The following modes are arranged in sequence and cycle: snow mode, mud mode, sand mode, rock mode, wading mode; or the following modes are arranged in sequence and cycle: snow mode, wading mode, rock mode, sand mode, mud mode.

[0024] As another improvement of the all-terrain driving mode switching method of the present invention, the first default driving mode is the most frequently used driving mode in the first type of driving modes. Preferably, according to the setting order of each driving mode in the first type of driving mode, the usage frequency of the corresponding driving mode decreases or increases in sequence.

[0025] The first default driving mode is defined according to the frequency of use. Among the driving modes suitable for road terrains, the most frequently used mode is generally the comfort mode. When switching from the second driving mode suitable for off-road terrain to the first driving mode, it is first in the first default driving mode, which is generally the comfort mode. The driver is likely to select this driving mode, thereby ending the control and stopping the switching; and if the switching continues, the next driving mode is also the one that the driver is likely to select, further improving the efficiency of driving mode switching.

[0026] Similarly, the second default driving mode is the most frequently used driving mode in the second type of driving modes. Preferably, according to the setting order of each driving mode in the second type of driving modes, the usage frequency of the corresponding driving modes decreases or increases in sequence.

[0027] As another improvement of the all-terrain driving mode switching method of the present invention, when it is necessary to control the vehicle to enter the first type of driving mode, the first control unit is operated:

[0028] If the current driving mode of the vehicle does not belong to the first type of driving mode, the vehicle switches to the first default driving mode in sequence according to the first default driving mode and in the order in which the driving modes in the first type of driving mode are set, including: the vehicle switches to the first default driving mode after one operation, and the vehicle switches to the first default driving mode after each additional operation in sequence according to the order in which the driving modes in the first type of driving mode are set;

[0029] If the vehicle's current driving mode belongs to the first category of driving modes, the vehicle performs corresponding switching according to the current driving mode and in the setting order of each driving mode in the first category of driving modes, including: after one operation, the vehicle switches to a driving mode that is located after the current driving mode in the setting order of each driving mode in the first category of driving modes, and each time the operation is performed, the vehicle performs corresponding switching in the setting order of each driving mode in the first category of driving modes.

[0030] The driving mode selected by the driver is determined by the number of operations combined with the current driving mode of the vehicle, so that each operation of the first control unit corresponds to a set driving mode, and if it is switched only within the first type of driving mode, it will switch cyclically on the basis of the current one; if it is switched from the second type of driving mode, it will switch cyclically starting from the first default driving mode. When there is no reminder in the car, the driver does not know where he is currently, which saves time and can be operated directly. In addition, the entire control logic is clear, simple and efficient.

[0031] Preferably, the first operating unit automatically resets after each operation. Through the automatic reset function, each time the driver operates the first operating unit, only an analog signal is output instead of continuous output, so that when the driver needs to switch modes, he does not need to care about the current state of the first operating unit and the current driving mode, and can switch between operations.

[0032] Similarly, when the vehicle needs to be controlled to enter the second driving mode, the second control unit is operated:

[0033] If the current driving mode of the vehicle does not belong to the second driving mode, the vehicle switches to the second default driving mode in sequence according to the setting order of each driving mode in the second driving mode, including: the vehicle switches to the second default driving mode after one operation, and the vehicle switches to the second default driving mode after each additional operation in sequence according to the setting order of each driving mode in the second driving mode;

[0034] If the vehicle's current driving mode belongs to the second type of driving mode, the vehicle performs corresponding switching according to the current driving mode and in the setting order of each driving mode in the second type of driving mode, including: after one operation, the vehicle switches to a driving mode that is located after the current driving mode in the setting order of each driving mode in the second type of driving mode, and each time the operation is performed, the vehicle performs corresponding switching in the setting order of each driving mode in the second type of driving mode.

[0035] Preferably, the second operating unit automatically resets after each operation.

[0036] As another improvement of the all-terrain driving mode switching method of the present invention,

[0037] When the vehicle is not powered on for the first time: when the vehicle is in the first driving mode when the power is turned off, the control command controls the vehicle to switch to the driving mode before the power is turned off; when the vehicle is in the second driving mode when the power is turned off, the control command controls the vehicle to switch to the first default driving mode;

[0038] When the vehicle is powered on for the first time: the vehicle is controlled to switch to the first default driving mode. This makes the initial startup of the vehicle simple and safe.

[0039] In order to solve the above technical problems, the present invention provides an all-terrain driving mode switching system, comprising a first control unit (1), a second control unit (2) and a third control unit (3) for accepting driver operation control, a controller (4) and an execution unit (5),

[0040] The first control unit (1) is used to identify first action information of a driver operating the first control unit (1);

[0041] The second control unit (2) is used to identify second action information of the driver operating the second control unit (2);

[0042] The third control unit (3) is used to identify third action information of the driver operating the third control unit (3);

[0043] The controller (4) comprises a storage module (41), a corresponding module (42) and an instruction module (43), wherein the storage module (41) stores a driving mode in a preset first type of driving mode corresponding to each first action information and a driving mode in a preset second type of driving mode corresponding to each second action information, and the corresponding module (42) is used to query based on the first action information or the second action information most recently identified by the storage module (41) and the current driving mode information of the vehicle, to determine the driving mode currently selected by the driver; the instruction module (43) is used to generate a control instruction for controlling the vehicle to switch to the driving mode currently selected by the driver, and is also used to generate a control instruction for controlling the vehicle to switch to the intelligent selection mode according to the third action information;

[0044] The execution unit (5) is used to execute the control instruction generated by the instruction module (43) to switch the vehicle to a corresponding driving mode.

[0045] The driver determines the required driving mode according to the actual terrain, determines the control unit according to the three major categories of road, off-road and intelligent, and operates directly. The corresponding vehicle will directly switch to the corresponding driving mode. The operation is simple and fast, and the driving mode switching efficiency is high.

[0046] As an improvement of the all-terrain driving mode switching system of the present invention, it also includes a memory module (6), wherein the memory module (6) is used to store the driving mode in which the vehicle is before power is turned off, and the instruction module (43) is also used to generate a control instruction for controlling the vehicle to switch the driving mode according to the storage information of the memory module (6) when the vehicle is powered on: when the vehicle is in the first type of driving mode when the power is turned off, a control instruction for controlling the vehicle to switch to the driving mode before power is turned off is generated; when the vehicle is in the second type of driving mode when the power is turned off, a control instruction for controlling the vehicle to switch to the first default driving mode is generated.

[0047] When the vehicle power level changes from off-state to on-state, it means the vehicle starts, and vice versa, the vehicle shuts down. Since the vehicle usually does not move between off-state and on-state, that is, it is in the same terrain state, the driving mode usually defaults to the driving mode before the last power-off, and the driver does not need to make repeated adjustments, which is more intelligent. However, when the last power-off was in the second driving mode suitable for off-road terrain, since it is generally considered that the parking is in a flat parking area, the driving mode when the power is turned on again can be set to the first driving mode suitable for road terrain.

[0048] Furthermore, when the vehicle is powered on for the first time, the vehicle is in the first default driving mode. When the vehicle is initially started, the initial driving mode is set to the first default driving mode in the first type of driving mode, preferably the comfort mode; when the vehicle is not powered on for the first time, the initial driving mode is set according to the above logic.

[0049] To sum up, the above-mentioned all-terrain driving mode switching method and system are adopted to divide the driving mode into two major driving modes suitable for roads and off-roads according to the terrain characteristics corresponding to the driving mode. With the assistance of the intelligent rotation mode, the three corresponding control units are controlled respectively, so as to integrate the driving modes of the same major category into a small cycle range, simplify the functional logic, and improve the mode switching efficiency while meeting the driving needs of multiple terrains, thereby improving the driving experience of the driver. While meeting the driving needs of multiple terrains, the mode switching efficiency is effectively improved, the driving experience of the driver is improved, and the problem of many steps and low switching efficiency in multi-terrain driving mode switching is solved.

[0054] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0055] Example 1

[0056] like Figure 1 As shown, the present invention provides an all-terrain driving mode switching method, which decomposes the driving mode into two categories, suitable for road terrain and off-road terrain, according to the terrain characteristics corresponding to the driving mode, and controls the switching through three control units, which are usually knob switches or push-pull switches. The method supports small cycle switching within each major category of driving mode and large cycle switching between different major categories, while meeting the driving needs of multiple terrains, improving the mode switching efficiency and enhancing the driver's driving experience.

[0057] Among them, the vehicle's driving modes are divided into first-category driving modes and second-category driving modes according to the applicable terrain characteristics. The first-category driving mode has multiple driving modes suitable for road terrain, including comfort mode, economy mode, sports mode and personalized mode. The first default driving mode is usually the most frequently used comfort mode; the second-category driving mode has multiple driving modes suitable for off-road terrain, including snow mode, mud mode, sand mode, rock mode and wading mode. The second default driving mode is usually the most frequently used snow mode.

[0058] This method specifically includes the following three usage scenarios:

[0059] 1. When the vehicle needs to be controlled to enter the first driving mode, the driver operates the first control unit, that is, rotates the corresponding knob switch or pushes and pulls the corresponding push-pull switch to switch the vehicle to the target driving mode.

[0060] Optionally, the rotary switch and push-pull switch corresponding to the first control unit are automatically reset after each operation, that is, they are reset after being rotated once or pushed and pulled once, and only one signal is output each time the operation is performed.

[0061] Optionally, when the knob switch is rotated clockwise or the push-pull switch is pushed, the vehicle cycles through the following settings in the following order: comfort mode → economy mode → sport mode → personalized mode → comfort mode; when the knob switch is rotated counterclockwise or the push-pull switch is pulled, the vehicle cycles through the following settings in the following order: comfort mode → personalized mode → sport mode → economy mode → comfort mode.

[0062] ① If the vehicle's current driving mode does not belong to the first type of driving mode, the vehicle switches to the corresponding mode in sequence according to the first default driving mode and the setting order of each driving mode in the first type of driving mode.

[0063] The specific operation process is: after one operation, the vehicle switches to the first default driving mode, and each time the operation is performed, the vehicle switches to the corresponding mode in the setting order of each driving mode in the first type of driving mode.

[0064] Take the knob switch as an example, if you rotate the knob switch clockwise once, the vehicle switches to comfort mode; if you rotate it clockwise again, the vehicle switches to economy mode; if you rotate it clockwise again, the vehicle switches to sports mode; if you rotate it clockwise again, the vehicle switches to personalized mode; if you rotate it clockwise again, the vehicle switches to comfort mode, and so on. If you rotate it counterclockwise once, it returns to the driving mode after the last operation. The time for rotating it again can be the time when the vehicle maintains the previous driving mode for a certain period of time.

[0065] Rotate the knob once counterclockwise to switch the vehicle to comfort mode; rotate it once counterclockwise to switch the vehicle to personalized mode; rotate it once counterclockwise to switch the vehicle to sports mode; rotate it once counterclockwise to switch the vehicle to economy mode; rotate it once counterclockwise to switch the vehicle to comfort mode, and so on. If the knob is rotated once at a certain moment, it will return to the driving mode after the last operation. The time for rotating the knob again can be the time when the vehicle keeps the previous driving mode for a certain period of time.

[0066] ② If the vehicle's current driving mode belongs to the first type of driving mode, the vehicle will switch accordingly according to the current driving mode and the setting order of each driving mode in the first type of driving mode.

[0067] The specific operation process is: after one operation, the vehicle switches to a driving mode that follows the current driving mode in the setting order of the driving modes in the first category of driving modes. Each time the operation is performed, the vehicle switches accordingly in the setting order of the driving modes in the first category of driving modes.

[0068] Assuming that the current vehicle is in the sport mode, the knob switch is arranged, that is, if the knob switch is rotated clockwise once, the vehicle switches to the personalized mode; if it is rotated clockwise again, the vehicle switches to the comfort mode; if it is rotated clockwise again, the vehicle switches to the economy mode; if it is rotated clockwise again, the vehicle switches to the sport mode; if it is rotated clockwise again, the vehicle switches to the personalized mode, and so on. If it is rotated counterclockwise once, it returns to the driving mode after the last operation. The time for rotating the knob again can be the time when the vehicle maintains the previous driving mode for a certain period of time.

[0069] If the knob switch is rotated counterclockwise once, the vehicle switches to economy mode; if it is rotated counterclockwise again, the vehicle switches to comfort mode; if it is rotated counterclockwise again, the vehicle switches to personalization mode; if it is rotated counterclockwise again, the vehicle switches to sports mode; if it is rotated counterclockwise again, the vehicle switches to economy mode, and so on. If the knob switch is rotated clockwise once at a certain moment, the vehicle returns to the driving mode after the last operation. The time for rotating the knob again can be the time when the vehicle maintains the previous driving mode for a certain period of time.

[0070] 2. When it is necessary to control the vehicle to enter the second driving mode, operate and control the second control unit, that is, rotate the corresponding knob switch or push and pull the corresponding push-pull switch to switch the vehicle to the target driving mode.

[0071] Optionally, the rotary switch and push-pull switch corresponding to the first control unit are automatically reset after each operation, that is, they are reset after being rotated once or pushed and pulled once, and only one signal is output each time the operation is performed.

[0072] Optionally, when the knob switch is rotated clockwise or the push-pull switch is pushed, the vehicle cycles through the following settings in the following order: snow mode → mud mode → sand mode → rock mode → wading mode → snow mode; when the knob switch is rotated counterclockwise or the push-pull switch is pulled, the vehicle cycles through the following settings in the following order: snow mode → wading mode → rock mode → sand mode → mud mode → snow mode.

[0073] ① If the vehicle's current driving mode does not belong to the second driving mode, the vehicle switches to the corresponding mode in sequence according to the second default driving mode and the setting order of each driving mode in the second driving mode.

[0074] The specific operation process is: after one operation, the vehicle switches to the second default driving mode. Each time the operation is performed, the vehicle switches to the corresponding mode in the setting order of each driving mode in the second driving mode.

[0075] Take the knob switch as an example, if the knob switch is rotated clockwise once, the vehicle switches to snow mode; if it is rotated clockwise again, the vehicle switches to wading mode; if it is rotated clockwise again, the vehicle switches to rock mode; if it is rotated clockwise again, the vehicle switches to sand mode; if it is rotated clockwise again, the vehicle switches to mud mode; if it is rotated clockwise again, the vehicle switches to snow mode, and so on. If it is rotated counterclockwise once, it returns to the driving mode after the last operation. The time for rotating the knob again can be the time when the vehicle maintains the previous driving mode for a certain period of time.

[0076] Rotate the knob switch counterclockwise once, the vehicle switches to snow mode; rotate it counterclockwise again, the vehicle switches to mud mode; rotate it counterclockwise again, the vehicle switches to sand mode; rotate it counterclockwise again, the vehicle switches to rock mode; rotate it counterclockwise again, the vehicle switches to wading mode, rotate it counterclockwise again, the vehicle switches to snow mode, and so on. If the knob is rotated clockwise once at a certain moment, it returns to the driving mode after the last operation. The time for rotating it again can be the time when the vehicle keeps the previous driving mode for a certain period of time.

[0077] ② If the vehicle's current driving mode belongs to the second type of driving mode, the vehicle will switch accordingly according to the current driving mode and the setting order of each driving mode in the second type of driving mode.

[0078] The specific operation process is: after one operation, the vehicle switches to the driving mode that is located after the current driving mode in the setting order of each driving mode in the second type of driving mode. Each time the operation is performed, the vehicle switches accordingly in the setting order of each driving mode in the second type of driving mode.

[0079] Assuming that the current vehicle is in wading mode, take the knob switch as an example, if the knob switch is rotated clockwise once, the vehicle switches to snow mode; if it is rotated clockwise once again, the vehicle switches to mud mode; if it is rotated clockwise once again, the vehicle switches to sand mode; if it is rotated clockwise once again, the vehicle switches to rock mode; if it is rotated clockwise once again, the vehicle switches to wading mode; if it is rotated clockwise once again, the vehicle switches to snow mode, and so on. If it is rotated counterclockwise once, it returns to the driving mode after the last operation. The time for rotating the knob again can be the time when the vehicle maintains the previous driving mode for a certain period of time.

[0080] Rotate the knob switch counterclockwise once, the vehicle switches to rock mode; rotate it counterclockwise again, the vehicle switches to sand mode; rotate it counterclockwise again, the vehicle switches to mud mode; rotate it counterclockwise again, the vehicle switches to snow mode; rotate it counterclockwise again, the vehicle switches to wading mode, rotate it counterclockwise again, the vehicle switches to rock mode, and so on. If you rotate the knob switch clockwise once at a certain moment, it will return to the driving mode after the last operation. The time for rotating it again can be the time when the vehicle keeps the previous driving mode for a certain period of time.

[0081] 3. When the vehicle needs to automatically select a driving mode, operate the third control unit. The third control unit can also be a knob switch, a push-pull switch or a button switch. Only one operation is required to enable the vehicle to automatically select and switch to a driving mode that conforms to the actual road condition information.

[0082] In addition, to illustrate the driving mode switching process, an example is given below: (The vehicle is powered on for the first time)

[0083] 1. The vehicle power gear changes from off state to on state, and the driving mode defaults to the comfort mode for highway cycling;

[0084] 2. If the vehicle needs to switch to other driving modes in the first driving mode suitable for highway terrain in the above driving situation, the switch corresponding to the first control unit is operated, and the switch is pushed (rotated clockwise) once to switch to the economic mode. The operation can be continued to switch to the sports mode, personalized mode, and comfort mode in a small cycle sequence. If the reverse operation is performed, the mode is switched in the reverse order;

[0085] 3. If the vehicle needs to switch to the intelligent selection mode in the above two driving conditions, directly press the switch corresponding to the third control unit to switch to the intelligent selection mode;

[0086] 4. If the vehicle needs to switch to the driving mode of the second driving mode suitable for off-road terrain in the above three driving conditions, operate the corresponding switch of the second control unit to directly switch to the snow mode. Continue to push (rotate clockwise) to switch to the mud mode, sand mode, rock mode, wading mode, and snow mode in sequence. If the reverse operation is performed, the mode switching is carried out in a reverse cycle;

[0087] 5. If the vehicle needs to switch to the intelligent selection mode in the above four driving conditions, the switch corresponding to the third control unit can be switched to the intelligent selection mode; if the driving mode within the first driving mode needs to be switched, the switch corresponding to the first control unit can be operated to directly switch to the comfort mode, and the other driving modes within the highway cycle can be switched by continuing to push (rotate) the operation;

[0088] 6. In the above three driving conditions, if you need to switch to a driving mode within the first driving mode suitable for road terrain, operate the switch corresponding to the first control unit to directly switch to the comfort mode. Continue to push (rotate) the operation to switch to other driving modes in the road cycle.

[0089] Example 2 is as follows (the vehicle is not powered on for the first time):

[0090] 1. When the vehicle power gear changes from the off state to the on state, the driving mode defaults to a mode in the first category of driving modes suitable for road terrain before the last power off, assuming it is the comfort mode;

[0091] 2. If the vehicle needs to switch to other driving modes in the first driving mode under the driving condition described in the first paragraph, the switch corresponding to the first control unit is pushed (rotated clockwise) once to switch to the economic mode. The switch can be switched to other driving modes in the first driving mode in a small cycle sequence by continuing to operate. If the reverse operation is performed, the mode switching is performed in a reverse sequence.

[0092] 3. The subsequent steps are the same as those in Example 1 (powering on the vehicle) and will not be repeated here.

[0093] like Figure 2 As shown, the present invention provides a system based on the above-mentioned all-terrain driving mode switching method, comprising a first control unit (1), a second control unit (2) and a third control unit (3) for accepting driver operation control, as well as a controller (4) and an execution unit (5),

[0094] The first control unit (1) is used to identify first action information of a driver operating the first control unit (1);

[0095] The second control unit (2) is used to identify second action information of the driver operating the second control unit (2);

[0096] The third control unit (3) is used to identify third action information of the driver operating the third control unit (3);

[0097] The controller (4) comprises a storage module (41), a corresponding module (42) and an instruction module (43), wherein the storage module (41) stores a driving mode in a preset first type of driving mode corresponding to each first action information and a driving mode in a preset second type of driving mode corresponding to each second action information, and the corresponding module (42) is used to query based on the first action information or the second action information most recently identified by the storage module (41) and the current driving mode information of the vehicle, to determine the driving mode currently selected by the driver; the instruction module (43) is used to generate a control instruction for controlling the vehicle to switch to the driving mode currently selected by the driver, and is also used to generate a control instruction for controlling the vehicle to switch to the intelligent selection mode according to the third action information;

[0098] The execution unit (5) is used to execute the control instruction generated by the instruction module (43) to switch the vehicle to a corresponding driving mode.

[0099] Optionally, the system further comprises a memory module (6), wherein the memory module (6) is used to store the driving mode in which the vehicle was before being powered off, and the instruction module (43) is further used to generate, when the vehicle is powered on, a control instruction for controlling the vehicle to switch driving modes according to the storage information of the memory module (6): when the vehicle is in the first type of driving mode when powered off, a control instruction for controlling the vehicle to switch to the driving mode before being powered off is generated; when the vehicle is in the second type of driving mode when powered off, a control instruction for controlling the vehicle to switch to the first default driving mode is generated.

[0100] The vehicle power gear changes from the power-off state to the power-on state, indicating that the vehicle is started, and vice versa. For non-first-time vehicle power-on, since the vehicle usually does not move between power-off and power-on, that is, it is in the same terrain state, through the function of the memory module 6, when the vehicle is just started, the driving mode usually defaults to the driving mode before the last power-off, and the driver does not need to make repeated adjustments, and can be used directly, which is more convenient, faster, and smarter. When the vehicle is in the second driving mode before powering off, in order to improve the comfort and safety of the vehicle when starting, since the second driving mode requires higher operating skills and strength, the driving mode when the vehicle is started is set to the first default driving mode, i.e., the comfort mode.

[0101] When the vehicle is powered on for the first time, the memory module 6 does not work, and the vehicle control system initially sets the vehicle to the first default driving mode, preferably the comfort mode; when it is not the first time the vehicle is powered on, the initial driving mode is set according to the above logic.

[0102] When in use, the vehicle power gear changes from the power-off state to the power-on state. If it is the initial start, the driving mode defaults to the comfort mode of the first driving mode, which can be freely set at the factory. If it is not the initial start, it switches to the driving mode or comfort mode before the last power-off, and then drives normally:

[0103] If you need to switch to a driving mode within the first type of driving mode, operate the first control unit 1: rotate the knob switch or push the push-pull switch once or multiple times to achieve cyclic adjustment within the first type of driving mode; if you need to switch to the smart selection mode, directly press the switch of the third control unit 3 to switch to the smart selection mode; if you need to switch to a driving mode within the second type of driving mode, operate the second control unit 2: rotate the knob switch or push the push-pull switch once or multiple times to achieve cyclic adjustment within the second type of driving mode.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
