[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] With the rapid development of society, cars are no longer as rare and precious as they were a decade or so ago; they are now ubiquitous on the streets, a necessity in many households. People's demands for vehicles have also expanded beyond just driving; they are now more focused on comfort, intelligence, automation, and safety. To meet these customer needs, the automotive industry has seen rapid development in autonomous driving technology in recent years. The driving assistance system mentioned in this application is one function of autonomous driving technology, mainly including the following sub-functions:

[0053] Longitudinal driving assistance is a driving assistance function that provides drivers with longitudinal control of the vehicle by controlling the vehicle's brakes and accelerator. It mainly includes adaptive cruise control, which monitors the driving environment ahead of the vehicle in real time and automatically adjusts the vehicle's speed within a set speed range to adapt to changes in the driving environment caused by vehicles or road conditions ahead.

[0054] Lateral and longitudinal driving assistance: The system simultaneously controls the vehicle's steering, braking, and throttle, providing the driver with lateral and longitudinal driving assistance functions, mainly including the following:

[0055] Traffic jam assist / integrated cruise assist monitors the driving environment in front of and around the vehicle in real time and automatically controls the vehicle laterally and longitudinally.

[0056] High-speed navigation driving assistance, on urban expressways and highways covered by high-precision maps, the autonomous driving system controls the vehicle to automatically assist driving according to the navigation route, ultimately realizing automatic navigation driving service from the starting point to the destination within the high-precision map range.

[0057] Urban navigation driving assistance: On general roads in urban areas covered by high-precision maps, the autonomous driving system controls the vehicle to automatically assist driving according to the navigation route, ultimately realizing automatic navigation driving service from the starting point to the destination within the high-precision map range.

[0058] This application primarily aims to address the issues arising from the chaotic or unreasonable architectural definitions of driving assistance systems in various OEM models, which cause the following problems for users when using these systems:

[0059] (1) The system’s switch definition is unreasonable. It is inconvenient or difficult for users to turn the function on or off when using the vehicle, which can easily cause user complaints and reduce the product’s competitiveness.

[0060] (2) Difficulty in selecting the various sub-functions of the driving assistance system or not knowing how to select them makes it difficult to use, which can easily lead to user complaints and reduce the product's competitiveness.

[0061] (3) The lack of clarity or difficulty in selecting user-personalized settings related to driving assistance systems can easily lead to user complaints and reduce the product's competitiveness.

[0062] (4) Users are unclear or unaware of the current working mode of the vehicle, which may lead to misuse and danger.

[0063] In view of this, embodiments of this application provide a method for switching driving assistance functions, enabling drivers to quickly select and activate appropriate driving assistance functions. The method is executed by a system controller, such as... Figure 1 As shown, the method includes steps S101, S102, and S103, wherein:

[0064] In step S101, the current gear position and the driving assistance system switch status are identified.

[0065] In step S102, when the current gear is forward and the driving assistance system switch is in the off state, the gear control signal is monitored.

[0066] In step S103, when the first gear control signal is detected for the first time, the adaptive cruise control function is activated. The first gear control signal is used to control the transmission to engage a forward gear.

[0067] It is understood that the driving assistance function switching method provided in this application embodiment is applicable when the driving assistance system is in the off state. In this case, the adaptive cruise function (adaptive cruise function is one of the driving assistance functions) is activated directly according to the driver's operation of engaging a forward gear, so that the driver does not need to find a physical button to activate the driving assistance function and can select and activate the appropriate driving assistance function.

[0068] In this embodiment, the first gear control signal can be triggered by a column shifter, an electronic gear lever, or a gear shift knob. In conventional control schemes, if the vehicle's current gear is a drive, even if the driver triggers the first gear control signal by operating the column shifter, electronic gear lever, or gear shift knob, the first gear control signal is used to control the transmission to engage a drive gear. The transmission and / or other vehicle mechanisms will not perform any additional operations. The first gear control signal is perceived as being triggered due to driver error, since the vehicle's current gear is already a drive.

[0069] However, for vehicles equipped with driving assistance functions, if the driver is unsure how to activate these functions or which function to use, and is not accustomed to searching for specific buttons on the steering wheel or center console screen, they might, even when the vehicle is already in drive, try to trigger the first gear control signal by operating the column shifter, electronic gear lever, or gear selector knob to see if the vehicle can enter another driving state, as this might be the only familiar operation for the driver. In this situation, the driving assistance function switching method provided in this application can activate the adaptive cruise control function, thereby putting the vehicle into a higher level of driving assistance, making it easier for the driver to start trying out the vehicle's driving assistance functions, reducing the learning cost, and improving the driving experience. Adaptive cruise control refers to the ability of a vehicle to control the throttle opening, brake opening, and transmission gear based on the set maximum speed, road speed limit signs identified by cameras, the real-time speed of the vehicle in front, and the real-time distance to the current vehicle. This allows the vehicle to maintain a fixed distance from the vehicle in front as much as possible without exceeding the speed limit, and to travel at the speed limit when there is no vehicle in front, thus achieving longitudinal (vehicle forward direction) control.

[0070] In addition to adaptive cruise control, the vehicle may also be equipped with more advanced driving assistance features; therefore, in some alternative embodiments, the method further includes:

[0071] When the first gear control signal is detected for the second time, the current position of the vehicle is obtained.

[0072] Determine whether the high-precision map covers the current location based on the current location.

[0073] When the high-precision map does not cover the current location, activate the traffic jam assist function or the integrated cruise assist function; when the high-precision map covers the current location, activate the highway navigation driving assist function or the city navigation driving assist function.

[0074] Understandably, after the adaptive cruise control function is activated, the driver may find that the vehicle has entered a different driving state. At this time, the driver may try to trigger the first gear control signal again by operating the column shifter, electronic gear lever or shift knob, in order to see if the vehicle can enter other driving states.

[0075] A higher level of driving assistance than adaptive cruise control is longitudinal + lateral driving assistance. This means that the vehicle can not only control its speed and distance, but also control the steering wheel angle, so that the vehicle can stay in the current lane, change lanes according to the traffic conditions of different lanes, and even autonomously enter and exit highway ramps or turn at city intersections.

[0076] However, accurately merging lanes based on traffic flow in different lanes, or even autonomously entering and exiting highway ramps or turning at city intersections, clearly relies on high-precision maps. Highway navigation driving assistance or city navigation driving assistance functions can only be activated when the high-precision map covers the vehicle's current location. If the high-precision map does not cover the vehicle's current location, only traffic jam assist or integrated cruise assist functions can be activated, controlling both speed and distance while simultaneously controlling steering wheel angle to keep the vehicle in its current lane.

[0077] Understandably, when a high-precision map covers the vehicle's current location, it can further determine whether the current location is on a highway or in the city. If the current location is on a highway, the highway navigation driving assistance function is activated. The vehicle can control not only its speed and following distance but also its steering wheel angle, thus maintaining its position in the current lane and merging into different lanes based on traffic flow, even autonomously entering and exiting highway ramps. If the current location is in the city, the city navigation driving assistance function is activated. The vehicle can control not only its speed and following distance but also its steering wheel angle, thus maintaining its position in the current lane and merging into different lanes based on traffic flow, even autonomously turning at city intersections.

[0078] In some optional embodiments, the method further includes:

[0079] When the current gear is forward and the driving assistance system is in the on state, the gear control signal is monitored.

[0080] When the second gear control signal or the third gear control signal is detected, the driving assistance system switch is switched to the off state. The second gear control signal is used to control the transmission to engage neutral, and the third gear control signal is used to control the transmission to engage reverse.

[0081] Understandably, in addition to potentially triggering the first gear control signal by operating the column shifter, electronic gear lever, or gear selector knob to try and get the vehicle into other driving states, drivers may also operate the column shifter, electronic gear lever, or gear selector knob to trigger the second or third gear control signal, causing the transmission to engage neutral or reverse gear accordingly. In this case, the shifting will proceed normally, and the driving assistance system will be deactivated.

[0082] The driving assistance function switching method provided in this application can activate the adaptive cruise control function directly based on the driver's operation of shifting into forward gear when the driving assistance system is turned off and the current gear is forward. This eliminates the need for the driver to find a physical button to activate the driving assistance function and allows them to select and activate the appropriate driving assistance function, reducing the learning cost and improving the driving experience.

[0083] This application also provides a method for switching driving assistance functions, enabling the driver to quickly select and activate appropriate driving assistance functions. The method is executed by a system controller. Figure 2 As shown, the method includes steps S201, S202, S203, S204, S205, S206, and S207, wherein:

[0084] In step S201, the current gear position and the driving assistance system switch status are identified.

[0085] In step S202, when the current gear is forward and the driving assistance system switch is in the on state, the gear control signal is monitored.

[0086] In step S203, when two first gear control signals are detected consecutively, the current function of the driving assistance system is determined.

[0087] In step S204, when the current function of the driving assistance system is adaptive cruise control, the current position of the vehicle is obtained.

[0088] In step S205, it is determined whether the high-precision map covers the current location based on the current location.

[0089] If the judgment result of step S205 is negative, that is, if the high-precision map does not cover the current location, proceed to step S206.

[0090] In step S206, the traffic jam assist function or integrated cruise assist function is activated.

[0091] If the judgment result of step S205 is yes, that is, the high-precision map covers the current location, proceed to step S207.

[0092] In step S207, the high-speed navigation driving assistance function or the city navigation driving assistance function is activated.

[0093] It is understood that the driving assistance function switching method provided in this application embodiment is applicable when the driving assistance system is in the on state. In this case, the traffic jam assist function, integrated cruise assist function, highway navigation driving assist function or city navigation driving assist function is activated directly based on the driver's two operations of engaging the forward gear. This allows the driver to select and activate the appropriate driving assistance function without having to find a physical button to activate the driving assistance function.

[0094] In this embodiment, the first gear control signal can be triggered by a column shifter, an electronic gear lever, or a gear shift knob. In conventional control schemes, if the vehicle's current gear is a drive, even if the driver triggers the first gear control signal two or more times by operating the column shifter, electronic gear lever, or gear shift knob, the first gear control signal is used to control the transmission to engage a drive gear, and the transmission and / or other vehicle mechanisms will not perform any additional operations. The first gear control signal is perceived as being triggered due to driver error, since the vehicle's current gear is already a drive.

[0095] However, for vehicles equipped with driving assistance functions, if the driver is unsure how to switch between these functions or which function to switch to, and is not accustomed to searching for specific buttons on the steering wheel or center console screen to activate them, the driver may repeatedly trigger the first gear control signal by operating the gearshift lever, electronic gear selector, or gear knob, even when the vehicle is already in drive, to try and switch to another driving mode, as this may be the only familiar operation. In this situation, the driving assistance function switching method provided in this application allows the vehicle to enter a higher level of driving assistance, making it easier for the driver to begin using the vehicle's driving assistance functions, reducing the learning curve and improving the driving experience.

[0096] The vehicle may currently have more than just adaptive cruise control activated, including traffic jam assist or integrated cruise assist. In this case, if the driver repeatedly triggers the first gear control signal by operating the column shifter, electronic shift lever, or gear selector knob, the system can reassess whether the vehicle's current location is covered by a high-precision map, thereby determining whether a higher level of highway navigation driving assistance or city navigation driving assistance can be activated.

[0097] Therefore, in some alternative embodiments, the method further includes:

[0098] When the current function of the driving assistance system is traffic jam assist or integrated cruise assist, obtain the vehicle's current location.

[0099] Determine whether the high-precision map covers the current location based on the current location.

[0100] When a high-precision map covers the current location, activate the highway navigation driving assistance function or the city navigation driving assistance function.

[0101] Understandably, when a high-precision map covers the vehicle's current location, it can further determine whether the current location is on a highway or in the city. If the current location is on a highway, the highway navigation driving assistance function is activated. The vehicle can control not only its speed and following distance but also its steering wheel angle, thus maintaining its position in the current lane and merging into different lanes based on traffic flow, even autonomously entering and exiting highway ramps. If the current location is in the city, the city navigation driving assistance function is activated. The vehicle can control not only its speed and following distance but also its steering wheel angle, thus maintaining its position in the current lane and merging into different lanes based on traffic flow, even autonomously turning at city intersections.

[0102] In some optional embodiments, the method further includes:

[0103] When the current gear is forward and the driving assistance system is in the on state, the gear control signal is monitored.

[0104] When the second gear control signal or the third gear control signal is detected, the driving assistance system switch is switched to the off state. The second gear control signal is used to control the transmission to engage neutral, and the third gear control signal is used to control the transmission to engage reverse.

[0105] Understandably, in addition to potentially triggering the first gear control signal by operating the column shifter, electronic gear lever, or gear selector knob to try and get the vehicle into other driving states, drivers may also operate the column shifter, electronic gear lever, or gear selector knob to trigger the second or third gear control signal, causing the transmission to engage neutral or reverse gear accordingly. In this case, the shifting will proceed normally, and the driving assistance system will be deactivated.

[0106] The driving assistance function switching method provided in this application can activate higher-level traffic jam assist, integrated cruise assist, highway navigation driving assist, or city navigation driving assist functions directly based on the driver's multiple triggering of shifting into forward gear when the driving assistance system is on and the current gear is forward. This eliminates the need for the driver to find a physical button to activate the driving assistance function and allows them to select and activate the appropriate driving assistance function, reducing the learning cost and improving the driving experience.

[0107] This application embodiment also provides a driving assistance function switching device, enabling the driver to quickly select and activate the appropriate driving assistance function. The device is installed in the system controller, such as... Figure 3 As shown, the device includes:

Alternatively, when the driving assistance system is on and the current gear is forward, it can activate higher-level traffic jam assist, integrated cruise assist, highway navigation driving assist, or city navigation driving assist functions directly based on the driver's repeated operations of shifting into a forward gear. This eliminates the need for the driver to search for a physical button to activate the driving assistance function, allowing them to select and activate the appropriate driving assistance function, reducing the learning cost and improving the driving experience.
