Description

Technical Field

[0001] This application relates to the fields of automotive hardware device control and driving assistance technology, specifically to a method, device, and vehicle for adjusting the speed and time distance of a driving assistance system. Background Technology

[0002] As people's living standards improve, automobiles are becoming increasingly intelligent and technologically advanced, leading to higher demands from users for driver assistance features. To meet these needs, vehicles equipped with L1-L2 driver assistance systems are now in mass production. L2 driver assistance systems include low-order longitudinal assist control functions and high-order lateral and longitudinal assist control functions. During operation, the driver can adjust the vehicle's speed as needed based on road conditions, road environment, and personal driving habits. In addition to adjusting speed, the driver can also adjust the relative distance to the vehicle in front (time distance).

[0003] Currently, there are two main ways to adjust the speed: steering wheel buttons, steering wheel scroll wheel, and steering wheel lever.

[0004] Speed ​​can be adjusted by pressing the buttons on the steering wheel, either by short press or long press. A short press increases or decreases the speed by 1 km / h, while a long press increases or decreases the speed by 5 km / h per second; or a short press increases or decreases the speed by 5 km / h, while a long press increases or decreases the speed by 1 km / h per second.

[0005] Speed ​​is adjusted by scrolling the wheel on the steering wheel, which can be done slowly or quickly. A slow scroll up or down increases / decreases the speed by 1 km / h, while a quick scroll up or down increases / decreases the speed by 5 km / h; or a slow scroll up or down increases / decreases the speed by 5 km / h, while a quick scroll up or down increases / decreases the speed by 1 km / h.

[0006] Speed ​​is adjusted via the steering wheel levers, which can be used to adjust the vehicle speed by moving the levers up / down or long / short. A short upward flick increases or decreases the speed by 5 km / h, and a short downward flick increases or decreases the speed by 5 km / h; a long upward flick increases or decreases the speed by 1 km / h, and a short downward flick increases or decreases the speed by 1 km / h.

[0007] However, the current methods for adjusting speed using steering wheel buttons, steering wheel scroll wheels, and steering wheel side levers have the following main problems:

[0008] Question 1: The steering wheel integrates multiple buttons on both sides. If the user is not fully familiar with the function and location of each button, they need to look down to find and confirm the button location before adjusting the speed. Since the vehicle is always in motion when the speed needs to be adjusted, this operation increases the driving risk.

[0009] Question 2: There are many buttons on the steering wheel, and these are all frequently used buttons. Users may easily confuse the speed adjustment buttons with other buttons, leading to misoperation.

[0010] Question 3: Regarding the steering wheel scroll wheel adjustment method, it is not easy for users to learn how to scroll quickly and slowly, making it difficult for users to quickly master the speed adjustment function;

[0011] Question 4: The position of the steering wheel side stalk is close to that of the turn signal stalk or windshield wiper stalk, which makes it easy for users to operate it by mistake. For example, when a user needs to turn on the turn signal in an emergency, it increases the driving risk and is not easy for users to learn and master.

[0012] Currently, there are three main ways to adjust the time distance: steering wheel buttons, steering wheel scroll wheel, and steering wheel side lever knob.

[0013] Adjust the distance by pressing the buttons on the steering wheel. If there is one distance adjustment button, pressing it will increase or decrease the distance, and the adjustment can be cycled. If there are two distance adjustment buttons, pressing one button will increase the distance and pressing the other button will decrease the distance.

[0014] The time distance is adjusted using the steering wheel scroll wheel. You can adjust it by pressing the scroll wheel left or right, which will increase or decrease the time distance.

[0015] Adjusting the time distance using the steering wheel-side stalk knob is primarily found in vehicles where driver assistance functions are activated or deactivated via the steering wheel-side stalk. The time distance can be increased or decreased by rotating the knob clockwise or counterclockwise.

[0016] However, existing methods for adjusting time intervals mainly have the following problems:

[0017] Problem 1: Adjusting via steering wheel buttons or scroll wheel has issues such as buttons being difficult to find, inability to operate blindly, and easy misoperation;

[0018] Question 2: Adjusting via the steering wheel side lever knob has several drawbacks. The knob is too obscure, making it difficult for users to learn and master. Furthermore, adjusting the knob requires one hand to be off the steering wheel, increasing driving risks.

[0019] In related technologies, a vehicle adaptive cruise control button control device (application number: CN205365590U) is proposed. It only connects multiple buttons to the body controller to increase or decrease the vehicle's cruise speed or distance. It does not adjust the vehicle's speed or distance according to the user's driving intention, resulting in inaccurate speed and distance adjustment. Summary of the Invention

[0020] One objective of this invention is to provide a method, apparatus, and vehicle for adjusting the speed and distance of a driving assistance system, thereby addressing the limitations of existing methods for adjusting the speed and distance of driving assistance systems, which are constrained by the characteristics of the hardware itself and the deficiencies of existing solutions, and thus cannot fully achieve the efficiency and ease of use of adjusting the speed and distance of a car's driving assistance system. A second objective is to provide an apparatus for adjusting the speed and distance of a driving assistance system. A third objective is to provide a vehicle.

[0021] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The device is the cruise speed reduction toggle device, and the toggle method is the long-duration toggle. When there is a speed limit requirement ahead of the vehicle and the vehicle's current speed is greater than the speed limit value corresponding to the speed limit requirement, the vehicle's cruise speed is set to the speed limit value corresponding to the speed limit requirement, and the vehicle's current speed is reduced according to the second preset deceleration strategy until the current speed is reduced to a preset minimum speed. When there is a speed limit requirement ahead of the vehicle and the vehicle's current speed is less than or equal to the speed limit value corresponding to the speed limit requirement, the vehicle's current speed is reduced according to the second preset deceleration strategy until the current speed is reduced to a preset minimum speed. When there is no speed limit requirement ahead of the vehicle, the vehicle's current speed is directly reduced according to the second preset deceleration strategy.

[0034] Further, determining the vehicle's speed adjustment strategy and / or time-distance adjustment strategy based on the target toggle device and the toggle method includes: if the target toggle device is the cruise speed increase toggle device and the toggle method is the short-time toggle, then determining whether the vehicle's current speed has increased to a preset maximum speed, and if the current speed has not increased to the preset maximum speed, increasing the vehicle's current speed according to a first preset speed increase strategy; stopping the increase of the current speed when the current time-distance increases to the preset maximum speed; if the target toggle device is the cruise speed increase toggle device and the toggle method is the long-time toggle, then increasing the vehicle's current speed according to a second preset speed increase strategy until the vehicle's current speed increases to the preset maximum speed.

[0054] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0055] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0056] This embodiment proposes a method for adjusting the speed and time distance of a driving assistance system, such as... Figure 1 As shown, the method for adjusting the speed and distance of the driving assistance system includes the following steps:

[0057] Several toggle devices are installed behind the horizontal bar of the vehicle's steering wheel. For example... Figure 2 As shown, two or four steering wheel toggle devices can be installed; this embodiment describes four toggle devices. Multiple toggle devices are installed on both sides behind the horizontal bar of the steering wheel inside the vehicle, arranged in the 3 o'clock and 9 o'clock areas of the steering wheel. The driver can easily reach and operate them with any finger except the thumb. The toggle devices can be fixed or movable. Fixed toggle devices remain stationary with the dashboard, while movable toggle devices remain stationary with the steering wheel. This embodiment uses a movable type, which can better support the driver in adjusting speed or distance while turning the steering wheel. The toggle devices are used to collect the driver's operating intentions and support the driver's operation. The driver can express the desire to adjust speed and distance by pressing the toggle device in the driver's direction.

[0058] In step S101, when any toggle device is detected to be toggled, it is determined whether the vehicle's driver assistance system is in a preset active state.

[0059] The preset activation state is that the vehicle's driver assistance lateral control function is in operation and continuously assists the driver in controlling the vehicle's lateral and longitudinal movements. The lateral and longitudinal control of the vehicle belongs to the driver assistance system.

[0060] Specifically, this embodiment monitors the driver's operation. In any state of the vehicle, if the driver is detected to move any toggle device at any time, the system will begin to determine whether the vehicle's driver assistance system is in a preset active state.

[0061] In some embodiments, the multiple toggle devices include a cruise speed reduction toggle device, a time interval reduction toggle device, a time interval increase toggle device, and a cruise speed increase toggle device.

[0062] Specifically, the cruise speed reduction toggle device can reuse the function of setting the speed limit to the cruise speed with a single button. The driver can toggle it in the driver's direction to achieve both long and short toggle operations. Figure 2 Position 2 is shown in the image; the time-distance toggle device can be toggled by the driver in the driver's direction, allowing for both long and short toggle operations, such as... Figure 2 As shown in position 4; an added time interval toggle device is added, which the driver can toggle in the driver's direction to achieve long and short toggle, such as Figure 2 As shown in position 3; a cruise speed toggle device has been added, which can reuse and reactivate the driver assistance system. The driver can toggle it in the driver's direction to achieve both long and short toggle functions, such as... Figure 2 Position 1 is shown in the image.

[0063] It should be noted that the physical layout of each toggle device should take into account the application scenario for the corresponding function, and can also be left to users to customize.

[0064] Furthermore, in some embodiments, after determining whether the vehicle's driving assistance system is in a preset active state, the method further includes: if the driving assistance system is not in a preset active state, determining that the driving assistance system is in a preset temporary deactivation state; if the driving assistance system is in a preset temporary deactivation state, determining whether the cruise speed increase toggle device among the multiple toggle devices has been activated, and controlling the driving assistance system to enter a preset active state when the cruise speed increase toggle device is activated; otherwise, maintaining the vehicle's current operating state.

[0065] The preset temporary exit state is the state in which the function of the driving assistance system is temporarily exited due to various reasons after the system is activated. In the preset temporary exit state, the driving assistance control is in a non-operating state, and the control of the vehicle belongs to the driver.

[0066] Specifically, when the driving assistance system is not in a preset active state, if the driving assistance system is in a preset temporary deactivation state, it is determined whether the cruise speed increase toggle among the multiple toggle devices has been activated. If it has been activated, the driving assistance system is controlled to enter the preset active state. If the cruise speed increase toggle among the multiple toggle devices has not been activated, the current state of the vehicle is maintained. If the driving assistance system is not in a preset temporary deactivation state, the current state of the vehicle is maintained and no response is made.

[0067] In step S102, if the driving assistance system is in a preset active state, the target toggle device and toggle method among the multiple toggle devices are obtained, and the vehicle speed adjustment strategy and / or time distance adjustment strategy are determined according to the target toggle device and toggle method.

[0068] In some embodiments, the toggle method includes short-duration toggle and long-duration toggle, wherein the duration of short-duration toggle is less than a first preset duration, and the duration of long-duration toggle is greater than a second preset duration, wherein the first preset duration is less than or equal to the second preset duration.

[0069] It should be understood that a short-term toggle means that after the driver presses the toggle device, he releases it within 500ms (the specific value is subject to actual calibration and experience depending on the vehicle model, and no specific limit is made) to allow the toggle device to reset; a long-term toggle means that after the driver presses the toggle device, he does not release it within 500ms and continues to press the toggle device, and the toggle device does not reset.

[0070] Specifically, if the driving assistance system is in a preset active state, the system monitors the driver's intervention operations to determine the driver's intentions. For example, if the driver presses the toggle devices on both sides of the steering wheel, the driving assistance system will perform corresponding time-distance adjustment, speed adjustment, function restoration, and other operations. The system will also combine the current road speed limit information and the function's operating status to determine the driver's target toggle device and obtain the driver's toggle method for the target toggle device, including short-term and long-term toggle.

[0071] Furthermore, in this embodiment, the vehicle speed adjustment strategy and / or time-distance adjustment strategy are determined based on the driver's target toggle device and toggle method.

[0072] In step S103, the vehicle's cruising speed is adjusted according to the speed adjustment strategy and / or the vehicle's current distance is adjusted according to the time-distance adjustment strategy.

[0073] Furthermore, in some embodiments, determining the vehicle's speed adjustment strategy and / or distance adjustment strategy based on the target toggle device and the toggle method includes: if the target toggle device is a cruise speed reduction toggle device and the toggle method is short-term toggle, then when there is a speed limit requirement ahead of the vehicle and the vehicle's current speed is greater than the speed limit value corresponding to the speed limit requirement, the vehicle's cruise speed is set to the speed limit value corresponding to the speed limit requirement; when there is a speed limit requirement ahead of the vehicle and the vehicle's current speed is less than or equal to the speed limit value corresponding to the speed limit requirement, the vehicle's current speed is reduced according to a first preset deceleration strategy; when there is no speed limit requirement ahead of the vehicle, the vehicle's current speed is directly reduced according to the first preset deceleration strategy; if The target-type toggle device is a cruise speed reduction toggle device, and the toggle method is a long-term toggle. When there is a speed limit requirement in front of the vehicle and the vehicle's current speed is greater than the corresponding speed limit value, the vehicle's cruise speed is set to the corresponding speed limit value, and the vehicle's current speed is reduced according to the second preset deceleration strategy until the current speed is reduced to the preset minimum speed. When there is a speed limit requirement in front of the vehicle and the vehicle's current speed is less than or equal to the corresponding speed limit value, the vehicle's current speed is reduced according to the second preset deceleration strategy until the current speed is reduced to the preset minimum speed. When there is no speed limit requirement in front of the vehicle, the vehicle's current speed is reduced directly according to the second preset deceleration strategy.

[0074] Specifically, if the target toggle device detected by the driver is a cruise speed reduction toggle device, and the toggle is a short-term toggle, it is determined whether there is a speed limit or speed camera ahead of the vehicle. If there is a speed limit ahead and the vehicle's current speed is greater than the corresponding speed limit value, the vehicle's cruise speed is set to the corresponding speed limit value; if there is a speed limit ahead and the vehicle's current speed is less than or equal to the corresponding speed limit value, the vehicle's current speed is reduced according to the first preset deceleration strategy (i.e., cruise speed reduced by 5 km / h or 1 km / h); if there is no speed limit ahead, the vehicle's current speed is reduced according to the first preset deceleration strategy (i.e., cruise speed reduced by 5 km / h or 1 km / h).

[0075] Furthermore, if the target toggle device detected by the driver is a cruise speed reduction toggle device, and the toggle method is a long-term toggle, it is determined whether there is a speed limit or speed camera ahead of the vehicle. If there is a speed limit ahead of the vehicle, and the vehicle's current speed is greater than the corresponding speed limit value, the vehicle's cruise speed is set to the corresponding speed limit value, and the vehicle's current speed is reduced to a preset minimum speed according to the second preset deceleration strategy (i.e., a decrease of 5 km / h or 1 km / h per second) until the speed no longer decreases; if there is a speed limit ahead of the vehicle, and the vehicle's current speed is less than or equal to the corresponding speed limit value, the vehicle's current speed is reduced to a preset minimum speed according to the second preset deceleration strategy (i.e., a decrease of 5 km / h or 1 km / h per second) until the speed no longer decreases; if there is no speed limit ahead of the vehicle, the vehicle's current speed is directly reduced according to the second preset deceleration strategy (i.e., a decrease of 5 km / h or 1 km / h per second).

[0076] Furthermore, in some embodiments, determining the vehicle speed adjustment strategy and / or time-distance adjustment strategy based on the target toggle device and the toggle method includes: if the target toggle device is a cruise speed increase toggle device and the toggle method is a short-term toggle, then determining whether the vehicle's current speed has increased to a preset maximum speed, and if the current speed has not increased to the preset maximum speed, increasing the vehicle's current speed according to a first preset speed increase strategy; if the current speed has increased to the preset maximum speed, stopping the increase of the current speed; if the target toggle device is a cruise speed increase toggle device and the toggle method is a long-term toggle, then increasing the vehicle's current speed according to a second preset speed increase strategy until the vehicle's current speed increases to the preset maximum speed.

[0077] It should be understood that if the driver's target toggle device is detected as a cruise speed increase toggle device, and the toggle is a short-term toggle, it is determined whether the vehicle's current speed has increased to the preset maximum speed. If the vehicle's current speed has increased to the preset maximum speed, the increase in current speed is stopped. If the vehicle's current speed has not increased to the preset maximum speed, the vehicle's current speed is increased according to the first preset speed increase strategy (i.e., cruise speed increases by 5 km / h or 1 km / h). If the driver's target toggle device is detected as a cruise speed increase toggle device, and the toggle is a long-term toggle, it is determined whether the vehicle's current speed has increased to the preset maximum speed. If the current vehicle speed has not increased to the preset maximum speed, the vehicle's current speed is increased to the preset maximum speed according to the second preset speed increase strategy (i.e., speed increases by 1 km / h or 5 km / h per second). If the current vehicle speed has increased to the preset maximum speed, the increase in current speed is stopped.

[0078] Furthermore, in some embodiments, determining the vehicle speed adjustment strategy and / or time-distance adjustment strategy based on the target toggle device and the toggle method includes: if the target toggle device is a time-distance reduction toggle device and the toggle method is a short-term toggle, then the current time-distance of the vehicle is reduced according to a first preset time-distance reduction strategy; if the target toggle device is a time-distance reduction toggle device and the toggle method is a long-term toggle, then the current time-distance of the vehicle is reduced according to a second preset time-distance reduction strategy until the current time-distance is a preset minimum time-distance.

[0079] It should be understood that if the target toggle device for detecting the driver is a time-distance reduction toggle device, and the toggle method is short-term toggle, then the vehicle's current time distance is reduced according to the first preset time distance reduction strategy (i.e., time distance decreases by 1 per second); if the target toggle device is a time-distance reduction toggle device, and the toggle method is long-term toggle, then the vehicle's current time distance is reduced to the preset minimum time distance according to the second preset time distance reduction strategy (i.e., time distance decreases by 1 per second), until the vehicle's current time distance no longer decreases.

[0080] Furthermore, in some embodiments, determining the vehicle speed adjustment strategy and / or time-distance adjustment strategy based on the target toggle device and the toggle method includes: if the target toggle device is a time-distance increasing toggle device and the toggle method is short-term toggle, then determining whether the vehicle's current time-distance has increased to a preset maximum time-distance, and if the current time-distance has not increased to the preset maximum time-distance, increasing the vehicle's current time-distance according to a first preset time-distance increasing strategy; if the current time-distance has increased to the preset maximum time-distance, stopping the increase of the current time-distance; if the target toggle device is a time-distance increasing toggle device and the toggle method is long-term toggle, then increasing the vehicle's current time-distance according to a second preset time-distance increasing strategy until the vehicle's current time-distance increases to the preset maximum time-distance.

[0081] The preset maximum time interval can be a threshold set by the user, a threshold obtained through a limited number of experiments, or a threshold obtained through a limited number of computer simulations. Preferably, the preset maximum time interval is set to 5.

[0082] It should be understood that if the driver's target toggle device is detected as a time-distance toggle device, and the toggle method is a short-term toggle, then it is determined whether the vehicle's current time distance has increased to the preset maximum time distance. If the vehicle's current time distance increases to the preset maximum time distance, the increase in the current time distance stops. If the current time distance has not increased to the preset maximum time distance, the vehicle's current time distance is increased according to the first preset time distance increase strategy (i.e., time distance increases by 1). If the driver's target toggle device is detected as a time-distance toggle device, and the toggle method is a long-term toggle, then it is determined whether the vehicle's current time distance has increased to the preset maximum time distance. If the current time distance has not increased to the preset maximum time distance, the vehicle's current time distance is increased to the preset maximum time distance according to the second preset time distance increase strategy (i.e., time distance increases by 1 per second). If the vehicle's current time distance increases to the preset maximum time distance, the increase in the current time distance stops.

[0087] In step S4, the driver assistance system does not respond to the driver's toggle button operation at this time, maintains the vehicle's own operating state, and does not intervene in any vehicle control.

[0088] Step S5: If the pressed toggle device is not a cruise speed increase toggle device, proceed to step S6; if the pressed toggle device is a cruise speed increase toggle device, proceed to step S7.

[0097] Step S14: According to the driver's operating intention, the cruise system setting speed of the driving assistance system is reduced by 5 km / h or 1 km / h, and the driver's operating system response is completed.

[0098] Step S15: Determine whether there is a speed limit sign or speed camera ahead of the road when the driver presses the toggle device. If there is a speed limit sign or speed camera, proceed to step S16; otherwise, proceed to step S17.

[0099] Step S16: Determine whether the current vehicle speed is greater than the speed limit specified by the current road speed limit sign or electronic speed limit when the driver presses the toggle device. If the current vehicle speed is greater than the speed limit, proceed to step S18; if the current vehicle speed is less than the speed limit, proceed to step S19.

[0100] Step S17: According to the driver's operating intention, the cruise system setting speed of the driving assistance system is reduced by 5 km / h or 1 km / h, and the driver's operating system response is completed.

[0101] Step S18: According to the driver's operating intention, within 500ms of pressing the button, first set the cruise system setting speed of the driving assistance system to the speed limit value specified by the speed limit sign or the speed limit specified by the electronic eye; at the same time, reduce the cruise speed by 5KM / H or 1KM / H every second thereafter (subject to actual calibration experience depending on different models, the specific value is not specifically limited); and then execute step S20.

[0102] Step S19: According to the driver's operating intention, reduce the cruise speed by 5 km / h or 1 km / h per second, and simultaneously execute step S20.

[0103] Step S20: Determine whether the cruise control system setting speed of the current driving assistance system has been reduced to the system's preset minimum speed value of 20 km / h (the actual calibration experience shall prevail depending on the different vehicle models, and the specific value is not specifically limited). If it has been reduced to the system's preset minimum speed value, proceed to step S21; if it has not been reduced to the system's preset minimum speed value, proceed to step S19.

[0104] Step S21: Based on the preset minimum speed value of the driving assistance system, the system will no longer reduce the speed or respond to the driver's deceleration request. The driver's operating system response for this time is complete.

[0105] Step S22: When the driver's toggle device is a time-distance reduction toggle device, determine whether the toggle mode is a short-time toggle or a long-time toggle. If the driver's toggle mode is a short-time toggle, proceed to step S23; if the driver's long-time toggle mode is a short-long-time toggle, proceed to step S24.

[0107] Step S24: According to the driver's operating intention, the following distance of the driving assistance system is reduced by 1 per second (the specific value is subject to actual calibration experience depending on different vehicle models and is not covered by this patent); at the same time, step S25 is executed.

[0108] Step S25: Further determine whether the following distance of the current driving assistance system has been reduced to the system's preset minimum following distance value of 1 (the specific value is subject to actual calibration experience depending on different vehicle models). If it has been reduced to 1, proceed to step S26; if it has not been reduced to 1, proceed to step S24.

[0109] In step S26, based on the preset minimum distance value of the driving assistance system, the system no longer reduces the distance and no longer responds to the driver's request to reduce the distance. The driver's operating system response for this time is complete.

[0110] Step S27: When the driver's toggle device is a time-interval toggle device, determine whether the toggle mode is short-term or long-term. If the driver's toggle mode is short-term, proceed to step S28; if the driver's toggle mode is long-term, proceed to step S29.

[0111] Step S28: Determine whether the following distance of the current driving assistance system has increased to the system's preset maximum following distance value of 5 (the actual calibration experience shall prevail for different vehicle models, and the specific value is not specifically limited). If it has not increased to 5, proceed to step S29; if it has increased to 5, proceed to step S30.

[0112] Step S29: According to the driver's operating intention, increase the following distance of the driving assistance system by 1. The driver's operating system response for this time is complete.

[0113] In step S30, based on the preset maximum time distance value of the driving assistance system, the system no longer increases the time distance and no longer responds to the driver's request to increase the time distance. The driver's operating system response for this time is complete.

[0114] Step S31: Determine whether the following distance of the current driving assistance system has increased to the system's preset maximum following distance value of 5. If it has not yet increased to 5, proceed to step S32; if it has already increased to 5, proceed to step S33.

[0116] In step S33, based on the preset maximum time distance value of the driving assistance system, the system no longer increases the time distance and no longer responds to the driver's request to increase the time distance. The driver's operating system response for this time is complete.

[0117] Step S34: When the driver's toggle device is a cruise speed increase toggle device, if the driver's toggle method is a short-term toggle, proceed to step S35; if the driver's toggle method is a long-term toggle, proceed to step S38.

[0118] Step S35: Further determine whether the cruise control system setting speed of the current driving assistance system has been increased to the system's preset maximum speed value of 130 km / h (the actual calibration experience shall prevail depending on the different vehicle models, and the specific value is not specifically limited). If it has not been increased to the system's preset maximum speed value, proceed to step S36; if it has been increased to the system's preset maximum speed value, proceed to step S37.

[0124] In summary, the speed and distance adjustment processing methods of the driver assistance system are integrated into the vehicle's infotainment system or body controller. These methods comprise four functional parts:

[0125] Firstly, when the driving assistance system is activated, the cruise speed of the driving assistance system is adjusted by receiving the operation information of the driver pressing the toggle device, and the system determines whether the driver presses the upper toggle device to increase the cruise speed or the lower toggle device to decrease the cruise speed.

[0126] Secondly, when the driver assistance system is active, it adjusts the following distance of the driver assistance system by receiving the operation information of the driver pressing the toggle device. It determines whether the driver presses the upper toggle device to increase the following distance or presses the lower toggle device to decrease the following distance.

[0127] Furthermore, when the driver assistance system is temporarily disengaged and the driver attempts to increase the cruise speed using the toggle switch, the driver assistance system attempts to resume operation and regain control of the vehicle.

[0128] Finally, when the driver assistance system is activated, and there is a speed limit sign or speed camera ahead, and the vehicle's set cruise speed is greater than the speed limit, if the driver uses the toggle switch to reduce the cruise speed, the driver assistance system will directly reduce the cruise speed to the speed limit.

[0129] This invention provides a method for adjusting the speed and distance of a driving assistance system. When any toggle device is detected to be moved, if the driving assistance system is in a preset active state, the method acquires the target toggle device and the toggle method among multiple toggle devices, and determines the vehicle's speed adjustment strategy and / or distance adjustment strategy based on the target toggle device and the toggle method. The method then adjusts the vehicle's cruising speed according to the speed adjustment strategy and / or adjusts the vehicle's current distance according to the distance adjustment strategy. This solves the problem that the speed and distance adjustment methods in related technologies are limited by the characteristics of the hardware itself and the defects of existing solutions, which cannot fully realize the efficiency and ease of use of speed and distance adjustment in automotive driver assistance systems. On the one hand, the steering wheel toggle device is located behind the steering wheel hood, and it can be used by pressing any finger other than the thumb of the left or right hand without taking the hand off the steering wheel, thus solving the first problem of speed adjustment and the second problem of distance adjustment. The area behind the steering wheel hood has only one toggle device on each side, with independent position and function, which can be easily operated blindly, thus solving the second problem of speed adjustment and the first problem of distance adjustment. The adjustment method only requires pressing the toggle device in the direction of the driver, which is easy to learn and master, thus solving the third problem of speed adjustment and the first problem of distance adjustment.

[0130] This embodiment also proposes a device for adjusting the speed and time distance of a driving assistance system.

[0131] Figure 4 This is a block diagram of the device for adjusting the speed and travel distance of the driving assistance system in this embodiment.

[0132] like Figure 4 As shown, the device 10 for adjusting the speed and distance of the driving assistance system includes: a detection module 100, a judgment module 200, and an adjustment module 300.

[0133] The detection module 100 is used to determine whether the vehicle's driving assistance system is in a preset active state when any toggle device is detected to be toggled; the determination module 200 is used to obtain the target toggle device and toggle method among multiple toggle devices if the driving assistance system is in a preset active state, and determine the vehicle's speed adjustment strategy and / or time-distance adjustment strategy based on the target toggle device and toggle method; the adjustment module 300 is used to adjust the vehicle's cruising speed according to the speed adjustment strategy and / or adjust the vehicle's current time-distance according to the time-distance adjustment strategy.

[0134] Furthermore, in some embodiments, the multiple toggle devices include a cruise speed reduction toggle device, a time interval reduction toggle device, a time interval increase toggle device, and a cruise speed increase toggle device.

[0135] Furthermore, in some embodiments, the toggle method includes short-duration toggle and long-duration toggle, wherein the duration of short-duration toggle is less than a first preset duration, the duration of long-duration toggle is greater than a second preset duration, and the first preset duration is less than or equal to the second preset duration.

[0136] Furthermore, in some embodiments, the determination module 200 is also configured to: if the target toggle device is a cruise speed reduction toggle device, and the toggle method is short-term toggle, then when there is a speed limit requirement in front of the vehicle and the current vehicle speed is greater than the speed limit value corresponding to the speed limit requirement, set the vehicle's cruise speed to the speed limit value corresponding to the speed limit requirement; when there is a speed limit requirement in front of the vehicle and the current vehicle speed is less than or equal to the speed limit value corresponding to the speed limit requirement, reduce the vehicle's current speed according to a first preset deceleration strategy; when there is no speed limit requirement in front of the vehicle, directly reduce the vehicle's current speed according to the first preset deceleration strategy; if the target toggle device is a cruise speed reduction toggle device... The device is a speed-limiting mechanism with a long-duration toggle. When there is a speed limit ahead of the vehicle and the vehicle's current speed is greater than the speed limit, the vehicle's cruising speed is set to the speed limit, and the vehicle's current speed is reduced according to a second preset deceleration strategy until it reaches a preset minimum speed. When there is a speed limit ahead of the vehicle and the vehicle's current speed is less than or equal to the speed limit, the vehicle's current speed is reduced according to the second preset deceleration strategy until it reaches a preset minimum speed. When there is no speed limit ahead of the vehicle, the vehicle's current speed is reduced directly according to the second preset deceleration strategy.

[0137] Furthermore, in some embodiments, the determination module 200 is also used to: if the target toggle device is a time-distance reduction toggle device and the toggle method is short-term toggle, then reduce the current time distance of the vehicle according to the first preset time-distance reduction strategy; if the target toggle device is a time-distance reduction toggle device and the toggle method is long-term toggle, then reduce the current time distance of the vehicle according to the second preset time-distance reduction strategy until the current time distance is the preset minimum time distance.

[0138] Furthermore, in some embodiments, the determination module 200 is also used to: determine the vehicle speed adjustment strategy and / or time distance adjustment strategy based on the target toggle device and the toggle method, including: if the target toggle device is a time distance increasing toggle device and the toggle method is short-term toggle, then determine whether the current time distance of the vehicle has increased to a preset maximum time distance, and if the current time distance has not increased to the preset maximum time distance, increase the current time distance of the vehicle according to a first preset time distance increasing strategy; if the current time distance has increased to the preset maximum time distance, stop increasing the current time distance; if the target toggle device is a time distance increasing toggle device and the toggle method is long-term toggle, then increase the current time distance of the vehicle according to a second preset time distance increasing strategy until the current time distance of the vehicle increases to the preset maximum time distance.

[0139] Furthermore, in some embodiments, the determination module 200 is also configured to: if the target toggle device is a cruise speed increase toggle device and the toggle method is short-term toggle, determine whether the current speed of the vehicle has increased to a preset maximum speed, and if the current speed has not increased to the preset maximum speed, increase the current speed of the vehicle according to a first preset speed increase strategy; if the current speed has increased to the preset maximum speed, stop increasing the current speed; if the target toggle device is a cruise speed increase toggle device and the toggle method is long-term toggle, increase the current speed of the vehicle according to a second preset speed increase strategy until the current speed of the vehicle increases to the preset maximum speed.

[0140] Furthermore, in some embodiments, after determining whether the vehicle's driving assistance system is in a preset active state, the detection module 100 is further configured to: if the driving assistance system is not in a preset active state, determine that the driving assistance system is in a preset temporary deactivation state; if the driving assistance system is in a preset temporary deactivation state, determine whether the cruise speed increase toggle device among the multiple toggle devices has been activated, and when the cruise speed increase toggle device is activated, control the driving assistance system to enter a preset active state; otherwise, maintain the current operating state of the vehicle.

[0141] It should be noted that the foregoing explanation of the method embodiment for adjusting the speed and distance of the driving assistance system also applies to the device for adjusting the speed and distance of the driving assistance system in this embodiment, and will not be repeated here.

[0142] This invention provides a device for adjusting the speed and distance of a driving assistance system. When any toggle device is detected to be activated, if the driving assistance system is in a preset active state, it acquires the target toggle device and its activation method from among multiple toggle devices. Based on the target toggle device and activation method, it determines a vehicle speed adjustment strategy and / or a distance adjustment strategy. The vehicle's cruising speed is adjusted according to the speed adjustment strategy, and / or the vehicle's current distance is adjusted according to the distance adjustment strategy. This solves the problems of inefficiency and ease of use in speed and distance adjustment methods of related technologies, which are limited by hardware characteristics and the shortcomings of existing solutions. The device is position-independent, function-independent, easy to learn and master, and improves the intelligence of vehicle driving.

[0146] Furthermore, the vehicle also includes:

[0147] Communication interface 503 is used for communication between memory 501 and processor 502.

[0148] The memory 501 is used to store computer programs that can run on the processor 502.

[0149] The memory 501 may include high-speed RAM (Random Access Memory) memory, and may also include non-volatile memory, such as at least one disk storage.

[0150] If the memory 501, processor 502, and communication interface 503 are implemented independently, then the communication interface 503, memory 501, and processor 502 can be interconnected via a bus to complete communication between them. The bus can be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, or an EISA (Extended Industry Standard Architecture) bus, etc. The bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 5 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0151] Optionally, in a specific implementation, if the memory 501, processor 502, and communication interface 503 are integrated on a single chip, then the memory 501, processor 502, and communication interface 503 can communicate with each other through an internal interface.

[0152] Processor 502 may be a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or one or more integrated circuits configured to implement this embodiment.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
