[0041] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 FIG. 1 is a hardware structure diagram of a terminal of the vehicle driving mode recommendation method of this embodiment. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data, wherein processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1The structure shown is only for illustration and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0042] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the vehicle driving mode recommendation method in the present embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0043] The transmission device 106 is used to receive or send data via a network. The above network includes a wireless network provided by the communication provider of the terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0044] In this embodiment, a vehicle driving mode recommendation method is provided. Figure 2 is a flow chart of the vehicle driving mode recommendation method of this embodiment. Figure 2 As shown, the process includes the following steps:

[0045] Step S210, obtaining the current environment information, driving status information and chassis information of the target vehicle.

[0046] Among them, the current environmental information can be information about natural factors and spatial positions that characterize the environment in which the target vehicle is located. The current environmental information may include, but is not limited to: the location information of the target vehicle, the weather information of the area in which the target vehicle is located, and the navigation map information of the target vehicle. In particular, the location information, weather information, navigation map information, etc. of the target vehicle can be monitored through the telematics & connectivity antenna module (TCAM) connected to the vehicle information system, and the above current environmental information can be sent to the central domain control (CSC) through communication with the CSC.

[0047] The driving state information may be a state of vehicle components that characterizes the driving process of the target vehicle. The driving state information may include, but is not limited to: vehicle speed, slip information, tire speed, steering wheel angle information, intelligent driving information, engine torque information, engine status, etc. Among them, the vehicle speed, slip information, and tire speed of the target vehicle can be monitored by the brake control module (BCM for short), and the steering wheel angle information of the target vehicle can be monitored by the power steering control module (PSCM for short). The engine monitoring module (ACL) monitors the engine torque information and engine status. Then, the above-mentioned BCM, PSCM, and ACL send the information they have collected to the CSC respectively. In addition, the high-performance acceleration computer of the CSC can also monitor information such as intelligent driving, and the user experience computer of the CSC can also monitor the driver's status.

[0048] Chassis information may include slope information, wheel speed information, wading information, underwater wading depth, wheel status, chassis suspension height, etc. The zone controller (Zone Controller Tail) monitors chassis information such as suspension height and slope information of the target vehicle. ZCT sends the collected information to CSC.

[0049] In this way, information collection of different dimensions can be achieved in this step. Among them, data collection can be achieved based on multi-dimensional perception methods such as vehicle network perception and intelligent driving perception. For example, vehicle network perception is formed based on weather information, map information and data collected by the camera in the car. Intelligent driving perception is formed through lidar recognition and camera recognition.

[0050] Step S220, identifying the terrain where the target vehicle is located according to the current environment information, driving state information and chassis information to obtain a terrain recognition result.

[0051] The CSC can determine the terrain where the target vehicle is currently located based on the various types of data received. Specifically, the current environment information, driving state information, and chassis information can be analyzed according to different pre-set terrain conditions to obtain a terrain recognition result. The terrain recognition result can indicate the comparison result of the current environment information, driving state information, and chassis information with various comparison thresholds or value ranges set in the corresponding terrain conditions.

[0052] Step S230, determining a recommended driving mode for the target vehicle according to the terrain recognition result.

[0053] The driving mode may include a power driving mode and a chassis mode of the vehicle. According to the terrain recognition result, the terrain where the target vehicle is located is determined, thereby determining the recommended driving mode of the target vehicle. For example, when it is determined that the target vehicle is in snow, the snow mode pre-set for the snow terrain can be determined as the recommended driving mode for the target vehicle; when it is determined that the target vehicle is in sand, the sand mode pre-set for the sand terrain can be determined as the recommended driving mode. This will not be described in detail.

[0054] In addition, different driving modes can provide users with different driving perceptions. For example, the comfort mode can focus on the dynamic impact capacity of the suspension to achieve a more stable overhead form, which is suitable for driving on unpaved twisted roads, unpaved mountain roads or "V"-shaped roads. Let the standard mode focus on dynamic performance, which is suitable for driving on urban elevated roads, highway elevated roads, cement roads and urban bridge roads. The soothing mode adjusts the chassis with the rear passengers as the center, imitates the power characteristics of a fuel engine, reduces the degree of motion sickness, ensures the dynamic balance of the vehicle, and improves the riding comfort of passengers, so that it can be suitable for driving on highways, provincial roads and cement roads. Afterwards, the recommended driving mode that adapts to the current terrain of the target vehicle is output to the user for confirmation through the Center Stack Display (CSD).

[0055] A variety of different driving modes can be configured in current vehicles for user experience. In existing related technologies, users often select the desired driving mode, and through interaction with the vehicle system, the vehicle is controlled to adjust to the driving mode selected by the user. When the user has a shallow understanding of the driving mode and selects a driving mode that does not match the current terrain, it will affect the performance of the vehicle. In addition, the user can choose whether to turn on the recommendation function of the above vehicle mode. For example, the user uses the touch steering wheel to adjust, or the CSD touch screen chooses to turn on the recommendation function of the vehicle driving mode, so as to recommend a suitable driving mode for the target vehicle according to the terrain of the target vehicle.

[0056] In view of the problem that the related art cannot actively recommend driving modes to users, this embodiment identifies the terrain of the vehicle according to the user's driving characteristics, driving scenes and chassis information through the above steps S210 to S230, and then implements targeted power driving mode and chassis comfort mode according to the terrain. Without the need for users to manually select driving modes, the vehicle's handling and stability under different driving conditions can be improved, thereby enhancing safety. When adjusting the driving mode, the recommended driving mode can be switched to through user-perceivable methods, such as multi-dimensional perception methods such as power, chassis, steering and braking.

[0057] Exemplarily, the following table shows the vehicle parameters of various driving modes provided in this embodiment. As shown in the following table, the parameter values ​​corresponding to the drive, suspension height, continuously controlled damping (CDC), steering, active stabilizer bar, anti-lock braking system (ABS), traction control system (TCS), electronic stability system (ESP), energy recovery and braking corresponding to different driving modes may be different. The map in the drive is the absolute pressure sensor of the intake manifold; the medium, low and high in the table can be different values ​​set for the corresponding vehicle parameter items; the parameter n (for example, parameters 1, 2, 3, 5, 7, 8 in the table) can be different parameter values ​​pre-set for the active stabilizer bar. Similarly, normal parameters, sport parameters, slippery parameters, rock parameters, grass parameters, muddy parameters, sandy parameters, deep snow parameters, etc. can also be different parameter values ​​pre-set for ABS, TCS, and ESP. For example, the ABS slip rate of the rock parameter is increased, the TCS braking is enhanced, and the torque reduction is weakened; the TCS braking of the wading parameter is enhanced and the torque reduction is weakened. The optional corresponding to the energy recovery can be expressed as an optional form of energy recovery. Braking This parameter determines the optional pedal feel. "One box" refers to the brake-by-wire system, and CST refers to the vehicle stability control system.

[0058]

[0059] In the above steps S210 to S230, the current environment information, driving state information and chassis information of the target vehicle are obtained; the terrain where the target vehicle is located is identified according to the current environment information, driving state information and chassis information to obtain a terrain identification result; and the recommended driving mode of the target vehicle is determined according to the terrain identification result. It is possible to determine the recommended driving mode corresponding to the target vehicle based on terrain identification, thereby realizing active recommendation of the driving mode.

[0060] In one embodiment, based on the above step S230, determining the recommended driving mode of the target vehicle according to the terrain recognition result may specifically include:

[0061] When the terrain recognition result meets multiple preset terrain conditions, the recommended driving mode is determined from multiple driving modes based on the mode priorities corresponding to the various terrain conditions. Among them, there may be different types of data collected above, which meet different terrain conditions respectively. For example, the wiper activation is determined according to the wiper activation state in the driving state information of the target vehicle, and when the current rainfall is greater than the preset medium rain rainfall threshold value and the ambient temperature is less than 0 degrees Celsius in combination with the weather information in the current environmental information, the terrain recognition result indicates that the target vehicle meets the terrain conditions of the snow, and it is determined that the target vehicle is driving on the snow. On this basis, if according to some other information of the target vehicle, such as the slope within the preset time is greater than the preset slope threshold, and the speed is greater than or equal to the preset speed threshold. At this time, the target vehicle will meet the snow terrain conditions and the mountain road terrain conditions at the same time. Therefore, according to the mode priorities corresponding to the snow terrain conditions and the mountain terrain conditions, the recommended driving mode can be determined from the snow mode corresponding to the snow and the mountain mode corresponding to the mountain.

[0062] Among them, the highest or top-ranked driving modes can be selected according to the priority of the mode and output to the user as recommended driving modes. The driving modes corresponding to all terrain conditions that the terrain recognition result meets, together with the mode priority, can also be output to the user as recommended driving modes. When multiple matching driving modes are output to the user, the user can select the most desired driving mode from them to drive. In this way, by narrowing the optional range of driving modes or directly determining a single most matching driving mode, the driving performance of the vehicle can be improved and safety hazards can be avoided.

[0063] The mode priority can be divided in advance according to the needs of the actual application scenario. For example, the comfort mode can be set as the default driving mode, and the mode priority of other driving modes can be manually set according to the common vehicle scenarios. The above-mentioned description of the driving mode recommendations of the snow mode and the mountain mode is only an example and does not constitute a limitation on the specific implementation method. In addition, the setting of different terrain conditions can also be determined by those skilled in the art according to the needs of the actual application scenario, and this embodiment does not make specific limitations on this.

[0064] Specifically, in one embodiment, when the terrain recognition result satisfies multiple preset terrain conditions, determining a recommended driving mode from multiple driving modes based on the mode priorities corresponding to the various terrain conditions may include:

[0065] The driving mode corresponding to the terrain condition with the highest mode priority is determined as the recommended driving mode for the target vehicle.

[0066] In this embodiment, when it is determined that the terrain recognition result meets multiple preset terrain conditions, the driving mode corresponding to the terrain condition with the highest mode priority is determined as the recommended driving mode for the target vehicle. Therefore, when recommending a driving mode, this embodiment can provide the user with the driving mode with the highest performance and the most matching driving condition of the current target vehicle.

[0067] Additionally, in one embodiment, the driving modes include one or more of a rock mode, a sand mode, a snow mode, a mud mode, a grass mode, a mountain road mode, a wading mode, and a sports mode. This embodiment sets corresponding driving modes for different terrains that the vehicle may travel on, and can maximize the terrain range covered by the driving modes.

[0068] In one embodiment, based on the above step S220, the terrain where the target vehicle is located is identified according to the current environment information, driving state information and chassis information to obtain a terrain identification result, which may include:

[0069] Determine whether the current environment information, driving status information and chassis information meet the corresponding terrain conditions respectively; and determine the terrain recognition result of the target vehicle according to the judgment result.

[0070] Corresponding terrain conditions can be set for different terrains. For example, for the wading mode, the corresponding terrain conditions are set as follows: the wading detection function is activated, the vehicle speed is within the preset wading speed range, and the wading depth is greater than the preset depth (e.g. 8 cm). When the driving state information and chassis information of the target vehicle meet the terrain conditions corresponding to the wading mode, the terrain recognition result of the target vehicle is confirmed to meet the wading terrain conditions, and then it is determined that the target vehicle is in the wading terrain.

[0071] It is understandable that the data involved in terrain determination may be different for different terrains. For example, the above-mentioned wading determination mainly involves chassis information. For slippery terrain determination, driving status information (such as whether the wipers are turned on), current environmental information (weather, temperature), etc. may be involved. This embodiment determines the terrain recognition result of the target vehicle based on terrain condition determination, which can improve the accuracy of terrain recognition.

[0072] Additionally, in one embodiment, the vehicle driving mode recommendation method may further include:

[0073] Output the recommended driving mode to the user; in response to the user's confirmation operation of the recommended driving mode, control the target vehicle to adjust to the recommended driving mode. The recommended driving mode can be output to the user through a vehicle-mounted display screen such as CSD, and then in response to the user's confirmation of the recommended driving mode, control the target vehicle to drive in the recommended driving mode. This embodiment can realize active recommendation of driving modes and realize driving mode confirmation interaction with the user, thereby improving user experience.

[0074] Figure 3 is a flowchart of a method for recommending a vehicle driving mode in some embodiments, such as Figure 3 As shown, the vehicle driving mode recommendation method includes the following steps:

[0075] Step S301, obtaining the current environment information, driving status information and chassis information of the target vehicle.

[0076] Step S302, respectively judging whether the current environment information, driving state information and chassis information meet the corresponding terrain conditions; and determining the terrain recognition result of the target vehicle according to the judgment result.

[0077] Step S303: when the terrain recognition result satisfies a plurality of preset terrain conditions, determining the mode priorities respectively corresponding to the plurality of preset terrain conditions.

[0078] Step S304: Determine, among the mode priorities corresponding to the plurality of preset terrain conditions, the driving mode corresponding to the terrain condition corresponding to the highest mode priority as the recommended driving mode for the target vehicle.

[0079] Figure 4 Schematic diagram of mode priorities corresponding to terrain conditions in some embodiments, such as Figure 4 As shown, the terrain with mode priority one (highest) may include: snow, rock, deep snow, sand, mud, grass (or gravel). The vehicle may be determined to be in snow or deep snow based on the wiper being activated, the rainfall being greater than moderate rain, and the ambient temperature being less than 0 degrees Celsius; or the vehicle may be determined to be in the corresponding terrain based on the terrain conditions corresponding to rock, sand, mud, grass (or gravel) being met.

[0080] Mode priority 2 is wading terrain. The terrain conditions of wading terrain may be that the wading detection function is activated, the vehicle speed is greater than a pre-calibrated wading vehicle speed lower limit (the unit may be kilometers per hour (kph)), less than or equal to 15kph, and the wading depth is greater than a preset depth value (e.g., 8 cm).

[0081] Mode priority three is slippery terrain. The terrain conditions for slippery terrain are that the front wiper is activated, the rainfall is greater than or equal to the preset 4 mm, and the duration is greater than 120 seconds, and the ambient temperature is greater than or equal to 4 degrees Celsius; or, according to the wheel vibration detection result and the tire slip state, it meets the preset slippery state; or the road surface water sensor detects that the road surface water state is slippery.

[0082] Mode priority four is mountain terrain. The terrain conditions of mountain terrain are that the slope signal is credible and the slope signal is greater than the preset mountain road arc threshold, the duration is greater than the preset mountain road mode duration, and the vehicle speed is greater than or equal to the preset mountain terrain vehicle speed.

[0083] Mode priority five may include sports terrain, soothing terrain or economic terrain, wherein the terrain condition of sports terrain is that the accelerator pedal (AccPed) opening change rate (rate) is greater than the preset first opening change threshold (percent per second), and the accelerator pedal opening is greater than 70%, and the duration is greater than the preset sports mode duration.

[0084] The terrain conditions for economic terrain are that the number of drivers and passengers is less than the preset 3, there are no passengers in the second row, the accelerator pedal opening is greater than or equal to 5% and less than or equal to 20%, and the duration is greater than the preset economic mode duration.

[0085] The terrain conditions for soothing terrain are that the number of drivers and passengers is greater than or equal to 3, and the accelerator pedal opening is greater than or equal to 5% and less than or equal to 20%, and the duration is greater than the preset soothing mode duration; or, there are passengers in the back row, and the accelerator pedal opening is greater than or equal to 5% and less than or equal to 20%, and the duration is greater than the preset soothing mode duration.

[0086] Among them, in the soothing mode, when it is detected that the number of drivers and passengers is greater than or equal to 3, and the change rate of the accelerator pedal opening is greater than the preset second opening change threshold, or there are passengers in the back row and the change rate of the accelerator pedal opening is greater than the preset third opening change threshold; or the change rate of the accelerator pedal opening is greater than or equal to 30% and less than or equal to 60%, and the duration is greater than the preset comfort time, the comfort mode is confirmed as the recommended driving mode.

[0087] In economy mode, when it is detected that the change rate of the accelerator pedal opening is greater than the preset fourth opening change threshold; or the change rate of the accelerator pedal opening is greater than or equal to 30% and less than or equal to 60%, and the duration is greater than the preset comfort time, the comfort mode is confirmed as the recommended driving mode (this part is not shown in the figure).

[0088] In the economic mode, if the target vehicle is detected in a congested section and the speed is less than 20kph, and the speed drops from more than 10kph to less than 10kph more than 3 times within 1 minute, the soothing mode is confirmed as the recommended driving mode. After switching to the soothing mode, if the target vehicle is detected in a non-congested section, the economic mode is confirmed as the recommended driving mode.

[0089] In sport mode, when it is detected that the rate of change of the accelerator pedal opening is greater than the preset fifth opening change threshold; or the rate of change of the accelerator pedal opening is greater than or equal to 30% and less than or equal to 60%, and the duration is greater than the preset comfort time, the comfort mode is confirmed as the recommended driving mode.

[0090] In mountain road mode, when it is detected that the slope signal is unreliable; or the slope is less than the preset slope threshold and the duration is greater than the preset comfort time, the comfort mode is confirmed as the recommended driving mode.

[0091] In the mountain road mode, when various data of the vehicle meet the terrain conditions corresponding to the slippery terrain, the slippery mode is confirmed as the recommended driving mode.

[0092] In slippery mode, when the terrain conditions corresponding to slippery terrain are no longer met, comfort mode is confirmed as the recommended driving mode.

[0093] In wading mode, when the wading detection function is not activated; or the vehicle speed is greater than or equal to 30kph, and the wading depth is less than 2cm, confirm that comfort mode is the recommended driving mode.

[0094] The above-mentioned confirmation method of the recommended driving mode and the allocation of mode priority are only examples. Those skilled in the art may also select other methods for setting according to the requirements of the actual application scenario, and this embodiment does not specifically limit this.

[0095] It can also be understood that the above-mentioned lower limit of wading speed, mountain road curvature threshold, mountain road mode duration, mountain road terrain speed and each opening change threshold are calibration values, which can be pre-calibrated according to the actual vehicle condition, such as vehicle weight, body structure and other information, and this embodiment does not make specific limitations on this.

[0096] Figure 5 is a data collection schematic diagram of this embodiment, such as Figure 5As shown, weather information and map information can be collected through the Internet of Vehicles; graphic information around the vehicle can be collected through the perception system, and radar data can be detected through the radar in the perception system; and chassis information such as slope information, wheel speed, inertial measurement unit (IMU) measurement information, wading information, underwater detection information, and wheel status can be collected through other vehicle sensors. Among them, the terrain and topography are extracted based on the map information, the surface information of the objects around the vehicle is extracted based on the graphic information, the road surface information is extracted based on the wheel speed and IMU measurement information, and the motor status is extracted based on the wheel status. Based on the above information, terrain detection is implemented to determine the recommended driving mode. Finally, the recommended driving mode that can be confirmed by the user is sent to the actuator node to control the vehicle to drive in the recommended driving mode.

[0097] Figure 6 FIG. 1 is a schematic diagram of the interaction between various components of a vehicle according to this embodiment. Figure 6 As shown, the vehicle information system connects to the antenna module to send information such as current and future road curvature, predicted traffic speed, current and future road type, current and future road inclination, GNSS (GPS position, altitude, vehSpd) and vehicle power map to the central domain control basic computer; the vehicle brake system control module sends wheel speed, sliding state, vehicle speed, slope, etc. to the central domain control basic computer, and the central domain control basic computer sends the setting information of the electronic stability control system (ESC) to the vehicle brake system control module. The steering control module sends information such as steering angle and steering speed to the central domain control basic computer. The central domain control basic computer sends steering assist level information to the steering control module.
