Detailed Description
To further clarify the technical measures and effects taken by the present application to achieve the intended purpose, the following detailed description of preferred embodiments, methods, steps, structures, features and effects according to the present application will be made with reference to the accompanying drawings. The following detailed description is not to be taken in a limiting sense, and the terminology used herein and the accompanying drawings are for the purpose of describing particular embodiments only and are not intended to be limiting of the application.
First embodiment
Fig. 1 is a flowchart illustrating a method for adaptive driving mode according to a first embodiment, and referring to fig. 1, the method for adaptive driving mode of the present embodiment includes the following steps:
and step 110, acquiring the driving condition of the vehicle.
In this embodiment, the driving condition of the vehicle includes at least one of a current driving mode, a vehicle state, an accelerator opening degree, and road condition information, which may reflect a current condition of the vehicle. The vehicle-mounted terminal collects vehicle data through a vehicle-mounted sensor, wherein the vehicle data comprises an accelerator opening, a brake signal, a vehicle speed, acceleration and the like, and the brake signal, the vehicle speed, the acceleration and the like are used for reflecting the current vehicle state. In addition, the surrounding environment of the vehicle can be acquired through the vehicle-mounted camera, and the map navigation information can be acquired through the vehicle-mounted navigator, so that the road condition information can be acquired.
And 120, switching the driving mode of the vehicle according to the driving condition.
Generally, the driving modes of the vehicle include a sporty driving mode (Sport mode), a comfortable driving mode (Comfort mode), and an Eco driving mode (Eco mode).
The comfortable driving mode refers to daily driving, an operation mode of pursuing comfort, stability and fuel consumption and energy conservation, and when the driving mode is in the comfortable driving mode, the automobile suspension is soft, has good stable passing performance, and is slowly started and stopped. When the driving mode is in a motion driving mode, the vehicle can increase the rotating speed to keep enough torque and quickly start and stop, so that the performance of the vehicle is completely highlighted, and a rider can obviously feel that the vehicle backs up; and the suspension is hard, the supporting force is strong, the accelerator response is rapid, the air intake of the engine is increased, the acceleration is very fast, and the oil consumption is also increased greatly. When the driving mode is in the economic driving mode, the vehicle reduces the reaction rate of power output, reduces a lot of unnecessary fuel injection, and enables the rotating speed to be smoother, so that the sensitivity of the reaction of the accelerator is reduced, the power is relatively moderate, even if a driver deeply steps on the accelerator, the driver basically does not feel the feeling of pushing back caused by acceleration inertia, and the oil consumption is saved.
The driving mode of vehicle is switched according to the driving condition, and different driving modes have different driving experiences. Through automatic switch driving mode, improve the driving comfort, let the different driving of user experience feel.
In the first embodiment, the switching the driving mode of the vehicle according to the driving condition in step 120 specifically includes:
analyzing preset driving modes excited by the driving conditions according to the excitation conditions of different preset driving modes;
and switching the driving mode of the vehicle according to the analysis result.
The preset driving mode is a driving mode which can be used in a vehicle in a preset mode, such as a driving mode (Sport mode), a comfortable driving mode (Comfort mode), an economic driving mode (Eco mode) and the like, and the excitation condition of the preset driving mode is used for limiting the condition that the current driving condition can excite the corresponding preset driving mode. In this embodiment, the excitation condition of the preset driving mode includes at least one of a driving mode condition, a vehicle state condition, an accelerator opening threshold, and a road condition information condition, which is different according to different preset driving modes. The vehicle-mounted terminal analyzes at least one preset driving mode correspondingly excited in the current driving mode, the vehicle state, the accelerator opening degree and the road condition information in the driving working condition according to the excitation condition of the preset driving mode. And then, the vehicle-mounted terminal switches the driving mode of the vehicle according to the analysis result, so that the driving mode is automatically switched, and the driving comfort is improved.
The excitation condition of the preset driving mode may be set when the vehicle leaves a factory, set by a user, or automatically generated during use of the vehicle. In an embodiment, the preset driving mode triggering condition is automatically generated during the use of the vehicle, and the method of this embodiment may further include:
calculating the driving style of the current user according to the driving data of the vehicle;
determining at least one accelerator opening threshold value for exciting at least one preset driving mode according to the driving style;
and generating and storing excitation conditions of different preset driving modes according to at least one accelerator opening threshold value.
The step of calculating the driving style of the current user according to the driving data of the vehicle specifically comprises the following steps:
presetting a plurality of vehicle speed intervals;
obtaining the driving style of the current user according to the vehicle speed characteristics and the acceleration characteristics corresponding to the plurality of vehicle speed intervals in the driving data, wherein the driving style comprises the following steps: soft, comfortable and radical.
In an application scenario, the vehicle-mounted terminal acquires a vehicle speed signal, an accelerator signal and an acceleration signal within a preset time length through a sensor to acquire driving data of a vehicle within the preset time length, wherein the preset time length can be one week, one month, half year or one year. Dividing the vehicle speed interval into 0-20km/h, 20km/h-40km/h, 40km/h-70km/h and more than 70km/h, carrying out cluster analysis, and taking the arithmetic average value of acceleration values with the acceleration of more than 0.05g in different vehicle speed intervals to obtain the acceleration behavior characteristics of the driver. And finally, obtaining whether the driving style of the current user is soft, comfortable or aggressive by using the vehicle speed characteristic and the acceleration characteristic through a K-means algorithm. It will be appreciated that the driving style of the user may be varied and the driving style data of the user may be updated and adjusted according to the driving data.
In practical implementation, the excitation conditions for automatically switching the driving modes are obviously distinguished under different driving styles.
For example, when the driving style is "aggressive", the accelerator opening threshold value for activating the sport driving mode is determined to be more than 40% according to the "aggressive" driving style, and when the vehicle-mounted terminal is to generate the "aggressive" driving style, the activation condition for switching to the sport driving mode includes the accelerator opening threshold value being more than 40% and is stored in the vehicle-mounted terminal.
For another example, when the driving style is "soft", the accelerator opening threshold for activating the sport driving mode is determined to be greater than 80% according to the "soft" driving style, and when the in-vehicle terminal is to generate the "soft" driving style, the activation condition for switching to the sport driving mode includes the accelerator opening threshold being greater than 80% and is stored in the in-vehicle terminal. Compared with the situation that the driving style is 'aggressive', under the 'soft' driving style, the user needs larger accelerator opening degree to automatically switch to the sport driving mode, namely, the sport driving mode is not easy to switch.
During actual implementation, the step of analyzing the preset driving mode corresponding to the driving condition according to the excitation condition of the different preset driving modes may specifically include:
acquiring excitation conditions of different preset driving modes;
correcting the excitation conditions of different preset driving modes according to the current vehicle state;
and analyzing the preset driving mode excited by the driving working condition according to the corrected excitation condition.
However, the accelerator opening threshold value in the excitation condition of the different preset driving modes is not limited to the correction of the accelerator opening threshold value, and may be, for example, an accelerator opening change rate threshold value or the like.
In an application scene, the vehicle is currently in a motion driving mode, the vehicle is in a state of enough torque, quick start and quick stop, the accelerator responds quickly and accelerates quickly, and the vehicle speed can be obviously changed by slightly stepping on the accelerator. And the vehicle-mounted terminal correspondingly corrects and switches the accelerator opening threshold of the driving mode, and reduces the accelerator opening threshold in the excitation condition so as to adapt to the excitation condition of the state of the vehicle in the current driving mode.
In another application scenario, the vehicle is currently in an economic driving mode, the sensitivity of the response of the accelerator is reduced, the power is moderate, and the accelerator needs to be stepped deeply to generate obvious speed increase. And the vehicle-mounted terminal correspondingly corrects and switches the accelerator opening threshold of the driving mode, and increases the accelerator opening threshold in the excitation condition so as to adapt to the excitation condition of the state of the vehicle in the current driving mode.
The vehicle-mounted terminal corrects the excitation condition of the preset driving mode according to the real-time vehicle state, so that the vehicle-mounted terminal can more swiftly recognize the driving mode suitable for the current vehicle state, and is more intelligent, the switching of the driving mode is more in line with the current actual driving, and a user has better driving experience.
In the following, the preset driving modes including the sport driving mode, the comfortable driving mode and the economy driving mode are taken as examples, and the excitation conditions of different preset driving modes are listed.
Wherein, the excitation condition corresponding to the motion driving mode comprises at least one of the following conditions:
the method comprises the following steps that the required torque in the vehicle state is larger than a first torque threshold value, the accelerator pedal opening degree change rate is larger than a preset change rate threshold value, and the accelerator opening degree is larger than a first accelerator opening degree threshold value; the road condition information is that the road gradient is greater than a preset gradient threshold value.
In an application scenario, the excitation conditions corresponding to the sport driving mode are that the required torque is greater than a first torque threshold, the accelerator pedal opening change rate is greater than a preset change rate threshold, and the accelerator opening is greater than a first accelerator opening threshold, where the first accelerator opening threshold is, for example, 80% according to the driving style. When the vehicle is in high-speed driving, the vehicle-mounted terminal acquires that the opening change rate of an accelerator pedal of a user is larger than a preset change rate threshold value through a sensor, detects that the opening of the accelerator pedal is larger than 80%, and the torque required by the user is larger than a first torque threshold value, meets the excitation condition of a motion driving mode, and the vehicle automatically enters the motion driving mode.
In another application scenario, the excitation condition of the sport driving mode is that the road condition information is that the road gradient is greater than a preset gradient threshold, where the preset gradient threshold is 10%. When a vehicle enters a road with a slope and lasts for a certain time such as 1 second, the vehicle-mounted terminal acquires the slope of the current road according to the information of the slope sensor, and when the absolute value of the slope is greater than the slope threshold value by 10%, the vehicle-mounted terminal automatically switches driving to a motion driving mode.
Wherein the excitation condition corresponding to the comfortable driving mode comprises at least one of the following:
when the driving mode is the sport driving mode, the accelerator opening is smaller than a second accelerator opening threshold value; when the driving mode is the economic driving mode, the accelerator opening is larger than a third accelerator opening threshold value, and the required torque in the vehicle state is larger than a second torque threshold value; the accelerator opening is smaller than the second accelerator opening threshold value and the required torque in the vehicle state is smaller than the third torque threshold value; the road condition information is a curve; and when the driving mode is the sport driving mode, the accelerator opening is smaller than the second accelerator opening threshold value, the overtaking state in the vehicle state is overtaking, and the required torque is smaller than the third torque threshold value.
In practical implementation, the excitation condition corresponding to the comfortable driving mode in the sport driving mode prestored in the vehicle-mounted terminal includes that the accelerator opening is smaller than a second accelerator opening threshold, where the second accelerator opening threshold is, for example, 60% according to the driving style. When the vehicle is currently in a motion driving mode, the vehicle-mounted terminal acquires that the opening degree of an accelerator is smaller than 60%, and then the driving mode is switched to a comfortable driving mode; when the driving mode is the economic driving mode, the excitation condition corresponding to the comfortable driving mode comprises that the accelerator opening is larger than a third accelerator opening threshold and the required torque in the vehicle state is larger than a second torque threshold, wherein the third accelerator opening threshold is 30% according to the driving style, for example, when the vehicle is in the economic driving mode at present, the vehicle-mounted terminal obtains that the accelerator opening is larger than 30% and the required torque of the user is larger than the second torque threshold, and then the driving mode is automatically switched to the comfortable driving mode.
In an application scene, the excitation condition corresponding to the comfortable driving mode is that the road condition information is a curve. And in the driving process of the vehicle, according to the navigation information, acquiring that the current vehicle is about to enter a curve, and automatically switching the driving mode to a comfortable driving mode by the vehicle-mounted terminal.
In another application scenario, when the driving mode is the sport driving mode, the excitation conditions corresponding to the comfortable driving mode are that the accelerator opening is smaller than a second accelerator opening threshold, and the overtaking state in the vehicle states is overtaking and the demanded torque is smaller than a third torque threshold, where the second accelerator opening threshold is, for example, 60% according to the driving style. When a user runs in the motion driving mode and the vehicle-mounted terminal detects that a vehicle overtakes behind, the current accelerator opening is smaller than 60% and the torque required by the user is smaller than the third torque threshold value, and the driving mode is automatically switched to the comfortable driving mode.
Wherein, the excitation condition corresponding to the economic driving mode comprises at least one of the following conditions:
the accelerator opening is smaller than a fourth accelerator opening threshold value; the vehicle state is constant-speed cruising; the vehicle state is that the vehicle speed keeps the preset duration unchanged; the road condition information is traffic jam; the vehicle state is that the distance between the vehicle and the front vehicle is less than a preset distance; the road condition information is a speed-limited road section, and the vehicle speed is greater than the speed-limited value in the vehicle state;
in an application scene, the vehicle-mounted terminal detects that the current accelerator opening is smaller than a fourth accelerator opening threshold, and automatically switches the driving mode to the economic driving mode according to the driving style if the fourth accelerator opening threshold is 20% for example; when the vehicle is in constant-speed cruising or constant-speed running, the vehicle automatically switches the driving mode to the economic driving mode
In another application scenario, the excitation condition corresponding to the economic driving mode is that the road condition information is traffic jam. The vehicle-mounted terminal acquires congestion information through navigation or recognizes that the distance between the vehicle and the front vehicle is smaller than a preset distance through radar, and then recognizes that the vehicle is about to enter a traffic congestion area in advance. The vehicle driving mode will automatically switch to the economy driving mode depending on the conditions of the activation of the economy driving mode.
In another application scenario, the excitation condition corresponding to the economic driving mode is that the road condition information is a speed-limited road section and the vehicle speed is greater than the speed-limited value in the vehicle state. The vehicle-mounted terminal acquires the speed limit sign through the camera so as to obtain the speed limit information of the current road section, or acquires the speed limit prompt of the current road section through the speed limit prompt of the navigation. And when the current vehicle speed is greater than the speed limit value acquired by the vehicle-mounted terminal, automatically switching the vehicle driving mode to the economic driving mode.
For the same driving style, sequentially reducing a first accelerator opening threshold value, a second accelerator opening threshold value, a third accelerator opening threshold value and a fourth accelerator opening threshold value; the first torque threshold, the third torque threshold, and the second torque threshold decrease in sequence. When the values of various thresholds are determined, the following rules are followed: under the same driving style, the switching to the sport driving mode is the most difficult, a larger throttle opening is needed, the switching to the economy driving mode is the simplest, a smaller throttle opening is needed, and the switching to the comfortable driving mode is positioned between the sport driving mode and the economy driving mode; for different driving styles, the more aggressive the driving style, the simpler the switching to the sporty driving mode, the harder the switching to the economical driving mode, and the more comfortable the switching to the comfortable driving mode are located between the two.
In an embodiment, the method for adaptive driving mode further includes:
and after the driving mode is switched, switching the display atmosphere of the instrument into the display atmosphere matched with the current driving mode.
The vehicle-mounted controller sends a driving mode through the CAN bus, realizes the linkage of the driving mode of the whole vehicle, displays different atmospheres through different driving modes, and enables a driver to experience different driving feelings.
By the mode, the driving mode can be controlled by analyzing the driving working condition, the driving mode can be automatically switched, and the operation burden of a driver is reduced, so that the driving comfort and convenience are improved; and a driving mode selection device can be cancelled, so that the cost is effectively reduced.
