Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a torque filter coefficient determining method according to an embodiment of the present invention, where the torque filter coefficient determining method is applied to an in-vehicle terminal. As shown in fig. 1, the method for determining the torque filter coefficient mainly includes the following steps:
in this embodiment, the vehicle-mounted terminal obtains the current operating parameters of the vehicle, that is, the operating parameters of the relevant components of the vehicle at the current time. Optionally, the current operating parameter of the vehicle includes any one of: vehicle speed parameters, gear parameters and braking parameters. Specifically, the vehicle speed parameter may include speed data acquired by a speed sensor of the vehicle and acceleration data acquired by an acceleration sensor, the gear parameter may include a gear state parameter of the vehicle acquired by a gear-slapping lever of the vehicle and a related device, and the brake parameter may include a brake parameter output by a brake system of the vehicle, and the like. Of course, the operating parameters may also include other parameters associated with the operating state of the vehicle, without limitation.
after obtaining the current operation parameters of the vehicle, the vehicle-mounted terminal determines the attribute values of the current operation parameters, wherein the attribute values can include the attributes such as the risk degree and the occurrence frequency, and the magnitude of the risk degree and the occurrence frequency of the scene corresponding to the current operation parameters in the past driving process are determined according to the attribute values.
After the attribute value of the current operation parameter is determined, the vehicle-mounted terminal can determine the current operation grade of the vehicle according to the attribute value of the current operation parameter. The corresponding relationship between the attribute value and the operation level may be stored in the vehicle-mounted terminal in advance, and the operation level corresponding to the attribute value of the current operation parameter, that is, the current operation level, may be found from the corresponding relationship. The vehicle-mounted terminal can also preset an algorithm, and the attribute values of the current operation parameters are calculated according to the algorithm, so that the corresponding current operation grade can be obtained. Other schemes capable of determining the current operation level of the vehicle according to the attribute value of the current operation parameter are applicable to the embodiment, and are not described again.
And 103, determining a target filter coefficient corresponding to the current operation level.
After the vehicle-mounted terminal determines the current operation grade of the vehicle according to the steps, the corresponding filter coefficient can be determined according to the current operation grade, and the filter coefficient is the target filter coefficient. And the vehicle-mounted terminal carries out filtering processing on the torque signal according to the determined target filtering coefficient, so that the running system of the vehicle can run more smoothly, the vehicle-mounted terminal is more suitable for the current running scene, and the driving safety is ensured.
In the method for determining a torque filter coefficient according to the embodiment of the present invention, the vehicle-mounted terminal determines the corresponding current operation level according to the acquired attribute value of the current operation parameter of the vehicle, and further determines the target filter coefficient corresponding to the current operation level. Therefore, the attribute values of the current operation parameters are integrated, the determined torque filter coefficient is more accurate, the filtering processing effect on the torque signals of the vehicle is better, and the driving safety is facilitated.
On the basis of the above embodiment, before the step of determining the current operation level of the vehicle according to the attribute value of the current operation parameter in step 102, the method further includes:
creating a correspondence between attribute values of the operating parameters of the vehicle and the operating levels of the vehicle;
the step 102 of determining the current operation level of the vehicle according to the attribute value of the current operation parameter includes:
and determining the current operation grade of the vehicle according to the corresponding relation between the attribute value of the operation parameter and the operation grade and the attribute value of the current operation parameter.
In this embodiment, before determining the filter coefficient according to the operation parameter, the vehicle-mounted terminal first creates a corresponding relationship between the attribute value of the operation parameter and the operation level of the vehicle, and then in a specific use process, according to the corresponding relationship and the attribute value of the operation parameter at the current time, the corresponding current operation level can be searched, and then the corresponding target filter coefficient is determined.
In one specific embodiment, the step of creating a correspondence between the attribute value of the operating parameter of the vehicle and the operation level of the vehicle includes:
acquiring attribute values of operating parameters in at least two operating scenes and required torque filter coefficients;
and obtaining the corresponding relation between the attribute value of the operation parameter and the operation grade according to the corresponding relation between the operation grade and the filter coefficient, and the attribute values of the operation parameter and the required torque filter coefficient in the at least two operation scenes.
And the vehicle-mounted terminal establishes a corresponding relation between the attribute values of the operation parameters and the operation state grades according to the relevant operation data in a plurality of operation scenes in the historical driving process. The vehicle-mounted terminal can receive operation data used for referring to historical driving scenes and input by a user according to data in a historical operation scene recorded locally, or can acquire related data in the historical operation scenes from other equipment. Specifically, the relevant operation data of each operation scenario may include the operation parameters under the operation scenario and the torque filter coefficients under the operation scenario.
Further, the step of obtaining the corresponding relationship between the attribute value of the operating parameter and the operating level according to the corresponding relationship between the operating level and the filter coefficient, and the attribute value of the operating parameter and the required torque filter coefficient in the at least two operating scenarios includes:
determining attribute values of the operating parameters and required torque filter coefficients in each operating scene;
and obtaining the corresponding relation between the attribute value of the operation parameter in each operation scene and the operation grade according to the torque filter coefficient and the operation grade.
The vehicle-mounted terminal can calculate the attribute value of the operation parameter in each operation scene and the torque filter coefficient required by each operation scene according to the calculated relevant operation data in the plurality of operation scenes. In addition, the corresponding relation between the torque filter coefficient and the operation grade is also arranged in the vehicle-mounted terminal, so that the vehicle-mounted terminal can obtain the corresponding relation between the attribute value of the operation parameter and the operation grade.
Therefore, after the vehicle-mounted terminal obtains the operation parameter, the attribute value of the operation parameter can be searched, the corresponding operation grade is searched from the corresponding relation between the attribute value of the operation parameter and the operation grade according to the searched attribute value, and the corresponding target filter coefficient is further obtained. The specific implementation process may be as shown in table 1, and the corresponding attribute value, operation level, and filter coefficient are sequentially determined according to the operation parameter.
TABLE 1
In another embodiment, the step of determining the current operation level of the vehicle according to the attribute value of the current operation parameter includes:
determining the current operation scene of the vehicle according to the attribute value of the current operation parameter of the vehicle;
and determining the current operation grade of the vehicle according to the current scene of the vehicle.
In this embodiment, the vehicle-mounted terminal may further obtain the current operation parameter, determine the current operation scene according to the attribute value of the current operation parameter, and then determine the current operation level corresponding to the current operation scene.
For example, the current operating parameters of the vehicle may include the current operating speed, lateral acceleration, longitudinal acceleration, and normal acceleration of the vehicle;
and determining the current running scene of the vehicle according to the current running speed, the lateral acceleration, the longitudinal acceleration and the normal acceleration of the vehicle, wherein the running scene comprises any one of acceleration steering, deceleration steering, acceleration straight running and deceleration straight running.
In the present embodiment, the determination scheme of the operation level is described in conjunction with a specific scene during the vehicle running. The vehicle-mounted terminal can acquire the acceleration of the vehicle in the transverse direction, the longitudinal direction and the normal direction in real time, and the current running scene of the vehicle can be determined according to the acceleration and the change value in the three directions. For example, if the lateral acceleration becomes large and the longitudinal acceleration decreases, it is determined that the current operation scene of the vehicle is a decelerating steering. On the contrary, if the lateral acceleration is increased and the longitudinal acceleration is increased, the current running scene of the vehicle is determined to be acceleration steering.
In addition, under the condition that the operation levels determined according to the attribute values of different operation parameters are not unique, the final operation level can be determined according to the operation level with high risk degree, so that the driving safety of the vehicle is ensured as much as possible. For example, in a certain scenario, if the operation speed is low, the risk level is determined to be low, and if the operation speed is high, the risk level is determined to be high, for example, a high-speed turn may cause a rollover risk. If the occurrence frequency is high, the determined operation level is uncertain because deceleration and turning are common operations which often occur, and the operation level corresponding to the higher danger level is determined.
In another specific embodiment, the attribute values include a risk level and an appearance frequency level;
the risk level grade comprises a high risk grade and a low risk grade, and the occurrence frequency grade comprises a high frequency grade and a low frequency grade;
the current operation grade of the vehicle is a weighted value of the risk degree grade and the appearance frequency grade of the current operation parameter.
In this embodiment, the attribute values are determined to include a risk level and an appearance frequency level, and after determining the risk level and the appearance frequency level of the operation parameter, the corresponding operation level may be obtained by performing weighted summation. The setting scheme of the weight of the risk degree level and the occurrence frequency level may be set according to specific situations, for example, the weight of the risk degree level is set to be greater than the occurrence frequency level, and other setting schemes may also be applied to this embodiment, and are not described in detail.
