As shown in fig. 2, the method may include the steps of:
in step 201, the running state information of the vehicle is acquired.
The operation state information includes working parameters and an operation scene, where the working parameters include one or more combinations of a vehicle speed, a gear, and a steering wheel angle, and optionally, the working parameters may be obtained from various sensors or processing units currently operated by the vehicle, for example, the determination of the vehicle speed, the vehicle speed information may be obtained from a speed sensor for detecting the vehicle speed, or the vehicle speed information may be obtained from a monitoring module for detecting the vehicle operation state in real time; the gear can be determined by using the actual position point of the current gear selecting and shifting shaft detected by the sensor for detecting the gear, or the gear information can be acquired from the monitoring module for detecting the vehicle running state in real time.

And 202, deactivating or activating part of the vehicle control model according to the operation scene.
The number of the vehicle control models may be plural.
Specifically, the vehicle may operate in different operating scenarios, and the vehicle control models required for vehicle operation may be different in different operating scenarios.
In one scenario, the vehicle operation scenario is cruising, which means that a vehicle is currently in a scenario that the vehicle is cruising at a certain speed, so that a vehicle control model for cruising can be started, and the vehicle control model for parking and leaving required by a parking and leaving scenario repellent to cruising can be stopped, so that partial resources of the vehicle are released, the operation of the vehicle control model which is operated is fully met under the condition that system resources are insufficient, and the effect of automatic operation of the vehicle is improved.
In another scenario, the vehicle operation scenario is a garage exit, which means that the vehicle leaves from a fixed parking space, so that the vehicle control model for parking, cruising and parking space detection can be disabled, and the vehicle control model for garage exit is enabled to release the resources of the vehicle, meet the operation of the operated vehicle control model, and improve the automatic operation effect of the vehicle.
In another scenario, the vehicle operation scenario is parking, and since the parking is to park the vehicle in a fixed parking space, the vehicle does not need to be controlled to operate subsequently, so that the vehicle control model for parking needs to be started, and other vehicle control models need to be stopped, so that the resources of the vehicle are released, the operation of the operated vehicle control model is met, and the automatic operation effect of the vehicle is improved.
And 203, according to the working parameters and/or the running scenes of the vehicle, improving the processing frequency of part of the vehicle control models and reducing the processing frequency of the rest of the vehicle control models to obtain the target frequency of the corresponding vehicle control models.
In practical application, when the vehicle runs, the corresponding running scene and/or working parameters of the vehicle are changed, so that the required operating frequencies of the plurality of vehicle control models included in the vehicle are different, according to the preset fixed working frequency, part of the vehicle control models cannot meet the performance requirement of vehicle operation, the working frequency of part of the vehicle control models is possibly set higher, which causes waste, that is, the resources cannot be reasonably allocated, in this embodiment, according to the working parameters and/or the operation scenes of the vehicle, the processing frequency of some vehicle control models is increased and the processing frequencies of the remaining vehicle control models are reduced to obtain the target frequency of the corresponding vehicle control model, so that each vehicle control model can work at a reasonable frequency, reasonable utilization of resources is realized, and the running effect of the vehicle is improved.
