Abstract
The present disclosure discloses a dormancy controlling method for an on board computing platform, a device and a readable storage medium, which relate to the field of autonomous driving in computer technology. A specific implementation is: determining a dormancy level corresponding to the on board computing platform; and controlling, according to the dormancy level, operating states of at least one processor and an external device controlled by the at least one processor in the on board computing platform.
Claims14
A dormancy controlling method for an on board computing platform, comprising:
- determining a dormancy level corresponding to the on board computing platform;
- and
- controlling, according to the dormancy level, operating states of at least one processor and an external device controlled by the at least one processor in the on board computing platform;
- wherein the determining a dormancy level corresponding to the on board computing platform comprises:
- detecting a duration that the on board computing platform has not been operated since a vehicle is started;
- and
- determining the dormancy level corresponding to the on board computing platform by comparing the duration with preset time thresholds, and different dormancy levels correspond to different preset time thresholds;
- wherein the preset time thresholds comprise a first time threshold, a second time threshold, and a third time threshold that are sequentially increased in duration, wherein the larger a time threshold is, the higher a dormancy ratio of the at least one processor in the on board computing platform in the corresponding dormancy level is;
- and
- the dormancy level comprises a first-level dormancy, a second-level dormancy and a third-level dormancy in which the dormancy ratio of the at least one processor in the on board computing platform increases sequentially.
A dormancy controlling apparatus for an on board computing platform, comprising:
- a processor;
- and
- a memory communicatively connected to the processor;
- wherein, the memory stores instructions executable by the processor, and the instructions are executed by the processor to enable the processor to:
- determine a dormancy level corresponding to the on board computing platform;
- and
- control, according to the dormancy level, operating states of at least one processor and an external device controlled by the at least one processor in the on board computing platform;
- wherein the processor is further enabled to:
- detect a duration that the on board computing platform has not been operated since a vehicle is started;
- and
- determine the dormancy level corresponding to the on board computing platform by comparing the duration with preset time thresholds, and different dormancy levels correspond to different preset time thresholds;
- wherein the preset time thresholds comprise a first time threshold, a second time threshold, and a third time threshold that are sequentially increased in duration, wherein the larger a time threshold is, the higher a dormancy ratio of the at least one processor in the on board computing platform in the corresponding dormancy level is;
- and
- the dormancy level comprises a first-level dormancy, a second-level dormancy and a third-level dormancy in which the dormancy ratio of the at least one processor in the on board computing platform increases sequentially.
