Abstract
A plurality of sets of sample data points from a vehicle sensor are determined, each set including a predetermined number of consecutive sample data points. Respective differences between pairs of consecutive sample data points in each set are determined. The differences are stored in respective subspaces of one of a plurality of memory spaces of the memory, each memory space in the plurality of memory spaces storing differences of one and only one of the plurality of sets of sample data points. The collected data are restored based on the stored differences in the plurality of memory spaces. A vehicle component is actuated based on the restored data.
Claims20
A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to:
- determine a plurality of sets of sample data points collected from a vehicle sensor, each set including a predetermined number of consecutive sample data points;
- determine respective differences between pairs of consecutive sample data points in each set;
- store the differences in respective subspaces of one of a plurality of memory spaces of the memory, each memory space in the plurality of memory spaces storing differences of one and only one of the plurality of sets of sample data points;
- restore the collected data based on the stored differences in the plurality of memory spaces;
- and
- actuate a vehicle component based on the restored data.
A method, comprising:
- determining a plurality of sets of sample data points collected from a vehicle sensor, each set including a predetermined number of consecutive sample data points;
- determining respective differences between pairs of consecutive sample data points in each set;
- storing the differences in respective subspaces of one of a plurality of memory spaces of the memory, each memory space in the plurality of memory spaces storing differences of one and only one of the plurality of sets of sample data points;
- restoring the collected data based on the stored differences in the plurality of memory spaces;
- and
- actuating a vehicle component based on the restored data.
