DATA ACQUISITION METHOD AND APPARATUS FOR DRIVERLESS VEHICLE
First Claim
1. A data acquisition method for a driverless vehicle, comprising:
- acquiring sensor information from each sensor among at least one sensor of the driverless vehicle, the sensor information comprising;
an importance level, a collection period, and a number of data packets required to be collected per collection period;
selecting a sensor having a highest importance level among the at least one sensor as a first sensor;
selecting at least one sensor other than the first sensor from the at least one sensor based on the importance level of the sensor to form a second sensor set;
acquiring a start time of a current time window, and executing following data processing steps;
executing real-time acquiring and storing operations on data packets collected by each sensor among the at least one sensor after the start time of the current time window;
determining whether any condition in a following condition group is met;
a collection period of the first sensor has elapsed from the start time of the current time window to a current time;
a number of acquired and stored data packets collected by the first sensor has reached the number of data packets required to be collected per collection period of the first sensor, and a number of the acquired and stored data packets collected by each sensor in the second sensor set has reached the number of data packets required to be collected per collection period of the sensor; and
setting the start time of the current time window to the current time in response to determining that any condition in the condition group is met, and continuing executing the data processing steps.

Abstract
The present application discloses a data acquisition method and apparatus for a driverless vehicle. A specific implementation of the method comprises: selecting a sensor having the highest importance level among at least one sensor of the driverless vehicle as a first sensor and at least one sensor other than the first sensor to forma second sensor set; acquiring a start time of a current time window, and executing the following data processing steps: executing real-time acquiring and storing operations on data packets collected by each sensor among the at least one sensor after the start time of the current time window; determining whether any condition in the following condition group is met; and in response to determining that any condition in the condition group is met, setting the start time of the current time window to the current time, and continuing executing the data processing steps. This implementation realizes synchronized storage of the data packets collected by the at least one sensor of the driverless vehicle.
