1. A sensor triggering system for an autonomous vehicle (AV), the sensor triggering system comprising:
- a memory that stores instructions for operating a plurality of sensors of the AV; and
one or more processors executing the instructions, causing the sensor triggering system to;
detect a first sensor pulse from a pulse generator of the AV;
in response to detecting the first sensor pulse, determine a first codeword from a first memory address of a lookup table based on a current memory index pointing to the first memory address in the lookup table; and
selectively trigger the plurality of sensors based on the first codeword stored at the first memory address.

Abstract
A sensor triggering system for a sensor apparatus including a plurality of sensors. The system detects a first sensor pulse and determines a memory address of a lookup table based on the first sensor pulse. In response to the first sensor pulse, the system selectively triggers one or more of the plurality of sensors based at least in part on a codeword stored at the first memory address. For example, the codeword may comprise a number of bits such that each bit of the codeword indicates an activation state for a respective one of the plurality of sensors.

10. A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of an autonomous vehicle (AV), cause the one or more processors to:
-
detect a first sensor pulse from a pulse generator of the AV; in response to detecting the first sensor pulse, determine a first codeword from a first memory address of a lookup table based on a current memory index pointing to the first memory address in the lookup table; and selectively trigger a plurality of sensors of the AV based on the first codeword stored at the first memory address. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An autonomous vehicle (AV) comprising:
-
acceleration, braking and steering systems; a pulse generator; a plurality of sensors; and an AV control system comprising one or more processors and a memory that stores a set of instructions, wherein the set of instructions, when executed by the one or more processors, cause the AV control system to; detect a first sensor pulse from the pulse generator; in response to detecting the first sensor pulse, determine a first codeword from a first memory address of a lookup table based on a current memory index pointing to the first memory address in the lookup table; and selectively trigger the plurality of sensors of the AV based on the first codeword stored at the first memory address. - View Dependent Claims (20)
