摘要
A sensor unit includes a sensor interface coupled to a number of sensors and a host interface coupled to a host system utilized to autonomously drive the vehicle. The sensor unit further includes sensor control modules corresponding to the sensors. Each sensor control module includes delay time control logic, delay adjustment logic, and a trigger signal generator. The delay time control logic is to receive a pulse time adjustment (PTA) value from the host system. The delay adjustment logic is to receive a trigger time adjustment (TTA) value from the host system. The delay adjustment logic is to modify timing of at least a portion of the pulses of a pulse signal based on the PTA value and the TTA value. The trigger signal generator is to generate a trigger signal based on the modified pulse signal and to transmit the trigger signal to a corresponding sensor.
