Human Cancellation
The human cancellation parameter makes detection less likely when a pedestrian enters the
detection area. Adjust this after adjusting the detection sensitivity and making sure that target
vehicles are fully detected.
The detection response time and human cancellation rate have the relation shown in the figure
below. In normal cases, use with sensitivity level 1.
9-7
The presence detection timer starts calibration regularly, regardless of the detection status.
This prevents continuing incorrect detection by the sensor when the ambient environment
changes.
