Circuit/System Description

The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The advanced parking assist control module supplies reference voltage to the object sensors via the reference voltage circuit and provides ground via the low reference circuit. The advanced parking assist control module triggers the sensors in a sequential loop. After each sensor transmits, the advanced parking assist control module uses the sensor echo received though the signal circuit to calculate the distance and position of an object.
