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 parking assist



control module supplies 8 V to the object sensors via the 8 V reference circuit and provides ground via the low reference circuit. The parking assist



control module triggers the sensors in a sequential loop. After each sensor transmits, the parking assist control module uses the sensor echo



received through the signal circuit to calculate the distance and position of an object.
