Object detection apparatus
First Claim
1. An object detection apparatus mounted to a vehicle and included in a driver assistance system for performing a driver assistance function based on a distance to an object, the object detection apparatus being arranged to detect the distance to the object and comprising:
- a transceiver that repeatedly transmits a wave as an ultrasonic wave and receives a reflection wave of the transmission wave reflected by an object;
a transmission controller that controls the transceiver to transmit the transmission wave;
a distance calculator that calculates a distance to the object, based on a time interval from a moment the transceiver transmits the wave to a moment the reflection wave is received; and
a transmission timing controller that controls timing at which the transmission controller controls the transmission wave to be transmitted, wherein;
the transmission timing controller inserts at least one type of temporary waiting time between a transmission/reception period in which the transceiver transmits the transmission wave and receives the reflection wave and a next transmission/reception period, in response to a predetermined crosstalk identification condition being established based on the distance to the object; and
the crosstalk identification condition is a condition for determining whether it is necessary to identify an occurrence of crosstalk.

Abstract
An object detection apparatus is arranged to detect the distance to the object and includes: a transceiver repeatedly transmitting a wave as an ultrasonic wave and receives a reflection wave of the transmission wave; a transmission controller controlling the transceiver to transmit the transmission wave; a distance calculator calculating a distance to the object, based on a time interval from a moment when the transceiver transmits the wave to a moment when the reflection wave is received; and a transmission timing controller controlling timing at which the transmission controller controls the transmission wave to be transmitted. Moreover, the transmission timing controller inserts at least one type of temporary waiting time between a transmission/reception period in which the transceiver transmits the transmission wave and receives the reflection wave and a next transmission/reception period, when a predetermined crosstalk identification condition is established based on the distance to the object.
