Abstract
A plurality of ultrasonic sensors are configured such that search ultrasonic waves transmitted from the respective ultrasonic sensors have mutually different characteristics that are mutually distinguishable. A transmission timing setting unit is configured to set a transmission timing of transmitting the search ultrasonic wave for each of the ultrasonic sensors, such that the plurality of ultrasonic sensors transmit the respective search ultrasonic waves at respective transmission timings that are mutually different. The transmission timing setting unit is configured to set a delay time between a first transmission timing, which is a transmission timing of the first ultrasonic sensor, and a second transmission timing, which is a transmission timing of the second ultrasonic sensor, with the delay time being determined based on a positional relationship between the first ultrasonic sensor and the second ultrasonic sensor.
