A vehicle obstacle detection device can relatively increase a distance at which the vehicle obstacle detection device is able to detect an obstacle even when a voltage supplied from a power supply to a sensor fluctuates. The vehicle obstacle detection device includes a sensor that transmits and receives ultrasonic waves, and a controller that instructs the sensor to transmit the ultrasonic waves. The controller compares amplitude of reflected waves received by the sensor with a threshold to determine presence or absence of the obstacle. The controller includes a voltage monitoring unit that detects a power supply voltage. The controller more reduces the threshold as the power supply voltage detected by the voltage monitoring unit is lower.
