Abstract:
1. An obstacle detecting apparatus comprising: a warning device: a plurality of sensors for detecting an obstacle; and a control device to which the plurality of sensors are connected through a bus, wherein the control device is coupled to the warning device, the control device including the warning device is activated if the communication error determination means determines that the communication with any of the sensors is impossible, the communication error determination means sets in advance, as the error determination time period, a preset first error determination time period in the case of the first communication with the plurality of sensors and a preset second error determination time period in the case of communication with the plurality of sensors after the first communication with the plurality of sensors is normally performed, the first error determination time period and the second error determination time period are set so as to be different from each other, and the first error determination time period is set by the communication error determination means to be shorter than the second error determination time period.
