Document Type and Number:
Japanese Patent JP6838717
Kind Code:
B2
Abstract:
The present invention provides a malfunction detecting device with which, even if an error exceeding a scope of guarantee occurs in the position or speed of a peripheral object output by a sensor which monitors the periphery of a vehicle, the output from the sensor in which the error exceeding the scope of guarantee has occurred in the position or speed of the peripheral object is detected as abnormal. This malfunction detecting device is characterized in that the malfunction detecting device detects an object using two sensors A, B, and if a difference equal to or greater than a prescribed value arises between state quantities of the detected object, the malfunction detecting device uses standard information relating to the state quantity of the object to determine in which of the two sensors A and B the measurement failure has occurred.
