  • Patent number: 7652560
    Abstract: A radar device is configured to transmit an electric wave and receives a reflected wave that is generated by a reflection of the electric wave on an object, and to recognize the object is a potential obstacle that is to be hit by the vehicle when a received intensity of the reflected wave thereby is a specified threshold or more. And, the specified threshold has a plurality of preset values. Accordingly, a determination as to whether or not the obstacle detected by the radar device is the potential obstacle to be hit by the vehicle can be accurately made.

  • Patent number: 7504987
    Abstract: In an obstacle detecting control device installed in a vehicle body and includes a millimeter-wave radar detecting an obstacle in front of the vehicle and an operation control portion controlling a bake device and seatbelt pre-tensioner according to detection results of the obstacle by the radar, there are provided a detection frequency determining portion determining that a detection frequency of obstacle by the radar within a specified period of time exceeds a first frequency, an excessive frequency determining portion determining that a frequency of the above determination by the detection frequency determining portion exceeds a second frequency, and an indication portion and a warning buzzer to warn a passenger of a change of radar axis of the radar when the above determination by the excessive frequency determining portion is made.

  • Publication number: 20080079629
    Abstract: There are provided a radar device that transmits a frequency modulation-continuous wave (FM-CW) and outputs an up-beat frequency and a down-beat frequency, a pairing processing section that conducts pairing of the up-beat frequency and the down-beat frequency at specified sampling intervals, a target-object detecting section that detects target objects around the vehicle, obtaining a distance from the vehicle to the target object and a relative speed between the vehicle and the target object based on the up-beat frequency and down-beat frequency that are paired, and a prediction processing section that obtains a prediction data for each target object for a next sampling timing. The pairing processing section conducts the pairing with priority to a specified target object that has a high certainty of the prediction data. Thereby, the pairing of the up-beat and down-beat frequencies can be conducted precisely and quickly.
