Abstract
Abstract In a ranging sensor system for a vehicle for calculating a physical data between a subject vehicle and an object on the basis of the time between the transmission of a signal toward the object and the reception of a signal reflected from the object, a first obtained detection data is set as an offset value in an offset value setting circuit. The offset value is subtracted from the detection data in a subtractor, and an output from the subtractor is filtered in a filter circuit. The offset value is added to an output from the filter circuit in an adder to provide a physical data after the filtering. Thus, it is possible to eliminate an error included in detection data, while insuring a responsiveness and a stability.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
129 words
A ranging sensor system for a vehicle for calculating a physical data between a subject vehicle and an object on the basis of the time between the transmission of a signal toward the object and the reception of a signal reflected from the object, comprising: detection means for detecting data representing a physical relationship between the subject vehicle and the object; offset value setting means for setting an initial value of detection data output from the detection means as an offset value; subtracting means for subtracting the offset value from a non-initial value of detection data; filter means for filtering an output from said subtracting means; and adding means for adding the offset value to an output from said filter means to provide a filtered value of physical data.
Claim 2
Dependent Claim
129 words
A ranging sensor system for a vehicle for calculating a physical data between a subject vehicle and an object on the basis of the time between the transmission of a signal toward the object and the reception of a signal reflected from the object, comprising: detection means for detecting data representing a physical relationship between the subject vehicle and the object; offset value setting means for setting an initial value of detection data output from the detection means as an offset value; subtracting means for subtracting the offset value from a non-initial value of detection data; filter means for filtering an output from said subtracting means; and adding means for adding the offset value to an output from said filter means to provide a filtered value of physical data.
Claim 3
Dependent Claim
81 words
A radar sensor system for a vehicle according to claim 1, further comprising memory means for storing a plurality of values of detection data obtained over a predetermined period of time, and determining means for determining, when all values of detection data obtained for less than the predetermined period of time are zero, and when a new value of detection data obtained after said predetermined period of time is not zero, said new value as said initial value of detection data.
