PURPOSE:To shorten the required for signal generation and simplify the constitution by forming a virtual sensor to a box shape and generating coordinate signals of the sensor with hardware. CONSTITUTION:A virtual sensor 1 is assumed to have a box shape and is provided with a front sensor 11 and left-right sensors 12 and 13. A direction angle theta, a width W, a length L, and reference coordinates x0 and y0 of the sensor 1 can be changed from the external. When the output request of the sensor occurs, data theta, W, L, x0, and y0 are inputted. For example, when the angle thetais quantized by 16 directions, a quantizing means 2 outputs an area signal SA and a quantizing angle signal, and a generating means 3 determines the timing of the output generation of each sensor, and a holding means 7 holds signals x0 and y0 for a certain time to obtain reference coordinate positions x1 and y1 of the sensor 11 and sends them to an adding means 8. The means 8 adds signals xi and yi and signals xd and yd from a code converting means 6 respectively, and the means 8 and a sensor distinguishing means 9 output a sensor classification signal S in accordance with signals (x) and (y) and individual timings. |
