The invention discloses a proximity sensor (1) comprising at least one detecting unit (10) of at least one obstacle (40) and a control unit comprising receiving means (22) of first and second parameters (P1, P2) representative of the detecting unit and of features of the obstacle (40). The control unit (20) is further responsible for generation of detection signals (S, S1, Si, Sj) of the obstacle (40), as a function of the first and second representative parameters (P1, P2) and of third representative parameters (P3) of the detected obstacle (40). |

1. A proximity sensor (1) for detecting an obstacle or target (40) for vehicles and operative self-propelled equipment, said sensor (1) comprising:
I: at least one detecting unit (10) of at least one obstacle (40), said detecting unit (10) comprising:
a: a transmitting module (11) configured to transmit at least one transmission signal (S, S1, Si, Sj) to at least one obstacle (40);b: a receiving module (12) configured to receive at least one reflected signal (R, R1, Ri, Rj) from said at least one obstacle (40), wherein said at least one reflected signal (R, R1, Ri, Rj) is representative of an occurred proximity detection of said at least one obstacle (40); II: a control unit (20) comprising:
a: receiving means (21) of:
i: first parameters (P1) representative of characteristics of said obstacle (40) to be detected;ii: second parameters (P2) representative of characteristics of said detecting unit (10);iii: third parameters (P3) representative of characteristics of said detected obstacle (40);b: a first generation module (203) configured to generate at least one main transmission signal (S), as a function of said parameters (P1, P2), said main signal (S) being generated for said at least one detecting unit (10);c: a first calculation module (201) configured to calculate said third parameters (P3), representative of characteristics of the detected obstacle (40), obtainable from a reflected signal (R) reflected by said main transmission signal (S);d: a second generation module (204) configured to generate at least one additional transmission signal (S1) as a function of said parameters (P1, P2, P3), said at least one additional signal (S1) being generated for said at least one detecting unit (10);e: a comparison module (202), connected to said first calculation module (201), and configured to compare the respective calculated distances (d, d1, di) with each other, which distances are obtainable from said respective reflected signals (R, R1, Ri);wherein said comparison module (202) is configured to transmit a calculated-distance value (d1, di) to said transmitting module (11), as a function of said additional reflected signal (R1, Ri), if said calculated distance (d1, di) is different from said first calculated distance (d, d1);wherein the value of calculated distance (d, d1) as a function of said additional reflected signal (R1, Ri) is obtained from an additional transmission signal (S1, Si) transmitted after said main transmission signal (S);wherein said receiving means (21) comprises a memory (21a) and said comparison module (202) is configured to generate a selection signal (Se) for said memory (21a) if said calculated distance (d1, di) is coincident with said first calculated distance (d, d1). |
