Electronic control apparatus for an electric drive system, the electric drive system electronic drive unit and electric drive system

摘要

The electronic control unit (2) central unit (7) set point and really value (W ^*, W) receives at the time of normal operation, then electric current set point (I ^*) it seeks, electric current set point (I ^*) central unit (7) transmits in electronic drive unit (3). Drive unit (3) central unit (13) receiving electric current set point (I ^*), then the power switch (15) the control signal of for the sake of (A ^*) seeking, the power switch (15) it outputs these signals. Power source (U) it is connected with that, the electric motor (4) electric current set point (I ^*) according to. At the time of supervision operating, you inspect whether or not the electronic control unit (2) central unit (7), the electric motor (4) there is a safe condition. When the electric motor (4) there is no safe condition, in order the electric motor (4) power source (U) to be cut off securely, central unit (7) the 1st cutout gear (12) and the cutoff signal (A1 and A2) transmits in drive unit (3). Furthermore, the electronic control unit (2) central unit (7) information of inspection (P) it occurs at least at the time of supervision operating, information of inspection (P) transmits in drive unit (3). Drive unit (3) central unit (13), the cutoff signal (A2) it is transmitted in drive unit (3) at the time of supervision operating, and high how, information of inspection (P) is transmitted in drive unit (3) and high how, you inspect whether or not and information of inspection (P) is regular. When making error central unit (13) the 2nd cutout gear (16) through, the electric motor (4) power source (U) it cuts off.
