Electronically controlling torque converter in automatic gear box of vehicle

摘要

A control unit (9) receives information concerning engine torque Mm, engine speed nm, turbine speed nt, the selected gear Gnsu and the actual gear Galt and calculates an optimum output torque value Mabsol. Another control unit (7) uses this data to calculate a torque value MKzusoll for the coupling (8). The actual torque value MKzuist of the coupling (8) is fed back to another control unit (5) and compared with the calculated optimum value MKzusoll and the signal current I is corrected.
