Device and method for transmission control

摘要

Control device for a transmission unit (10) comprising a clutch (15) and a gear shift (17) which are coupled respectively to a first and a second actuator unit (19, 21) in order to operate the actuation of the clutch and the selection and engagement/disengagement of the gears. The device comprises a transmission control circuit (24) in which a main microprocessor (44) formulates control signals for the first and second actuator unit (19, 21) and an auxiliary microprocessor (46) determines a state of malfunctioning of the main microprocessor (44) in order to transfer the control of the transmission unit (10) to the auxiliary microprocessor (46) in the event of a fault.
