SYSTEMS AND METHODS FOR SHIFTING MULTI-SPEED TRANSMISSIONS

A method for shifting multi-speed transmissions (110a-110c) of marine propulsion devices (101a-101c) each having a powerhead (102a-102c) and a shift schedule for shifting between first and second gears to transmit torque from the powerhead (102a-102c). The method includes configuring the transmissio...

Zusammenfassung:	A method for shifting multi-speed transmissions (110a-110c) of marine propulsion devices (101a-101c) each having a powerhead (102a-102c) and a shift schedule for shifting between first and second gears to transmit torque from the powerhead (102a-102c). The method includes configuring the transmissions (110a-110c) of leader and follower marine propulsion devices (101a-101c) to shift when shift schedules of the leader and of the follower indicate shift recommendations, respectively. The method further includes receiving a request to shift the transmission (110a-110c) of the leader when the shift schedule of the leader indicates the shift recommendation. The method further includes determining whether conditions are met for the follower to follow the leader in shifting. The method further includes automatically requesting, when conditions are determined to be met for the follower to follow the leader, to shift the transmission (110a-110c) of the follower so as to be coordinated with shifting the transmission (110a-110c) of the leader.
