Method and apparatus for controlling a bicycle transmission with combined shift commands
First Claim
1. A bicycle gear shift control apparatus for controlling a gear shift unit that shifts a bicycle transmission among a plurality of gears, wherein the gear shift control apparatus comprises:
- a shift command input that receives shift commands indicating a desired gear shift operation;
a control output that outputs control signals that control the gear shift unit to shift the bicycle transmission;
a gear shift monitor that monitors a progress of a gear shift operation by the gear shift unit;
a gear shift controller operatively coupled to the shift command input, to the control output, and to the gear shift monitor, wherein the gear shift controller receives a shift command and outputs a control signal that controls the operation of the gear shift unit to shift the bicycle transmission to a target gear; and
wherein the gear shift controller modifies the control signal when the gear shift controller receives a second shift command corresponding to a second target gear that differs from a first target gear corresponding to a first shift command and the gear shift operation initiated by the first shift command has not completed.

Abstract
A gear shift control apparatus comprises a shift command input that receives shift commands indicating a desired gear shift operation, a control output that outputs controls signals that control a gear shift unit to shift the bicycle transmission, a gear shift monitor that monitors a progress of a gear shift operation by the gear shift unit, and a gear shift controller operatively coupled to the shift command input, to the control output, and to the gear shift monitor. The gear shift controller receives a shift command and outputs a control signal that controls the operation of the gear shift unit to shift the bicycle transmission to a target gear. The gear shift controller modifies the control signal when the gear shift controller receives a second shift command corresponding to a second target gear that differs from a first target gear corresponding to a first shift command and the gear shift operation initiated by the first shift command has not completed.

11. A method for controlling a bicycle gear shift unit that shifts a bicycle transmission among a plurality of gears, wherein the method comprises the steps of:
-
receiving shift commands indicating desired gear shift operations;
outputting a control signal that controls the gear shift unit to shift the bicycle transmission;
monitoring a progress of a gear shift operation by the gear shift unit; and
modifying the control signal when a second shift command corresponding to a second target gear that differs from a first target gear corresponding to a first shift command is received and the gear shift operation initiated by the first shift command has not completed. - View Dependent Claims (12, 13, 14, 15, 16)
