A bicycle control device includes an electronic controller that controls a motor, which assists propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor to less than or equal to a limit value upon determining a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to change at least one of the limit value of the output of the motor and a time in which the output of the motor is decreased upon determining the shifting device is performing the shifting action in accordance with at least one of an actuation state of the shifting device in the shifting action and a parameter of the bicycle that is changed by the shifting action performed by the shifting device.

A bicycle control device includes an electronic controller that receives data indicative of a detected gas pressure of a gas chamber of a bicycle component provided to a bicycle. The electronic controller controls an electric component provided to the bicycle in accordance with the detected gas pressure of the gas chamber of the bicycle component. The gas chamber of the bicycle component is configured to maintain a gas in a compressed state.

A bicycle control device that easily maintains the ratio of the assist force generated by a motor to the human drive force input to a bicycle at a predetermined ratio includes an electronic controller that controls a transmission, which is configured to change the transmission ratio of the bicycle, and the motor, which assists propulsion of the bicycle. The electronic controller is configured to control the motor so that the ratio of the assist force generated by the motor to the human drive force inputted to the bicycle becomes equal to the predetermined ratio. The electronic controller is configured to control the transmission in correspondence with at least one of the output torque of the motor and the human drive force to maintain the predetermined ratio.

A bicycle control device is configured to appropriately control a motor. The bicycle control device is provided in a bicycle driving device. A bicycle control device includes an electronic controller that controls a motor, which assists with propulsion of a bicycle. In a case where a traveling speed of the bicycle is less than or equal to a predetermined speed, the electronic controller controls the motor so that the motor assists with propulsion of the bicycle. The predetermined speed is changed in accordance with at least one of a usage environment of the bicycle and a posture of the bicycle.

A bicycle controller includes an electronic control unit that controls a transmission unit and a motor in accordance with a shift request that changes the transmission ratio. If the transmission ratio is changed in multiple steps in accordance with the shift request, then the electronic control unit selectively executes one of first and second shifting operations. In the first shifting operation, the output of the motor is limited and the transmission unit is operated to reach a requested transmission ratio that corresponds to the shift request. In the second shifting operation, the output of the motor is limited and the transmission unit is operated to reach an intermediate transmission ratio of the requested transmission ratio, and after the electronic control unit temporarily reduces the limitation on the output of the motor, the electronic control unit again limits the output of the motor and operates the transmission unit.

If the user of an information processor enters into it a performance request to perform a job and a notification request to notify one or more other information processors of batch processing for the job, this processor transmits the performance and notification requests to a management apparatus. When the management apparatus receives the requests, the apparatus transmits to that processor or those processors a batch m processing notification inviting it or them to transmit to the apparatus a performance request to perform a job. If, within a specified length of time after the notification transmission, the management apparatus receives from that processor or at least one of those processors a performance request to perform a job, the apparatus transmits to an image forming apparatus the jobs which the image forming apparatus is requested to perform. Then, the image forming apparatus performs the jobs by means of batch processing.
