An indicator data output device, including a storage unit storing vehicle identification data and indicator data, an output unit outputting the stored indicator data, a vehicle usage amount data-obtaining unit obtaining the vehicle identification data and vehicle usage amount data, and an indicator data-updating unit obtaining the vehicle usage amount data and indicator differential data corresponding to an amount of increase in the indicator data calculated based on the vehicle usage amount data, and updating the stored indicator data. The vehicle usage amount data includes at least one of first and second indicators that increase as the vehicle is used. The second indicator indicates a number of times of a third indicator satisfying a predetermined condition, and is dimensionless with respect to all of a plurality of vehicle status dimensions. Each of the first and third indicators is a dimensional quantity with respect to at least one of the plurality of vehicle status dimensions.

Indicator data output device and indicator data output method

A battery-assisted bicycle includes a driving unit that increases an assist ratio and provides a smooth assist control that does not make a rider feel uncomfortable. The driving unit includes a crankshaft to which pedals are to be connected, a crank rotation detector that detects rotation of the crankshaft, and an assist control stopping unit programmed to stop an assist control in response to the rotation of the crankshaft detected by the crank rotation detector.

Driving unit and battery-assisted bicycle

A battery-assisted bicycle includes a driving unit that accurately detects a failure in each of a torque detector, a crank rotation detector, and a motor rotation detector. The driving unit includes a crankshaft to which pedals are to be connected, a motor rotation detector that detects rotation of an electric motor, a torque detector that detects a torque generated at the crankshaft, a crank rotation detector that detects rotation of the crankshaft, and a sensor failure detector that detects a failure in at least one of the motor rotation detector, the torque detector, and the crank rotation detector based on detection results from the motor rotation detector, the torque detector, and the crank rotation detector.

A driving unit and a battery-assisted bicycle include a stopping assist control without making a rider feel uncomfortable. The driving unit includes a crankshaft to which pedals are to be connected, a torque detector that detects a torque generated at the crankshaft, and an assist control stopping unit that stops an assist control based on an amplitude of a torque detected by the torque detector while the crankshaft rotates in a prescribed rotation angle range.

A user information input structure that inputs user information, a memory structure that stores user's bearing information as robot's bearing pattern, and a regenerating structure that regenerates the pattern based on the information input to the user information input structure. A behavior selection and determination structure for selecting and deciding behaviors based on user information, a user information recognition structure for recognizing a user, a memory structure for storing the recognized user information, a calculating structure for comparing the recognized user information with the stored user information to calculate user recognition, and a compensating structure for compensating a selection and determination method in the behavior selection and determination structure in accordance with the calculated user recognition. An actuator for driving a robot, a detection structure for detecting user information and environment information, a feelings generation structure for generating artificial feelings for a robot based on the detecting user and environment information, and a behavior determination structure for determining behaviors by the robot based on the generated artificial feelings, wherein the behavior determination structure controls the actuator so that a resistance acted on the robot may be changed on tactile information the user has applied to the robot.
