摘要： 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.

摘要： 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.

摘要： 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.
