Abstract
A bicycle control apparatus is basically provided with a manual drive force detecting device, a rotation state detection device and a controller. The manual drive force detecting device detects a manual drive force. The rotation state detection device detects a parameter relating to crankshaft rotation of a crankshaft. The controller is programmed to control at least one of a driving unit that generates an auxiliary drive force and an electric transmission unit so that the manual drive force and the parameter relating to the crankshaft rotation will be within a prescribed range.
Claims28
A bicycle control apparatus comprising:
- a manual drive force detecting device that detects a manual drive force;
- a rotation state detection device that detects a parameter relating to crankshaft rotation of a crankshaft;
- and
- a controller programmed to control an output of power assisted to a bicycle user by controlling at least one of a driving unit that generates an auxiliary drive force and an electric transmission unit so that the manual drive force and the parameter relating to the crankshaft rotation will both be within a prescribed range of a preset relationship between a crankshaft rotational speed and the manual drive force applied to the crankshaft.
A bicycle control apparatus comprising:
- a manual drive force detecting device that detects a manual drive force;
- a rotation state detection device that detects a parameter relating to crankshaft rotation of a crankshaft;
- and
- a controller programmed to control at least one of a driving unit that generates an auxiliary drive force and an electric transmission unit so that the manual drive force and the parameter relating to the crankshaft rotation will be within a prescribed range, the controller being further programmed to increase the auxiliary drive force upon determining that the manual drive force is greater than the prescribed range and the parameter relating to the crankshaft rotation is in a first range that is within the prescribed range.
A bicycle control apparatus comprising:
- a manual drive force detecting device that detects a manual drive force;
- a rotation state detection device that detects a parameter relating to crankshaft rotation of a crankshaft;
- an operation part;
- and
- a controller programmed to control at least one of a driving unit that generates an auxiliary drive force and an electric transmission unit so that the manual drive force and the parameter relating to the crankshaft rotation will be within a prescribed range, the controller being further programmed to set or change the prescribed range based on at least one of the manual drive force detected by the manual drive force detecting device and the parameter relating to the crankshaft rotation detected by the rotation state detection device upon the operation part being operated during traveling.
