摘要： An electric bicycle (10), which is a vehicle including a crank pedal (79) which receives an input from a leg of a rider, a rear wheel (78) to which power input to the crank pedal (79) is transmitted, and a motor (M) which outputs power to be transmitted to the rear wheel (78), is switchable between an EAB driving state as a first driving state in which the rear wheel (78) is driven by at least the power input to the crank pedal (79), and an EV driving state as a second driving state in which the rear wheel (78) is driven by the power of the motor (M) alone.

摘要： A torque sensor for a bicycle includes a coil. The torque sensor may include a support that is disposable around a device of the bicycle, such that the support and the device of the bicycle are separated by an air gap. The torque sensor may also include an excitation coil supported by the support, and a sense coil supported by the support at a distance away from the excitation coil in an axial direction of the support. The excitation coil is configured to induce a voltage and/or current in the sense coil via the device of the bicycle when the support is disposed around the device of the bicycle. The induced voltage is related to a torque in the device.

摘要： A power switching structure includes an input shaft (10), a detection shaft sleeve (20) fit over the input shaft (10), an assisting power assembly (40), and an output assembly (30) selectively drivable by the input shaft (10) and the assisting power assembly (40). The output assembly (30) includes first and transmission sleeves (31, 35) rotatably mounted to the input shaft (10). The assisting power assembly (40) includes a power member (41) rotatably mounted to the second transmission sleeve (35). A one-way bearing (37, 42) is arranged between the first and second transmission sleeves (31, 35) and the power member (41). An output member (38) is mounted on the second transmission sleeve (35). A micro-motion static frictional force is induced between the first and second transmission sleeves (31, 35) and the input shaft (10) to allow the detection shaft sleeve (20) to directly and accurately measure a torque value of the input shaft (10). The one-way bearing (37, 42) arranged between the first and second transmission sleeves (31, 35) and the power member (41) allows for selection among sources of power.

摘要： An electric bicycle (10) includes: a sleeve (26) to which power for driving the electric bicycle (10) is input; a rear wheel (78); and a power transmission mechanism (T) that transmits the power input to the sleeve (26) to the rear wheel (78). The electric bicycle (10) determines an abnormality of the power transmission mechanism (T) or prevents or prohibits driving performed by using the power transmission mechanism (T) based on a reference composite gear ratio (Rc1) of the power transmission mechanism (T) acquired at a first time and current composite gear ratio (Rc2) of the power transmission mechanism (T) acquired at a second time subsequent to the first time.
