Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as “weave.” A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.

A stroke sensor system includes a tubular vehicle-body-side member, a tubular vehicle-wheel-side member, and a displacement obtainer. The tubular vehicle-body-side member is disposed at a vehicle body side. The tubular vehicle-wheel-side member is coupled to the vehicle-body-side member on a vehicle wheel side and movable in an axial direction of the vehicle-body-side member relative to the vehicle-body-side member. At least one of the members is a conductor. Another one of the members includes a coil. The displacement obtainer includes a capacitor electrically coupled to the coil and constituting an LC oscillation circuit that outputs an oscillation waveform when the members move relative to each other. The displacement obtainer digitizes the oscillation waveform to obtain a reshaped waveform, divides a frequency of the reshaped waveform by a frequency division ratio to obtain a frequency-divided waveform, and uses the frequency-divided waveform to obtain a displacement by which the members move relative to each other.

A holder for a two-wheeler accessory, in particular for a two-wheeler lock, comprises a base body by which a contact surface is defined which the two-wheeler accessory contacts when it is received in the holder and one or more pivot clips that each comprise a holding limb and a lever limb and are pivotable about a pivot axis beyond a dead center between a release position and a securing position in order to allow a receiving of the two-wheeler accessory in the holder or a removal of the two-wheeler accessory from the holder in the release position and to block the two-wheeler against a removal from the holder in the securing position by means of the holding limb when said two-wheeler accessory is received in the holder.

One embodiment of an electric convenience vehicle (ECV) may include a frame, a plurality of wheels configured to support and move the frame, a user support member supported by the frame, a steering mechanism disposed toward a front portion of the ECV, a motor configured to cause at least one wheel to be propelled forward, propelled backward, or to remain in a fixed position, a throttle, when activated in a first position, may cause the motor to propel the wheel(s) in a forward direction, when activated in a second position, may cause the motor to propel the wheel(s) in a reverse direction, and a control and communications unit (CCU) disposed in front of the user support member, and configured to control operations of the motor.

A motorcycle cooling system that includes a controller, a sensing member for sensing at least one environmental condition and that is in communication with the controller, and a fan assembly. The fan assembly includes a shroud having an inner surface that defines a central opening extending therethrough, and a fan in airflow communication with the central opening. The fan is configured to move air through the central opening from a first end to a second end of the shroud. The fan is in communication with the controller. The controller turns the fan on when a first environmental condition is sensed by the sensing member and the controller turns the fan off when a second environmental condition is sensed by the sensing member.

A torque and power measuring device corresponding to the non-drive side cyclist leg, comprising a hollow shaft connecting the two bicycle crank arms with strain sensors arranged in the shaft surface. These sensors are connected to an electronic control unit housed inside the shaft, to which are also connected other different sensors to measure a plurality of interesting quantities (pedaling cadence, crank arm angular position . . . ). This electronic control unit picks the sensor signals up, stores them and performs pre-programmed software operations to later wirelessly output the result signals towards a receiving device for analysis and/or storage them, by means of an antenna located outside the shaft and anchored to the outer surface of the jointed crank arm with the shaft.

A straddle-type vehicle comprises a vehicle body frame; a heavy weight vehicle member mounted on a vehicle body; a support member fastened to the vehicle body frame to support the heavy weight vehicle member; and a vehicle body behavior sensor which detects a behavior of the vehicle body, and the vehicle body behavior sensor is mounted on the support member.
