An electric pedelec bottom bracket drive includes a drive unit, a drive controller, and an ambient temperature detector. The drive unit includes a drive unit housing, a drive motor arranged therein, and a housing temperature sensor which measures a housing temperature. The drive controller supplies electrical drive energy to the drive motor and includes a housing temperature control module which is connected to the housing temperature sensor and which controls an electrical drive energy to not exceed a housing limit temperature. The ambient temperature detector is arranged to detect an air temperature outside of the drive unit housing and is connected to the housing temperature control module. The housing temperature control module limits a maximum electrical drive energy as a function of the air temperature when the housing temperature measured by the housing temperature sensor is above a control intervention limit temperature which is below the housing limit temperature.

An object detection system for a saddle-type vehicle is provided. The system comprises an object detection unit configured to detect an object, wherein the object detection unit is provided on a handlebar which is rotatable to a body of the vehicle; an inclination detection unit configured to detect an inclination of a saddle-type vehicle; a steering angle detection unit configured to detect a steering angle of the handlebar to the body; and a position specification unit configure to specify a position of the object detected by the object detection unit, and correcting the position so that the inclination detected by the inclination detection unit is upright and the steering angle of the handlebar detected by the steering angle detection unit is directed straight.

The present disclosure is directed to lean angle indication for motorcycles. The disclosure provides a motorcycle lean angle indication device that is operationally configured to be attached to a motorcycle and contact a surface that a motorcycle is traveling upon when the motorcycle realizes a target lean angle when executing a turning maneuver.

An orientationally flexible bump sensor is disclosed. The system includes at least one bump sensor mounted to a vehicle, the at least one bump sensor comprising at least two axes of measurement. A computer processor is configured to evaluate the at least two axes of measurement to determine which axis of the at least two axes of measurement has a highest magnitude vector and determine a gain value to cause the highest magnitude vector to be approximately 1g. The computer processor will assign the gain value to the axis with the highest magnitude vector, such that the gain value is applied to each measurement generated by the axis with the highest magnitude vector.

A self-balancing enclosed motorcycle includes a platform base, a seat, a first wheel and a second wheel, a rear cabin, a door component and a gyroscope system. The gyroscope system includes a housing, a gyroscope sensor, a calculation device, an electrical coding device, a microprocessor, a servomotor, a vertical corrective rod movably extended from the servomotor, a first balancing assembly and a second balancing assembly. The first balancing assembly is mounted in the housing to engage with the vertical corrective rod. The second balancing assembly mounted in the housing at an opposite side of the first balancing assembly to engage with the vertical corrective rod. The vertical corrective rod is normally retained in a substantially vertical orientation with respect to the platform base.

Systems and methods for ensuring safe gripping or locking and release of a cyclist's shoe by a bicycle pedal are disclosed. The system may comprise a computing device, one or more sensors for detecting change of velocity, one or more sensors for detecting a change of angle of the bicycle, and a pedal with one or more retractable members. The retractable member may be configured to grip or lock in a cyclist's shoe by extending to interlock with a portion or a cavity of the cyclist's shoe, or to release the cyclist's shoe by retracting on receiving a command from the computing device based on inputs from the one or more sensors.

An approach is provided for determining vehicle maneuver events. The approach, for example, involves determining sensor data from a sensor of a device associated with a vehicle. The sensor data includes a maneuver parameter represented using a device frame of reference. The approach also involves transforming the maneuver parameter from the device frame of reference to an Earth frame of reference. The approach further involves automatically detecting a maneuver event of the vehicle based on the maneuver parameter as transformed to the Earth frame of reference. The approach further involves providing the detected maneuver event to a signaling unit associated with the vehicle.

A control device includes a reference unit, a correction unit, and a target setting unit. The correction unit sets a reference correction current serving as a reference in determining the correction current to 0 in an extremely low velocity range of a change velocity of a stroke amount, sets the reference correction current to a predetermined steady-state value in a medium and high velocity range of the change velocity, and sets the reference correction current to a value equal to or larger than 0 and equal to or smaller than the steady-state value in a low velocity range of the change velocity.

A human-powered vehicle control device is provided for controlling a human-powered vehicle. The human-powered vehicle control device includes an electronic controller that controls a human-powered vehicle component in accordance with a control state including first and second modes. The electronic controller changes a transmission ratio of a transmission device in accordance with a first shifting condition in the first mode, and changes the transmission ratio in accordance with a second shifting condition in the second mode. The electronic controller changes the first shifting condition in accordance with a converging reference value, which is related to a traveling state of the human-powered vehicle, for a case where the human-powered vehicle is in a riding converging state in the first mode, and changes the second shifting condition in accordance with a converging reference value for a case where the human-powered vehicle is in the riding converging state in the second mode.
