A self-balancing bicycle system is provided by the present disclosure. The system includes a bicycle, a sensor coupled to the bicycle, a steering control assembly comprising an actuator and being coupled to the bicycle and configured to adjust a steering angle of a front tire of the bicycle, and a controller coupled to the sensor and configured to receive a value from the sensor. The controller is further coupled to the steering control assembly and further configured to adjust the steering angle based on the value.

A vehicle includes a vehicle frame, a steering swivel unit supported on a head pipe of the vehicle frame and angularly movable about a steering axis, a steering handle mounted on the steering swivel unit, and a cover assembly covering the steering swivel unit from above, wherein the cover assembly includes a fixed cover fixed to a vehicle body and a movable cover covering an upper opening defined in the fixed cover, and the movable cover is angularly movable in unison with the steering handle.

Provided is a vehicle control device capable of improving robustness against an attitude change of an occupant during preceding vehicle follow-up control in a straddle type vehicle such as a motorcycle. A vehicle control device 100 for a straddle type vehicle that controls a driving force during preceding vehicle follow-up control for causing an own vehicle to follow a preceding vehicle, in which the driving force (which is a control amount of the preceding vehicle follow-up control) is corrected according to an attitude (attitude change) of a driver detected by an attitude detection device 800 during the preceding vehicle follow-up control. Further, the driving force is corrected on the basis of the attitude, the driving torque of the own vehicle, and the acceleration of the own vehicle. In addition, the driving force (according to the attitude) is corrected from at least one of the own vehicle speed of the own vehicle, the target speed, the inter-vehicle distance between the own vehicle and the preceding vehicle, the target inter-vehicle distance, and the relative speed.

The invention obtains a straddle-type vehicle information processor and a straddle-type vehicle information processing method capable of recognizing that a traveling straddle-type vehicle enters a falling phase with a high degree of accuracy at appropriate timing and thereby contributes to improvement in occupant safety.

A straddle-type vehicle information processor 10 includes: a posture information acquisition section 11 that at least acquires a roll rate Rr and a yaw rate Ry generated in a traveling straddle-type vehicle 1 as posture information; and a falling phase recognition section 12 that recognizes that the straddle-type vehicle 1 enters a falling phase in the case where a change in a degree of instability over time, which is derived at least on the basis of the roll rate Rr and the yaw rate Ry, shows an increasing tendency.

The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

The present disclosure belongs to the technical field of two-wheel vehicles. A two-wheel automatic balance reset mechanism comprises a balance bar arranged between a frame and each front wheel support, the balance bar comprises a piston cylinder and a piston rod, the piston rod is movably arranged in a piston chamber of the piston cylinder, two ends of the piston chamber are mutually interconnected to form a first channel, a main control valve is arranged on the first channel and divides the first channel into a medium intake end and a backflow end, a medium tank is arranged at the backflow end, a pump is arranged at the medium intake end, and the pump is interconnected with the medium tank. A system comprises a main control module and an acquisition module, and the acquisition module comprises a balance sensor arranged on the frame and a speed sensor.

A transmission control system is configured to be used with a human-powered vehicle that includes a crank, a first rotation body rotated independently from the crank, a drive wheel, a second rotation body rotated independently from the drive wheel, a transfer body that transfers rotation force between the first and second rotation bodies, and a transmission that controls the transfer body and shifts a transmission ratio. The transmission control system includes a motor that drives the transfer body, a first detector that detects at least one of acceleration and vibration of the human-powered vehicle, and an electronic controller configured to control the motor in accordance with a detection result of the first detector upon generation of a shift request for the transmission in a state in which the drive wheel is rotated and a rotational angle of the crank is maintained in a predetermined range.

This vehicle-mounted device is a vehicle-mounted device mounted on a vehicle that has a body and a steering unit supported on the body via a steering shaft, and includes a user interface, camera, or antenna attached to the steering unit; a first sensor unit that is attached to the body and detects a first angular velocity or a first acceleration as a first detection value; and a calculation device that performs calculation based on the first detection value and is connected to the user interface, camera, or antenna.

This measurement device for measuring the angular velocity or acceleration of a two-wheel vehicle, is provided with a main detection unit which detects the three-axis angular velocity or three-axis acceleration, a support unit which can support the main detection unit on the body of the two-wheel vehicle, and a correction unit which cancels the lean of the body to the left and right in the main detection unit.

A motorcycle includes a pair of left and right front forks, a headlight, cover members (side cowls and light covers), and camera units. A front wheel is rotatably attached to the pair of left and right front forks. The headlight irradiates a forward side. The cover members each having an internal space are disposed at least laterally outside the pair of left and right front forks in a front view. The camera units detect the forward side by acquiring visible light which is one kind of electromagnetic waves (by acquiring images). In a front view, the camera units are disposed below the headlight and laterally outside the pair of left and right front forks. The camera units are disposed in the internal spaces of the cover members.
