A method for laterally stabilizing a single-tracked motor vehicle, driven with the aid of an electric motor, that is in a vertically aligned state and at a standstill. The front wheel of the motor vehicle has a steering angle in which the electric motor is controlled in such a way that it exerts drive torques on the motor vehicle that act in alternation in the forward direction and in the reverse direction.

The present invention relates to electric bicycle speed control device and method. According to the present invention, a torque of a motor for driving a wheel is controlled so that a speed of a pedal driven by a user follows a speed of the wheel, and a torque of the pedal is also controlled by applying an assist level according to the torque of the motor. Therefore, even in an electric bicycle with a chain, it is possible to feel a feeling of the pedal like a bicycle with a chain, and it is possible to adjust the force applied to the pedal according to the assist level.

A travel control device for controlling traveling of a straddle-type vehicle includes a control device, a vehicle speed detector configured to detect a traveling speed of the vehicle, and a vibration detector configured to detect a detection target vibration which is a vibration in a yaw direction or roll direction of the vehicle and has a frequency within a reference frequency range. The control device includes a deceleration device configured to perform a deceleration control to decelerate the traveling speed if the traveling speed exceeds a control start reference speed and an amplitude of the detection target vibration exceeds a control start reference amplitude and a deceleration stop device configured to stop the deceleration control if the traveling speed becomes equal to or less than a target limited speed after the deceleration control is started by the deceleration device.

The present disclosure relates to a suspension system (200) that is installed on a vehicle and is capable of performing functions including park locking, returning momentum, tilt limiting and rear suspension. The suspension system (200) comprises a rear suspension mounting structure (302), a rear suspension swing arm (306), a tilt limiting structure (201), and a tilt restoring structure (202). The rear suspension swing arm (306) is pivotally coupled to the rear suspension mounting structure (302) and configured to rotate about the rear suspension mounting structure (302) in response to a tilting movement of the vehicle. The tilt limiting structure (201) is configured to mechanically inhibit the tilting movement when a tilt angle of the vehicle exceeds an instantly-calculated tilt angle value. The tilt restoring structure (202) is configured to apply a force in response to the tilting movement.

A vehicle lamp tool providing a controller which calculates the luminance distribution of light distribution pattern, an optical device which generates light distribution pattern in an illuminatable area D and a first driving circuit which drives the optical device. The controller transmits a first light distribution correction signal for correcting the inclination of a current light distribution pattern to the first driving circuit if the inclination angle of a vehicle with respect to vertical direction indicated by a detection signal received from a vehicle height sensor is equal to or less than a threshold value. The first driving circuit transmits a first correction driving signal based on the first light distribution correction signal to the optical device. The optical device drives an LD and a light deflector to correct the current light distribution pattern.

A lighting system and method of operating the same for a vehicle having a vehicle structure includes a plurality of primary low beam elements and a plurality of secondary low beam elements. The system further includes a primary high beam element and a secondary high beam element. A lean angle sensor is coupled to the vehicle structure. A controller is coupled to the lean angle sensor controlling the primary low beam elements, the secondary low beam element and the secondary high beam element in response to the lean angle.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.

A falling-over detection device is mounted on a motorcycle. The falling-over detection device includes an acceleration sensor that detects acceleration at an interval decided by an interval adjusting device, a threshold value determining device that determines whether or not a detected angle is larger than a predetermined threshold value, a counting device that counts the number of times it is determined that the detected angle is larger than the threshold value, and a falling-over determining device that determines that the motorcycle has fallen over in a case where the count is successive a predetermined number of times. The interval adjusting device uses a pulse generated based on white noise as an interval, and therefore noise does not successively affect a value detected by the acceleration sensor.

Fixed-beam headlights reduce a rider's intended visual field by pointing away from a corner during turning. A system is presented for improving visibility in dark conditions on a motorcycle. It relates to adaptively controlling headlight orientation. Based on sensor data, the headlight beam is rotated independently in three degrees of freedom, in real time. This maintains illumination of the road ahead, even when cornering, and reduces the blinding of oncoming traffic. High beam and low beam operation is accommodated, including dimmable high beams. The beam is directed with three independent motors in one embodiment, by the switching of light-emitting diodes in an array in another embodiment, or using a hybrid motorized and solid-state system. The adaptive headlights are suitable for craft other than motorcycles.
