A method and an apparatus for monitoring a motorcycle. Based on the acceleration-relevant data, a vehicle motion and a vehicle position in three-dimensional space are estimated. The vehicle position in space is analyzed and is evaluated as a normal or a critical riding state. A detection direction of a sensor unit is predefined in such a way that in an upright normal resting position of the motorcycle the detection direction lies in a horizontal plane, and the detected acceleration-relevant data encompass a first acceleration component in a longitudinal vehicle direction and a second acceleration component in a transverse vehicle direction. A riding state evaluated as critical is plausibilized with the estimated vehicle motion in order to recognize a critical resting position after an accident. An emergency call is generated when a critical resting position after an accident is recognized.

A control apparatus of a straddle vehicle includes: a prediction section that determines whether a rider of the straddle vehicle intends to turn the straddle vehicle and predicts whether turning of the straddle vehicle will occur, based on information related to at least one of a predetermined behavior exhibited by a vehicle body of the straddle vehicle before turning and a predetermined driving operation performed by the rider; and a vehicle control section that provides driving assistance during turning of the straddle vehicle based on a result of the prediction made by the prediction section.

Described herein is a stabilizer system to a rider having limited leg mobility to operate a motorized vehicle having one or more wheels. Multiple embodiments are described, with differing embodiments configured for different mounting positions on different types, makes, and models of motorcycle. One embodiment can mount to a rear frame mount of a sport style motorcycle, while another embodiment can be configured to mount to a lower frame mount of various styles and types of motorcycles. Each embodiment can be controlled via a handlebar mounted switch device, which can be used to raise or lower a stabilization system via an electrically and/or hydraulically powered actuator.

A bicycle seatpost system is basically provided with a height adjustable seatpost and an electronic controller. The height adjustable seatpost includes an electric actuator. The electronic controller is configured to control the electric actuator to change a height of the height adjustable seatpost in accordance with detected information about a change of orientation of a bicycle relative to a ground.

A lighting system for a vehicle having a vehicle structure has a housing and a lens. A plurality of light sources are disposed within the housing. A sensor is disposed between the housing and the lens and senses a condition outside the lens.

A method is described for operating a two-wheeled vehicle, in particular a motorcycle, on a roadway, the method including the following steps: ascertaining an instantaneous coefficient of friction between at least one wheel of the two-wheeled vehicle and the roadway; calculating a critical tilt angle of the two-wheeled vehicle as a function of at least the instantaneous coefficient of friction; detecting an instantaneous tilt angle of the two-wheeled vehicle; determining the distance between the instantaneous tilt angle and the critical tilt angle; and outputting an item of information to the driver as a function of the determined distance.

The present invention provides a saddle ride type vehicle including a sensing unit configured to sense a four-wheel vehicle that is present in front of a self-vehicle and is traveling in a travel lane of the self-vehicle, and a control unit configured to, in a case where the four-wheel vehicle is sensed by the sensing unit, perform follow-travel control for causing traveling of the self-vehicle to follow traveling of the four-wheel vehicle, wherein the sensing unit senses a vehicle width of the four-wheel vehicle, and the control unit, in the follow-travel control, controls a travel position in a vehicle width direction of the self-vehicle so that at least a portion of the self-vehicle falls within a region within the vehicle width of the four-wheel vehicle.

A vehicle includes an in-vehicle device and a speaker array. The in-vehicle device is capable of changing a sound outputted from the speaker array to a sound arriving from a virtual sound source that is set to a predetermined position by use of a sound control portion. The speaker array is configured to be changeable in posture relative to the vehicle and to adjust a position of a virtual sound source relative to the vehicle.

Disclosed is a vehicle. The vehicle generally includes a frame to support an engine and one or more supports, such as wheels, to support the frame. The engine may include an internal combustion power plant and a fuel supply system therefore.

A human-powered vehicle control device includes an electronic controller that controls a human-powered vehicle component including at least one of a motor assisting in propulsion of a human-powered vehicle and a transmission changing a first ratio of a rotational speed of a drive wheel to a rotational speed of a crank of the human-powered vehicle. The electronic controller controls the human-powered vehicle component in a first control state and a second control state differing from the first control state. The electronic controller changes the first control state to the second control state upon determining a value related to a first change rate of an inclination angle of the human-powered vehicle is greater than or equal to a first predetermined value in the first control state. The inclination angle of the human-powered vehicle includes at least one of a yaw angle and a roll angle of the human-powered vehicle.
