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.

The present invention obtains a controller capable of improving safety of a motorcycle. The controller that controls vehicle body behavior of the motorcycle includes: an acquisition section that acquires trigger information generated in accordance with peripheral environment of the motorcycle; and an execution section that initiates a control mode making the motorcycle execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section and makes the motorcycle generate a braking force. The acquisition section further acquires seat load information that is information of a load received by a seat of the motorcycle, and the execution section changes the automatic brake operation, which is executed in the control mode, in accordance with the seat load information acquired by the acquisition section.

A control device is provided to a human-powered vehicle. The control device includes an electronic controller. The electronic controller is configured to control an air pressure of a tire provided to the human-powered vehicle, based on at least one of a roughness of a road surface on which the human-powered vehicle is traveling or will travel, a slope state related to an advancing direction of the human-powered vehicle, a wet state of a road surface, a traveling state of the human-powered vehicle, and a state of a component mounted on the human-powered vehicle.

A lighting system for a vehicle having a housing, a plurality of elements generating an intensity of light and a controller. The controller selectively changing the intensity of at least one of the plurality of elements based on a sensed condition.

A fuel filling device of a motorcycle can receive a high pressure gas only when it is ensured that the motorcycle is in a stable position. The device includes a fuel tank that stores and/or supplies a high pressure gas and is mounted on the motorcycle, a filling port through which the high pressure gas is fed to the fuel tank, a center stand that swings between a raised position in which the center stand supports the motorcycle in an upright position and a retracted position, a stand sensor that senses that the center stand is in the raised position, and a fuel filling valve provided between the fuel tank and the filling port and allowing a flow of the high pressure gas between the fuel tank and the filling port if the stand sensor senses that the center stand is in the raised position.

A leaning suspension system for vehicles includes suspension arms that rotate about the same pivoting point. A swing frame also rotates about the same pivoting point. The center of gravity of the vehicle remains lower than the pivoting point even when the vehicle is leaning. A wheel mount assembly is rotatably mounted to a suspension arm. A shock absorber has an end that is connected to the wheel mount assembly and another end that is connected to the suspension arm. A control unit of the vehicle includes a computer that controls actuators of the leaning suspension system based on received sensor information. The vehicle can be a tricycle or a quadracycle.

A method is described for determining a position of a two-wheeled vehicle. The single-track vehicle has a vehicle path yaw rate when driving along curves and a yaw rate according to the inclined orientation which differs from the vehicle path yaw rate. An inclined orientation of the single-track vehicle and a speed of the single-track vehicle are measured. The vehicle path yaw rate of the single-track vehicle is determined from the measured inclined orientation and the measured speed. A device for carrying out the method is also described.

The present invention relates to a safety system device for the benefit of cyclists, and in general of all drivers of two and three-wheeled and it can also be used by runners, when they circulate in the streets.

The invention comprises a light indicator that is suitable to signal, when a cyclist makes a change of direction, and the rider tries to signal this maneuver by moving outwards the arm corresponding to the side towards which the direction of travel is changing.

This device integrates: a lighting element designed to switch on and off according to an appropriate electrical command, an electrical power supply unit, a triaxial accelerometer and an inclinometer sensor. It also comprises calculation means for processing the signals supplied by the triaxial accelerometer and the inclinometer sensor, carrying out an interpretation of the meaning of the movement of the arm.

A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

A calculation method and apparatus for calculating a starting point for acceleration/deceleration operation of a vehicle with high accuracy using more input values while at the same time keeping calculation cost and time to a minimum is disclosed herein. An ECU making up a system calculates a start point for acceleration/deceleration operation of a vehicle on the basis of traveling condition information that changes as the vehicle travels and vehicle information that changes only slightly as a result of the travel of the vehicle. As a result, if the driver maintains a throttle operator at a given opening angle or more at a point before the start point, an actuator applies a force in the direction of closing a throttle valve to the throttle operator, thereby notifying the driver that the vehicle is close to the start point.
