Motorcycle riders, being more vulnerable than drivers of four-wheeled vehicles, can especially benefit from advance warnings of hazards. Hazards are detected in the predicted path of the motorcycle or are predicted to be in the path within the next few seconds of the motorcycle's travel. The outputs from the sensors that detect the hazards are corrected for the lean of the motorcycle as it corners. The predicted path or ego lane of the motorcycle is also adjusted depending on the lean of the motorcycle.

A human-powered vehicle control device includes an electronic controller that is configured to control a motor that assists in propulsion of a human-powered vehicle and that stops assisting in the propulsion of the human-powered vehicle at a timing suitable for a state of the human-powered vehicle or a state of a road. The electronic controller drives the motor in correspondence with a human drive force upon determining a traveling speed of the human-powered vehicle is less than a predetermined speed that is higher than 0 km/h. The electronic controller varies the predetermined speed in correspondence with at least one of a state of the human-powered vehicle and a state of a road on which the human-powered vehicle travels. The electronic controller does not assist the propulsion of the human-powered vehicle upon determining the traveling speed of the human-powered vehicle is greater than or equal to the predetermined speed.

A bicycle includes a vehicle-body frame, a front wheel that is a steered wheel, a rear wheel, a crankshaft, a pedal, a transmission to transmit rotation of the pedal to the rear wheel, a motor to apply at least a torque to cause rearward rotation of at least one of the front wheel or the rear wheel, a roll detector to detect at least one of a roll angle or a roll angular velocity of the vehicle-body frame, and a steering detector to detect a direction of steering. When a vehicle speed is zero and a steering angle of the front wheel is not zero, the motor applies, to the at least one of the front wheel or the rear wheel, a torque to maintain the roll angle of the vehicle-body frame based on the detected direction of steering and the at least one of the roll angle or the roll angular velocity.

The posture of the driver is detected from the driver head portion, and the detected value and the driver mounting determination value are used to determine that the driver is pushing the vehicle and obtain the vehicle pushing command value. Converts the vehicle pushing command value to the target vehicle pushing assistance vesicle speed, determines whether vehicle pushing assistance can be performed based on the driver's posture and the vehicle condition, and outputs the vehicle pushing assistance permission determination. Then, from the target vehicle pushing assistance vehicle speed and the vehicle pushing assistance permission determination, the control amount for the vehicle power source that assists the vehicle pushing is calculated and output.

A device for assisting the movement of a load along a surface, the device includes a one-wheeled gyropod equipped with a motorized wheel intended to roll along the surface, with a frame, and with at least one gyroscopic sensor making it possible to measure an inclination of the frame, the gyroscopic sensor controlling the motorization of the wheel, two lateral supports connected to the frame and able to move along the surface, a mechanism for braking each of the two lateral supports, configured to brake the movement of the lateral support in question along the surface as a function of a reaction force exerted by the surface on the lateral support in question.

A vehicle illumination system provided in a vehicle capable of traveling around a corner by inclining a vehicle body toward a turning direction includes: a headlamp mounted on a front portion of the vehicle; a communication lamp disposed on the vehicle body in a region adjacent to the head lamp so as to be visible from ahead of the vehicle; and an illumination control unit configured to change a lighting mode of the communication lamp depending on a state of the vehicle.

A straddle type vehicle has a rear detection unit configured to detect an object in a detection region behind a vehicle, and a notification unit configured to notify a driver when the object is detected by the rear detection unit. The straddle type vehicle comprises: an acquisition unit configured to acquire travel information of the straddle type vehicle; an identification unit configured to identify a turning direction and a turning radius of the straddle type vehicle on the basis of the travel information; and a change unit configured to change straight-ahead-travel detection region settings for the rear detection unit on the basis of the turning direction and turning radius.

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 communication system for a vehicle comprises a mechanism for sensing a braking of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle's headlights based upon the braking of the vehicle. In particular, a headlight of the vehicle is able to be modulated based upon an application of one or both of a front brake and a rear brake. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.
