A method for controlling movement for a single-track motor vehicle. The distance from or the speed relative to a vehicle following behind the motor vehicle is sensed by a rear driving-environment sensor system sensing the rearward area behind the motor vehicle. In response to a drop below a distance limiting value or if a relative-speed limiting value is exceeded, warning information is output for the driver of the single-track motor vehicle.

A method includes ascertaining that an emergency braking operation of a single-track motor vehicle is to be automatically executed driver independently, and based on the ascertainment, automatically and driver-independently influencing a steering element of the motor vehicle during the execution of the emergency braking operation.

A method of conducting a diagnostic procedure for a braking system includes analyzing via an electronic control unit whether only a first input device is engaged or only a second input device is engaged, conducting a first diagnostic test if only the first input device is engaged, and conducting a second diagnostic test if only the second input device is engaged.

An embodiment of this invention relates to a motor driving control apparatus for a moto-assisted vehicle, which includes a driving unit configured to drive a motor, and a controller configured to determine a regeneration amount based on a first speed of a vehicle that moves by the motor driven by the driving unit, and control the driving unit according to the regeneration amount, wherein the first speed is a speed at a first timing when it is detected that a brake of the vehicle is changed to OFF, or is determined based on temporal change in an acceleration of the vehicle.

The invention obtains a controller and a control method capable of improving safety by an automatic braking operation while preventing a motorcycle from falling over. The invention also obtains a brake system that includes such a controller.

In the controller and the control method according to the invention, a control mode that makes the motorcycle execute the automatic braking operation is initiated in response to trigger information generated in accordance with peripheral environment of the motorcycle. In the control mode, distribution of an automatic braking force to a front wheel and a rear wheel is controlled in accordance with travel posture of the motorcycle, and the automatic braking force is a braking force that is applied to the wheels of the motorcycle by the automatic braking operation.

A saddle-type vehicle having at least one seat and at least two wheels, at least one electric motor, a motor controller, a rechargeable energy storage system (RESS) such as a battery and battery management system, at least one friction foundation or ABS braking system as a first braking system and at least one electric regenerative braking system as a second system where the two braking systems are linked to allow for simultaneously providing conventional and regenerative braking independently to the front and rear wheels of the vehicle.

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.

Provided are a vehicle body behavior control device which can reduce unstable behavior of a vehicle body and a method of controlling behavior of a vehicle body which can reduce unstable behavior of the vehicle body. A vehicle body behavior control device incorporated into a vehicle body having a plurality of wheels includes: a behavior control mechanism which controls behavior of the vehicle body; and a control part which controls an operation of the behavior control mechanism based on an axle load applied to the wheel calculated using a gradient value of a road surface.

A wheelie determining device comprises a lift-off start determiner section which determines whether or not a lift-off of a front wheel from a ground surface has started, based on a traveling state value indicating a traveling state of a vehicle and an operation value indicating a rider's driving operation.

An emergency braking system of a single-track vehicle configured to intervene in a braking process of the single-track vehicle is provided. The emergency braking system includes a plurality of sensors that determine various physical variables. From the physical variables an accident risk actual value is determined, compared with an accident risk target value using an emergency braking system control unit, and if the accident risk actual value exceeds the accident risk target value, the single-track vehicle's brake is actuated by the emergency braking system control unit.
