The objective is to improve driving feeling at a time of acceleration operation or deceleration operation, by recognizing driver's intention of acceleration or deceleration during straight-ahead running. A driving-assistance control apparatus according to the present disclosure includes a straight-running determination unit that determines whether or not a vehicle is running straight, a head-position detection unit that detects a head position of a driver, a driving-posture determination unit that determines the posture of the driver, based on the head position detected by the head-position detection unit, and a driving-assistance control unit that performs acceleration preparation control for raising a reaction speed for acceleration operation or deceleration preparation control for raising a reaction speed for deceleration operation in accordance with an output of the driving-posture determination unit, when the straight-running determination unit determines that a vehicle is running straight.

The invention is a method of characterizing a road for at least one route travelled by at least one road user, with sensors: a three-axis accelerometer (ACC) and a geolocation sensor (GPS). The method comprises a measurement step (MES), a measurement processing step for disregarding (AFF) the effects related to the road user's speed in order to determine vibrations due to the road roughness, and an analysis of the vibrations to characterize (CAR) the condition of the road.

The present invention provides a control system and a control method capable of appropriately supporting driving of a motorcycle by a rider. The control system includes a tracking target vehicle identifying unit that identifies a tracking target vehicle of adaptive cruise operation, a vehicle position information acquiring unit that acquires information on the relative position of the tracking target vehicle with respect to the motorcycle during traveling, a control amount setting unit that sets a control amount in the adaptive cruise operation, and an execution unit that causes the motorcycle to execute the adaptive cruise operation, and further includes a lane position information acquiring unit that acquires information on the relative position of a lane boundary with respect to the motorcycle during traveling, in which the tracking target vehicle identifying unit identifies the tracking target vehicle, based on the position information acquired by the lane position information acquiring unit.

Haptic devices are installed in a motorcycle's handlebars, footpegs and seat to provide the rider with alerts that relate to hazards. The alert is provided before the rider notices the hazard, or before the rider reacts to the hazard. By giving advance warning, a rider is given extra time to avert a potential accident. The alerts also provide a direct instruction to the rider as to what to do to avoid the accident.

A saddle-ride vehicle includes a forward travel sensor a brake that decelerates the vehicle by actuation of a rider-operable brake control. A controller identifies a trigger for an autonomous braking event for the brake. A rider sensor system is in electrical communication with the controller and includes one or both of: a rider cognition sensor operable to detect parameters of rider cognition and report rider cognition status to the controller, and a rider physical sensor operable to detect parameters of a physical engagement between a rider and the vehicle and report rider physical engagement status to the controller. The controller is programmed to perform one or both of the following in response to the identification of the autonomous braking event trigger: checking for a positive cognitive engagement of the rider with the rider cognition sensor, and checking for a positive physical engagement of the rider with the rider physical sensor.

A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

A controller and a control method are capable of improving safety by automatic emergency deceleration action while suppressing a motorcycle from falling over. One arrangement also obtains a brake system that includes such a controller. In the controller, the control method, and the brake system, a control mode that causes the motorcycle to take the automatic emergency deceleration action is initiated in response to trigger information generated in accordance with peripheral environment of the motorcycle. In the control mode, automatic emergency deceleration that is deceleration of the motorcycle generated by the automatic emergency deceleration action is controlled in accordance with a lean angle of the motorcycle.

An information transmission device applied to an open moving machine driven by a driver who is exposed to an outside of the moving machine includes: a vibrator configured to vibrate a component of the moving machine, the driver in a driving posture being in contact with the component; and a controller communicably connected to an information providing device and configured to control the vibrator and a voice output device configured to output voice to the driver, the information providing device being configured to provide utterance information to the driver as information to be transmitted to the driver. The controller makes the vibrator operate when making the voice output device output the utterance information to the driver by the voice.

Disclosed are an audio information transmission system, method, and apparatus, and a corresponding two-wheeled vehicle and helmet. The system includes a media control apparatus and an audio switching apparatus connected to the media control apparatus. The audio switching apparatus is connected to a mobile terminal and the helmet and is configured to receive first audio information transmitted by the mobile terminal and transmit same to the media control apparatus. The media control apparatus is configured to receive and mix second audio information generated by the two-wheeled vehicle with the first audio information, to generate mixed audio information. The audio switching apparatus transmits the mixed audio information to the helmet. In the present application, the audio information transmitted by the mobile terminal and information such as navigation voices, alarms emitted by the two-wheeled vehicle are mixed. The mixed audio information is transmitted to the helmet, so that the user can obtain both the audio information transmitted by the user terminal and the navigation voices transmitted by the electric vehicle, without switching between the audio information from the mobile terminal and the navigation voices emitted by the electric vehicle. The user's driving safety is improved and the user experience is enhanced.

The present invention obtains a controller and a control method capable of improving a rider's perceptibility of a warning.

A controller (51) for a rider-assistance system (50) mounted to a straddle-type vehicle (100) includes: a determination section that determines necessity of the warning given to the rider; a haptic motion performing section that performs haptic motion at least once to reduce or increase acceleration/deceleration of the straddle-type vehicle (100) only for a moment; and an acquisition section that acquires travel state information of the straddle-type vehicle (100). The haptic motion performing section changes a priority of each wheel (3, 4) at the time of changing a braking force to reduce or increase the acceleration/deceleration only for the moment in the haptic motion according to the travel state information acquired by the acquisition section.
