Abstract: A driving assistance device comprises: an external environment detection sensor of a vehicle; and a controller configured to control a drive source of the vehicle. The controller controls the drive source so as to change acceleration of the vehicle on the basis of relative information including at least any one of an arrival time, a distance, or a relative speed with respect to a predetermined position ahead or another vehicle ahead in a self-vehicle traveling lane in which the vehicle travels, and a traveling status in another traveling lane as a merging destination on the basis of information of the external environment detection sensor.

Abstract: A driving assistance apparatus mountable on a straddle type vehicle, comprising a first detection unit configured to detect a vehicle speed of the straddle type vehicle, a second detection unit configured to detect a preceding vehicle traveling in front of the straddle type vehicle, and a control unit configured to perform acceleration control and braking control of the straddle type vehicle, wherein when the vehicle speed of the straddle type vehicle is lower than a reference, the control unit performs follow-traveling with respect to the preceding vehicle by performing the acceleration control simultaneously with the braking control.

Abstract: To provide a brake system for a saddled vehicle that exerts proper braking force control considering changes in the driver's posture during deceleration. A brake system for a saddled vehicle including a control device exerting automatic control over a brake fluid pressure of a front-wheel brake and that of a rear-wheel brake according to various information, and a throttle position detector for detecting a throttle position of a rotary-type throttle operating element mounted on a steering handlebar. When an operation on the throttle operating element is detected at start of automatic control over the front-wheel brake and the rear-wheel brake, if the throttle position is less than a predetermined threshold value, the control device maintains the automatic control, and if the throttle position is equal to or greater than the predetermined threshold value, the control device cancels the automatic control.

Abstract: To provide a brake system for a saddled vehicle that suppresses the speed at which the vehicle transitions to a front-dropping posture, thereby enhancing the driver's sense of security. A brake system for a saddled vehicle includes a control device exerting automatic control over a brake fluid pressure of a brake according to various information, and a pitch angular velocity detector for detecting a pitch angular velocity of the vehicle according to an output of a pitch angular velocity detection unit. When the pitch angular velocity becomes equal to or greater than a predetermined threshold value while the control device is gradually increasing the brake fluid pressure of the front-wheel brake by the automatic control, the control device reduces a degree of increase in the brake fluid pressure or maintains the brake fluid pressure at that time point.

Abstract: To provide a brake system for a saddled vehicle that ensures vehicle's stable behavior when a brake operating element is operated during automatic control. A brake system for a saddled vehicle includes: a control device exerting automatic control over a brake fluid pressure; and a front-wheel brake operating element and a rear-wheel brake operating element for a driver to manually operate a front-wheel brake and a rear-wheel brake.

Abstract: To provide a camera mounting structure that can protect a camera attached to the front of the body from bouncing stones or the like. In a camera mounting structure applied to a saddled vehicle with a body having a front to which a camera is attached, the camera is disposed at a position on the saddled vehicle below a headlamp and above a front fender. The camera is attached to a bracket fixed to the body. A yaw rotation shaft that allows a swinging motion in a yaw direction relative to the body is provided to the bracket. A pitch rotation shaft that allows a swinging motion in a pitch direction of the camera is provided to the bracket.

Abstract: A driving assistance apparatus according to an embodiment includes a vehicle height adjusting mechanism that adjusts vehicle height of a vehicle; a progress parameter acquiring unit that acquires a progress parameter expressing a degree of progression until the vehicle reaches a target object in front of the vehicle; and a control section that controls the vehicle height adjusting mechanism based on the progress parameter.

Abstract: An automatic control device for a motorcycle including a control device that automatically controls an automatic cruise control system and a brake system including a front wheel brake and a rear wheel brake includes a brake temperature detection unit that detects a brake temperature. The control device varies operation states of the front wheel brake and the rear wheel brake according to the brake temperature during automatic cruise control. At a time of deceleration in a case where the brake temperature during the automatic cruise control is low, the control device raises the brake temperature by reducing an engine brake of a power unit of a vehicle and increasing operation frequencies of the front wheel brake and the rear wheel brake.

Abstract: A vehicle control system includes a control part in which a public road mode that is selected at a time of traveling on a public road and a non-public road mode of a setting that is suitable for a travel in a non-public road region are set as a travel mode, wherein the control part is configured to allow a safety protection component of a vehicle to perform a normal operation that is required at a time of traveling on a public road when the public road mode is selected and is configured to allow the safety protection component to perform an alarm operation that is different from the normal operation when the non-public road mode is selected.

Abstract: A rear structure of a saddle-ride type vehicle for preventing rainwater or the like splashed by a rear wheel from entering a fresh air inlet of an engine intake system. The rear structure of a saddle-ride type vehicle includes a rear fender halved into a first fender and a second fender connected to each other. The first fender is formed with a hanging portion so as to cover the rear and upside of a rear wheel and the second fender covering the upside of the rear wheel with a fresh air inlet being provided lateral to and in front of the rear wheel. The first fender and the second fender are disposed to overlap each other in an anteroposterior direction. The second fender is disposed on the vehicle-widthwise inside of the first fender. The second fender has anteroposteriorly and downwardly extending sidewalls at both vehicle-widthwise lateral end portions.
