The present invention obtains a rider-assistance system capable of appropriately assisting with driving by a rider of a straddle-type vehicle and a control method for such a rider-assistance system.

The rider-assistance system that assists with driving by the rider of the straddle-type vehicle includes: a peripheral environment detector that is mounted to the straddle-type vehicle and detects peripheral environment of the straddle-type vehicle; an input device that is mounted to the straddle-type vehicle and is operated by the rider of the straddle-type vehicle; and a controller that governs operation of the rider-assistance system. The controller includes: an acquisition section that acquires pitch angle correction target information that is target information on pitch angle correction of the peripheral environment detector; and a correction operation performing section that performs correction operation for detection of the peripheral environment by the peripheral environment detector on the basis of the pitch angle correction target information acquired by the acquisition section.

A power unit includes at least one drive source that outputs rotational power to a drive target other than pumps; a first pump rotationally driven by the rotational power of the drive source; a second pump rotationally driven by the rotational power of the drive source, the second pump being different form the first pump; and a power transmission structure that transmits the rotational power of the drive source to the first and second pumps. The power transmission structure includes transmission components and transmits the rotational power to the first pump through one of the transmission components and to the second pump through another of the transmission components.

An information providing device 1 of a motorcycle includes: an image acquisition section 10 that acquires an image of a road; a lane detection section 12 that detects a lane from the image and detects a radius of curvature of the detected lane and a lateral distance from the host vehicle to the lane; a host vehicle trajectory curvature calculation section 14 that calculates a radius of curvature of a host vehicle trajectory on the basis of the radius of curvature of the lane and the lateral distance; a vehicle speed acquisition section 16 that acquires a vehicle speed of the host vehicle; an inclination angle calculation section 18 that calculates an inclination angle of the host vehicle on the basis of the radius of curvature of the host vehicle trajectory and the vehicle speed.

Disclosed is a vehicle. The vehicle generally includes a frame to support an engine and one or more supports, such as wheels, to support the frame. The engine may include an internal combustion power plant and a fuel supply system therefore.

A drive assistance device (24) for a saddle type vehicle (1) includes a ride sensor (37) configured to detect a ride attitude of a rider (J), a vehicle body behavior generating part (25) configured to generate a behavior on a vehicle body by a prescribed output, and a controller (27) configured to control driving of a plurality of devices (BR, EN, ST) included in the vehicle body behavior generating part (25), and, when at least one of the plurality of devices (BR, EN, ST) is actuated regardless of the operation of the rider (J), the controller (27) determines which of the plurality of devices (BR, EN, ST) is to be actuated according to the ride attitude of the rider (J) detected by the ride sensor (37).

A vehicle with a power unit includes: a body frame with said power unit mounted to said body frame; at least one front wheel supported by the body frame in a front portion, and at least one rear wheel supported by the body frame in a rear portion; an electric machine capable of assisting said power unit; and an auxiliary power source electrically connected to said electric machine. The vehicle further includes a first set of foot pegs for a rider and a second set of foot pegs for a pillion. A quadrilateral region is defined between said first set of foot pegs and said second set of foot pegs, and said electric machine and said auxiliary power source are disposed substantially within said quadrilateral region when viewed from vehicle top.

An operating device for a vehicle has a handle and an actuator device that comprises a magnetorheological medium, which is coupled to the handle and is designed to exert a setting force on the handle that is dependent on a viscosity of the magnetorheological medium.

This driving support device of a saddle-riding type vehicle includes: an external detection means (29) that detects a situation around the vehicle; a steering device (ST) that steers an own vehicle; and a control means (27) that controls drive of the steering device (ST), wherein the control means (27) operates the steering device (ST) according to the situation around the vehicle detected by the external detection means (29) regardless of an operation of a rider (J) and moves a traveling trajectory in a lane width direction within a lane in which the own vehicle is traveling.

A drive assistance device (24) for a saddle type vehicle (1) includes a ride sensor (37) configured to detect a ride attitude of a rider (J), a vehicle body behavior generating part (25) configured to generate a behavior on a vehicle body by a prescribed output, and a controller (27) configured to control driving of the vehicle body behavior generating part (25), the vehicle body behavior generating part (25) includes a brake device (BR) configured to brake a host vehicle, and wherein, when the brake device (BR) is actuated regardless of an operation of the rider (J), the controller (27) actuates the brake device (BR) according to the ride attitude of the rider (J) detected by the ride sensor (37).

Provided are a driver posture measurement device and a vehicle control device that can accurately measure the posture of a driver with a simple configuration without attaching a plurality of wireless communication units to a vehicle. The driver posture measurement device and the vehicle control device are configured such that, between one wireless communication unit provided on the vehicle side and one wireless communication unit provided on the driver side, radio waves are radiated from the wireless communication unit provided on the vehicle side, and on the basis of a radio wave arrival angle of the radio waves arriving at the wireless communication unit provided on the driver side, the driver posture is measured.
