A control system is provided for controlling an electrical component of a human-powered vehicle in accordance with a swivel state of a riding portion and a carrier. The control system includes a sensor, an electrical component and an electronic controller. The sensor is configured to output a signal corresponding to a pivot angle of a pivot portion provided between the carrier and the riding portion located between the carrier and a handle. The electronic controller is configured to control the electrical component in accordance with the signal output from the sensor.

An accelerator position sensor according to the present invention is held inside a throttle grip of a vehicle rotationally operated by a driver. The accelerator position sensor includes: a magnet extended along a rotation axis of the throttle grip and configured to rotate in conjunction with the throttle grip; a magnetic detection unit arranged so as to face a predetermined face of the magnet; and a magnetic body arranged so as to face another face that is different from the predetermined face of the magnet. On the predetermined face and the other face of the magnet, respectively, mutually different numbers of magnetic poles are magnetized along a rotation direction of the magnet.

There is provided a straddle type vehicle including a processing circuit. The processing circuit is configured to: change, upon receiving a boost signal from a boost input device, a target torque from a normal torque to a boost torque obtained by adding a predetermined boost amount to the normal torque; and correct, upon receiving a predetermined inclination signal from the posture detector, the target torque such that a torque change of the drive wheel when the target torque is changed from the normal torque to the boost torque is decreased as compared with a case where the inclination signal is not received.

A motorcycle includes an electric motor having an output shaft defining a motor axis, a rear wheel drivably coupled to the electric motor to propel the motorcycle, a swingarm rotatably supporting the rear wheel, and a frame. The frame includes a main frame member supporting the electric motor and the swingarm. A case of the electric motor is a stressed member of the frame between the main frame member and the swingarm. The swingarm is coupled to the case of the electric motor to define a swingarm pivot axis that is co-axial with the motor axis.

A calculation method and apparatus for calculating a starting point for acceleration/deceleration operation of a vehicle with high accuracy using more input values while at the same time keeping calculation cost and time to a minimum is disclosed herein. An ECU making up a system calculates a start point for acceleration/deceleration operation of a vehicle on the basis of traveling condition information that changes as the vehicle travels and vehicle information that changes only slightly as a result of the travel of the vehicle. As a result, if the driver maintains a throttle operator at a given opening angle or more at a point before the start point, an actuator applies a force in the direction of closing a throttle valve to the throttle operator, thereby notifying the driver that the vehicle is close to the start point.

An embodiment of present application discloses a light sensing module for use with a reflector. The light sensing module includes a housing, an optical transceiver, and a shading hood. The housing includes a through hole. The optical transceiver includes a light source, a light sensor, and a separating wall. The light source is disposed in the housing for emitting a first light. The first light can pass through the housing via the through hole, and be reflected as a second light by the reflector. The light sensor is disposed in the housing for receiving the second light. The separating wall is disposed between the light source and the light sensor. The shading hood is located at a position corresponding to the light sensor, and has an opening positioned in an optical path of the second light.
