Abstract: In an electric vehicle, a torque to rotate a drive wheel is generated by a motor. An accelerator grip is operated by a rider in order to adjust the torque of the motor. An operation amount of the accelerator grip is detected by an accelerator sensor. Further, a brake lever is operated by the rider in order to brake a main body. A controller is programmed to control the motor such that the torque of the motor gradually decreases when the brake lever is switched from a non-operation state to an operation state with the torque being generated by the motor.

Abstract: A motorcycle sets a target slip value based on an accelerator operation by a driver, and prevents a significant decrease in the output torque of the drive power source during execution of traction control to provide a comfortable ride. The motorcycle includes a target slip value calculating section that calculates a target slip value, based on an accelerator operation by a driver; and an actual slip value calculating section that calculates an actual slip value, based on the difference between the rotation speed of the front wheel and the rotation speed of the rear wheel. The motorcycle further includes a drive power source controller arranged and programmed to reduce the output torque of the drive power source, based on the difference between a criterion value different from the target slip value and the actual slip value when the actual slip value is lower than the target slip value.

Abstract: Traction control for a motorcycle including a driving wheel speed sensor and a driven wheel speed sensor. An ECU controls an engine on the basis of a corrected slip signal obtained by subtracting a low frequency component of a pre-correction slip signal from the pre-correction slip signal. The pre-correction slip signal is obtained by subtracting a speed of a front wheel detected by the driven wheel speed sensor from a speed of a rear wheel detected by the driving wheel speed sensor.

Abstract: A laser scanning optical system converts a plurality of beams emitted from the laser diode (LD) into parallel light using a collimator lens, shapes the parallel light using an aperture, and executes exposure of a plurality of lines simultaneously on a photoreceptor drum. To cause a necessary emitting point interval d determined uniquely from the magnification of the optical system to coincide with an emitting point interval of the LD used, the LD is rotated by an angle ? against the main optical axis plane thereof. In this case, a converting device that converts the aspect ratio of a profile of the light beam emitted from the LD is provided. A conversion characteristic of the converting device is adjusted such that the characteristic is matched with a condition within a predetermined region following a characteristic of the optical system.

Abstract: A control device for a straddle-type vehicle includes a first storage means configured to store a target cruise control speed, and a first detection program which senses if the vehicle accelerator is operated in the further closing direction from the totally closed position of the accelerator. The control device also includes a deceleration processing program which decreases the stored target cruise control speed when the first detection program detects the further closing operation during cruise control. The deceleration processing program varies the rate at which the stored target cruise control speed is decreased according to the magnitude of the operating force utilized in the further closing operation.

Abstract: A straddle type vehicle includes a protrusion which is displaced together with a throttle valve, a lever pulley which is displaced in response to the rotation of a throttle grip, a spring and a control device. The spring generates elastic force to return the protrusion to a first original position when the lever pulley is in a second original position. The spring maintains the lever pulley in the second original position by being elastically deformed until the protrusion reaches a predetermined position in which the protrusion is displaced from the first original position in such a direction that the throttle valve opens when the lever pulley is in the second original position. The control device opens the throttle valve by displacing the protrusion until the protrusion reaches the predetermined position in a gear shift change when the throttle grip is fully closed.
