Provided is a saddled vehicle capable of optimizing distribution of a braking force between front and rear wheels at the time of deceleration during linear traveling, before entering a corner, and in a similar situation. A saddled vehicle () includes: a front wheel braking component () that applies a braking force to a front wheel (WF); and a rear wheel braking component () that applies a braking force to a rear wheel (WR), and is configured to operate the front wheel braking component () and the rear wheel braking component () in an interlocking manner in response to an operation of an operating element () as a single operating element. In response to the operation of the operating element (), the front wheel braking component () first starts operating, and thereafter, in response to a braking condition of the front wheel braking component () satisfying a first condition, the rear wheel braking component () starts operating. In response to satisfaction of the first condition, the braking force of the rear wheel braking component () is increased while the braking force of the front wheel braking component () is maintained at a first front-wheel-braking force (P1).

Saddled vehicle

The present invention provides a control device that controls a suspension mechanism of a straddle type vehicle, comprising: a wheel speed sensor configured to detect a wheel speed of the straddle type vehicle; an estimation unit configured to estimate a stroke speed of the suspension mechanism, based on a change in the wheel speed detected by the wheel speed sensor; and a correction unit configured to correct the stroke speed estimated by the estimation unit, in accordance with a circumferential length of a grounding part of a tire changed by turning of the straddle type vehicle.

Control device, vehicle, estimation method, and storage medium

The present invention provides a control device of a vehicle, comprising: a detector configured to detect acceleration in a front-and-rear direction generated in the vehicle; and an estimation unit configured to calculate a braking force of the entire vehicle and a pitch angle of the vehicle based on the acceleration detected by the detector, and estimate an amount of nose dive of the vehicle during braking of the vehicle based on the calculated braking force of the entire vehicle and the calculated pitch angle of the vehicle.

An estimation device estimates a stroke quantity indicating a displacement in an up-and-down direction of a vehicle, in a multistage elastic member in which a plurality of members, each having a different load displacement characteristic indicating a relationship between a load and the displacement, are disposed. The estimation device comprises: a load calculation unit configured to calculate a variable ground contact load received by a wheel of the vehicle from a ground contact surface; a state quantity estimation unit configured to estimate the stroke quantity generated in the multistage elastic member; and a characteristic change unit configured to change a setting of the initial value to an estimated load displacement characteristic.

The rocking control device for a two front wheels rocking vehicle includes a controller that executes a first rocking control which assists a rocking of the two front wheels rocking vehicle and a second rocking control which assists the two front wheels rocking vehicle so that the two front wheels rocking vehicle self-stands at a rocking balanced position where a rocking moment of the vehicle body is canceled out in a lateral direction, wherein controller is configured to switch the first rocking control and the second rocking control to OFF state, and is configured to operate the first rocking control and the second rocking control in combination.

Rocking control device for two front wheels rocking vehicle

A rocking control device for a two front wheels rocking vehicle includes a high rigidity self-standing controller that executes a high rigidity self-standing control that locks the rocking of the two front wheels rocking vehicle and that assists a self-standing of the two front wheels rocking vehicle, a switch that switches the high rigidity self-standing control to ON or OFF state, and an offset cancellation controller that executes an offset cancellation control that maintains the self-standing state of the two front wheels rocking vehicle until a predetermined traveling state when the high rigidity self-standing control is switched off.

A remaining fuel amount warning device for a vehicle, the remaining fuel amount warning device giving a warning that an amount of fuel remaining in a fuel tank is smaller than a predetermined value on the basis of output of a fuel gauge measuring the remaining fuel amount, includes combustion state changing device for changing the combustion state of an engine. When the remaining fuel amount becomes smaller than the predetermined value, the remaining fuel amount warning device performs remaining amount warning control that produces vibration different than during normal operation by changing the combustion state of the engine by the combustion state changing device. A starter switch for starting the engine is made to serve also as a warning acknowledging button for stopping the remaining amount warning control for a predetermined time on the basis of an operation by an occupant.

An axle extends in an axial direction. A front wheel is rotatable around a wheel rotational axis. A front wheel supporting arm rotatably supports the axle. A front fork swingably supports the front wheel supporting arm such that the front wheel supporting arm is rotatable in a first direction about the wheel rotational axis. A rotary member is rotatable together with the axle around the wheel rotational axis. An axle rotation detector is supported on the axle opposite to the rotary member in the axial direction to be rotatable around the wheel rotational axis to detect a difference between rotational speeds of the axle rotation detector and the rotary member. A link mechanism is provided between the axle rotation detector and the front fork to turn the axle rotation detector in a second rotational direction opposite to the first rotational direction about the wheel rotational axis.
