When an external detection device detects an obstacle (another vehicle (T)) on either a left or right side of the own vehicle (M), a control device of a steering assistance device for a saddle type vehicle controls an assist torque so that a handle operation to the side opposite to the side on which the obstacle is detected becomes heavier (more difficult to turn) than a case in which the obstacle is not detected. The handle operation to the side on which the obstacle is detected makes a handle relatively light (makes it easier to turn) while steering assist is maintained.

Steering assistance device for saddle type vehicle

This saddle-type vehicle includes a warning vibration generator () that generates a predetermined vibration to issue a warning to a driver, the warning vibration generator () includes a warning selection unit () that selects a predetermined warning in accordance with a strength of driving assist control, and, in accordance with the warning selected by the warning selection unit (), the warning vibration generator () generates a vibration (a haptic vibration) as a warning in a frequency band that avoids a vibration frequency common to a motorcycle.

Saddle-type 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.

A straddle type vehicle comprises a steering mechanism configured to steer a front wheel a steering damper device capable of variably generating a damping force working on a rotating action of the steering mechanism; and a control unit configured to control the damping force of the steering damper device to increase, when the front wheel of the straddle type vehicle in a wheelie state lands on a ground. The control unit controls the damping force to increase, after the front wheel lands on the ground and an oscillation occurs in the steering mechanism.

Straddle type vehicle and control device

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.

Estimation device, vehicle, and estimation method

A vehicle height adjusting apparatus according to one aspect includes: a vehicle height adjusting member that adjusts height of a seat of a saddle-type vehicle, using hydraulic pressure; an oil supplying portion that supplies oil to the vehicle height adjusting member, using a motor; and a control section that estimates a load applied to the vehicle height adjusting member, from a current supplied to the motor and a stroke correspondence quantity of the vehicle height adjusting member, and controls the oil supplying portion based on the load to adjust the height of the seat.

Vehicle height adjusting apparatus

A distributed processing method for executing partial order delivery of data on a plurality of computers connected via a network, the distributed processing method includes receiving the data by the plurality of computers. An output order in which the data is output by the partial order delivery is determined by the plurality of computers. The data to be output by dividing the data into a plurality of subsets equivalent among the plurality of computers and then stored in the output set.

Distributed processing method, distributed processing system, and server

A computer, which is communicably connected to a plurality of computers having respective storage areas for storing data and in which second data that is replication of first data arranged in a storage area of own computer is arranged in storage areas of other computers, and the computer holds capacities of the storage areas of the respective computers and determines first data ranges for arranging the first data in the storage areas of the own computer and the plurality of other computers in accordance with the capacities, determines a second data range that is a largest data range or has a largest capacity, with, as a starting point, a data range that is different from a largest data range or a data range having a largest capacity in the first data ranges, and arranges the data in the storage areas of the respective computers.
