A leaning vehicle including a vehicle body, a steerable front wheel set swivelable around an axis extending in an up-down direction, a rear wheel set, a turn operation input device that receives a turn operation and transmits the turn operation non-mechanically, a leaning device including a lean actuator that leans the vehicle body, the steerable front wheel set and the rear wheel set to a leftward or rightward direction, and a centripetal force generator including a centripetal force generation actuator, which outputs a controllable torque to thereby generate an additional centripetal force that acts on the steerable front wheel set and the rear wheel set during a turn of the leaning vehicle. The controller controls the torque while controlling the lean actuator in accordance with the received turn operation, to thereby control a leaning condition of the vehicle body during the turn and to control generation of the additional centripetal force.

Leaning vehicle with a steerable front wheel

A vehicle is provided with a vehicle body, N (N is an integer equal to or larger than 2) wheels including one or more front wheels and one or more rear wheels, a force generator, and a force controller. The N wheels include one or more turn wheels turnable in the width direction of the vehicle. The force generator is configured to generate a force which changes a yaw angular acceleration. The force controller is configured to control the force generator. A gravity center of the vehicle body is located away from a rotation center of the vehicle toward front side or rear side when the vehicle turns. The force controller controls the force generator to control a roll torque in the width direction acting on the vehicle body.

Vehicle

A leaning vehicle, including a vehicle body, one steerable front wheel and two rear wheels, or two steerable front wheels and one or two rear wheels, a suspension mechanism, a steering mechanism, a steering controller, and an up-down direction acceleration detector attached to the vehicle body or the suspension mechanism. The two steerable front wheels or the two rear wheels are arranged side by side to form a left-right pair of wheels. The up-down direction acceleration detector detects an acceleration in an up-down direction of the leaning vehicle or the vehicle body, generated as one wheel in the left-right pair of wheels passes a bump or a pothole in a road. The steering controller so controls the one or two steerable front wheels that the one or two steerable front wheels are in a free-steering state, so as to swivel around a steering axis freely, based on the detected acceleration.

Leaning vehicle with a left-right pair of wheels

A vehicle small in width and capable of ensuring both driving stability and drivability includes: a vehicle body with two or more wheels including steered wheels (right front wheel, left front wheel) for steering; an inclination angle detection part that detects the inclination angle of the vehicle body about a roll axis thereof; and a torque applying part (turning mechanism) that applies a steering torque to the steered wheels in accordance with an inclination angular velocity or an inclination angular acceleration of the vehicle body calculated from the inclination angle.

A base station includes a transmission unit. The transmission unit transmits, to at least one communication terminal(s), first control information for instructing the at least one communication terminal(s) to perform CSI (Channel State Information) reporting and second control information for making each of the at least one communication terminal(s) determine whether to respond to the instruction to perform the CSI reporting.

Base station, communication terminal, and wireless communication method

In order to improve accuracy in estimating a transmission line that includes a delay path having a long delay time, the present invention provides a wireless reception device that includes a transmission estimation unit including: a delay profile generation unit that estimates a transmission line from a reference signal portion by using a known reference signal replica, and that calculates a delay profile from a transmission line estimation result; a path detection unit that detects a position of a sample, which is included in the delay profile, as a path position; a delay profile division unit that divides the delay profile based on the path position; and a transmission line calculation unit that calculates a transmission line per path by carrying out averaging to the delay profile per path in the frequency domain, and that combines transmission line calculation results per path.
