A Kalman filter in a roll angle estimation device estimates a roll angle of a vehicle body, a vehicle speed, a roll angular velocity sensor offset, a yaw angular velocity sensor offset, and a vertical acceleration sensor offset on the basis of detected values of a roll angular velocity sensor, a yaw angular velocity sensor, a vertical acceleration sensor, a longitudinal acceleration sensor, a lateral acceleration sensor, and a rear-wheel speed sensor, and also on the basis of estimated values of the roll angle, the vehicle speed, the roll angular velocity sensor offset, the yaw angular velocity sensor offset, and the vertical acceleration sensor offset obtained in a previous estimation operation.

Roll angle estimation device and transport equipment

An attitude controller eliminates a skid motion of a banked vehicle when travelling through a curve. The attitude controller includes a lateral acceleration sensor that obtains lateral acceleration, as rightward or leftward accelerations, acting on a vehicle of a motorcycle, a bank angle detector that detects a bank angle of the vehicle, and a longitudinal force controller that decreases, independently of each of the wheels, an absolute value of a longitudinal force as the sum of forward and backward forces acting on front and rear wheels based on the obtained lateral acceleration and the detected bank angle.

A two-wheeled motor vehicle includes a control device and is configured such that a radius of curvature of a cross-section of a tire mounted on one of the front wheel and the rear wheel is larger than a radius of curvature of a cross-section of a tire mounted on the other wheel. The control device includes a sensor arranged to detect a rotation speed of the one wheel, a sensor arranged to detect a rotation speed of the other wheel, and a turn determining section programmed to determine that the vehicle is turning based on a condition that a value corresponding to a bank angle of the vehicle is higher than a threshold. The value corresponding to the bank angle of the vehicle is a value indicating the relative amount of the rotation speed of the one wheel relative to the rotation speed of the other wheel.

Two-wheeled motor vehicle and control device therefor

Provided is a longitudinal force control apparatus. A lateral acceleration acquisition section acquires a lateral acceleration along a right-left direction acting on a vehicle. A bank angle acquisition circuit acquires a bank angle of the vehicle. A longitudinal force controller may decrease an absolute value of a longitudinal force at least with respect to a driving wheel of the vehicle based on the acquired lateral acceleration and the bank angle when it is determined that a calculated lateral-skid acceleration is equal to or greater than a predetermined threshold. The longitudinal force is a sum of forces along a front-rear direction acting on the driving wheel.

A brake hydraulic pressure control apparatus is provided with wheel cylinder pressure inference value acquisition means (step) for acquiring an inference value of the wheel cylinder pressure, master cylinder pressure inference value acquisition means (step) for acquiring an inference value of the master cylinder pressure by utilizing a wheel cylinder pressure inference initial value, reaction force compensation amount acquisition means (step) for acquiring a reaction force compensation amount which is a value depending on the variation of the master cylinder pressure caused by the flowing of brake fluid during an ABS control, and differential pressure inference value acquisition means (step) for acquiring an inference value of the differential pressure between the master cylinder pressure and the wheel cylinder pressure by adding the reaction force compensation amount to the difference between the master cylinder pressure inference value and the wheel cylinder pressure inference value.
