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 suspension apparatus includes: a damping device which damps a force generated between a vehicle body and a wheel; and a control section which controls a damping force of the damping device. The control section includes a multiplication section which multiplies a longitudinal acceleration of the vehicle body detected by a longitudinal acceleration sensor and a differential value of the longitudinal acceleration to thereby obtain a multiplication value.

A method, apparatus and vehicle for controlling a ride level for a vehicle having at least one first axle having a first air suspension and/or one second axle having a second air suspension, a parking brake and an operating brake, including: reading a ride level variation signal, indicating a ride level variation to be performed; providing a parking break release signal to an interface to a parking brake valve that, responding to the ride level variation signal, releases and engages the parking brake installation, the parking brake release signal being for actuating the parking brake valve for releasing the parking brake installation; and providing a first control signal to an interface to a first valve of the first air suspension and/or a second control signal to an interface to a second valve of the second air suspension while using the ride level variation signal for performing the ride level variation.

A vehicle with suspension-controlled motion resistance members is provided. The vehicle includes a body and a chassis coupled to a base of the body. The vehicle further includes a motion resistance member that is coupled to a base surface of the chassis, a wheel assembly coupled to the chassis, and a suspension unit coupled to the wheel assembly and the chassis. In an actuated state, the suspension unit is configured to move the chassis in a first direction until at least a portion of the motion resistance member contacts a ground below the base surface of the chassis.

This vehicle control device is provided with: a control unit for executing one-pedal control, that is, the control for accelerating a vehicle when a single pedal is depressed from a predetermined reference point of a pedal stroke, and for decelerating the vehicle when the pedal is released from the reference point; and a determination unit for determining whether or not a rate of change in a pedal operation amount when the pedal is released is equal to or greater than a first threshold value. The control unit performs control for increasing a braking force when the rate of change is equal to or greater than the first threshold value.

A shock-absorbing front fork assembly of a motorcycle includes a front fork, a pressure buffering cylinder and a control valve disposed between the front fork and the pressure buffering cylinder and electrically connected with a brake system to control the communication between the front fork and the pressure buffering cylinder according to the operation of the brake system. When the brake system is not actuated, the control valve is open to make the front fork communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively smaller. When the brake system is actuated, the control valve is close to make the front fork not communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively larger. Therefore, the spring supporting force is adjusted by the brake operation, that raises the riding comfort and safety.
