A method for the automated control of the longitudinal movement of a motor vehicle having an automated positive acceleration process in a longitudinal direction of the vehicle and an automated deceleration in the longitudinal direction of the vehicle. An acceleration variable is determined based on a jerk value and limited in terms of absolute value. And the jerk value is in turn determined in a driving mode in which, starting from a vehicle actual longitudinal speed and a vehicle actual longitudinal acceleration, the motor vehicle is adjusted to a predeterminable vehicle longitudinal speed taking into account a predeterminable maximum positive driving mode vehicle longitudinal acceleration, a predeterminable maximum driving mode vehicle longitudinal deceleration and at least one predeterminable driving operating mode jerk absolute value which limits the jerk.

An autonomous guided vehicle comprising a platform adapted to carry a load thereon in a working position; a plurality of suspension devices connected to the platform, each suspension device having a sensor and an actuator; and a plurality of wheels associated with the suspension devices; wherein a first wheel is associated with a first suspension device such that the sensor of the first suspension device is adapted to provide a signal when a relative position of the first wheel and the platform is altered.

A work vehicle including: a first link having one end portion supported by a vehicle body so as to be pivotable; a second link having one end portion pivotally coupled to the other end portion of the first link so as to be pivotable, and another end portion that supports a travel wheel; a first hydraulic cylinder capable of changing a swing posture of the first link; and a second hydraulic cylinder capable of changing a swing posture of the second link relative to the first link. The action of the first hydraulic cylinder is controlled such that a swing position of the first link is located at a target position, based on the result of detection performed by a position detection sensor, and the action of the second hydraulic cylinder is controlled such that thrust has a target value, based on the results of detection performed by pressure sensors.

A vehicle includes a vehicle body, at least one wheel includes an annular tire that rotates to drive the vehicle body along a main driving direction, a wheel gear disposed on an inner surface of the tire, and an in-wheel actuator that is connected to the wheel gear and that rotates to rotate the tire, and positioning devices that are fixed to the vehicle body and that rotate the at least one wheel relative to the vehicle body to change positions of the at least one wheel relative to the vehicle body, the at least one wheel being coupled to at least one positioning device so as to be rotatable.
