A steering application executing on a vehicle control module receives a steering control input to control a steered wheel of a vehicle and, based on the steering control input, determines a setpoint value for the steered wheel. A diagnostic supervisor receives a measured value of the control attribute and the setpoint value; wherein the first diagnostic supervisor comprises a first model of a steering system of the vehicle. Based on the setpoint value and the first model, the diagnostic supervisor calculates a virtual value of the control attribute and, based on the virtual value and the measured value of the control attribute the first diagnostic supervisor determines an operating condition of the steering system of the vehicle.

A vehicle includes a vehicle controller communicating over a first communication system with actuators for changing the state of vehicle systems. A signal module communicates with the vehicle controller via the first communication system. One or more signal sources communicate with the signal module via a second communication system, and transmit signals to the signal module. Based on one or more signals and one or more user inputs, the signal module generates and transmits control signals to the vehicle controller. The vehicle controller actuates the actuator based on the control signal.

An object responsive control system for a work machine having a boom, an attachment pivotally coupled to the boom, an object sensor adapted for sensing the presence of an undesirable object located in a travel path of the work machine and delivering an object signal upon sensing the undesirable object. A controller adapted for receiving a boom position signal, an attachment position signal, and calculating an elevational position based on the boom position signal. The system activating an object response upon calculating an attachment elevation position above a predetermined threshold and receiving an object signal.

The invention relates to a chassis comprising a base (12) and four wheels (14) each being mounted on the base by way of a respective supporting device (16) and each being capable of being brought out of a transport position into an operating position of the chassis (10), and vice versa, wherein each supporting device comprises a support or carrier arm (18), which is arranged on the base via a proximal end (20) to be pivotable out of the transport position into the operating position of the chassis, and vice versa, and at a distal end (22) receives an axle journal (24) for rotation, a first control (30) for pivoting the support or carrier arm out of the transport position into the operating position of the chassis, and vice versa, the axle journal rotatably arranged at the distal end of the support or carrier arm, a stub axle (40), which is pivotably arranged on the axle journal and receives the wheel for rotation at a distal end (42) of the axle journal; and a second control (44) for pivoting the stub axle against the axle journal.

A transport vehicle includes two non-steered drive wheels, two non-driven steered load wheels, drive motors for driving the drive wheels, a steering target value encoder, a device for detecting the steering angle of one of the load wheels, and an electric control unit. An actuation of the steering target value encoder displaces a steering pole along a steering pole axis. The steering target value encoder steers each of the load wheels from a first position in which the load wheels' axes run parallel to the drive wheels' axes into a second position in which the load wheels' axes are oriented to the steering pole which lies between the drive wheels. The electronic control unit influences a rotational speed of the drive motors as a function of the steering angle and reverses a direction of rotation of at least one of the drive motors as a function of the steering angle.

The invention relates to a cargo handling vehicle for handling cargo within narrow aisles. The cargo handling vehicle comprises means for autonomous navigation, a chassis having at least two pairs of ground engaging means, a lifting boom. The lifting boom having a first end and a second end wherein the first end is arranged to the chassis and the second end is provided with a lifting unit. The first end of the lifting boom is attached to the chassis enabling movement of the second end in a vertical and horizontal direction, and the lifting unit is arranged rotatably in a horizontal plane. Each of the ground engaging means are independently steerable and individually driven by a respective driving means. Further, the invention also relates to a method in a cargo handling vehicle.

An intermodal container mobilizer that includes a tow vehicle and forward and aft intermodal shipping container attachments. The forward container attachment is carried by the tow vehicle and connects to one end of an intermodal container. The aft container attachment is wheeled and connects to an opposite end of the intermodal container.
