An air suspension system for a vehicle comprises four corner assemblies, wherein one corner assembly is located at a suspension position corresponding to each of the wheel corners for the vehicle. An air supply unit including a compressor, and an ECU are connected to the corner assemblies. The air supply unit is capable of independently adjusting the corner assemblies from one another. A sensor for measuring jounce/rebound travel for a wheel is associated with each of the corner assemblies and the air suspension system is operable adjust the air pressure at each of the four corner assemblies to provide optimized traction for the vehicle when at least one of the wheels has a predetermined amount of travel.

In a method for operating a wheel suspension system of a motor vehicle, a sensor checks the ground for the presence of an obstacle, as identified by a control device, and predicts for the obstacle a first value for an amount of electrical energy, which is to be converted from mechanical energy by an electrical machine, when a damping ratio is set with a defined recuperation value for a damper connecting a wheel to a chassis. The control device predicts a second value for a ride comfort and determines a third value for a decision criterion, which is a function of the first and second values. The identified obstacle is to be driven over with the recuperation value set for the damping ratio of the damper, when the value for the decision criterion corresponds to a target value.

A computer-implemented method for damping a vehicle, including: receiving external load data for the vehicle; receiving at least one damper velocity of a damper of the vehicle; providing an optimization model configured to describe a relation between external load data for a vehicle, at least one damper velocity of a damper of a vehicle, and at least one damper force of the at least one damper; determining at least one damper force of the damper for the vehicle by inputting the external load data and the at least one damper velocity into the optimization model; and providing the at least one damper force of the at least one damper of the vehicle.

A method for loading a trailer comprising: providing a trailer having at least two axles connected to a trailer chassis by independently adjustable suspension systems, the at least two axles including a frontmost axle and a rearmost axle, the trailer further comprising a kingpin configured to be removably connected to a fifth wheel of a tractor; a first loading step comprising loading the trailer until a threshold load is reached on the kingpin; and then a second loading step comprising: loading the trailer further; and adjusting a suspension parameter of the rearmost axle to ensure that the load on the kingpin remains at or below the threshold load.

A control system (300) for controlling an active suspension system (104) of a vehicle (100), the active suspension system comprising suspension actuators (502), the control system comprising one or more controller (301), wherein the control system is configured to: in dependence on an activation signal (904), provide (908) a control signal to the active suspension system to cause the suspension actuators of the active suspension system to repetitively pulse vertical force through wheels (FR, FL, RR, RL) of the vehicle in a controlled pattern determined by the one or more controller, to vary wheel-to-surface contact patch forces, wherein the pattern comprises repetitively pulsing vertical force through at least one of the wheels at a first phase and through at least one other of the wheels at a second phase.

A computer system controls a vertical load on a coupling between units of a vehicle combination comprising a trailing unit and a preceding unit. The trailing unit has two or more axles and is coupled to the preceding unit via the coupling. The computer system has processing circuitry to acquire a current value of a vertical load on the coupling; determine a coupling load capability based on the current value of the vertical load on the coupling and a current value of a virtual wheelbase of the trailing unit; and determine a desired vertical load on the coupling based on the coupling load capability.

A computer-implemented method for controls stability of a vehicle, being a truck or tractor and at least one trailer comprising at least two wheel axles and an electronically controllable suspension system. The method identifies a possible instability state of the vehicle; determines a type of an event that has caused the possible instability state; determining one or more actions comprising adjusting a load distribution between the at least two wheel axles of the trailer based on the possible instability state and based on the type of the event that has caused the possible instability state; and generates and sending a control command to the suspension system to perform the actions. The actions may comprise adjusting the load distribution between the at least two wheel axles of the trailer such that a load on a rear axle is increased and a load on a front axle is decreased.

A system for vehicle load management including a processor and a memory in communication with the processor and including instructions that, when executed by the processor, cause the processor to receive a first indicator signal from a first sensor. The instructions further cause the processor to, based at least in part to the first indicator signal, determine a vehicle load intervention. The instructions further cause the processor to, based, on the vehicle load intervention, transmit one or more adjustment signals to cause one or more vehicle load adjustments to occur, the one or more vehicle load adjustments including at least one of at least one lire being inflated, the at least one tire being deflated, a liftable axle being raised, and the liftable axle being lowered.
