Method For Operating A Motor Vehicle, Method For Roll Compensation Of A Motor Vehicle, And Motor Vehicle
A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.
SITUATION DETECTION IN ACTIVE SUSPENSIONS
A method for controlling an operating mode of a controller for at least one suspension component of an at least partially active suspension of a vehicle. In accordance with at least one control command provided by a user for steering the vehicle, a situation detection is carried out to detect a control situation in which the at least one suspension component of the suspension which should be at least partially actively controlled, can be potentially controlled, and in the event that a control situation is detected, at least one reactive controller for controlling the at least one suspension component is switched from a first operating mode to a second operating mode, the at least one reactive controller being switched into the second operating mode with an increased bandwidth and amplification when compared with the first operating mode.
Method for providing a manipulated variable
The invention relates to a method for providing a manipulated variable for an actuator (4) of an active chassis of a motor vehicle (2), wherein the manipulated variable in the event that a value for a projected variable, which is dependent upon a height profile of the terrain to be travelled by the motor vehicle (2), is available, is configured from a combination of a Skyhook variable, which is dependent upon a movement of a structure of the motor vehicle (2), and the projected variable, and wherein the manipulated variable is configured from a combination of a soft-spring variable, which is dependent upon a wheel-suspension of the motor vehicle (2), and the Skyhook variable, if no value for the projected variable is available.
Method Of Operating A Motor Vehicle, And Motor Vehicle
A method of operating a motor vehicle with a chassis system comprising at least two, preferably four vibration damper includes carrying out a body control and a wheel control with the chassis system, and controlling the energy supply for the chassis system via an energy control arrangement. A motor vehicle performing the method is also disclosed.
START-UP AND SHUTDOWN FOR ACTIVE SUSPENSION SYSTEM
A control system (100, 200) for a vehicle suspension system of a vehicle (900) is disclosed. The control system is configured to: determine that the vehicle is operating in a precondition state in dependence on an actuator power supply status; and output a first damping control signal to an adaptive damping system of the vehicle in dependence on the determination. The first damping control signal is configured to cause the adaptive damping system to activate a first damping control mode in which a predetermined level of damping is provided to the vehicle.
ACTIVE VEHICLE SUSPENSION
A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.
Method for operating a wheel suspension system
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.
