Control of a suspension component of a vehicle
10974563 · 2021-04-13 · ·

A method for controlling a suspension component of a vehicle, in which a control unit of the suspension component continuously generates a plurality of control requirements according to a generation clock frequency, each requirement comprising a control value, for an actuator of the suspension component. A bus system of the vehicle continuously transmits to the actuator the control requirements generated by the control unit according to a transmission clock frequency. The actuator calculates a target output value for the suspension component from the control value of each transmitted control requirement and an actual output value of the suspension component, and adjusts the suspension component corresponding to the calculated target output value.

Method and apparatus for controlling an actuator

At least one controller configured to control an actuator of an active suspension system. The at least one controller includes circuitry configured to determine an actuator state, and apply the actuator state and a commanded state to an inverse model of the actuator to produce an actuator command. The circuitry is configured to produce the actuator command by a process that includes performing low pass filtering and phase compensation to correct a phase introduced by the low pass filtering.

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.

Control device of a vehicle suspension

A control device of a vehicle suspension has a suspension device mounted between a supporting vehicle structure and a vehicle part that is movably mounted. The control device includes a blocking device for blocking a compression or rebound motion occurring at the suspension device in correspondence with a blocking command transmitted to a control unit. The control unit determines a characteristic weight value for a current loading of the suspension device when the blocking command is set and stores it as a pertinent value in a memory unit. The control unit determines a value for the weight when the blocking command is reset in order to cancel a blocking of the suspension device according to the result of a comparison with the value stored in the memory unit.

Method for Efficiently Transmitting a Road-Surface Contour Profile
20180186210 · 2018-07-05 · ·

A method for transmitting information between a motor vehicle and a vehicle-external server. A contour profile of a road to be traveled along by the vehicle, which is stored on the server, is retrieved by the vehicle via a vehicle-server interface. The contour values of the road contour profile lying ahead of the vehicle are cyclically transmitted by the server to the vehicle at a definable interval. A contour value is transmitted per cycle, which lies ahead of the vehicle at a speed-dependent interval. In addition, a chassis system for carrying out the method and a vehicle are provided with the chassis.

A signal level detection device 1 and a signal level detection method according to a means for solving a problem of the present invention varies a cut-off frequency c, of a variable low-pass filter 3 which filters a signal level r. The cut-off frequency c is varied based on the signal level r or information referred to for estimating the signal level. The signal level detection device 1 and the signal level detection method therefore reduce a delay of a rise of the obtained signal level r from an actual signal level, and sufficiently remove noise superimposed on the signal level r even when the signal level r is extremely low. Accordingly, control performance improves regardless of a degree of the signal level r.
