Abstract: An active suspension control system for a vehicle includes a mathematical model based on a modal expansion of the vehicle. Model parameters of the vehicle can be extracted from the modal expansion using sensor data generated on the vehicle, e.g., on demand and/or in real time. The model parameters and the modal expansion can be used to determine a vehicle state, predict future vehicle states, and control aspects of an active suspension system based on the predicted future vehicle states. The model parameters may also be used to update the mathematical model, e.g., to account for component wear over time, and/or to detect anomalies or defects in the active suspension system.

Abstract: A seat for a vehicle may include a seatback including one or more inflatable bladders that may be configured to provide adjustable lumbar support and to deploy in response to a triggering event signal indicative of a change of velocity, collision, or predicted collision event. One or more inflatable bladders may be configured to be independently controllable and configured to provide adjustable lumbar support at a region of the seatback during normal vehicle operation. Moreover, when at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback due to the event, the one or more inflatable bladders may be configured to compress at least partially a comfort foam or comfort material in the seatback and expedite engagement of the energy absorbing material with the occupant's back.

Abstract: The invention concerns a tank (1) for a motor vehicle comprising an outer casing (10) delimiting an inner volume, the casing (10) comprising two portions, a bottom portion (19) and a cover portion (18), securely attached to each other in a sealed manner, characterised in that said casing (10) comprises an inner partition (40) made in one piece with the casing (10), said partition (40) separating the inner volume into two sealed compartments (20 and 30), which inner separating partition (40) extends from the bottom portion (19) and the cover portion (18). The invention also concerns a motor vehicle comprising such a tank.
