Systems, computer-implemented methods, and computer program products relating to jerk of a vehicle damper are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a control signal determination component that determines a new damping coefficient for a vehicle damper and determines a rate of change of acceleration from a current damping coefficient of the vehicle damper to a new damping coefficient for the vehicle damper, wherein the rate of change is based on a movement signal of the vehicle damper, and a damper adjustment component that adjusts to the new damping coefficient at the rate of change.

The present disclosure discusses a method of operating a vehicle having a set of tires and an active suspension system. The method includes operating the vehicle to travel along a road surface, sensing, using a smart tire assembly, a magnitude of one or more physical quantities associated with at least one tire of the set of tires, and controlling the active suspension system of the vehicle based at least in part on the magnitude of the sensed one or more physical quantities.

A regulator for establishing outlet fluid pressure. The regulator includes a valve body having a fluid pressure inlet in selective fluid communication with a fluid pressure outlet. A pilot pressure inlet is formed in the valve body and in fluid communication with a source of pilot pressure. Valving structure in the valve body establishes outlet fluid pressure as a function of pilot pressure. First adjustable structure within the valve body may establish a minimum outlet fluid pressure threshold without regard to pilot pressure. Second adjustable structure within the valve body may establish outlet fluid pressure offset relative to pilot pressure.

A wireless active suspension system is disclosed. The system includes at least one sensor mounted to an unsprung mass of a vehicle, the sensor having a low power wireless communication capability, the at least one sensor to send a sensor data transmission. The system also includes a controller in wireless communication with the at least one sensor, wherein the controller receives the sensor data from the at least one sensor and communicates an adjustment command to modify at least one damping characteristic of at least one damper.

The present invention relates to a control unit for determining a value indicative of a load bearing capability of a ground segment supporting a vehicle. The control unit is configured to issue a control signal to the vehicle to thereby impart a motion change of the vehicle, and receive response information from the vehicle indicative of the vehicle's response to the imparted motion change. The control unit is further configured to, based on the response information, determine a vertical position change of at least one wheel of the vehicle, and based on the determined vertical position change and the imparted motion change, determine the value indicative of the load bearing capability of the ground segment.

A suspension control device which controls an operation of a suspension of a vehicle includes an operation-induced state quantity estimation portion which estimates an operation-induced state quantity caused by an operation of a vehicle, a road surface-induced state quantity estimation portion which estimates a road surface-induced state quantity caused by a road surface, an operation-induced state quantity conversion portion which converts the operation-induced state quantity into an operation-induced required damping force, a road surface-induced state quantity conversion portion which converts the road surface-induced state quantity into a road surface-induced required damping force, and a current value calculation portion which determines a current value to be applied to the suspension with reference to the operation-induced required damping force and the road surface-induced required damping force.

The present invention relates to an automatic lift system for a pusher axle and/or a bridge axle of a truck. The automatic lift system raises the pusher axle and/or the bridge axle in the event of a tire blowout or low tire pressure to prevent the truck from swerving, spinning out or rolling over. The system includes a tire pressure sensor integrated to each of two wheels connected to the pusher axle and each of the two wheels connected to the bridge axle. Each tire pressure sensor is connected to a wired circuit and controller area network (CAN) of the truck for electronic communication with a control box. The control box receives tire pressure information from the sensors and transmits axle lift instructions in response to the tire pressure.

Systems, methods, and computer-readable storage media for using multi-stage machine learning algorithms to optimize tire contact patches on a vehicle. Vehicle sensors first collect vehicle information for the vehicle, and input that data into a first machine learning algorithm. The first machine learning algorithm then outputs a lateral dimension, a longitudinal dimension, and a diagonal dimension, which together identify a tire contact patch of at least one tire on the vehicle. The operator of the vehicle provides a human preference for how the vehicle operates, and a second machine learning algorithm is executed. The second machine learning algorithm inputs can include the plurality of vehicle information, the first machine learning algorithm outputs, and the human preference, and the second machine learning algorithm outputs can include a desired tire pressure of the at least one tire and an air suspension adjustment for the normal load of the vehicle.

In one embodiment, a control system for a vehicle comprising an axle having a center pivoting axis and a frame coupled to the axle at the center pivoting axis, the control system comprising: one or more controllers; a control circuit; and one or more actuators located on one side or opposite sides, respectively, of the center pivoting axis and coupled to the axle and the frame of the vehicle, the one or more actuators configured by the one or more controllers and the control circuit to prevent tipping based on forces imposed on the vehicle.

A vehicle height adjusting device includes a vehicle height adjusting unit, a prediction unit, and a vehicle height control unit. The vehicle height adjusting unit adjusts a vehicle height to one of a first state and a second state. In the first state, the vehicle height is set to a predetermined height, and in the second state, the vehicle height is set lower than the first state. The prediction unit predicts whether a drive battery (lower portion) of a vehicle interferes with a road surface in the second state. The vehicle height control unit controls the vehicle height adjusting unit to set the vehicle height to one of the first state and the second state. When the prediction unit predicts an interference between the drive battery of the vehicle and the road surface, the vehicle height adjusting unit restricts a transition from the first state to the second state.
