A damping force control apparatus for a vehicle in which road surface displacement-related information detected by an in-vehicle detection device is transmitted to a preview reference database control device together with detection position information, a preview reference database including road surface displacement-related values is made, preview damping control that reduces vibration of a sprung of the vehicle is performed using the road surface displacement-related values in the preview reference database, and it is assumed that a road surface displacement-related value in a predetermined adjacent region located in a direction crossing a traveling direction of the vehicle with respect to a point where the road surface displacement-related information was detected by the in-vehicle detection device is the same as the road surface displacement-related value at the above point.

A damping force control apparatus for a vehicle in which road surface displacement-related information corresponding to left and right wheels detected by a pair of in-vehicle detection devices is transmitted to a preview reference database control device together with the detection position information, a preview reference database including road surface displacement-related values is created, preview damping control that reduces vibration of a sprung of the vehicle is performed using the road surface displacement-related values in the preview reference database, and it is assumed that road surface displacement-related values in predetermined adjacent regions located in a direction crossing a traveling direction of the vehicle with respect to two points where the road surface displacement-related information was detected by the pair of in-vehicle detection devices are the same as an in-phase component of the road surface displacement-related values at the two points.

A vibration damping control apparatus of a vehicle executes preview vibration damping control for controlling a control force generating apparatus on the basis of a final target control force including a first target control force computed by using preview information. When the vibration damping control apparatus determines that the probability that a road surface condition has changed after a past point in time is high, the vibration damping control apparatus executes particular control for setting the magnitude of the first target control force to become smaller.

A weight sensing assembly for a semi-trailer truck enabling balancing of a load includes a sensing module, which is one of a plurality thereof. The sensing modules are mountable to wheels of the semi-trailer truck so that each axle has a sensing module engaged to outside wheels thereof. The sensing module obtains a pressure measurement of a tire engaged to the wheel and transmits it to an electronic device. Programming code on the electronic device enables it to utilize a pressure changes, upon positioning of a load upon the semi-trailer truck, to determine a weight that is positioned upon an associated axle. The electronic device calculates adjustments to positions of a sliding fifth wheel and of sliding tandems of the semi-trailer truck to obtain positions thereof that will achieve a legal weight distribution of the load. The electronic device presents, upon a screen thereof, the adjustments to a user.

Electromechanical apparatuses for controlling vehicle suspension settings. Described herein are electromechanical apparatuses for controlling wheel alignment (e.g., camber, castor and/or toe). In particular, described herein are camber adjusting apparatuses for electromechanically adjusting camber or camber and toe that may be retrofitted onto existing vehicle suspensions.

A suspension system includes a primary actuator, an inertial actuator, and a controller. The primary actuator applies force between a sprung mass and an unsprung mass of a vehicle to control movement therebetween. The inertial actuator applies force between the unsprung mass and a reaction mass to damp movement of the unsprung mass. The inertial actuator has a threshold capacity. The controller controls the primary actuator and the inertial actuator. The controller determines a required damping of the movement of the unsprung mass, and apportions the required damping between the primary actuator and the inertial actuator.

A vehicle actuator system includes an actuator, a first actuator controller that is operable to control operation of the actuator and is operable to determine a first value for a parameter that relates to operation of the actuator, a second actuator controller that is operable to control operation of the actuator and is operable to determine a second value for the parameter, and at least one additional component that is operable to determine a third value for the parameter. A fault is identified in response to determining that the first value does not agree with at least one of the second value or the third value. In response to identification of the fault, the first actuator controller changes from an activated state to a deactivated state and the second actuator controller changes from a deactivated state an activated state.

An assembly includes a suspension link, an arm, an actuator, and a lock. The arm is connected to the suspension link. The arm includes a plurality of holes. The actuator is connected to the arm. The lock includes a pin releasably engageable with the plurality of holes of the arm.

A powertrain for a vehicle may include a vehicle chassis, a rotatable vehicle drive axle, at least one selectively movable electric propulsion motor having a rotatable motor shaft rotatable about an axis defined by the rotatable vehicle drive axle, a motor actuator connected to the at least one selectively movable electric propulsion motor, and a control system in communication with the motor actuator. The control system may include a memory device in communication with the control system having instructions that when executed by the control system causes the control system to receive at least one input from at least one sensor and instruct the motor actuator to rotate the at least one selectively movable electric propulsion motor based on the at least one input from the sensor.
