In some examples, a vehicle suspension for supporting, at least in part, a sprung mass, includes a damper connected to the sprung mass, the damper including a movable piston. The vehicle suspension further includes an actuator and a controller. The controller may be configured to determine a frequency of motion associated with the sprung mass. When the frequency of motion is below a first frequency threshold, the controller may send a control signal to cause the actuator to apply a deceleration force to the sprung mass. Further, when the frequency of motion associated with the sprung mass exceeds the first frequency threshold, the controller may send a control signal to cause the actuator to apply a compensatory force to the sprung mass. For instance, a magnitude of the compensatory force may be based on a friction force determined for the damper.

A vehicle compelling force detection apparatus includes one or more processors configured to: obtain, from a first sensor, a road surface disturbance force received from a road surface on which the vehicle drives via a wheel of the vehicle, and store the road surface disturbance force in one or more memories, the first sensor being disposed below a damper supporting the wheel in a direction of gravity; obtain, from a second sensor, a body disturbance force applied to the vehicle, and store the body disturbance force in the one or more memories, the second sensor being disposed above the damper in the direction of gravity; and detect the compelling force due to the wind disturbance to which the vehicle is subjected, based on the body disturbance force applied to the vehicle and the road surface disturbance force, which are stored in the one or more memories.

A vehicle includes an electric machine, an engine, an engine mount, and a controller. The engine has a base speed that corresponds to a speed of the electric machine and an engine power demand. The engine mount is disposed between the engine and a vehicle structure such as a frame or unibody. The controller is configured to, in response to compression of the engine mount, increase an engine speed to a value that is greater than the base speed to reduce engine lugging.

The present invention obtains a control system and a control method capable of appropriately suppressing front lift-up of a straddle-type vehicle.

In the control system and the control method according to the present invention, damping forces of suspensions and drive power generated to the straddle-type vehicle are controlled. The drive power adjustment control is executed to adjust the drive power generated to the straddle-type vehicle so as to suppress the front lift-up that causes a front wheel of the straddle-type vehicle to lift off from the ground, and initiation timing of the drive power adjustment control is controlled by using a physical quantity to which states of the suspensions are reflected.

Technologies and techniques for operating an assistance system in a motor vehicle with which a driving a shoulder by the motor vehicle is detected by means of at least one detection device in the assistance system, and with which a control signal is generated by means of an electronic computing device in the assistance system for engaging with a functional unit in the motor vehicle. The shoulder that is detected is evaluated in terms of the type of shoulder, and a critical or non-critical driving of the vehicle on the shoulder is determined on the basis of the type of shoulder, and the control signal is generated in the case of a critical driving on the shoulder. The present disclosure also relates to an assistance system.

The present invention relates to a method for determining a desired speed of a vehicle (1), preferably an autonomous vehicle. The vehicle comprises a shock absorber arrangement (2), preferably an hydraulic shock absorber arrangement, having an elastic hysteresis. The method comprises—obtaining (501) a reference value indicative of the energy dissipated by the shock absorber arrangement (2) in a reference driving condition of a vehicle and—determining (502) a speed of the vehicle for which the value indicative of the energy dissipated by the shock absorber arrangement (2) in a similar driving condition is expected to fall within a predetermined energy dissipation range, using said reference value.

A control unit for a vehicle is designed to detect movement sensor data with regard to a movement of at least one component of the vehicle. The movement is or has been effected by a roadway driven upon by the vehicle. In addition, the control unit is designed to detect a lane boundary of the roadway on the basis of movement sensor data and, in reaction thereto, to cause a functional reaction of the vehicle.

Methods, apparatus, systems and articles of manufacture are disclosed to determine vehicle trailer weight. An example apparatus includes a first sensor disposed on a hitch coupled to a vehicle to measure a first rate of change of a weight of the vehicle. The example apparatus also includes a second sensor disposed on a chassis of the vehicle to measure a second rate of change of the weight of the vehicle. The example apparatus also includes a controller to monitor the first rate of change and the second rate of change to determine if the vehicle is improperly loaded.
