A vehicle is provided including an electronic power steering system, an electronic throttle control system, and a stability control system.

An agricultural vehicle is provided herein that includes a chassis operably coupled with a powertrain control system. A boom assembly is operably coupled with the chassis. One or more nozzles is positioned along the boom assembly. A flow control assembly is configured to selectively dispense an agricultural product from a tank through the one or more nozzles. A controller is operably coupled with the powertrain control system and the boom assembly. The controller includes a processor and associated memory with the memory storing instructions that, when implemented by the processor, configure the controller to receive instructions to accelerate or decelerate the vehicle and alter a flow rate of the agricultural product through actuation of the flow control assembly in response to receiving instructions to accelerate or decelerate the vehicle.

A vehicle suspension damper is described. The vehicle suspension damper includes: a pilot valve assembly; a primary valve; and an adjuster, wherein the pilot valve assembly meters fluid to the primary valve, and the adjuster moves the primary valve.

A suspension device includes: a damping device that damps a force generated between a vehicle body and a wheel of a vehicle; a determination unit that determines whether the vehicle is jumping, using an acceleration of the vehicle in a front-rear direction, an acceleration of the vehicle in a left-right direction, and an acceleration of the vehicle in a vertical direction; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when the determination unit does not determine that the vehicle is jumping, when the determination unit determines that the vehicle is jumping.

A vehicle includes a first actuator, one or more second actuators, and an electronic control unit. The first actuator is configured to control a stroke of a suspension for a control target wheel. The one or more second actuators is configured to control the stroke of the suspension and more responsive than the first actuator. The electronic control unit is configured to: execute a calculation process to calculate a required control amount for at least one of roll control and pitch control of the vehicle; and execute a command process to distribute and command the required control amount to the first actuator and the one or more second actuators.

A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.

The anti-dive control method for the automobile comprises: obtaining preset automobile operating condition parameters, and obtaining parameter values of the automobile operating condition parameters in real time; determining in real time whether the parameter values of the automobile operating condition parameters satisfy a preset first trigger condition or a preset second trigger condition; if the parameter values of the automobile operating condition parameters satisfy the preset first trigger condition, obtaining a preset first control strategy corresponding to the first trigger condition; implementing real-time control of the suspension damping force of the automobile according to the first control strategy; if the parameter values of the automobile operating condition parameters satisfy the preset second trigger condition, obtaining a preset second control strategy corresponding to the second trigger condition; and implementing real-time control of the suspension damping force of the automobile according to the second control strategy.

The present invention obtains a controller capable of suppressing worsening of comfort of an occupant in a vehicle when compared to the background art.

The controller according to the present invention is a controller that is mounted to the vehicle and outputs a command signal corresponding to a damping coefficient of a shock absorber to an actuator that adjusts the damping coefficient of the shock absorber of a damping force adjustment type. In the case where, in the vehicle, a portion on a wheel side with the shock absorber being a reference is set as an unsprung portion, where a state where a frequency of the unsprung portion is higher than a prescribed frequency is set as a first frequency state, and where a state where the frequency of the unsprung portion is lower than the prescribed frequency is set as a second frequency state, the controller is configured to output, to the actuator, such a command signal that reduces the damping coefficient of the shock absorber to be smaller than the damping coefficient of the shock absorber in the second frequency state when a state becomes the first frequency state.

A suspension control system for a vehicle may include a plurality of adjustable dampers associated with suspension of respective ones of a plurality of wheels of the vehicle, a controller operably coupled to the adjustable dampers to selectively adjust a damping force of one or more of the adjustable dampers responsive to an activation signal, and a driver interface disposed at a steering wheel assembly of the vehicle. The driver interface may be actuated by a driver of the vehicle to apply the activation signal while the driver interface is actuated.

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.
