    Abstract: A control system calculates inputs to a control target that has m inputs and n outputs (m=n, each of m and n is a natural number that is more than one), while designating a plurality of combinations of the inputs and the outputs. A feedback controller calculates, with respect to each designated combination, a control input to a non-interference controller based on a difference between a target value and a current value of the control quantity to make the current value follow the target value. The non-interference controller executes, with respect to each designated combination, a non-interference control to reduce influence due to mutual interference between n control quantities. This reduces the number of combinations of the inputs and the outputs, the combinations whose mutual interference needs considering; thereby, the non-interference control may be easily achieved.

The one or more actuators are configured to receive an input from the driver to control or actuate one or more associated vehicle systems. In response to detecting the deactivation condition, the techniques include deactivating or disabling, by the controller, the one or more actuators of the steering wheel until the deactivation condition is no longer present.

  • Patent number: 9416841
    Abstract: A method and apparatus are disclosed for cooling damping fluid in a vehicle suspension damper unit. A damping unit includes a piston mounted in a fluid cylinder. A bypass fluid circuit having an integrated cooling assembly disposed therein is fluidly coupled to the fluid cylinder at axial locations that, at least at one point in the piston stroke, are located on opposite sides of the piston. The cooling assembly may include a cylinder having cooling fins thermally coupled to an exterior surface of the cylinder and made of a thermally conductive material. The bypass channel may include a check valve that permits fluid flow in only one direction through the bypass channel. The check valve may be remotely operated, either manually or automatically by an electronic controller. A vehicle suspension system may implement one or more damper units throughout the vehicle, controlled separately or collectively, automatically or manually.

  • Patent number: 9394965
    Abstract: An absorber system for a vehicle includes a controller. The controller determines a reference control amount as a reference of a target control amount which is a target of a control amount for controlling a damping force with respect to an operation of a cylinder in its extension and an operation of the cylinder in its compression. The controller determines the target control amount to the reference control amount for one of the operation of the cylinder in its extension and the operation of the cylinder in its compression and determines the target control amount to a value obtained by multiplying the reference control amount by an extension-compression gain for the other. The controller changes the extension-compression gain in at least one of a driving-stability-emphasized situation in which driving stability is to be emphasized and a ride-comfort-emphasized situation in which ride comfort is to be emphasized.

  • Patent number: 9283824
    Abstract: A method for controlling a torque of a roll stabilizing system which acts on a wheel suspension system of a chassis for a vehicle in order to correct a rolling inclination of the bodywork of a vehicle, wherein a spring travel value of at least two wheels of the vehicle is detected. The torque is determined as a function of a difference between the spring travel values of the two wheels, and the determined torque is applied to the wheel suspension system. An actual torque which acts on the wheel suspension system is preferably determined on the basis of the differences between the spring travel values. The actual torque is used to calculate a setpoint torque for a roll stabilizing system.
