An apparatus for controlling cornering of a vehicle includes a control unit configured to receive a plurality of vehicle signals output from the input unit, to output each of damping forces obtained through a plurality of controls performed on the basis of the plurality of vehicle signals, and to output a damping force variation calculated through a cornering control performed on the basis of some of the plurality of vehicle signals, an adjustment unit configured to apply the damping force variation output from the control unit to an integrated damping force and then output a final damping force, and a damping unit configured to receive a changed current signal of the final damping force and then adjust a damping force of a damper. The damping force of the damper of the damping unit is controlled to be reduced when it is determined that the vehicle enters circuit cornering.

An embodiment of the present invention allows for application of an assist torque or reaction torque which causes a driver to feel less discomfort. An ECU (600) includes a rack shaft axial force estimating section (620) configured to estimate a rack shaft axial force with reference to a roll rate of a vehicle body.

Provided is an examination method for a damping force variable mechanism, the examination method including: an operation step of operating a damper in a state in which the damper is installed in a vehicle, the damper being provided with a damping force variable mechanism that changes a damping force according to an input current (an example of a signal); and a detection step of detecting an induction current (an example of an output from the vehicle) from the damping force variable mechanism of the damper installed in the vehicle, wherein a detection device that performs the operation of the detection step is provided. Thus, the damping force variable mechanism of a pressure damping device can be examined in a state in which the damping force variable mechanism is installed in the vehicle.

An active suspension control system for a vehicle includes a mathematical model based on a modal expansion of the vehicle. Model parameters of the vehicle can be extracted from the modal expansion using sensor data generated on the vehicle, e.g., on demand and/or in real time. The model parameters and the modal expansion can be used to determine a vehicle state, predict future vehicle states, and control aspects of an active suspension system based on the predicted future vehicle states. The model parameters may also be used to update the mathematical model, e.g., to account for component wear over time, and/or to detect anomalies or defects in the active suspension system.

A damping system with an actively controllable shock absorber having a first working space and a second working space, which are separated from one another by a piston. A hydraulic pump conveys a hydraulic medium into the first working space or into the second working space. In order to dampen fast compression or rebound movements, the first working space is communicatively connected to a hydraulic reservoir via a first controllable throttle check valve, the second working space is communicatively connected to the hydraulic reservoir via a second controllable throttle check valve, and a two-way straight-through and controllable throttling device, which connects the first working space to the second working space in the open state, is arranged in the piston.
