The ECU of the stabilizer control apparatus determines, based on a high frequency component of a wheel acceleration and a low frequency component of a wheel speed difference, whether a road surface state is a rough road state or a smooth road state. When the road surface state is determined to be the rough road state, the ECU sets a turning determination threshold to a rough road threshold. When the road surface state is determined to be the smooth road state, the ECU sets the threshold to a smooth road threshold. When a turning determination parameter is greater than the threshold, the ECU sets each of first, second, and third cylinders to a lock state to increase rigidity of stabilizers. When the turning determination parameter is smaller than the turning determination threshold, the ECU sets each of the cylinders to a free state to decrease the rigidity of the stabilizers.

Embodiments of the present invention provide a control system (100) for determining a suspension calibration of a vehicle (800). The control system (100) has one or more controllers (120) that receive route data indicative of a route ahead of the vehicle (800). One or more processors (130) determine, from the route data, a prediction of a first acceleration at a first location (320) ahead of the vehicle (800) and a second acceleration at a second location (330) ahead of the first location(320). The one or more processors (130) determine a suspension calibration of the vehicle (800) in dependence on the second acceleration. The actual acceleration of the vehicle (800) is measured at the first location (320) and compared with the first acceleration. If the measured and first acceleration are within a predetermined tolerance, the processor (120) produces a suspension control signal at output (121) which is received by a suspension controller (140) to apply the suspension calibration prior to the vehicle (800) arriving at the second location (330).

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

The cloud includes a server and a storage device. The storage device includes a road surface information map. When a first sampling distance is equal to or longer than a first distance threshold, the server performs re-sampling to interpolate data in such a manner that sampling positions located at a second sampling distance and unsprung mass member displacements of the respective sampling positions exist so as to produce re-sampled data-for-producing-map. The server stores a sub-sectional unsprung mass displacement in a storage area corresponding to a sub-section of the road surface information map, based on the re-sampled data-for-producing-map.

To obtain a controller capable of controlling a regular circular turning characteristic of a vehicle during turning. A controller according to the present invention is a controller that is mounted to a vehicle including a shock absorber of a damping force adjustment type provided between a vehicle body and a wheel and outputs a command signal corresponding to a damping force of the shock absorber to an actuator that adjusts the damping force of the shock absorber. The controller is configured to output the command signal to the actuator to adjust the damping force of the shock absorber and control a regular circular turning characteristic of the vehicle when the vehicle is brought into a stable turning state where the vehicle turns in a state where a degree of a change in a physical quantity associated with a travel posture is smaller than that in a reference state.
