An electronically controller external damper reservoir assembly (eRESI) can be connected to a passive damper and/or substituted for an existing external reservoir to provide semi-active damping control. The eRESI includes a reservoir and a variable base valve assembly actuated by an actuator. A controller is in communication with the actuator and a sensor providing input signal indicative of vehicle movement and is programmed to generate a damping control signal to the actuator based on the input signal, to dynamically control the damping force outputted by a passive damper hydraulically connected to the eRESI. A P/T sensor can be installed to a gas chamber of a vehicle damper to generate a P/T signal indicative of the pressure and temperature of the gas. The controller is programmed to determine a damper position of the damper based on the P/T signal.

This invention pertains to shock absorbers, and a method of controlling their operation. Specifically, this invention relates to use of a user interface allowing to control the sensitivity of various parameters used by a programmed electronic control unit. When in operation, said electronic control unit automatically send calculated and user-adjusted electronic signals to electronic control devices which proportionally regulate flow of fluid within each shock absorbers of a vehicle.

A method and system for estimating surface roughness of a ground for an off-road vehicle to control steering of a vehicle, an implement, or both, comprises detecting motion data of an off-road vehicle traversing a field or work site during a sampling interval. A first sensor is adapted to detect pitch data of the off-road vehicle for the sampling interval to obtain a pitch acceleration. A second sensor is adapted to detect roll data of the off-road vehicle for the sampling interval to obtain a roll acceleration. An electronic data processor or surface roughness index module determines or estimates a surface roughness index based on the detected motion data, pitch data and roll data for the sampling interval. The surface roughness index can be displayed on the graphical display to a user or operator of the vehicle.

The present disclosure relates to autonomous driving vehicles and methods for adjusting a sensor of the vehicles. A sensing assembly includes a housing having a base, the housing being affixed to a vehicle through the base; and a sensor disposed in the housing and configured to sense information of the vehicle. The sensor is rotated with respect to the vehicle in response to a motion of the vehicle.

A method of producing an anti-roll moment distribution module for a vehicle comprises determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting understeer characteristics of the vehicle based on the maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates based on (i) the maximum lateral acceleration and (ii) the reference understeer characteristics using a non-linear quasi static vehicle model, storing the plurality of reference yaw rates in a first look up table in the anti-roll moment distribution module, determining a plurality of feedforward contributions using the non-linear quasi static model of the vehicle. Each feedforward contribution of the plurality of feedforward contributions can be used to determine a front to total anti-roll moment distribution for the vehicle. The plurality of feedforward contributions are stored in a second look up table in the anti-roll moment distribution module.
