A method is provided to control a power steering device and an adaptive damping system of a motor vehicle. The power steering device makes available a mechanical steering angle range that is limited by steering stops. The adaptive damping system makes available a variable damping force. The damping force of the adaptive damping system is increased and a maximum achievable steering angle is simultaneously increased in case a steering stop is reached.

A method of controlling the stability of a vehicle. The method comprises acquiring an actual value of a vehicle stability parameter and determining a difference between the actual parameter value and a target value of that stability parameter. The method further comprises applying a damper intervention threshold to the difference between the actual and target parameter values, the damper intervention threshold representing a magnitude of the difference between the actual and target parameter values at which damper intervention may be utilized to mitigate a potential over-steer or under-steer condition. The method still further comprises predicting the occurrence of an over-steer or under-steer condition when the damper intervention threshold is exceeded.

A drive mode hierarchy includes drive mode categories and drive modes belonging to each category. Each drive mode defines values for attributes of the drivetrain and/or suspension of a vehicle. Each drive mode may further have towing and non-towing sub-modes with the towing sub-mode being used when a trailer is detected. An interface is provided for selecting drive modes from the hierarchy and modifying the attributes. The vehicle may define a plurality of trailer profiles including attributes of trailers, such as weight and aerodynamic drag. A user may select among trailer profiles and define the attributes of the trailer profiles. Interfaces displayed by the vehicle may vary according to the selected drive mode and may include a chassis view with interface elements displaying real-time information of components of the vehicle, such as wheels, suspension, and battery. Tiles including real-time information may be displayed according to the selected drive mode.

The invention provides a vehicle control method and device, a computer storage medium, and a vehicle, which are applied to the technical field of automobiles. The vehicle control method includes: determining, based on first information, second information, and third information, whether a vehicle is performing a reverse parking maneuver; comparing a reversing speed with a predetermined first speed when the vehicle is performing the reverse parking maneuver; and if the reversing speed is higher than the predetermined first speed, outputting a first control signal to adjust the reversing speed such that the reversing speed is not higher than the predetermined first speed, where the first information includes information indicating that the vehicle is in reverse gear, the second information indicates an environment surrounding the vehicle, and the third information indicates that the reversing speed is lower than a predetermined second speed, where the predetermined first speed is lower than the predetermined second speed.

A vehicle control system includes a plurality of sensors that determine ride height information of a vehicle, a sensor that determines pitch information for the vehicle, and a controller that selectively applies traction torque and braking torque to wheels of the vehicle based on vehicle speed, the pitch information and the ride height information.

A system and a method for estimating the International Roughness Index (IRI) of a road or road segment includes determining the IRI as a function of physical quantities relating to the motion of a vehicle, for instance the vertical accelerations, and to the vehicle itself, for instance the damping and stiffness coefficients of the suspensions of the vehicle and the tires mounted on the vehicle.

A method and system are provided for identifying time-varying suspension characteristics of heavy-load vehicles. The method includes collecting sequential control state data of a mining truck using sensors, predicting parameter-related factors through a deep learning network, estimating suspension stiffness and damping coefficients via a linear dynamic model considering longitudinal-vertical coupling, and predicting future system states through a nonlinear dynamic model based on the estimated parameters and learned factors. According to the method, a deep learning network is integrated into a physical model of the mining truck, an accurate longitudinal-vertical dynamical model of the mining truck is established, accurate suspension parameters are identified, the stiffness damping time-varying characteristics of the suspension of the mining truck are given through a physical model-data driving method, and the model has certain interpretability and generalization; the rigidity and damping of the four suspensions can be obtained only through sprung information.

A method of operating a tow vehicle and a trailer to prevent trailer sway. The method includes detecting a predetermined maneuver for the tow vehicle and the trailer based on operating parameters. The predetermined maneuver corresponds to a subset of operating parameters from the plurality of operating parameters. A critical speed is determined based on the subset of operating parameters. The critical speed corresponds to a speed of the tow vehicle and trailer where a damping between the tow vehicle and the trailer cannot prevent trailer sway. A vehicle control is adjusted for the tow vehicle based on the critical speed.

In a vehicle control system S and a vehicle control device 100, when both a deceleration operation unit 52 and a starting operation unit 54 are operated while a vehicle 1 is stopped, a control unit 166 performs change control processing before the vehicle 1 starts, the change control processing changing one of a damping force of suspensions 30 and 40 and a vehicle height in a case where the one is controlled and changing both of the damping force of the suspensions 30 and 40 and the vehicle height in a case where the both elements are controlled.
