A system and method for determining a roadway bank angle based on vehicle information. The method may include the steps of: obtaining vehicle information from at least one vehicle, the vehicle information is obtained from at least one of a global navigational satellite system (GNSS) receiver and one or more onboard vehicle sensors, and the GNSS receiver and the one or more onboard vehicle sensors are installed in the at least one vehicle; performing a roadway bank angle determination process using the obtained vehicle information to obtain a roadway bank angle; and updating a representative roadway bank angle based on the roadway bank angle.

A system is provided for evaluating vehicle performance. The system includes a function system model that models an operation of a function system of a vehicle and an operation of which is determined based on a control signal output from a controller within the vehicle. Additionally, the system includes a dynamic model configured to model a behavior of the vehicle based on the operation of the function system model.

A device for controlling wheel slip of a vehicle includes: a displacement sensor for measuring a suspension displacement of drive wheels; and a controller configured to control braking of the drive wheels in consideration of the suspension displacement of the drive wheels when slip occurs on the drive wheels. The device may control braking of a slip-occurred wheel in consideration of a displacement of a suspension corresponding to the slip-occurred wheel of the vehicle.

A parking assist system includes: a control device configured to execute a driving process for autonomously moving a vehicle to a target position; a steering operation member configured to receive a steering operation performed by an occupant; a vehicle state detecting device; and a notification device configured to make a notification to the occupant. In the driving process, the control device executes vehicle speed control and steering control. When, during execution of the driving process, the control device determines that the vehicle is a suspension state in which the driving process should be temporarily suspended, the control device causes the notification device to output a prescribed notification and executes a suspension process. In the suspension process, the control device executes the vehicle speed control to stop the vehicle and stops the steering control.

A system for dynamically managing individual suspension settings for a vehicle based on a determined suspension mode is provided. Based on the user input and obtained sensor input, the system can then determine a suspension mode for a plurality of individually controllable components by specifying values or commands for each controllable component. A first mode may correspond to a lowering of the plurality of controllable. A second mode may correspond to lowering two controllable components corresponding to the rear wheels of the vehicle and raising two controllable components corresponding to front wheels of the vehicle. A third mode may correspond to a lowering of the plurality of controllable components to effectively drop the height of the vehicle to a threshold point. The system may further implement various validation processes that can validate the determined suspension mode and make further adjustment to individual controllable portions based on load or ground measurements.

Data is received from a vehicle in a stationary support structure. One or more physical attributes of an infrastructure element is determined based on the vehicle data.

A non-transitory computer readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to receive road quality data from at least one vehicle in a fleet of vehicles and determine a route for the at least one vehicle in the fleet of vehicles. The road quality data may be gathered by at least one sensor configured to detect autonomous vehicle movements and orientation. The route may avoid a segment of road that is associated with poor road quality data.

A method of controlling driving force of a vehicle, includes providing a first filter for removing or reducing a natural frequency component of the vehicle suspension pitch motion, and a second filter for extracting or increasing the natural frequency component of the vehicle suspension pitch motion to a controller of the vehicle, determining a required driving force command based on vehicle driving information collected during driving of the vehicle, determining a driving force command after filter application through a processing process by the first filter taking the determined required driving force command as input thereof, determining a driving force correction amount through a processing process by the second filter taking feedback driving force as input thereof, and correcting the driving force command after filter application using the driving force correction amount and controlling driving force applied to a driving wheel of the vehicle by a driving device of the vehicle using the driving force command after the correction.

The invention i.a. relates to a load transfer arrangement (10) for a vehicle (12) including a chassis (14) with at least one braked axle (16), the arrangement (10) comprising: a non-driven load axle (18), and an air suspension assembly (20) including at least one air cushion (22) arranged between the chassis (14) and the non-driven load axle (18) in order to transfer load from the braked axle(s) (16) to the non-driven load axle (18), wherein the non-driven load axle (18) is unbraked, and wherein the arrangement (10) further comprises: an evacuation controller (24) configured to provide a pressure release trigger in response to a current or predicted braking event of the vehicle (12), and at least one evacuation valve (26) configured to, in response to receiving the pressure release trigger, evacuate pressure from the at least one air cushion (22) in order to remove load from the non-driven load axle (18) and increase load on the braked axle(s) (16).

A steering control system for a vehicle that considers the limitations of at least one of the vehicle and the environment is contemplated. The steering control system can receive a vehicle characteristic, an environmental condition, a desired amount of turning, and a desired velocity of the vehicle. Based on some, or all of these parameters, the steering control system can determine at least one of a wheel torque, a wheel angle, a wheel camber, and a wheel suspension for a desired vehicle path to enhance vehicle performance.
