Systems, methods, and computer readable storage media provide dynamic chassis and tire status indications associated with a vehicle. Lift axle status data may be graphically represented by a lift axle indicator dynamically provided in a shared notification/messaging space positioned within the driver's line of sight during a lift axle transition. The lift axle indicator may include a side-view representation of the vehicle including a plurality of axle sections indicating the status of each axle. The lift axle indicator may be suppressed when air pressure is stabilized. Additionally, a graphical representation of data associated with statuses (e.g., air pressure, temperature) of each tire may be provided in a top-down view representation of the vehicle including its associated tire/axle configuration and the tire pressure for each tire. The graphical representation may be configured to reflect the correct number of axles and tires per position, and may further include a tractor versus trailer designation.

A method, system and non-transitory computer readable medium for multi-stage communication between an autonomous vehicle and a road user. The autonomous vehicle uses vehicle external cameras, a LiDAR sensors and radar sensors to image the surrounding environment. Image processing circuitry is used to develop a view of the surrounding environment from the sensed images and the view is combined with stored map data. Road users, which may include pedestrians, bicyclists, motorcyclists and non-autonomous vehicles are identified on the view and it is determined whether the movement of the road user will intersect the trajectory of the autonomous vehicle. The autonomous vehicle performs a vehicle behavior modification as a first stage signal to alert the road user of its intent. If the road user does not react to the first stage signal, the autonomous vehicle activates additional external lighting as a second stage signal to alert the road user.

A method for checking status of a vibration damper of a motor vehicle includes selecting a suitable section of a roadway, via processing circuitry at a server, based on section selection criteria comprising a number of passing vehicles, a data input sufficient for correlation analyses of the vibration damper, and homogeneity of the roadway. The method further includes acquiring data from a plurality of other vehicles while the other vehicles are driving through the section, grouping data items from the acquired data that are specifically associated with vibration damper status, classifying the status of the vibration damper based on the data items, and informing the driver about the status of the vibration damper. The data on the number of the other vehicles may include data indicative of other vehicle vibration dampers in new condition defining reference values for a degree of wear of the vibration damper.

A method for avoiding a vehicle undercarriage collision includes identifying an object within a field of view of a vehicle with at least one sensor. a size of the object is determined by comparing the size of the object to a predetermined height of the undercarriage of the vehicle. An indication is provided if the object will collide with an undercarriage of the vehicle

The present invention relates to a method for determining a desired speed of a vehicle (1), preferably an autonomous vehicle. The vehicle comprises a shock absorber arrangement (2), preferably an hydraulic shock absorber arrangement, having an elastic hysteresis. The method comprises—obtaining (501) a reference value indicative of the energy dissipated by the shock absorber arrangement (2) in a reference driving condition of a vehicle and—determining (502) a speed of the vehicle for which the value indicative of the energy dissipated by the shock absorber arrangement (2) in a similar driving condition is expected to fall within a predetermined energy dissipation range, using said reference value.

A vehicle height adjusting device includes a vehicle height adjusting unit, a prediction unit, and a vehicle height control unit. The vehicle height adjusting unit adjusts a vehicle height to one of a first state and a second state. In the first state, the vehicle height is set to a predetermined height, and in the second state, the vehicle height is set lower than the first state. The prediction unit predicts whether a drive battery (lower portion) of a vehicle interferes with a road surface in the second state. The vehicle height control unit controls the vehicle height adjusting unit to set the vehicle height to one of the first state and the second state. When the prediction unit predicts an interference between the drive battery of the vehicle and the road surface, the vehicle height adjusting unit restricts a transition from the first state to the second state.

The present invention relates to a method for determining a functional status of a vehicle shock absorber arrangement (100). The method determines a difference between force values during compression and expansion of the vehicle shock absorber arrangement (100), whereby the shock absorber arrangement (100) can be determined to be degraded if the difference is below a predetermined threshold.

The axle comprises a hydraulic circuit (15) interconnecting the chambers (92, 112) of the left (9) and right (11) jacks, in which a fluid is present at a given pressure, making it possible to press the rods (90, 110) of the left jack (9) and of the right jack (11) against the bridge (5), and at least one solenoid valve (150, 152) on a branch (15A) of the hydraulic circuit (15) connected to the chamber (94) of the left jack (9), and at least one solenoid valve (154, 156) on a branch (15B) of the hydraulic circuit (15) connected to the chamber (114) of the right jack (11), wherein each of these solenoid valves (150, 152, 154, 156) may be positioned in an open position, in which fluid may flow freely, and a closed position, in which the fluid is trapped in the chamber (94, 114) of the corresponding jack (9, 11). Each of the chambers (94, 114) of the left jack (9) and of the right jack (11) has a pressure sensor (23, 25) designed to measure the pressure of the fluid in each of the chambers (94, 114).
