Realized is a technique of highly accurately calculating a state quantity of a vehicle. An ECU (600) of a vehicle (900) includes a ground contact load calculating section (610), an input quantity calculating section (620), a first state quantity calculating section (630), an observable calculating section (640), a second state quantity calculating section (650), and a damper ECU (660). The ECU (600) calculates a first state quantity of the vehicle (900) by inputting, into a vehicle model, a value calculated from a G sensor value and/or the like, and calculates a second state quantity of the vehicle (900) by correcting the first state quantity with use of an observable which is calculated from a ground contact load and a spring constant gain of a tire.

The technology relates to determining whether a vehicle operating in an autonomous driving mode is experiencing an anomalous condition, for instance due to a loss of tire pressure, a mechanical failure, or a shift or loss of cargo. The actual current pose of the vehicle is compared to an expected pose of the vehicle, where the expected pose is based on a model of the vehicle. If a pose discrepancy is identified, the anomalous condition is determined from information associated with the pose discrepancy. The vehicle is then able to take corrective action based on the nature of the anomalous condition. The corrective action may include making a real-time driving change, modifying a planned route, alerting a remote operations center, or communicating with one or more other vehicles.

A commercial vehicle with a cargo space includes a detection unit for detecting movement of a wheel suspension and/or an inertial measuring unit for detecting movements of a sprung mass of the vehicle in order to evaluate a loading state of cargo in the cargo space. To provide improved cargo capacity, improved user-friendliness, and improved driving behavior, the commercial vehicle has an optical signaling unit arranged in the cargo space which is electrically activatable using an evaluation electronics unit, wherein the evaluation electronics unit is configured to activate the signaling unit on the basis of signals of the detection unit and/or the inertial measuring unit which are generated upon placement of the cargo on a cargo surface of the cargo space in such a way that an optimum position of the cargo surface is displayable by means of the signaling unit.

In a method of creating a database for preview vibration damping control, road surface displacement-associated information detected by a detection device is acquired, positional information capable of identifying a position where the road surface displacement-associated information is detected is acquired, a road surface displacement-associated value associated with a vertical displacement of a road surface is calculated based on the road surface displacement-associated information, and a set of data obtained by linking the road surface displacement-associated value and the positional information with each other is stored into a storage device as part of a database. When it is determined that the magnitude of the road surface displacement-associated value exceeds a permissible reference value set in advance, the magnitude of the road surface displacement-associated value is corrected in a reducing manner, prior to the step of storing the set of data into the storage device.

A method for controlling driving force of a vehicle includes determining a natural frequency of vehicle suspension pitch motion according to characteristics of a suspension device of the vehicle, providing a filter configured for removing or passing a natural frequency component of the vehicle suspension pitch motion to a control unit of the vehicle, determining, by the control unit, a required driving force command based on vehicle driving information collected during vehicle driving, determining, by the control unit, a final front wheel driving force command and a final rear wheel driving force command through a filtering process using the filter from the determined required driving force command, and controlling, by the control unit, a driving force applied to a front wheel and a rear wheel of the vehicle by a driving device for driving the vehicle according to the determined final front wheel driving force command and the determined final rear wheel driving force command.

Provided is a travel evaluation method of making an evaluation related to travel of a vehicle capable of traveling in a leaning position, the method including: obtaining a tire force which is an external force exerted on a wheel of the vehicle from a ground surface; and deriving an evaluation index related to travel of the vehicle. The evaluation index includes a positive evaluation index as a rating of a positive evaluation related to travel of the vehicle. In deriving the evaluation index, the positive evaluation index is set higher as the tire force increases, and the evaluation index is corrected based on an influential parameter other than the tire force.

A tipping avoidance system configured to modify operation of a collision avoidance system. The tipping avoidance system may include a payload determination system configured to generate a payload signal, and a load position determination system configured to generate a load position signal. The tipping avoidance system may also include a tipping avoidance controller configured to receive the payload signal and the load position signal, and determine, based at least in part on the payload signal and the load position signal, a minimum stopping distance at or above which the machine will not tip due at least in part to deceleration of the machine from a travel speed to a stopped condition. The tipping avoidance controller may be configured to communicate with a braking controller, such that the braking controller adjusts a stop triggering distance based at least in part on the minimum stopping distance.

A representation of a first set of weights associated with a vehicle prior to a drive are received, the vehicle including a plurality of axles, a plurality of wheels attached to the plurality of axles, and a load. A warning is caused to be output in response to at least one weight from the first set of weights being outside a predetermined range. Longitudinal and lateral dynamics associated with the vehicle during the drive are determined. A second set of weights associated with at least one axle from the plurality of axles during the drive are determined. A determination is made if at least one remedial action should be performed based on the longitudinal dynamics, the lateral dynamics, and the second set of weights. In response to determining that the at least one remedial action should be performed, the at least one remedial action is caused to be performed.
