The present invention relates to a method for controlling the position of a vehicle to ensure stable position of a vehicle against tilting due to a rapid change in vehicle speed. The method includes: determining whether a vehicle speed is rapidly changing in a straight direction on the basis of an extent of depression of a pedal that changes a position of a steering wheel and a change in vehicle speed; determining whether the vehicle is tilting on the basis of a change in a yaw-rate by means of the controller when the vehicle speed is rapidly changing in the straight direction; and providing compensation torque in the direction opposite the direction in which the vehicle is tilted by operating a steering motor when the controller determines that the vehicle is tilting.

An ECU controls an in/out motor so as to, interlockingly with turning of a vehicle, change a viewing range of a periphery of the vehicle with respect to a vehicle occupant. The ECU controls the in/out motor such that the viewing range returns to an original viewing range by a time of an end of turning.

Example embodiments relate to identification of proxy calibration targets for a fleet of sensors. An example method includes collecting, using a sensor coupled to a vehicle, data about one or more objects within an environment of the vehicle. The sensor has been calibrated using a ground-truth calibration target. The method also includes identifying, based on the collected data, at least one candidate object, from among the one or more objects, to be used as a proxy calibration target for other sensors coupled to vehicles within a fleet of vehicles. Further, the method includes providing, by the vehicle, data about the candidate object for use by one or more vehicles within the fleet of vehicles.

A vehicle steering system for a compact mobile elevating work platform (“MEWP”) or other vehicle and a method for dynamically determining independent wheel steering angles such that a predetermined steering geometry between steerable wheels of the vehicle are described. The steering system determines coordination of the independent wheels based on angle differences of the steerable wheels. The independent master and follower wheels of the present system are not mechanically linked, and the absence of mechanical linkages between the independent steerable wheels allows for efficiency of spatial efficiency and steering geometry accuracy. The independent operation facilitates accommodation of the steering actuators into confined lateral compartments, which itself enables the machine lifting mechanism to occupy a space hitherto used for a mechanical steering connection between the wheel assemblies.

A method of maintaining stability of a motor vehicle having a first axle, a second axle, and a steering actuator configured to steer the first axle includes determining localization and heading of the vehicle. The method also includes determining a current side-slip angle of the second axle and setting a maximum side-slip angle of the second axle using the friction coefficient at the vehicle and road surface interface. The method additionally includes predicting when the maximum side-slip angle would be exceeded using the localization, heading, and determined current side-slip angle as inputs to a linear computational model. The method also includes updating the model using the prediction of when the maximum side-slip angle would be exceeded to determine impending instability of the vehicle. Furthermore, the method includes correcting for the impending instability using the updated model and the maximum side-slip angle via modifying a steering angle of the first axle.
