Vehicle center of gravity (CoG) height and mass estimation techniques utilize a light detection and ranging (LIDAR) sensor configured to emit light pulses and capture reflected light pulses that collectively form LIDAR point cloud data and a controller configured to estimate the CoG height and the mass of the vehicle during a steady-state operating condition of the vehicle by processing the LIDAR point cloud data to identify a ground plane, identifying a height difference between (i) a nominal distance from the LIDAR sensor to the ground plane and (ii) an estimated distance from the LIDAR sensor to the ground plane using the processed LIDAR point cloud data, estimating the vehicle CoG height as a difference between (i) a nominal vehicle CoG height and the height difference, and estimating the vehicle mass based on one of (i) vehicle CoG metrics and (ii) dampening metrics of a suspension of the vehicle.

An apparatus and a method for controlling motion of a vehicle to improve turning motion performance are provided. The processor determines a riding position of a user, receives information about a steering angle of the vehicle, and outputs a vehicle control signal with regard to turning motion performance according to at least one of a phase difference between a yaw rate and lateral acceleration or a lateral slip angle with respect to the riding position, based on the received steering angle. A controller controls the vehicle in accordance with the vehicle control signal. The apparatus provides a passenger of the vehicle with optimal turning motion performance.

A machine is disclosed. The machine may include a control system that includes a controller configured to: determine a center of gravity of the machine based on a state of the machine; determine at least one of a slope limit or a pitch limit for the machine based on the center of gravity; receive a command to perform an operation that, if performed, would affect at least one of a slope or a pitch of the machine; determine whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit; and selectively perform the operation based on determining whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit.

A method includes identifying sensor data associated with corresponding distal ends of one or more axles of an autonomous vehicle (AV). The method further includes determining, based on the sensor data, mass distribution data of the AV. The mass distribution data is associated with a first load proximate a first distal end of a first axle of the AV and a second load proximate a second distal end of the first axle of the AV. The method further includes causing, based on the mass distribution data, performance of a corrective action associated with the AV.

An embodiment device for controlling autonomous driving includes a roll angle estimated value calculation device configured to calculate a roll angle estimated value of a vehicle based on a height of a center of gravity of the vehicle, a sprung mass, a spring constant of a suspension, a target speed, and a target turning radius, and a controller configured to compare a roll angle of the vehicle with a preset reference roll angle to adjust the target speed or the target turning radius of the vehicle.

A slope estimation device estimates a slope of a vehicle traveling road, and includes an input section that acquires a detected value of an acceleration sensor for detecting acceleration in a front-back direction of the vehicle, a centripetal force detecting section that detects centripetal force acting on the acceleration sensor due to a turning motion of the vehicle, and a slope computing section that computes the slope of the vehicle traveling road based on the detected value of the acceleration sensor. When the vehicle is in the turning motion, the slope computing section computes the slope of the traveling road by determining a component of the centripetal force superimposed on the detected value of the acceleration sensor based on a turning center position of the vehicle, a gravity center position of the vehicle, and an installation position of acceleration sensor, and subtracting the component of the centripetal force from the detected value of the acceleration sensor.

Disclosed is a method for determining a position of a motor vehicle by means of a location device of the motor vehicle. First, a first position (x.sub.1) related to an installation point of the location device in the motor vehicle is determined. In order to determine a position suitable for controlling the motor vehicle, with reference to the said first position (x.sub.1) a second position (x.sub.2) related to a center of gravity of the vehicle is determined, in that the first position (x.sub.1) is offset by a distance (a) between the said installation point of the location device and the center of gravity of the vehicle.

A manager is installed in a vehicle. The manager includes: an accepting unit that accepts, from a plurality of advanced driver assistance system applications, a plurality of kinematic plans including first information that is information representing lateral-direction motion of the vehicle; an arbitration unit that performs arbitration of the kinematic plans; a first output unit that distributes a motion request based on a result of arbitration performed by the arbitration unit to at least one of a plurality of actuator systems; and a second output unit that outputs second information used for generating the first information to at least one of the ADAS applications.

A system for preventing rolling-over of vehicles is disclosed: The system may include: at least one camera attached to a portion of the vehicle such that images capture by the camera include a portion of the vehicle and a portion of a surrounding area; a communication module; and a controller configured to: receive from the camera, via the communication module, at least one image; receive data related to the parameters of the vehicle; calculate a relative position between the vehicle and a ground based on the received at least one image; calculate a location of the vehicle's center of gravity based on the received at least one image and the data related to the parameters of the vehicle; and determine a probability of rolling-over the vehicle based on the calculated center of gravity and the relative position.

A lane departure prevention device includes a control unit that executes lane keeping control (automatic steering of a steering wheel and/or issuing of a warning) when it is determined that a vehicle may move out of a lane. The control unit withholds execution of the lane keeping control until it is determined that a return-to-control condition is satisfied when it is determined that a driver has gone from showing no intention to move out of the lane to showing an intention to move out of the lane to cross a first lane boundary. The control unit continues, when it is determined that the vehicle is approaching a second white line present in a traveling direction with a speed equal to or faster than a reference value, continues withholding the execution of the lane keeping control even when it is determined that the return-to-control condition is satisfied.
