  • Patent number: 9285485
    Abstract: A method is provided for estimating vehicle velocity for a vehicle using a single-antenna global positioning system (GPS). An absolute speed and a course angle of the vehicle is measured using the single-antenna GPS. The yaw rates of the vehicle are measured independently of the GPS. An integrated yaw rate of the vehicle is calculated as a function of the measured yaw rates over a period of time. A yaw angle is determined as a function of a reference yaw angle and the integrated yaw rate. Aside slip angle is calculated as a function of the estimated yaw angle and the course angle provided by the GPS. The vehicle velocity is determined as a function of the absolute speed and the side slip angle. The vehicle velocity is provided to a vehicle dynamic control application.

  • Patent number: 9260089
    Abstract: The invention relates to a method for controlling a deceleration arrangement (10) of a motor vehicle with at least one regenerative braking device (12) which is designed to decelerate the motor vehicle by means of a variable braking torque and to generate electrical energy corresponding to the braking torque. A return speed of an operating element for driving the motor vehicle, in particular an accelerator pedal (22), is detected (S2). A predefined braking torque is exerted (S5) by the regenerative braking device (12) if the return speed and/or a variable correlating thereto exceed(s) or fall(s) below a predefined threshold value.

  • Patent number: 9239580
    Abstract: To improve the accuracy of the self position estimation of a mobile robot. A robot measures a distance to an object in the mobile environment by using a range sensor. An environmental map storage unit stores an environmental map containing a plurality of map data each corresponding to a respective one of a plurality of measurement directions from which a point in the mobile environment is to be observed. A self position estimation unit selects a map data corresponding to a measurement direction in which a distance to the object is measured by the range sensor from the plurality of map data. Then, the self position estimation unit estimates a self position of the mobile robot based on the selected map data and range data obtained by the range sensor.

  • Patent number: 9216745
    Abstract: A method for providing shared control over movement of a vehicle within a space. The method includes receiving user input related to a velocity and a direction for the vehicle within the space. The method includes processing the user input to selectively adjust the velocity and the direction desired by the user based on a set of predefined constraints to generate a trajectory for the vehicle for an upcoming time period. The method includes operating drive mechanisms in the vehicle based on the trajectory to move the vehicle from a first position to a second position within the space during the upcoming time period. A grid map defining locations of obstacles in the space may be used to define the trajectory to avoid collisions, and a guidance trajectory may be used to further control movement to achieve a desired throughput and control vehicle movement within particular portions of the space.

  • Patent number: 9134734
    Abstract: A range-measuring sensor is arranged on a vehicle. The direction of measurement or plane of measurement of the sensor can be altered by driving a sensor motor. A map of the environment is produced by using natural landmarks. A predetermined route along which the vehicle is intended to move is stipulated. Landmarks which can serve as a localization aid along the predetermined route are determined. The environment is scanned at different times by using the sensor in order to detect the previously determined landmarks while the vehicle is moving along the predetermined route. The vehicle is localized by comparing the detected landmarks with the landmarks recorded on the map. The sensor motor is actively controlled, at least in areas of the environment with only a few previously determined landmarks, such that the sensor is oriented to these landmarks in order to ensure that they are detected.

  • Patent number: 9114810
    Abstract: A preceding vehicle selection apparatus detects an object ahead of the own vehicle, and determines a relative position and a relative speed in relation to the own vehicle for each object ahead. Based on detection results of the object ahead, a lateral movement speed of the object ahead is determined. Based on the calculated lateral movement speed, the lateral position of the object ahead with reference to a traveling direction of the own vehicle is corrected. Based on the relative position of the object ahead of which the lateral position has been corrected, an own vehicle lane probability for each object ahead is calculated. Based on the calculated probability, a preceding vehicle from the objects ahead is selected. Based on a distance to the object ahead, the lateral position of the object ahead is corrected such that an amount of correction in the lateral position decreases as the distance increases.

  • Patent number: 9086738
    Abstract: An optical tracking device that is capable of operation on both glossy and diffuse surfaces includes at least one housing, at least one light source, and at least one sensor. The light source emits light toward a surface on which the housing is moved and the sensor receives the light emitted by the light source after it is reflected off of the surface. The light source is oriented such that the angle of incidence of the emitted light corresponds to Brewster's angle. The sensor may be also oriented such that the angle of reflection of the reflected light corresponds to Brewster's angle. The light emitted by the light source may be polarized to increase the p-polarization of the emitted light and/or the light received by the sensor may be filtered to block s-polarized portions of the reflected light.
