  • Patent number: 9493182
    Abstract: Disclosed are a system and a method for compensating friction due to rack bending in a motor driven power steering system. The system for compensating friction may include a rack bending signal processor and a friction compensation controller. The rack bending signal processor may determine whether a rack bar bends when a lateral force is transmitted to the rack bar in turn of a vehicle. The friction compensation controller may calculates a friction compensation torque by adding a counter-rack bending torque according to a bending displacement of the rack bar to a basic steering torque of a motor and control a current supplied to the motor to apply the friction compensation torque if it is determined that the rack bar bends.

  • Patent number: 9493176
    Abstract: A method operates a railway safety system having at least one trackside device while taking into account a measured velocity value recorded when the rail vehicle drives into a switch-on section of the railway safety system. In order to minimize the closing times for a level crossing by such a method, the measured velocity value is used as the basis for checking whether a correction time for forwarding a signal from the one trackside device to an associated railway safety assembly is to be set according to the measured velocity value when the rail vehicle drives into the switch-on section. Thereafter, a set correction time is checked to determine if the set correction time should remain effective according to at least one further influencing variable of the rail vehicle that determines the travel time. A railway safety system for carrying out the method is also provided.

  • Patent number: 9488483
    Abstract: One or more embodiments of techniques or systems for creating a road marking classification template and vehicle localization using road markings are provided herein. A road marking classification template database includes templates of training images taken from different navigation environments. A training image with a road marking can be rectified and enhanced. Corners can be calculated for the road marking using the rectified or enhanced image. Locations can be determined for the corners and stored as part of a template. Similarly, a runtime image can also be rectified, enhanced, boosted, etc. Additionally, corners can be calculated for the runtime image and matched against corners of templates from the template database. A location or a pose of a vehicle can be determined using the match. In this way, vehicle localization is provided such that drift or other issues associated with GPS, such as occlusion, are mitigated, for example.

  • Patent number: 9464406
    Abstract: A construction machine has a work implement and a work implement operating device. The work implement has a boom, arm, and bucket. A limit velocity determining unit determines a limit velocity of the boom from the limit velocity of the entire work implement, the arm target velocity, and the bucket target velocity. The distance when the blade tip of the bucket is positioned outside of the design plane is a positive value and the velocity in a direction from inside of the design plane toward outside of the design plane is a positive value. The first limit condition includes a condition that the limit velocity of the boom is greater than the boom target velocity. When the first limit condition is satisfied, a work implement control unit controls the boom to match the limit velocity of the boom and controls the arm to match the arm target velocity.

  • Patent number: 9460627
    Abstract: A collision determination device is mounted to an own vehicle and determines a probability of a collision with a moving object. The collision determination device determines whether or not an own vehicle will collide with a moving object that is detected within a captured image. The collision determination device determines whether or not the moving object is in a shielded state where at least a portion of the moving object is hidden behind another object or the moving object appears from behind another object. The collision determination device sets an amount of time required for the collision determining means to complete a determination related to the collision to a shorter amount of time when the moving object is in the shielded state, compared to when the moving object is not in the shielded state.
