Patent number: 10207713Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for performing vehicle traction control. Time intervals between points of rotation of a rotating vehicle output shaft are measured. Indicators of shaft rotation rate are generated using, for each generated indicator, a set of one or more of the time intervals. The generated indicators of shaft rotation rate are used to determine a value indicative of a rate of change of shaft rotation rate. An indicator of a maximum allowable output shaft rotation rate is computed. A current indicator of output shaft rotation rate is determined to exceed the maximum allowable output shaft rotation rate. In response to determining that the current indicator exceeds the maximum allowable output shaft rotation rate, a signal to trigger application of a traction control mechanism is output.Type: GrantFiled: December 5, 2016Date of Patent: February 19, 2019Assignee: Davis Intellectual Properties LLCInventor: Shannon R.

Patent number: 10202124Abstract: A determination unit in an ECU of a rough terrain vehicle determines a reverse running state in a case that an engine rotational speed of an engine decreases when a traveling drive force is generated in the rough terrain vehicle. Further, if the determination unit determines occurrence of the reverse running state, the ECU refers to a clutch hydraulic pressure map, and sets a target hydraulic pressure so as to decrease gradually over time.Type: GrantFiled: March 30, 2017Date of Patent: February 12, 2019Assignee: HONDA MOTOR CO., LTD.Inventor: Naoki Sakamoto

Patent number: 10196047Abstract: Methods and apparatus are disclosed for contamination prevention of vehicle cameras and sensors. An example vehicle includes an exterior, a camera along the exterior and including a lens, and a controller. The controller is to determine, based upon images captured by the camera, whether a contaminant is approaching the lens and identify a contaminant state upon determining the contaminant is approaching the lens. The example vehicle also includes a nozzle to spray washer fluid to prevent contamination of the lens responsive to the controller identifying that the contaminant is a liquid.Type: GrantFiled: August 7, 2017Date of Patent: February 5, 2019Assignee: Ford Global Technologies, LLCInventors: Cheri Lyn Hansen, Haron Abdel-Raziq, Cynthia M.

Patent number: 10183565Abstract: A hydrostatic drive has a hydrostatic pump (3) driven by a drive motor (2) and connected in a closed circuit with a hydrostatic motor (4). The closed circuit is formed by a first hydraulic connection (6a) and a second hydraulic connection (6b). Each of the hydraulic connections (6a, 6b) can form the high-pressure side or the low-pressure side of the closed circuit. A high pressure accumulator device (20) can be connected with the respective high-pressure side hydraulic connection (6a, 6b) and, simultaneously, the respective low-pressure side hydraulic connection (6b, 6a) can be connected with a hydraulic balancing device (30). A valve device (50) is provided for this simultaneous connection. The valve device (50) is a hydraulically controlled shuttle valve device (51) connected to the two hydraulic connections (6a, 6b), the high pressure accumulator device (20) and the hydraulic balancing device (30).Type: GrantFiled: December 2, 2014Date of Patent: January 22, 2019Assignee: Linde Hydraulics GmbH & Co.
