Abstract: Systems and method for assigning vehicle suspension dynamics are disclosed. Control signals that correspond to a current driving dynamic of a suspension system of a vehicle are generated. A vehicle state associated with the generated control signals is computed and a non-traditional suspension mode is selected. Based on the computed vehicle state and the selected suspension mode, a suspension height of the vehicle is adjusted.

Abstract: A trailer backup assist system is provided herein. The system includes a calibration feature for calibrating an imaging device used for hitch angle detection. The system also employs multiple hitch angle detection methods, a number of which may run in parallel to increase the intervals at which a hitch angle can be measured. The system additionally includes a predictive feature in which a hitch angle can be predicted in instances where a trailer sensing device fails. The system is further configured to estimate a trailer length and generate steering commands that are invariant to the estimated trailer length under certain conditions.

Abstract: Systems and methods for curb detection for parking are disclosed. An example vehicle parking assist system includes a processor and memory. An example program stored in the memory is configured to move a vehicle using a set of maneuvers to park the vehicle in a parking space based on an estimated location of a curb. The example program is also configured to compare a first yaw rate to a reference yaw rate to detect when the vehicle contacts the curb. Additionally, the example program is configured to move the vehicle using an adjusted set of maneuvers based on an actual location of the curb.

Abstract: A method of operating a transmission includes measuring an output torque, estimating a gearbox input torque using a model, and estimating gearbox component torques based on a detailed gearbox model. The model used to estimate the input torque varies depending on whether a torque converter is locked, open, or slipping. In some operating conditions, multiple estimates are available for gearbox input torque, impeller torque, or shift element torque in which case the models are adapted. When an estimated component torque is outside an expected range, a warning flag is raised and diagnostic data is saved. When an estimated torque approaches or exceeds a torque limit, the input torque command may be reduced to prevent component damage. A warning flag may also be raised and diagnostic data saved in response to a model parameter being adapted to a value outside of a predetermined range.

Abstract translation: 操作变速器的方法包括测量输出转矩，使用模型估计变速箱输入转矩，以及基于详细的变速箱模型来估计变速箱分量转矩。 用于估计输入转矩的模型取决于变矩器是否锁定，打开或滑动。 在某些操作条件下，齿轮箱输入扭矩，叶轮扭矩或换档元件扭矩可用于多种估计，在这种情况下，适用型号。 当估计的分量转矩超出预期范围时，会提醒警告标志并保存诊断数据。 当估计转矩接近或超过转矩极限时，可以减小输入转矩指令以防止元件损坏。 还可以提出警告标志，并且响应于模型参数保存的诊断数据适应于超出预定范围的值。

Abstract: A trailer backup assist system for a vehicle reversing a trailer includes a sensor module adapted to attach to the trailer and generate a trailer yaw rate or a trailer speed. The trailer backup assist system also includes a vehicle sensor system that generates a vehicle yaw rate and a vehicle speed. Further, the trailer backup assist system includes a controller that estimates a hitch angle based on the trailer yaw rate or the trailer speed and the vehicle yaw rate and the vehicle speed in view of a kinematic relationship between the trailer and the vehicle.
