摘要： Methods, systems and a vehicle control system for a vehicle is provided. The vehicle control system includes an Electric Power Steering System (EPS), and a sensor system including a vehicle dynamics sensor configured to provide vehicle dynamics data and a temperature sensor configured to provide measured outside temperature. A processor is in operable communication with the EPS and the sensor system. The processor is configured to execute program instructions. The program instructions are configured to cause the processor to: execute an automated lateral control algorithm based on the vehicle dynamics data to generate a steering command, adapt the automated lateral control algorithm based on the measured outside temperature so that the steering command compensates for changing lateral response of the vehicle as a result of changing environmental temperature; and provide the steering command to the EPS, wherein the EPS is configured to laterally control the vehicle based on the steering command.

摘要： A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

摘要： A pulley assembly for a steering assembly includes a motor disposed within a motor housing and having a motor shaft extending therefrom. The pulley assembly also includes a motor face plate having a motor pilot component extending therefrom in the same direction as the motor shaft extends away from the motor, the motor shaft extending through a hole in the motor face plate. The pulley assembly further includes an idler pulley post protruding from the motor housing and through the motor face plate in the substantially same axial direction of the motor shaft, the idler pulley post being radially offset from the motor shaft. The pulley assembly yet further includes a housing flange having a pilot bore to accommodate at least a portion of the motor pilot and the idler pulley post.

摘要： A wheel suspension system is disclosed. The wheel suspension system may include a suspension assembly that may include a sub-frame adapted to be connected to a reference frame of a vehicle, a wheel interface adapted to rotatably support a wheel of the vehicle and to define a wheel rotation axis and a wheel rotation plane, and one or more linking units. Components of the linking unit(s) may be pivotally connected to each other, to sub-frame and to the wheel interface using pivoting connection that may cause components of the linking unit(s) to rotate about axes that are substantially perpendicular to the wheel rotation axis. The components of the linking unit(s) may be dimensioned, and positions of the pivoting connections may be set to cause a substantially linear motion of the wheel interface along a reference wheel interface motion axis that is perpendicular to the wheel rotation axis.

摘要： A steering transmission for an electro-mechanical steering system for a vehicle includes an electric motor, a servo transmission, and an angle transmission for connecting a steering column of the steering system to a control stalk of the steering system. The angle transmission is a mechanically driven recirculating-ball transmission with a ball nut, which is engaged with a segment shaft of the steering transmission that is/can be connected to the steering stalk. A spindle of the recirculating-ball transmission is continuous. The spindle is connected to an output shaft of the servo transmission on one side. The servo transmission is/can be driven by the electric motor.

摘要： Model-based control of dynamical systems typically requires accurate domain-specific knowledge and specifications system components. Generally, steering actuator dynamics can be difficult to model due to, for example, an integrated power steering control module, proprietary black box controls, etc. Further, it is difficult to capture the complex interplay of non-linear interactions, such as power steering, tire forces, etc. with sufficient accuracy. To overcome this limitation, a recurring neural network can be employed to model the steering dynamics of an autonomous vehicle. The resulting model can be used to generate feedforward steering commands for embedded control. Such a neural network model can be automatically generated with less domain-specific knowledge, can predict steering dynamics more accurately, and perform comparably to a high-fidelity first principle model when used for controlling the steering system of a self-driving vehicle.
