Abstract: According to one or more embodiments, a steer by wire steering system includes a handwheel, and a handwheel actuator configured to secure a position of the handwheel. The securing includes determining a transition of the steer by wire steering system to an ingress/egress mode. The securing further includes, based on the determination that the steer by wire steering system is in the ingress/egress mode, computing a holding torque command based on a difference in a present angle of the handwheel and a target angle of the handwheel, which is caused by an input torque. Further, the securing includes generating a holding torque corresponding to the holding torque command to secure the position of the handwheel.

Abstract: According to one or more embodiments, a motor control system includes a first controller computing a first torque command using a first closed loop. The motor control system further includes a second controller computing a second torque command using a second closed loop. Both, the first controller and the second controller, compute the respective first torque command and the second torque command using a uniform calculation in which a pseudo/leaky integrator Ki s + ɛ in s domain (s is Laplace variable) is used and integrator state is calculated as Ki * ∫0te(τ)exp(Åτ−∈t)dτ, in time domain, which is implemented by discretization methods in electric control unit (ECU), where e is a tracking error, Ki is a predetermined integral parameter, and E is a configurable parameter. The motor control system further includes a motor that receives a torque command for generating corresponding amount of torque based on the first torque command and the second torque command.

Abstract: A method for monitoring vehicle inertia parameters in real-time includes receiving at least one lateral dynamic value. The method also includes calculating at least one vehicle inertia parameter value using the at least one lateral dynamic value. The method also include determining a difference between the calculated at least one vehicle inertia parameter value and a corresponding baseline vehicle inertia parameter value. The method also includes, based on a comparison between the difference between the calculated at least one vehicle inertia parameter value and the corresponding baseline vehicle inertia parameter value and a threshold, selectively controlling at least one vehicle operation based on the calculated at least one vehicle inertia parameter value.

Abstract: Technical solutions described herein include a method of controlling, in an electric power steering system, a steering angle according to a target steering angle by computing an initial value of an integral control term in a proportional integral derivative (PID) control loop used to calculate a control output signal, such as a motor torque command. The initial value of the integral control term is computed as a negative of the initial value of the feedforward term minus the initial value of the feedback term. The initial value of the integral control term corresponds to an initial value of a control output. Accordingly, the technical solutions described herein facilitate handling non-zero initial condition in Electric Power Steering angle control.
