Transient steering system for a steer-by-wire system for a vehicle

A transient steering system for a steer-by-wire system of a vehicle, the transient steering system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• calibrating a transient steering algorithm with a baseline steering ratio;
• receiving, at the transient steering algorithm, a first set of vehicle data, the vehicle data including one or more of a vehicle speed, a steering angle, lateral acceleration, a yaw rate, and steering wheel torque;
• manipulating, based on a steering wheel angle gradient, the baseline steering ratio;
• determining, via the transient steering algorithm, a phasing gain based on a proportional transient variable and the lateral acceleration and longitudinal acceleration;
• generating, via the transient steering algorithm, a first steering ratio in response to the first set of vehicle data, the first steering ratio being different from the baseline steering ratio;
• and
• adjusting, at the steer-by-wire system of the vehicle, a steering control based on the first steering ratio.
