Method for modulating power steering assistance function in vehicles
A recently granted patent (Publication Number: US12012158B2) discloses a method for modulating the application of an assistance function in a power steering system of a vehicle. The method involves evaluating the application gain of the assistance function by estimating the assist torque associated with it and multiplying it by the application gain. This evaluation includes determining various gains based on factors such as yaw rate, steering wheel angle, vehicle speed, longitudinal acceleration, and lateral acceleration. The method aims to optimize the assistance function by adjusting the assist torque based on these factors, ultimately enhancing the vehicle's steering performance.
Furthermore, the patent also covers a power steering device for a vehicle that implements the aforementioned method. The device includes components such as at least two wheels, a steering wheel, an assist motor, and a driving motor. By utilizing the method described in the patent, the power steering device can effectively modulate the application of the assistance function, providing drivers with improved control and responsiveness while steering the vehicle. This innovation in power steering technology showcases a sophisticated approach to enhancing the driving experience by dynamically adjusting the assistance function based on various parameters to optimize steering performance and overall vehicle handling.
