Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to improve electronic power assisted steering in a vehicle. An example apparatus includes memory and a processor to execute instructions to determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle, determine a steering column torque derivative based on a derivative of the steering column torque, determine a compliance compensation torque based on the steering column torque and the steering column torque derivative, and adjust a steering response of the steering column based on the compliance compensation torque.
Claims20
An apparatus comprising:
- memory;
- and
- a processor to execute instructions to:
- determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle;
- determine a steering column torque derivative based on a derivative of the steering column torque;
- determine a compliance compensation torque based on the steering column torque and the steering column torque derivative;
- and
- adjust a steering response of the steering column based on the compliance compensation torque.
A non-transitory computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
- determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle;
- determine a steering column torque derivative based on a derivative of the steering column torque;
- determine a compliance compensation torque based on the steering column torque and the steering column torque derivative;
- and
- adjust a steering response of the steering column based on the compliance compensation torque.
