Abstract
Systems, apparatus, articles of manufacture, and methods are disclosed Steering load detection systems and related methods are disclosed. An example apparatus includes memory; machine-readable instructions; and at least one programmable circuit to at least one of instantiate or execute the machine-readable instructions to determine an acceleration of a rack of a steering system of a vehicle based on one or more of position data for a shaft of a pinion of the steering system or position data for a shaft of a motor of the steering system; determine a force applied to a tie rod of the vehicle based on the acceleration of the rack; and cause a message to be output based on the force.
Claims20
An apparatus comprising:
- memory;
- machine-readable instructions;
- and
- at least one programmable circuit to at least one of instantiate or execute the machine-readable instructions to:
- determine an acceleration of a rack of a steering system of a vehicle based on one or more of position data for a pinion shaft coupled to a pinion of the steering system or position data for a shaft of a motor of the steering system;
- determine a force applied to a tie rod of the vehicle based on the acceleration of the rack;
- and
- cause a message to be output based on the force.
At least one non-transitory machine-readable medium comprising machine-readable instructions to cause at least one programmable circuit to at least:
- generate, based on first angular position data, translational acceleration data for a rack of a steering system of a vehicle, the first angular position data corresponding to one or more of outputs of a first position sensor associated with a pinion shaft of the steering system at a first time or outputs of a second position sensor associated with a shaft of a motor of the steering system at the first time;
- predict, based on the translational acceleration data, an excessive force event associated with a force applied to a component of the steering system;
- determine, based on second angular position data, an angle of a steering wheel of the vehicle, the second angular position data corresponding to one or more of outputs of the first position sensor at a second time or outputs of the second position sensor at the second time, the second time after the first time;
- and
- cause a message to be output for presentation based on the prediction of the excessive force event and the angle of the steering wheel.
A vehicle comprising:
- a steering system including a rack, a tie rod coupled to the rack, a pinion, and a pinon shaft coupled to the pinion;
- a position sensor to generate outputs indicative of angular positions of the pinon shaft;
- machine-readable instructions;
- and
- at least one programmable circuit to execute the machine-readable instructions to:
- determine, based on the outputs of the position sensor, an acceleration of the rack, the acceleration associated with linear motion of the rack;
- determine, based on the acceleration of the rack, a force applied to the tie rod;
- and
- cause a message to be displayed on an interface of a dashboard of the vehicle based on the force.
