Abstract
A system for estimating torque in a locked vehicle system may include a locking mechanism comprising a stiff material. The system may further include a controller configured to estimate an amount of torque in the locked vehicle system based on a deformation of the stiff material.
Claims20
A system for estimating torque in a locked vehicle system, comprising:
- a locking mechanism comprising a stiff material;
- and
- a controller configured to estimate an amount of torque in the locked vehicle system based on a deformation of the stiff material.
A system for estimating torque in a locked adaptive steering system, comprising:
- a locking mechanism comprising a solenoid surrounded by a stiff material, the locking mechanism being configured to transition the adaptive steering system between an unlocked state and a locked state;
- a motor angle sensor configured to measure a rotational displacement of an adaptive steering system motor, while the adaptive steering system is in the locked state;
- and
- a controller communicatively coupled to the motor angle sensor,
- wherein the controller is configured to calculate a deformation of the stiff material based on the measured rotational displacement and estimate an amount of torque in the adaptive steering system, while the adaptive steering system is in the locked state, based on the deformation.
