STEERING CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18525692 titled 'STEERING CONTROL DEVICE
Simplified Explanation
The abstract describes a servo controller that calculates a base assist command to ensure that a steering torque aligns with a target steering torque. It also includes features such as estimated load torque calculation, target steering torque calculation using a map, and a low-pass filter for differential control calculations.
- The servo controller calculates a base assist command to align steering torque with a target steering torque.
- An estimated load torque calculation section determines an estimated load torque based on the target steering torque and base assist command.
- A target steering torque calculation section uses a map to establish a relationship between estimated load torque and target steering torque.
- The servo controller includes a low-pass filter to remove high-frequency components in the input target steering torque for differential control calculations.
- Differential control amounts are calculated based on the steering torque deviation between the target steering torque after the low-pass filter and the actual steering torque.

Original Abstract Submitted
A servo controller calculates a base assist command so that a steering torque follows a target steering torque. An estimated load torque calculation section calculates an estimated load torque based on a target steering torque and a base assist command. A target steering torque calculation section calculates a target steering torque using a map that defines a relationship between the estimated load torque and the target steering torque. The servo controller has a low-pass filter for removing high-frequency components of a predetermined frequency or higher in the input target steering torque at least in a differential control calculation, and calculates a differential control amount according to a steering torque deviation between the target steering torque after the low-pass filter and the steering torque.
