example 1

[0036] The following examples illustrate example systems and methods described herein. Example 1: An electric power steering system comprising: a steering rack having a first end and a second end; at least one damper coupled to one of the first end and the second end; a steering angle sensor; and An electronic controller configured to receive steering angle data from the steering angle sensor, compare the steering angle data to a threshold, and determine whether the at least one damper has been damaged based on the comparison.

example 2

[0037] Example 2: The system of Example 1, further comprising a steering shaft, a steering control device, and at least one wheel.

example 3

[0038] Example 3: The system of example 2, wherein the steering angle sensor detects steering angle data from at least one of a steering shaft, a steering control device, and the at least one wheel.

Abstract

The invention relates to detecting damage to components of an electric power steering system. The invention also relates to the electric power steering system. The system includes a steering rack having a first end and a second end and at least one damper coupled to one of the first end and the second end. The system also includes an electronic controller configured to determine if the damper has been destroyed based upon a sensed steering angle being above a maximum steering angle threshold or based upon a received signal from an electrical circuit enclosed within the at least one damper.

Description

technical field [0001] The invention relates to an electric power steering system. Background technique [0002] In an electric power steering ("EPS") system, an electric motor drives a gear to provide additional torque to the steering rack, which assists in turning the wheels of the vehicle. In general, an EPS system includes many components that are mechanically and electrically connected. These components can be damaged if the vehicle collides with external objects such as curbs, potholes and other vehicles. Often, the user of the vehicle may not be aware that the EPS system is damaged following a collision with an external object. Contents of the invention [0003] As mentioned earlier, damage to the EPS system may go undetected. Therefore, there is a need for a system to detect potential damage to components of EPS systems based on the operating parameters of the components. For example, as explained in more detail below, components may experience impact forces fr...
