Abstract
A method for evaluating the behavior of a vehicle component, including: issuing a control signal by a control unit of a motor vehicle to a vehicle component; detecting a response of the motor vehicle to the control signal; determining the behavior of the vehicle component; classifying the behavior of the vehicle component; and adapting the actuation of the motor vehicle component by the control unit. Also described is a related system.
Claims15
A method for evaluating a behavior of a vehicle component of a vehicle, the method comprising:
- issuing a control signal by a control unit of the vehicle to the vehicle component, wherein the vehicle component is a steering system or a brake system, and wherein the control signal is a steering intervention signal to the steering system or a brake signal to the brake system;
- detecting a response of the vehicle component and the vehicle to the control signal;
- determining the behavior of the vehicle component based on the detected response to the issued control signal, the determined behavior being a dead time, the dead time being a length of time from when the control signal was issued to the vehicle component until a time when the vehicle component became effective in response to the issued control signal;
- classifying the determined behavior of the vehicle component;
- and
- adapting an actuation of the vehicle component by the control unit based on a result of the classifying;
- wherein the vehicle component is a brake system of the vehicle or a steering system of the vehicle,
- wherein the behavior of the vehicle component changes as a result of wear to the vehicle component, and wherein the wear influences control performance of an automatic or autonomous control of the vehicle, and
- wherein the actuation of the vehicle component is adapted to the changes in the behavior of the vehicle component to improve the control performance of the vehicle component.

A system for evaluating a behavior of a vehicle component of a vehicle, comprising:
- a control unit;
- at least one sensor for detecting a behavior of the vehicle and the vehicle component;
- and
- the vehicle component, which is controlled;
- wherein the control unit is configured to perform the following:
- issuing a control signal by the control unit of the vehicle to the vehicle component, wherein the vehicle component is a steering system or a brake system, and wherein the control signal is a steering intervention signal to the steering system or a brake signal to the brake system;
- detecting a response of the vehicle to the control signal;
- determining the behavior of the vehicle component based on the detected response to the issued control signal, the determined behavior being a dead time, the dead time being a length of time from when the control signal was issued to the vehicle component until a time when the vehicle component became effective in response to the issued control signal;
- classifying the detected behavior of the vehicle component;
- and
- adapting an actuation of the vehicle component by the control unit;
- wherein the vehicle component is a brake system of the vehicle or a steering system of the vehicle,
- wherein the behavior of the vehicle component changes as a result of wear to the vehicle component, and wherein the wear influences control performance of an automatic or autonomous control of the vehicle, and
- wherein the actuation of the vehicle component is adapted to the changes in the behavior of the vehicle component to improve the control performance of the vehicle component.
