Abstract

A system for controlling a brake force of a vehicle. In one embodiment, the system includes an electronic control unit including a controller, a plurality of sensors in electronic communication with the controller. Each of the sensors transmits sensor data to the controller. A user interface and a driver recognition system are in electronic communication with the controller, and a computer readable memory stores instructions executed by the controller. The instructions cause the controller to evaluate a driver identification data received from the driver recognition system, a driver preference data received from the user interface, and the sensor data received from the sensors. The instructions further cause the controller to classify and select a driver or a driving pattern class, execute a control algorithm to determine a driver dependent brake force based on at least one of the selected driver or driving pattern class, the driver preference data, and the driver identification data, and to regulate the brake force of the vehicle based on the driver dependent brake force.

Claims

1. A system for controlling a brake force of a vehicle, the system comprising:

an electronic control unit including a controller;

a plurality of sensors in electronic communication with the controller, each of the sensors transmitting sensor data to the controller;

a user interface and a driver recognition system in electronic communication with the controller; and

a computer readable memory storing instructions that, when executed by the controller, cause the controller to;

evaluate driver identification data received from the driver recognition system and driver preference data received from the user interface,

evaluate the sensor data received from the sensors,

classify and select a driver or a driving pattern class,

execute a control algorithm to determine a driver dependent brake force based on at least one of the selected driver or driving pattern class, the driver preference data, and the driver identification data, and

regulate the brake force of the vehicle based on the driver dependent brake force.

2. The system of claim 1 further comprising a brake system including an intelligent active brake force booster that, when executed by the controller, regulates the brake force of the vehicle.

3. The system of claim 1, wherein the computer readable memory further stores instructions from a driving pattern classification module that, when executed by the controller, evaluates the sensor data received from the sensors and classifies the driver or the driving pattern class based on the sensor data and the driver identification data.

4. The system of claim 3, wherein the driving pattern classification module classifies the driver or the driving pattern class based on predetermined classification rules that operate with statistical classification algorithms used in pattern recognition systems.

5. The system of claim 3, wherein the driving pattern classification module is a linear pattern classifier.

6. The system of claim 3, wherein the driving pattern classification module is a nonlinear pattern classifier.

7. The system of claim 3, wherein the driving pattern classification module includes a plurality of sub-classification modules that, when executed by the controller, create an independent sub-classification results and the driving pattern classification module analyzes these results to make a final classification selection.

8. The system of claim 1, wherein the computer readable memory further stores instructions from a driver recognition module that, when executed by the controller, evaluates the driver identification data that includes a driver ID code, a driver priority, a latest driving date, and a total driving hours.

9. The system of claim 1, wherein the computer readable memory further stores instructions from a driver preference module that, when executed by the controller, evaluates the driver preference data that includes a brake force preference data, a pedal feel preference data, and a pedal position preference data.

10. The system of claim 9, wherein the driver preference data accepts a predetermined format and is transferable between vehicles.

11. The system of claim 1, wherein the computer readable memory further stores instructions from a driver dependent brake force module that, when executed by the controller, determines the driver dependent brake force from a predetermined brake control data stored in a memory of the controller.
