Abstract
A method for performing brake disc cleaning of an at least partially electrically driven vehicle including a brake system with at least one friction brake, the surface of which can be brought into contact with a corresponding brake disc, the method includes: determining an upcoming brake event by using at least vehicle-ahead information, predicting a needed deceleration level of an ego-vehicle by using the vehicle-ahead information, and carrying out a brake disc cleaning of the friction brake only in case the needed deceleration level of the ego-vehicle in the upcoming brake event is predicted as being above a predefined value.

A method for performing brake disc cleaning of an at least partially electrically driven vehicle comprising a brake system with at least one friction brake, a surface of the friction brake brought into contact with a corresponding brake disc, the method comprising:
- determining an upcoming brake event of the at least partially electrically driven vehicle by using at least vehicle-ahead information of a vehicle ahead,
- predicting a needed deceleration level of the at least partially electrically driven vehicle by using the vehicle-ahead information, and
- carrying out the brake disc cleaning of the friction brake of the at least partially electrically driven vehicle only in case the needed deceleration level of the at least partially electrically driven vehicle in the upcoming brake event is predicted as being above a predefined value.
A non-transitory computer-readable medium comprising instructions stored in a memory and executed by a processor to carry out steps comprising:
- for performing brake disc cleaning of an at least partially electrically driven vehicle comprising a brake system with at least one friction brake, a surface of the friction brake brought into contact with a corresponding brake disc,
- determining an upcoming brake event of the at least partially electrically driven vehicle by using at least vehicle-ahead information of a vehicle ahead,
- predicting a needed deceleration level of the at least partially electrically driven vehicle by using the vehicle-ahead information, and
- carrying out the brake disc cleaning of the friction brake of the at least partially electrically driven vehicle only in case the needed deceleration level of the at least partially electrically driven vehicle in the upcoming brake event is predicted as being above a predefined value.
An at least partially electrically driven electric vehicle, comprising:
- a brake system with at least one friction brake, a surface of the friction brake brought into contact with a corresponding brake disc,
- one or more units configured to acquire vehicle-ahead information,
- one or more units configured to acquire vehicle information of the at least partially electrically driven vehicle, and
- at least one control unit configured to:
- for performing brake disc cleaning,
- determining an upcoming brake event of the at least partially electrically driven vehicle by using at least vehicle-ahead information of a vehicle ahead,
- predicting a needed deceleration level of the at least partially electrically driven vehicle by using the vehicle-ahead information, and
- carrying out the brake disc cleaning of the friction brake of the at least partially electrically driven vehicle only in case the needed deceleration level of the at least partially electrically driven vehicle in the upcoming brake event is predicted as being above a predefined value.
