Abstract
A controller for a vehicle, configured to determine a take-off intent, and, in response to determining the take-off intent, i) initiate a release of a brake for at least one wheel or wheel axle of the vehicle, and ii) inhibit an application of propulsion torque to the at least one wheel or wheel axle during a finite time period (TR) related to a time required for releasing the brake. Provided is also an automated brake-release system including such a controller, a vehicle, a method, computer program product and computer-readable storage medium.

A controller for a vehicle, configured to:
- determine a take-off intent;
- in response to determining the take-off intent:
- initiate a release of a brake for at least one wheel or wheel axle of the vehicle;
- and
- inhibit an application of propulsion torque to the at least one wheel or wheel axle during a finite time period related to a time required for releasing the brake;
- and
- determine and/or update a value of the finite time period by providing data, indicative of brake wear and/or clutch wear during take-off of the vehicle, to a reinforcement learning model trained to determine and/or update the value of the finite time period based on the data.
A method performed in a controller of a vehicle, comprising:
- determining a take-off intent;
- in response to determining the take-off intent:
- initiating a release of a brake for at least one wheel or wheel axle of the vehicle;
- and
- inhibiting an application of propulsion torque to the at least one wheel or wheel axle during a finite time period related to a time required for releasing the brake;
- and
- determining and/or updating a value of the finite time period by providing data, indicative of brake wear and/or clutch wear during take-off of the vehicle, to a reinforcement learning model trained to determine and/or update the value of the finite time period based on the data.
