Method for drive control

A method for a drive control of actuators of at least one wheel of a vehicle, comprising the following steps:

• sensing a desired acceleration;
• sensing a vehicle velocity of the vehicle;
• sensing a wheel velocity of the wheel;
• determining a status description of the wheel from the wheel velocity and a wheel acceleration, wherein the status description includes a static description which is a function of the wheel velocity and of the wheel acceleration;
• determining a first value of a target wheel acceleration from the status description, a slip of the wheel, and the desired acceleration, wherein the slip is a function of the wheel velocity and the vehicle velocity;
• determining a second value of the target wheel acceleration from the wheel velocity, the wheel acceleration, and the slip, wherein the second value is a function of correction factors of at least one matrix;
• determining a third value of the target wheel acceleration, the third value controlling the actuators of the at least one wheel, wherein the third value is a function of the first value and of the second value;
• sensing the third value of the target wheel acceleration for at least one situation, wherein the situation includes the wheel velocity, the wheel acceleration, and a wheel dynamic;
• comparing the third value to a corresponding correction factor of the at least one matrix;
• and
• entering an update of the third value into a corresponding element of the at least one matrix when the slip is lower when using the third value than when using the corresponding correction factor of the at least one matrix.
