Vehicle with Controllable Clutch Between Front and Rear Axle and Method for Controlling Variable Clutch Engagement Ratio of the Clutch

A vehicle comprising

• a drive system for generating a drive torque and transmitting the drive torque to a front axle drive output shaft and a rear axle drive output shaft;
• with
• a controllable clutch arranged between the front axle drive output shaft and the rear axle drive output shaft for distributing the drive torque between the front axle drive output shaft and the rear axle drive output shaft according to a clutch engagement ratio;
• a first speed sensor for determining a rotational speed of the front axle drive output shaft;
• a second speed sensor for determining a rotational speed of the rear axle drive output shaft;
• a measuring unit for determining a pull force;
• and
• a control unit configured
• to determine a speed difference (V_d) between the rotational speed of the front axle drive output shaft and the rotational speed of the rear axle drive output shaft;
• to determine a first threshold value (V_t1) based on the pull force;
• to set the first threshold value (V_t1) as an active threshold value (V_ta);
• and
• to control the clutch engagement ratio of the controllable clutch in dependence on the speed difference (V_d) and the active threshold value (V_ta).
