Abstract
A method for implementing a differential lock function for a vehicle. The vehicle is an all-wheel drive vehicle, and the differential lock function produces an interaxle lock acting between the front axle and the rear axle of the all-wheel drive vehicle. In response to incipient slippage of at least one driven wheel, the method implements the function of a differential lock, using actions carried out independently of the driver, on at least one arrangement for controlling the wheel torque. In this context, at least one setpoint value for a wheel torque to be set is selected for carrying out the actions executed independently of the driver.
Claims18
A method for implementing a differential lock function for a vehicle, comprising the steps of:
- before an actual slippage of at least one driven wheel occurs, determining whether the at least one driven wheel has a tendency to experience a wheelslip in order to detect a presence of an incipient slippage of the at least one driven wheel;
- implementing, in accordance with actions performed independently of a driver, a function of a differential lock in response to the incipient slippage of the at least one driven wheel, the function of the differential lock being implemented on at least one arrangement for controlling a wheel torque;
- and
- selecting at least one setpoint value for the wheel torque to be adjusted in order to perform actions executed independently of the driver.
