Abstract
A method for preventing a stationary vehicle from unintentionally rolling away. The transmission is not in a neutral position. By activating a brake, a holding mode is actuated whereby a brake is released, dependent upon the displacement of a clutch, which determines the actual takeover torque of the clutch and the holding mode can be deactivated.

A method for preventing a stationary vehicle from unintentionally rolling away, in a case of said stationary vehicle, a transmission is not in a neutral position and by way of an activation of a brake pedal (1) of a brake (11) a holding mode is created, the brake (11) is released in accordance with a displacement of a clutch, which is a determinant for actual takeover torque of the clutch and by this action, a holding mode can be deactivated, whereby the holding mode of the brake (11) can be adjusted by a timing delay, if no brake pedal has been activated for a predetermined time period.
A method for preventing a stationary vehicle from unintentionally rolling away, in a case of said stationary vehicle, a transmission is not in a neutral position further comprising the steps of:
- creating a holding mode by activation of a brake pedal (1) of a brake (11);
- releasing the brake (11) in accordance with displacement of a clutch which is a determinant for actual takeover torque of the clutch;
- and, by this action,
- deactivating the holding mode whereby the holding mode of the brake (11) can be adjusted by a timing delay in the event that no brake pedal has been activated for a predetermined time period.
