Abstract

The invention relates to a method for actuating closing part systems with actuators (8) in motor vehicles. The actuators (8) in motor vehicles can be electrically or hydraulically operable drive mechanisms. The closing part components are optionally monitored by means of pinch prevention detectors (10) and adapters (17), which take external disturbance variables (2, 3) into account. In the case of controllers (27) of closing part systems, a vehicle inclination signal N_α (24), upon ascertainment of the controlling variable (5) Y(t), and in the case of regulators (20) a reference signal X_r(t) (15), is switched to a pinch prevention detector (10) downstream of them, which reference signal is modified by the vehicle inclination signal (27).

Claims

1. A method for actuating closing part systems with actuators (8) in motor vehicles, in which the actuators (8) are electrical or hydraulic drive components, and the closing part systems are optionally monitored by pinch prevention detection circuits (10) and adaptations (17), to which disturbance variables (2, 3) are applied, characterized in that in the case of controllers (27), a vehicle inclination signal Nα

(24), upon the ascertainment of the controlling variable (5) Y(t), and in the case of regulators (20), a reference signal (15) X_r(t) is sent to a pinch prevention evaluation circuit (10) connected downstream of these, which signal is modified by the vehicle inclination signal N_α

(24).

2. The method of claim 1, characterized in that in the case of controllers (27), the vehicle inclination signal N_α

(24) is detected via a sensor (28), which is associated with a further monitoring system in the motor vehicle.

3. The method of claim 2, characterized in that the vehicle inclination signal (24) N_α

is transmitted via a data bus (26), such as a CAN, between interfaces (25, 31) to two monitoring systems (23).

4. The method of claim 2, characterized in that the controlling variable Y(t) (5) of the controller (24) is compensated for by the inclination signal (24) N_α

of the inclination sensor (28).

5. The method of claim 1, characterized in that the reference signal X_r(t) (15) is a constant value, dependent on U_bat (2) , T (3) and N_α

(24).

6. The method of claim 1, characterized in that in the case of controlled systems (21), for regulating the controlled variable (6), the influence of the disturbance variables (2, 3, 24) is eliminated.

7. The method of claim 1, characterized in that the vehicle inclination signal N_α

(24) is furnished by a sensor (28), which is integrated directly with the control unit (23) of the closing part component.

8. The method of claim 3, characterized in that the internal data bus (26) is arranged for data exchange between the two interfaces (25, 31) of the two monitoring systems (23) vehicle internal data bus (26).
