Abstract
The invention is directed to a control method and a control arrangement for an adjusting device in a motor vehicle wherein at least two signal parameters of the drive signal are pregiven for driving the adjusting device alternately in time intervals. The signal parameters are pregiven to cause the actuating device to assume a desired position in time average.
Claims12
A method for controlling an actuating device in a motor vehicle having a motor for propelling said motor vehicle, the method comprising:
- detecting selected operating variables of at least one of said motor and said motor vehicle;
- generating an electric pulse-shaped drive signal for driving said actuating device and said drive signal having a parameter;
- computing a set value for said actuating device in dependence upon said selected ones of said operating variables;
- computing first and second values of said parameter in dependence upon said set value;
- generating a first component of said drive signal with said parameter corresponding to said first value thereof and generating a second component of said drive signal with said parameter corresponding to said second value thereof;
- and,
- alternately applying said first and second components of said drive signal to said actuating device for respective time intervals to drive said actuating device to assume said set value.
An arrangement for controlling an actuating device in a motor vehicle having a motor for propelling said motor vehicle, the arrangement comprising:
- PG,17
- sensing means for detecting selected operating variables of at least one of said motor and said motor vehicle;
- a control unit for generating an electric pulse-shaped drive signal for driving said actuating device and said drive signal having a signal parameter;
- said control unit including:
- means for determining a set value for said actuating device in dependence upon said selected ones of said operating variables;
- means for computing first and second values of said parameter in dependence upon said set value;
- means for generating a first component of said drive signal with said parameter corresponding to said first value thereof and for generating a second component of said drive signal with said parameter corresponding to said second value thereof;
- and,
- means for alternately applying said first and second components of said drive signal to said actuating device for respective time intervals to drive said actuating device to assume said set value.
