MONITORING DEVICE FOR THE POSITION REGULATOR IN AN ELECTRONIC ACCELERATOR PEDAL |
摘要 |
A monitoring device for an electronic accelerator pedal (1) in a motor vehicle has an accelerator pedal position sensor (2) mechanically connected to the accelerator pedal (1), a butterfly valve (7), a servo-motor (5) for the butterfly valve (7) and a butterfly valve position sensor (6) mechanically connected thereto. A regulator (3) receives a desired value ( alpha D) from the accelerator pedal position sensor (2) and an actual value ( alpha A) from the butterfly valve position sensor (6) and controls an output stage (4) for the servo-motor (5) in response to the comparison. A substractor (14) in a slave circuit (12) forms the difference ( alpha E) between the desired ( alpha D) and actual ( alpha A) values of the butterfly valve opening angle. An integrator (16) integrates the control difference ( alpha E) and is re-set to zero when the control difference ( alpha E) is zero or changes sign, whereupon integration of the control difference ( alpha E) is resumed. A limit device (18) indicates to a master circuit (10) the presence of a fault condition when the integrator output exceeds a predetermined limiting value. |
