Abstract

Control data such as an optimal filter coefficient or the like of an engine mount is obtained by adaptation control or the like with respect to a reference vehicle F provided with a reference engine mount 20k, and the control data is stored in a reference data map storage medium 35 as a reference data map. Mount characteristics of the reference engine mount and a mass-produced engine mount 20m are measured. A correction data map which is a deviation from the reference data map is obtained for the control data of the mass-produced engine mount from a difference between both the mount characteristics, and the correction data map is stored in the correction data map storage medium 36. Both the data map storage media are added to the active control apparatus of the mass-produced vehicle M. Using both the data maps, it is possible to appropriately and actively control the vibration of the mass-produced vehicle without variation.

Claims

1. A control data setting method of an active mount control apparatus in which a pulse signal of periodicity is applied from a vibration generating source of a vehicle to an active mount which is a mount having a vibrator provided in the vehicle to obtain said control data of said active mount in a frequency band to be controlled to suppress vehicle body vibration, thereby forming a data map, said data map is input to said active mount control apparatus which suppresses external force from said vibration generating source by controlling motion of said vibrator based on the control data, wherein a reference mount characteristic which is a mount characteristic of a reference active mount is previously measured, the control data of a reference vehicle having the reference active mount is obtained and this is determined as a reference data map,

a mass-produced mount characteristic which is a mount characteristic of at least one of mass-produced active mounts of a predetermined production unit is measured,

the reference mount characteristic and the mass-produced mount characteristic are compared with each other to form a correction data map for correcting deviation of control data corresponding to said mass-produced active mount from said reference data map, and said reference data map and said correction data map are input to said active mount control apparatus provided in a mass-produced vehicle having said mass-produced active mount.

2. A control data setting method of an active mount control apparatus according to claim 1, wherein said reference data map is previously input to said active mount control apparatus, and said correction data map corresponding to said mass-produced active mount mounted in a mass-produced vehicle is input.

3. A control data setting method of an active mount control apparatus according to claim 1, wherein said reference data map and said correction data map corresponding to a mass-produced active mount mounted to a mass-produced vehicle are integrally input to said active mount control apparatus.

4. A control data setting method of an active mount control apparatus according to claim 1, wherein a data storage medium stores said reference data map or said correction data map.

5. A control data setting method of an active mount control apparatus according to claim 1, wherein a data storage medium stores said reference data map and said correction data map.

6. A control data setting method of an active mount control apparatus according to claim 2, wherein said reference data map and/or said correction data map is input to said active mount control apparatus through a communication line.

7. A control data setting method of an active mount control apparatus according to claim 2, wherein a storage medium storing said reference data map or a storage medium storing said correction data map is formed, said storage medium is added to said active mount control apparatus.

8. A control data setting method of an active mount control apparatus according to claim 2, wherein a storage medium storing said reference data map and a storage medium storing said correction data map is formed, said storage medium is added to said active mount control apparatus.

9. A control data setting method of an active mount control apparatus according to claim 2, wherein either one of said reference data map and said correction data map is input to said active mount control apparatus through a communication line, and the other one of them is input to said active mount control apparatus by adding a storage medium which stores the other data map.

10. A control data setting method of an active mount control apparatus according to claim 3, wherein said reference data map and said correction data map input to said active mount control apparatus through a communication line.

11. A control data setting method of an active mount control apparatus according to claim 3, wherein a storage medium which stores said reference data map and said correction data map is added to said active mount control apparatus.
