Title:
車両駆動ユニットの制御方法および装置
Document Type and Number:
Japanese Patent JP4225601
Kind Code:
B2
Abstract:
The invention is directed to a method of controlling a drive unit of a motor vehicle wherein the drive unit is controlled in dependence upon at least one operating variable. The operating variable is detected with at least first and second measuring devices as first and second quantities, respectively, thereby providing a redundant detection of the operating variable. The two measuring devices are mounted so that they move in synchronism with each other within a predetermined tolerance. The second quantity is checked for a fault utilizing a comparison in the context of the tolerance of the synchronism of movement. A fault without a movement out of the tolerance is detected when the value of the second quantity does not change in correspondence to the value of the first quantity within at least a predetermined value range of the operating variable. The invention is also directed to an arrangement of controlling the drive unit in dependence upon the operating variable.
