摘要： A torque detection mechanism can be provided for a power train and its control unit without newly adding a sensor and its signal processing module. As a gear pair for the torque detection mechanism of a phase difference type, existing gears in a transmission are used, or a gear pair for this mechanism are provided adjacent to these existing gears. From phase signals sent from pickups, a phase difference signal is obtained by use of one part of existing devices in the control unit. The torque detection mechanism can be realized with the minimum number of component parts by utilizing the existing members and spaces instead of newly adding a sensor and its module. The invention can be applied to either of FF and FR cars, and has a practical structure in respect of the performance, costs and reliability.

摘要： An engine control apparatus for shifting an ignition timing signal to an ignition coil (48) so that the engine produces optimum torque generates a pseudo random signal (26) which is preferably an M series signal and applies the pseudo random signal to a parameter of the engine having a noise frequency component such as the engine rotational speed y(t). The M series signal is a signal having a impulse type self correlation function. A mutual correlation function of the number of revolutions of the internal combustion engine and of the M series signal is computed (30-44) and an optimum ignition advance angle is supplied to an adder (46). The adder (46) combines the optimized signal ignition advance angle with a basic ignition timing signal (.theta..sub.advB) to provide an ignition timing signal (.theta.ig) to the ignition coil (48).
