    摘要: In a process for controlling the torque of an internal combustion engine, an automatic gear system driven by the internal combustion engine includes a gear control device (1) and the internal combustion engine has a control device which, based on speed, load and, where appropriate, temperature signals, controls an ignition angle of an ignition system and/or an injection pulse width of a fuel injection system. The gear control device (1), for its part, controls on the basis of speed and load requirement signals the gear changes of the automatic gear. To improve the control of the whole drive unit, for the purpose of reducing fuel consumption and having smooth gear changes, the computer systems of the gear control drive (1) and of the control (2) of the internal combustion engine constantly intercommunicate via interfaces (3), the control device (2) of the internal combustion engine receiving from the gear control (1), in a cyclic time beat, a percentage torque requirement (PLF) on the basis of which the control device (2) automatically influences the torque of the internal combustion engine.

    摘要: A shift control system for an automatic transmission which can be set both at main gear stages selected on the basis of the running state of a vehicle and at intermediate gear stages having gear ratios intermediate between those of the main gear stages. The shift control system comprises: a running state detector for detecting the running state; a shift decider for deciding a main gear stage to be set, on the basis of the running state detected; a condition decider for deciding whether or not a shift between the main gear stages decided by the shift decider satisfies a predetermined condition; and an intermediate stage setter for deciding an intermediate stage to be set in place of the main gear stage, which was decided by the shift decider, on the basis of the result decided by the condition decider.

    摘要: Slip control is carried out so as to reduce torque applied to the driven wheels by reducing torque generated by the engine when a slip value against the driven wheels on pavement is larger than a predetermined value. A shift characteristic of the automatic transmission interposed between the engine and the driven wheels is set as a first shift characteristic which is a basic characteristic at the time of ordinary running where no slip control is carried out and as a second shift characteristic set so as to become at least unlikely to cause downshifting during slip control compared with said first shift characteristic. As the slip control terminates, a return of the first shift characteristic is prohibited when the torque generated by the engine is large (for example, when a degree of operation of an accelerator is not zero) or when downshifting is caused if based on the first shift characteristics.
