Title: Car slip controller
Inventor: INAGAKI TAKAFUMI
IPC: F02D41/00
Filed: 1985-06-08
Abstract: PURPOSE:To perform accurate slip control, by installing a slip judging device which performs a slip judgment in a way of comparing the detected value of driving wheel revolving speed with that of driven wheel revolving speed. CONSTITUTION:Driving wheel revolving speed is detected from a speedometer cable by a detecting device M2, while driven wheel revolving speed is detected with a signal of the magnet or the like attached to a driven wheel by a detecting device M3, and the ratio of between both is calculated as a steady driving rotational difference factor by a calculating device M4. Using this different ratio, the driving wheel revolving speed is compensated by a compensating device M5, and the presence of a slip is judged from the comparison between this compensated value and the detected value of the driven wheel revolving by a slip judging device M6. On the basis of this judgment, output of an internal- combustion engine is reduced with methods of reductions in a suction air quantity and a fuel supply or a timing delay of ignition timing or the like, thus a car slip is controlled.

Abstract: PURPOSE:To prevent an engine from being stopped while properly judging its idle state by taking the number-of-revolution of an engine as one of the conditions for judging the idle state along with the additional information on clutch connection or disconnection caused by a clutch switch. CONSTITUTION:When the number-of-revolution of an engine is more than a prescribed one in the first step 4, idle number-of-revolution control is not performed, and when it is less than the prescribed value, a control operation progresses to the second step 5 and if an acceleration pedal is not operated, the corresponding control is performed. If the acceleration pedal has been stepped in, the control operation progresses to the third step 6 and if a transmission gear is in a neutral position, the corresponding control is performed. If said gear is not in the neutral position, the control progresses to the fourth step 7, and if a clutch is disconnected, the corresponding control is performed. If connected, the corresponding control is not performed. Engine stoppage is prevented in such a way.
