Title:
POWER PLANT CONTROL DEVICE
Document Type and Number:
Japanese Patent JPH01208240
Kind Code:
A
Abstract:
PURPOSE:To accomplish a control in which the starting and accelerating characteristics and the slip converging characteristic are made compatible, by conducting a slip convergence with the weight put on the slip converging characteristic by the additional use of a transmission torque dropping means in case the slip does not converge satisfactorily. CONSTITUTION:A slip sensing means 52 senses the slip condition of the driving wheels 56 of a car. An engine output dropping means 53 drops the output of the engine 2 when slip is generated at the driving wheels 56. If the result is satisfactory convergence of the slip, the slip convergence control is finished, but if this slip convergence control by engine output dropping means 53 does not result in sufficient convergence of the slip, a torque transmission ratio dropping means 54 is additionally used to drop the torque transmission ratio in automatic transmission 3. An operation priority means 55 gives the engine output dropping means 53 priority to the torque transmission ratio dropping means 54.
