Title:
HYBRID-VEHICULAR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2015044495
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control apparatus capable of reliably suppressing sliding-down of a hybrid vehicle on an inclined road, and preventing locking of a motor, the vehicle including a hydraulic power transmission between a drive wheel, and an engine and a motor.SOLUTION: In a first sliding-down suppression control by a first sliding-down suppression control part 108 when a vehicle is stopped on an inclined road, output torque of a motor MG is controlled so that a rotation speed NP of a pump turbine wheel (an input-side rotation member) of a torque converter 16 (a hydraulic power transmission), namely a rotation speed NMG of the motor MG is controlled at a target rotation speed NMG*; and when torque required to control a rotation speed NP of the pump turbine wheel of the torque converter 16 at the target rotation speed NMG* exceeds predetermined torque, an engine 14 is started, and therefore, output torque of the engine 14 can be used if the output torque of the motor MG is in a shortage at a rotation speed when engaged in sliding-down suppression control, making it possible to appropriately prevent a locking state of the motor MG.
