Title:
SPEED CHANGE CONTROL APPARATUS FOR HYBRID VEHICLE, AND SPEED CHANGE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/118255
Kind Code:
A1
Abstract:
A speed change control apparatus for a hybrid vehicle having a differential mechanism that transmits motive power outputted from an internal combustion engine to a first motor and an output member separately, and a second motor that exchanges torque with a wheel is provided with: a first output control means that, at the start of a speed change, issues an instruction for changing the output of the internal combustion engine in a direction that promotes a change in rotational speed of the internal combustion engine by the speed change; a first rotational speed control means that continues control that has been exerted on the first and second motors prior to the speed change until a time corresponding to a response delay of the internal combustion engine elapses from the point of time of the instruction; a second rotational speed control means that controls the first motor such that the rotational speed of the internal combustion engine is changed in a direction changed by the change in the output of the internal combustion engine when the time corresponding to the response delay has elapsed; and a second output control means that issues an instruction for changing the output of the internal combustion engine to an output to be set after the speed change when the rotational speed of the internal combustion engine approaches a post-speed-change target rotational speed.
