SYSTEM FOR CONTROL IN START ACCELERATION OF HYBRID VEHICLE, HYBRID VEHICLE, AND METHOD FOR CONTROL IN START ACCELERATION OF HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a system for control in start acceleration of a hybrid vehicle, a hybrid vehicle and a method for control in start acceleration of a hybrid vehicle, which can quickly and surely suppress surge behavior occurring in the hybrid vehicle in start acceleration of the hybrid vehicle while preventing deterioration of exhaust gas performance and fuel economy.SOLUTION: A system for control in start acceleration of a hybrid vehicle exerts control of: at the time of start acceleration of the hybrid vehicle, perform estimation calculation of a surge behavior suppression torque ΔT, which is the torque of an opposite phase to a surge behavior torque generated in the hybrid vehicle and is the torque for suppressing the surge behavior torque, on the basis of a vehicle speed, an engine rotation speed, a gear stage of a transmission connected to an engine and an accelerator opening; and making a motor generator generate the estimation-calculated surge behavior suppression torque ΔT.SELECTED DRAWING: Figure 2
