DRIVING CONTROLLER FOR HYBRID CAR AND HYBRID CAR MOUNTED WITH THE SAME

摘要

PPROBLEM TO BE SOLVED: To prevent clutch sliding in a hydraulic control type transmission even when the number of revolutions of an engine decreases during engine traveling in a hybrid car configured so that driving force from a motor can be transmitted through the hydraulic control type transmission to a driven wheel. PSOLUTION: A torque limit level in a motor (MG2) is decided based on the number of revolutions Neg of an engine under the engine traveling of the hybrid car (S110). Furthermore, any one of the elimination of any torque limit (S130), the setting of a torque limit value (S170) or the setting of output torque as actually zero (S180) is executed according to the decided torque limit level. Thus, it is possible to prevent the generation of clutch sliding by limiting the output torque of the motor (MG2) when a supply oil pressure to the hydraulic control type transmission decreases due to the decrease of the number of revolutions of the engine.
