Method for starting engine of vehicle with hybrid transmission and apparatus for carrying out the method

摘要

A method for starting an engine (2) of a vehicle having a hybrid transmission (1) is provided. The hybrid transmission (1) is capable of providing motor running under a power of an electric motor (MG1, MG2) only and hybrid running under a power of both of the engine (2) and the electric motor (MG1, MG2). The power of the engine (2) is supplied to the hybrid transmission (1) by way of a clutch (3). The method includes, when the clutch (3) is engaged for starting the engine (2) during the motor running, issuing an engine start instruction when an engine speed (Ne) increases to a startable speed (Nig) with the progress of engagement of the clutch (3), and after the moment (t2) of issue of the engine start instruction, restricting increase of an engagement force of the clutch (3) and thereby suppressing the progress of engagement of the clutch (3). An apparatus for carrying out the method is also provided.
