Abstract

A hybrid vehicle control system is configured to use automatic braking to compensate for an excess or deficiency of a braking force available from the power train of a hybrid vehicle that occurs when the hybrid vehicle switches from an electric drive (EV) mode to a hybrid drive (HEV) mode when the accelerator pedal depressing amount is detected as being substantially zero. In particular, hybrid vehicle control system determines whether a power train braking force from the power train is sufficient to achieve a target braking force. If the power train braking force is sufficient to achieve the target braking force when an accelerator pedal depressing amount is detected as being substantially zero, then a wheel brake is activated to apply a wheel braking force against a wheel of the vehicle to maintain the target braking force.

Description

technical field [0001] The present invention relates to a braking control system for a hybrid vehicle having: an electric drive (EV) mode in which drive wheels are driven solely by a motor / generator; and a hybrid drive (HEV) mode in which The drive wheels are driven by the engine and the motor / generator, or by the engine alone. More particularly, the present invention relates to a braking control system for a hybrid vehicle, which is arranged to perform coasting (inertia) motion braking force control. Background technique [0002] Japanese Patent Publication No. 11-082260 discloses an example of a conventional hybrid drive system used in a conventional hybrid vehicle. Such a drive control system for a hybrid vehicle proposed in Japanese Patent Publication No. 11-082260 has a motor / generator arranged between an engine and a transmission to be combined with a shaft guiding the rotation of the engine to the transmission; with a first A clutch is disposed between the engine an...
