Hybrid vehicle starting control system

Abstract

This starting control device for a hybrid vehicle drives a drive wheel by means of at least one of an internal combustion engine and a drive motor and includes a push start control unit that enables the internal combustion engine to start by applying physical force to a hybrid vehicle when a generator in the hybrid vehicle starts the internal combustion engine by means of power supplied to the generator from a drive battery but the remaining battery power of the drive battery is less than the amount required by the starting control device to start the internal combustion engine, or when the battery temperature of the drive battery is less than a temperature at which it is possible to store power. The push start control unit switches a clutch from a disengaged state to a connected state when the wheel speed of the drive wheel exceeds a preset speed.

Claims

1. A starting control device for a hybrid vehicle that drives the drive wheels with at least one of a drive motor or an internal combustion engine, The aforementioned hybrid vehicle is A generator driven by the aforementioned internal combustion engine, A drive battery for storing electricity generated by the aforementioned generator, A clutch for transmitting or interrupting power between the internal combustion engine and the drive wheel, A push-start mode switch for enabling the starting of the internal combustion engine, A guidance device that instructs the driver of the aforementioned hybrid vehicle on how to push-start the vehicle, Equipped with, The generator starts the internal combustion engine using electricity supplied from the drive battery, The starting control device includes a push-start control unit that enables the starting of the internal combustion engine by applying physical force to the hybrid vehicle when the remaining charge of the drive battery is insufficient to start the internal combustion engine, or when the battery temperature of the drive battery is below the temperature at which it can store electricity, A display control system that instructs the guidance device to perform a push-start operation when the remaining charge of the drive battery is insufficient to start the internal combustion engine, or when the battery temperature of the drive battery is below the temperature at which it can store energy, It has, The push-start control unit enables switching the clutch from a disengaged state to an engaged state when the internal combustion engine becomes ready to start via the push-start mode switch, and switches the clutch from a disengaged state to an engaged state when the vehicle speed of the hybrid vehicle exceeds a predetermined speed. A starting control device for hybrid vehicles.
