초록 ▼

When the remaining capacity of a battery on a hybrid vehicle is smaller than a threshold value or the battery is unable to output the amount of electric energy required to propel the hybrid vehicle with a propulsive electric motor, the engine is started by a generator which operates in a motor mode. After the engine has been warmed up, the generator operates in a generator mode to generate electric energy which is supplied to the battery and the propulsive electric motor. The threshold value for the remaining capacity of the battery is greater as the atmospheric pressure is lower. Therefore, if the hybrid vehicle is running under a low atmospheric pressure such as on a highland, the electric energy is supplied from the generator to the battery and the propulsive electric motor at an early stage where the capacity of the battery is relatively high. The generator also starts to generate electric energy when the battery is unable to output an amount of electric energy sufficient enough to propel the hybrid vehicle.

An electric generation control system for use on a hybrid vehicle having a vehicle propelling apparatus including a battery and a propulsive electric motor energizable by the battery, and an electric energy generating apparatus including an engine and a generator actuatable by the engine, the generator being operable in a motor mode in which the generator is energized by the battery to operate as a starter motor for starting the engine while the vehicle propelling apparatus is in operation, and a generator mode in which after the engine is started, the generator is actuated by the engine to generate electric energy to be supplied to the battery and/or the propulsive electric motor, said electric generation control system comprising: remaining capacity recognizing means for recognizing a remaining capacity of the battery; start signal outputting means for issuing a start signal to activate the electric energy generating apparatus when the remaining capacity of the battery as recognized by said remaining capacity recognizing means is either lower than a predetermined threshold value or sharply reduced; an exhaust gas sensor associated with the engine for detecting exhaust gases emitted from the engine; exhaust gas sensor activating means for energizing and activating said exhaust gas sensor based on said start signal; exhaust gas sensor activation determining means for determining whether said exhaust gas sensor has been activated or not after the exhaust gas sensor has started being energized; engine start signal outputting means for outputting a start signal to start the engine based on a signal, which indicates that said exhaust gas sensor has been activated, from said exhaust gas sensor activation determining means; cranking means for energizing the generator with the battery to operate the generator as the starter motor in the motor mode based on said start signal, and controlling the generator to equalize a rotational speed of the engine actuated by the engine to a predetermined starting rotational speed; engine control means for starting to supply fuel to the engine when the rotational speed of the engine reaches said predetermined starting rotational speed, and starting to combust the fuel in the engine while monitoring exhaust gases from the engine with said exhaust gas sensor; full-combustion determining means for determining whether combustion of the fuel in the engine has reached a fully combusted state representing stable fuel combustion in the engine; and generator operation switching means for switching operation of the generator from the motor mode to the generator mode based on a signal, which indicates that combustion of the fuel in the engine has reached the fully combusted state, from said full-combustion determining means.
