Abstract:
1. A vehicle drive apparatus comprising: an electricity storage reservoir; and an electric motor, which is driven with electricity supplied by said electricity storage reservoir, for driving a vehicle or assisting said vehicle driven by an internal combustion engine, wherein said apparatus comprises: a temperature detecting means for detecting a temperature of said electricity storage reservoir; an upper limit setting means for setting an upper limit for discharge power of said electricity storage reservoir depending on said temperature; a power detecting means for detecting said discharge power of said electricity storage reservoir; a revolution speed detecting means for detecting a revolution speed of said internal combustion engine or electric motor; a torque setting means for setting torque requirement for said electric motor depending on said revolution speed; and a torque decreasing means for decreasing said torque requirement from a current torque requirement value to a new torque requirement value greater than zero when said discharge power is more than said upper limit when said internal combustion engine is started up by said electric motor.
