In a hybrid car, or an electric motor-driven four-wheel-drive vehicle, in which an electric motor is driven directly by an output from a generator, vehicle running performance is enhanced. The output from the generator is controlled so as to maintain a generator torque in a range, in which the vehicle does not stall. Specifically, a driving apparatus for the hybrid car includes a second generator 2 driven by an engine 1 for driving one pair of either front or rear wheels 14, 15, an electric motor 5 driven through directly receiving the output from the second generator 2 and driving the other pair of either the front or rear wheels 14, 15, and a four-wheel-drive control unit 6 controlling driving of the second generator 2 and the electric motor 5. When the engine 1 is in an overloaded condition, the four-wheel-drive control unit 6 limits the output of the second generator 2.

The invention discloses a battery warm-up method for hybrid cars, and the method is that when the temperature of a car battery is lower, the battery can be recharged or discharged with small capacity to increase the internal temperature of the battery, so that the battery can work within the best using temperature range. The main steps are as follows: the temperature of storage batteries is checked and the car running state is determined; the SOC of the storage batteries is checked, if the SOC is lower than some set value, the rotating speed of an engine is increased in order to drive a hybrid motor to recharge the storage batteries; and if the SOC is higher than some set value, the storage batteries provide electricity for the hybrid motor to drive the engine until the electric energy is consumed to be lower than some set value, then the rotating speed of the engine is increased in order to drive the hybrid motor to recharge the storage batteries. The method makes use of the recharging or discharging work on the car storage batteries, so that the battery temperature is increased to the appropriate temperature without adding any hardware, and the method is simple and effective, and has high operability and practicability.

A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.
