Abstract
A drive unit for vehicles prevents the rise of temperature of a high-pressure battery or condenser and assists the vehicle engine using a motor activated by an electric current supplied from the battery. The drive unit includes a battery temperature sensor and battery ammeter sensor, and defines the permissible current value of input-and-output current, which is limit of a current value to be inputted-and-outputted with respect to the battery, based on the difference between the battery temperature and the upper limit. When the battery temperature exceeds the threshold temperature, the permissible current value is set. Moreover, when the exchanged current value of the output-and-input current exceeds the permissible current value, the motor gradually decreases the output command value.
