Abstract
A hybrid vehicle includes a first motor generator (1) and an engine (3) connected to first drive wheels (7) via a transmission (5), a second motor generator connected to a second drive wheel (17), a battery (8) electrically connected to the first and second motor generators (7,17), a sensor (25) which detects a running state of the vehicle, a sensor which detects a charge state of the battery (8), and a controller (10,11,12). The controller (10,11,12) controls a drive force of the engine (3) and the first motor generator (1) according to the running state of the vehicle and the charge state of the battery (8), and drives the second motor generator (2) by the battery (8) or the power generated by the first motor generator (1).
