1. A hybrid electric automobile comprising:

  • a vehicle body of a vehicle,a driving command means outputting a start signal for an advance and a start signal for a reverse of the vehicle by the passenger'"'"'s operation,a liquid fuel engine arranged at a front part of the vehicle body, and having an engine shaft rotated by combustion of a liquid fuel,a transmission mechanically connected to the engine shaft of the liquid fuel engine, accelerating or decelerating the rotation of the engine shaft, and having a driving shaft which outputs the accelerated or decelerated rotation of the engine shaft, the transmission ratio of the rotation of the driving shaft to the rotation of the engine shaft is 10 or less,first and second front wheels rotatably arranged on the right and left of the front part of the vehicle body and mechanically connected to the driving shaft of the transmission, and rotated by the engine shaft of the liquid fuel engine via the transmission,a liquid fuel tank arranged at a rear part of the vehicle body, and storing the liquid fuel to be supplied to the liquid fuel engine,first and second switched reluctance motors respectively arranged on the right and left of the rear part of the vehicle body, having an output shaft, and driving the vehicle in a direction in which the vehicle is moved forwards or backwards,first and second rear wheels rotatably arranged on the right and left of the rear part of the vehicle body, mechanically connected to the output shafts of the first and second switched reluctance motors via reduction mechanisms, respectively, and rotating by the rotation of the output shafts of the first and second switched reluctance motors,first and second inverters connected to the first and second switched reluctance motors, generating first and second motor driving signals for driving the first and second switched reluctance motors, and supplying the first and second motor driving signals to the first and second switched reluctance motors, respectively,a first battery connected to the first and second inverters, and supplying to the first and second inverters the electric power for generating the first and second motor driving signals,a first generator connected to the first battery and arranged in the vicinity of the liquid fuel engine, generating electric power by the rotation of the engine shaft of the liquid fuel engine, and supplying the generated electric power to the first battery,a plug-in device arranged at the vehicle body and connected to the first battery, having a connecting terminal with a home plug, and supplying the electric power from the home power source to the first battery,first and second front wheel rotation sensors provided in the vicinity of the first and second front wheels, and detecting rotational information on the first and second front wheels,first and second rear wheel rotation sensors provided in the vicinity of the first and second rear wheels, and detecting rotational information on the first and second rear wheels,a rotation signal processing means connected to the first and second front wheel sensors and the first and second rear wheel sensors, processing the rotational information on the first and second front wheels and the first and second rear wheels, and outputting the speed signal of the vehicle,a first control device connected to the rotation signal processing means, generating a first driving control signal which drives the first and second front wheels by the liquid fuel engine when the speed signal output from the rotation signal processing means exceeds a predetermined first value, and supplying a first driving control signal to the liquid fuel engine, anda second control device connected to the driving command means, the rotation signal processing means, and the first and second inverters, outputting to the first and second inverters an advance command signal which commands generation of the first and second motor driving signals for driving the vehicle in a direction in which the vehicle is moved forwards until the speed signal output from the rotation signal processing means reaches a predetermined second value greater than the first value upon receiving a start signal for an advance from the driving command means, and outputting to the first and second inverters a reverse command signal which commands generation of the first and second motor driving signals for driving the vehicle in a direction in which the vehicle is moved backward upon receiving a start signal for a reverse from the driving command means.
