MANUAL SPEED CHANGE FOUR WHEEL DRIVING CONTROLLER FOR ELECTRIC MOTOR TYPE FOUR WHEEL DRIVE VEHICLE

PROBLEM TO BE SOLVED: To propose a manual speed change four wheel driving control for preventing the generation of a feeling of deceleration in the manual speed change during the acceleration of an electric motor type four wheel drive vehicle. SOLUTION: In a four wheel drive vehicle where front wheels are driven through a manual transmission by an engine, and rear wheels are driven through a 4WD clutch by a motor, when it is decided that an accelerator opening is APO≤0 (accelerator pedal release) in an S23, and it is decided that a transmission clutch opening is CVO≥100% (transmission clutch release) in an S25, and it is decided that the vehicle is being accelerated in an S29, the 4WD clutch is engaged, and the rear wheels are connected to the motor in an S30, and a manual speed change target engine revolution speed tNe for performing power generation by which speed maintenance motor torque tTm can be generated is calculated in an S31, and the revolution speed Ne of the engine which drives a generator is controlled so as to be tNe in an S32, and target motor field electromagnetic currents Ifm corresponding to the speed maintenance motor torque tTm are commanded to the rear wheel driving motor in an S33.
