In response to a driver's braking request operation, for example, the driver's depression of a brake pedal 85, a hybrid vehicle 20 sets a fraction of a regenerative braking torque by a motor MG2 and a fraction of a braking torque by a brake unit 90 relative to a preset braking torque demand Tr* according to the setting of a speed change ratio in a transmission 60 (steps S280, S290, S310, S320, S390, and S400). The hybrid vehicle 20 controls the motor MG2 to output the regenerative braking torque based on the preset braking torque demand Tr* and the set fraction of the regenerative braking torque, while controlling the brake unit 90 to enable the braking torque based on the preset braking force demand Tr* and the regenerative braking torque by the motor MG2 to be applied in a distributive manner at a preset front-rear braking torque distribution ratio ‘d’ to front wheels 39a and 39b and to rear wheels 39c and 39d.

The invention provides a switched reluctance motor torque control method and a modular power converter, the input of a rotating speed ring is a set reference rotating speed and a measured actual rotating speed, a rotating speed error is obtained, the rotating speed error is used as the input, and a total reference torque is obtained through PI control; the input of the torque ring is the total reference torque, the actual torque of each phase, the turn-on angle and the turn-off angle, and distributing the total reference torque to each phase by using a torque distribution function to obtain a phase reference torque; according to the numerical value relation between the phase reference torque and the actual torque of each phase, a pulse width modulation control signal is obtained through torque hysteresis, and the pulse width modulation control signal is applied to a corresponding switch tube in the modular power converter to complete control. On-line self-adjustment is carried out on an overlapping angle in a torque distribution function at each sampling moment, torque hysteresis is based on a pulse width modulation algorithm, pulse width modulation signals with different duty ratios and polarities are generated within a hysteresis limit, and free response is avoided.
