    摘要： A coordinated regenerative brake system controls total brake torque to brake a vehicle in accordance with brake pedal operation and achieve deceleration intended by the driver's operation of the brakes when the accelerator is not depressed. In a vehicle speed range below specific speed V1, engine brake equivalent torque Ta is set to decrease gradually to zero in accordance with vehicle speed V. When brake operation starts at a vehicle speed exceeding V1, the desired total brake torque Tq working on the vehicle is the sum of brake torque Tb corresponding to brake operation, and engine brake equivalent torque Ta, until vehicle speed reaches specific speed V1. When vehicle speed is V1 or less, brake torque is controlled using as desired total brake torque Tq the sum of brake torque Tb corresponding to brake operation, and first engine brake equivalent torque Ta1, if brake operation amount Sb is greater than or equal to a first brake operation amount Sb1.

    摘要： A vehicle control apparatus performs regenerative braking by regeneratively operating first and second motor-generators to apply first and second braking torques in response to a deceleration request. The vehicle control apparatus is improves the efficiency in regeneratively generating electric power without greatly disturbing the balance between the. The control apparatus calculates an ideal front-rear wheel distribution ratio for front wheel braking torque and the rear wheel braking torque, and also calculates a distribution allowance for the ideal front-rear wheel distribution ratio. The control apparatus then corrects the ideal front-rear wheel distribution ratio within the distribution allowance such that the electric power generation efficiencies of the first motor-generator connected to the rear wheels and the second motor-generator connected to the front wheels are increased. Based on the corrected front-rear wheel distribution ratio, the control apparatus calculates the torque command values to be sent to the motor-generators.

    摘要： A braking and driving force control apparatus and method are for a vehicle having a frictional braking device for applying a braking force individually to each wheel and a regenerative braking device for generating a common braking force to a plurality of wheels. A target braking force is calculated on the basis of a driver's braking operation or traction control. The regenerative braking device is controlled so as to achieve the smallest target braking force of the target braking forces of the plurality of wheels. The frictional braking device is controlled so as to achieve the target braking force of another wheel, different from the wheel having the smallest target braking force, in cooperation with the regenerative braking device. Thus, the efficiency of regenerating energy is enhanced.
