エネルギ回生装置。 Brake energy regeneration uses a swash plate type pump motor connected to the wheel drive system via an electromagnetic clutch, and a high-pressure side accumulator and a low-pressure side accumulator connected to this pump motor to regenerate the brake energy recovered during deceleration as driving energy. The device includes means for detecting vehicle speed, means for detecting engine speed, means for detecting the control lever position of the fuel injection pump, means for detecting the pressures of the high pressure side and low pressure side accumulators, and these. means for calculating the required torque of the engine and the drivable torque of the pump motor based on the detected value and comparing the two torques, and according to the comparison, when the drivable torque is larger than the required torque during steady running; a first control means for controlling the swash plate angle of the pump motor in accordance with the required torque and the pressure difference between the two accumulators so that the vehicle is driven by the driving force of the pump motor, and disengaging the engine clutch to cut fuel injection; , when the drivable torque is smaller than the required torque during steady running, the engine clutch is connected so as to use the engine output, and the fuel injection amount is controlled according to the difference between the required torque and the drivable torque.
A brake energy regeneration device characterized in that it is provided with a control means.
