キエネルギ回生装置。 When the vehicle decelerates, the rotational force of the drive system drives a swash plate type pump motor to pump oil in the low-pressure side accumulator to the high-pressure side accumulator and accumulate it, thereby recovering brake energy. In the regeneration device, means for detecting the working pressure of the exhaust brake, means for detecting the working pressure of the service brake, pressure detecting means for the accumulators on the high pressure side and the low pressure side, means for detecting the vehicle speed, and a means for detecting the operating pressure of the service brake. means for detecting a position; and calculating a braking torque of the exhaust brake based on each of the detection signals when the exhaust brake is activated;
A brake energy regeneration device comprising means for controlling a swash plate angle of the pump motor according to the calculated value.
