Abstract:
1. A hybrid driving apparatus comprising: a transmission that includes a rotatable output shaft connected to wheels of a vehicle; a hybrid motor connected to the transmission and operable as both a motor and a generator; a diesel engine having an exhaust brake shiftable between an operational state in which the exhaust brake produces a braking effect on the vehicle during deceleration of the vehicle and a non-operational state in which the exhaust brake does not produce the braking effect during deceleration of the vehicle; a clutch between the diesel engine and the hybrid motor, the clutch being operable to shift between a connected condition in which the clutch connects the diesel engine to the hybrid motor and a disconnected condition in which the clutch does not connect the diesel engine to the hybrid motor; a clutch control unit operatively connected to the clutch to shift the clutch between the connected condition and the disconnected condition; an accelerator sensor connected to an accelerator to output accelerator signals indicating whether or not the accelerator is being operated to accelerate the vehicle; a momentary switch operatively connected to the exhaust brake so that operation of the momentary switch causes the exhaust brake in the non-operational state to shift to the operational state; the clutch control unit shifting the clutch from the connected condition to the disconnected condition during driving of the vehicle when the exhaust brake is in the off state and the accelerator shifts from being operated to not being operated; and wherein the clutch control unit shifts the clutch from the disconnected condition to the connected condition during driving of the vehicle when the exhaust brake in the non-operational state is shifted to the operational state and the accelerator shifts from being not being operated to being operated as indicated by the accelerator sensor.
