The invention relates to an automatic energy-saving device for automotive pneumatic braking. The automatic energy-saving device comprises an air storage barrel, a power source, an air exhaust braking switch, an air exhaust braking valve, an air incoming one-way valve, an air exhaust braking cylinder and an electromagnetic valve, a movable end of the air exhaust braking switch is connected with the power source while a first stationary end of the air exhaust braking switch is connected with a power source end of the electromagnetic valve through a clutch pedal, a second stationary end of the air exhaust braking switch is connected with the power source end of the electromagnetic valve, the power source end of the electromagnetic valve is connected with an acceleration pedal linkage switch, a first end of the electromagnetic valve is communicated with a first end of the air storage barrel, a second end of the air storage barrel is communicated with an active braking pipe while a third end of the same is communicated with an engine air exhaust pipe through the air incoming one-way valve, the second end of the electromagnetic valve is communicated with the air exhaust braking cylinder, and a push rod of the air exhaust braking cylinder contacts with the air exhaust braking valve. An air compressor adopted for conventional automotive pneumatic braking is omitted in the automatic energy-saving device, so that power of an engine is saved, space occupied by the air compressor is saved, and the automatic energy-saving device is convenient and practical.
