An intelligent control system for continuous adjustment of automobile exhaust brake braking force comprises a brake pedal sensor, an engine speed sensor, a gearbox information sensor, an accelerator pedal sensor, a controller, an electronic control pressure control valve and an exhaust brake butterfly valve. The controller forms pressure control signal output of the electronic control pressure control valve according to displacement data, action duration data, rotation speed data, rotation speed duration data, clutch data and neutral gear data, the electronic control pressure control valve is used for receiving pressure control signals and changing pressure output of an air outlet, and the exhaust brake butterfly valve is used for outputting pressure change along with the air outlet and controlling corresponding opening angle of the butterfly valve. The intelligent control system for continuous adjustment of the automobile exhaust brake braking force is capable of continuously controlling an existing exhaust brake butterfly valve, timely adjusting exhaust brake braking force and improving linkage efficacy of exhaust brake and main brake. The invention further relates to a control method for the system.
Description
technical field [0001] The invention relates to an electromechanical control system, in particular to an electromechanical control system for automobile exhaust braking. Background technique [0002] Exhaust braking is a commonly used auxiliary braking method, which is mainly used in driving conditions that require continuous braking force, such as transport vehicles going down long slopes. The braking force drops due to the rapid temperature rise of the brake friction to ensure driving safety. [0003] At present, the exhaust brake of heavy-duty vehicles is realized by the exhaust brake butterfly valve installed on the exhaust pipe. When the exhaust brake butterfly valve is closed, the exhaust brake is executed to provide auxiliary braking force. When the exhaust brake butterfly valve is opened, Disengaging the exhaust brake does not provide auxiliary braking force. [0004] There are usually two ways to open / close the exhaust brake butterfly valve, one is to rely on the ...
