Abstract

The invention provides an engine speed adjusting rate adjusting self-adaption method and system and a storage medium. The method comprises the steps that the current set rotating speed and the set maximum speed adjusting rate under the current gear are read; according to the set rotating speed and the actual inner torque value, the decrease start torque value corresponding to the set rotating speed under the current gear is obtained through the decrease start torque characteristic; according to the set rotating speed, the maximum inner torque value corresponding to the set rotating speed under the current gear is determined through the external characteristics of an engine; according to the set rotating speed, the set maximum speed regulation rate under the current gear and the decrease start torque value and the maximum inner torque value corresponding to the set rotating speed under the current gear, a speed decrease coefficient corresponding to the set rotating speed under the current gear is obtained through a maximum speed decrease equation; and according to the speed decrease coefficient corresponding to the set rotating speed under the current gear, the speed decrease coefficient parameter of the engine is renewed. Self-adaptive renewing of the engine speed decrease coefficient is performed according to the set rotating speed and the speed regulation rate, and the requirement of a user for freely selecting the speed regulation rate and the rotating speed of the engine is met.

Description

technical field [0001] The present application belongs to the technical field of engine speed regulation, and in particular relates to an engine speed regulation adjustment method, device and storage medium. Background technique [0002] At present, the maximum steady-state speed regulation of the traditional engine is determined by the deceleration coefficient and the take-off torque calibrated inside the electronic control unit ECU (Electronic Control Unit). The percentage of the ratio of the difference between the vehicle's steady speed and the full load steady speed to the ratio of the calibrated speed. The maximum steady-state regulation rate is: (set speed - maximum speed drop value) / set speed. [0003] When the user expects to change the set speed and the rate of adjustment, the existing control and adjustment methods cannot meet the needs of the user to freely select the speed and rate of adjustment. Contents of the invention [0004] The present invention propos...
