Embodiment Construction

[0023] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0024] Such as figure 1 As shown, an instantaneous power optimization control method is provided, including the following steps:

[0025] (1) Receive the instant power optimization start command, function initialization state, make the cumulative activation time T1=0, exit waiting time T2=0, the initialization initial value can also be preset as other initial values ​​according to needs;

[0026] (2) The controller receives the accelerator pedal signal, the gear position signal of the gearbox, and the engine state monitoring sensor signal, and judges whether the instantaneous power optimization function activation condition is satisfied according to the above signals, and if so, proceeds to step (3), otherwise continues to monitor and judge, And the opening condition is cyclically checked and judged within the preset time;

[0027] (3) Enter the function act...

Abstract

The invention discloses an instantaneous dynamic optimization control method. The instantaneous dynamic optimization control method comprises the following steps of receiving an accelerator pedal signal, a gearbox gear signal, and an engine state monitoring sensor signal by a controller; judging whether the opening condition for an instantaneous dynamic optimization function is met or not according to the signals; if yes, entering a function activation state, releasing a power output external characteristic limiting value of an engine to a preset safety margin, and releasing an external characteristic torque limit, so that the responsiveness of a transient output requirement of the engine is improved; else, exiting the function activation state, and restoring the limited state of power output of the engine, so that the safety is guaranteed; and when the function is under a state of exiting activation, and after the opening condition for the instantaneous dynamic optimization function is met again, re-activating the instantaneous function to meet use requirements of a user. The instantaneous dynamic optimization control method disclosed by the invention is low in realizing cost, high in reliability and wide in application scope, and can furthest tap the existing potential of the power output of the engine under the premise that the service life and the discharging conditions of the engine are not influenced, so that the instantaneous power output requirements of the user are met.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to an instantaneous power optimization control method. Background technique [0002] Driving an automatic transmission car has a habit that needs to be developed, that is, to learn to use the accelerator to control the gear of the gearbox. With different accelerator pedals, the gears selected by the gearbox are different at the same vehicle speed. For example, at 60km / h, the optional gears of the automatic transmission are 2nd, 3rd or 4th, depending on how hard the driver steps on the accelerator. During normal driving, the gearbox generally shifts to the highest gear very quickly. This setting is not only for fuel saving, but also for smoother driving. Only when the accelerator pedal is heavy, the gearbox will delay upshifts to obtain more power. [0003] The working principle of the automatic transmission is: pay attention to fuel economy at ordinary ...
