Embodiment Construction

[0086] The embodiment of the present invention is described below by way of example, what this embodiment uses is the engine electronic controller for six-cylinder heavy truck.

[0087] Such as figure 1 As shown, an adjustable multi-condition power distribution method includes a program running on the vehicle-mounted computer (engine electronic controller), and the specific implementation steps of the program are as follows:

[0088] Step 1: Define the required working conditions; the functions realized by this working condition must be provided by the power output of the automobile engine; and can be converted into expectations for acceleration or deceleration of the engine speed; there are four working conditions in this embodiment: idle working condition, engine braking condition ERC, cruise control condition CC, torque-based acceleration control condition ABT. , at the same time, each constant parameter is determined according to the engine characteristics: torque integra...

Abstract

The invention discloses an adjustable multi-working-condition power distribution method, which improves the traditional vehicle-mounted power control method, improves the traditional comprehensive torque control method, and decomposes the torque control into working-condition expectations Decomposition, comprehensive optimization and torque control are three links. In the link of working condition expectation decomposition, the expected value of the power required by the working condition for the angular acceleration of the engine is calculated separately for each working condition, and then in the link of optimization, it is classified and judged according to the priority and expected value. The optimal value of each classification is integrated as the input signal of the subsequent control, and finally the final expected torque is calculated in the torque control link. The method decouples the participating working conditions, and for different vehicle models, the participating working conditions can be flexibly increased or decreased, which effectively improves the versatility, reliability and portability of the multi-working condition vehicle power control method.

Description

technical field [0001] The invention belongs to the technical field of electric control engine power control. Specifically, it is a power distribution and control method for an electronically controlled vehicle engine under complex working conditions. Background technique [0002] At present, electronically controlled fuel injection technology has been widely used in the automotive field. This technology uses ECU as the main control unit, and realizes precise control of engine power through software control of electronically controlled actuators. Electronically controlled fuel injection usually divides the entire fuel injection process into signal input, torque control, fuel injection quantity control, fuel injection output and other links. Among them, torque control is the core of realizing electronically controlled fuel injection technology, and its effectiveness directly affects the power and economy of the engine. In this link, the external environment signal and the e...
