An Engine Electronic Injection Control System Based on Torque Control

Abstract

The invention discloses an engine electronic fuel injection control system based on torque control, and aims to provide a control system which can output stronger power, saves fuel consumption better, is more beneficial for emission of engine tail gas pollutants, is more stable in engine operation, and is more comfortable. The engine electronic fuel injection control system comprises an engine control system, various operation parameters of a vehicle and an engine are measured by various sensors mounted on the vehicle and the engine, a torque relation is established through adopting the torque as an intermediate variable through the set control process and data, a request is made to the system in a torque request form, a torque coordination processing module is used for coordinating, a torque centralized output module is used for outputting the torque, the engine is in operation in an optimized state through controlling an ignition system, an oil supply system and an air distribution system, and the output of the engine output torque is realized. The system is mainly used for vehicle control systems.

Description

technical field [0001] The invention relates to an engine control system, in particular, an engine electronic injection control system based on torque control. Background technique [0002] At present, most cars still use the EFI control system based on throttle control. The EFI control system based on throttle control adopts the method of throttle cable. The traditional cable throttle is connected to the accelerator pedal at one end of the steel wire and the throttle at the other end. Connected, it is a mechanical structure, and its transmission ratio is 1:1, that is to say, how much we pedal, the opening angle of the throttle valve is the same, but in many cases, the throttle valve should not open such a large angle, Therefore, the opening angle of the throttle valve at this time is not necessarily the most scientific, and the response is quick. Although this method is very direct, its control accuracy is very poor, and it is difficult to accurately control fuel consumptio...

Problems solved by technology

Moreover, in the matching process (that is, the process in which the electronic control system platform and peripheral devices cooperate with the specific engine work), there is a strong dependence between the matching data of different subsystems, and each working point in the matching process must be Multiple measurements and repeated calibration make the calibration work cumbersome

[0004] In the existing technology, there is no engine control system based on torque control that integrates multiple functions, such as variable valve timing VVT control, variable intake manifold control, exhaust gas turbocharging control, exhaust gas recirculation As well as the functions of the latest engine control technology such as secondary air intake control, if the corresponding manufacturer needs several of these functions to be placed on one vehicle, such as for manufacturers of V-type engines that want to increase engine power and torque, variable Intake manifold control and exhaust gas turbocharging control, for engine manufacturers who want to increase power and torque, but also want to save fuel and lower emissions, may need exhaust gas turbocharging, exhaust gas recirculation control and secondary air intake, etc. As customer needs change and emission regulations become more and more stringent, OEMs need faster time to market. It is an engine management system manufacturer to establish a multi-functional and scalable engine control system to meet the needs of the rapidly changing market. The problems faced, need to re-develop a new engine control system, which is bound to supercharge the development cycle of the engine control system and increase the development cost
