Problems solved by technology

However, small-displacement engines generally have poor low-speed torque, and the effective output power of the engine is not high at low speeds. The poor output power of the lower engine leads to poor acceleration performance of the whole vehicle, which has become a bottleneck affecting the driving pleasure of cars using small displacement engines

Embodiment Construction

[0019] Throttle position sensor 1 as figure 1 , 2 As shown, a resistive film 11 is provided inside, and the throttle opening signal contact 12 and the idle speed signal contact 13 are located in the resistive film 11, and the throttle opening signal use movable contact 12 and the idle speed signal use movable contact The point 13 slides on the resistance film 11, detects the opening degree of the throttle valve and converts the opening degree signal into a voltage signal, and transmits it to the controller 1 body. Open the resistive film 11 and peripheral parts.

[0020] see image 3 , 4 It can be seen that a constant voltage of 5V is always applied to the VC terminal of the throttle position sensor 1, and the movable contact 12 for the throttle opening signal slides on the resistance film 11 according to the throttle opening, and there will be a voltage on the VTA terminal. Voltage output proportional to throttle opening. When the throttle valve is fully closed, the mova...

Abstract

The invention discloses an engine load control system. A return signal of a throttle position sensor is detected, related signals such as vehicle speed just at that moment, rotating speed of an engine, an opening angle of a throttle and change rate of the opening angle are analyzed, whether the engine is in a low-rotating-speed heavy load working condition is judged intelligently, and whether a high power load such as an air-conditioner compressor is required to be cut off in time is judged intelligently. Thus the aims of increasing effective output power of the engine in short time, causing the engine to enter into a better working condition as soon as possible, saving energy, reducing emission and improving operation comfort of a low-emission vehicle are achieved.

Description

technical field [0001] The invention relates to an automobile control system; more specifically, it relates to an intelligent control system for timely cutting off unnecessary loads in the automobile. Background technique [0002] With the rise of oil prices and the concept of energy saving and environmental protection gradually becoming popular among the people, cars with small displacement engines are gradually accepted and loved by the public with relatively low operating and maintenance costs. However, small-displacement engines generally have poor low-speed torque, and the effective output power of the engine is not high at low speeds. The poor output power of the lower engine leads to poor acceleration performance of the whole vehicle, which has become a bottleneck affecting the driving pleasure of cars using small displacement engines. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a control system that ...
