Abstract

The invention is applied to the technical field of automobile control and provides an automobile auxiliary control device based on rail pressure signal and air entering pressure signal comparison. Aninput end of a first signal comparison unit is connected with a signal output end of an air entering pressure sensor. An output end of the first signal comparison unit is connected with an automobileECU. An input end of a second signal comparison unit is connected with a signal output end of a rail pressure sensor. An output end of the second signal comparison unit is connected with the automobile ECU. By means of the device, an automobile can make corresponding change according to different road conditions, and the highest potential of an engine is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an automobile auxiliary control device based on the comparison between a rail pressure signal and an intake pressure signal. Background technique [0002] ECU (Electronic Control Unit) refers to the electronic control unit, also known as the driving computer, which is installed inside the car and is generally used to control the fuel injection amount, the mixture ratio, etc., and is composed of a microprocessor, memory, input / output interface, module It is composed of large-scale integrated circuits such as converters, shaping and driving. [0003] The existing automobile rail pressure sensor converts the detected pressure into an electrical signal and transmits it to the engine ECU, and the automobile intake pressure sensor converts the detected pressure into an electrical signal and transmits it to the automobile ECU. The signal corrects the speed of the...
