Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described:

[0018] figure 1 A start-stop control system of a car is shown, including an EMS module (ie, an engine control module) and a camera; the camera is installed at the front windshield of the car, and is connected with the EMS module through a CAN bus; the EMS module is connected with the engine of the car; To obtain the traffic road condition information, and transmit it to the EMS module through the CAN bus, the traffic road condition information in the present embodiment is mainly a traffic light signal; the EMS module is used to receive the traffic road condition information, and control the engine operation according to the traffic road condition information; the traffic light signal collected by the camera signal; after recognizing that the road traffic lights ahead are in the red and green state, the EMS module controls the engine to enter the automatic shutdown state ac...

Abstract

The invention relates to a start and stop control system and a start and stop control method of an automobile. The control system comprises an EMS module and a camera, wherein the camera is connected with the EMS module via a CAN bus; the EMS module is connected with the engine of the automobile; the camera is used for acquiring traffic road condition information, and transmitting the information to the EMS module via the CAN bus; and the EMS module is used for receiving traffic road condition information, and controlling the engine to operate according to the traffic road condition information. According to the scheme of the system and the method provided by the invention, the camera is added in an existing parking strategy, the forward traffic road condition can be recognized more early and the engine enters a stop state, and thus oil saving and consumption reduction efficiency is improved; the control strategy is changed, automatic stop and start management is optimized, cost caused by addition of the control module is avoided, and the driving requirement of a driver is met in time; before an operation action of the driver is triggered, the system automatically judges the road condition and automatically executes stop and start, and thus intelligence and high-tech feeling of the whole automobile are embodied.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an automobile start-stop control system and a control method. Background technique [0002] With the increasingly stringent requirements of national regulations on fuel consumption, engine start-stop technology has become a new measure to save fuel and reduce consumption. The economic effect of saving fuel is more significant. For example, in the long process of waiting for a red light or traffic jam at a busy intersection, the whole vehicle will judge whether the current state can enter the automatic shutdown state according to the driver's operation, so as to achieve the purpose of saving fuel consumption and reducing emissions; The premise of the stop state is that the driver needs to step on the brake pedal (automatic transmission model) to perform the service brake and finally bring the whole vehicle to a standstill, then the system will make a logica...
