Embodiment Construction

[0034] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] In this embodiment, the device for realizing the automatic start and stop of the engine includes an OBD data interface module (OBDM), a central processing module (MCU), two wireless measurement and control relays and an automobile CAN bus monitoring module (respectively the first one for realizing the automatic start function). The wireless measurement and control relay J1, the second wireless measurement and control relay J2 for realizing the automatic flameout function, and the automobile CAN bus monitoring module for realizing the braking action detection function). The OBD data interface module and the vehicle CAN bus monitoring module are connected with the central processing module, and the OBD data is collected in real time and sent to the central processing module for processing. The two wireless measurement and con...

Abstract

The invention discloses a device and a method for realizing automatic starting and stopping of a vehicle engine. A vehicle has an automatic starting and stopping function. The device comprises a second wireless measurement and control relay which can realize automatic flameout function and a vehicle CAN bus monitoring module which can realize a braking action detection function; and when it is detected that the vehicle is in a braking state and is stopped, and the automatic starting and stopping function is not switched off, the second wireless measurement and control relay is controlled to be switched off, so that the engine flameouts. By combining utilizing the wireless measurement and control relay with OBD data, the automatic starting and stopping function of the vehicle engine is realized.

Description

technical field [0001] The present application relates to a device and method for realizing automatic start and stop of an engine. Background technique [0002] The automatic engine start-stop function is a newly emerging technology for saving fuel and reducing emissions. Start / Stop is an anti-idling technology that saves fuel by shutting off the engine when the vehicle is stopped. The automaker claims that Start / Stop increases fuel efficiency by 10%. The start / stop function is commonly found on newer models with higher configurations. But for a large number of stock models currently on the market, as well as models with lower configurations, this function does not exist. At present, there are already OBD start-stop products in the automobile market, such as VOYO in the United States. But this product relies heavily on OBD data. Especially the "brake switch" signal. It must correspond to a vehicle that contains two brake switches (brake switch A, brake switch B) in the...
