Embodiment Construction

[0022] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and implementation methods.

[0023] In automatic transmission models, for the protection of the transmission chain and the safety of the vehicle body (to prevent the starter from working when the transmission chain is not disconnected), the gearbox control unit needs to independently control the starter; in the start-stop function, the engine control unit acts as The realization unit of the start-stop function also needs to be able to complete the work of controlling the starter. In order to coordinate the gearbox control unit and the engine control unit, the present invention designs a new start control device, such as figure 2 It is a structural schematic diagram of the start-up control device according to the embodiment o...

Abstract

The invention discloses a vehicle start control device. The device is used for an automatic transmission vehicle and comprises a storage battery, an ignition device, an engine control unit, a transmission control unit, a start relay, a starting engine, a first controller and a second controller. The engine control unit is connected with the transmission control unit through a CAN bus. A coil of the start relay is connected between the output end of the second controller and a ground. The engine control unit is connected with the control end of the first controller through an I / O port so as to control on-off of the first controller. The engine control unit is connected with the output end of the second controller through another I / O port so as to detect the output state of the output end of the second controller. The transmission control unit is connected with the control end of the second controller through one I / O port so as to control on-off of the second controller. By means of the vehicle start control device, the safety of the automatic transmission vehicle in the starting control process is improved, and the error start rate of the starting engine is lowered.

Description

technical field [0001] The invention relates to the technical field of vehicle start control, in particular to a vehicle start control device. Background technique [0002] With the tightening of automobile emission and fuel-saving regulations, how to reduce the fuel consumption level of automobiles has become a key issue for OEMs. Among many fuel-saving technologies, the engine start-stop technology is widely adopted by various OEMs because of its low implementation cost and the ability to effectively reduce engine fuel consumption in urban working conditions. [0003] In automatic transmission models, the existing launch control devices such as figure 1 As shown, the specific implementation process of start-up control is: after the engine control unit 2' and the transmission control unit 5' receive the ignition signal sent by the ignition device 1', they are powered on to complete the self-check, and the transmission control unit 5' detects the transmission chain state, ...
