Detailed Description
The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.
To reducing quiescent current, the main method is in time dormancy and optimal control logic, reduce the quiescent current that controller work produced through logic control, the vehicle does not start for a long time under the transport condition among the prior art mainly, this application discerns control through logic control, thereby reduce quiescent current's technical scheme, thereby can control under the longer state of time such as vehicle transportation and realize closing of controller and reduce quiescent current, the reliable operation of vehicle has been guaranteed, avoid quiescent current to the damage of vehicle battery, avoid the insufficient voltage, concrete scheme includes:
as shown in fig. 1, a control system for reducing the quiescent current of an automobile comprises a BCM, a transportation state detection unit, an ignition state detection module and an on-board controller, wherein the transportation state detection unit is used for detecting whether a vehicle is in a transportation state, and the output end of the transportation state detection unit is connected with the BCM; the ignition state detection module is used for detecting the ignition state information of the vehicle, and the output end of the ignition state detection module is connected with the input end of the BCM; the output end of the BCM is connected with an on-board controller, and the BCM controls the on and off of the on-board controller according to the detected transportation state of the vehicle and the ignition state information of the vehicle. When the vehicle is detected to be in a transportation state and the ignition state of the vehicle is OFF, the BCM outputs a signal to control the vehicle-mounted controller to be turned OFF, so that quiescent current generated by the operation of various electrical appliances, controllers and the like of the vehicle in the transportation state is avoided. The control of the shutdown of the system comprises modes of dormancy or direct power-off and the like.
The vehicle-mounted controller is a control unit of each vehicle electrical appliance connected with and controlled or driven by the BCM on the vehicle, and comprises a vehicle window controller, a vehicle door controller, an instrument, a CAN and other vehicle-mounted controllers, when the whole vehicle is in an OFF gear and is still in a working or semi-working state, the static current CAN still be generated, and when the whole vehicle is in a transportation state, the vehicle CAN not be used for a long time, so that each vehicle-mounted controller needs to be closed, and the generation of the static current is reduced. The BCM outputs a control instruction to control the BCM to be closed, so that the generation of static current is reduced.
In the present application, the transportation state detection unit mainly detects whether the vehicle is in a transportation state, because the transportation state is generally in a sales or transportation state of the vehicle, and it takes several days to transport the vehicle by land and several tens of days or more to transport the vehicle by sea, and therefore, when the vehicle is identified to be in the transportation state, control must be performed to reduce the quiescent current. The present application provides two ways to achieve detection of transport state:
1. the transportation state detection unit comprises a position detection module, a data processing module and a timer, wherein the input end of the data processing module is respectively connected with the data processing module, the timer and the ignition state detection unit, and the output end of the data processing module is connected with the BCM. The position detection module can be realized by a positioning chip such as a GPS (global positioning system) and the like, and can be realized by an in-vehicle integration mode, for example, an integrated GPS is generally arranged in a TBOX (tunnel boring machine), the data processing module mainly analyzes and judges timing data, ignition data and GPS position data of a timer, and when the GPS data are changed consistently, the timing reaches set time and the ignition state is OFF, the transportation state is judged, so that the timing time is only required to be set. The data processing module can be implemented by a processing chip with data processing and control functions, such as a microcontroller like a single chip microcomputer or a PLC, which outputs a transport state signal to the BCM or integrates the data processing and judging function of the data processing module in the BCM.
2. The method is realized by adopting a transport state write-in terminal, wherein the write-in terminal can be a diagnostic instrument, a control instruction is written into a vehicle in an OBD diagnosis port mode through a diagnostic protocol, then the control instruction is transmitted to a BCM (binary coded decimal) through a can network and the like of the vehicle, the BCM can enter a transport state mode after receiving the control instruction, and an on-board controller connected with the BCM is controlled to be closed.
The BCM is electrically connected with the KL15 and is waken by the KL15 in an electric driving mode, when the vehicle is in an ON gear, the KL15 in an electric driving mode can waken the BCM to start, and therefore the BCM starts each vehicle-mounted controller, and the vehicle returns to be normal. Setting a marine mode: the BCM is set by the diagnostic instrument to enter marine mode, where when the ignition switch is in the OFF gear, the BCM will turn OFF all outputs and can only be awakened by 15-volt.
In a preferred embodiment, in order to avoid increase in quiescent current or stress during normal vehicle use, all vehicle lights may be turned off after the vehicle is armed, except during transport, to reduce quiescent current. The method specifically comprises the following steps: BCM is connected with the signal detection module of seting up defences for detect and receive the signal of seting up defences, BCM's output is connected to car light control switch, and vehicle control switch concatenates between battery and car light. Wherein the signal detection module of seting up defences can directly acquire the signal of seting up defences of key through on-vehicle low frequency signal radio frequency signal antenna, and then closes the car light according to the signal of seting up defences, and car light control switch adopts the height to drive the chip, uses the height to drive the chip drive little load with electrical apparatus, for example control indicator, position lamp, indoor dome lamp etc. not only can reduce the consumption, can also realize transshipping overtemperature prote, realize the diagnostic function. Common high-driver chips include VND7E025AJTR, and multi-path low-driver chips include ST 2-channel driver chips VNLD5300 TR-E. Setting a power saving function: after the BCM is successfully defensed, all light output is cut off, and the storage battery is prevented from being short of power due to forgetting to turn off a light switch;
it is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
