Automobile transportation mode control device and method

Abstract

The invention provides an automobile transportation mode control device, which comprises an automobile body controller, a transportation mode switch, a relay, an instrument, and controllers with static current, such as an air conditioner controller and a lamp controller. The transportation mode switch totally has two states including a switch switch-off state and a switch switch-on state. When the transportation mode switch is switched on, the automobile body controller detects a high level, the current mode is judged to be a common mode, when the output end of the control relay is in a low level state, the relay does not suck, and the whole automobile normally works; when the transportation mode switch is switched off, the automobile body controller cannot detect the high level, the current mode is judged to be a transportation mode, if the whole automobile network is in a wakening state, or a key is in a non-off gear, the automobile body controller controls to suck the relay, and the whole automobile normally works; after the whole automobile network is in a dormancy state, or the whole automobile is in an off gear for more than 10s, the automobile body controller controls to output a low level, the relay is switched off, and the static current consumption of the whole automobile is reduced. The control device provided by the invention has the advantages that the active management on a vehicle-mounted controller in an automobile transportation process can be realized, the static current consumption of the automobile in the transportation process is reduced, the storage battery discharging quantity is obviously reduced, and the starting failure risk after the automobile achieves a transportation destination is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to the control of automobile transportation modes. Background technique [0002] After the vehicle is produced in the vehicle factory, it needs to be transported to various cities. The entire transportation process can take as long as one month. After some vehicles arrive at the destination, they may fail to start due to insufficient battery power. At present, various OEMs mainly avoid this problem by pulling out the insurance, breaking the battery pile head, and increasing the transportation mode. Because unplugging the fuse and breaking the battery pile head will damage the parts, the operation is cumbersome, and the consistency of manual operation cannot be guaranteed. At present, most OEMs have begun to study and use the transportation mode. The announcement number CN101700769A uses the diagnostic instrument to configure the transport mode and normal mode. After the...

Since this method can only reduce the quiescent current of the communication controller, the effect of reducing the quiescent current of the whole vehicle is not obvious, and it takes a long time to configure it with a diagnostic instrument
