The invention discloses an automobile
load management control system. The
system adopts the scheme that an automobile body control device is connected with a battery sensor through an LIN
bus, is connected with a meter, a DVD, an air conditioner control device, a
light control device and a seat control device through a
CAN bus, and is connected with a rear
defrosting device through a
hatching line. The automobile body control device collects the engine state
signal and the battery sensor
signal for calculating and logic judgment, sends the calculated power
supply management level to the DVD, the air conditioner control device, the
light control device and the seat control device through the
CAN bus to control sound equipment, a blower, an indoor light, a seat heating component, a seat massaging component and a seat ventilation component to work at the corresponding levels, and judges whether the starting of the rear defrost device is allowed or not according to the power
supply management level and the generator state; the automobile body control device judges the display information required to be displayed by the meter currently according to the engine state and the battery sensor information, and sends the judgment result to the meter through the
CAN bus. According to the invention, aiming at the use condition of a user, a load operating state is initiative adjusted, and the electric quantity of an accumulator is controlled to be within a better range, so that the situation that an automobile is unable to start due to the overdischarging of the accumulator is avoided.
