Embodiment Construction

[0009] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] like figure 1 As shown, the vehicle load management control system includes battery sensor (1-1), rear defrosting (1-2), body controller (1-3), instrument (1-4), air conditioning controller (1-5) , DVD (1-6), lighting controller (1-7), seat controller (1-8), EFI controller (1-9), blower (1-10), speaker (1-11) , Interior light (1-12), seat heating (1-13), seat ventilation (1-14), seat massage (1-15).

[0011] The body controller (1-3) collects the signal of the EFI controller (1-9) through the CAN bus, and the signal of the battery sensor (1-1) through the LIN bus. After logical processing, the calculated power management level is passed through the CAN bus. The bus is sent to the air conditioning controller (1-5), DVD (1-6), lighting controller (1-7), seat controller (1-8); the body...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an automobile load management control system, which can be used to prevent the automobile from failing to start due to excessive power loss of the storage battery. Background technique [0002] With the development of electronic and electrical technology, modern automobiles use more and more electrical equipment, and the load current consumption of vehicle electrical appliances is increasing. If the user does not use it properly, such as turning on the blower, seat heating and other electrical equipment after the engine stops, the battery will be in a continuous discharge state. For vehicles without load management, the electrical appliances will stop working due to insufficient power supply voltage only after the battery power is extremely low. At this time, the battery can no longer provide enough current for the vehicle to start, causing the vehicle to fail to st...
