Vehicle and front cabin intelligent electric appliance box thereof

Abstract

The invention discloses a vehicle and a front cabin intelligent electric appliance box thereof. The front cabin intelligent electric appliance box comprises a shell, a CAN communication unit, a driving module and a control unit, wherein the CAN communication unit is used for conducting CAN communication with a vehicle body controller; the driving module is used for driving a plurality of loads arranged in a front cabin of the vehicle and diagnosing working conditions of the multiple loads so as to obtain fault information of each load; and the control unit is arranged in the shell and used for receiving a control command sent by the vehicle body controller through the CAN communication unit, controlling the multiple loads through the driving module according to the control command, collecting the fault information of each load, and reporting the fault information of each load to the vehicle body controller through the CAN communication unit. Thus, hardwired connection with the vehicle body controller can be effectively reduced, cable cost is lowered, and reliability is improved; and besides, the working conditions of each load can be diagnosed, the fault information is reported to the vehicle body controller, and thus a driver is reminded.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a smart electrical box in the front cabin of a vehicle and a vehicle with the same. Background technique [0002] Usually, in a car, the front compartment electrical box is mainly responsible for the control of low-voltage electrical components such as external lights, horns, wipers, fans, water pumps, and vacuum pumps. However, the front compartment electrical box itself does not have control functions, and its control commands come from the body. controller. [0003] Such as figure 1 As shown, generally the front cabin electrical box is arranged in the front cabin, and the body controller is arranged in the cab, and the front cabin electrical box and the body controller are connected by multiple hard wires, so that the front cabin electrical box can be controlled according to The command controls the corresponding low-voltage electrical components. However, since the con...

AI Technical Summary

Problems solved by technology

However, since the connection wires between the body controller and the front cabin electrical box need to pass through the partition between the cab and the front engine room, and there are many connection wires, not only the cable cost is high, but also the reliability is low, and at the same time, it is impossible to control the low-voltage electrical components.
