Embodiment 1

[0044] figure 1 It is a structural diagram of an automobile combination switch system provided in the embodiment of this application.

[0045] Such as figure 1 As shown, the automobile combination switch system provided in this embodiment includes a handle switch 10 , a LIN (Local Interconnect Network) interface 30 , a controller 20 , and a CAN (Controller Area Network) interface 40 . The controller 20 is connected with the handle switch 10 , the LIN interface 30 and the CAN interface 40 respectively.

[0046] The handle switch 10 is arranged under the steering wheel of the automobile, and includes a plurality of switches, such as a light switch 11, a steering switch 12, and a front and rear wiper switch 13. The handle switch 10 of some types of automobiles is also provided with a cruise switch 14. The handle switch 10 is used to receive a driver's control command, and output a control signal according to the control command.

[0047] The LIN interface 30 is used to connect...

Embodiment 2

[0059] image 3 It is a structural diagram of an automobile combination switch system provided by another embodiment of the present application.

[0060] Such as image 3 As shown, the automobile combination switch system provided in this embodiment is based on the automobile combination switch system provided in the previous embodiment, and a power management chip 60 is added, and the power management chip 60 is connected with the controller 20 for providing 20 outputs the voltage required by the controller 20 for normal operation.

Embodiment 3

[0062] Figure 4 A structure diagram of an automobile combination switch system provided by another embodiment of the present application.

[0063] Such as Figure 4 As shown, the automobile combination switch system provided in this embodiment is based on the automobile combination switch provided in the previous embodiment, and a voltage monitoring unit 70 is added, and the voltage monitoring unit 70 is connected to the controller 20 .

[0064] The voltage monitoring unit 20 is used to monitor the power supply of the automobile, such as the voltage of the storage battery, and output the voltage monitoring value to the controller 20. The controller 20 calculates the voltage monitoring value, and outputs an alarm signal in time when undervoltage occurs. To remind the driver to overhaul or maintain in time.

Abstract

The invention provides an automobile combined switch system, which comprises a controller, a mechanical switch, an LIN (Local Interconnect Network) interface and a CAN (Controller Area Network) interface, wherein the controller is connected with the mechanical switch, the LIN interface and the CAN interface respectively; the controller is used for receiving driving signals from the mechanical switch, also can be connected with a plurality of extension switches through the LIN interface, and is used for receiving extension control signals through the extension switches, generating driving signals according to the driving signals and the extension signals, and outputting the driving signals to a BCM (Body Control Module) of an automobile through the CAN interface to control each sub-system of the automobile. The LIN can be connected with the plurality of extension switches, so that the extendibility of the automobile combined switch system is high, and the problems of single function and poor extendibility of the conventional automobile combined switch can be well solved.

Description

technical field [0001] The present application relates to the technical field of automobiles, and more specifically, relates to an automobile combination switch system. Background technique [0002] The car combination switch is used to control the lights and wipers of the car through the left and right handles on both sides of the steering wheel. The function is relatively single and the scalability is poor. Contents of the invention [0003] In view of this, the present application provides an automobile combination switch system, which is used to solve the problems of relatively single function and poor expandability of the existing automobile combination switch. [0004] In order to achieve the above purpose, the proposed scheme is as follows: [0005] A combination switch system for an automobile, comprising: [0006] The handle switch is used to receive a control command and output a control signal according to the control command; [0007] A local interconnection...
