Problems solved by technology

At present, the starting method of the multimedia system is to start the multimedia system when the ignition switch of the vehicle is in the ACC gear, which causes the user to wait for the loading time of the multimedia operating system when using it, which makes the user wait too long and cannot satisfy the user. The need for real-time operation
However, if the multimedia system is used as a constant power module, that is, a constant power supply module, it will affect the low power consumption of the vehicle when the vehicle is dormant.

Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The present invention provides a method for starting the vehicle multimedia system of an embodiment, such as figure 1 As shown, the method includes the following steps:

[0050] Step S1, obtain the current state of the ignition switch, and proceed to step S2;

[0051] Step S2, judging whether the current state of the ignition switch is in the OFF gear, when the current state of the ignition switch is in the OFF gear, enter step S3, and when the current state of the ignition switch is in a non-OFF gear, enter step S4;

[0052] Step S3, detecting the state of the ...

Abstract

The invention provides a vehicle-mounted multimedia system starting method, a starting device and a vehicle body control system. The method comprises the following steps of acquiring the current state of an ignition switch, judging whether the current state of the ignition switch is in the OFF file, detecting the state of the overall vehicle when the current state of the ignition switch is in the OFF file, and outputting starting signals of the vehicle-mounted multimedia system when the current state of the ignition switch is not in the OFF file or the state of the overall vehicle is in a non lower power consumption state and in a non anti-theft state. By using the method, the starting wait time is reduced, the low power consumption of the overall vehicle is not influenced, the user experience is enhanced and use of the user is facilitated.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a starting method, a starting device and a vehicle body control system of a vehicle multimedia system. Background technique [0002] In the prior art, the in-vehicle multimedia system starts when the ignition switch is in the ACC gear, that is, the MCU of the in-vehicle multimedia system is not powered under normal power, and the MCU is powered only when the ACC power is effective. Since the in-vehicle multimedia system has its own operating system, it takes a certain amount of time from loading the operating system to when the multimedia system is started until the user can operate it. At present, the starting method of the multimedia system is to start the multimedia system when the ignition switch of the vehicle is in the ACC gear, which causes the user to wait for the loading time of the multimedia operating system when using it, which makes the user wait too long and ca...
