Embodiment Construction

[0062] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] refer to figure 1 , a method for controlling the temperature of a vehicle-mounted system according to an embodiment of the present invention, comprising:

[0064] S1: Determine whether the temperature value of the CPU of the vehicle system exceeds a first preset temperature within a specified period of time.

[0065] The specified duration of this step is, for example, 6S, 8S, etc., and the first preset temperature is 125° C., which is a temperature threshold point that affects the normal operation of the vehicle system.

[0066] S2: If yes, reduce the operating load of the CPU of the vehicle system.

[0067] This step reduces the operating load of the vehicle-mounted system CPU by reducing the operating load of the multi-core CPU. For example, by turning off the auxiliary three-core CPU of the quad-core CPU,...

Abstract

The invention discloses a method and a device for controlling vehicle-mounted system temperature. The method for controlling the vehicle-mounted system temperature comprises the steps that whether thetemperature value of a vehicle-mounted system CPU within the specific period of time exceeds the first preset temperature is judged; and if the judgment result is yes, the operation load of the vehicle-mounted system CPU is reduced. The temperature change of the vehicle-mounted system CPU in the operation process is monitored, and the method of timely turning off certain functions in use or reducing the operation load of the CPU is used so that the heat produced by operation can be reduced, the temperature value of the whole vehicle-mounted system can be reduced, the vehicle-mounted system can be protected, and the probability of safety hidden trouble caused by instability and hardware damage of the vehicle-mounted system because of excessively high temperature can be reduced.

Description

technical field [0001] The invention relates to the field of vehicle-mounted systems, in particular to a method and device for controlling the temperature of the vehicle-mounted system. Background technique [0002] With the development of modern automobile industry and electronic technology, electronic systems such as vehicle navigation, communication, multimedia audio-visual entertainment can be networked through network technology to form a powerful comprehensive vehicle system. The future vehicle-mounted system will develop towards an integrated, intelligent, and fully graphical information platform. The existing in-vehicle system can meet the needs of users who run multiple programs at the same time, but it brings great challenges to the CPU operation of the in-vehicle system, and the in-vehicle system will run due to the CPU, WIFI, 4G and other functional modules of the in-vehicle system. A lot of heat will be generated, and the temperature will be too high, which wil...
