Abstract

The invention discloses a vehicle alarm method, vehicle-mounted equipment, a computer storage medium and a system. The vehicle alarm method is applied to the vehicle-mounted equipment, and the vehicle-mounted equipment comprises a system-on-chip, a micro-control unit, a switch, a digital signal processing chip and a power amplifier; the system-on-chip comprises a large core, a micro-core, a firstserial port and a second serial port. The method comprises the steps that the micro-core is started when detecting that a control system running on the large core breaks down, and vehicle state information is obtained in real time through a micro-control unit; and when the microkernel determines that the vehicle breaks down according to the vehicle state information, an alarm audio signal is sentto a power amplifier through the digital signal processing chip, so that the power amplifier plays the alarm audio signal through a loudspeaker in the vehicle. According to the vehicle alarm method and system, the vehicle-mounted equipment and the computer storage medium, the driving safety can be improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of alarm, in particular to a vehicle alarm method, vehicle-mounted equipment, computer storage medium and system. Background technique [0002] During the use of the car, due to factors such as improper operation by the driver or a long service life, the car usually has various faults, or some parameters of the car are approaching or exceeding the threshold and need to solve the corresponding faults in time. In order to remind the driver to pay attention and / Or solve these failures in time to avoid affecting driving safety, and the car will usually send out an alarm sound to prompt the driver. In the prior related art, it is usually through the digital processing chip and the power amplifier in the car equipment such as the car machine or the smart cockpit to drive the speaker in the car to send out the alarm sound. However, the vehicle-mounted equipment has complex functions and is frequently used. In actual opera...
