Abstract

The invention discloses a vehicle alarm method, a vehicle-mounted device, a computer storage medium and a system. The vehicle alarm method is applied to a vehicle-mounted device, and the vehicle-mounted device includes an on-chip system, a micro control unit, a switch, a digital signal processing chip, and a power amplifier ; Wherein, the system-on-chip includes a large core, a micro-kernel, a first serial port and a second serial port, and the method includes: the micro-kernel starts when detecting that the control system running on the large core crashes, and passes the The micro control unit acquires vehicle state information in real time; when the microkernel determines that the vehicle fails according to the vehicle state information, it sends an alarm audio signal to the power amplifier through the digital signal processing chip, so that the power amplifier passes through the speaker in the vehicle Play the alarm audio signal. The vehicle alarm method, vehicle-mounted equipment, computer storage medium and system provided by the present invention can improve driving safety and user experience.

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] In the process of using the car, due to factors such as improper operation by the driver or a long service life, the car usually has various failures, or some parameters of the car are approaching or exceeding the threshold, and the corresponding failure needs to be solved in time. In order to remind the driver to pay attention to and / Or solve these faults in time to avoid affecting the driving safety, and the car usually emits an alarm sound to remind the driver. In the related art in the prior art, an in-vehicle speaker is usually driven by a digital processing chip and a power amplifier in an in-vehicle device such as an in-vehicle device or a smart cockpit to emit an alarm sound. However, the functions of in-vehicle equipment are complex and frequently used, and it is i...
