Problems solved by technology

[0006] 1. Because the voice navigation also includes vehicle driving direction and road condition information, it is often impossible to intercept the speed limit information in time
2. It has an impact on hearing-impaired drivers, noisy environments, and voice navigation broadcasts in listening to songs, radio and other modes
3. It is not possible to give an alarm to overspeed all the time

Embodiment Construction

[0026] The overspeed alarm method based on automobile instrument of the present invention, as figure 1 , figure 2 As shown, using a mechanical or liquid crystal instrument for alarm display includes the following steps:

[0027] S1. Obtain the speed limit information of the current road section in real time on the CAN network of the vehicle;

[0028] S2. Compare with the current actual vehicle speed to determine the current state of overspeeding or not;

[0029] S3. According to whether overspeed or not, control the pointer color of the mechanical or liquid crystal instrument to display the corresponding alarm;

[0030] S4. Cycle S1-S4.

[0031] Taking the mechanical instrument as an example, in S3: the mechanical instrument has a pointer and several green and red LED background lights set under the pointer. When it is determined that the current speed is not exceeded, the green LED background light is controlled to light up and transmit light through the pointer. The bod...

Abstract

The invention discloses an overspeed alarm method based on an automobile instrument. The method adopts a mechanical or liquid crystal instrument for alarm display, and comprises the following steps: S1, acquiring speed limit information of a current road section in real time on a CAN network of a whole automobile; S2, comparing with the current actual vehicle speed, and judging the current overspeed state; S3, carrying out corresponding alarm display by controlling the pointer color of the mechanical or liquid crystal instrument according to whether the vehicle is overspeed or not; and S4, circulating the step S1-S4. The current road speed limit information is acquired and compared with the actual vehicle speed, and the pointer is controlled to present different colors so as to realize overspeed alarm.

Description

technical field [0001] The invention belongs to vehicle speed alarm technology, in particular to an overspeed alarm method based on an automobile instrument. Background technique [0002] At present, more and more attention is paid to the safe driving of automobiles, especially speeding often brings very serious traffic accidents. At present, in the process of driving a car, there are measures such as roadside signs and speed limit signs to warn the speed of the car. However, for the vehicle's own functions, only when there is navigation, will there be voice speed limit reminders and broadcasts. The driver's vehicle is speeding. [0003] Therefore, existing vehicle speed alarm shortcoming is: [0004] 1. For vehicles without navigation: the speed limit sign needs to be observed from a different perspective, which has potential safety hazards, and there are also defects such as uncertain speed limit sign positions, a small number of speed limit signs, and the inability to w...
