DRIVING SAFETY WARNING METHOD AND DEVICE THEREFOR
First Claim
1. A driving safety warning method, comprising the following steps:
- switching on a driving safety warning device installed in a car to enable a driving safety warning program for the device;
the driving safety warning device determining whether a driving speed value of the car exceeds a preset value;
if yes, a driving safety warning function of the device being actuated;
the driving safety warning device determining whether a deviation angular speed value of the car exceeds a preset maximum safety deviation angular speed value;
if yes, a warning sound being emitted;
the driving safety warning device determining whether a deviation angular speed value of the car exceeds a preset safety deviation angular speed value for wandering car;
if yes, further determining whether a timer of the device is enabled and a reverse sway occurs while the timer is counting; and
if yes, a warning sound being emitted.

Abstract
A driving safety warning device includes a central processing unit (CPU); an acceleration sensor for sensing an acceleration value of a car having the driving safety warning device installed therein, and sending the sensed acceleration value to the CPU for calculating, so as to obtain a driving speed value; and a gyro sensor for sensing a deviation angular speed value of the car in moving, and sending the sensed deviation angular speed value to the CPU for calculating. When the obtained driving speed value exceeds a preset value, a driving safety warning function is actuated; and when the obtained deviation angular speed value exceeds a preset maximum safety deviation angular speed value or exceeds a preset safety deviation angular speed value for wandering car while a timer is enabled and a reverse sway occurs when the timer is counting, a warning sound is emitted to remind the driver.
