in the step S3: the EMS system is used for acquiring the rotating speed information of the vehicle in real time, and when the rotating speed is up to more than 3000rpm within 500ms, judging that the driver has a third index of road rage driving behavior;
in the step S4: the weight acceleration sensor is used for acquiring the acceleration information of the vehicle in real time, acquiring the sudden deceleration and the sudden acceleration which alternately appear in the vehicle in unit time, and judging the fourth index of the road rage driving behavior of the driver;
in the step S5: and the central processing unit receives the first index, the second index, the third index and the fourth index in real time, and judges the behavior of the driver in the intentional road rage according to the simultaneous existence of the first index, the second index, the third index and the fourth index.
9. The driver' S driving behavior reminding method as claimed in claim 8, wherein in the step S5: the central processor judges whether the driver has road rage driving behavior according to one or more of the facial recognition information, the lane departure information, the rotating speed information and the acceleration information; and/or the presence of a gas in the gas,
in the step S5: the central processing unit judges once every five seconds according to the first index, the second index, the third index and the fourth index; and/or the presence of a gas in the gas,
in the step S5: when the central processing unit continuously judges the intentional road rage driving behavior for three times, the central processing unit forcibly controls the vehicle to reduce the speed through the TCU module; and/or the presence of a gas in the gas,
in the step S6: when the central processing unit judges that the driver has road rage driving behavior, the central processing unit forcibly controls the vehicle to reduce the speed through the TCU module; and/or the presence of a gas in the gas,
in the step S6: if the central processing unit continuously sends out alarm reminding, when any one of the first index, the second index, the third index and the fourth index is not satisfied, the road rage driving behavior is judged to be stopped, the central processing unit sends a dangerous driving relieving reminding signal to the associated controller, and the alarm device stops giving an alarm.
10. An automobile, characterized by comprising the driver driving behavior reminding system of any one of the preceding claims 1 to 5; and/or, a driver driving behavior reminding method comprising any one of the above claims 6 to 9.
