Technical Field

The invention belongs to the technical field of self-starting of automobile emergency lamps, and particularly relates to a self-starting control method of an automobile emergency lamp.

Background

With the increase of the automobile holding capacity, the number of automobile collision accidents is increased. Under the condition of a road condition with a fast traffic flow, if collision occurs, a link accident is easily caused; in the process of fast driving, when meeting an unexpected barrier, the front vehicle directly faces, certain reaction time is easy to avoid, and the rear vehicle is difficult to obtain information in time, so that accidents are easy to happen. Therefore, it is urgently needed to develop a method for controlling the self-starting of the automobile emergency lamp.

Disclosure of Invention

The invention aims to provide a self-starting control method for an automobile emergency lamp, which aims to solve the problem of automatic starting under the condition that a driver has no time to start the emergency lamp and avoid secondary damage caused by rear-end collision due to delayed reaction of a vehicle behind.

The purpose of the invention is realized by the following technical scheme:

a self-starting control method for an automobile emergency lamp comprises the following steps:

A. when the detection result of the ABS sensor meets the ABS starting condition, the detection value of the safety air bag sensor reaches or exceeds half of the air bag starting value, or the detection result of the EPS sensor meets the ESP starting condition, the emergency condition is judged;

B. the ECU sends an emergency lamp starting instruction to an emergency lamp;

C. the emergency lamp receives the opening instruction and is automatically opened, if the emergency lamp is started due to the fact that the ABS starting condition or the ESP starting condition is met, if normal driving can be quickly recovered within the set time, the emergency lamp is automatically closed, and if the automobile is decelerated to stop, the emergency lamp is always in an open state until the emergency lamp is manually closed.

Further, in step a, the ABS starting conditions are: when the speed of the automobile exceeds 60Km/h, if the deceleration occurs and reaches the deceleration value set by the ABS system, the ECU starts the ABS system.

Further, in step a, the ESP start conditions are: when the speed of the automobile exceeds 80Km/h, if the steering is performed to achieve the slippage of the driving wheels arranged by the ESP system or the sidesway of the automobile body with a certain amplitude occurs, the ECU starts the ESP system.

Further, in step C, the set time is 5 s.

Compared with the prior art, the invention has the beneficial effects that:

the invention provides a self-starting control strategy for an automobile emergency lamp, which is characterized in that in the process of high-speed running of an automobile, under the emergency conditions of strong collision, emergency braking, emergency avoidance or dangerous road conditions and the like, the emergency lamp is automatically started according to the condition that the detection value of a sensor exceeds a limit value, so as to remind that the front of the automobile is abnormal later, an avoidance measure is taken in advance, and unnecessary loss is reduced; the method effectively reminds the rear vehicle to avoid ahead without additionally increasing automobile parts, reduces the probability of causing the vehicle accident, improves the road circulation speed and avoids the collision vehicle from being damaged by rear-end collision of the rear vehicle.

the present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

As shown in fig. 1-3, the method for controlling the self-starting of the emergency lamp of the automobile comprises the following steps:

A. when the detection result of the ABS sensor meets the ABS starting condition, the detection value of the safety air bag sensor reaches or exceeds half of the air bag starting value, or the detection result of the EPS sensor meets the ESP starting condition, the emergency condition is judged;

B. the ECU sends an emergency lamp starting instruction to an emergency lamp;

C. if the emergency lamp is started due to the fact that the ABS starting condition or the ESP starting condition is met, if normal driving can be quickly recovered within the set time (for example, 5s, the normal driving can be set in an ECU program), the emergency lamp is automatically turned off, and if the automobile is decelerated to stop, the emergency lamp is always in an on state until the emergency lamp is manually turned off.

Step A, the ABS starting conditions are as follows: when the speed of the automobile exceeds 60Km/h, if the deceleration occurs and reaches the deceleration value set by the ABS system, the ECU starts the ABS system. In the development of ABS systems, a deceleration value is set (the specific deceleration value is set according to the positioning of the vehicle and the requirements of each manufacturer in actual use), and when the deceleration reaches this value, the ABS is activated.

Step A, the ESP starting conditions are as follows: when the speed of the automobile exceeds 80Km/h, if the steering is performed to achieve the slipping of a driving wheel set by the ESP system or the vehicle body generates a certain amplitude of side sway (the specific side sway angle is set according to the positioning of the vehicle and the requirement of each manufacturer in actual application), the ECU starts the ESP system. When the ESP system is developed, the ECU starts the ESP system when the driving wheels slip or the vehicle body generates a certain amplitude of side sway.

Examples

1. When the speed of the automobile is over 60Km/h, if the ABS system is started due to deceleration, the emergency lamp is judged to be in an emergency state, if normal driving is recovered quickly, the emergency lamp is automatically turned off, and if the automobile is decelerated to stop, the emergency lamp is always in an on state until the emergency lamp is manually turned off;

2. when the automobile collides, if the detection value of the safety air bag sensor reaches half of the starting value of the air bag, the automobile is judged to be in an emergency, and the emergency lamp is automatically started until the emergency lamp is manually turned off;

3. when the speed of the automobile is over 80Km/h, if steering causes the starting of an ESP (or VDC/VSC/VSA/DSC) system, the emergency condition is judged, the emergency lamp is automatically started, if normal driving is recovered quickly, the emergency lamp is automatically turned off, and if the automobile is decelerated to stop, the emergency lamp is always in an on state until the emergency lamp is manually turned off.

The method effectively reminds the rear vehicle to avoid ahead without additionally increasing automobile parts, reduces the probability of causing the vehicle accident, improves the road circulation speed and avoids the collision vehicle from being damaged by rear-end collision of the rear vehicle.
