Example two

FIG. 2 is a flow chart illustrating a method of active hood control for use in a terminal according to an exemplary embodiment, the method comprising the steps of:

step 201, when the sensing unit receives a data obtaining request, vehicle data and external data are obtained respectively and sent to the decision unit.

Wherein the vehicle data includes: vehicle speed data and front bumper acceleration data, the ambient data comprising: atmospheric pressure data, obstacle data, and pressure within the pressure tube data.

Step 202, comparing the vehicle speed data with a speed threshold range, identifying and executing a corresponding instruction, and specifically comprising the following steps:

judging whether a speed threshold range is met or not according to the vehicle speed data, wherein the speed threshold range is 25 & ltu & lt 55, u is the vehicle speed data, and the speed threshold range is obtained through simulation or test:

if the speed threshold range is met, comparing and identifying the pressure data and the atmospheric pressure data in the pressure pipe with a first preset condition;

and if the speed threshold range is not met, repeatedly acquiring the vehicle data and the external data.

Step 203, comparing the pressure data in the pressure pipe and the atmospheric pressure data with a first preset condition, identifying and executing a corresponding control command, wherein the specific steps comprise:

obtaining a pressure change rate through pressure data in the pressure pipe and atmospheric pressure data;

judging whether a first preset condition is met or not according to the pressure change rate, wherein the first preset condition is that psi is larger than or equal to T0, psi is the pressure change rate, and T0 is a pressure change rate threshold;

if the first preset condition is met, the decision result of the decision unit is that the area right in front of the vehicle collides with the pedestrian, and a control instruction is transmitted to the execution unit;

and if the first preset condition is not met, comparing and identifying the obstacle data with a second preset condition.

The pressure change rate threshold value is dynamically changed along with the vehicle speed, a u-T0 curve is obtained through simulation or experiments, and T0 under the corresponding vehicle speed is obtained on the curve according to the vehicle speed during collision.

Since children under 6 years old or 5% of women have small height and weight and cannot collide with the engine hood after the vehicle collides with the children under 6 years old or 5% of women, the active engine hood implementation method only protects the heads of the children over 6 years old and the women over 5% of the children under 6 years old or 5% of women in principle. The PDI2 module (pedistrian Detection impact-2) is generally considered to be the most difficult Pedestrian dummy to assess in the evaluation of active hood systems, and therefore the PDI2 module is used in the present invention to perform acceleration and pressure tests or simulations.

The PDI2 module impacts the area right in front of the vehicle at the speed of 25km/h, 35km/h, 45km/h and 55km/h respectively, the pressure change process in the pressure pipe is collected and recorded to obtain 4 pressure change curves, 80% of the peak value of the 4 pressure curves is taken as T0 under the corresponding vehicle speed, and a u-T0 curve is obtained, as shown in FIG. 4.

Step 204, comparing the obstacle data with a second preset condition, identifying and executing a corresponding instruction, and specifically comprising the following steps:

judging whether a second preset condition is met or not through the obstacle data, wherein the second preset condition is that d is 1, and d is a parking radar signal:

if the second preset condition is met, comparing and identifying the acceleration data of the front bumper with a third preset condition,

and if the second preset condition is not met, repeatedly acquiring the vehicle data and the external data.

Step 205, comparing the acceleration data of the front bumper with a third preset condition, identifying and executing a corresponding instruction, wherein the specific steps comprise:

obtaining an acceleration change value from the front bumper acceleration data and the historical front bumper acceleration data,

judging whether a third preset condition is met or not according to the acceleration change value, wherein the third preset condition is that delta a is greater than a1, delta a is an acceleration change value, and a1 is an acceleration change value threshold:

if the third preset condition is met, the decision result of the decision unit is that the front corner area of the vehicle collides with the pedestrian, and a control instruction is transmitted to the execution unit;

and if the third preset condition is not met, repeatedly acquiring the vehicle data and the external data.

The acceleration change value threshold is dynamically changed along with the vehicle speed as same as T0, a u-a1 curve is obtained through simulation or experiment, and the acceleration change value threshold under the corresponding vehicle speed is obtained on the curve according to the vehicle speed when collision occurs.

Similarly, since children under 6 years old or 5% of women have small height and weight and the vehicle will not collide with the hood after collision, the active hood implementation method in the invention is limited to children under 6 years old or 5% of women, and basically protects only the heads of children over 6 years old and 5% of women. The PDI2 module (pedistrian Detection impact-2) is generally considered to be the most difficult Pedestrian dummy to assess in the evaluation of active hood systems, and therefore the PDI2 module is used in the present invention to perform acceleration and pressure tests or simulations.

The PDI2 module impacts front corner areas of the vehicle at speeds of 25km/h, 35km/h, 45km/h and 55km/h respectively, the acceleration change process is collected and recorded, 4 acceleration change curves are obtained, 80% of the peak values of the 4 acceleration change curves are taken as a1 under the corresponding vehicle speed, and a u-a1 curve is obtained, and is shown in FIG. 3.

And step 206, the execution unit controls the active hood to automatically bounce according to the control command.

After the execution unit receives the control instruction sent by the decision unit, the execution unit controls the action of the execution mechanism, so that the rear end of the engine hood is quickly bounced, and the vertical distance between the engine hood and a hard point in the engine room is increased.

The engine hood bounce decision-making method based on the multi-parameter is used for making the engine hood bounce decision, the parameters are insensitive to environmental information such as external illumination and the like, the reliability is higher, and false triggering and missed triggering can be avoided under the condition that no pedestrian collides. The front of the vehicle is divided into two areas, and different decision algorithms are adopted by the decision unit aiming at the two areas. For the area right in front of the vehicle, the prior art uses the pressure change delta p in the pressure pipe to make the decision of hood bounce, but the delta p is greatly influenced by the ambient temperature. The engine hood bounce decision is mainly made based on the pressure change rate psi in the pressure pipe, and the pressure change rate psi can eliminate the influence of the ambient temperature.
