Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an ejection acceleration safety control method for an electric vehicle according to an embodiment of the present invention.
In a specific implementation manner of the present invention, an embodiment of the present invention provides a method for controlling ejection acceleration safety of an electric vehicle, for controlling ejection acceleration of the electric vehicle, including:
step S11: acquiring current driver safety condition information, current vehicle condition information and current road surface condition information of the electric automobile;
step S12: judging whether the current driver safety condition information, the current vehicle condition information and the current road surface condition information meet preset safety conditions or not;
step S13: if yes, starting an automobile ejection acceleration preparation action; if not, the locking automobile ejection accelerating function is in a forbidden state.
In the embodiment of the invention, firstly, the electric automobile can continuously acquire the current safety condition information of the driver, the current vehicle condition information and the current road surface condition information when being started. Only when the conditions simultaneously meet the preset safety conditions, the subsequent operation can be continued.
Specifically, in order to obtain the current safety condition information of the driver, a gravity sensor can be used for detecting whether a person is on a driver seat, and a tension sensor is used for detecting whether an ejection safety belt is fastened; whether the ejection vehicle door is closed or not, whether front and rear hatches of the vehicle are closed or not and the like can be determined, and of course, the health condition of the driver can be basically detected, for example, whether the body temperature of the current driver is normal or not and whether the heart rate is normal or not are detected by using an infrared thermometer.
In order to acquire the current vehicle condition information, it may be detected whether ((BMS 30s maximum allowable discharge power)/motor 30s peak power) is greater than 1.2 times; whether each system of the automobile has a fault or not and whether the tire pressure of the automobile is normal or not can also include other indexes, and if one index does not meet the preset condition, the next step cannot be carried out for a long time; in order to obtain the current road condition information, a GPS navigator can be adopted, and the road condition information in navigation, for example, navigation displays that no congestion exists in the road within 1km/h, of course, a sensor can be arranged right in front of the vehicle head to detect whether an object in front obstructs the ejection for acceleration, or more other current road condition information, for example, whether rain, snow, fog and the like exist, is not beneficial to the ejection acceleration of the vehicle.
That is, the driver safety conditions are: the driver is inside the vehicle and fastens the seat belts and closes all the doors and the front and rear hatch covers are closed; the vehicle safety conditions are: BMS 30s discharge power/motor 30s peak power >1.2& & vehicle no fault & tire pressure normal; the road condition safety conditions are as follows: navigation shows that the road in the vicinity of 1km/h is not congested. Wherein, the 30s discharge power is the peak power that the battery can reach for 30 seconds; the peak power of the motor 30s is the peak power that the motor can reach for 30 seconds.
Further, under the condition that current driver safety condition information, current vehicle condition information, current road surface condition information accord with preset safety condition, in order to further guarantee the smooth going on of the ejection acceleration of car, can also further, can also detect the fender position of car, whether brake light braking state can carry out ejection acceleration smoothly and judge, specifically: whether the electric automobile meets any one of a first condition, a second condition and a third condition can be judged; if yes, starting an automobile ejection acceleration preparation action; wherein the first condition is: the current vehicle speed is zero and the gear is N gear, and the vehicle is in a braking state; the second condition is that the current vehicle speed is zero, the gear is N gear and the EPB is started; and the third condition is that the current vehicle speed is zero and the gear is P gear.
At this time, the vehicle catapulting acceleration action can be started after the catapulting acceleration enabling instruction is received, and only after the catapulting acceleration enabling instruction is received, the subsequent action can be carried out, that is, the subsequent program can be operated, for example, the driver can be allowed to step on the accelerator and brake simultaneously, and the battery and the motor are controlled to work according to a short time (for example, 10 peak power). In practice, the driver may receive the launch acceleration enabling instruction by using a mechanical key or a touch screen, or may receive the launch acceleration enabling instruction on an existing electronic control entertainment touch display screen.
Certainly, after the enabling preparation condition is completed, the safety problem cannot be relaxed, so that the current safety condition information of the driver, the current vehicle condition information and the current road surface condition information need to be acquired in real time, and after the enabling preparation condition is completed, whether the current safety condition information of the driver, the current vehicle condition information and the current road surface condition information meet the preset safety condition is continuously judged; if not, the ejection acceleration process is exited. Thereby, further guarantee driving safety. That is, steps S11, S12, S13 are always running during the start of the ejection safety control, and if a safety problem occurs, the ejection acceleration process is immediately exited.
It should be noted that, in order to prevent the driver from forgetting that the vehicle is currently in the ejection acceleration process due to the carelessness of the driver after starting the vehicle ejection acceleration action, for example, the driver may forget that the vehicle is currently in the ejection acceleration state after starting the vehicle ejection acceleration function, and the driver may be dangerous if continuing the action, the driver may further perform the following actions after starting the vehicle ejection acceleration action: after finishing the preparation action of ejection acceleration, judging whether the current vehicle speed is zero and continuously exceeds a preset time length; if so, exiting the ejection acceleration process. That is, after the vehicle is Ready for catapult acceleration (at this time, the vehicle is in a one-touch state, and "catapult acceleration activation" may be displayed by the meter orange text), if the driver does not further operate to start the vehicle, after a preset time period (for example, 1 minute or 2 minutes may be set, and other time periods may be used as well), the vehicle automatically exits the catapult acceleration process to protect the driver from exceeding the catapult acceleration predicted by the driver, at this time, the meter may display "catapult acceleration waiting" in green text for the next operation of the driver, and when the meter displays "catapult acceleration Ready" again, the catapult acceleration activation switch may be pressed again.
When the automobile breaks down, the vehicle condition information can be considered to be not in accordance with the preset condition, for example, a communication fault between a VCU (electric automobile whole controller) and an EHU (electric control entertainment unit) occurs; the electronic control system can quit ejection acceleration, simultaneously displays 'ejection acceleration quit' by a green table, and can automatically start TCS and VDC functions of an ESP system, remove a forced instruction at the lowest position and remove a forced instruction of full-time four-wheel drive for some electric vehicles.
The invention provides a safety control method for ejection acceleration of an electric automobile, which utilizes the acquired condition information of people, vehicles and environments to carry out safety judgment, allows the next step of automobile ejection acceleration to be carried out to enable the action under the condition that the people, the vehicles and the environments are beneficial to the ejection acceleration of the electric automobile, and forbids the ejection acceleration function of the automobile, thereby improving the driving pleasure of a driver and the movement performance of the automobile and ensuring the driving safety of the electric automobile.
