Detailed Description

The embodiment of the invention provides a sound production control method and system of an active sound wave device, and solves the technical problem that passive sound production of the active sound wave device in the prior art is easy to encourage users to accelerate and increase oil consumption.

In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

As shown in fig. 1, the sound production control method of the active sound wave device of the present embodiment includes:

step S1, acquiring the actual accelerator opening and the operation parameters of the vehicle, wherein the operation parameters comprise any one or more of the engine speed, the engine torque and the gear;

step S2, determining a recommended accelerator opening of the vehicle according to the operation parameters, wherein the recommended accelerator opening is an accelerator opening which saves more fuel than the actual accelerator opening;

step S3, calculating the deviation degree of the actual accelerator opening from the recommended accelerator opening;

and step S4, changing the sound signal sent by the active sound wave device according to the deviation degree to remind the driver to adjust the actual accelerator opening to the recommended accelerator opening.

In step S1, the operation parameter represents a current operating condition of the vehicle, and the accelerator opening that is more fuel-efficient than the actual accelerator opening under the current operating condition can be determined according to the operation parameter, where the more fuel-efficient accelerator opening may be a specific value or a range, and the more fuel-efficient accelerator opening than the actual accelerator opening is preferably the most fuel-efficient accelerator opening. It is contemplated that the more comprehensive the factors considered, the more accurate the determined fuel-efficient throttle opening, and thus the operating parameters in this embodiment may include engine speed, engine torque, and gear. Of course, the operating parameters may also include further parameters in order to increase the accuracy of the determined fuel-efficient throttle opening as much as possible.

In step S2, the recommended accelerator opening is preferably the most fuel-efficient accelerator opening under certain conditions, and a conventional neural network training method may be used to obtain a more accurate recommended accelerator opening under various working conditions, and if no sample training is performed under the conditions, the host plant may also customize a set of rules for determining the recommended accelerator opening, that is, a determination function P (n, t, g, …) of the recommended accelerator opening, according to the power characteristics of the vehicle and the fuel characteristics of the engine, where P is the recommended accelerator opening, n is the engine speed, t is the engine torque, and g is the gear. The accuracy of the function is determined to only influence the oil saving effect, and the more accurate the oil saving effect, the better the oil saving effect.

In step S3, it is considered that the purpose of this embodiment is to remind the driver to adjust the accelerator opening to the recommended accelerator opening in the following driving process by the sound signal emitted by the active sound wave device to reduce the oil consumption, but the active sound wave device itself always emits sound, and cannot remind the driver to adjust the accelerator opening by controlling the active sound wave device to emit sound when the actual accelerator opening deviates from the recommended accelerator opening, and only can remind the driver by changing the sound signal, and the change of the sound signal depends on the deviation degree of the actual accelerator opening from the recommended accelerator opening. Step S3 includes: k is | P-Pt |/P, K is the degree of deviation, P is the recommended accelerator opening, and Pt is the actual accelerator opening. In step S4, the principle of changing the sound signal is that the larger the deviation degree is, the more obvious the change of the sound signal is, and the change of the sound signal can be embodied as any type of change such as loudness, timbre, tone, etc.

As can be seen from the above, in the present embodiment, the recommended accelerator opening of the vehicle is determined according to the operating parameters, the deviation degree of the actual accelerator opening from the recommended accelerator opening is calculated, the sound signal emitted by the active sound wave device is changed according to the deviation degree, the driver can be reminded to adjust the accelerator opening to a more oil-saving position by changing the sound signal emitted by the active sound wave device to reduce oil consumption, the sound signal is in an active status, and the change direction of the accelerator opening can be determined.

Theoretically, if the vehicle is not limited by external factors, the recommended accelerator opening is necessarily the most fuel-efficient accelerator opening, but when the driver is reminded to adjust the actual accelerator opening to the recommended accelerator opening by changing the sound signal emitted by the active sound wave device, the vehicle speed of the vehicle may be reduced or increased, and if there is a vehicle in front of the vehicle, it is necessary to ensure that the distance between the vehicle and the vehicle in front is within a safe range. For this reason, the step S2 in this embodiment preferably includes: acquiring the distance between the vehicle and a vehicle in front; and determining the recommended accelerator opening according to the vehicle distance between the vehicle and the vehicle in front and the running parameters. This corresponds to a factor of taking into account the vehicle distance between the host vehicle and the vehicle immediately ahead when determining the recommended accelerator opening. Specifically, determining the recommended accelerator opening according to the vehicle distance between the vehicle and the vehicle in front and the running parameters comprises the following steps:

if the distance between the vehicle and the vehicle in front is kept unchanged and is larger than the safe distance, or the distance between the vehicle and the vehicle in front is gradually reduced and has a overtaking condition, or the distance between the vehicle and the vehicle in front is gradually increased, the recommended accelerator opening determined according to the operation parameters is not limited;

and if the distance between the vehicle and the vehicle in front is kept unchanged and is smaller than the safe distance, or the distance between the vehicle and the vehicle in front is gradually reduced and the overtaking condition is not met, limiting the recommended accelerator opening determined according to the operation parameters to be smaller than the actual accelerator opening.

The present embodiment defaults to the fact that the vehicle speed of the host vehicle depends only on the actual accelerator opening degree when the vehicle distance is considered. The distance between the vehicle and the vehicle in front is kept unchanged and is larger than the safe distance, or the distance between the vehicle and the vehicle in front is gradually increased, which means that the actual accelerator opening can be randomly changed without causing the vehicle to be too close to the vehicle in front, so that potential safety hazards do not exist, and the recommended accelerator opening does not need to be limited, therefore, the determined recommended accelerator opening can be the most fuel-saving accelerator opening, and a driver can be reminded to adjust the actual accelerator opening to the most fuel-saving accelerator opening. Since the distance between the host vehicle and the vehicle directly in front is gradually reduced and the overtaking condition is met, and the lane change overtaking is possible, the step S4 includes the following steps: changing a sound signal sent by the active sound wave device according to the deviation degree so as to remind a driver to adjust the actual accelerator opening to the recommended accelerator opening and change the lane for overtaking; if the loudness of the sound signal can be changed according to the deviation degree to remind the driver to adjust the actual accelerator opening to the recommended accelerator opening, and the tone of the sound signal is changed to remind the driver to change lanes and overtake. The distance between the vehicle and the vehicle in front is kept unchanged and is smaller than the safe distance, or the distance between the vehicle and the vehicle in front is gradually reduced and has no overtaking condition, which represents that potential safety hazard exists between the vehicle and the vehicle in front, the distance needs to be increased, the vehicle speed of the vehicle needs to be reduced, namely the actual accelerator opening needs to be reduced, a driver is reminded to reduce the actual accelerator opening so as to save oil consumption, braking is not needed to reduce the vehicle speed, and the determined recommended accelerator opening needs to be limited to be smaller than the current actual accelerator opening. In this embodiment, various operation parameters are periodically detected, and if the result of the next detection determines that the potential safety hazard still exists between the vehicle and the vehicle directly in front and the actual accelerator opening needs to be reduced, the recommended accelerator opening determined next time also needs to be limited to be smaller than the actual accelerator opening in the next detection until the potential safety hazard between the vehicle and the vehicle directly in front disappears.

As mentioned above, when the sound signal generated by the active sound wave device is changed to remind the driver to adjust the actual accelerator opening to the recommended accelerator opening, the vehicle speed of the vehicle may be reduced or increased, and if the road is limited or safety considerations are taken into consideration, the vehicle speed is limited to be not greater than the highest speed limit. For this reason, step S2 of the present embodiment includes: acquiring the speed of the vehicle; and determining the recommended accelerator opening according to the vehicle speed and the operation parameters. Thus, the vehicle speed is taken into consideration in determining the recommended accelerator opening. Specifically, determining the recommended accelerator opening according to the vehicle speed and the operation parameters comprises the following steps:

if the vehicle speed is not greater than the highest speed limit, the recommended accelerator opening determined according to the operation parameters is not limited;

and if the vehicle speed is greater than the highest speed limit, limiting the recommended accelerator opening determined according to the operation parameters to be smaller than the actual accelerator opening.

The present embodiment defaults to the fact that the vehicle speed of the host vehicle in consideration of the vehicle speed depends only on the actual accelerator opening. The vehicle speed is not more than the highest speed limit, the actual accelerator opening can be changed at will without overspeed driving, and the recommended accelerator opening is not required to be limited, so that the determined recommended accelerator opening can be the most fuel-efficient accelerator opening, and a driver can be reminded to adjust the actual accelerator opening to the most fuel-efficient accelerator opening. The vehicle speed is greater than the highest speed limit, which means that the actual accelerator opening should be reduced, i.e. the driver needs to be reminded to reduce the actual accelerator opening to save oil consumption, and the vehicle speed does not need to be reduced by braking, so that the determined recommended accelerator opening is limited to be smaller than the current actual accelerator opening, if the vehicle speed is still greater than the highest speed limit in the next detection, the next determined recommended accelerator opening is limited to be smaller than the actual accelerator opening in the next detection until the vehicle speed is smaller than the highest speed limit.

The sound signal emitting mode of the active sound wave device has various modes, the default sound signal of the embodiment is superposition of a plurality of sine waves, and the expression of a single sine wave ist is time, A is amplitude, w is frequency,is the phase. There are various sound signal changing methods for realizing the function of prompting the driver to adjust the actual accelerator opening degree, and step S5 of the present embodiment includes:

associating any characteristic parameter of the sound signal with a degree of deviation;

the greater the degree of deviation, the more pronounced the variation of the control characteristic.

The characteristic parameters of the sound signal include, but are not limited to, any one of amplitude, frequency, number of utterances and volume ratios in different directions. Taking amplitude as an example, associating A with K, the larger K is, the more obvious the change of the control A is, the larger the deviation degree is, the stronger the sound signal is, and the stronger the reminding effect is. Or may be a change of a certain number of specific frequency components, i.e. associating K with a of a certain frequency component. The change of the rhythm of the sound can also be similar to the change of the prompt degree of the reversing radar in different distances, and the K is associated with the sounding times. The active sound wave device comprises a plurality of loudspeakers arranged at different positions of front, back, left and right, and can relate the K with the volume ratios of the loudspeakers in different directions.

The present embodiment further provides a sound production control system of an active sound wave device, as shown in fig. 2, including:

the driving parameter acquisition module is used for acquiring the actual accelerator opening and the operation parameters of the vehicle, wherein the operation parameters comprise any one or more of the engine rotating speed, the engine torque and the gear;

the accelerator opening recommending module is used for determining the recommended accelerator opening of the vehicle according to the operation parameters, and the recommended accelerator opening is an accelerator opening which saves more oil than the actual accelerator opening;

and the sound signal control module is used for controlling a sound signal emitted by the active sound wave device according to the deviation degree so as to remind a driver to adjust the actual accelerator opening to the recommended accelerator opening.

According to the method and the device, the recommended accelerator opening of the vehicle is determined according to the operation parameters, the deviation degree of the actual accelerator opening from the recommended accelerator opening is calculated, the sound signal sent by the active sound wave device is changed according to the deviation degree, the driver is reminded to adjust the accelerator opening to a more oil-saving position through changing the sound signal sent by the active sound wave device so as to reduce oil consumption, the sound signal is in an active position, and the change direction of the accelerator opening can be determined.
