In view of the foregoing problems, embodiments of the present application provide a driving assistance method and apparatus for a vehicle, an electronic device, and a storage medium, which are described below by way of embodiments.
For the convenience of understanding of the present application, the technical solutions provided in the present application will be described in detail with reference to specific embodiments.
Referring to fig. 1, a method for assisting driving of a vehicle provided in an embodiment of the present application is executed by a vehicle microcontroller, and the method includes:
and S101, responding to a control command to start an anti-light-reflecting mode.
Specifically, the daytime, the night or the external environment can be judged through a headlight dimming module (ADIM) of the vehicle body and the duty ratio of pwm (pulse width modulation) output by the ADIM, and if an Electronic Control Unit (ECU) of the vehicle body judges that the headlight turning-on condition is met, an instruction command for turning on the anti-glare mode is synchronously sent with a can message of the ECU turning-on the headlight. The light sensor and the single ECU can be used for integrating the ECU into a vehicle body can network, the illumination information of the external environment is sent to an MCU (Micro control unit) or an SOC (System on Chip) through the can network for judging the lighting condition of the external environment, and if the condition of starting the anti-light reflection mode is met, a control instruction is generated.
S102, a first light intensity value detected by a first illuminance sensor installed at a first target installation position of a target exterior mirror of the vehicle is obtained, and the first light intensity value is an intensity value of external light irradiated on the target exterior mirror by an external light source.
As shown in fig. 6, the first illuminance sensor 610 is here mounted at a first target mounting position of the target exterior mirror 600 of the vehicle. The target exterior mirror 600 is either a left mirror or a right mirror on the outside of the vehicle. The first target mounting position may be in a plane of a mirror side of the exterior mirror. The first light intensity value obtained by the first illuminance sensor 610 is an intensity value of external light from the external light source to the target exterior mirror 600, that is, an intensity value of strong light from the rear headlights.
S103, adjusting the target exterior mirror to a target adjusting position according to the comparison result of the first light intensity value and the first light intensity threshold value so as to change the reflection angle of the target exterior mirror to the external light.
The first light intensity threshold is a preset light intensity threshold, and is a fixed value calibrated by research personnel through multiple experiments, and when the first light intensity value is greater than the first light intensity threshold, it is considered that the current target rearview mirror is irradiated by strong light and reflected into the cab, and at this time, the position of the target rearview mirror 600 needs to be adjusted. The target adjustment position is a preset outside mirror position, and when the outside mirror is adjusted to the target outside mirror 600, the reflection angle of the outside mirror to the external light is changed, and the light reflected by the outside mirror is not emitted into the cab.
And S104, controlling the rear camera of the vehicle to be started so as to acquire video data behind the vehicle and sending the video data to the vehicle-mounted display of the vehicle for displaying.
The rear camera here can be mounted on the rear of the vehicle, such as on the rear bumper, for obtaining the situation behind the vehicle. After the anti-reflection mode is determined to be started, the target exterior mirror 600 is controlled to be adjusted to the target position, meanwhile, the rear camera is also started, video data of the rear driving part of the vehicle is played through the vehicle-mounted display, and therefore a driver can know the road condition after the vehicle is turned on in real time under the condition that the exterior mirror is adjusted.
And S105, obtaining a second light intensity value detected by a second illumination sensor installed at a second target installation position of the target exterior mirror, wherein the second light intensity value is an intensity value of external light which is acquired by the second illumination sensor and irradiates the target exterior mirror when the target exterior mirror is at the target adjustment position.
As shown in fig. 7, the second target installation position here is on the surface of the opposite side of the target exterior mirror 600 from the vehicle. When the target rearview mirror is adjusted to the target adjustment position, the intensity value of the external light irradiated from the external light source onto the target rearview mirror 600 may be detected by the second light illuminance sensor 620. The purpose of obtaining the second light intensity value detected by the second illuminance sensor 620 is to determine whether the intensity of the current external light is decreased, that is, whether the headlight of the rear vehicle is turned off.
And S106, determining whether to exit the anti-reflection mode according to the second light intensity value.
Specifically, whether the second light intensity value is smaller than a second light intensity threshold value or not is determined, and if the second light intensity value is smaller than the second light intensity threshold value and lasts for a preset time, the anti-reflection mode is determined to exit. The second light intensity threshold value is smaller than the first light intensity threshold value, the second light intensity threshold value is a preset light intensity threshold value, when the second light intensity threshold value is smaller than the second light intensity threshold value, the far-reaching headlamp of the rear vehicle can be considered to be closed at the moment, no strong light can be reflected into the cab, and the anti-reflection mode is exited.
The auxiliary driving method of the vehicle obtains a first light intensity value detected by a first light intensity sensor 610 installed at a first target installation position of a target exterior mirror 600 of the vehicle by starting an anti-reflection mode, adjusts the target exterior mirror 600 to a target adjustment position according to a comparison result of the first light intensity value and a first light intensity threshold value, and simultaneously displays a situation video of the rear of the vehicle through a vehicle-mounted display, so that a driver can observe the situation of the rear of the vehicle while preventing the left and right exterior mirrors from reflecting strong light to a cab.
Referring to fig. 2, a method for adjusting a target exterior mirror according to an embodiment of the present application includes:
s201, determining whether the first light intensity value is greater than a first light intensity threshold value;
s202, if the first light intensity value is larger than the first light intensity threshold value, the target exterior mirror is controlled to rotate a first preset angle value towards a first preset direction, and the target exterior mirror is controlled to rotate a second preset angle value towards a second preset direction, so that the target exterior mirror is adjusted to a target adjusting position.
The first preset direction may be one of a clockwise direction or a counterclockwise direction about the first mounting axis of the target exterior mirror, and the second preset direction may be one of a clockwise direction or a counterclockwise direction about the second mounting axis of the target exterior mirror, wherein the first mounting axis is perpendicular to the second mounting axis, i.e., one is to turn the target exterior mirror 600 upside down and one is to rotate the target exterior mirror 600 left and right. The first preset angle value and the second preset angle value are preset angle values and are fixed angle values calibrated by research personnel through multiple experiments. Illustratively, the target exterior mirror 600 may be turned downward by 30 ° while being rotated by 45 ° to a side away from the vehicle to reach the target adjustment position. When the target exterior mirror 600 is adjusted to the target adjustment position, the strong light originally reflected into the cab direction can be reflected to other directions, so that the driver in the cab is prevented from being influenced by the strong light, and the driving of the vehicle is further influenced.
Referring to fig. 3, another method for adjusting a target exterior mirror according to an embodiment of the present application includes:
s301, determining whether the currently detected first light intensity value is greater than a first light intensity threshold value;
s302, if the currently detected first light intensity value is larger than the first light intensity threshold value, controlling the target exterior mirror to rotate to a third preset angle value in the first preset direction, and/or controlling the target exterior mirror to rotate to a fourth preset angle value in the second preset direction.
The third preset angle value and the fourth preset angle value are preset fixed angle values, the first preset angle value is larger than the third preset angle value, the second preset angle value is larger than the fourth preset angle value, and the third preset angle value and the fourth preset angle value are preset angle values and are fixed angle values calibrated by research personnel through multiple experiments. For example, when the detected first light intensity value is greater than the first light intensity threshold value, the target exterior mirror 600 may be controlled to be turned down by 10 ° or rotated by 10 ° to the side away from the vehicle, and may be further turned down by 10 ° while being rotated by 10 ° to the side away from the vehicle.
S303, determining whether the position of the rotated target exterior mirror is adjusted to a target adjusting position;
and S304, if the position of the rotated target exterior mirror is not adjusted to the target adjusting position, returning to the step S301.
Specifically, if the position of the target exterior mirror 600 adjusted in step S302 is the same as the position in one of the first preset direction or the second preset direction of the target adjustment position, or both the first preset direction and the second preset direction, it is determined that the position of the rotated target exterior mirror 600 has been adjusted to the target adjustment position. If it is determined that the position of the rotated target exterior mirror 600 is not adjusted to the target adjustment position, the target exterior mirror 600 is continuously controlled to be turned down by 10 ° or rotated by 10 ° to the side far from the vehicle, and may be further turned down by 10 ° while being rotated by 10 ° to the side far from the vehicle, but the manner of each adjustment is the same. Until it is determined that the position of the rotated target exterior mirror 600 is adjusted to the target adjustment position, the target exterior mirror 600 is not adjusted.
Further, the control instruction is obtained by the following method:
in the first situation, a third light intensity value detected by a third illumination sensor of the vehicle is obtained, the third light intensity value represents an intensity value of ambient light of a running environment where the vehicle is located, and when the third light intensity value is smaller than a preset ambient light intensity value, a control instruction is generated and used for controlling the vehicle to start a headlamp and start an anti-reflection mode.
In this case, the third illumination sensor may be an environment sensor of the vehicle itself, which is used for detecting the intensity value of the ambient light of the running environment in which the vehicle is located, and may be generally disposed on the endoscope of the vehicle. When the third light intensity value is smaller than the preset environment pipeline intensity value, it can be determined that the driving environment where the vehicle is located may be at night or in a tunnel in a dark environment or even in an environment without illumination, and the driving vehicle can usually turn on the high beam illumination temporarily at this moment, so that a control instruction is generated to control to turn on the high beam in the headlamp of the vehicle, and the anti-reflection mode is turned on at the same time to prevent the light of the high beam of the rear vehicle from being reflected to the cab of the front vehicle.
And in the second situation, a control instruction is generated in response to the starting operation issued by the user and used for starting the anti-reflection mode, and the control instruction is used for controlling the vehicle to start the anti-reflection mode.
In this case, the driver can manually turn on the anti-reflection mode, and the turning-on operation of the anti-reflection mode can be issued in the form of an in-vehicle display or a key, etc., to generate a control instruction to turn on the anti-reflection mode. The driver can manually start the anti-reflection mode according to actual needs or own driving habits, and the driving safety of the driver is ensured.
Referring to fig. 4, a method for restoring a target exterior mirror according to an embodiment of the present application includes:
and S401, recording the current position information of the target exterior mirror at the moment when the anti-reflection mode is started.
S402, determining whether the current position information of the target exterior mirror is consistent with the stored historical position information;
s403, if the current position information of the target exterior mirror is inconsistent with the historical position information of the target exterior mirror, replacing the historical position information with the current position information of the target exterior mirror, and storing the historical position information;
and S404, when the anti-reflection mode is determined to exit, restoring the position of the target exterior mirror according to the stored historical position information.
Specifically, while the anti-reflection mode is determined to be turned on, the current position information of the target exterior mirror 600 is recorded, whether the current position information of the target exterior mirror 600 is the same as the stored historical position information is determined, and if not, the current position information of the target exterior mirror needs to be replaced by the historical position information. When the anti-reflection mode is exited, the historical position information of the target exterior mirror 600 stored in the memory is acquired, and the position of the target exterior mirror 600 is restored to the position where the historical position information is consistent.
According to the method and the device, the historical position of the target exterior mirror is stored, when the target exterior mirror is withdrawn from the anti-reflection mode, the target exterior mirror is restored to the position before the anti-reflection mode is started, the position change of the exterior mirror caused by adjusting the target exterior mirror is avoided, the use of the target exterior mirror is influenced, and the safety of a driver driving a vehicle is ensured.
Furthermore, after the target exterior mirror is adjusted to the target adjusting position, if the first light intensity value is greater than the first light intensity threshold value, the target exterior mirror is adjusted to the safe position.
The safety position here can be an adjustable limit position in a first preset direction and/or a second preset direction of the adjustment of the exterior mirror. Because the environment in which the vehicle runs changes rapidly and the situation is complex, after the target exterior mirror 600 is adjusted to the target adjustment position, if the first light intensity value is still greater than the first light intensity threshold value, that is, strong light still reflects into the cab at the moment, the target exterior mirror 600 is directly adjusted to the safe position, so that the situation that no strong light reflects into the cab is ensured, and the reliability of the method is further improved.
The specific embodiment is as follows:
the application provides a method for self-adaptive adjustment of an exterior mirror of a vehicle, which specifically comprises the following steps:
(1) Whether the current environment outside the automobile is at night is detected through the illuminance, and whether the driver starts the anti-reflection mode is determined.
(2) Before the anti-reflection mode is started, the angle of the target exterior mirror 600 currently set by the driver is maintained and stored, so that the vehicle can automatically return to the original angle of the target exterior mirror 600 after exiting the anti-reflection mode.
(3) The rear vehicle starts a high beam, strong light irradiates the target exterior mirror 600, and the anti-reflection mode is triggered to adjust the target exterior mirror 600 to a target adjusting position. Meanwhile, the central control display screen and the rear reversing camera are in linkage fit, the reversing camera or a special camera with a backlight shooting function is opened, and the condition behind the vehicle is projected onto the central control display screen through the camera.
(4) When the strong light on the rearview mirror disappears, the anti-reflection mode is exited, and the target exterior mirror 600 is reset.
By the method, the problem of vehicle light interference can be avoided, a driver can observe the conditions behind the vehicle through the rearview mirror in scenes such as night, driving safety is guaranteed, and traffic accidents are avoided.
Based on the same inventive concept, the embodiment of the present application further provides a driving assistance device of a vehicle corresponding to the driving assistance method of the vehicle, and since the principle of the driving assistance device of the vehicle in the embodiment of the present application for solving the problem is similar to the driving assistance method of the vehicle in the embodiment of the present application, the implementation of the driving assistance device of the vehicle may refer to the implementation of the method, and repeated details are omitted.
