Technical Field

The invention relates to the technical field of vehicles, in particular to a reversing radar system and a motor vehicle.

Background

The radar for backing car is one of the important auxiliary devices of modern car, and its main principle is that the ultrasonic wave emitted by radar probe can be used for measuring and calculating the distance of obstacle, and according to the distance the alarm with different frequencies can be given out so as to assist driver and passenger to implement the operations of car parking or backing car, etc.

Although reverse radar systems are currently being employed in an increasing number of vehicles and provide important reverse assistance to the driver. However, in practical use, there are also the following complaints and inconveniences. For example, when the background noise is large, the warning tone of the reversing radar is too small and inaudible, or when the background noise is small, the warning tone is too large, which brings uncomfortable feeling to people in the vehicle. In addition, different drivers have different response time habits and different backing vehicle speed habits to the backing radar warning sound, so that people complain about the sound too late and people complain about the sound too early. Since different drivers are not sensitive to the radar warning tone in the vehicle, the driver also complains that the warning tone is too large or too small. Even the same driver sometimes wants to adjust the volume of the reverse radar warning sound in certain specific modes (for example, when a baby or a child is asleep in the car, whether music is played in the car during reverse, whether windows are opened, the environment outside the car is noisy, whether passengers talk aloud in the car, etc.).

The prompting sound of the reversing radar is set by a vehicle manufacturer in the production process at present, and a user cannot personally select the prompting sound after purchasing the vehicle, so that different people are sensitive to the sound and do not respect the preference.

Therefore, it is desirable to provide a reverse sensor system and a motor vehicle, which can overcome the above technical problems in the prior art.

Disclosure of Invention

The invention provides a reversing radar system and a motor vehicle with the reversing radar system, and aims to solve one or more technical problems in the prior art. The reversing radar system according to the invention allows a user to set the size of the reversing radar warning tone and/or the timing of sounding individually, and can intelligently match various user habits and special requirements under different scenes.

One aspect of the present invention relates to a reversing radar system having an alarm device, a control device and a radar detector, the radar detector comprises a transmitter and a receiver, the reversing radar system also comprises a user adjusting module and a background sound sensor arranged in the carriage, the user adjusting module and the background sound sensor are respectively connected with the control device by signals, the user adjusting module also comprises a user interface unit and a storage unit, a user can adjust or set the output parameters of the alarm device through the user interface unit and store the output parameters in the storage unit, the reverse radar system is directly or indirectly connected with a vehicle speed sensor or monitors the reverse vehicle speed through a radar detector, wherein the control device comprises an evaluation unit arranged to determine the output parameters of said warning device in combination at least on the basis of user settings, detection signals of a background sound sensor and the speed of the vehicle in reverse. That is, the output parameters of the warning device are determined synthetically by the evaluation unit at least on the basis of the signal of the background sound sensor, the vehicle speed and the associated user settings. When the vehicle speed and the background sound are both within the preset normal range, the output parameters of the alarm device are consistent with the preset settings of the user. For example, when the vehicle speed is fast, such as greater than a preset threshold, for example greater than 10 Km/h, the volume of the warning alert tone is set to be large and jerky. And when the vehicle speed is low, the volume of the alarm prompt tone is set to be the normal preset volume. Similarly, if the background sound is high, the warning sound volume is correspondingly turned up, whereas a low background sound indicates that the interior of the vehicle is quieter, or that a passenger is at rest, the warning sound volume is correspondingly turned down. Here, "directly or indirectly coupled" means that the reversing radar system is signal-coupled to a vehicle speed sensor or that vehicle speed information can be obtained from a control system of the motor vehicle.

Advantageously, said user interface unit is designed as a button or knob arranged on the steering wheel or the sub-dashboard; or the user interface unit is designed as a graphical interface displayed on a display device, for example designed as a touch screen; or as a speech input unit.

Advantageously, the output parameter of the alarm device is one or more of volume, frequency, timbre, language or content, response time of an alarm prompt tone.

Advantageously, the warning device comprises a first speaker arranged on the left side and a second speaker arranged on the right side, the warning tone on the left side being made greater than the warning tone on the right side when the obstacle closest to the vehicle is located on the left side, and the warning tone on the right side being made greater than the warning tone on the left side when the obstacle closest to the vehicle is located on the right side. Thus, the driver can judge the direction of the obstacle only by the warning sound. This greatly improves safety when parking in cases where the line of sight is obstructed, such as at night or in bad weather.

Advantageously, the reversing radar system is coupled directly or indirectly to a user identification module of the motor vehicle, the user settings are stored in the memory unit in association with the user identification, and the control device can invoke the relevant settings stored in the memory unit in dependence on the user identification. Here, "directly or indirectly coupled" means that the user id module is in communication with the reversing radar system or the reversing radar system can obtain information and data of the user id module from a control system of the motor vehicle. The user identification module is, for example, a common face recognition system, a fingerprint recognition system, or the like.

Advantageously, the background sound sensor is designed, for example, as a sonar sensor for detecting the level of background sound inside the vehicle cabin, in particular around the driver.

Preferably, the reversing radar system is also coupled directly or indirectly to a weather sensor of the motor vehicle. The evaluation unit additionally takes into account the weather conditions when determining the output parameters of the warning device. For example, in the case of a rainy or snowy day, the alarm device is set to be more sensitive and the volume is also set to be larger.

Preferably, the control device further comprises a data recording and analyzing module, which records and stores the settings of the user at different times and under different scenes based on the user identity information, and determines the output parameters of the alarm device by an algorithm, in particular a self-learned AI algorithm. Therefore, intelligent control over the alarm device is realized.

Another aspect of the invention also relates to a motor vehicle having the aforementioned reversing radar system. The variants described for the reversing radar system and the advantageous technical effects thereof are also applicable to such motor vehicles. Here, the description is omitted.

Further characteristics and advantages of the invention are given by the following description of a preferred embodiment with the aid of the drawings.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It is obvious that the described embodiments are only a part of the possible embodiments of the invention, but the invention is not limited thereto.

Fig. 1 shows a block diagram of one possible embodiment of a reversing radar system 100 according to the invention. As shown in fig. 1, the reverse sensor system 100 includes an alarm device 1, a control device 2, a radar detector 3, a user adjustment module 4, and a sonar sensor 5, wherein the alarm device 1 includes a first speaker 11 and a second speaker 12, and the radar detector 3 includes a first detection module 31 disposed on the left rear side and a second detection module 32 disposed on the right rear side. Each radar detector further includes a transmitter and a receiver, respectively. The radar detector 3 is in signal connection with the control device 2. When the detection module of the radar detector 3 detects an obstacle, a signal is sent to the control device 2. The control device 2 drives the loudspeaker of the alarm device 1 to give out an alarm prompt tone based on the signal of the radar detector 3. The alarm device 1 is also at least in signal connection with the control device 2. The control module 2 also has integrated therein an evaluation unit, which may be implemented by software.

The user adjusting module 4 is arranged inside the carriage and is in signal connection with the control module 2. The user adjustment module 4 comprises user interface elements, such as buttons or knobs, arranged on the steering wheel or on the dashboard; or a graphical interface designed to be displayed by means of a display device, in particular a touch screen. It is also conceivable to design the user interface unit as a speech input unit. Through buttons or knobs or through a touch-operated graphical interface and voice input, the user can set one or more of the volume, frequency, timbre, language or content, response time of the alert tone. The content of the alert tone may be a simple drop sound or may be a signal indicating the distance of the vehicle from an obstacle, e.g. 1 meter, 0.5 meter, etc. Obviously, other prompt messages, such as "pay attention to the left rear," "pay attention to the right rear," and so on, are also possible. Similar to navigation systems, the user can also select the timbre, language, for example, in chinese or english in the female voice by means of buttons or knobs or a touch-sensitive graphical interface. After the user setting, the relevant settings may be stored in the storage unit in association with the user identity. The user identity can be identified and verified through the vehicle-mounted user identity identification module. The user identification module is, for example, a common face recognition system or fingerprint recognition system, etc. The reversing radar system 100 is directly or indirectly connected to the user identification module, that is to say the reversing radar system 100 can directly obtain the user identification information from the user identification module or indirectly obtain the user identification information through the motor vehicle control system. Thus, the user's settings and corresponding usage habits may be recorded and stored in association with the user identity. On the one hand, under the condition that a plurality of users use the same vehicle, the originally stored setting can be directly called after the user identity is determined, and repeated setting is avoided. On the other hand, the output parameters of the alarm device can be intelligently recommended or automatically set through an algorithm, particularly a self-learning AI algorithm, based on historical big data by recording the setting conditions of the same user at different time and under different scenes.

The sonar sensor 5 is disposed inside the vehicle compartment for detecting background sounds inside the vehicle compartment. The sonar sensor 5 is preferably disposed in the vicinity of the driver for detecting the magnitude of background sounds around the driver. The evaluation unit determines the output parameters of the alarm device 1 from the signal of the background sound sensor and the associated user settings. That is, the background sound level inside the vehicle cabin is additionally taken into account when determining the output parameters of the warning device 1. If the noise is large, such as playing music in the car when the car is backed, opening the window, and the environment outside the car is noisy or the passengers on the car talk in loud voice, the volume of the prompt tone is increased. And when the baby or the child is asleep in the car, the volume of the prompt sound is reduced.

Fig. 2 shows a motor vehicle 6 equipped with a reversing radar system 100 according to the invention in reversing. The reverse sensor system 100 is provided at the rear of the motor vehicle 6. As shown in fig. 2, an obstacle 7 is present on the rear left side of the motor vehicle 6. In the reverse mode, the first detection module 31 of the radar detector 3, which is arranged on the rear left side, will detect the obstacle 7 and transmit an alarm signal to the control device 2. The evaluation unit of the control device 2 evaluates the alarm signal and, at the same time, takes into account other inputs, for example background sounds, to finally determine the output parameters of the alarm device 1. Here, it is preferable to set the sound volume of the first speaker 11 disposed on the left side of the driver to be large, and the sound volume of the second speaker 12 disposed on the right side of the driver to be turned down, even without emitting sound at all.

Although not shown, the reverse sensor system may also be coupled directly or indirectly to a vehicle speed sensor or monitor the vehicle speed in reverse through a radar detector. The evaluation unit additionally takes the vehicle speed into account when determining the output parameters of the warning device. For example, when the vehicle speed is fast, such as more than 10 Km/h, the volume of the warning alert tone is set to be large and jerky. And when the vehicle speed is low, the volume of the alarm prompt tone is set to be the normal preset volume. Here, "directly or indirectly coupled" means that the reversing radar system is signal-coupled to a vehicle speed sensor or that vehicle speed information can be obtained from a control system of the motor vehicle.

In addition, the reversing radar system is also coupled directly or indirectly to a weather sensor of the motor vehicle. The evaluation unit additionally takes into account the weather conditions when determining the output parameters of the warning device. For example, in the case of a rainy or snowy day, the alarm device is set to be more sensitive and the volume is also set to be larger.

In summary, the invention intelligently adjusts the sound start, the sound size and the sound frequency of the reverse radar prompting sound based on the self-learning AI algorithm by allowing the user to set and automatically identify the data such as background noise, reverse speed, reverse driving habit of the driver and the like in a personalized way, thereby providing the optimal reverse assistance for the driver.
