TABLE 2
Then, the vehicle speed warning score and the obstacle distance warning score are added as warning scores. For example, if the distance between the vehicle and the obstacle is 10m and the vehicle speed is 8km/h, the warning score=3+1=4.
The warning control signal generation module 212 may be configured to compare the determined warning score to a predetermined threshold to generate a different warning control signal based on the received information of the camera (i.e., information indicating the type of obstacle).
According to an embodiment of the present utility model, different predetermined thresholds are set according to the type of obstacle. For example, the first threshold is set to 3, the second threshold is set to 7, and the third threshold is set to 10, but the present utility model is not limited thereto.
According to the alarm system for the vehicle, provided by the embodiment of the utility model, different alarm sounds can be emitted according to the distance between the vehicle and the obstacle and the vehicle speed aiming at different types of obstacles, so that traffic noise generated by disordered horn sounds can be reduced, and an alarm effect can be maintained.
Hereinafter, a control process of the warning system for a vehicle according to an embodiment of the present utility model will be described in detail with reference to fig. 2, taking a configuration of an electric vehicle and an obstacle type as an example of a vehicle or a pedestrian.
When the buzzer button is pressed (S21), the buzzer may be operated directly, i.e., an alarm sound is generated during the time when the buzzer button is pressed. When the horn button is pressed (S22), the tweeter and the woofer may operate simultaneously, i.e., an alarm sound is generated during the time the horn button is pressed.
When the alarm key is pressed (S23), the alarm control device 200 calculates an alarm score from the received information of the wheel speed sensor and the distance detection sensor (S24). In addition, the alarm device may also receive information of the image acquirer (S25), the received information of the image acquirer indicating the type of obstacle, i.e., whether the obstacle is a vehicle or a pedestrian.
When the obstacle is a pedestrian, the alarm control device compares the determined alarm score with a first threshold (e.g., set to 3) (S26), and if the determined alarm score is equal to or less than the first threshold (i.e., no in S26), the alarm control device 200 outputs an alarm control signal to operate the buzzer to sound an alarm in a time when the alarm key is pressed. That is, when the vehicle is traveling at a low speed and the pedestrian approaches the vehicle, the vehicle can make a soft sound to alert the pedestrian.
If the determined alarm score is greater than the first threshold (i.e., yes in S26), the alarm control device further compares the determined alarm score with the second threshold (S27). If the determined alarm score is equal to or less than the second threshold (i.e., no in S27), the alarm control device 200 outputs an alarm control signal that causes the virtual engine wave system to operate, causing the virtual engine wave system to sound an alarm in a time when the alarm key is pressed.
If the determined alarm score is greater than the second threshold (i.e., yes in S27), the determined alarm score is further compared to a third threshold (S28). If the determined alarm score is equal to or less than the third threshold (i.e., no in S28), the alarm control device outputs an alarm control signal for operating the woofer so that the woofer sounds an alarm in a time when the alarm key is pressed.
If the determined alarm score is greater than the third threshold, the alarm control device outputs an alarm control signal for enabling the tweeter and the woofer to operate simultaneously, so that the tweeter and the woofer simultaneously sound an alarm in a time when the alarm key is pressed.
When the obstacle is a vehicle, the alarm control device compares the determined alarm score with a third threshold (S28), and if the determined alarm score is equal to or smaller than the third threshold, outputs an alarm control signal for operating the woofer, and if the determined alarm score is greater than the third threshold, outputs an alarm control signal for operating both the tweeter and the woofer.
The control process of the alarm system for a vehicle according to the embodiment of the utility model is also not limited to the above-described configuration, and for example, different thresholds may be set according to the kind of the obstacle type that can be recognized, thereby outputting different alarm sounds.
According to another embodiment of the present utility model, the input device for the alarm system of the vehicle may further include a double flashing key, and the double flashing key may be electrically connected with the alarm control device. Fig. 3 shows a control procedure of an alarm system for a vehicle including a double flashing key case.
Referring to fig. 3, in case that the alarm key is pressed, the alarm control device may further detect whether the double flashing key is pressed, and if the double flashing key has been pressed (i.e., double flashing operation), the alarm control device outputs an alarm control signal for simultaneously operating the tweeter and the woofer. If the double flash key is not pressed (i.e., the double flash is not operated), the process is performed in accordance with the case that the alarm button is pressed, i.e., the operations of S34 to S38 are similar to those of S24 to S28, and will not be repeated here.
According to the control process of the alarm system for the vehicle, according to the embodiment of the utility model, different alarm sounds can be sent out according to the distance between the vehicle and the obstacle and the vehicle speed aiming at different types of obstacles, so that traffic noise generated by the disorder of horn sounds can be reduced, and the alarm effect can be maintained.
The various embodiments of the utility model are not an exhaustive list of all possible combinations, but are intended to describe representative aspects of the utility model and the disclosure described in the various embodiments can be applied separately or in combinations of two or more.
