Automobile whistling intra-automobile reminding device and control method

Abstract

The invention discloses an automobile whistling intra-automobile reminding device and a control method. The device is simple in structure, low in manufacturing cost and high in practicability. Sound pickup devices need to be arranged in multiple positions outside an automobile body and are subjected to wind noise resistance treatment, and a data acquisition result is prevented from being affectedby wind noise generated in the automobile traveling process. Display areas are arranged in the positions of an automobile instrument, a center control screen or rearview mirrors and used for sending vision reminding signals. The reminding device is interconnected with an automobile sound system, so that a sound reminder is sent out. By the adoption of the automobile whistling intra-automobile reminding device and a control strategy and through the cooperative effect of all components, plenty of cost is saved, and the device and the control strategy are suitable for being used and popularized.

Description

technical field [0001] The invention relates to a device and a control strategy, in particular to a car siren warning device and a control method in the car, belonging to the technical field of car applications. Background technique [0002] With the improvement of vehicle manufacturing technology and the comfort requirements of drivers and passengers in recent years, the attention and R&D investment of newly developed passenger vehicles on NVH have reached unprecedented heights. As the NVH of vehicles is getting better and better, the cabin The ability to isolate external noise is getting stronger and stronger. While providing a quiet driving environment for drivers and passengers, it also isolates the sound of vehicle horns from the outside of the car.

[0002] With the improvement of vehicle manufacturing technology and the comfort requirements of drivers and passengers in recent years, the attention and R&D investment of newly developed passenger vehicles on NVH have reached unprecedented heights. As the NVH of vehicles is getting better and better, the cabin The ability to isolate external noise is getting stronger and stronger. While providing a quiet driving environment for drivers and passengers, it also isolates the sound of vehicle horns from the outside of the car. The sound is not easy to be noticed, it cannot play the role of reminding the driver, and it is easy to cause safety accidents. Secondly, traditional vehicles do not have the function of actively identifying the direction of the sound of the whistle, causing the driver to be unable to recognize the whistle vehicle at the first time, that is: when driving After the driver hears the whistle, it is impossible to tell whether it is the left, right or rear vehicle whistle at the first time, which may easily cause the driver to misjudge and cause safety hazards. Commercial vehicles, buses, and special vehicles are generally large in size and The noise is high and the blind spot is large, and the driver is less likely to hear the whistle when operating this type of vehicle than a small passenger car. In order to eliminate the above-mentioned hidden dangers in the car, the present invention proposes a sensor that receives signals from the car through pickups and other sensors. The sound signals from different positions outside the car are filtered, identified, processed, and converted into sounds, images, and indicator light signals inside the car that are easily noticed by the driver, so that the driver can accurately know the warning reminder outside the car at the first time and make a correct judgment And take measures to improve driving safety. At present, all cars are not equipped with similar devices. The warning signal outside the vehicle, such as the sound of the whistle, enters the car through the sound transmission. However, with the development of car manufacturing technology and users put forward higher requirements for vehicles Comfort requirements, the NVH of the vehicle is getting better and better, and the ability of the cabin to isolate external noise is getting stronger and stronger. While providing a quiet driving environment for the driver and passengers, it also isolates the sound of the vehicle's whistle from the outside of the car, causing certain noise. potential safety hazard, therefore, a warning device and control method in the car whistle will have a good market prospect
