Title:
VEHICLE SOUND PROMPT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/068436
Kind Code:
A1
Abstract:
A vehicle sound prompt system, comprising: a person detection module (10), a distance detection module (40), a control module (20), and a sound prompt module (30). The control module (20) uses a CAN mainline to form communication connections with the person detection module (10), the distance detection module (40), and the sound prompt module (30). The person detection module (10) is used for detecting the presence of a person outside a vehicle, and for sending, when a person is detected, a trigger signal to the distance detection module (40). The distance detection module (40) starts detecting, after receiving the trigger signal, the distance between the person outside the vehicle and the vehicle, and sends, when the distance detected is less than a pre-configured range, a control signal to the control module (20). The control module (20) sends, after receiving the control signal, an implementation signal to the sound prompt module (30) such that the sound prompt module (30) issues a sound prompt according to the implementation signal. The system can actively issue a sound prompt to a person outside a vehicle when the vehicle approaches, thereby reducing the risk of a traffic accident.
