Abstract
Disclosed is a front obstacle alerting system comprising an obstacle-side signal emitting device and a vehicle-side alerting device, wherein the obstacle-side signal emitting device is a signal emitting element of a front obstacle and emits a directional ultrasonic wave toward a rear side of the front obstacle, and the vehicle-side alerting device is disposed in or on a vehicle and correspondingly outputs an alerting signal according to the directional ultrasonic wave received from a front side of the vehicle.
Claims7
A front obstacle alerting system which alerts for a front obstacle existing in front of a vehicle, comprising:
- an obstacle-side signal emitting device, which is a signal emitting element of the front obstacle, the obstacle-side signal emitting device including a signal generator and a directional speaker, the signal generator being connected to the directional speaker, wherein the signal generator is configured to enable the directional speaker to actively emit, in a directional propagating manner, a directional ultrasonic wave containing an obstacle presence signal toward rear side of the front obstacle;
- and
- a vehicle-side alerting device, which is disposed in or on the vehicle, the vehicle-side alerting device including an ultrasonic receiver, a signal analyzer and a front obstacle alarm, wherein the ultrasonic receiver is arranged facing front side of the vehicle to receive the directional ultrasonic wave transmitting from the front side of the vehicle, the signal analyzer is connected to the ultrasonic receiver and is configured to analyze and determine whether the directional ultrasonic wave received by the ultrasonic receiver contains the obstacle presence signal or not, the front obstacle alarm is connected to the signal analyzer and is configured to output an alerting signal when the directional ultrasonic wave received by the ultrasonic receiver contains the obstacle presence signal.
