Abstract

A distance measuring sensor for mounting on a vehicle has an ultrasound sensing unit 21, a microwave sensing unit 22, a controller 24 and an alarm 23. If the controller receives a sensing signal from either the ultrasound unit or the microwave unit, the controller outputs an alarm signal to alert the driver. The microwave unit detects objects in the long range and the ultrasonic unit detects objects in the close range; if a sensing signal is generated by both units then the distance measured by both units may be compared and the lesser value taken to be the distance to the object. The ultrasound unit may be a plurality of transducers 210 operated sequentially. The controller may be connected to the vehicles central locking system 30 in order to prevent a door being opened if an object is detected moving at a speed equal to or above a predetermined safe speed relative to the vehicle.

Description

technical field [0001] The invention relates to a warning device, in particular to a vehicle distance measuring warning device. Background technique [0002] A car is a convenient means of transportation, and most cars are equipped with a reversing warning device at present. The reversing warning device mainly includes at least one ultrasonic sensor, an alarm and a controller. [0003] The ultrasonic sensor is set at the rear of the car and emits an ultrasonic detection signal with a fixed frequency (such as 40KHz-60KHz). When the ultrasonic detection signal hits an external object (such as a pedestrian or other vehicle, etc.), an echo will be formed. Signal. The siren may be provided in the driver's seat. [0004] The controller is electrically connected to the ultrasonic sensor and the alarm, and the controller presets a threshold distance. The controller calculates the distance between the car and the external object according to the time difference between the ultraso...
