Definitions
- the present invention is directed generally to a device for alerting the driver of a rearwardly moving vehicle to the presence of any object in close range behind the vehicle. More particularly, the present invention is directed to a micro-wave radar device using the doppler shift principle to detect the presence of a moving target within the transceiver range.
- Devices have previously been known for detecting the presence of objects behind a vehicle but such devices have not achieved widespread usage. Devices which provide an audible alarm directed rearwardly of the vehicle are ineffective if a child, for example, in the path of the vehicle does not react to the alarm and if the vehicle driver does not hear the alarm. Certainly an external alarm will not remove objects from the path of the vehicle.
- an object of the invention is to provide an improved device for alerting the driver of a rearwardly moving vehicle to the presence of a person or object within a short range distance behind the vehicle.
- Another object is to provide such a device with a remote audible alarm suitable for placement within the passenger compartment of a vehicle.
- Another object is to provide such a device which employs micro-wave radar technology.
- Another object is to provide a driver alerting device which may be easily electrically and mechanically connected to a vehicle.
- an object is to provide a driver alerting device which is economically to manufacture, simple and rugged in construction and efficient in operation.
- the driver alerting device o the present invention includes a transceiver adapted for mounting at the rearward end of a vehicle for directing its wave output rearwardly of the vehicle. Return wave signals from any object within the short transceiver range behind the vehicle are supplied to the transceiver through an antenna connection. Any resultant doppler shift signal is amplified for driving the audio alarm.
- the circuit of the device is adapted for electrical connection to the back-up light circuit of a vehicle for activation only when the vehicle transmission is engaged in reverse gear.
- the driver alerting device thus immediately sounds an alarm when any moving or stationary object is detected within the short transceiver range behind a rearwardly moving vehicle on which it is installed. Even when the vehicle is stationary, but with the back-up lights activated, the device will signal the presence of any moving object within the transceiver range. Because the device operates by micro-wave radar, it is unaffected by noise, light, or weather-conditions such as snow, rain, heat and cold.
- FIG. 1 is a diagrammatic top plan view of the driver alerting device installed on a vehicle
- FIG. 2 is an electrical schematic circuit diagram of the driver alerting device; .[.and.].
- FIG. 2A is an electrical schematic circuit diagram of the driver alerting device.
- FIG. 3 is a perspective view of the transceiver housing of the device.
- the driver alerting device of the present invention is indicated generally at 10 in FIG. 1 installed on the rear bumper 12 of a truck 14 having a passenger compartment 16 situated forwardly of box 18.
- Device 10 operates by micro-wave radar using the doppler shift principle to detect the presence of a moving target within the transceiver range.
- the operating elements of the device 10 are wholly electronic and are shown in .[.FIG. 2.]. .Iadd.FIG. 2A .Iaddend.as including a transceiver 20, an antenna 22, an intermediate frequency amplifier 24 and an audio alarm 26.
- the transceiver 20 includes a gun diode 28 mounted in a wave guide cavity which acts as the transmitter and local oscillator, together with a schottky barrier mixer diode 30 for the receiver. Electromagnetic radiation transmitted from the gunn diode 28 is reflected back at the antenna by any object within the transceiver range. If that object is moving relative to the vehicle, the frequency shift of the wave reflected by the moving object is measured electronically and triggers activation of the alarm 26.
- output frequency of the transceiver 20 is factory preset at 10.525 GIGA HERTZ. Power output is 5 milliwatts minimum. Operating voltage is 8 volts D.C. The resultant doppler frequency obtained is 31.39 HERTZ for each mile per hour of radio velocity.
- the transceiver is unaffected by the presence of magnetic fields, noise, light and varying weather conditions.
- Antenna 22 may be provided as either a high gain antenna or low gain antenna.
- the high gain antenna is preferred for application with 1/4 ton, 1/2 ton and 1 ton vehicles measuring 80 inches maximum in width.
- the low gain antenna is preferred on 1 ton and larger vehicles measuring 80 inches and greater in width.
- the range of the antennas is adjustable and my be user set to accommodate virtually any vehicle. This adjustment is incorporated in the intermediate frequency amplifier 24 and is accessible from the outside of the unit.
- Antenna 22 is preferably constructed of machined aluminum and is also preferably flange-mounted directly to the transceiver 20, thus eliminating the effects of noise and spurious response. Lines 32 in FIG. 1 illustrate an example of a typically adjusted wave pattern.
- the intermediate frequency amplifier 24 is a solid state, multi-stage operational amplifier designed to amplify and shape the resultant doppler shift signal.
- the circuitry is card mounted and has built-in range and sensitivity controls.
- the amplifier is designed to interface with the existing reverse switch 34 (.[.FIG. 2.]. .Iadd.FIG. 2A .Iaddend.) in order to activate the circuit only during reverse operation of the vehicle.
- Reverse switch 34 is typically associated with the vehicle transmission and is incorporated into the back-up light circuit of the vehicle for illuminating the back-up lights whenever the vehicle transmission is engaged in reverse gear.
- the audio alarm 26 is mounted interiorly of the passenger compartment 16 so as to be readily audible to the driver of the vehicle.
- Amplifier 24 drives both the audio alarm 26 and a light emitting diode mounted on the unit.
- the purpose of the light emitting diode is to aid in the adjustment of the unit in the event that the alarm is not audible to the one adjusting the unit at the rearward end of the vehicle.
- the transceiver 20 is shown in FIG. 3 as including a housing 36 which is diagonally sectioned to provide a pivotal top cover 38.
- the wave output from the transceiver 20 is transmitted outwardly through a rearwardly protruding channel section 40 on the rear wall of housing 36.
- a mounting flange 42 extends downwardly from the housing for ready attachment to a vehicle bumper or the like.
- the circuitry is card mounted and all components ar treated with a conformal coating to prevent the effects of moisture and salt. Electrical hook-up to the vehicle is achieved via a splash-proof four circuit connector mounted on the side of the unit. One of the four leads is connected to the vehicle ignition switch, one to the back-up lights or reverse switch 34 on the transmission, one to ground 44 and one to the alarm 26.
- the audio alarm is preferably a solid state piezoelectric alarm capable of developing 80 decibels at 12 volts D.C.
- the transceiver 20 is activated to transmit electromagnetic radiation whenever the vehicle ignition is on and the transmission is engaged in reverse gear. This closes the vehicle reverse switch 34 for illuminating the vehicle backup lights.
- a reducer may be provided between the transceiver 20 and reverse switch 34 to adjust the operating voltage to 8 volts D.C.
- the transceiver range spans the width of the vehicle 14 and extends rearwardly approximately 6 to 12 feet. The maximum range would be approximately 20 feet.
