Publication number: 20210116289Abstract: Various embodiments include a system for determining a filling level of a fluid comprising: a fluid container with a first wall, a second wall opposite the first, and a bottom; a transducer mounted outside the first wall at a predetermined distance from the bottom, the transducer transmitting an ultrasonic signal through the first side wall into the fluid container; a reflection element inside the fluid container reflecting the signal back to the transducer; and a control device for activating the transducer. The control device identifies a current fluid filling level greater than a minimum filling level if the signal received by the transducer is an ultrasonic signal reflected by the reflection element, and identifies a fluid filling level less than the minimum filling level if the transducer does not receive an ultrasonic signal or receives an ultrasonic signal reflected by the first side wall.Type: ApplicationFiled: October 12, 2020Publication date: April 22, 2021Applicant: Vitesco Technologies Germany GmbHInventors: Karl-Friedrich Pfeiffer, Wighard Jäger

Patent number: 10444057Abstract: The present disclosure relates to a device for determining a height of a fluid surface in a fluid container. In some embodiments, the device comprises: a first sound transducer and a second sound transducer for transmitting and receiving sound signals; a reference element disposed at a predetermined distance from the second sound transducer in a fluid space of the fluid container; a deflection element in the fluid space to deflect sound signals by a predetermined angle in the direction of the reference element; and a control unit. The two sound transducers are adjacent a base portion of the fluid container and aligned similarly. The control unit is configured to establish a speed of sound within a fluid in the fluid space based at least in part on travel of the second sound signals and thereby to establish the height of the fluid surface over the base portion of the fluid container dependent on the first sound signals and the speed of sound within the fluid.Type: GrantFiled: May 26, 2015Date of Patent: October 15, 2019Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Karl-Friedrich Pfeiffer, Claus Weber, Henning Grotevent, Wighard Jaeger

Patent number: 10101193Abstract: A fluid level sensor may include a first sound transducer, a second sound transducer, a reference element, a first deflection element, and a control unit. The reference element may be disposed at a predetermined distance from the second sound transducer and arranged in a fluid space of the fluid container. The first deflection element may be arranged in the fluid space to deflect the second sound signals by a first predetermined angle toward the fluid surface. The control unit may establish a speed of sound within a fluid in the fluid space based at least in part on the second sound signals and establish the level of the fluid surface over a base portion of the fluid container based at least in part on the first sound signals, the second sound signals, and the speed of sound within the fluid.Type: GrantFiled: May 26, 2015Date of Patent: October 16, 2018Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Karl-Friedrich Pfeiffer, Claus Webber, Henning Grotevent, Wighard Jaeger

Patent number: 9719833Abstract: A filling level transmitter for measuring a filing level of a liquid includes: a filling level sensor having: an ultrasonic transceiver configured to emit ultrasound, and sensor electronics; a sound-conducting tube having two reflectors spaced apart from one another, the first reflector being configured to deflect ultrasound emitted by the transceiver in the direction of the second reflector, and the second reflector being configured to deflect the emitted ultrasound in the direction of the surface of the liquid. A third reflector is arranged in the second reflector such that emitted ultrasound impacting the third reflector is reflected in the direction of the first reflector.Type: GrantFiled: December 20, 2012Date of Patent: August 1, 2017Assignee: Continental Automotive GmbHInventors: Wighard Jäger, Karl-Friedrich Pfeiffer

Publication number: 20170160126Abstract: The present disclosure relates to sensors, and the teaching may be applied to a device for determining a speed of a sound signal in a fluid in a fluid container. A device may include: a sound transducer for transmitting and receiving sound; a first reflector element and a second reflector element integrally formed in a reference element to reflect sound generated by the sound transducer back to the sound transducer; and a control unit operating to: ascertain a first signal runtime related to a first reflection of the sound signal from the first reflector element; a second signal runtime related to of a second reflection of the sound signal from the second reflector element; and calculate the speed as a function of the two.Type: ApplicationFiled: July 6, 2015Publication date: June 8, 2017Applicant: Continental Automotive GmbHInventors: Karl-Friedrich Pfeiffer, Claus Weber, Henning Grotevent, Wighard Jaeger
