  2. Tire-pressure monitoring system - Wikipedia

    en.wikipedia.org/wiki/Tire-pressure_monitoring...

    To save energy and prolong battery life, many dTPMS sensors do not transmit information when parked (which eliminates spare tire monitoring) or apply a more power-expensive two-way communication which enables wake-up of the sensor. For OEM auto dTPMS units to work properly, they need to recognize the sensor positions and must ignore the signals ...

  3. Parking sensor - Wikipedia

    en.wikipedia.org/wiki/Parking_sensor

    The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops.

  4. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    Using the O2 sensor signal, the ECU can operate the engine with an air–fuel ratio very close to 14.7:1, which is the ideal operating mixture for a three way catalyst to be effective. [3] Robert Bosch GmbH introduced the first automotive lambda sensor in 1976, [2] and it was first used by Volvo and Saab in that year. The sensors were ...

  5. Direct TPMS - Wikipedia

    en.wikipedia.org/wiki/Direct_TPMS

    direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers. [1]

  7. MAP sensor - Wikipedia

    en.wikipedia.org/wiki/MAP_sensor

    MAP sensor data can be converted to air mass data by using a second variable coming from an IAT Sensor (intake air temperature sensor). This is called the speed-density method. Engine speed (RPM) is also used to determine where on a look up table to determine fuelling, hence speed-density (engine speed / air density).

  8. Rain sensor - Wikipedia

    en.wikipedia.org/wiki/Rain_sensor

    Rain sensor on the windshield of a car. A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall.

  9. Lane departure warning system - Wikipedia

    en.wikipedia.org/wiki/Lane_departure_warning_system

    Lane assist camera of VW Golf Mobileye's PCB and camera sensor from a Hyundai Lane Guidance camera module. Lane warning/keeping systems are based on: Video sensors in the visual domain (mounted behind the windshield, typically integrated beside the rear mirror) Laser sensors (mounted on the front of the vehicle)
