A method for localizing tire sensors includes determining a wake up field power, transmitting an LF wake up field having the wake up field power from an LF antenna on the vehicle, receiving an identification signal from each tire sensor awakened by the transmitted LF wake up field, and determining whether a desired number of tire sensors have woken up in response to the transmitted LF wake up field based on the received identification signals. When the desired number of tire sensors have woken up, the method can further include recording the identification signals received from the awakened tire sensors and the respective antennas that awoke the respective tire sensors. The method further includes determining whether a desired number of antennas have transmitted a respective LF wake up field. When the desired number of antennas have transmitted a respective LF wake up field, the method can further include comparing the received identification signals and determining locations for the tire sensors based on which respective antenna woke up which respective tire sensor and whether the received identification signals match other received identification signals.

Recognizing tire sensor location in factory mode for TPMS and smart entry system

A vehicle entry/tire pressure monitoring system for a vehicle includes an ECU, LF antennas mounted on the vehicle and being in communication with the ECU, and tire sensors mounted in, on or adjacent respective tires of the vehicle. Each LF antenna is configured to transmit an LF tire sensor wake up field and a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle tire sensor. Each tire sensor includes a two-axis receiver antenna and an RF transmitter configured to transmit an RF signal. Each two-axis receiver antenna is configured such that a first axis of the two-axis antenna is configured to detect a respective LF field transmitted by one of the LF antennas and a second axis of the two-axis antenna is configured to detect a respective LF field transmitted by another of the LF antennas.

Two axis antenna for TPMS sensor

A vehicle system includes a plurality of tire sensors, a plurality of low frequency ('LF') antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals. The ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal.

Memorizing location of tires in TPMS and smart entry system

A battery mounting arrangement for a vehicle includes a compartment (e.g., an engine compartment), a cover disposed over the compartment (e.g., a hood disposed over an engine compartment) and a spring mounted set plate mounted to the cover for applying a hold down force on an associated battery mounted in the compartment.

Hood mounted battery set plate

A vehicle entry/tire pressure management system includes a plurality of tire sensors, a plurality of low frequency ('LF') antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. Some antennas can also be configured to transmit a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals.

Localization of tire for TPMS and smart entry system

A tire pressure monitoring system includes tire sensors mounted in, on or adjacent respective tires of the vehicle, LF antennas mounted on the vehicle, and an ECU. Each tire sensor is configured to transmit an RF signal and to detect an LF field. Each antenna is configured to transmit an LF field to wake up the tire sensors. The ECU is in communication with the antenna, the tire sensors and a radio configured to receive AM broadcast signals. The ECU can communicate with the radio to inhibit speakers in communication with the radio from emitting sound while each LF field to wake up the tire sensors is being transmitted.

Radio system adjustment with TPMS and smart entry system

A vehicle entry/tire pressure management system includes an ECU, tire sensors mounted in, on or adjacent respective tires of the vehicle, a portable transmission/reception unit configured to be carried by an operator of the vehicle, and an antenna mounted on the vehicle and in communication with the ECU. Each tire sensor is configured to transmit an RF signal. The portable transmission/reception unit can transmit RF signals for controlling operations of the vehicle including unlocking doors of the vehicle. The antenna is configured to transmit an LF tire sensor wake up field to wake up the tire sensors. The tire sensor wake up field includes a unique header format. The tire sensors only fully wake up upon receiving the unique header format.
