摘要:
A pressure monitoring system (12) for a tire (14a) of an automotive vehicle includes a first pressure sensor (94) coupled to the wheel, a pressure transmitter (90) coupled to the pressure sensor (94) whereby the transmitter generates a pressure signal. A controller (22) is coupled to the pressure transmitter. The controller (22) receives the pressure signal and in a first stage, compares the pressure signal to a pressure threshold to obtain a sensor status. In a second stage, the controller (22) qualifies the sensor status signal by generating a warning status in response to the sensor status.
摘要:
A tire pressure monitoring system (12) for a vehicle (10) has a plurality of tires (14a-d) in respective rolling locations having a respective plurality of tire transmitters (16a-d) that generate a respective plurality of transmitter identification signals. A controller (22) is coupled to a counter that counts ignition cycle transitions. The controller enters a learn mode in response to the count and the brake condition signal. The system may also include a display for signaling the vehicle operator to perform a desired action. The controller generates a plurality of display signals on the display indicative of the respective plurality of tire locations and activates a timer when the plurality of transmitter identification signals are received before a predetermined time is counted by the timer.
摘要:
A tire pressure monitoring system (12) for a vehicle (10) has a plurality of tires (14a, b, c and d) in respective rolling locations and a spare tire (14e) generating a spare tire identification. A controller (22) starts the timer (44) and sets a tire status to a rolling status, a pending rolling status, a spare status or a pending spare status in response to the timer and the vehicle speed. The controller (22) stores the status and the spare tire identification in the memory.
摘要:
A system (10) and method is provided for calibrating a tire pressure monitoring system using an EM transmitter (14). The present invention includes a first pressure sensor coupled to a wheel of an automotive vehicle (12). The EM pressure transmitter (14) is coupled to the pressure sensor (32). The transmitter (14) has a serial number associated therewith. An EM calibration device has a transmitting range. The EM transmitter device has an actuator. When the actuator is activated, a calibration signal (34) is transmitted within the transmitting range. The calibration signal causes the EM pressure transmitter (32) to transmit a serial number. A controller (16) is EM coupled to the pressure transmitter. The controller (16) receives the serial number and associates the serial number with a tire location of the vehicle.

In at least one embodiment, an apparatus for providing a space management alert for a host vehicle is provided. The apparatus comprises a controller configured to determine whether a first vehicle positioned ahead of the host vehicle is in a first detection zone and to determine whether a second vehicle positioned on one of a left side and a right side of the host vehicle is in a second detection zone. The controller is further configured to determine that the host vehicle is in a high density traffic condition (HDTC) if the first vehicle is in the first detection zone and the second vehicle is in the second detection zone and to selectively disable a space management alert when the host vehicle is in the HDTC.
摘要:
A system and method that, upon connection of a trailer to a tow vehicle, a trailer brake controller informs a tire pressure monitoring system to begin monitoring information at the TPMS and at the same time, activates the initiators, i.e., the electromagnets. Sensors respond to the electromagnetic field that is generated by electric brake magnets. As a result, the sensors transmit RF signals that are received by the tire pressure monitoring system. Transmissions from the sensors are decoded in a controller and processed as necessary for tire pressure monitoring automatically calibrated to the tire pressure monitoring system and the system can request the pressure data from the sensors by way of the low frequency field generated by the electric brakes.

A system and method that, upon connection of a trailer to a tow vehicle, recognizes the trailer and applies a stored trailer configuration in a controller. In one embodiment, tire pressure sensors transmit RF signals that are received by the tire pressure monitoring system. Transmissions from the sensors are decoded in a controller and processed to identify, or create a particular trailer configuration as well as implement tire pressure monitoring automatically calibrated to the particular trailer configuration based on the sensor identifications for the tire pressure sensors. In another embodiment, the trailer configuration includes a pulse width modulated gain control for the trailer brakes.
