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 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.
