Abstract
A tire monitoring system and associated method is disclosed. The tire monitoring system includes a plurality of tire sensor modules configured to transmit tire data in a wireless fashion at a predetermined time interval. The system also includes a vehicle control module that is configured to receive the tire data from the tire sensor modules, and is further configured to dictate the predetermined time interval at which the tire data is transmitted by the tire sensor modules.
Claims41
A tire monitoring system, comprising:
- a tire sensor module configured to transmit tire data in a wireless fashion at a predetermined time interval;
- and
- a vehicle control module configured to receive the tire data from the tire sensor module, and further configured to dictate the predetermined time interval at which the tire data is transmitted by the tire sensor module.
A multi-mode tire monitoring system associated with a vehicle, comprising:
- a plurality of tire sensor modules, each tire sensor module comprising:
- a battery;
- a tire parameter sensor coupled to the battery;
- a tire sensor controller coupled to the battery and having a clock circuit associated therewith;
- a transceiver coupled to the battery;
- and
- a vehicle control module operably associated with the plurality of tire sensor modules,
- wherein in a factory mode of operation each of the tire sensor modules are in a low current mode of operation, and wherein each of the tire sensor modules are further configured to exit the low current mode of operation based on a wake-up command transmitted thereto from the vehicle control module.
A tire monitoring system, comprising:
- a means for acquiring tire data and transmitting the tire data in a wireless fashion associated with each tire of a vehicle;
- and
- means for receiving the transmitted tire data and dictating a unique predetermined time interval in which tire data associated with each tire is transmitted by the tire data acquisition and transmission means, wherein the predetermined time intervals do not overlap in time with one another.
A method of transmitting tire data from a plurality of tire sensor modules to a vehicle control module, comprising:
- assigning a predetermined time interval for transmission of the tire data to each of the tire sensor modules, wherein each of the predetermined time intervals do not overlap with one another in time;
- and
- transmitting tire data from each tire sensor module to the vehicle control module during the respective predetermined time interval, thereby avoiding data collisions associated with the tire data at the vehicle control module.
A method of configuring a tire data acquisition system, comprising:
- maintaining each of a plurality of tire sensor modules in a low power condition in a factory mode of operation;
- and
- activating the plurality of tire sensor modules in a learn mode of operation by transmission of a wake-up command from a vehicle control module.
A method of collecting tire data at a vehicle control module from a plurality of tire sensor modules associated with tires of a vehicle, comprising:
- identifying a tire location of each of the tire sensor modules;
- assigning a unique predetermined time interval to each of the identified tire sensor modules, wherein the respective predetermined time intervals do not overlap in time;
- and
- transmitting tire data from a respective tire sensor module to the vehicle control module during each respective predetermined time interval, thereby avoiding tire data collisions at the vehicle control module.
