A vehicle and motorbike monitoring system and apparatus thereof are provided, including a monitoring apparatus, a computer, and a mobile device. The monitoring apparatus is connected with the computer to exchange information through a communication protocol therewith. The computer sends a status signal based on the equipment status of the vehicle/motorbike to the monitoring apparatus and sends a status information to the mobile device based on the status signal, such that the owner of the vehicle/motorbike know the equipment status. The owner sends a command information to the monitoring apparatus through the mobile device, and the monitoring apparatus subsequently sends a controlling signal to the computer, such that the equipment status changes. Therefore, safety and convenience of usage are enhanced.

A transmitter is configured to be attached to each of wheel assemblies provided in a vehicle and execute a process in accordance with a command included in a trigger signal. The transmitter includes a battery, which serves as a power source for the transmitter, a condition detecting section, which is configured to detect a condition of a tire, a trigger receiving section, which is configured to receive, as the trigger signal, an unmodulated wave having a received signal strength indication greater than or equal to a predetermined received signal strength indication, a transmitting section, which is configured to transmit a signal, and a controlling section, which is configured such that, when the trigger receiving section receives the unmodulated wave, the controlling section causes the transmitting section to transmit the signal in response to the unmodulated wave. The controlling section is configured to execute an accumulation process to accumulate reception time of the unmodulated wave from a starting point in time, and shift into a restriction state to restrict a response to the unmodulated wave when the accumulated reception time reaches a predetermined time.

A tire condition detecting apparatus includes a transmitting section, a receiving section, a control section, a property detecting section, and a battery, which is a power source for the apparatus. The control section operates in a control mode that is selected from a normal mode and a power saving mode. In the power saving mode, power consumption associated with reception of the wirelessly transmitted signal from the external device is less than that in the normal mode. When the amount of change in the electrical property of a valve stem detected by the property detecting section exceeds a reference change amount, the control section switches the control mode to the normal mode. The control section also switches the control mode to the power saving mode when a termination condition is met in the normal mode

A tire air pressure detection device includes a plurality of transceivers and a receiver. The plurality of transceivers are correspondingly provided in a plurality of wheels of a vehicle. Each wheel has a tire. The receiver is attached to a vehicle body. Each of the plurality of transceivers outputs a detection signal indicative of an air pressure of the tire of the corresponding wheel. Each of the plurality of transceivers processes the detection signal, and generates a frame storing the processed detection signal as data related to the air pressure of the tire. The receiver receives the frame. The receiver detects the air pressure of the tire based on the data stored in the received frame.

A method of determining a status of a tyre monitoring device that includes a power supply. The method includes determining a value indicative of consumption of the power supply, determining a status of the tyre monitoring device based on the value indicative of consumption of the power supply, and providing an indication based on the determined status.

A pneumatic tire includes a first tread area portion, an electric power source, a transmission device, an accelerometer, and a control unit configured to operate in a power saving mode and a normal mode. A contact of the first tread area portion with a surface is detected by sensing acceleration of the first tread area portion by the accelerometer. The control unit is configured to switch from the normal mode to the power saving mode after a detection that the first tread area portion is on a contact patch of the tire. The control unit is configured to switch from the power saving mode to the normal mode when a first specified time depending on the rotation speed of the tire has elapsed since the detection that the first tread area portion is on the contact patch. A monitoring method and a system are used with the pneumatic tire.

A method for controlling an electronic valve for a tire of a motor vehicle including an electronic assembly of sensors and a bidirectional radiofrequency communication assembly, connected to the electronic assembly of sensors. This method is noteworthy in that: in a parked situation and in the effective absence of a user, the electronic assembly of sensors is kept dormant and the communication assembly is kept on standby, and on the arrival of a user, the electronic assembly of sensors is activated by the communication assembly.

A system for assessing operating conditions for a vehicle includes. a power source and first and second sensors coupled to the power source and configured to generate corresponding first and second sensor signals indicative of first and second operating conditions of the vehicle. The second operating condition is indicative of an operating state of the vehicle. A transmitter is coupled to the power source and configured to transmit an informational signal responsive to the first sensor signal. A controller is configured to receive the second sensor signal, determine, responsive to the second sensor signal, whether the operating state of the vehicle meets a predetermined condition and then provide control signals to one or both of the first sensor and the transmitter to control the sampling rate of the first sensor and/or the transmission rate of the transmitter depending on whether the operating state meets the predetermined condition.
