A method for monitoring an automobile based on a satellite, and a vehicle-mounted computer are provided. The method includes: acquiring first information of the automobile; sending the first information to the satellite through a satellite data transfer unit (DTU); and receiving and displaying second information from a cloud monitoring platform.

A method for estimating the overall wear of a tyre having a crown, the crown comprising a tread having a mean thickness E, the tyre delimiting an internal cavity, comprises the following steps: acquiring a transfer function F of the tyre on a reference ground depending on influencing factors and the thickness E; acquiring a passage function β of the mounted assembly, said passage function being defined for a section of road;
in a measurement cycle determining a force F.sub.X and a rate of slip g % at the wheel centre of the tyre, when running in a straight line involving variations in acceleration on the dry section of road; determining a load Z1 experienced by the mounted assembly; determining a temperature T1 of the mounted assembly; determining an inflation pressure P1 of the internal cavity.

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 transmitted from a trigger device. 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 the transmitter, 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, a controlling section, which is configured to perform response transmission, by which the signal is transmitted to the transmitting section in response to the unmodulated wave, when the trigger receiving section receives the unmodulated wave, and a memory section, which is configured to store at least one of reception time of the unmodulated wave and a number of times of the response transmission.

Received acceleration or motion information are analyzed and when the analysis of this information indicates that motion or acceleration is detected, received burst patterns from the other sensors are analyzed. Based upon analyzing the detected burst patterns from the other sensors, a first burst pattern is selectively altered to transmit according to a single communication format, the single format being for a single vehicle manufacturer.

A method for automatic adjustment of the performance of a vehicle may include detecting at least one significant physical quantity for checking the performance of the vehicle; defining at least one pair of reference indicators correlated with that physical quantity; saving at least one value of a said reference indicator in a predetermined nominal reference condition; detecting at least one value of a said reference indicator in a real operating condition of the vehicle; comparing said nominal reference indicator and real reference indicator and, if their values are different from each other, and implementing a correction of the driving power of the vehicle to compensate for the difference ascertained.
