A vehicle has a frame, at least one front wheel, at least one front suspension assembly, at least one rear wheel, and at least one rear suspension assembly, a seat, a steering assembly, an engine, and an air intake system fluidly communicating with the engine. At least one of the front and rear suspension assemblies includes an air spring. An air compressor selectively supplies air to the at least one air spring. An inlet of the air compressor fluidly communicates with the air intake system. During operation of the air compressor to supply air to the at least one air spring, the air compressor draws air from the air intake system and simultaneously supplies the air to the at least one air spring. A control unit is electrically connected to the air compressor for controlling an operation of the air compressor.

The present invention relates to a continuous monitoring system for shock absorbers, for use in motor vehicles or in any kind of machine which requires them, which will enable the shock absorbers to be evaluated during normal operation. It is essentially characterised by all the necessary components being embedded into the shock absorber itself, in a single circuit 1 or several integrated interconnected circuits, which are equipped with means of identification which provide the vehicle's or machine's various electronic management systems with the necessary information regarding shock absorbers identification, characteristics and capacity for self-diagnosis. The aforementioned components include acceleration, pressure and temperature sensors 2, signal conditioning and processing circuits 3, a wireless communication system 4, power production 5 and storage system 7 and management electronics 6.

摘要:
A method and a device for detecting critical driving conditions of a vehicle are provided, in which instantaneous values of a variable describing the transverse dynamics are measured, and a critical driving condition is detected by evaluating the time characteristic of the ascertained values. In order to detect a critical driving condition, a determination is made as to whether the ascertained values exceed an upper limiting value and, subsequently, fall below a lower limiting value, or whether the ascertained values fall below a lower limiting value and, subsequently, exceed an upper limiting value. Furthermore, a determination is also made as to whether the time interval between a first time point associated with the exceeding of the upper limiting value and a second time point associated with the falling below of the lower limiting value does not meet a specifiable time threshold value.

摘要:
A stability monitoring and alarm system for a motor vehicle (e.g., a truck or a tractor trailer) provides an early warning to the driver of unsafe or potentially unsafe conditions. Front wheel desynchronization and rear load distribution are each monitored, and an alarm is generated if either the front wheels become desynchronized or the load is unevenly distributed in the rear of the vehicle. Various filtering and averaging techniques avoid false alarms and increase reliability and sensitivity. Thresholding of the front wheel desynchronization comparison is based on a model which takes turning lateral G force for particular speeds into account so that an alarm based on front wheel descynchronization is not generated because of taking turns too rapidly. Rather, such alarm is generated by monitoring shifting rear load distribution --a better and more accurate measure of vehicle stability. The resulting indications provided by an easy to read user interface warn the driver of a variety of conditions (e.g., loss of traction due to hydroplaning or ice, shifting rear load, equipment failure, etc.) to help avoid accidents.
