Vehicle Communications and Navigation

Guiding drivers down the right road

High-speed data and voice communication is essential to the success of intelligent transportation systems. HP diodes, transistors and ICs are used in GPS navigation systems as well as cellular and PCS handsets--important links in the transportation industry of today and tomorrow.

HP has also pioneered the development of low-cost, integrated infrared transceivers and discrete emitters and detectors that provide low-cost short-distance links between computers, peripherals and equipment controllers in the office. This same proven technology offers simple and reliable cableless data links for the transportation industry.

RF technology in motor vehicles

Radio frequency links can meet a number of requirements for near-term developments in the motor vehicle. For example, an RF transmitter in the car can provide a link to a remote diagnostic computer, aiding the fleet operator in monitoring vehicle performance, without having to even open the hood or plug in a cable.

HP RF components are used to provide vehicle identification information for automated toll collection. High-performance microwave components offer one possible way of providing low-cost capabilities for assisted braking or autonomous collision avoidance capabilities. RF technology is used to send coded signals from a keychain transmitter to provide reliable keyless entry from a distance, without removing the transmitter from purse or pocket.

HP RF transistors, integrated circuits and diodes are an integral part of mobile communications as well as global positioning system (GPS) satellite receivers. GPS receivers, coupled with navigation displays, have been available in some passenger cars since about 1994. Applications are also being developed in which GPS is used to manage commercial truck and van delivery fleets, giving dispatchers constant data on vehicle positions and allowing vehicles to be re-routed in real time to minimize fuel costs and emissions into the atmosphere.

Infrared technology in motor vehicles

HP infrared emitters, detectors and transceivers can also meet a number of requirements for near-term developments in the motor vehicle. For example, an IR transceiver in the car can provide a link to a hand-held diagnostic computer, aiding the technician in quickly finding vehicle problems, again without having to even open the hood or plug in a cable.

Limited-distance IR transmission can be used to provide vehicle identification information for automated toll-taking. High-performance infrared functionality offers one possible way of providing low-cost “light-radar” capabilities for assisted braking or autonomous collision avoidance capabilities. Infrared technology can also provide safety features such as rain detection to change the braking characteristics of a vehicle or to automatically activate the windshield wipers. Or, it can be used to send coded signals from a keychain transmitter to provide secure keyless entry at short distances.
