Traffic signal timing is a very complex topic. For example timing a 'WALK' signal for a wide pedestrian crossing and slower pedestrians (for example the elderly) could result in very long waits for vehicles, and thus increases the likelihood of cars running the light, which could potentially cause accidents. Therefore, optimizing the safety of ...
Image detection devices exhibit numerous problems including degradation during bad weather and lighting. Traffic actuated signal systems use detectors to adjust timing for: Only the main street - semi-actuated system; Both main and cross streets - fully actuated system. The above method is primitive real-time signal optimization at best.
A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
These delayed signals cause measurement errors that are different for each type of GPS signal due to its dependency on the wavelength. [4] A variety of techniques, most notably narrow correlator spacing, have been developed to mitigate multipath errors. For long delay multipath, the receiver itself can recognize the wayward signal and discard it.
This sensor is one of the two most important sensors in modern-day engines, together with the camshaft position sensor. As the fuel injection (diesel engines) or spark ignition (petrol engines) is usually timed from the crank sensor position signal, failing sensor will cause an engine not to start or will cut out while running.
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
European car manufacturers started using different serial communication technologies, which led to compatibility problems. In the late 1990s, the LIN Consortium was founded by five automakers ( BMW , Volkswagen Group , Audi , Volvo Cars , Mercedes-Benz ), with the technologies supplied (networking and hardware expertise) from Volcano Automotive ...
Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne. [1] It is a stepless, fully- automatic transmission , consisting of a V-shaped drive-belt, and two pulleys , each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle ...
