Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the car's throttle to maintain a steady speed set by the driver.
The large hand-levers set the rear-wheel parking brake and put the transmission in neutral (left) and control an after-market 2-speed transmission adapter (right). Car controls are the components in automobiles and other powered road vehicles, such as trucks and buses, used for driving and parking.
The radar-assisted system maintained continuous control from speeds from 0 to 100 km/h (0 to 62 mph) and is designed to work under stop/go situations such as highway traffic congestion. [27] 2007: BMW introduced full-speed Active Cruise Control Stop-and-Go on the BMW 5 Series (E60). [28] 2008: Lincoln introduced radar ACC on the 2009 Lincoln MKS.
These cams would actuate switches to turn on the lights in sequence. Later Ford cars and the 1969 Imperial used a transistorised control module with no moving parts to wear, break, or go out of adjustment. FMVSS 108 has been officially interpreted as requiring all light sources in an active turn signal to illuminate simultaneously.
Red light running occurs when a motorist enters a junction any time after the signal light turns red unless a legal turn on red manoeuvre is completed. [3] A US national survey in 2019 found that 86% of drivers thought it was very dangerous to run a red light at speed, but 31% reported that they had done so in the past 30 days. [4]
Lights are timed in such a way that motorists can drive through without stopping if their speed is lower than a given limit, mostly 50 km/h (30 mph) in urban areas. This system is known as "grüne Welle" in German, "vague verte" in French, or "groene golf" in Dutch (English: "green wave"). Such systems were commonly used in urban areas of the ...
When the car goes into the limp-home-mode it is because the accelerator, engine control computer and the throttle are not connecting to each other in which they can function together. The engine control computer shuts down the signal to the throttle position motor and a set of springs in the throttle set it to a fast idle, fast enough to get ...
Speed appropriate to the hazard being approached, attained via explicit braking or throttle control (engine braking), always being able to stop in the distance you can see to be clear on your side of the road; Gear appropriate for maximum vehicle control through the hazard, selected in one shift; and; Acceleration for clearing the hazard safely.
