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.
Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself. [3] For example, the driver is able to set the cruise control to 55mph, if the car while traveling that speed catches up to another vehicle going only 45mph, the ACC will cause the car to automatically brake and maintain a safe distance behind the ...
The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches.
When in Engine Control Room mode the bridge handle sends a telegraph signal to the ECR and the ECR handle controls the set point of the control system. In local control, the remote control system is inactive and the bridge handle sends a telegraph signal to the local control position and the engine is operated by its manual controls in the ...
Specific cruise control systems can accelerate or decelerate, but require the driver to click a button and notify the car of the goal speed. [36] ESC control light; Electronic stability control (ESC) can reduce the speed of the car and activate individual brakes to prevent understeer and oversteer. [37]
This is the speed at which drag is minimised. For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
Feldman said cruise ships typically leave the gangway open all night for guests. "You can come and go as you please," he said. "And if you want to go out and, let's say, party until 3 in the ...
The speed difference to allow an automatic stop was raised to 50 km/h (31 mph) in 2013 with improved cameras. [49] The adaptive cruise control was also upgraded in 2010 to allow automatic emergency braking in traffic, fully stopping the EyeSight vehicle when the car in front has come to a complete stop. [47]
