A vehicle equipped with a steer-by-wire system is able to steer some or all of its wheels without a steering column connected to the wheel axles. It is different from electric power steering or power-assist, as those systems still rely on the steering column to mechanically transfer some steering torque to the wheels. [15]
The Infiniti Q50 was the first production road-vehicle without a traditional steering column, though one was still equipped as a backup. [2] Steer-by-wire without the use of a steering column was first offered in a production car with the Infiniti Q50 in 2013. [4] The system has a backup steering column separated from the steering wheel with a ...
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

The other big change for GM, of course, is the October accident involving one of Cruise’s self-driving Chevy Bolts in San Francisco (in which a woman was dragged underneath the car), and the ...
In 2013, direct-drive sim steering wheels were introduced in large scale to the consumer mass market as a more advanced alternative to gear- and belt-driven steering wheels. The first commercially broadly available direct-drive wheel base was released in 2013 by the UK-based Leo Bodnar Electronics , after having been retailing to racing teams ...
Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
If a driver is not wearing a seat belt, the signs will show a message such as “BUCKLE UP.” If a driver is on their phone, the signs will say something such as “PHONE DOWN.” The signs will ...
ESC intervenes only when it detects a probable loss of steering control, such as when the vehicle is not going where the driver is steering. [29] This may happen, for example, when skidding during emergency evasive swerves, understeer or oversteer during poorly judged turns on slippery roads, or hydroplaning .
