Dynamic steering response

Dynamic steering response (DSR) is a car safety technique that corrects the rate of hydraulic or electric power steering system to adapt it to vehicle's speed and road conditions. Similar to DIRAVI, this system was first featured in the SEAT Leon Cupra R and has since been used in a wide range of models including the Ibiza, Cordoba, new Leon, Altea and new Toledo.

Working

It works through a precisely controlled electric motor, which is mounted on top a hydraulic steering gear. For the motor's control, it picks up the data at 2000 times a second (as in Volvo truck FM Series) based on the input from the driver, and from the on-board sensors. Its purpose is to provide precise steering control in every situation.

Benefits

It increases the vehicle's maneuverability, making it more comfortable to drive. This takes away the physical effort of steering even at low speeds, regardless of how heavy the load is, by continuous feedback and sensing by the system. It improves the directional stability at high speeds, so that no small steering adjustments are needed. It diminishes the effect of road disturbances such as bumps and potholes, on the steering wheel at the cockpit. It detects the unwanted deviations in the wheels, with the electric servo motor balances it out.

gollark: It's a short program.
gollark: Command? This is a really inefficient way to obfuscate just a single Li-NUX command.
gollark: Anyway, that command is very safe and Lin-UX users should run it.
gollark: This module contains functions that can read and write Python values in a binary format. The format is specific to Python, but independent of machine architecture issues (e.g., you can write a Python value to a file on a PC, transport the file to a Sun, and read it back there). Details of the format are undocumented on purpose; it may change between Python versions (although it rarely does). [1]This is not a general “persistence” module. For general persistence and transfer of Python objects through RPC calls, see the modules pickle and shelve. The marshal module exists mainly to support reading and writing the “pseudo-compiled” code for Python modules of .pyc files. Therefore, the Python maintainers reserve the right to modify the marshal format in backward incompatible ways should the need arise. If you’re serializing and de-serializing Python objects, use the pickle module instead – the...
