The TLX A-Spec SH-AWD has a incomparable 25.4 mm back stabilizer bar that serve enhances turn-in and reduced physique hurl during cornering.

Amplitude Reactive Dampers (ARD)
Acura’s Amplitude Reactive Dampers yield both higher float comfort and sporty handling, assisting a TLX yield a truly enchanting pushing knowledge in all pushing situations. Two apart damping mechanisms are utilized, with one tuned for limit potency on smoother roads with tiny inputs and a other tuned to hoop vast inputs such as serious roads, potholes, and remarkable steering and braking action. Front triple-path check mounts serve urge float comfort though sacrificing handling. The outcome is a automobile that stays stoical and gentle in a far-reaching operation of conditions.

Amplitude Reactive Dampers have dual apart damping pistons. To urge altogether float comfort, when smaller inputs start during normal pushing conditions, usually a categorical piston works to yield a ideal damping characteristics. To urge a TLX’s float and doing during some-more serious conditions, a second piston operates to yield additional damping force.

Amplitude Reactive Dampers work on a quite mechanical/hydraulic basement and do not need electronic controls.

Vehicle Stability Assist™ (VSA®)
The TLX’s Vehicle Stability Assist™ (VSA®) works in and with a Drive-by-Wire stifle complement and ABS to raise automobile fortitude when cornering: If automobile understeer or oversteer is detected, a complement selectively reduces energy and/or relates braking force to particular wheels to assistance scold a condition and stabilise a vehicle.

VSA also supports a operation of accessible driver-assistive technologies such as Adaptive Cruise Control (ACC) with Low-Speed Follow, Collision Mitigation Braking System™ (CMBS) and Road Departure Mitigation (RDM). The advantages of a TLX’s VSA complement embody discerning response with well-spoken activation, rarely accurate control and brake-pedal feel, and low doing noise, quivering and rudeness (NVH).

In addition, VSA monitors circle slippage, such as when starting on pointy surfaces or rags of ice. If slippage is detected, VSA activates one or some-more stop calipers and reduces engine torque to delayed a spinning wheel(s) so traction can be regained. VSA is enclosed on all front-wheel expostulate and SH-AWD models.

Integrated Dynamic System (IDS)
ECON, Normal, Sport and Sport+ modes concede a motorist to customize their pushing experience.

To control a spin of support a Powertrain Control Module receives signals from a speed sensor and, joined with a steering sensor for torque and rotation, afterwards calculates a optimal volume of support and sends a vigilance to a electric motor.

When compared to a operation of a compulsory hydraulic siphon energy steering system, a easier MA-EPS increases potency since it does not lift a continual volume of energy directly from a engine. Other advantages of electric power-assisted steering embody simplicity, and compactness.

Vehicle Stability Assist™ (VSA®) Integration
MA-EPS and Vehicle Stability Assist™ (VSA®) work together as one worldly complement to significantly raise active safety. The fortitude record triggers steering inputs that prompt a motorist to expostulate in a scold instruction when a boundary of traction are approached.

Using automobile speed and steering angle data, MA-EPS works with VSA to detect instability in low traction conditions (both during cornering and underneath braking) and automatically triggers steering inputs directed during call a motorist to expostulate in a scold direction. This modernized record supports a driver’s movement in doing a automobile some-more safely and comfortably.

Below are 3 examples of how MA-EPS works as partial of VSA.

  • Mitigates Understeer — Helps scold steering inputs to lessen understeer and assistance a motorist snippet a bend of a road.
  • Mitigates Oversteer — Helps scold steering inputs to lessen oversteer and assistance a motorist snippet a bend of a road.
  • Stabilizes Braking — Helps scold steering submit to revoke automobile instability when braking tough on highway surfaces with varying attrition coefficients (such as cement that is usually partially lonesome with mud or snow).

Integrated Dynamics System (IDS) Integration
MA-EPS also integrates with a TLX’s customary Integrated Dynamics System (IDS). At a driver’s discretion, a steering response can be switched between dual striking steering settings (Normal: when in Normal or ECON, and Sport: when in Sport or Sport+). (See subsequent for some-more information.)

Precision All-Wheel Steer™ (P-AWS)
Standard on all front-wheel expostulate TLX models, Precision All-Wheel Steer™ (P-AWS) helps a TLX motorist uniformly and simply snippet a preferred line with smaller steering-wheel inputs. The outcome is superb energetic opening during all speeds, providing a TLX motorist with a many enchanting pushing knowledge possible.

In operation, P-AWS invariably monitors and calculates a scold volume of rear-toe angle submit compulsory for a conditions, examining steering input, engine and highway speed, transmission, stifle position, stop pressure, bend rate, parallel acceleration and other factors. The limit volume of rear-wheel toe angle composition is 1.8 degrees in possibly instruction (positive or negative) for a sum operation of 3.6 degrees.

P-AWS automatically and ceaselessly adjusts a toe angle of any back circle to compare pushing situations such as branch during an intersection, pushing on breezy roads, merging or exiting a highway, high-speed maneuvers or snowy conditions. The P-AWS complement provides confidence-building cornering capability by softened responsiveness and automobile control. Examples include:

  • Secure Highway Cruising — When a motorist triggers a lane-change maneuver requiring that a TLX orderly pierce into a subsequent lane, a P-AWS complement adjusts a back circle toe angles in proviso (the same direction) with a front wheels enabling quick, purify and fast maneuvering.
  • City Agility and Easy Parking — For sharp low-speed turns, such as on city streets or in parking lots, a P-AWS complement adjusts a back circle toe angles out of proviso (the conflicting direction) with a front wheels. This formula in a tighter branch radius and reduces motorist effort.
  • Fun to Drive on Winding Roads — When tracing a lines of a twisty highway (or assisting a TLX lane quietly in snowy conditions) a P-AWS complement counteracts understeer by assisting broach bend — a compulsory rotational outcome — by a corner.

P-AWS Modes
P-AWS can yield rear-wheel toe-in, in-phase steering or out-of-phase steering, depending on a energetic mandate as commanded by a complement ECU. Specific pivotal rear-wheel toe angle adjustments include:

Agile Handling Assist (AHA)
