Threshold braking or limit braking is a driving technique most commonly used in motor racing, but also practiced in road vehicles to slow a vehicle at the maximum rate using the brakes. [1] The technique involves the driver controlling the brake pedal (or lever) pressure to maximize the braking force developed by the tires .
ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage.
Threshold braking maintains a steady braking force with slight (10-20%) slip, around or just below the point of maximum tire grip force. Cadence braking accepts that holding the threshold braking limit is exceptionally hard, and relies on manual manipulation of braking force to rapidly go just above and below the skid point, essentially ...
While cadence braking is effective on most surfaces, it is less effective at slowing the vehicle than keeping the tires continually at the optimum braking point which is called threshold braking. The latter is an expert driving technique that is even more difficult to learn than cadence braking, and again has been largely superseded by ABS ...
2003: Honda introduced autonomous braking (Collision Mitigation Brake System CMBS, originally CMS) front collision avoidance system on the Inspire [29] and later in Acura, using a radar-based system to monitor the situation ahead and provide brake assistance if the driver reacts with insufficient force on the brake pedal after a warning in the ...
Performance Driving is categorized as a driver of an automobile utilizing specific techniques [1] to maximize the performance potential (See also vehicle dynamics) of the automobile during acceleration, turning, and braking maneuvers, typically while driving at a facility dedicated——and specifically constructed——to host automobile motorsport competitive events.
Rowing is the technique of downshifting more than one gear along with the heel-and-toe technique to provide engine braking and smoother deceleration/braking while in the intermediate gears. This provides for maximum braking when going from a top gear to a much lower gear, and optimal engine rpm for exiting the corner. [citation needed]
The difficulty is that the acceleration at the limit of adhesion depends on the road surface, so with the same ratio of front to back braking force, a car will understeer under braking on slick surfaces and oversteer under hard braking on solid surfaces. Most modern cars combat this by varying the distribution of braking in some way.
