Magneto-Optic Tachometers for Automotive Vehicles' Chassis 2002-01-2227

Anti-lock braking systems (ABS) are an accident evasion system (AES) that by incorporating relevant sensory systems (SS), for instance, such as magneto-optic (M-O) tachometers, accelerometers etc., can avoid wheel locking during hard braking in an emergency, especially when the road surface is slippery. Automotive vehicles (AV) lose steering when the front wheels (FW) lock. An ABS uses sensors at each wheel to monitor deceleration when the fluidomechanic (F-M) or electromechanic (E-M) drum, ring or disc brakes are applied. If any of the wheels begin to lock, the ABS will modulate the brake pressure or voltage, thus ‘pumping’ the fluidomechanic (F-M) or electromechanic (E-M) drum, ring or disc brakes, respectively, at the rate faster than the average human driver (HD) could. This will allow the wheel to continue rotating so avoiding locking, and the wheel will remain to react to the steering wheel (SW).
