Abstract
A novel spin control system for an engine-driven wheeled vehicle for reducing the power applied to driven wheels of the vehicle when an incipient wheel spin is detected. A normally closed electrically-actuated intake manifold valve is mounted on the intake manifold of the engine for actuation to an open position by an electronic circuit which detects an incipient wheel spin via wheel speed sensors. With the intake manifold vented to atmosphere via the open intake manifold valve, engine intake manifold vacuum drops automatically throttling down the engine irrespective of the carburetor throttle position to reduce the power input to the spinning wheel or wheels thereby effectively counteracting the incipient spin condition.
Claims17
A spin control system for a multi-wheeled vehicle having one of the wheels thereof driven from a fuel-consuming engine having throttle valve means for supplying a fuel/air mixture and an intake manifold for communicating said fuel/air mixture to said engine in which a vacuum is produced when power is supplied by said engine to said one wheel for driving said one wheel, said system comprising:
- sensing means for sensing an incipient wheel spin at said one wheel and for generating a spin signal comprising a series of pulses indicative of the magnitude of said incipient spin;
- and
- valve means in addition to said throttle valve means communicating with said intake manifold and receiving said spin signal, said valve means being capable of venting the intake manifold of said engine in response to said spin signal to sufficiently lower the intake manifold vacuum to thereby sufficiently reduce the power supplied by said engine to said one wheel to counteract an incipient spin, said valve means reducing said engine intake manifold vacuum in accordance with said series of pulses so that the power supplied by said engine is reduced in accordance with the magnitude of said incipient spin.
A spin control system for a multi-wheeled vehicle having an internal combustion engine driving at least one of the wheels thereof, said internal combustion engine having throttle valve means for supplying a fuel/air mixture and an intake manifold for communicating said fuel/air mixture to said engine in which a vacuum is existent when power is supplied by said engine to said one wheel for driving said one wheel, said spin control system comprising:
- sensing means for sensing an incipient wheel spin at said at least one wheel and for generating a spin signal comprising a periodic waveform indicative of the magnitude of said incipient spin;
- normally closed valving means in addition to said throttle valve means communicating the intake manifold of the engine to atmosphere, said valve means being capable of venting the intake manifold of said engine in response to said spin signal to sufficiently lower the intake manifold vacuum to thereby sufficiently reduce the power supplied by said engine to said one wheel to counteract an incipient spin;
- and
- means associated with said valving means for reducing the power supplied by said engine to said one wheel in response to an incipient spin by opening said valving means to a degree in accordance with said periodic waveform to vent the intake manifold to atmosphere in response to said spin signal and to reduce the power supplied in said engine in accordance with the magnitude of said incipient spin.
A spin control system for a multi-wheeled vehicle having an internal combustion engine driving at least one of the wheels thereof, said internal combustion engine having a carburetor for supplying a fuel/air mixture and an intake manifold for communicating the fuel/air mixture to said engine having a mounting flange for said carburetor and in which a vacuum is produced when power is supplied by said engine to said one wheel for driving said one wheel, said spin control system comprising:
- sensing means for sensing an incipient wheel spin at said at least one wheel and for generating a spin signal indicative of said incipient spin;
- normally closed valving means and an adapter means for said valving means which is mounted between the carburetor mounting flange of the intake manifold and the carburetor for communicating the intake manifold of the engine to atmosphere through said valving means;
- and
- means for reducing the power supplied by said engine to said one wheel in response to an incipient spin by opening said valving means in response to said spin signal to thereby vent the intake manifold to atmosphere in response to said spin signal.
