1. A limiting system warning when a golf car is improperly driven comprising:

  • a housing;

    sensor probe means, located on said housing, mounted under said golf car for producing contact signals dependent upon the frequency and vertical impact of a contact point along the horizontal movement therealong;

    first amplifier filter means, located in said housing, for producing selected electrical frequency signals in response to said contact signals for reducing improper signal pickup from said sensor probe;

    signal detecting means, located in said housing, responsive to said selected electrical frequency signals producing a first electrical signal when said golf car is stationary, producing a second electrical signal when said golf car is traveling on the grass, and a third electrical signal when said golf car is traveling on the car path;

    time constant means, located in said housing, for producing a delayed first electrical signal and a delayed second electrical signal, producing said delayed first electrical signal responsive to said first and said second electrical signal, producing said delayed second electrical signal responsive to said third electrical signal;

    delayed control means, located in said housing, for producing a delayed third electrical signal responsive to either said second or said third electrical signal indicating when said golf car beings traveling, said delayed control means being further adapted for indicating when said golf car is stationary by producing a delayed fourth electrical signal responsive to said first electrical signal;

    memory means, located in said housing, for producing a fourth and fifth electrical signal responsive to said delayed first and said delayed second electrical signal respectively for memory of the last surface said golf car has traveled on;

    clamp means, clamping said delayed first and said delayed second electrical signals to a level which does not allow said memory means to respond to a level change until said delayed control means produces said delayed third electrical signal;

    timing means, located in said housing, for counting a first predetermined time period and a second predetermined time period after counting said first predetermined time period, said <

    the>

    timing means further being adapted for counting a third predetermined time period after said second predetermined time period has expired;

    alarm means for sounding an alarm when said fourth electrical signal occurs and said first predetermined time period is counted by said timing means, said alarm means being further adapted for a silencing of said alarm when said fifth <

    sixth>

    electrical signal occurs;

    deactivating means for ending operation of said golf car after said second predetermined time period is counted by said timing means;

    switching means for manually resetting said deactivating means and silencing said alarm, allowing use of said golf car with assistance of said limiting system, said switching means also for manually bypassing said limiting system allowing use of said golf car without assistance of said limiting system.
