  • Method and apparatus for determining vehicle brake effectiveness
    Patent number: 6332354
    Abstract: This invention relates to a method and apparatus for determining the effectiveness of a vehicle braking system and for measuring changes in the mass of a wheeled vehicle. The method and apparatus include manually or automatically measuring and inputting vehicle mass to a computer, measuring and inputting brake system pressure during deceleration of the vehicle in a normal operating mode, measuring and inputting road slope, measuring and inputting air friction and engine friction of the vehicle, determining a predicted deceleration of the vehicle, measuring actual deceleration of the vehicle, and providing and using a computer to calculate the effectiveness of the vehicle braking system from data representing actual deceleration of the vehicle, road slope, air friction, engine friction, brake system pressure, vehicle mass, and predicted deceleration for the vehicle under comparable circumstances, and generating a signal representative of the effectiveness of the vehicle braking system.
