Patent Images
1. A method for determining a brake overheating condition, comprising:
- sensing a travel speed of a vehicle having a brake, and responsively producing a speed signal;
sensing an application state of the brake and responsively producing an brake application signal;
sensing an application time of the brake and responsively producing a time signal; and
receiving at least two of the speed, brake application, and time signals and responsively producing a brake overheat signal.

Abstract
A vehicle includes at least one wheel and an associated brake. Especially if the vehicle is traveling down an incline, the brake may overheat from prolonged use. The present invention provides an operator warning device which alerts the operator to a possible or actual brake overheat condition, based on any number of chosen non-temperature vehicle conditions. These conditions may include incline, machine speed, brake application pressure, and brake application duration.

8. A method for determining an overheating condition of a brake on a vehicle, comprising:
-
generating a brake overheat signal based on at least two of;
a duration of application of the brake, a pressure of application of the brake, a travel speed of the vehicle, and an inclined state of the vehicle; and
activating a warning device responsive to the brake overheat signal being outside a predetermined acceptable overheat signal range.

9. A vehicle, comprising:
-
a machine body;
an operator compartment associated with the vehicle; and
a ground engaging system providing motive power to the machine body, including at least one wheel, at least one brake associated with the wheel, and a brake overheat warning system associated with the brake, the brake overheat warning system including;
an electronic control module;
a machine speed sensor adapted to produce a machine speed signal;
a brake application sensor adapted to produce a brake application duration signal; and
wherein the electronic control module receives the machine speed and brake application duration signals and responsively produces a brake overheat signal. - View Dependent Claims (10, 11, 12, 13)
