A method for monitoring the temperature of a friction brake to prevent overheating of the brake is disclosed. The vehicle speed and brake activation time are monitored for braking event conditions known to add heat to the brake or brakes, and the frequency or rate of occurrence of these conditions is monitored. When the frequency of brake event conditions approaches a threshold value known to be approaching an over-temperature condition, the speed of the vehicle is limited in order to limit the amount of kinetic energy which can be absorbed by the brakes, thereby preventing the brakes from overheating.

A method and/or apparatus for reducing the maximum speed of a lift truck when a fork carriage exceeds a fork carriage trip height and a limit switch positioned at the trip height to detect trip height has failed. Using lift truck control signals, a calculated fork carriage height is determined and compared to the trip height which corresponds to the limit switch position. When the calculated height reaches the trip height and the limit switch does not provide a sensed signal, a latch is set in a non-volatile memory which limits the maximum truck speed until the limit switch is again operable.
