First Claim
Patent Images
1. A vehicle monitoring system comprising:
- a service/control pressure line;
an emergency/supply pressure line;
a brake valve coupled to a brake actuator and operating the brake actuator, said brake valve coupled to the service/control pressure line and the emergency/supply pressure line, the service/control pressure line and the emergency/supply pressure line each being configured to provide pressurized air to the brake valve;
a brake monitoring device having a processor and coupled to the service/control pressure line and the emergency/supply pressure line, the monitoring device monitoring the pressure of both the service/control pressure line and the emergency/supply pressure line;
said processor comparing the measured pressure of said service/control pressure line and said emergency/supply pressure line to a pressure set point; and
said brake monitoring device generating a warning indication based on at least one of the following parameters selected from the group consisting of;
the measured pressure exceeds a first threshold level or the measured pressure fails to exceed a second threshold level or combinations thereof.

Abstract
A vehicle monitoring system for monitoring pressures on the service and emergency brakes, tires and suspension of a tractor trailer. The system also monitors electrical stoplight power to the ABS brakes as well as various additional vehicle systems listed within the claims. The monitoring system also provides visual and audible alarms to the operator as well as an additional output to signal a wireless device to warn the operator'"'"'s employer if the warning is ignored.
