    摘要： The present invention relates to a vehicle brake system, which has a brake reservoir, and utilizes a tire management system that is in communication with the brake reservoir and a vehicle operator. As a result of this configuration, the tire management system communicates brake reservoir pressure signals to the vehicle operator, so that the operator is made aware of any low pressure conditions, in the trailer, before trying to move the trailer.

    摘要： A novel diagnostic system for a trailer is provided by the present invention. The trailer includes a micro controller which is part of an anti-lock brake system of the trailer. A warning light is provided on the trailer and is in electrical connection with the micro controller. A switch is provided proximate to the warning lamp. The switch can be activated by a technician to provide a short across the warning lamp. A stored program within the micro controller recognizes the short and performs a diagnostic function in response thereto by flashing the warning lamp in a predetermined manner.

    摘要： A control system includes a microcontroller which receives input signals from input sensors and transmits output signals to electrically actuated solenoid valves in response to the input signals. A drive circuit controller is responsive to the output signals and to a solenoid enable signal generated by a watchdog circuit to control the solenoid valves. The watchdog circuit is responsive to watchdog pulses generated by the microcontroller and transmitted through the watchdog port of the microcontroller to generate the solenoid enable signal. The watchdog circuit generates the solenoid enable signal only when the frequency of the pulses generated at the watchdog port is within a relatively narrow frequency range. Accordingly, the watchdog circuit disables the drive circuits during failure of the microcontroller to assure that the solenoids will not be operated.

    摘要： The present invention provides a circuit which is configured to apply variable hysteresis to an input signal, where the level of hysteresis applied to the input signal is dependent upon the frequency of the input signal. Use of this circuit in a vehicle's anti-lock braking system allows for more efficient and effective braking.

    摘要： A motor vehicle brake control system having traction control and incorporating controller features and methods of operation which interrupt activation of the traction control system in conditions likely to develop excessive brake temperatures, exceed available brake pressure limitations, or other adverse brake conditions. This feature is provided by monitoring the behavior of the system, and based on known braking system characteristics, disabling the traction control when certain parameters are exceeded. The system provides these features without the need to directly measure brake temperature, brake system pressure or other physical parameters.
