Abstract:
An advance warning device for monitoring the working conditions of a hydraulic braking system of a motor vehicle, said advance warning device comprising:a brake lining temperature sensor for monitoring the temperature of a brake lining piece of the hydraulic braking system of the motor vehicle;a distribution pump temperature sensor for monitoring the temperature of hydraulic brake fluid contained in a distribution pump of the hydraulic braking system of the motor vehicle;a water content sensor for monitoring water content of the hydraulic brake fluid of the hydraulic braking system of the motor vehicle;a hydraulic pressure sensor for monitoring the hydraulic pressure of hydraulic brake fluid of the hydraulic braking system of the motor vehicle, said hydraulic pressure sensor including a sensing end which is located in proximity to a fluid inlet of a distribution pump of the hydraulic system of the motor vehicle such that said sensing end of said hydraulic pressure sensor is in contact with hydraulic brake fluid; anda controller for receiving signals transmitted by said sensors, said signals being compared by said controller with advance warning data stored in a memory which is located inside or outside said controller,wherein said advance warning data includes advance warning hydraulic pressure signal data, and p1 wherein said controller includes an input end and an output end, said input end being connected with a signal output end of said hydraulic pressure sensor for receiving a hydraulic pressure signal of the hydraulic brake fluid transmitted by said hydraulic pressure sensor such that said hydraulic pressure signal is compared by said controller with said advance warning hydraulic pressure signal data.
