A
vehicle brake effect motoring and alarm
system belongs to the technical field of vehicle
electron and safety. The outputs of a
vehicle brake pedal displacement sensor and a
vehicle brake pressure sensor are respectively connected with the input of an information collection and
control unit; the output of the information collection and
control unit is connected with the
signal input of an
alarm device. Due to being corresponding to the
stroke of a
brake pedal, the information collection and
control unit carries out evaluation on the
brake effect risk degree R of the vehicle according to a vehicle
brake pressure
signal BPact that is actually collected by the information collection and control unit as well as a benchmark
brake pressure signal BPline2, and gives an alarm to a driver by transmitting a signal to an
alarm device according to the evaluated risk degree R. The information collection and control unit is Motorola MC9S08DZ60. The vehicle brake effect motoring and alarm
system improves the reliability of the
system, has great help on preventing the traffic accidents caused by the losing and reducing of the brake effect, can adopt grading alarm according to the damaged degree of the brake performance, is simple in
system structure, is easy to be achieved and has low cost.
