Parking braking control device

The utility model provides a parking braking control device, which belongs to the technical field of automobiles, and solves the problem that the existing parking braking system cannot judge whether the automatic parking braking function is executed or not intelligently. The parking braking control device comprises a controller, a wheel speed sensor and an induction executive circuit, wherein the wheel speed sensor and the induction executive circuit are connected with the controller respectively; the controller is also connected with a vehicular bus; the induction executive circuit comprises a power supply 1, a switch 1, an execution unit and a seat switch, which are connected in series in sequence to form a circuit, wherein the switch 1 is connected with the controller, the execution unit is used to control a manual brake and the seat switch is used to detect whether a driver on a driver's seat leaves from the driver's seat and open or close the circuit; and when the driver leaves from the driver's seat without tightening the manual brake and the controller receives the information that the wheel speed sensor detects that the rotating speed of the wheel exceeds the set value, the seat switch is closed, the controller controls the switch to be closed to conduct the circuit, and the execution unit is powered by the power supply to tighten the manual braking. The parking braking control device has the function of judging and executing the automatic parking braking intelligently.
