Example Embodiment

[0023] Example one

[0024] The first embodiment of the present invention provides an EPB system. In this embodiment, the driver detection unit 11 is a capacitive sensing unit. The capacitive sensing unit is composed of a capacitance detection unit 111 and an MCU 112. The capacitance detection unit 111 and the MCU 112 Make up the PCB. The capacitive sensing unit in this embodiment is arranged under the driving seat of the car. figure 2 This is a schematic structural diagram of the EPB system provided in the first embodiment of the present invention.

[0025] The capacitance detection unit 111 is used to collect the capacitance value above the driving seat; the MCU 112 is used to determine whether there is a driver on the driving seat according to the capacitance value collected by the capacitance detection unit 111. In addition, the electrical signal triggered by the signal triggering unit 13 may be an analog signal or a digital signal.

[0026] In this embodiment, the main contro...

Example Embodiment

[0030] Example two

[0031] The second embodiment of the present invention provides an EPB system, image 3 This is a structural diagram of an EPB system provided by an embodiment of the present invention. In addition to the units in the first embodiment, the system also includes a pressure sensing unit 20.

[0032] The pressure sensing unit 20 is used to collect the pressure value of the driver's seat and determine whether it is the weight of an adult according to the collected pressure value.

[0033] In this embodiment, the signals output by the pressure sensing unit 20 and the capacitive sensing unit are both input to the main control unit 12. When the MCU 112 of the capacitive sensing unit determines that there is a driver on the driving seat, and the pressure sensing unit 20 After judging the weight of an adult according to the pressure value, if the main control unit 12 judges that the driver in the driving seat is leaving according to changes in the capacitance value and / or ...

Abstract

The invention provides an EPB (electronic parking brake) system, which comprises a driver detection unit, a master control unit, a signal trigger unit, a brake control unit and a brake unit. The driver detection unit is used for detecting whether a driver is seated on a driving seat or not, the master control unit is used for controlling the signal trigger unit to trigger electric signals when the driver detection unit detects that the driver leaves the driving seat, and the brake control unit is used for controlling the brake unit to brake according to the electric signals triggered by the signal trigger unit. Using the EPB system can automatically brake an automobile without any operation when the automobile is parked and the driver leaves, so that the problem that the driver forgets to start the EPB system is avoided.

Description

technical field [0001] The invention relates to the field of automobile electronic control, in particular to an electronic parking brake system. Background technique [0002] Automotive electronic parking brake system, also called Electric Parking Brake (EPB) system, is generally activated by electrical signals. The working principle of the EPB system is the same as that of the traditional hand brake or pedal parking brake. It achieves the purpose of keeping the vehicle stationary through the frictional resistance generated by the brake disc and the brake pad, but the control method has changed from the previous hand-pulled or foot-operated type to the button type. [0003] The EPB system is mainly composed of electronic controllers, motors, reduction gears and other components. To control the opening and closing of the EPB system, the driver only needs to press the button of the EPB electronic handbrake. When the driver presses the button, the electric signal It will be tr...
