The utility model discloses a solve above-mentioned technical problem through following technical scheme:

the utility model provides an automobile electronic parking system with emergency release function, which comprises an EPB switch button, an EPB electronic control unit, a caliper actuator, a relay, an EPB emergency release switch and a battery; the EPB switch button is electrically connected with the EPB electronic control unit, and the EPB electronic control unit is electrically connected with the caliper actuator through a relay to form an EPB normal function circuit; the battery, the EPB emergency release switch and the relay are electrically connected in sequence, and the relay is electrically connected with the caliper actuator to form an EPB emergency release line.

The electronic parking system of the automobile further comprises a terminal, and the terminal, the EPB electronic control unit and the caliper actuator are sequentially and electrically connected to form an EPB emergency release line.

Preferably, the relay is a high current relay.

Preferably, the EPB emergency release switch is mounted on a vehicle instrument panel.

On the basis of the common knowledge in the field, the above preferred conditions can be combined at will to obtain the preferred embodiments of the present invention.

The utility model discloses an actively advance the effect and lie in:

the utility model discloses an emergency release function can realize the braking release under the condition that the car breaks down, provides very big facility for the trailer maintenance. And (3) giving an emergency release instruction to the EPB electronic control unit card-issuing clamp by using a mobile phone, and releasing the clamp to enable the vehicle to normally run. Also can exert reverse operating voltage through vehicle EPB emergency release switch, through heavy current relay for the calliper motor, let calliper compelled release, reach the vehicle and can continue to travel the purpose.

Drawings

Fig. 1 is a schematic diagram of an electronic parking system with an emergency release function for an automobile according to a preferred embodiment of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, the present embodiment provides an electronic parking system for an automobile with an emergency release function, which includes an EPB switch button 1, an EPB electronic control unit 2, a caliper operator 3, a large current relay 4, an EPB emergency release switch 5, and a battery 6, the EPB emergency release switch 5 may be mounted on an instrument panel of the vehicle.

The EPB switch button 1 is electrically connected with an EPB electronic control unit 2, and the EPB electronic control unit 2 is electrically connected with a caliper actuator 3 through a large-current relay 4 to form an EPB normal function circuit.

The battery 6, the EPB emergency release switch 5 and the high-current relay 4 are electrically connected in sequence, and the high-current relay 4 is electrically connected with the caliper actuator 3 to form an EPB emergency release circuit.

The automobile electronic parking system further comprises a terminal, and the terminal, the EPB electronic control unit 2 and the caliper operator 3 are sequentially and electrically connected to form an EPB emergency release line.

And under the normal working condition of the automobile, the EPB normal function circuit works. When the brake is parked, a driver pulls the EPB switch button 1, the EPB switch button 1 sends a parking signal, and after the EPB electronic control unit 2 receives the parking signal, the positive working current is applied to a caliper motor of the caliper actuator 3 through the large-current relay 4, so that the clamping brake is realized. When releasing, the driver pulls down EPB shift knob 1, and EPB shift knob 1 sends the release signal, and EPB electronic control unit 2 receives the release signal after, applys reverse operating current for the calliper motor of calliper effect ware 3 through heavy current relay 4, realizes releasing.

Under the condition that the automobile breaks down, for example, a detection system or a connecting line has a problem, the EPB diagnoses that the automobile breaks down, namely enters a safety protection state, and the clamping of the calipers cannot be released. At the moment, the driver touches the EPB emergency release switch 5, and the high-current relay 4 disconnects the normal function circuit and connects the emergency release circuit after receiving the signal, so that the release is realized.

This embodiment can be when vehicle calliper is urgent to be pressed from both sides tightly, installs an EPB emergency release switch additional at vehicle instrument panel, can control when calliper system presss from both sides tight unable automatic release, launches this simple key release function, solves the urgent problem that can not move of breaking down of vehicle, improves vehicle EPB performance, vehicle travelling comfort. And an emergency release instruction can be sent to the EPB electronic control unit 2 by a mobile phone with the Bluetooth function, so that the EPB electronic control unit 2 can emergently shield all fault information release calipers, and the purpose that the vehicle can be moved is achieved.

The utility model relates to an automotive electronics parking system with emergency release function, EPB emergency release circuit can realize the braking release under the condition that the car breaks down to the trailer maintenance of being convenient for.

Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
