Embodiment 1

[0040] Embodiment 1 provided by the present invention is an embodiment of an electronic parking control for automobiles provided by the present invention, combining figure 1 It can be seen that the electronic parking control method includes:

[0041] Step 1. The P button of the shifter is connected to the EPB controller through a hard wire. After receiving the signal that the driver presses the P button, the shifter controls the EPB through the CAN network, PDCM controller and / or hard wire. The device sends the request of EPB request;

[0042] Step 2: After receiving the EPB request, the EPB controller sends an apply or release command according to the current state of the parking caliper, and the parking caliper performs a clamping action or a release action according to the apply or release command to realize parking or parking release of the vehicle .

[0043] In a possible embodiment, step 2 further includes: after the EPB control receives the EPB request, it judges whet...

Embodiment 2

[0061] Embodiment 2 provided by the present invention is an embodiment of an electronic parking control system for a vehicle provided by the present invention, which embodiment includes: a shifter, an EPB controller and a parking brake actuator controller;

[0062] The P gear button of the shifter is connected to the EPB controller through a hard wire;

[0063] After receiving the signal that the driver presses the P key, the shifter sends an EPB request request to the EPB controller through the CAN network, PDCM controller and / or hard wire;

[0064] After receiving the EPB request, the EPB controller sends an apply or release command to the parking brake actuator controller according to the current state of the parking caliper, and the parking brake actuator controller controls the parking caliper to execute according to the apply or release command. Clamping action or release action to realize vehicle parking or parking release.

[0065] It can be understood that the electr...

Abstract

The invention relates to an electronic parking control method and system for an automobile, the electronic parking control method for the automobile comprises the steps that a P-gear key of a gear shifter is connected with an EPB controller through a hard wire, and after the gear shifter receives a signal that a driver presses down the P key, an EPB request is sent to the EPB controller through a CAN network, a PDCM controller and / or the hard wire; after the EPB controller receives the EPB request, an application or release instruction is sent out according to the current state of the parking calipers, the parking calipers execute the clamping action or release action according to the application or release instruction, and parking or parking release of the vehicle is achieved; one more choice can be provided during release, and when the PDCM controller or the CAN network fails, the PDCM cannot send an EPPBquery request to the EPB controller, the parking cannot be released, and the vehicle cannot move, a driver only needs to press a P key, and information can be transmitted to the EPB controller through a hard wire.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an electronic parking control method and system for automobiles. Background technique [0002] Such as figure 1 Shown is a schematic structural diagram of the integrated electronic parking system, composed of figure 1 It can be seen that the existing electronic parking system is composed of EPB (Electric Parking Brake, Electronic Parking Brake System) switch (Parking Brake Switch), EPB controller and wheel brake; the wheel brake includes a parking brake actuator (PBC, Parking Brake) BrakeActuator), which has a left brake caliper and a right brake caliper. The EPB controller runs the software PBC that controls the parking brake actuator, which is used to control the driver's use function, and the necessary accessories (diagnosis, communication, vehicle sensor, operating system, etc.) HOST. [0003] Such as figure 2 Shown is the signal on-off schematic diagram of each g...
