Embodiment 1

[0020] The present invention is an electronic parking brake method, such as figure 1 As shown, the vehicle controller in the vehicle is used as the vehicle control mechanism, which can exchange signals with the shifter, transmission lock mechanism and EPB electronic parking mechanism on the vehicle, and at the same time, the vehicle controller can judge whether the seat belt is connected to the main vehicle. The state of the driving door, so as to judge the driver’s parking, and choose to use the parking method. The above technologies are all existing technologies, so I won’t elaborate more; The gear control transmission lock mechanism performs parking and the EPB electronic parking mechanism performs parking.

[0021] If the current gear is in the driving gear or neutral gear and the vehicle is turned off, the transmission locking mechanism and the EPB electronic parking mechanism are controlled to perform parking, such as figure 2 As shown, when the vehicle stops, the IGON...

Embodiment 2

[0023] Such as image 3 As shown, if the current gear is in the P gear, the transmission lock mechanism and the EPB electronic parking mechanism are controlled to perform parking. Since the gear position is in the P position, the driver has the intention to park the car. After the driver stops the car and puts it into the P position, the speed of the vehicle drops below 2km / h, the driver steps on the brake to stop, and the electronic shifter sends a parking request to the car. Vehicle controller, after detecting the vehicle speed signal and braking signal, the vehicle controller sends a parking command to the transmission locking mechanism when the conditions are met. After the transmission locking mechanism is locked, the transmission is locked; at the same time, the transmission is locked. The locking mechanism sends out a locking completion signal, and the EPB electronic parking mechanism brakes the wheels after receiving this signal.

Embodiment 3

[0025] Such as figure 2 As shown, if the current gear is not in the P position, IGON (ignition switch) is turned off, and the vehicle speed drops below 2km / h, then judge the status of the door and seat belt, and decide whether to put the gear on according to the status of the door and seat belt. Put into P file and perform parking.

[0026] Judging the status of the doors and seat belts includes:

[0027] If the driver's seat belt is fastened, it is determined that the driver has no parking behavior;

[0028] If the seat belt of the driver's seat is not in the fastened state, it is further judged whether the state of the door is switched from the closed state to the open state;

[0029] If the state of the door is switched from the closed state to the open state, it is determined that the driver has a parking behavior, then the EPB electronic parking mechanism and the transmission lock mechanism are controlled to perform parking, and the vehicle controller switches the gear...

Abstract

The invention belongs to the field of automobile control, and relates to an electronic parking braking method. After a vehicle is parked, the gear of a vehicle gear shifter is judged, and a transmission locking mechanism and an EPB electronic parking mechanism are controlled to execute parking according to different gears. According to the method, the transmission locking mechanism and the EPB are controlled to intervene according to the current gear state of the vehicle, so that the vehicle can be parked when a driver forgets to pull up the parking brake, and the safety of the vehicle and the personal safety are guaranteed; and the parking brake is safer and more reliable, and the operation is more convenient and intelligent.

Description

technical field [0001] The invention belongs to the field of automobile control and relates to an electronic parking brake method. Background technique [0002] At present, whether it is a mechanical parking brake or an electronic parking brake, basically you need to manually pull up the handle or touch the button. If you forget to pull up the parking brake when getting off the car, the car will often slip And so on, very dangerous. Contents of the invention [0003] In order to solve the above problems, the present invention provides an electronic parking brake method, which can timely control the transmission lock mechanism and the EPB electronic parking mechanism according to the current user's driving behavior, so that the parking brake is safer and more reliable and the operation is more convenient ,intelligent. [0004] The present invention relates to an electronic parking braking method. When the vehicle is parked, the gear position of the vehicle shifter is judg...
