Problems solved by technology

[0003] However, in some scenarios, the driver does not want the AVH function to be activated, such as moving the car, parking scenarios, and in some scenarios, the driver wants to activate the AVH, but does not like to exit the AVH function by stepping on the accelerator, such as in traffic jams. The driver wants to activate AVH to free his feet, but when the vehicle is started, he needs to step on the accelerator to make the AVH function off, which will cause the vehicle to go too fast and easily cause rear-end collision accidents.
[0004] The existing AVH function activation and exit conditions do not take into account the driver's use intention in different scenarios, often causing misjudgment or inconvenience when using it, and easily causing drivers to complain about the AVH function

Embodiment 1

[0030] The activation conditions and exit conditions of the existing AVH function do not consider the driver's use intention in different scenarios, which may easily cause the driver to complain when using the AVH function. In this embodiment, by introducing CAN network signals such as vehicle speed and gear position conditions, on the basis of the original AVH function strategy, the judgment of the driver's intention to use is added.

[0031] The existing AVH function strategy is divided into AVH with switch, which is hereinafter referred to as scheme A, and AVH without switch, which is hereinafter referred to as scheme B.

[0032] For the situation where the driver does not want to use the AVH function, Plan A believes that the driver can manually operate the AVH switch to turn off the AVH function. This method does not identify the driver’s intention to use the AVH function from the algorithm. , the driver has already complained about the activation and deactivation of the ...

Embodiment 2

[0076] Figure 4 It is a schematic structural diagram of an automatic parking hold state control device provided in Embodiment 2 of the present invention. This device is applicable to the situation that the vehicle activates the automatic parking hold function, wherein the device can be implemented by software and / or hardware, and generally integrated in electronic equipment.

[0077] Such as Figure 4 As shown, the device includes:

[0078] An acquisition module 410, configured to acquire the CAN network signal of the vehicle, and determine the current state of the automatic parking maintenance AVH;

[0079] A determining module 420, configured to determine the state transition condition currently satisfied by the AVH according to the current state and the CAN network signal;

[0080] The regulating module 430 is configured to regulate the current state of the AVH according to the state transition condition.

[0081] In this embodiment, the device first obtains the CAN ne...

Embodiment 3

[0091] Figure 5 It is a schematic structural diagram of an electronic device provided by Embodiment 3 of the present invention. Such as Figure 5 As shown, the electronic device provided by Embodiment 3 of the present invention includes: one or more processors 51 and a storage device 52; the processor 51 in the electronic device may be one or more, Figure 5 Take a processor 51 as an example; the storage device 52 is used to store one or more programs; the one or more programs are executed by the one or more processors 51, so that the one or more processors 51 Realize the state control method for automatic parking maintenance as described in any one of the embodiments of the present invention.

[0092] The electronic device may further include: an input device 53 and an output device 54 .

[0093] The processor 51, the storage device 52, the input device 53 and the output device 54 in the electronic equipment can be connected by bus or other methods, Figure 5 Take connec...

Abstract

The invention discloses an automatic parking keeping state control method, device, and equipment and a storage medium. The method comprises the following steps: acquiring a controller area network (CAN) network signal of a vehicle, and determining the current state of an automatic parking brake (AVH); determining a state conversion condition currently satisfied by the AVH according to the currentstate and the CAN network signal; and regulating and controlling the current state of the AVH according to the state conversion condition. According to the method, the judgment of the use intention ofthe driver can be increased through the CAN network signal, the complaint point of the driver for the use of the current AVH function is effectively solved, and the satisfaction degree of the driverfor the AVH function is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automation, and in particular to a state control method, device, device and storage medium for automatic parking maintenance. Background technique [0002] Automatic Vehicle Hold (AVH) is a sub-function of Electronic Stability Control (ESC). When the vehicle is stationary, the AVH function will reserve a certain amount of brake hydraulic pressure so that the driver can release the pedal. At the same time, keep the vehicle still, free the driver's feet, and relieve driving fatigue. When the driver wants to start, he only needs to step on the accelerator pedal, and the AVH will automatically exit. [0003] However, in some scenarios, the driver does not want the AVH function to be activated, such as moving the car, parking scenarios, and in some scenarios, the driver wants to activate the AVH, but does not like to exit the AVH function by stepping on the accelerator, such as in tra...
