Problems solved by technology

[0003] The current law requires that there must be a redundant parking system in the vehicle. The existing redundant parking system is mostly a mechanical parking brake (handbrake) and a power system parking (P gear). The control of the parking brake (handbrake) must be realized by the driver in the car, but in the remote vehicle driving scenario, the driver does not drive in the car, so the existing parking control method cannot meet the requirements of redundant parking. Remote vehicle control poses a huge security risk

Embodiment 1

[0038] figure 1 It is a flow chart of a vehicle parking control method provided by Embodiment 1 of the present invention. This embodiment of the present invention is applicable to the situation of vehicle parking. This method is applied to the main controller and can be executed by the vehicle parking device , the device can be realized by means of hardware and / or software, and the method includes the following steps:

[0039] Step 101 , when the switch signal of the parking switch is detected, determine the first working state of the main controller.

[0040] Wherein, the parking switch can be a trigger switch of the vehicle parking function, and can include a power system parking gear switch and an electronic parking switch, etc.; the switch signal can be a signal triggered when the parking switch is turned on and off, and can include analog signals and Numerical signals, etc.; the working state can be the mark of the current state of the main controller, which can be marke...

Embodiment 2

[0050] figure 2 It is a flow chart of a parking control method for a vehicle provided in Embodiment 2 of the present invention; the embodiment of the present invention is embodied on the basis of the above examples and applied to the main controller. The method provided in the embodiment of the present invention also includes:

[0051] Step 201 , when the switch signal of the parking switch is detected, determine the first working state of the main controller.

[0052] Specifically, a circuit or a sensor is used to monitor the switch signal of the parking switch. When a change in the switch signal is detected, it can be explained that the on-off state of the parking switch has changed, and the first working state of the main controller can be checked. Detection is performed to determine the state of the main controller.

[0053] Step 202: Generate master confirmation information based on the first working state and send it to the backup controller.

[0054] In the embodimen...

Embodiment 3

[0070] image 3 It is a flow chart of a vehicle parking control method provided by Embodiment 3 of the present invention. This embodiment of the present invention is applicable to the situation of vehicle parking. This method is applied to a backup controller and can be executed by a vehicle parking device , the device can be realized by means of hardware and / or software, and the method includes the following steps:

[0071] Step 301 , when the switch signal of the parking switch is detected, determine the second working state of the backup controller.

[0072] Wherein, the second working state may be the current state of the backup controller, which may include a normal state and a fault state.

[0073] Specifically, a circuit or a sensor can be used to monitor the switch signal of the parking switch. When a change in the switch signal is detected, it can be explained that the on-off state of the parking switch has changed, and the second work of the backup controller can be...

Abstract

The embodiment of the invention discloses parking control method and apparatus for a vehicle and the vehicle. The method includes the steps of determining a first operational state of a primary controller when a switch signal of a parking switch is monitored; generating primary confirmation information based on the first operational state and transmitting the primary confirmation information to abackup controller; and when the operating state is a normal state, generating a first control command based on the switch signal, and controlling vehicle parking by the first control command. According to the technical solution of the embodiment of the invention, the vehicle parking is controlled by the controllers, and interactive authentication is carried out between the controllers, thus improving the accuracy of the parking function, reducing the safety hazard of the vehicle parking and realizing remote vehicle control.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, in particular to a parking control method and device for a vehicle, and a vehicle. Background technique [0002] With the development of the times, cars have become an indispensable part of today's life, and remote vehicle control technology will develop rapidly. As an important part of the remote vehicle control field, the parking system has also developed rapidly, from a mechanical parking system to an electronic parking system. [0003] The current law requires that there must be a redundant parking system in the vehicle. The existing redundant parking system is mostly a mechanical parking brake (handbrake) and a power system parking (P gear). The control of the parking brake (handbrake) must be realized by the driver in the car, but in the remote vehicle driving scenario, the driver does not drive in the car, so the existing parking control method cannot meet the re...
