Problems solved by technology

[0002] With the gradual development of unmanned driving technology, people have higher and higher safety requirements for unmanned vehicles. Since the safety of unmanned driving is closely related to the gear control of unmanned vehicles, how to improve the safety of unmanned vehicles The safety of gear control and the improvement of the safety of unmanned driving have become issues that need to be considered, and the current unmanned vehicle gear control technology is mainly designed based on the network architecture of unmanned vehicles. When the network architecture changes, the corresponding gear control method also needs to be adjusted. Therefore, the existing unmanned vehicle gear control technology still has problems of low security and low universality.

Embodiment 1

[0026] An embodiment of the present invention provides a gear position control method, see figure 1 The gear position control method flow chart shown in the figure can be applied to the vehicle controller. The vehicle controller and the unmanned industrial computer are connected through the controller area network (Controller Area Network, CAN) bus communication. The method mainly Including the following steps S102 to S104:

[0027] Step S102, receiving the control command sent by the unmanned industrial computer.

[0028] The above control instructions include the target gear and / or the target braking force. When the unmanned vehicle needs to switch gears, the unmanned industrial computer sends a gear control instruction to the vehicle controller. The gear control instruction includes the unmanned vehicle In order to ensure the safety of unmanned vehicle gear control, the unmanned industrial computer can also send a target braking force with a certain value to the vehicle co...

Embodiment 2

[0050]On the basis of the foregoing embodiments, this embodiment provides an example of applying the foregoing gear position control method to control the gear position of the unmanned vehicle, assuming that the initial state of the unmanned vehicle is in the P gear, and the unmanned vehicle includes For components such as vehicle controller, parking motor controller, brake controller, and unmanned industrial computer, please refer to the following steps (1) to (2) for details:

[0051] Step (1): The parking motor controller generates a control command according to the target task input by the user, and sends the control command to the vehicle controller.

[0052] Among them, the above-mentioned vehicle controller, parking motor controller, brake controller and unmanned industrial computer realize communication through the CAN bus, and the above-mentioned parking motor controller has a ramp assist function (when the parking motor When the controller detects that the vehicle is...

Embodiment 3

[0064] For the gear position control method provided in Embodiment 1, the embodiment of the present invention provides a gear position control device, see image 3 A schematic structural diagram of a gear position control device is shown, which includes the following modules:

[0065] The instruction receiving module 31 is configured to receive the control instruction sent by the unmanned industrial computer; wherein, the control instruction includes a target gear position and / or a target braking force.

[0066] The gear position control module 32 is used to obtain the current state of the target vehicle, and perform gear position control based on the control command and the current state; wherein, the vehicle controller is set in the target vehicle, and the current state includes the current parking state and / or the current state. speed.

[0067] The gear position control device provided in this embodiment automatically controls the gear position of the unmanned vehicle base...
