Embodiment 1

[0038] likefigure 1 As shown, this embodiment provides a protective device for an all-terrain control system, which includes: a sending module 1, configured to send to the vehicle operation subsystem 4 the triggering signal generated by the user operating the terrain mode switch of the all-terrain control system. The corresponding terrain mode signal; the receiving module 2 is used to receive the terrain mode confirmation signal generated by the vehicle operation subsystem 4 in response to the terrain mode signal sent by the sending module; and the control module 3 is used to operate the vehicle again In the case of the terrain mode switch, according to the terrain mode confirmation signal and the preset terrain mode signal priority, control whether the sending module sends the corresponding terrain mode signal triggered by the user operating the terrain mode switch again .

[0039] Wherein, the signal sending is controlled by the preset terrain mode signal priority, which is ...

Embodiment 2

[0061] The inventive idea of ​​this embodiment is the same as that of the first embodiment above, as Figure 4 As shown, the present embodiment proposes a protection method for an all-terrain control system, and the protection method for the all-terrain control system mainly includes the following steps:

[0062] Step S1 , sending the corresponding terrain mode signal triggered by the user operating the terrain mode switch to the vehicle operation subsystem.

[0063] Step S2, receiving a terrain mode confirmation signal generated by the vehicle operating subsystem in response to the corresponding terrain mode signal sent in step S1.

[0064]Step S3, when the user operates the terrain mode switch again, according to the terrain mode confirmation signal and the preset terrain mode signal priority, control whether to execute step S1 again to send the user to operate the terrain again. The corresponding terrain mode signal is generated by triggering the mode switch. Among the pr...

Embodiment 3

[0104] This embodiment provides an all-terrain control system, and the all-terrain control system is provided with the protection device described in the first embodiment. The structure of the all terrain control system can refer to figure 2 , which also includes conventional supporting equipment such as IP system and terrain mode switch.

Abstract

The invention relates to the vehicle technology field and provides a protection device and method of a full landform control system and a full landform control system. The protection device of the full landform control system comprises a transmission module, a receiving module and a control module. The transmission module is used for transmitting a corresponding landform mode signal generated by triggering from a user operating a landform mode switch to a vehicle operation subsystem. The receiving module is used for receiving a landform mode confirmation signal generated by the vehicle operation subsystem responding to the landform mode signal. The control module is used for controlling the transmission module to transmit or not transmit the landform mode signal which is generated throughtriggering by a user re-operating the landform mode switch according to priorities of a landform mode confirmation signal and a preset landform mode signal under a condition that the user is re-operating the landform mode switch, wherein a 4L mode signal has a highest priority. The protection device and method of a full landform control system can solve a problem of teeth beating of a transfer case which is caused by non-coordination between the vehicle operation subsystems.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a protection device and method for an all-terrain control system and an all-terrain control system. Background technique [0002] Terrain Control is an electronically controlled driver assistance system that helps inexperienced persons navigate the vehicle in various terrain modes with ease. In the all-terrain control system, the user triggers the all-terrain switch device (or known as the all-terrain switch module, All-Terrain Switching Model, ATSM) by operating the terrain mode selection switch to issue commands, and the vehicle operation subsystem is carried out through the LIN bus and CAN network. The signal is sent and received in response to the command, and the subsystems mainly involved in the response are the Engine Management System (EMS), the Transmission Control Unit (TCU), the Transfer Case (Torque-On-Demand, TOD), electronic differential (EGerodisc Di...
