Embodiment Construction

[0066] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0067] The present invention can determine that the whole vehicle has been powered off after the whole vehicle is powered off, for example, when the whole vehicle is in the OFF gear, and once part of the controllers meet the dormancy conditions, they will enter the dormant state, for example, the whole vehicle is in the OFF gear, and there is no power off. When the instruction to play the broadcast is received, the controller playing the broadcast can enter the dormant state without waiting for all the controllers to meet the dormant cond...

Abstract

The invention provides a vehicle control method and system. The vehicle control method comprises the steps that after a whole vehicle is powered off, a main controller and all auxiliary controllers monitor whether self hard-wire ports meet the dormant condition or not; if the auxiliary controllers meet the dormant condition, a dormant request message is sent to a CAN bus, and the auxiliary controllers enter a dormant state till receiving the dormant request message sent by the main controller; after the main controller receives a dormant request message sent by the auxiliary controllers, whether the auxiliary controllers are allowed to be dormant is judged; if yes, the dormant request message is sent to the auxiliary controllers through the CAN bus; if the main controller meets the dormant condition and all the auxiliary controllers enter the dormant state, the main controller enters the dormant state; and after all the controllers enter the dormant state, the CAN bus enters the dormant state. By means of the vehicle control method and system, the problem that a vehicle storage battery losses electricity due to the fact that a dormancy awakening method requires all controllers to be simultaneously dormant or awakened in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a vehicle control method and system. Background technique [0002] When the whole vehicle is in the OFF gear, some functions need to be completed, such as the instrument or the indicator light to display the door open and closed status, the body controller can respond to the control of the remote control key, the setting of the reverse mirror memory ON gear and so on. In order to realize these functions, these controllers need to have power supply to realize these controls when the whole vehicle is in OFF gear. Since the engine will not charge the battery when the vehicle is in the OFF gear, the controller will cause the power consumption of the battery; in order to prevent the battery from running low, these controllers are required to enter a low power consumption state when they are not working, that is, a sleep state ; When the controller receives a wake-up signal...
