As shown in fig. 1, in an embodiment, the method for managing the entire vehicle power mode of the electric vehicle of the present invention includes the following steps:
step S1, dividing the power mode of the whole vehicle into an OFF mode, an ACC mode and an ON mode; the OFF mode includes a 12V relay OFF mode and a 12V relay pre-OFF mode.
Specifically, in the invention, the power modes of the whole vehicle are divided into the following three types:
(1) OFF mode
Specifically, the OFF mode includes the following two sub-modes:
a)12V Relay OFF mode (12V OFF)
In this mode, the 12V relay is open and the low voltage network is de-energized.
b)12V Relay Pre-OFF mode (PRE 12V OFF)
In this mode, the 12V relay is closed and the low voltage network is energized.
(2) In the ACC mode, a 12V relay is closed, high-voltage power can be electrified, and actions of each controller can be customized.
(3) ON mode
In this mode, the 2V relay is closed, the drive output is enabled, the high voltage must be powered up, and each controller action can be customized.
And step S2, switching the electric automobile to the corresponding whole automobile power mode based on the trigger information of the whole automobile power mode.
Specifically, a key is not needed to start the switch, trigger information is generated based on a vehicle key, the IMMO, a vehicle door switch state, a brake pedal switch, a vehicle lock, an intelligent key and the like, and the corresponding vehicle power mode is switched based on the trigger information, so that the automatic switching of the vehicle power mode is realized.
As shown in fig. 2, in an embodiment of the present invention, in the 12V relay off mode, when the vehicle is waken up by a non-key, the mode is switched to the 12V relay pre-off mode; and under the 12V relay pre-closing mode, a low-voltage power-off timer counts time, and when the low-voltage power-off timer times out, the 12V relay closing mode is switched to.
In the OFF mode, when a valid key is detected within a preset length range, a vehicle door is unlocked, a brake is stepped on, and an in-vehicle key is detected, the internal function of the vehicle is triggered or an automatic parking request is received, switching to the ACC mode; and when the vehicle is turned off or locked by the central control screen soft switch in the ACC mode, switching to the 12V relay pre-turn-off mode. Preferably, the preset length is 5 m.
In the ACC mode, when IMMO passes authentication or receives an automatic parking request, switching to the ON mode; and under the ON mode, when the gear is in a non-P gear, the vehicle speed is lower than a preset value, and the cab door is changed from a closed state to an open state, the ACC mode is switched. The IMMO (Immobilizer) is an engine anti-theft locking system, is developed on the basis of a general VATS (variable access System), and passes the idea of VATS on the anti-theft principle, namely, the password of a chip in a key is matched with the password in a starting switch to control the starting of the engine so as to achieve the anti-theft purpose. For the automobile provided with the engine anti-theft locking system, even if a vehicle stealer opens the door, the engine cannot be started to drive away the automobile.
In the ON mode, the vehicle includes a driving state and a non-driving state. When the vehicle is in a non-driving state, if the brake is stepped on and the gear is engaged with the P gear, the vehicle is switched to a driving state; when the vehicle is in a driving state, if the gear is in a P gear, the gear is switched to a non-driving state, and a time delay timer (Ton timer) is switched on to start timing. When the on-delay timer is overtime or a cab door is changed from a closed state to an open state, switching to the ACC mode; when the central control screen soft switch closes or locks the vehicle, the ACC mode is switched to the 12V relay pre-closing mode.
Sending OFF mode information to the CAN bus at set time intervals in the 12V relay pre-closing mode; transmitting ACC mode information to the CAN bus at set time intervals in the ACC mode; and ON mode information is sent to the CAN bus at set time intervals in the ON mode, so that the vehicle power supply mode control system CAN know the vehicle power supply mode information in real time.
As shown in fig. 3, in an embodiment, the entire vehicle power mode management system of the electric vehicle of the invention includes a dividing module 31 and a switching module 32.
