Embodiment 1

[0020] Embodiment 1: There are two protection mechanisms

[0021] Such as figure 1 As shown, it is a schematic diagram of the vehicle charging and driving interlocking system of the present invention having dual protection mechanisms. Here, protection mechanisms 1 and 4 (the numbering of the protection mechanisms will be described in the following embodiments) are selected as examples for details. illustrate. The system consists of a vehicle charging socket, a battery management system, a charging contactor, a motor controller, a vehicle controller, and a CAN bus connecting the above components. The vehicle charging socket outputs the charging connection confirmation signal CC2 to the battery management system BMS, and the BMS outputs the charging control negative signal to the charging contactor, and the vehicle controller connects the charging control negative signal through the collection line; at the same time, the battery management system BMS also sends a status report ...

Embodiment 2

[0024] Embodiment 2: with triple protection mechanism

[0025] Such as figure 2 As shown, it is a schematic diagram of the vehicle charging and driving interlocking system of the present invention having triple protection mechanisms. Here, protection mechanisms 1, 3, and 6 are selected as examples to illustrate in detail. The system consists of a vehicle charging socket, a battery management system, a charging contactor, a motor controller, a vehicle controller, and a CAN bus connecting the above components. The vehicle charging socket outputs a positive signal for charging control, and at the same time outputs a charging connection confirmation signal CC2 to the battery management system BMS, and the BMS outputs a negative signal for charging control; at the same time, the battery management system BMS also sends a status message to the vehicle controller; battery management The CAN bus signal is transmitted between the system BMS and the vehicle controller.

Embodiment 3

[0030] Embodiment 3: With four protection mechanisms

[0031] Such as image 3 As shown, it is a schematic diagram of the triple protection mechanism of the vehicle charging and driving interlocking system of the present invention. Here, the protection mechanisms 2, 3, 4, and 5 are selected as examples to illustrate in detail. The system consists of a vehicle charging socket, a battery management system, a charging contactor, a motor controller, a vehicle controller, and a CAN bus connecting the above components. The vehicle charging socket outputs a positive signal for charging control, and at the same time outputs a charging connection confirmation signal CC2 to the battery management system BMS, and the BMS outputs a negative signal for charging control; at the same time, the battery management system BMS also sends a status message to the vehicle controller; battery management The CAN bus signal is transmitted between the system BMS and the motor controller.

Abstract

The invention relates to a vehicle charging and travelling interlocking method, comprising a first protection mechanism or a second protection mechanism in the following six protection mechanisms, and at least one in the third to sixth protection mechanisms. The six protection mechanisms comprise: 1, when a vehicle power management system detects a charging connecting signal of a vehicle-mounted charging socket, sending a state information message to a vehicle control unit, executing a non-parking strategy; 2, when the vehicle power management system detects a charging connecting signal of a vehicle-mounted charging socket, sending a state information message to a motor controller, executing a non-parking strategy; 3, when a vehicle controller of a vehicle detects charging control positive signals, executing a non-parking strategy; 4, when the vehicle controller of the vehicle detects charging control negative signals, executing a non-parking strategy; 5, when the motor controller of the vehicle detects the charging control positive signals, executing a non-parking strategy; 6, when the motor controller of the vehicle detects the charging control negative signals, executing a non-parking strategy. The vehicle charging and travelling interlocking method has multiple protection mechanisms, thereby greatly improve security of vehicle charging and travelling interlocking.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an interlocking method with multiple protection mechanisms for vehicle charging and driving. Background technique [0002] As the use of electric vehicles becomes wider and wider, the safety features of electric vehicles are getting more and more attention, especially when the electric vehicle is in the charging state, because it involves the connection with the external power grid, the reliability and safety of the connection are particularly important. important. When the electric vehicle is in the charging state, it must be ensured that the electric vehicle cannot be driven by its own drive system, so as to avoid damage to the external charging equipment and ensure the safety of personnel. Therefore, certain interlocking measures must be taken between the charging connection and vehicle driving to ensure the safety of electric vehicles during charging. [0003] At present, ...
