Embodiment Construction

[0023] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0024] Such as figure 1 As shown, a vehicle mode conversion strategy suitable for pure electric logistics vehicles, which includes the following modes: parking sleep mode, pre-sleep mode, ACC preparation mode, power on and off preparation mode, second-speed power on mode, charging mode and remote control mode;

[0025] Parking sleep mode: In this mode, the vehicle controller turns off all devices to reduce the power consumption of the vehicle; in this mode, it wakes up every 1 second and enters the pre-sleep mode;

[0026] Pre-sleep mode: In this mode, the vehicle controller detects whether the ACC power / charging gun signal (Charge_plug_in) is valid. If it is valid, it will enter the corresponding mode. If it is invalid, it will return to ...

Abstract

The invention discloses a vehicle mode conversion strategy suitable for pure electric logistics vehicles, including a parking sleep mode, a pre-sleep mode, an ACC preparation mode, a power-on and power-on preparation mode, a second-speed power supply start mode, a charging mode and a remote control mode; Its working process is as follows: the vehicle is in the parking sleep mode in the initial state, and wakes up every 1 second in this mode to enter the pre-sleep mode. When the electric gear is on or the charging cable is plugged in, it will enter the corresponding mode according to the state, otherwise it will return to the parking sleep mode; in the pre-sleep mode, if the first gear is on, it will enter the ACC preparation mode; etc. The present invention obtains the complete vehicle mode of the pure electric logistics vehicle, and controls specific components in different complete vehicle modes, thereby reducing the load rate of the complete vehicle controller. Through the setting of the vehicle mode conversion strategy, the logic sequence of the control of each component is solidified, and the misoperation of the vehicle is avoided.

Description

technical field [0001] The invention belongs to the field of pure electric vehicle control, and in particular relates to a vehicle mode conversion strategy suitable for pure electric logistics vehicles. Background technique [0002] Facing the increasingly serious energy shortage and environmental deterioration, the development and utilization of new vehicles has been paid more and more attention by governments and industries of various countries. In this context, clean, pollution-free, zero-emission pure electric logistics vehicles have become one of the most promising means of transportation today. [0003] At present, the control method of pure electric logistics vehicles is completed by the vehicle controller based on component control. Usually, the vehicle controller controls each component in real time by collecting the information of each component during the operation of the vehicle, and judges whether the vehicle is in a fault state, and if so, performs power-limit...
