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 switching strategy suitable for a pure electric logistics vehicle. The vehicle mode switching strategy relates to a parking sleep mode, a pre-sleep mode, an ACC preparation mode, a power-on and power-off preparation mode, a second-gear power-on mode, a charging mode and a remote control mode. The vehicle mode switching strategy comprises the following working procedures that the vehicle is in the parking sleep mode when in the original state; in the parking sleep mode, the vehicle is aroused every one second to enter the pre-sleep mode; in the pre-sleep mode, the states of first-gear electricity and a charging gun are detected; if first-gear electricity is on, or the charging gun is plugged in, the vehicle enters the corresponding mode according to the states, otherwise the vehicle enters the parking sleep mode; and in the pre-sleep mode, if the first-gear electricity is on, the vehicle enters the ACC preparation mode. According to the vehicle mode switching strategy suitable for the pure electric logistics vehicle, the vehicle modes of the pure electric logistics vehicle are acquired. In different vehicle modes and for specific components, controlling is conducted, and thus the load rate of a vehicle control unit is lowered. By setting the vehicle mode switching strategy, the logical sequence of control over all components is fixed, and 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...
