Embodiment Construction

[0082] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0083] figure 1 It is a flow chart of a vehicle power-on control method shown according to an exemplary embodiment of the present disclosure, as shown in figure 1 As shown, the method is applied to the vehicle controller of the vehicle, and the method includes the following steps:

[0084] Step 101, when a low voltage activation signal is detected, it is detected whether there is a fault in the vehicle.

[0085] Among them, the low-voltage activation signal means that the KEY ON signal (that is, the KL15 signal) is valid. Usually, within 200ms after the KL15 signal is detected, the vehicle controller needs to complete the initialization and send the first f...

Abstract

The invention discloses a power-on control method and device for a vehicle. The power-on control method comprises steps of detecting whether a vehicle has a fault when a low-pressure activation signal is detected, controlling high-voltage connection according to a vehicle high-voltage connection condition and a vehicle control state when the fault does not exist, determining whether enable of a DC converter and a motor controller is normal when the vehicle enters a high-voltage state, outputting first prompt information to indicate that vehicle driving is ready via an instrument when enable of the motor controller and the DC converter is normal. The vehicle control state is formed by a vehicle shift, a brake pedal and a charging state. Power-on operation can be conducted when the vehicle is ensured to be at a normal state, so electric vehicle high-voltage safety can be guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a method and device for power-on control of a vehicle. Background technique [0002] The start-up of new energy vehicles, especially electric vehicles, is different from that of traditional vehicles. To ensure the safety of high-voltage functions of electric vehicles and improve the service life of high-voltage components, it is very important to design a reasonable high-voltage power-on and power-off control strategy. The vehicle controller (Vehicle Controller) of electric vehicles is the core component of the vehicle control system of electric vehicles. Compared with the dynamic control of each component controller, the vehicle controller belongs to the management coordination type control. The whole vehicle system adopts the architecture of vehicle control system with integrated integrated control and distributed processing. Each component has an independent co...
