AI Technical Summary

Technical Problem

In the series drive mode of hybrid vehicles, the state of charge of the power battery is prone to continuous decline under high load conditions, leading to the risk of power battery depletion. Existing technologies are difficult to effectively prevent power battery depletion.

Method used

By monitoring the output parameters of the power battery in real time, the upper limit of the vehicle's driving torque is adjusted to avoid over-discharge of the power battery, ensure that the state of charge is always within the allowable range, and sacrifice vehicle power performance when necessary to prevent battery depletion.

Benefits of technology

It effectively prevents the power battery from running out of power, extends the battery's lifespan, and ensures the vehicle's power performance within the allowable range of state of charge.

Abstract

The application discloses a hybrid vehicle control method and system and a hybrid vehicle, and prevents power batteries from being discharged in a series driving mode of the hybrid vehicle. The method comprises the following steps: in response to an instruction for controlling the hybrid vehicle to enter the series driving mode, acquiring an output parameter of the power batteries; and adjusting an upper limit value of a driving torque of the whole vehicle according to the output parameter, so that the output parameter is always within an allowable range.
