Control method and device of hybrid power vehicle, medium, equipment and vehicle

Abstract

The invention relates to a control method and device of a hybrid power vehicle, a medium, equipment and the vehicle. The hybrid power vehicle comprises a P2 motor, and the method is characterized by comprising the steps that if an instruction for indicating the hybrid power vehicle to start running is received, or in the running process of the hybrid power vehicle, whether a power battery meets running conditions or not is judged; if it is judged that the power battery does not meet the operation condition, an engine is controlled to drive the P2 motor to operate; and if the rotating speed of the P2 motor reaches the preset rotating speed, controlling the P2 motor to output voltage to supply power to a low-voltage storage battery. Thus, if the power battery is low in temperature or breaks down, normal starting and running of the whole vehicle can be guaranteed under the condition that the engine is not provided with a generator, and dangers caused by sudden power interruption during running are avoided.

Description

technical field [0001] The present disclosure relates to the field of hybrid vehicle control, in particular, to a hybrid vehicle control method and device, medium, equipment, and vehicle. Background technique [0002] A hybrid vehicle usually refers to a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), that is, a vehicle using a traditional internal combustion engine (diesel engine or gasoline engine) and an electric motor as power sources. [0003] There are two ways to deal with the low temperature of the power battery (the temperature does not reach the minimum temperature required for starting the power battery) or failure of the current hybrid vehicle: method 1), the engine is equipped with a starter, and the engine is started by the starter to make the vehicle enter the driving state state; method 2), the engine is equipped with a starter and a generator, and the engine is started by the starter to make the vehicle enter a drivable state, and at the same time, t...

AI Technical Summary

Problems solved by technology

[0004] The above treatment methods have certain disadvantages. Method 1) can only support short-term driving of the whole vehicle, and cannot drive when the low-voltage battery is feeding power.

For example: when the vehicle is in a low-temperature environment, the power battery cannot work, and the system prohibits high-voltage connection. At this time, the engine is started to drive the vehicle, but when the battery feeds power, the power is interrupted, which affects driving safety.

Method 2) can support the normal driving of the whole vehicle, but the engine equipped with a generator will increase the cost of the whole vehicle
